Whats up?

I over clocked my stock q6600 to 3.0ghz and it passed a stability test in prime95. I got greedy and tried to overclock it to 3.4ghz, but I forgot to set the correct timings for my ram.

My PC wouldn't boot, so I reset the CMOS and tried to start again.

Now the PC will not boot if I try to overclock at all, even if it is with the settings I passed the stability test with. It is booting with default settings though.

My MOBO is a Gigabyte P35-Ds3R

I went 333x9 for 3.0 ghz
set PCI express frequency to 100
Set my ram timings to 1:1
and upped my voltage to 1.350

Any explanations?

If you are running at 1:1, your memory clock (BIOS) at stock should be 533 MHz selected by using a System Memory Multiplier of 2.0. So at 3.0 GHz (333X9), your memclock should be 667 MHz.

It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.
