Overclocking Results

I’ve continued the trend of limited voltage overclocking for this overclocking segment. Like past tests I have manually set the voltages to 1.35vCPU, 1.30VTT, 1.8vPLL, 1.65vDIMM with the CPU
running the 9x multiplier, 18x QPI multiplier, and the 2:10 memory
divider. Using the multi-meter probe on ports on the P55-GD85 I set the voltages in
BIOS that most closely hit the desired voltages while under load. For the baseclock tests I ran the CPU with the above setting and snapped a picture of the base clock that made it through a Super Pi 1M and 32M run. Lastly, for the 24/7 stability test I bumped the multiplier up to 21x and pushed the CPU to the limit.

Given the baseclock limits of this CPU (around 217MHz on air), this is quite decent. In previous testing with the P55-GD65 I was able to hit 214.5MHz baseclock; perhaps the stars were properly aligned on that day.

Just like the P55-GD65 I reviewed 2 months ago the P55-GD85 wasn’t able to maintain that high baseclock for Super Pi 32M. 210.5MHz was the limit; once again it was 1 MHz lower than the P55-GD65 results from December.

4083MHz through 5 loops Intel Burn Test is impressive and once again 1 MHz baseclock less than what was achieved with the P55-GD65. Maybe my CPU is degrading or maybe I had a slightly better heatsink mount on that previous session. Either way 4083MHz on this CPU with 1.35v is par for the course which is great news.
