Here is the system,

e6600
asus p5n-e
2gb 5-5-5-12 800mhz ram
bfg 8800gts 640mb (oc'd 50mhz by bfg)
blue orb 2 w/ artic silver 5 paste

voltages:

vcore set to 1.3v
ram: 2.178
NB: 1.208

Timings:
fbs: 1200
ram: 820
pcie: 103

hottest core temp: 42c

It's crashing while running pcmark 2005 cpu/ram tests and stress prime 2004 at the same time.

When I run 3dmark 03 it's actually scoring 2000 points lower than stock.

Any ideas?
 
Well if you are crashing, then your comp isn't stable at all, so you need to either lower your clocks or raise the voltage.

I lowered the pcie to 100 and turned the case fans to max.

It ran stable at 2.8 ghz, @ 34c.

I'm going to try 3ghz now...
 
stock vcore on that is like 1.35 I think so little more vcore would not hurt but watch your temps.

If you are using coretemp and getting 42C under load that is almost too good, indicating the cpu is being undervolted. go 1.37 1.38 around there if you can, I dont know what you have available for voltage increases but dont even sweat it till you get near 1.4 where you better stop and find out some more stuff.

using coretemp under load dont even sweat it till 65C and thats still way below any danger zone

Thanks, I knew about the 65c, you are very informative. I brought it up to 3.0ghz, but it wouldn't boot, I was too scared to bring up the vcore, but will now bring it up one click, w/ your info.

I'll bring the vcore to: 1.3685

It' running great at 2.92. Something about that round 3.0ghz would make me proud. ;p

I brought the ram up to 833mhz, do you think that's safe? For 800mhz 5-5-5-12 ram? It's corsair TWIN2X2048-6400
 
I just can't get it to run stable past 2.92.

Sigh, I'm a little disappointed.

I am assuming the 5 5 5 12 is the advertised speed.

right around there (840) you will need to give the ram 5 5 5 15, is it still at 2.1 V or so ?
, that where it should be, its where mine is happy at for voltage, if I go higher it actually doesnt like it and overclocks worse. :(

No worries you cant actually hurt ram with speed. Only thing that can actuall hurt it is if you give it too much voltage and your first post said something real close to 2.1 and corsair says that is fine for 1.9Volt XMS series. I run mine at 2.15 but wont go any higher. so it might lock up at higher FSB but it wont hurt it a bit.

Thank you! Do you have any advice to get it to 3.0ghz? This machine is for a friends b-day, I want it to look all impressive. ;)

The ram is at 1.9v, I notice if I screw with it the machine goes completely unstable.
 
The P5N-E has FSB holes in it, just like mine

I couldn't get my e4300 to past 2.6 ghz, and I just didnt try even.

Try 1340 FSB. See if it boots.
 
Your NB voltage seems really low . I've not gotten anything stable that low and if memory serves me correct most people are having to run higher than that. I can't remember the setting in the bios for that mobo but I'd try to bump it up.
 
Yeah bump it from stock to 1.39, and put all the stock settings in. Dont let the auto do it for you since it can actually lower it.

Hey, I said screw it and went 1.38, (I didn't see your reply) and bamo, stable as a mofo!

WOOOHOOO!

Thanks all.... 3.2ghz? :x
 
I'd say your good to go up to 1.4vCore(thats what I run mine at) But watch your temperatures.
 
IF you want to higher it more than 3.2 gigz then by all means just higher your fsb an dhigher your volts. But hey, isnt 3.2ghz better than 2.9? On stock?!!?!?!:p
