Help with Q9550 OC to 4ghz

post #1 of 7
Thread Starter 
I spent the afternoon today overclocking my Q9550, and I'm currently running Prime95 at 440fsb, or 3.7ghz. Not sure if its stable yet, as its only been 2hrs, but I did find out that on 470fsb, BSOD occurs immediately on Prime95 startup, and on 450fsb, BSOD occurs an hour after Prime95. So, assuming that my current OC is stable, what would I need to do to stabliize higher FSB with my current ram? Its currently OC to 880mhz at 6 6 6 18 timings. Would I need to increase VCore, and by how much? Would I need to loosen ram timings? Or would I need new ram altogether (hopefully not)? Would want some feedback on this.

Noterime95 tests are all Blend tests.

If you get some 1066 RAM we should get you at least 4.0 with that combo. DDR2 800 aint gonna cut it.

Ugh, was afraid of that. Just a little more, and I'll reach 4ghz. Wouldn't loosening ram timings and/or raising Vcore (its still stock) be worth a try?

You can try to stabilize your DDR2 800, it just takes alot of time with hours of Prime95 blend and may degrade quickly.

I've never heard of that board. Have you found what FSB it can hit?

It is stable with 400x8.5 (FSB adjusted on 1600 with jumper) and 667 (1333) for memory, but only if i set timings on auto. If i manually set timings (7-7-7-20, 8-8-8-20, 8-8-8-24, 9-9-9-24), it is unstable even on 3.4GHz. Memory is Patriot Gamer Series DDR3 1600 (9-9-9-24, 1.8V). For CPU voltage i tried up to 1.3V in Bios (1.24V in Windows) and for memory up to 1.8V. Voltage for NB, VTT and PLL, my motherboard let me choose only between auto, low, medium, high and highest. This voltages i tried up to high.
Is it 3.4GHz maximum with this motherboard? And, why is unstable on 3.4GHz with manually timings?
