Phenom II 970. Not getting past 4 Ghz - Page 4

Yup it's stable. RipBot ran overnight and I ripped a Blu-Ray movie at CQ CRF 22. I think it's as good as it's going to get.

Nevets, Prime 95 is free. It's a really great tool for system stability. If it passes Prime 95... it is definitely stable. Some people say it's too much, but I think it is imperative that the system pass a prime test. That's cool your computer is running that high. What cooling/mobo you using?

an OCZ vendetta cooler and a msi 790fx gd70 .. its been a crazy couple of days actually last night i hit 4.3 GHz .. LOL but performance is where its gonna be lacking

Well we got my wife a 60 dollar cooler master case, and crammed in a Scythe Mugen Fan after we had terrible luck with the Cooler Master Gemini II S. I hope the store takes it back I had a 34C idle speed at stock speed with that garbage. Anyhow The Gladiator 600 case and the Mugen work awesome with one another. It's almost like the case was intende for the thing, well minus the top side intake fan. Her cheap ol Gigabyte mobo OCed very well and it's stable with auto voltage. On this project we're sitting at 29C idle at 4.2 Ghz which is very respectable for this chip.

I got this going and it Primes!

Once we fix her terrible RAM problem she'll have a rocking machine! I don't anticipate upgrading her stuff for awhile once that is taken care of.

Ahh okay. Download Prime 95 (just Google it) and get a hold of HWMonitor and CPUID. Try and get a working copy of Everest too if you can.

If it isn't priming then I would back it down a bit. Also the Deneb chipset doesn't run any faster over 55C. If you are over 55C on your temp, you may as well back it down because all you are doing is stressing out the chip for no benefit, even if CPUID says it's running at 4.3 you really aren't getting the speed out of it if it runs hotter than 55C.

omg it wouldnt prime for 5 seconds.. so you have one of these chips idling at 4.2 GHz with 29 degrees? thats awesome. my temps are all over the place.. its pretty much every time i restart i get a different number.. but the same things happen on the graphs i see the same behavior. im hoping its just senor issues

I do in this case. Basically because of the way the fans are set up, I practically have four fans taking care of my CPU heat sink. I really like the Scythe Mugen fan BTW... it's quiet. The only downside... it's huge. It's under 50 bucks too.

My other case, or my computer, idles at 38 :/ Only got that one up to 4ghz. Actually after running the machine awhile... it's at 32C, which is still respectable.

While you're priming. Use the small FFT test, it focuses on the proc. Then, watch your temps. If they hit 55 no need to keep testing. Stop the test and back it down.

keep the nb as high as it will go stably. usually, ht link between 1800-2100 gives the best stability.
ive read the nvidia chipsets suck for overclocking an amd.

I just experienced some nightmares myself trying to get that up. However for right now he probably wants to start with the proc and see what that gets up to first. I have another machine that is stable at 4.2 but I had to knock it down because her ram is crap. it still runs great even without the boost in HT and NB. Although the boost in HT and NB frequency certainly don't hurt.

But if the proc isn't stable nothing will be. You'll have to knock down the speed until you are at load under 55 degrees. If you are at 55 degrees load with the stock speed. Get a new case or a new fan.
