Early this week at the Intel Developer Forum in San Francisco, California G.Skill showed off new low latency DDR4 memory modules for desktop and notebooks. The company launched two Trident series DDR4 3333 MHz kits and one Ripjaws branded DDR4 3333 MHz SO-DIMM. While these speeds are not close to the fastest we have seen from them, these modules offer much tighter timings. All of the new memory modules use Samsung 8Gb chips and will be available soon.
On the desktop side of things, G.Skill demonstrated a 128GB (8x16GB) DDR4-3333 kit with CAS latencies of 14-14-14-34 running on a Asus ROG Rampage V Edition 10 motherboard with an Intel Core i7 6800K processor. They also showed a 64GB (8x8GB) kit clocked at 3333 MHz with timings of 13-13-13-33 running on a system with the same i7 6800K and Asus X99 Deluxe II motherboard.

In addition to the desktop DIMMs, G.Skill showed a 32GB Ripjaws kit (2x16GB) clocked at 3333 MHz running on an Intel Skull Canyon NUC. The SO-DIMM had timings of 16-18-18-43 and ran at 1.35V.
Nowadays lower latency is not quite as important as it once was, but there is still a slight performance advantage to be had tighter timings and pure clockspeed is not the only important RAM metric. Overclocking can get you lower CAS latencies (sometimes at the cost of more voltage), but if you are not into that tedious process and are buying RAM anyway you might as well go for the modules with the lowest latencies out of the box at the clockspeeds you are looking for. I am not sure how popular RAM overclocking is these days outside of benchmark runs and extreme overclockers though to be honest.
Overclocking Innovation session at IDF 2016.
With regards to extreme overclocking, there was reportedly an "Overclocking Innovation" event at IDF where G.Skill and Asus overclocker Elmor achieved a new CPU overclocking record of 5,731.78 MHz on the i7 6950X running on a system with G.Skill memory and Asus motherboard. The company's DDR4 record of 5,189.2 MHz was not beaten at the event, G.Skill notes in its press release (heh).
Are RAM timings important to you when looking for memory? What are your thoughts on the ever increasing clocks of new DDR4 kits with how overclocking works on the newer processors/motherboards?

Overclocking the new Pascal GPUs can be accomplished with the EVGA Precision X tool as it allows you to bump up the power, temperature target and fan speed as well as the frequencies for the GPU and memory easily and effectively. [H]ard|OCP set out to push the 1070 as far as it would go with this software in a recent review. The power target can only be increased to 112%, which they implemented along with setting the fan to 100% as this is about the maximum performance, not about peace and quiet. After quite a bit of testing they settled on 2062MHz GPU and 4252MHz RAM clocks as the highest stable frequency this particular card could manage. The results show a card which leaves the TITAN X in the dirt and this card does not even have a custom cooler; we anxiously await the non-Founders Edition releases to see what they can accomplish.
"In our overclocking review of the NVIDIA GeForce GTX 1070 Founders Edition we will see how far we can overclock the GPU and memory and then compare performance with GeForce GTX TITAN X and GeForce GTX 980 Ti. How high will she go? Can the $449 GTX 1070 outperform a $1000 GTX TITAN X? The answer is exciting."

The guys over at the Tech Report spotted a rather shiny product coming out soon from EKWB. The company is adding a nickel plated memory heat-spreader kit can be used to replace your existing heatspreaders and hook into a RAM waterblock like EKWB's own Monarch X2 to allow you to liquid cool your memory and add it to your custom cooling loop.
These new modules are similar to the existing black modules, but have a nickel plated finish that is particularly shiny (see the photo below). Each kit includes the parts to replace the heatspreaders on two memory modules. Thermal pads are used to facilitate heat transfer from the memory chips to the CNC'ed aluminum heatsinks.
Users can then screw a memory waterblock (EKWB specifies the Monarch X2 Acetel/Nickel) to the top of the replaced memory heat-spreaders. Heat is then transferred from the heatsinks to the block and finally to the water loop.
The new Monarch modules are available now for $34.99. The Monarch X2 waterblock adapter is a further $38.99 if you want to water cool the DRAM. Note that the existing black anodized heatsinks are a bit cheaper at $29.99.
The heatsinks certainly look nice, and while I can see reasons to liquid cool them for aesthetics or to play around with extreme overclocking water cooling your memory using them will get expensive in short order considering you need to buy both kits for every two memory DIMMs (I hope you don't have X99 with all slots populated heh).
If you really want to cool all the things and add a bit of 'bling' to your system look no further!

Tagged: Skylake, overclocking, asrock, Intel, gskill
I recently came across a post at PC Gamer that looked at the extreme overclocking leaderboard of the Skylake-based Intel Core i7-6700K. Obviously, these competitions will probably never end as long as higher numbers are possible on parts that are interesting for one reason or another. Skylake is the new chip on the liquid nitrogen block. It cannot reach frequencies as high as its predecessors, but teams still compete to get as high as possible on that specific SKU.
The current world record for a single-threaded Intel Core i7-6700K is 7.02566 GHz, which is achieved with a voltage of 4.032V. For comparison, the i7-6700K is typically around 1.3V at load. This record was apparently set about a month ago, on January 11th.
This is obviously a huge increase, about three-fold more voltage for the extra 3 GHz. For comparison, the current world record over all known CPUs is the AMD FX-8370 with a clock of 8.72278 GHz. Many Pentium 4-era processors make up the top 15 places too, as those parts were designed for high clock rates with relatively low IPC.
The rest of the system used G.SKILL Ripjaws 4 DDR4 RAM, an ASRock Z170M OC Formula motherboard, and an Antec 1300W power supply. It used an NVIDIA GeForce GT 630 GPU, which offloaded graphics from the integrated chip, but otherwise interfered as little as possible. They also used Windows XP, because why not I guess? I assume that it does the least amount of work to boot, allowing a quicker verification, but that is only a guess.

ASRock's latest batch of motherboard BIOS updates remove the SKY OS function, which permitted overclocking of non-K Intel processors via BCLK (baseclock).
The news comes amid speculation that Intel had pressured motherboard vendors to remove such functionality. Intel's unlocked K parts (i5-6600K, i7-6700K) will once again be the only options for Skylake overclocking on Z170 on ASRock boards (assuming prior BIOS versions are no longer available), and with no Pentium G3258 this generation Intel is no longer a budget friendly option for enthusiasts looking to push their CPU past factory specs.
(Image credit: Hexus.net)
It sounds like now would be a good time to archive that SKY OS enabled BIOS update file if you've downloaded it - or simply refrain from this BIOS update. What remains to be seen of course is whether other vendors will follow suit and disable BCLK overclocking of non-K processors. This had become a popular feature on a number of Z170 motherboards on the market, but ASRock may have been in too weak a position to battle Intel on this issue.

An upcoming BIOS update for EVGA Z170 motherboards to allow BCLK overclocking on non-K Intel processors.
The news came from EVGA Product Manager Jacob Freeman via Twitter this afternoon:
New Z170 BIOS for BCLK OC'ing on non K CPU's coming right up
— Jacob Freeman (@EVGA_JacobF) January 15, 2016
Update: The new BIOS 1.07 enabling non-K BLCK OC is now available from EVGA.
We have been following the story of BCLK overclocking of locked Skylake CPUs since early last month, when Techspot published benchmarks from an Intel Core i3-6100 clocked at 4.70 GHz - thanks to a pre-release ASRock BIOS. The BIOS has since been released, and other vendors are updating their Z170 motherboards to support these locked processors as well, the latest being EVGA.
It remains to be seen if Intel will have anything to say about their cheaper "locked" processors becoming more attractive to potential overclockers, as the unlocked K parts have provided a nice profit margin for the company. So far, board partners are moving forward seemingly unimpeded with the updates to remove the overclocking limitations, and that's great news for enthusiasts.

The days of Intel overclocking being limited to their more expensive unlocked parts appear to be over, as TechSpot has posted benchmarks from an overclocked Intel Core i3-6100 using a new (pre-release) BIOS update from ASRock.
Image credit: TechSpot
"In overclocking circles it was recently noted that BCLK (base clock) overclocking might become a possibility in Skylake processors. Last night Asrock contacted us with an updated BIOS that enabled this. We jumped at the opportunity and have already tested and benched a Core i3-6100 Skylake CPU with a 1GHz overclock (4.7GHz) on air cooling."
The 1.0 GHz overclock was achieved with a 127 MHz base clock on the i3 processor, with a vcore of ~1.36v. Apparently the ASRock motherboard requires the processor's graphics portion to be disabled for overclocking with this method, and TechSpot used an NVIDIA GTX 960 for test system. The results were impressive, as you might imagine.
The following is a small sampling of the benchmark results available from the sourced TechSpot article:

The overclocked i3-6100 was able to come very close to the multi-threaded performance of the stock AMD FX-8320E (8-core) processor in Cinebench, with double the per-thread performance. Results from their Handbrake encode test were even better, with the overclocked i3-6100 essentially matching the performance of the Core i5-4430 processor tested.
Gaming was underwhelming, with very similar performance from the GTX 960 from all CPUs at the settings tested.

So what did the article say about this new overclocking-friendly BIOS availability? "We are told this updated BIOS for their Z170 motherboards will be available to owners very soon." It will be interesting to see if other vendors offer the same, as there are results out there using a SuperMicro board as well.

Tagged: Sapphire TriXX, R9 Fury X, overclocking, hbm, amd
The new version (5.2.1) of Sapphire's TriXX overclocking utility has been released, and it finally unlocks voltage and HBM overclocking for AMD's R9 Fury X.
(Image credit: Sapphire)
Previously the voltage of the R9 Fury X core was not adjustable, leaving what would seem to be quite a bit of untapped headroom for the cards which shipped with a powerful liquid-cooling solution rated for 500 watts of thermal dissipation. This should allow for much better results than what Ryan was able to achieve when he attempted overclocking for our review of the R9 Fury X in June (without the benefit of voltage adjustments):
"My net result: a clock speed of 1155 MHz rather than 1050 MHz, an increase of 10%. That's a decent overclock for a first attempt with a brand new card and new architecture, but from the way that AMD had built up the "500 watt cooler" and the "375 watts available power" from the dual 8-pin power connectors, I was honestly expecting quite a bit more. Hopefully we'll see some community adjustments, like voltage modifications, that we can mess around with later..."

- You can download the new TriXX v5.2.1 software from the product page at Sapphire here.
Will TriXX v5.2.1 unleash the full potential of the Fury X? We will have to wait for some overclocked benchmark numbers, but having the ability can only be a good thing for enthusiasts.

Tagged: STRIX R9 Fury, Radeon R9 Fury, overclocking, oc, LN2, hbm, fury x, asus, amd
What happens when you unlock an AMD Fury to have the Compute Units of a Fury X, and then overclock the snot out of it using LN2? User Xtreme Addict in the HWBot forums has created a comprehensive guide to do just this, and the results are incredible.
Not for the faint of heart (image credit: Xtreme Addict)
"The steps include unlocking the Compute Units to enable Fury X grade performance, enabling the hotwire soldering pads, a 0.95v Rail mod, and of course the trimpot/hotwire VGPU, VMEM, VPLL (VDDCI) mods.
The result? A GPU frequency of 1450 MHz and HBM frequency of 1000 MHz. For the HBM that's a 100% overclock."
Beginning with a stock ASUS R9 Fury STRIX card Xtreme Addict performed some surgery to fully unlock the voltage, and unlocked the Compute Units using a tool from this Overclock.net thread.
The results? Staggering. HBM at 1000 MHz is double the rate of the stock Fury X, and a GPU core of 1450 MHz is a 400 MHz increase. So what kind of performance did this heavily overclocked card achieve?
"The performance goes up from 6237 points at default to 6756 after unlocking the CUs, then 8121 points after overclock on air cooling, to eventually end up at 9634 points when fully unleashed with liquid nitrogen."
Apparently they were able to push the card even further, ending up with a whopping 10033 score in 3DMark Fire Strike Extreme.
While this method is far too extreme for 99% of enthusiasts, the idea of unlocking a retail Fury to the level of a Fury X through software/BIOS mods is much more accessible, as is the possibility of reaching much higher clocks through advanced cooling methods.
Unfortunately, if reading through this makes you want to run out and grab one of these STRIX cards availability is still limited. Hopefully supply catches up to demand in the near future.
A quick look at stock status on Newegg for the featured R9 Fury card
