HWBOT Articles

From high-end Intel i7 processors, to legacy hardware and ARM based System-on-Chips, the Challenger Division is the place where every overclocker can find a hardware segment they can call home. Running throughout the year and comprising of three two-month rounds, Challenger Division 2015 offers seven distinct divisions, each focused on a specific hardware platform.

At the core of the OC-ESPORTS concept is the idea of having an OC season, and as such only submissions made during contest time are valid in the Challenger Division. This year’s Challenger Division kicked off with Round 1, running from February 1st until March 31st. The idea is to promote the potential inclusiveness of overclocking as an Esport with a season-long, extreme and competitive OC contest that allows you to compete regardless of your ability to purchase high-end hardware. Whatever your budget, you can find an arena in which you can compete, excel and perhaps even dominate to become a Division Champion.

GPUPI 2.1 Released: 64bit and Legacy, Support for Win8, Saving Datafile

Two weeks ago we launched the new GPUPI benchmark in cooperation with The new benchmark features both CPU and GPU benchmark tests and resembles the good old SuperPI interface. The stream of new submissions followed suit and based on the feedback from the community, a new version was released three days ago.

The most important changes are of course the introduction of a 64bit and legacy version for respectively optimal performance and compatibility with older hardware configurations. We are also very pleased that GPUPI V2.1 now supports Windows 8 and up as it detects the timer used for the benchmark time-stamp. Lastly, it is now possible to save your benchmark result in a datafile and upload it later. In particular the 64bit version, in combination with Intel's latest drivers, will result in a significant performance boost. This is the reason why some community members hinted that the older version of GPUPI had better performance; an experimental v1.2 64bit beta was available.

Because the datafile offers superior security compared to a screenshot, a datafile will be MANDATORY from May 3, 2015 forward. If you have scores with GPUPI V2.0 with just a screenshot as validation proof, please submit them before this date. After May 3, no scores without the datafile will be accepted for submission. From May 3, 2015, GPUPI V2.1 will be the ONLY allowed version for submissions.

Downloads: GPUPI 2.1 (1.06 MB, CRC-32: 4E8FC28F) | GPUPI 2.1 - Legacy Version (Windows XP, GeForce 200 series, 590 KB, CRC-32: F0A26E51)

For more information regarding GPUPI V2.1, check out the following links:

  • GPUPI - SuperPI on the GPU Forum Thread: click
  • GPUPI 2.1 Announcement at click
  • GPUPI: International support thread at click

You can find the full changelog below


  • 64 bit version to allow 64 bit hardware and drivers to use their full potential (GPUPI_x64.exe).
  • New time measurement using QPC if available and RTC as fallback for Windows 7/XP.
  • HWBOT submissions can now be saved as data file to disk and submitted later.
  • HWBOT submission supports skipping of CPU/GPU (for detection errors) and allows erroneous submissions to be updated manually when needed. Therefor the pure manual submission of scores will be disabled again, because it's the most secure way.
  • Legacy version compiled with Visual Studio 2012 (Update 4) and CUDA toolkit 6.0. It has CUDA and OpenCL support for Windows XP and allows GeForce 200 series cards (CUDA capability 1.3) to run the benchmark. The Legacy version is slower than the default executables and should only be used if necessary!
  • Detects ~50 AMD graphics cards now (about 30 more than 2.0) including R9 300 family.
  • Automatic window resizing after a benchmark run to avoid cutting off statistics or the result. It's only done if necessary and helps especially multi GPU results.
  • Adds a watermark to invalid results to easily distinguish them from successful runs.
  • Ctrl+A now selects all text in output window.
  • Added support for UNICODE file paths for logging and configuration.
  • Hardware detection fixed for Xeon CPUs, AMD HD 7770/7750/7730 and Core 2 Duos/Quads.
  • Reduced the executable file sizes by removing unnecessary source code and several dependencies


SuperPI Low-Clock Challenge Overview Table Update (Apr 24)

Today we have a look at the SuperPI 32M low-clock challenge threads in our forum and make a list of the most efficient overclocks for various CPU architectures. We update the table once more in this news article. There are a couple of new leaders in the specific categories such as Dancop for Haswell and Bullant in the Sandy Bridge. We have also included Bulldozer and Llano categories.

Congratulations to all the leaders in their specific category. Top stuff!

[PR] G.SKILL Announces the World's Fastest DDR4 128GB (16GBx8) Memory Kit at 2800MHz!

Taipei, Taiwan (23 April 2015) – G.SKILL International Enterprises Co., Ltd., the world’s leading manufacturer of extreme performance memory and solid state storage, is thrilled to announce the world’s first DDR4 128GB(16GBx8) 2800MHz CL16-16-16 -36 1.35V memory kit based on the newest 16GB capacity DDR4 consumer-class memory modules. These high capacity memory modules are manufactured with new 8Gb ICs produced on the latest 20nm fabrication process, which takes performance to a whole new level, by Samsung Electronics.

While 16GB capacity have been available for server memory in the past, support and design for such large capacity memory modules are now paving its way to consumer memory modules, suitable for workstation level workloads where high capacity memory is vital. These new G.SKILL Ripjaws 4 series high capacity memory kits are capable of running in quad-channel at a grand total of 128GB, and have already been validated on the latest ASUS X99 Rampage V Extreme motherboard with Intel Haswell-E processors. A stress-testing screenshot of the newly released memory kit with 16GB DDR4 modules can be found below.

MSI OC Academy Cambridge Report by

Ben from attended the MSI OC Academy in Cambridge, United Kingdom last week and wrote a nice report on it. There are plenty of pictures inside for those who fear a long spun out article!

Read Full Article

When all is said and done, the event was good fun! There was plenty of overclocking going on from experienced users and they were always nice enough to answer questions that any of the new comers may have, or, even lend a hand if need be. There was plenty of hardware to go around and anyone that wanted to was able to get their hands on a bit of LN2 fun.

If you are interested in overclocking or just PC hardware in general these events are a great place to get acquainted with it all and have some fun with a great group of people. Aside from the new comers, everyone is quite knowledgeable and more than happy to answer a few questions on most things to do with LN2 and overclocking in general.

There was a couple of world records broken via Roman and Ian, but their efforts did seem to kill quite a few graphics cards which led to Mr Der8uer reaching for his soldering iron on a regular basis. Our fellow overclocking guru gavbon also had a great event; he lost both heats by 1 point and in the 2nd, his opponent was the 2nd highest ranked overclocker in the UK. A mightily impressive achievement and a lot of respect between fellow competitors and, of course, the community as a whole.

If you are interested in learning more or maybe even being able to attend the next event, make sure to follow MSI UK and Team Great Britain Over-clockers so you will know when the next event will be held. Alternatively you can let us know via social media as gavbon (our boss) is a huge advocate of the overclocking community and wants to help it grow; huge shout-out to Dagmar (HiVizMan) for being the glue that held the weekend together!

XTU 5.1.2 Now Available For Download; Updated Security Keys, Older Versions Valid For Only 3 Months

On April 1, 2015, Intel released a new version of the Intel eXtreme Tuning Utility. The new version, v5.1.2, includes a couple of new features. First and foremost, based on the feedback from our very own El Genieben Intel improved the security of the XTU profiles. This optimization includes updating the security keys of the XTU profiles. The transition from the old to the new keys is three (3) months. From July 1, no XTU versions older than 5.1.2 can be used to make submissions.

In addition to the new security keys, Intel also included a telemetry functionality allowing to gathering information on XTU usage to improve the experience. The telemetry can always be disabled in the settings menu and is not required to be enabled for making valid submissions. Lastly, there's additional support for upcoming platforms.

You can download the XTU 5.1.2 here. You can find the release notes here.
