To summarise this board sucks with G6600 but I suppose i shouldn't complain too much ... something is better than nothing.

Yea, it's tough to get above the 3GHz mark with a Q6600 and this board. I see that you can post @ 375 but not @ 333.....interesting. Makes me think it is a RAM issue. Running 4 DIMMS will definitely strain both your NB and VRM regulators.

A couple of things you can try- Use 2 DIMMS instead of 4. This is the preferred OCer setup. Also try underclocking your RAM to an even ratio- ie 3:1, 2:1, 5:4 instead of trying to run an odd divider like 16:17 or 9:32, then reduce your Vdimm as much as feasable to keep you stable. To calculate take the QDR divide by 4.....This is your effective bus, multiply by 2 for DDR.

I've said it before, and I'll say it again......This board lacks adequate current (amperage) regulation to really support a good OC on a quad. Keeping all your voltages as low as possible should help achieve a better OC than blindly increasing voltages to achieve stability. Find your lowest voltages for STOCK speeds, increase from there.

RAVIN - any chance you can post your Vcore/NB settings... I'll remove 2Gig & try it out.

Dude the card is busted... you should have said it happened once before in your first post... you can stop posting about it now and buy a new card.

Though earlier in the year, it was doing the same thing to my old mobo. Fixed itself after I left it alone for a day.

More detail: It worked once. Then, when I brought it back to my room and tried it, it didnt boot. It powered on then right back off. Didnt even get to the splash screen for the mobo. Tried it with PCI card. Worked fine. Tried messing with the BIOS setting for primary display adapter, no dice. Didnt work either way.

you might need more voltage try 1.375 but dont go any higher (well you can its your comp, but thats at your own risk)

Have turned all my fans OFF and cannot get this thing to idle higher than 42C, last night Idle was about the same with Fans running full bore. I cannot go 1hz higher than 1200Mhz on FSB or it will freeze, last night was at 1300Mhz without a hitch???

just updated to the new bios 0801 or something. and i ran Aquamark and got this:


before the update i was getting 129k>134k:S

this board has impressed me more and more everyday!

[ru7hl355]

just ran 3d mark aswell.



thats on my safe OC 600/900 i can go to 625/950 so dunno what i will get :S

cpu aint exactly OC'd either only 2.61ghz...

my advice, upgrade to 0801 rofl!

I have tried to pump up my FSB past 1300Mhz and cannot be done. I was thinking it was temp issue, and the C2Q was throttling at anything past that mark. I checked my temps in Core Temp, Asus Probe, and SpeedFan. What I found was a huge discrepency between all three. From the forums, it is clear to me that the Core Temp readings are probably the most accurate, but why the constant 15C difference between CT and SF?? I have gone back to stock to figure this out (Was hitting 80C under load according to Core Temp)...maybe a good cpu and HS lapping is in order?? Thanks again for your help!!

im using 0608 are you saying flash the bios
are your 3dmark scores going up
will i have to overclock my system again

[MuffDiver]

anybody else try 0801

I found this at the Asus forum:

Hi guys,

Sense i've seen fairly many people havening similar problems overclocking The Intel Quad Q6600 on the ASUS P5N-E SLi motherboard I feel obligated to share my new findings, so here goes...

The two last days I've been trying to figure out the problem behind why i couldn't overclock my new Intel Quad Q6600 on the ASUS P5N-E SLi motherboard. And i finally know the answer.
With the 0608 bios that is needed too support the new Intel Quad Q6600 rev. G0 i had this irritating phenomenon. Every time I rebooted my PC wouldn't start. Too fix this I had to remove the power cord and try too boot the system back up. On the second try in most cases the system booted up and continued its way on to windows. Finally in windows the system was stable and continued in this way. So the only thing now driveing me crazy was every system reboot! =p

I started updating too different bios ones again but non of them would keep the system stable well inside windows, and the boot up problem was still there. But i was determent to isolate the problem so i started to look real close on what changed after every bios update and it was a really simple change.

In bios 0703 under Advanced/CPU Configuration ASUS had made a change too have
- CPU Internal Terminal Control too default enabled, and with this enable overclocking would fail and system would either hang or give blue screen during Prime95 torture test (with is a program for checking if your system is stable) at least this was the problem for me. But with - CPU Internal Terminal Control Disabled and the 0703 bios that doesn't suffer from the reboot problem my system is now running at 41% overclock and is very stable. More on my settings will follow for the ones interested let me know


IF you try it let me know how it works out.
