Amazing what a water cooling can do for max stable bclk too. On air 228 bclk was max for 32M pi, but on H20 straight boot from bios 32M done at 230blck with ease!

229bclk boot from bios

230bclk boot from bios

231bclk 32M Passed

232bclk 1M

setfsb bump from 230bclk to 233bclk

Nice eva!

After all the cpu block mounts I have been through on i7 testing blocks, I still cannot get used to the "normal" core temps. In time I guess.

233bclk

, great going George , my RIIE cannot get closed to that. Congrats mate. Keep pushing

Great numbers Eva ... who says we have to dump these early i7's and go get DO's

Thanks skinnee ... yeah my solution is to not look at the core temps

thanks.. hopefully will pick up some D0 920s next week and have a good memory controller on them!

Thanks

Pushing some suicide everest runs with memory clocked to the max to see what kind of everest numbers I get

Best I can do for now

4/28 beta bios and new max bclk validation @235bclk with 6-7-6-20 timings!

so close to sub 9min 32M pi at <3900Mhz!

sub 4000Mhz 32M

Max BCLK

Super Pi 1M to 32M

1M = 9.328s
2M = 21.000s
4M = 46.422s
8M = 1min 42.750s
16M = 3min 45.782s
32M = 8min 11.859s

Starting to hit probably thermal limits of my i7 920 3836A756 on H20 cooling as 32M Pi seems to be topping out around 4680mhz with HT disabled. Only managed to shave ~1 second off my best 32M pi time with i7 920.

cracking review again george, you are the master of thorough testing, for my forthcoming i7 build i have a thermochill pa 120.3 and a pa160.1 already installed , which i was going to use to cool the cpu only , what i'm asking is i also have a pa120.2 which i could plumb in as well, is there any point or is the dissapated heat already covered with the 2 rads i already have in
