So you have everything set to auto? Are you just adjusted the FSB for your OC?

Thats an issue right there.. Auto helps in some areas, but usually not real helpful in OC'n.. tends to push voltages higher then needed=higher temps.

try these, I went off of where I'm at.. but the other fellas know more then I!

DRAM
DRAM Voltage .........1.800V.........: Auto
DRAM Termination .....0.900V.........: Auto

Channel B Reference ..0.900V.........: Auto

Again, some of those numbers are where I'm at, and so far I'm stable at 3.83.. each board and each chip are different.

Watch those temps.. cracking 70 is getting warm brotha! post back and let us know.. i'm sure someone will be by soon to laugh at me but this should get you going

Set your RAM voltage, Vcore, CPU Term, and MCH to stock. Increase FSB, and if you fail raise Vcore, if it still fails raise CPU Term, if that fails raise MCH.
And the beat go's on da da dum, da dum.

Alright I'll start editing all these numbers in an hour or so. I know 70 is a little warm but the stock cooler used to hit that rather quickly so if it's been running prime for 12+ hour and it's at 68 C I figured it would be ok for a day.

I appreciate the help, will post results. (Also yesterday I did try to set a few things and I kept getting the three restarts and bios reset, these and the stock settings are the only ones that seem 'stable' and will boot)

Yes 70 is ok.. but I think we can do better

You may have to re-seat it, but lets try and get some of the voltages under control first.. by manually setting a few things you may notice the temps will go down.

But remember, those numbers are what I have it at (now prime is running for 3.93) and I'm running at 60 at load, but since you're hitting almost 70 at load, those numbers may be higher then what you need to achieve a 3.5..

stick on here, these guys helped me out tremendously.

Still at 3.4Ghz but I've changed everything to match what you posted with a couple exceptions.

At your settings everything loaded and looked good until I ran Prime95 and right as I began it with a blended test it restarted the computer.

So I blindly raised the cpu vcore to the next step from 1.281 and then changed the sys mem multiplier to 2.66D I believe it was to hit 1066. Boots and runs fine doing blended Prime95 now and so far everything is stable. Temps under load in prime are 63ish C but I haven't done Intel Burn Test yet which seems to really put on the heat.

I'll get the exact bios settings in an hour or so while it does prime a little longer and then get the vcore back down.

Good.. we're making progress.. Temp is alot better.. but for your case yes you'll have to run intel burn to compare the temps for a solid 'before and after' comparison..

When you run prime, change to small ffts.. stresses the CPU more. More guidance for your situation will come in due time on this thread.. be patient..

Getting some errors in Prime in the 3rd core: Rounding was 0.5, expected less than 0.4

I bumped up vcore and term up a bit, but want to stop and check in with you guys before I proceed and break something (still learning)

One thing I noticed is the Dram.. on the P5N-E I would choose unlinked and keep the memory alone, how do I control that on this board?

Stock speed is 533, now I'm sitting at 564/1128mhz

Running Prime again to see if my bump in vcore is enough but I'd like to get memory back to stock (1066).

thanks in advace

This is to rule out your RAM as a problem!

Down multiplier from x8.5 to x6.0 to test FSB/NB stability. Run Prim95 Large FFT's for at least 6 hours! If you wanna take a quicker run, click Large FFT's, then go to custom and write 5 min instead of 15 min. If stable, up the multiplier to x8.5 again. Then run 10 passes of IBT (High, very high or max mem) to check if CPU is stable. If not, give it more Vcore.

If this does not help, try playing with your CPU's reference Volts. You should have two of them. They need to be finetuned for 460FSB + when overclocking Quads.. Here is a guide

When you get stable, try upping RAM speeds again. First you up the mem multiplier to x2.4 again. Do not touch anything else without testing stability first. Use Memtest for Windows. Open two sessions and type in 1500MB for each of them. Let them run two passes to check mem stability. Also use memtest for DOS. Prime95 Blend testing is also good for testing mem stability. I suspect that Performance Enhance: Turbo gave you trouble.

Awesome.. thanks for the input turrican9.. I'll make those changes when/if prime fails.
Its been running error free for just over an hour, I used to get an error at the 23-24 min mark.. so I'm going to let it go for as long as it can.. or if I need to get some BF frags

As for the Performance Enhance setting, does that really make a difference/impact, besides potentially causing problems?

No, that Perfomance Enhance in itself do not affects performance very much, as long as you have the Static tRead Timing at manual. That Performance Enhance controls the Static tRead timing. Static tRead = Performance Level. And your setting: 9 should be perfect for your setup.
