Update: 535 FSB on Gigabyte DS3.

[Kunaak]

ES 6400, 6x multiplier. 1.4 volts. (overkill for the hell of it)

VMCH mod, at 1.75 volts.
Vdimm mod, at 2.7 volts.
VFSB at .3+
Bios F3.
C1E disabled. TM2 disabled.

booted into windows at 470 FSB. used Easytune5 to get up to 533.
can boot up into windows at 480 about half the time. 470 about 95% of the time. will not boot past 490 regaurdless of voltage or ram used.

there is a hardwall at 533.
getting to 533 is rather easy, but right after it, the board just goes nuts.
even 1-2 more FSB and the board just starts acting crazy... like the screen will go black, then turn back on, or it freezes... then goes again, or the mouse goes away, then comes back...

Hardware used.

OCZ 600 watt powerstream.
X1900XTX.
1 gig of Corsair 5400UL V1.2.
Sumbeam Silent Whisper heatsink.
Swiftech MCX159R for chipset.
120mm enermax fan over the ram.

not intended to be shown as stable, just the max I could do

I just got this CPU about 4 hours ago, still playing with it

CPUZ Validation. (Cas is reported wrong, should be 5-5-5-15)
