Q6600 @ 3ghz. Stable or not?

post #1 of 11
Thread Starter 
I recently OC'd my q6600 from 2.4ghz to 3ghz (in small increments). Fsb 333x9. At first my temps were way too high so I lowered the voltages a bit. I kept fiddling with the values until my pc didn't crash, which it did during gpu benchmarks. Funny thing is, I've been running prime 95 torturing the CPU for 19 hours and counting, with no errors and no crashes. It's still running, idk how long it's gonna take to complete lol. But I think 19 hours proves my CPU is at least stable. I've run evey benchmark I have, this includesrime 95, intel burn test, 3dmark06, passmark, sisoft Sandra, real temp, mafia 2 benchmark (always ran stable until now. My pc crashes 10 seconds into the benchmark), cod black ops sp and mp (they were the only test that failed and crashed my pc before, now they run fine), crysis warhead benchmark, memory tests and various other tests that all passed. But now after reinstalling my chipset and display drivers (thinking maybe this was the issue) and cod black ops ran perfectly fine for 3+ hours (it used to crash my pc and reboot). Now mafia 2 crashes when I run the benchmark. I don't have my gpu OC'd and it runs pretty cool. Here are my specs:
Windows xp sp3 latest drivers and updates for everything
Q6600 2.4ghz stock G0 w/Tuniq tower 120 cooler
Gtx 460 1gb
P5n32-e sli 680i with 1903 bios revision
2gb ddr2 crucial ballistix 6400 stock (4,4,4,12,2t @ 2.2v)
Antec neo 550w psu
Antec 900 case with fans on high, keeps everything pretty cold

My voltages are:
Vcore: 1.337 lol
Memory: 2.2
1.2 HT: 1.35 (lowest I could go to keep it stable)
NB: 1.35
SB: 1.55
VTT: 1.45

Idle:36,36,28,28 Load:66,63,54,51

I use real temp and core temp to monitor my temps and they're fine even at full load. Prime 95 is still running as I speak..

Thanks for reading and any helpful advice is appreciated.

I dont think your RAM can take the stress of your OC. try 2.8Ghz, if its stable then tip toe your way to 2.9ghz, good luck mate.

My board sucks when it comes to OC'ing quads (so I've read) and it's got dead spots. Mine for example doesn't boot from 2.79 to 2.99. None of the fsb values work. Prime95 has been running for 23 hours straight, not one crash. I've also tried memory torture for 6 hours yesterday with no crash either. Should I try OC'ing my ram to something that would go nicer with the OC? I currently have my CPU and memory fsb unlinked. Linking caused instability. So manually I couldn't hit anything between 2.80 and 2.99ghz

It's this asus p5n32-e sli board.. I'm getting a complete new build soon but for the meantime I wanna get this stable.

Yeah sounds like its not the CPU causing the instability, mine is stable at decent voltages up until about 3.8-4Ghz, then I have to give it a noticeably larger bump in voltage to hit 4.1

I run mine at 3.8 most of the time though

So what would be a good memory speed so the CPU clock isn't too big for it?

Could it be the ram causing my pc to crash during the game benchmark? I just have prime95 running like it's nothing right now lol

Good quality 667Mhz RAM will be good, maybe stick a heatsink on it and OC your CPU, every Mhz your CPU goes up, your RAM goes up to, so if you have some top speed DDR2 (1066Mhz) when you OC your CPU the RAM will go above the Mhz that the motherboard supports, I hope this helps mate.

Yeah my ram comes with heat sinks on it. I have 2gb crucial ballistix 800mhz

My mobo's stop ram is pc2-6400 800mhz, but I have OC'd above that when I linked the fsb for lower OC's (from 2.5 to 2.79) but after that I couldn't maintaint stability. Since prime95 has been running so long I know my voltages and CPU fsb has to be stable. Now I'm going to try to OC my memory and maybe even gtx 460.

Should I leave the timings at auto and link the fsb?

Yes leave your RAM timings as normal, or you can manually force them to run at the specified timings, as mine wouldn't run at the correct timing specified by the manufacturer.

Also, make sure each time you over clock your CPU, the RAM speed isn't going too high either

I oc'd my ram and left the timings to
Auto. It's currently at 1066mhz now and looking stable. Running benchmarks.

Btw, after 24 hours of stable CPU torture with prime95, I stopped it. Launche mafia 2 benchmark and my pc crashed.

I never oc my RAM, I dont normally see the benefits

Try sticking it back to stock settings and benching with the OC'd cpu
