I raised my fsb up slowly from 260ish to 370 (3.33mhz)and used intel TAT to check freq. and load cpu up to 100% for 20 seconds, then CRASH! wanted to get the fsb up to 400 (3.60mhz) to have a 1.1 ratio with my ddr2800 ram. I am using a Zalman cnps9700 fan/heatsink and 5 120mm case fans( 110+50+50=210cfm coming in and 110+110=220cfm going out, almost neutral) So I lowered my fsb down to 350 (3.15mhz) and loaded it up again to 100% for an hour or so and no crashes, so it seems to be running stable. I am new to oc'ing and have never fooled with vcore voltage or anything else for that matter, i have a pretty good board for oc'ing, Asus p5b-e, should i oc my ram next? A-Data ddr2 800 (2gb) and wintec ddr2 800 (2gb), or my 7900 gs? also does raising fsb cause more heat in the chipset? i replaced stock fsb heatsinks with bigger, better Zalman (sb) and Enzotech copper (NB). Thanks guys...
 
RAM is a lot harder to OC, but if you're CPU is stable, don't mess with voltage.

you can OC your GPU.
 
I got my E6850 to 3.6Ghz yesterday..... I had OC'ed it to 3.5 before that and just didn't have enough volts. I am gonna take the E6850 to 4.0Ghz sometime.
 
It doesnt sound like you even raised the voltage for the CPU...

Raise it then check to see if it's stable.
 
Yeah, it seems that you didnt raise the voltage. I'm sure that if you raise it a little, you can go higher. I currently have my E6400 at 2.9ghz. My goal is 3.2, but I am waiting for a new HS&F from Newegg. I raised my voltage from the stock 1.325v to 1.35 and it's perfectly stable after 8 hours of Prime95 testing. Just a little hot.

Yes, he does need to up the voltage... I got my E6850 to 3.74Ghz, on 1.40v. At stock idle it runs at 23*C....:D Once you up the voltage, you will start to notice where the voltage walls are, I did.

On my E6400, the wall for me is ~3.3Ghz, once I go higher then that even with a voltage of 1.56v, I can't get it stable. And when it's up that high I reach temps of 75C load before the PC shuts down.
 
As others have said, you need to put a bit more voltage on the CPU. A safe setting would be 1.35 to 1.4, maybe 1.45. The main thing to watch is temperatures. The Quad core series can't handle temps that are quite so high.
