Due to the use of dry ice for these tests the temps were limited to a maximum of -60C in the Kingpincooling Venom 6.66 that is actually meant for LN2. I will be retesting this setup with LN2 as soon as my account is set up with my new supplier. I will then make an update posting with my new scores and findings.
With all cores enabled, the highest clock speed under dry ice that we managed to record was 5598.69 MHz at a voltage of 1.6V.
Disabling all but one core to see how far things could be pushed, we managed to get the core clock speed up to 5798.65 MHz at a voltage of 1.698V.
Here we can see Cinebench R15 @ 5098.81Mhz giving us a CPU score of 1031 cb.
Running PiFast @ 5,498.72MHz gave us a time of 12sec 30ms.
Moving onto Super Pi 1M @ 5,698.67MHz we see a great result of 6sec 381ms.
Sticking with Super Pi 32M @ 5,698.67MHz gives us a time of 5min 45sec 775ms.
Finally, you can find our Intel XTU score @ 5,300MHz of 1247 marks on HWBOT.
