i7 920 + GA-EX58-UD3R = ???

[somecanadianguy]

I had my board revert to default settings too...
BIOS said it was because of a failed OC.

How does that look?
Should I manually set some of the voltages instead of having them set to auto?
Could I maybe back some of them down a little and still remain stable?

[3.0charlie]

Either adjust voltages, or lower blck by 1.

QPI/Vtt Voltage 1.150V [1.340V] ----- should be 1.360V

[somecanadianguy]

I wasn't sure about that one.
In my BIOS the 1.36V setting is coloured purple.
All other setting I chose were white.
I'll set it to 1.36, but I'm wondering how much it matters.
Everything seems to be working fine.

[somecanadianguy]

How about the memory?
I have it running at 1080Mhz now... 1.54V
Do I need the extra voltage to run it at that speed?
Stock speed is only 1066 @ 1.5V.

[3.0charlie]

Purple means you are entering a set of parameters out of the reference design. Next is red, which means you better have proper cooling. Purple is fine.

I set up my Folding rig using the exact same parameters, and it's been folding for 48 hours with no hiccups.

Your XMS3 is stock at 1333, 1.5V - not 1066. Running 1080 is low with that voltage. My Gskills in the same Folding rig are running at 1440, 1.54V, even though they are rated for 1333.

[somecanadianguy]

Sorry, I meant default BIOS setting for ram is 1066 @ 1.5V
I wasn't sure if I should push it to 1444 right away...
If I decide to keep it at 1080 for now can I set voltage back to 1.5 or something?

[somecanadianguy]

Is there some good info out there on QPI/PTT voltage?
Can someone here maybe help me understand something?
I've seen people running with QPI/PTT under 1.3V on a 4ghz, 1.375 Vcore overclock.
Why do I need 1.36V for my OC?
I trust you know what you're talking about, but I'm really curious about this.

Sorry Canadian Guy I'm not familiar with your Board....others as Charlie will be able to chime in I'm sure...

One thing though...I would not immendiately crank your Memory that is rated at 1333 Mhz to 1444 Mhz...that is a very aggressive Memory OC!! Concentrate on your CPU OC keeping your RAM speed as close to spec as the divider will allow.
