HWBOT Articles

Today we are in for a real treat as the Overclocker in Focus series gets talking to a rising star from Indonesia, the one and only Coldest. In recent years Coldest has quickly risen up the HWBOT hierarchy, becoming an important member of the Indonesia team in the process. Welcome to a fireside chat with a true OC evangelist, competitor and winner. Welcome to our friend Coldest.

"Why the cheap hardware can improve the growth of the community of Overclocking? We can just see the examples, just like when Intel released the Pentium anniversary… Pentium G that can overclock. We can invite overclockers in Indonesia, for amateurs to learn overclocking with a low budget with the cheap CPU and as you know also the Z87 and there are some Z97 motherboards with a cheap price also, so they can learn overclocking.

Elmor's Lab: Independent Core Overclocking for Haswell-E

Elmor has a small section on the forum reserved for his overclocking research projects. For example, there is a support thread for the EVC software. Yesterday Elmor shared a small software application to overclock the cores of your Haswell-E processor independently.

Quick re-cap: overclocking an Intel processor typically goes via the Turbo multipliers, a set of ratios unlocked on -K and -X processor SKUs. (Edit*) The Turbo frequency is configured on utilization basis, assigning a specific frequency to a certain type of load. For example on an 8-core part, if any three cores are in use they will be boosted to the configured 3-core ratio while the five idle cores stay at the base frequency.

For AMD processors the situation is a bit different as all cores can be clocked independently. That is why you will often see 8GHz+ CPU overclockers with all other cores clocked to 800MHz or lower. Having independent frequency control for each core helps you push for better benchmark results in single threaded benchmark applications as you are not restraint by the weaker cores in the CPU.

The software tool Elmor developed works in combination with TurboC Core and is currently only tested on the Rampage V Extreme motherboard. As Elmor writes: "When first started it will ask you 'Init per core mode?', entering 'y' will apply the current max ratio to each core. After that you use TurboV Core only to set your maximum possible ratio. If you want you can just set it to 80 and forget about it until next reboot. Whatever ratio you set in this software will now be applied on a per core basis."

You can find all details and download information in the forum thread. Good luck!

(EPIC) The Truth about CPU Soldering - Der8auer Tries Solder Thermal Interface on Skylake

So, sometimes people complain about the relatively weak thermal interface material on the new Intel processors. Especially compared to their HEDT counterparts, which have a solder based TIM, it seems that it's a low-balling approach to use plain thermal paste on a CPU that still costs over USD $400. Well, luckily we have Der8auer who takes the time to explain the problems with solder and even tries to solder TIM on the 6700K Skylake. This is a good read, I promise!

The gist of the article comes down to this: micro-cracks in the solder interface puts the CPU at higher risk of damage earlier in its total lifespan than conventional thermal paste does. In addition, mining the materials required for preparing the CPU for solder thermal interface (like gold and indium) is expensive and ecologically not that great. Regular ol' thermal paste may perform worse, all things considered it's a better choice especially for small sized processor dies.

Please have a look at for the full article and scientific background information. Amazing research!

SergeyR Wins Rookie Rumble #24 Again, Kos_S Wins AMD #21... Again

The 24th installment of the Rookie Rumble on OC-ESPORTS has just concluded with a distinctly ‘Ground Hog Day’ flavor to it. Ukrainian overclocker SergeyR again makes a full sweep of all three stages to claim a second consecutive Rookie Rumble title. While in terms of AMD rookie action, we also see a repeat of the previous round with Kos_S taking the AMD Rookie Rumble #21 title. Let’s look at the stages, scores and winners in a little more detail.

Secondly congrats to SergeyR for a dominant display that saw him not only claim all three stages once again, but also hit a number of scores that out-do his previous personal bests from the last round. Also congrats to and TAGG for their efforts in reaching second and third places on the podium. We should keep an eye on these two rising stars.


Congrats to all the AMD enthusiasts who took part. Especially to Kos_S who proved once again to be a worthy champion.

Futuremark Tightens RTC Validation Check Following Tecmundo and Rbuass Findings

Futuremark is improving the detection of all types of 'gaming' of their benchmark software. Two weeks ago we reported on the removal of a ton of Hall of Fame submissions due to LOD alteration and following the Rbuass' findings shared in our forum and reported by Tecmundo, Futuremark is tightening the detection of the benchmark timer. For those who are not familiar with the problem, here is a brief overview of the Windows 8 / 8.1 / 10 RTC problem.

On August 8, 2013, we published an article detailing issues concerning the use of timer in Windows 8. The use of the RTC timer impacts the veracity of benchmark results in such a way that decreasing the base clock frequency at run-time will cause a drift in timer. In short, a second no longer consists of 1000 milliseconds, but consists of 1000 milliseconds times the decrease in base clock frequency. For example, a decrease of 5% in frequency would increase the 'time in a second' by 5%. Because the system is unaware of this, the benchmark result will seem 5% better. For more information and supporting data, I suggest you to read through our original article.

In a response, Intel hot-fixed the XTU benchmark and uses the more accurate HPET since v4.2.0.8. Early September Futuremark announced a fix for the Windows 8 RTC bug though the Systeminfo service. From that moment, the HWBOT moderators accepted 3DMark benchmark submissions on the Windows 8 (8.1/10) operating system provided a supplementary verification link as proof that the RTC was not tampered with.

On November 20, Rbuass showed in a YouTube video that it's possible to validate 3DMark submissions even if the RTC had been affected. Based on data provided by Rbuass it seems that if one stayed within a 2% margin, a benchmark result would still validate correctly. As we have learned over the past couple of days, this is possible because the timer validation process Futuremark uses on their online database compares the data from the HPET and RTC timer and flags the result as invalid if the difference is too large. For competitive overclockers 2% is a large margin as even with a single GPU in Fire Strike Extreme it can easily mean a difference of a couple of hundred points. It's important to note that any RTC drift, where the OS time is not real time, means the benchmark score is NOT valid.

Christian Ney, Head of Moderating, got in touch with Futuremark to see if anything could be done about the situation. At the moment of writing, Futuremark has already tightened the margin of the RTC and HPET timer for new submissions, meaning any result with RTC drift will be invalidated. In addition, based on historical data Futuremark will also sort through the current Hall of Fame submissions and re-evaluate the validity of the scores.

As Futuremark (in)validates the top benchmark results, the HWBOT staff will proceed checking the Global rankings as well. More information to follow.

The fifth round of the 2015 Novice Nimble season has drawn to a close just a few days ago and for the first time we actually have a winner that is not Cowcotland. The French novices have finally been pipped at the post, with a US-based team edging out all competitors in the largest and most fiercely contested Novice Nimble round yet. Read on for a full appraisal of the stages, scoring and the final standings.

Just in case you are not fully conversant in the world of competitive novice-grade Overclocking, here’s a quick overview. The Novice Nimble series on OC-ESPORTS allows groups, or indeed teams of Novice-level overclockers to compete head to head. The contest requires that three team members submit scores in each of the five stages using different hardware. The average score of these submissions dictates the team’s standings on each stage.
