PAX Australia 2016 Panel "Pushing Limits: Going Beyond 8 GHz"HWBOT
The simplest and easiest way to understand a very general concept of overclocking is that of increasing the processor frequency to improve performance. The lucky few among you may have a system that runs at 5GHz or above. Extreme overclockers however, go well beyond that limit.
On November 4th 2016, Australian Overclockers held a public panel at the PAX AUS 2016 event at the Melbourne Convention center. Hosted at the Wombat Theater the panel will discuss the difficulties encountered when overclocking beyond 8GHz and will include an impressive live demo of an LN2 cooled overclocked system running at 8GHz!

It’s that time of the year again when overclocking teams on HWBOT start eyeing the HWBOT Team Cup, the ultimate prize in team-oriented overlocking. It’s a contest that pits dozens of teams of overclockers against each other with a total of thirty stages that covers virtually every hardware category imaginable.
Running throughout the months of July, August and September, the HWBOT Team Cup is surely the truest test of competitive team overclocking, requiring the broadest possible array of skill sets with overlockers invited to bench on everything from the latest Skylake and Haswell-E platforms to legacy Intel and AMD platforms including stages devoted to DDR2 and DDR tweaking as well as two newly devised ‘Dogpile’ stages that require you to make as many submission as possible on as many CPUs as possible.
This year’s contest involves five separate challenges or sub-competitions as we refer to them, each with an historical epoch in mind. Contest categories include Current Generation, Modern, Legacy, Vintage and Dogpile. Let’s look at the stages in more detail regarding specific hardware limitations and benchmarks.
GPUPI calculates the mathematical constant Pi in parallel by using the BPP formula and optimizing it for OpenCL capable devices like graphics cards and main processors. It's implemented with C++, STL and pure Win32 to avoid unnecessary dependencies. The result of the benchmark are exactly nine digits of pi in hexadecimal. So if you're calculating pi in 1B (1 billion) it will not output all digits like available serial calculations of Pi, but display only the nine digits after the billionth hexadecimal digit. This limitation is due to the nature of parallel implementations and the used Pi formula.

New Overclocking Capabilities†
Feature Details
Per Core Overclocking
Ability to OC Turbo Ratio of specific individual processor Cores.
Creates the opportunity to unleash more headroom on certain cores.
AVX Ratio Offset
Enables overclocked diversity between non-AVX2 and AVX2 Core
frequency levels. Can be utilized to enable higher frequencies for
non-AVX2 enabled applications by allowing AVX2 instructions to run
at lower frequencies.
VccU Voltage Control
Voltage control used to extract more frequency from Ring
overclocking. This is useful particularly in extreme (LN2) overclocking
scenarios.
†Overclocking results not guaranteed and subject to change.13
VccU Voltage Control
VccU
• Exposing new voltage knob to help

OC ratio for each individual core
‒ Based on manufacturing variation,
some cores can run faster than
others
• Some reliability improvements possible
by targeting cores with lower initial
voltage
Per Core Overclocking!
• As an example, some of the cores may be capable of
200-400MHz additional OC headroom†
