Today I put my new E6600 retail chip in my Intel D975XBX rev 304 motherboard. Before I had an E6600 EA (A1) in there. I did the debug mod a while back, so I could adjust Vcore on the A1.
Well, now with the retail E6600 I can set Vcore, but it stays at defualt regardless of what I set it to. Strap fsb does the same. I'm using bios 1334, but I've tried 1304 and 10xx with exatcly the same results.
Anybody have a clue? Or similar experiences?
tried power down and unplug power, configure/maintenance jumper boot to bios, save and reboot, then power down, back to normal jumper and boot ?

I have had it powered down completely, but haven't tried the maintenance jumper. It's definetely worth a try though.Originally Posted by eva2000
:/ is this a recurring issue?
I tried booting into maintenance mode as eva2000 suggested, and now at least Vcore works, so thanks mate
However the board will not boot with fsb strap @ 1333 Mhz. I can easily boot @ 1067 + 50%, and using clockgen I'm at least 3d stable @ 3.8 Ghz ~1.45V Vcore. This is with 2x x1900xt's in crossfire and 4x corsair 5400UL's @ 1:1 422 Mhz fsb cas 4-3-3-8 @ 2.2V
Yeah i had to boot into maintenance when ifirst setup my 2nd badaxe E6600 B1 rig, changing burn in % had no effect 1067fsb + 50% on reboot was 2400mhz still. Maintenance mode fixed that problem
Not sure about your 1333fsb strap issue, try with only 2x 512MB modules ? you might need more vcore maybe ? try 1.5v vcore

Alright good.
What are your MB volts at 1067 +50%?
my rig on water does 1067 + 50% at 1.371-1.418v
my rig on big typhoon air does 1067 + 50% at 1.418-1.465v

Aren't there 2 chipset voltages?
oh you mean MCH/FSB volts, both at 1.725v/1.395v maxed heh

As are mine
I seem to hit a limit to 3d gaming around 430 Mhz fsb with all 4 memory slots filled. CPU is stable up to around 3.85 Ghz with ~1.45V Vcore, but I haven't tested extensively yet. I wonder how much more fsb speed I could get with only 2 memory sticks.
