X3440 - Getting 4GHz stable

post #1 of 5
Thread Starter 
Okay...I'm giving in and posting.

I've been trying to get my 4GHz overclock completely stable, and I just can't seem to do it. Either it's unstable and blue screens, or the voltage is too high and OCCT aborts the test. Do note that this is with HT on...I don't want to turn it off

Here are the base settings I was using to try for 4GHz:
200x20
Vcore: 1.350
QPI: 1.350
PLL: 1.900


and I was upping the Vcore as I got blue screens. I can't go very far above 1.350 on the Vcore before my temps start getting too high.

I've since turned my settings down to:
200x15 (3GHz)
Vcore: 1.300
QPI:1.350
PLL:1.900

Right now with the above settings, I'm idling at 40c. I have a Noctua NH-U12P cooler and I'm using the included NT-H1 thermal paste. I've tried reseating my cooler and it didn't help lower the temps at all.

I think I may need to invest in some better fans. I have the Noctua fan that came with it, and I added a cheap Rosewill fan. Would buying better fans lower my temps dramatically, or does my problem lie in the settings I've been using?

Turn PLL down, that is way too high. Try 1.8-1.82v.

Put your memory at stock or lower frequency. I find that it helps eliminate some variables when overclocking the CPU. You can adjust it later.

Use the 19x multiplier. Even multi's seem to require more voltage on Intel CPUs.

I've turned the PLL down to 1.86 (my motherboard goes from 1.8 right to 1.86, and 1.8 is the default setting) and I'm at 211x19 right now.

So:
211x19
Vcore: 1.350
QPI: 1.350
PLL: 1.86

I just tried to run an OCCT test and got an error on core 4 within a minute or so. Temps were also around 75c by then, so I'm thinking I'll definitely need to do something about my cooling situation to get 4GHz stable. Intel says the Tcase is 72.7°C. I was getting 67c load temps at completely default settings...

That does seem a little hot at stock. You are fine up to 100°C, but try to keep it below 90°C.

Try a lower overclock, 3.8-3.9GHz. There could be a large voltage gap keeping you from 4GHz.

Thanks for the suggestions SimpleTech, I do appreciate it. Also sorry that I haven't gotten back to this sooner- I had my wisdom teeth out on Tuesday and I haven't felt up to overclocking before today

Anyway, I tried the following:
200x19
Vcore: 1.300
QPI: 1.350
PLL: 1.86

and got a blue screen while running OCCT. When I tried the same settings with a 1.350 Vcore previously, the temps were too high. Right now I have the Vcore set at 1.3125 (I think?) and am about to start another OCCT test.

Edit: Too hot at 1.3125, unstable at 1.300

Temps:
Attachment 188716

Attachment 188717

Attachment 188718

Attachment 188719

Edit2: Well, I seem to be stable at 3.6GHz at 1.30 Vcore, but I was hoping to get higher, after all I was running 3.6GHz on my old Q6600.
