core 0 and 1 failures = lanes 0,2 adjustment
core 2 and 3 failures = lanes 1,3 adjustment
Does that sound about right?
+rep for the help btw.. thanks for being so helpful.

EDIT - here's a screenie of my system ~19 hours stable.. obviously working on voltage control

So I tried setting the voltage lower, and setting the GTLREF lanes to +0mv instead of auto.. all of a sudden my system is stable at 3.825GHz with much less voltage. Thanks for the advice. Now aiming for 4GHz, but it's getting tough.

Keep me informed....

Im trying to decide between a Q9550 or just looking into new cards.....

I was pretty much thinking the 8.5 multi being the breaking point for it...

I havent seen many Q's past 450 FSB on the 750i FTW

Lol is 1.432 volt not too much?!

Eh that max number is not really valid.. that's what Intel tells you in order to stop you from overclocking...

However I played around with it last night and my chip is now stable at 3.825GHz at 450x8.5 with only 1.344 v in CPU-Z. Setting the GTLRef lanes to +0mv from auto really helped stabilize the system.. no idea why though.

Hey the thing with the 750i FTW is it has terrible amounts of vdrop! So most people end up turning the voltage way way high in order to get the same OC. This board is decent, and fairly cheap now, but you have to be willing to fiddle with it.. you can't just rely on pure voltage to make things happen. My OC is now just as stable with 1.4v in bios as it was with 1.5v in Bios... simply because i made a couple of minor adjustments.

If you want a cheap SLI ready board that will OC decently, then I would go for it. I've seen guys with 4 GHz quads on this board, and I'm pretty close.

Just curious.. can anyone get over 450FSB on this board?? Seems pretty impossible on a Quad at least.

I'm trying to get a similar clock on the 750i ftw and q9550, would you post all of your settings and voltages (fsb, vcore, spp, mcp, mcp<->spp, gtlref's you said all +0) to get 450*8.5. I plan on running the ram at 1:1 synced at 900mhz (ocz reapers 1066).

thanks!


the q9550 I have is c1 stepping, I'll let you know if it tests out in the same config and then see if i can push the fsb above 1800.
