Overclocked GA P35-DS3R won't boot from cold..

[apollo911]

I am new to overclocking and have a P35-DS3R Rev 1.0 Bios F10 with E6750 2 x 1GB Crucial Ballistix PC6400 .

It runs at 333Mhz FSB at stock and I overclocked to 400FSB at 1:1 .. system stable for 12 hours running Prime95.

I changed the multiplier to 2.4 so RAM running at 960Mhz , again stable .

BUT I cannot boot from cold at any FSB over 350.. it retries and at the 3rd attempt reboots at default values.

I haven't changed any voltages, but given the system is stable, any ideas what could be causing this?

It boots fine at FSB 333, 340, 345, 350 .

This is a gigabyte p35 problem. The only one I've not seen this on is the DQ6, and it wasnt in my shop long enough to test it extensively.

Thanks, at least I'm not wasting any more time trying to 'fix' it.

Using Standby is a workaround.
