Hi
I have been O/C for around 10 years, and this is the first time I've had to post..
My specs are:
Q6600
2gb PC9200 ocz reaper
Gigabyte P965P-DS3 v3.3
Saphire 4890 1gb
X-fi gamer
500gb sata samsung spinpoint
750w Thermaltake toughpower
Issue: Upgraded gfx to the 4890 from a 8800gts g92, system always ran at 3.3ghz with no issues, 365x9 ram@913mhz. However when I installed 4890 the system reboots before POST screen. Ram will O/C still no issues, however even if I manually set the clock speeds in bios to stock, it will not post. I had initially a seasonic 600w, which I thought was the culprit. I have tried again with the 8800, and it O/C no probs with it in. Amp rails are way over what I need for this set up with the 750w. I have went back to basics, the ram will O/C, as soon as I touch enable cpu clock in bios, it will not post. I have troubleshot all voltages being provided, and upping them makes no odds or causes any reboots so I don not believe power is the issue.
PC is running worse with the 4890 in at stock speeds, than it was O/C with the 8800gts :/
This is doing my head in, any help would be very Very appreciated!
