the i7 build

Got to work on HELLFIRE thursday night.

Setup: EX58-UD3R, i7 920 D0, 3x1GB GSkill DDR3-1333, Akasa Nero

The Akasa Nero comes with a piddly 12cm Akasa fan:

So I strapped my 200CFM Delta fan on it:

Went to 3.7Ghz/185BLCK without any issues - just upping BCLK. RAM was set on auto SPD timings, but ran at 1480Mhz.

For 190BCLK I put the RAM down a ratio, also lowered the voltages on the core.

Had to up some voltages for 195BCLK, but w32 under 7 seconds:

All the time I was thinking temperatures. Using Real Temp 3.0, they were hitting 74-ish.

Going to 200BCLK, and the motherboard kept rebooting, no matter what settings I put it to. Until I put a few setting on Auto on the motherboard, then it booted first time. Went back to the mobo with those settings, put them in, and it failed to boot. WTF?

For 205BCLK, upped Vcore to 1.2875V:

Managed to get the timings for RAM down to 7-6-7-15 at 1230Mhz, but not done any benchmarks with it.

Using the EasyTune, put it up to 210BClk, got a cpuz:

But running any wPrime caused it to hang. Choosing 210 in the BIOS and it failed to start. I don't really want it getting hotter; I mean 75ÂșC is a bit toasty for me. Might clock back to 3.7 for day to day work.

Kept track of wPrime scores and settings:

EDIT: Since I wrote this, I went on the BenchTec/SCAN performance day in Bolton - got some good tips and I'll be redoing the overclock.
