Overclocking G0 X3210 - Max 3.2ghz?

[Snakebitten]

Just received a X3210 - 2.13ghz Quad Core. G0 Stepping. I can overclock it to 3.2ghz with minimal voltage bump, 1.33-1.35V @ 38C idle 50-52C load. Which is fairly decent still.

However, I can't seem to get past 3.2ghz unless I crank the voltage to like 1.5V.

I tried 3.45ghz @ 1.5V and booted into windows but seemed unstable, explorer errors, etc. If I don't use 1.5V it's blue screen on windows bootup.

I think I've ruled out FSB and memory issues. I've tried 460fsb x 7 = 3.22ghz @ 1.35V and worked 100% stable, prime 95, games, etc. This setting stressed my fsb and memory harder than 400x8 = 3.2ghz.

Any tips appreciated, I have a feeling I just have a bum core, but open to suggestions/advice.

This is on a Abit IP35 Pro, Sycthe Ninja Heatsink and using 4GB of OCZ Plat. Revision 2 800mhz 4-4-4-15

My X3210 B3 can't get over 2.8 ! Good luck on the G0.

What power supply, graphics card?

BFG 8800GTS 640mb and BFG 650W Power Supply.

Power readings via bios look normal, no flucuation. I'm starting to lean that I have a core not capable of high speeds unless fed voltage.
