It's posted 2.85Ghz, but usually gives me a blank blue screen and locks up.

Have you tried running your ram at a divider in order to rule out the CPU as the cause?

I running DDR400 at 333Mhz. Tried going lower but makes no difference, although like i said before the system was unstable at 2.75Ghz. I now have managed to boot up into windows at 2.8Ghz by raising the CPU voltage to 1.5volts. But it freezes in 3DMark, what would cause this?

It seems anything around 2.75Ghz or over is unstable for me, i have settled for 2.7Ghz which is perfectly stable. I am at a loss with making 3Ghz, but with Corsair Value ram, 2.7Ghz is quite a reasonable overclock me thinks.

Just remember that no two componants are the same...just because someone else with an identical rig managed to oc to a certain point doesn't meant you will be able to. That said, I don't see why you aren't able to hit 2.8. (Especially since my 3400 was at 2.6, and was only limited by my stupid psu.)

All i ever seem to get is lock ups to be honest, if i manage to get to windows it may lock up there or during a stress test like 3DMark05. But at the moment it works fine @ 2.8 during stress tests and is completely stable.
You're using the "shotgun" approach to OCing. Change one thing at a time. That way when something goes unstable you will know what is limiting your OC's.

Oh btw, on occasions my USB will stop functioning at a certain clock rate, plus do you have to change the PCI Frequency to 33Mhz rather than the default Auto? Plus would a Bios update be worth while?

I'm using a Jeantech Artic 600Watt PSU, which is a kick ass premium PSU.

USB: Disable "Legacy Support". NB>SB bus speed will affect USB stability.

Locking the PCI frequency can give you more stability. Do you have any PCI devides installed though?

Not really a "kick ass premium" PSU:

remeber if your going over 250mhz on your fsb you need to set your HT Freq to 3x.Having it set higher with a fsb over 250 will cause instability.

You MUST lock the PCI Frequency. If that frequency goes over 37MHz (Where most boards crap out), you can loose data and such from your harddrive.
I've never heard about JeanTech, so that's possibly your problem.

That is not always correct, most boards can take 1050MHz on the HTT without problems. A few can go up to 1100, and almost none can go higher.
