Extreme Overclocking of Skylake (7.02566 GHz)

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 Releases BIOS to Disable Non-K Skylake Overclocking

Subject: Processors | February 5, 2016 - 11:44 AM |
Tagged: Intel, Skylake, overclocking, cpu, Non-K, BCLK, bios, SKY OC, asrock, Z170

ASRock's latest batch of motherboard BIOS updates remove the SKY OS function, which permitted overclocking of non-K Intel processors via BCLK (baseclock).

20151215-8.jpg

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.

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.

EVGA Z170 Motherboards to Support BCLK Overclocking Non-K CPUs

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:

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.

Overclocking Locked Intel Skylake CPUs Possible - i3 6100 Benchmarked

Subject: Processors | December 11, 2015 - 02:08 PM |
Tagged: Skylake, overclocking, Intel, Core i3-6100, bios, BCLK, asrock

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.

"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.

AMD R9 Fury X Voltage and HBM Unlocked with Sapphire TriXX 5.2.1

Subject: Graphics Cards | November 18, 2015 - 01:22 PM |
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.

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..."

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.

AMD Radeon R9 Fury Unlocked as Fury X, Overclocked to 1 GHz HBM

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.

fury_ln2_01.JPG

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.

fury_ln2_02.jpg

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.

fury_ln2_03.JPG

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.

Overclock any NVIDIA GPU on Desktop and Mobile with a New Utility

Subject: Graphics Cards | August 10, 2015 - 06:14 PM |
Tagged: overclocking, overclock, open source, nvidia, MSI Afterburner, API

An author called "2PKAQWTUQM2Q7DJG" (likely not a real name) has published a fascinating little article today on his/her Wordpress blog entitled, "Overclocking Tools for NVIDIA GPUs Suck. I Made My Own". What it contains is a full account of the process of creating an overclocking tool beyond the constraints of common utilities such as MSI Afterburner.

By probing MSI's OC utility using Ollydbg (an x86 "assembler level analysing debugger") the author was able to track down how Afterburner was working.

nvapiload.png

“nvapi.dll” definitely gets loaded here using LoadLibrary/GetModuleHandle. We’re on the right track. Now where exactly is that lib used? ... That’s simple, with the program running and the realtime graph disabled (it polls NvAPI constantly adding noise to the mass of API calls). we place a memory breakpoint on the .Text memory segment of the NVapi.dll inside MSI Afterburner’s process... Then we set the sliders in the MSI tool to get some negligible GPU underclock and hit the “apply” button. It breaks inside NvAPI… magic!

After further explaining the process and his/her source code for an overclocking utility, the user goes on to show the finished product in the form of a command line utility.

There is a link to the finished version of this utility at the end of the article, as well as the entire process with all source code. It makes for an interesting read (even for the painfully inept at programming, such as myself), and the provided link to download this mysterious overclocking utility (disguised as a JPG image file, no less) makes it both tempting and a little dubious. Does this really allow overclocking any NVIDIA GPU, including mobile? What could be the harm in trying?? In all seriousness however since some of what was seemingly uncovered in the article is no doubt proprietary, how long will this information be available?

It would probably be wise to follow the link to the Wordpress page ASAP!

Overclocking the R9 390X

Now that [H]ard|OCP has had more time to spend with the new R9 390X they have managed to find the overclocks that they are most comfortable running on the card they used to test.  They used MSI Afterburner 4.1.1 and first overclocked the card without changing voltages at all, which netted them 1150MHz core and 6.6GHz effective on the RAM.  From there they started to raise to Core Voltage, eventually settling on +50 as settings higher than that resulted in lower maximum observed voltages due to the TDP being reached and the card throttling back.  With that voltage setting they could get the card to run at 1180MHz, with the memory speed remaining at 6.6GHz as it is not effected by the core voltage settings, with the fan speed set 80% they saw a consistent 67C GPU temperature.  How much impact did that have on performance and could it push the card's performance beyond an overclocked GTX 980?  Read the full review to find out in detail.
