WR X6800 at 5717MHz!

CPU-Z validation


After whole weekend of playing with LN2 a couple of CPUs and mobos, I kinda unexpectedly achieve highest frequency with X6800. It was done on P5W64 WS Pro at 1.92v and pot temp at -155°C.
This CPU has amazing cold tolerance, on 1st day it could run and boot at -158 pot temperature, with perfect contact, temp in bios was -125°C and we all know that this mobo shows temp +15° in comparison to other mobos.
Sadly, but true, on the sesion, when WR was achieved, CPU couldn't calculate Spi 1M at 5300MHz, no mater what. I tried suicide screen when I gave up on SPi and I was just shocked, that's why i named thist CPU a Mutant CPU.



So the best Spi 1M run with this CPU was done a day before, at 5345 and pathetic 411 FSB and ram at 4-4-4-12 822MHz. At that time I was just trying CPU, so I didn't bother to do a proper screen, optimized run. I had to stop the sesion, cause mobo won't go over 420FSB (FFS) and 14 multi didn't work. I was using 304 bios, 402 fixed multi bug, and FSB went up when i switched PCI-E graphic card for PCI. And very saddly, after that I couldn't do another Spi 1M over 5300MHz, so that is my best Spi 1M run .


CPU-Z Validation

Also, I have tried E6700 on P5B Dlx, nothing special, i was able to do a cpuz verification at 5302Mhz. I will try the CPU on Commando next time, hope for the WR.
