not noticed if running stock i thought vdimm was 1.9v What memory are you using most performance ram nereds >2v
No it's still with us

Whaere dis you read tyhe voltage , what is it set to in bios.

9x400 12HR Prime Stable worked for me may be a strating point for you see bios settings at end of post.

luck
I'm using a pair of Crucial Lanfest Limited Edition 2 GB right now. When I set everything to auto (timing, voltage, etc), it start with 1.94v as detected by uGuru. Everest read it higher at 1.96v. I know this voltage is normal. But, this is not what I mean.
I believe we have a little misunderstanding here. Sorry for being a little confusing for you...

Please see this picture below:


See the red line? The DDR2 and DDR2 VTT limit offset are way to ridiculous. I believe that this is caused by the erronous BIOS, right? I then have no option except to set OFF the BIOS warning for DDR2 and DDR2 VTT voltages.

About the vcore for my Q6600, on my previous Commando, I set it to 1.275v in BIOS, and it was idling at 1.24v. When I running Prime95, it dropped to 1.20v only! A huge vdroop, wasn't it? But, everything was running normal at that setting. If I dropped the vcore even just one step, say... to 1.2625, the full load vcore would drop below 1.20v, at 1.18v, and I wouldn't survive the Prime95 test even for 3 minutes.

And oh, before I forget, I would like to thank you for your great review there. I was googling to find the pros and cons of this board back then and I found Clunk's review alongside with yours.
Thanks for your advice bro. Will try that setting very soon.

2. Also strange, didn't have that problem either
3. It's not buggy as long as you don't push it too far. You can easily run mem@1000 with the 4:5 divider, it just gets unstable over 1100 or something

Recommended settings for your quad@3Ghz:

- Set Vcore according to your CPU's needs
- Set Memory Divider to 1:1.25
- Set memory Voltage to 2V
- Set FSB to 333
- Leave all the other voltages at stock - worked for me with 3 different boards/Q6600's

--> you should be running stable. If not, come back here

For 3.6 Ghz I'm using VTT 1,3V - MCH 1,35V - ICH 1,20V
Just don't expect to be running 3,6 stable out of the box on air, not all CPUs can do it and also the mobo might need some fine-tuning as well.
About the keyboard problem, I think that may be the problem only happened to USB keyboard user, meanwhile I'm using an old keyboard with PS2 connector here, so I don't ecounter the same problem.

And about C1 problem, I have done more testing. And the result is when I cold boot the system (unplug the power cord), the problem doesn't happen. but, when I warm boot the system, it always give me that long beep sound. Dunno what's wrong after all, but everything is working just fine.

Thank you also for your recommendations bro. I'll take those into my high consideration alongside with Supershanks'.
I'll post the result here soon.
