Overclocker der8auer has posted a video demonstrating the delidding process of the AMD Ryzen 5 2400G, and his findings on its effect on temperatures and overclocking headroom.

The full video is embedded below:
The results are interesting, but disappointing from an overclocking standpoint, as he was only able to increase his highest frequency by 25 MHz. Thermals were far more impressive, as the liquid metal used in place of the factory TIM did lower temps considerably.
Here are his temperature results for both the stock and overclocked R5 2400G:
The process was actually quite straightforward, and used an existing Intel delidding tool (the Delid Die Mate 2) along with a small piece of acrylic to spread the force against the PCB.

The Ryzen 5 2400G is using thermal paste and is not soldered, which enables this process to be reasonably safe - or as safe as delidding a CPU and voiding your warranty ever is. Is it worth it for lower temps and slight overclocking gains? That's up to the user, but integration of an APU like this invites small form-factors that could benefit from the lower temps, especially with low-profile air coolers.

EVGA is launching a new Pascal-based graphics card with a thicker 2.5 slot cooler in the form of the GeForce GTX 1070 Ti FTW Ultra Silent. The new graphics card has a sleek gray and black shroud with two large black fans in standard ACX 3.0 cooler styling, but with a much thicker cooler that EVGA claims enables more overclocking headroom or a nearly silent fan profile on stock settings.
The GTX 1070 Ti FTW Ultra Silent is powered by two 8-pin PCI-E power connectors that feed a 10+2 power phase and enables the cards 235W TDP (reference TDP is 180 watts). The 2432 Pascal GPU cores are clocked at 1607 MHz base and 1683 MHz boost which aligns with NVIDIA's reference specifications. While there are no guaranteed factory overclock here, EVGA is bundling the dual BIOS card with its EVGA Precision XOC and Precision OC Scanner X software for one-click overclocking that dynamically pushes the clocks up to find the optimal overclock for that specific card. The 8GB of GDDR5 memory is also stock clocked at 8008 MHz. Other features include a backplate, white LEDs, and 2-way SLI support.
Display outputs include one HDMI 2.0b, three DisplayPort 1.4, and one DVI port.
The new FTW series graphics card is available now from the EVGA website for $499.99 and comes with a three year warranty.
The graphics card appears to be rather tall, and I am curious how well the beefier heatsink performs and just how "ultra silent" those fans are! Hopefully we can get one in for testing! The $499.99 MSRP is interesting though because it lines up with the MSRP of the GTX 1080, but with the state of the GPU market as it is the price is not bad and actually comes in about in the middle of where other GTX 1070 Ti cards are at. My guess is they will be snatched up pretty quickly so it's hard to say if it will stay at that price especially on third party sites.

A new CPU means new overclocking challenges and with it comes a new batch of refreshed Z370 motherboards. At the high end, the current frequency record for the Core i7 8700K is 7,405.1 MHz obtained by Hovan Yang using a MSI Z370 Godlike Gaming motherboard.
He’s not the only one testing the limits of Intel’s new six core processors though. Asus held an overclocking event a few weeks ago where renowned overclockers Alex@ro, elmor, der8auer, Rsannino, and shamino battled it out. Der8auer got a pre-release crack at the i7 8700K at the event and after de-lidding and replacing the TIM with liberal amounts of Kryonaut thermal paste managed to achieve 6.8 GHz using 1.8 volts and a 68x multiplier (and bumping the cache speed up to 6.3 GHz). With these settings on the monster Maximus X Apex motherboard, he scored 299 in single threaded and 2253 in multithreaded in Cinebench R15. Der8auer compared this benchmark result to Skylake X at 5.5 GHz scoring 237 in the single threaded test. Following the benchmark run, he went for the highest CPU-z validated clockspeed he could hit and managed to push the chip to 7300 MHz (100MHzx73). From there overclocker Alex from Romania was able to overclock his i7 8700K to 6844 MHz and scored 2306 in Cinebench R15.
The overclockers broke 10 new records in the six core CPU category and also managed to break a DDR4 clockspeed record by pushing a single 8GB G.Skill DIMM to 5529.2 MHz at 24-31-31-63-3 timings!
Also of note is that Coffee Lake does not depend of FIVR so overclockers are able to use a full pot of liquid nitrogen (or liquid helium) to cool the processor down to much lower temperatures so that they can crank up the voltage and achieve much higher clockspeeds than Skylake-X which cannot boot if temperatures are too low.
While the ASUS team does not hold the clockspeed record anymore (though they might regain it with some Liquid Helium), der8auer has an interesting video and Asus has a blog post with photos talking about the process, setup, and everything that goes into these extreme overclocking sessions including pre-binning the chips, preparing the IHS and motherboard for the super cold (-185°C to -190°C) temperatures, and keeping the processors and motherboards running. For example, and Josh will be interested in this, part of the process of preparing the motherboard involves slathering it in Vaseline!
If you are interested in this extreme overclocking stuff it gives a bit of insight into all the fun to be had!

In response to a few questions readers have brought up about the NICs on the MSI Z370 Godlike Gaming; this board to features the Killer xTend technology from Rivet Networks we saw at Computex. The three Killer Ethernet ports and Killer WiFi allow you to use your PC as both a network switch and a WiFi extender. Several of GIGABYTE's AORUS Gaming motherboards will also feature this technology.
*******************Now back to your regularly scheduled PR******************
MSI is entering the Z370 motherboard fray with two flagship boards the ATX MSI Z370 Gaming Pro Carbon AC and the E-ATX Z370 Godlike Gaming. The latter board takes Z370 to the extreme with more power phases, cooling, expansion, and, of course, RGB LEDs!
The massive motherboard features a massive digital power delivery with solid aluminum heatsinks to keep them cool as well as show off RGB bling. MSI did not specify how it has divided up the phases or the number, but there’s as many as 18 power phases (in reality likely less). Power inputs include both an 8-pin and 4-pin EPS connections along with the standard ATX 12V 24-pin and a 6-pin connector to supply extra power to the PCI-E slots. There are four steel shielded DDR4 DIMM slots with dedicated digital PWM power delivery supporting up to 64 GB at 4133 MHz.
The Z370 Godlike Gaming further features four steel reinforced PCI-E x16 slots, a single PCI-E x1 slot, and three M.2 (key M) slots (using the included PCI-E riser card you can get two extra M.2 slots). On the traditional storage front, the motherboard has six SATA 6 Gbps and one U.2 port. RGB support comes in the form of MSI’s own “Mystic Light” technology that includes on board LEDs as well as a header for RGB strips (and MSI’s site shows the board comes with a Phanteks branded RGB strip) that can be controlled with software. As far as cooling there are headers for a CPU fan, water pump, and eight system fans.
MSI is using a Killer 1535 chip for 802.11ac Wi-Fi (2x2) as well as three Killer E2500 Gigabit Ethernet NICs. Audio is handled by “MSI Audio Boost” which is two Realtek ALC 1220 based EMI shielded audio processors along with an ESS DAC and amplifier with gold plated audio jacks (including a ¼” jack for high end headphones). MSI claims the LED bordered isolated power audio design includes separate PCB layers for the left and right audio channels and high end WIMA and Nichicon capacitors.
Around back the MSI Z370 Godlike Gaming includes:
- 2 x Wi-Fi antenna connections
- 1 x PS/2
- 2 x USB 2.0
- 1 x USB 3.1 Gen 2 Type-C
- 1 x USB 3.1 Gen 2 Type-A
- 6 x USB 3.1 Gen 1 Type-A
- 3 x Gigabit Ethernet (Killer E2500)
- 7 x Audio
- 5 x 3.5mm
- 1 x 6.35mm
- 1 x S/PDIF
Users can get additional USB 3.1 ports using internal headers powered by ASMedia ASM3142 and ASM1074 chipsets (Gen 2 and Gen 1 respectively).
Retail versions of the motherboard should come with a PCI-E riser card with two M.2 slots, headphone adapter, custom sleeved SATA cables, three I/O backplates, three 2-pin temperature probes, a SLI bridge, and a 400mm LED strip.
I am interested in this board from an overclocking perspective as the beefy power phases and additional CPU power from the 8+4 pin connectors should allow for some extreme overclocking fun to be had and enable higher everyday stable overclocks as well. This board has just about everything you could want from a high-end motherboard (except Intel NICs, 10 GbE, and Thunderbolt but you can't have everything!), but it is sure to come at a hefty premium. MSI is not yet talking pricing or availability though unfortunately.

Tagged: aorus, gigabyte, coffee lake, Z370, Z370 AORUS, RGB LED, gaming, overclocking
This week Gigabyte took the wraps off its lineup of Z370 motherboards that will support Intel’s 8th Generation Coffee Lake processors. The new lineup is comprised of five models that incorporate Gigabyte Ultra Durable technology, Dual BIOS, server grade digital power delivery, ESS Sabre DAC, a high-quality headphone amplifier, M.2 thermal guards, RGBW and Digital LED headers, and support for monitoring and control of fans and water pumps using RGB Fusion and Smart Fan 5 respectively. At the top of the lineup is the Gigabyte Z370 Aorus Gaming 7 which appears to have a lot to offer for enthusiasts planning a Coffee Lake build.
The LGA 1151 socket is surrounded by an improved digital VRM setup that is rated at 60A per power phase. The board uses 10K Ultra Durable Black capacitors as well. The VRMs are cooled by large aluminum heatsinks as well as a small fan tucked away under the “thermal armor” above the rear I/O panel connectors. Using Gigabyte’s Smart Fan 5 technology, the built-in fan as well as CPU and case fans can be set to stop when the PC is idle and only spin up when needed.
Speaking of cooling, the board has eight fan/water pump Hybrid Fan headers (one is rated at 3A) and nine temperature sensors.
There are four DDR4 DIMM slots to the right of the processor socket that support up to 4400 MHz memory clockspeeds. Storage is handled by six SATA 6Gbps ports, two M.2 (PCI-E/SATA), and one smaller PCI-E M.2 slot with support for Intel’s Optane Memory technology. Expansion slots include three PCI-E x16 slots (x16/x8/x4) and three PCI-E x1 slots. Other internal headers include a USB 3.1 Gen 2 Type-C front panel, additional USB 3.1 Gen 1 ports, two RGBW LED headers, two Digital LED headers, two temperature sensor headers, and one Thunderbolt 3 Add-in card header. Power, reset, OC, and Clear CMOS buttons are also included on the board to make running it on a test bench and overclocking a bit easier.
For the RGB fans, there are several lighting zones on this board including on the VRMs, on the “Thermal Armor”, around the DIMM slots, around the PCI-E x16 slots, on the Z370 chipset heatsink, and a LED strip along the right side of the board that you can customize the look of with a 3D printer.
In addition to the Z370 chipset, Gigabyte is also using ASMedia silicon for additional USB 3.1 Gen 2 ports, a Realtek chip for a USB 3.1 Gen 1 hub, Intel GbE LAN and Rivet Networks Killer E2500 NIC for Gigabit Ethernet, and Realtek ALC1220 audio codec for audio.
On the audio front, Gigabyte is spicing things up a bit by pairing that Realtek ALC1220 audio codec with an ESS9018Q2C DAC, Nichicon and WIMA audio capacitors, independent analog power(LME49720), a smart headphone amp (auto-detects impedance), gold plated audio jacks, and support for USB DAC-UP 2 technology (adjustable voltage to compensate for voltage drop).
Around back the Aorus Gaming 7 features:
- 1 x PS/2
- 1 x DisplayPort
- 1 x HDMI
- 5 x USB 3.1 Gen 1
- 1 x USB 3.1 Gen 2 Type-C
- 1 x USB 3.1 Gen 2 Type A
- 2 x RJ45 (Gigabit Ethernet)
- 1 x S/PDIF
- 5 x 3.5mm audio out.
It appears that Gigabyte has packed a lot of hardware into its flagship Z370 motherboard, and with the actively cooled VRMs it should be a decent overclocker even when using water cooling for the CPU (though noise from the small fan might be an issue). Unfortunately, Gigabyte has not yet released pricing information. On the bright side, there are several models in the Aorus Z370 lineup for those that do not want the Killer networking, third PCI-E x16 slot, as many LEDs, or ESS Sabre audio where there is room to save some money to put towards a graphics card or monitor. I'll leave it up to Sebastian and Morry to determine if the audio is audiophile and CMOS placement is good enough respectively.
What are your thoughts on the Aorus Z370 lineup? Is it enough to entice you to upgrade to Coffee Lake?

Renowned overclocker der8auer got his hands on the new 18-core Intel Core i9-7980XE and managed to break a few records with more than a bit of LN2 and thermal paste. Following a delid, der8auer slathered the bare die and surrounding PCB with a polymer-based (Kryonaut) TIM and reattached the HIS to prepare for the extreme overclock. He even attempted to mill out the middle of the IHS to achieve a balance between direct die cooling and using the IHS to prevent bending the PCB and spread out the pressure from the LN2 cooler block, but ran into inconsistent results between runs and opted not to proceed with that method.
Using an Asus Rampage VI Apex X299 motherboard and the Core i9-7980XE at an Asus ROG event in Taiwan der8auer used liquid nitrogen to push all eighteen cores (plus Hyper-Threading) to 6.1 GHz for a CPU-Z validation. To get those clockspeeds he needed to crank up the voltage to 1.55V (1.8V VCCIN) which is a lot for the 14nm Skylake X processor. Der8auer noted that overclocking was temperature limited beyond this point as at 6.1 GHz he was seeing positive temperatures on the CPU cores despite the surface of the LN2 block being as low as -100 °C! Perhaps even more incredible is the power draw of the processor as it runs at these clockspeeds with the system drawing as much as 1,000 watts (~83 amps) on the +12V rail with the CPU being responsible for almost all of that number! That is a lot of power running through the motherboard VRMs and the on-processor FIVR!
For comparison, at 5.5 GHz he measured 70 amps on the +12V rail (840W) with the chip using 1.45V vcore under load.
For Cinebench R15, the extreme overclocker opted for a tamer 5.7 GHz where the i9-7980XE achieved a multithreaded score of 5,635 points. He compared that to his AMD Threadripper overclock of 5.4 GHz where he achieved a Cinebench score of 4,514 (granted the Intel part was using four more threads and clocked higher).
To push things (especially his power supply heh) further, the overclocker added a LN2 cooled NVIDIA Titan Xp to the mix and managed to overclock the graphics card to 2455 MHz at 1.4V. With the 3840 Pascal cores at 2.455 GHz he managed to break three single card world records by scoring 45,705 in 3DMark 11, 35,782 in 3DMark Fire Strike, and 120,425 in 3DMark Vantage!
Der8auer also made a couple interesting statements regarding overclocking at these levels including the issues of cold bugs not allowing the CPU and/or GPU to boot up if the cooler plate is too cold. On the other side of things, once the chip is running the power consumption can jump drastically with more voltage and higher clocks such that even LN2 can’t maintain sub-zero core temperatures! The massive temperature delta can also create condensation issues that need to be dealt with. He mentions that while for 24/7 overclocking liquid metal TIMs are popular choices, when extreme overclocking the alloy actually works against them because the sub-zero temperatures reduce the effectiveness and thermal conductivity of the interface material which is why polymer-based TIMs are used when cooling with liquid nitrogen, liquid helium, or TECs. Also, while most people apply a thin layer of thermal paste to the direct die or HIS, when extreme overclocking he “drowns” the processor die and PCB in the TIM to get as much contact as possible with the cooler as every bit of heat transfer helps even the small amount he can transfer through the PCB. Further, FIVR has advantages such as per-core voltage fine tuning, but it also can hold back further overclocking from cold bugs that will see the processor shut down past -100 to -110 °C temperature limiting overclocks whereas with an external VRM setup they could possibly push the processor further.
For the full scoop, check out his overclocking video. Interesting stuff!

Corsair has launched a new Vengeance LPX DDR4 memory kit that is capable of hitting 4600 MHz at 1.5 volts. The new kit is a 16GB (2 x 8GB) kit that Corsair reportedly co-developed with AsRock for fine tune using their X299 OC Formula motherboard. The DDR4 kit is made using hand sorted Samsung B-dies and it supports Intel XMP 2.0 standards allowing it to clock at 4600 MHz with a single setting change in the UEFI.
The Vengeance LPX DIMMs run with CAS timings of 19-26-26-46 and need only 1.5V to clock at 4600 MHz. This kit will be ideal for Intel’s X299 as well as AMD’s X399 platforms. While Ryzen and Threadripper platforms may need a bit more tweaking to get working, they would benefit the most from the higher clocked memory allowing the Infinity Fabric to clock higher.
Being one of the highest factory clocked DIMMs, they come at a cost. The new RAM kit (CMK16GX4M2F4600C19) is available now for $549.99 with a lifetime limited warranty.
For something a bit more tame, earlier this week Corsair launched a 2 x 8GB kit (CMK16GX4M2F4500C19) clocked at 4500 MHz with CL19-19-19-39 timings (at 1.45V) that is also available now for $479.99 MSRP. Enthusiasts might be better off buying the cheaper kit and overclocking them (though not guaranteed and might need a bit more than 1.5V) while workstation and enterprise customers with corporate expense accounts can opt for the more expensive but factory clocked 4600 MHz kit.
At time of writing the new kits were not up on Amazon yet, but they should be shortly. You can find the cheaper 4500 MHz kit on Corsair's web store but it is listed at $504.99 currently. If you wait a bit, that price should go down closer to MSRP as other retailers put up their listings.

Tagged: XSPC, amd, Threadripper, overclocking, Raystorm
For those convinced that the Threadripper is being held back by poorly endowed partners, [H]ard|OCP received the new XSPC RayStorm which has a cold plate as large as Threadrippers heatspreader. As you can see from the picture, new habits will need to e learned when spreading the TIM on such a large area so keep an eye out for tips or carefully experiment on your own. The heatsink let [H] reach a solid 4GHz on all 16 cores with a 3200MHz memory clock, at significantly lower voltages than Ryzen required to reach the same frequency. Even better news is that this is not the limit, [H] intends to test again using a more powerful radiator and expects to see an even better overclock.
"XSPC got us over one of its first waterblocks specifically designed to help handle Ryzen Threadripper CPU's heat while overclocking. We give you a quick unboxing, break down the block itself, and then we look at Threadripper long-term performance. We finally get it dialed in at 4GHz."

Asus recently took the wraps off of its X370 ROG Crosshair VI Extreme E-ATX motherboard which is the company’s new flagship motherboard for the AMD Ryzen platform. The new board is packed with features and is aimed at extreme overclockers and gaming enthusiasts.
The massive board surrounds the AMD AM4 socket with four DDR4 DIMM slots, a 12 phase Digi+ VRM, and a plethora of expansion and storage connections including two PCI-E 3.0 x16, one PCI-E 2.0 x16, three PCI-E 2.0 x1, two M.2 slots, and 8 SATA 6Gbps ports. One of the M.2 slots sits under the passive PCH heatsink and connects directly to the CPU while the other M.2 slot does not benefit from the passive heatsink and shares bandwidth with the PCI-E 2.0 lanes coming from the chipset.
The board has a massive VRM heatsink that can also be swapped out for a monoblock that can be integrated into a custom water cooling loop with ASUS partnering with Bitspower for a monoblock that will be sold separately (the board will also work with monoblocks from other manufacturers) and will include sensors to measure flow rate, temperature, and leak detection. The board also has a header that will allow you to attach those same sensors to another point in your loop with all the sensor data being available through ASUS’ Fan Xpert 4 software. There are 13 fans headers on board (16 with fan extension card) with one dedicated pump header and two groups of four fan headers that are placed closed together to make wiring up radiators a bit cleaner. The X370 ROG Crosshair VI Extreme also sports multiple RGB LED lighting zones and two headers that will allow users to extend the lighting to RGB LED strips, fans, and cases (one header is for addressable LEDs and the other is for standard LED strips up to 3A). The on board lighting zones include the IO and VRM cooler, the two SafeSlot (metal-reinforced) PCI-E x16 slots, the chipset heatsink, and the right edge of the board. The audio jacks are also LED color coded which is actually kind of cool since it can be hard to see what colors the jacks are when the case is under a desk! Other useful features include an ROG backplate and a right angle 24-pin power connector to make cable management a bit easier. There are also the usual overclocker friendly error code display, power and reset buttons, and voltage read points for multimeters. Further, the board features a dedicated base clock generator and a “TPU” (TurboV Processing Unit) that helps manage voltage to the VRMs and controls the clock generator. The external clock generator is important when overclocking Ryzen and hitting extremely high memory frequencies.
Asus is using an Intel I211-AT Gigabit Ethernet controller for the wired networking and there is also support for Intel 8265-powered 802.11 ac Wi-Fi. Sound is handled by a SupremeFX S122 codec paired with ES9023P ESS Sabre DAC with high end capacitors and TI op-amps for a 113 dB line in (for recording) and 120 dB output.
Rear I/O is where the Extreme board is a bit wanting with:
- 2 x Antenna connectors
- 2 x USB 3.1 Gen 2
- 6 x USB 3.1 Gen 1
- 4 x USB 2.0
- 5 x Gold plated 3.5mm jacks
- 1 x S/PDIF (Optical)
- 2 x Clear CMOS and BIOS Flashback buttons
On one hand, I am not sure what else they could have included (Thunderbolt is really the only missing thing and not strictly needed), but it does look a bit barren even compared to the Crosshair VI Hero.
Asus’ flagship AMD AM4 motherboard will be available in early August with an MSRP of $349.
I am interested to see if the X370 ROG Crosshair VI Extreme really does up the ante especially in the overclocking department versus the ROG Crosshair VI Hero which seems to be a popular choice for overclockers aiming to break records. I am looking forward to reviews to see whether the $100 premium is worth it (the Crosshair VI Hero is $245 or $270 with AC Wi-Fi).
Personally, I think I would rather go with a cheaper motherboard and better graphics card or SSD, but for those not on a budget I can see them opting for the board with all the bells and whistles (and RGB)!

Tagged: x299, trident z, samsung 8Gb, overclocking, G.Skill, ddr4
G.Skill recently announced new DDR4 memory kits for the Intel X299 HEDT platform. The new kits include a dual channel DDR4 4400 MHz kit for Kaby Lake X and a quad channel DDR4 4200 MHz kit for Skylake X. The dual channel kit is available under the company’s Trident Z RGB and Trident Z Black brands depending on whether you want RGB lighting or simple black heatspreaders. The quad channel DDR4-4200 kit is only available in non-RGB Trident Z modules.
According to G.Skill, all of the new memory kits use Samsung 8Gb dies and feature CAS latencies of 19-19-19-39. The quad channel 4200 MHz DDR4 modules need 1.40V to hit those specifications, and while it is not yet known what the higher clocked dual channel DDR4 4400 MHz kits need to hit CL19 timings I would presume they need a bit more.
The new kits will be available in an 8GB x 2 (16GB) 4400 MHz kit and up to 64 GB (8GB x 8) 4200 MHz kits. Pricing has not yet been announced, but the new RAM kits should be available soon. While Intel processors do not get as much of a boost from increased memory speeds as AMD’s APUs and Ryzen CPUs do, there are still noticeable gains to be had with faster memory though gamers should still prioritize graphics cards and processors over memory when picking parts for a budget build.
Note that since these kits are using Samsung 8Gb ICs, they also have a good chance of working with Ryzen, but check with your motherboard manufacturer and reviews before ponying up the cash.
