Odd over clocking issue(Q6600)

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.

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?

Post a direct link to your specific RAM, showing quantity, SPD timings, and voltage. Also post the VID of your quad using Real Temp--> "Settings" page, and the stepping of the chip (found using CPU-Z--> CPU tab--> "Revision" field).
