Help on Phenom 2 x4 980 BE

post #1 of 7
Thread Starter 
I'm new to OC'ing so I'm not 100% certain of all I'm doing. But I've attached the pics I have from OCing to 4.3 Ghz. I'm just confused at why my Vcore is so low and my temp is still decent (not sure when tmpin0 spiked in the attached pic, but thats usually around 30-40 range even at FL) since I've read online many aren't even able to get past 4.2 Ghz stable. I've gotten to 2 hour prime 85 stable and will continue on to see how long it goes. Anyone see something obviously wrong here?

If that stays stable then you have a great CPU. The toughest point of prime Blend is around the 8 hour mark. Often I find overclocks fail at that point. If you can get 12 hours or more then thats pretty good.

Once the CPU is stable then I would look to tighten the RAM timings if possible.

Not sure what tmpin 2 is but its warm. What are the volts are you using for CPU/NB and NB?

Here is prime95:http://www.mersenne.org/freesoft/
Do like dihartnell and check stability.

BTW,u want that CPU/NB up to 2800MHz.

I'll leave Prime 95 running for 12 hours+ then and see how it goes.

NB voltage is 1.1V
NB PCIE voltage is 1.8V
Not sure what you mean by CPU/NB, but I have the CPU voltage set as 1.4V

tmpin 2 starts at that and stays at that regardless of OCing so I had thought that was just the preset alarm setting, but I really don't know. It doesn't seem to be affected by anything (i.e. cpu idle - FL, OCing or not, any bios settings that I've messed with so far).

What does the CPU/NB frequency do? I increased the NB freq to 2400 MHz, but when I tried 2800, it wouldn't post so I'm leaving it at 2400 for now?

So I had to go back to 2000 mHz on the NB freq, prime 95 wasn't stable even after I tried to increase NB voltage a bit at 2400 mHz. Unless there's a good reason to increase the NB freq and lower my CPU freq, I think I'll just lower my NB freq back to 2000. Suggestions?: Comments?

Generally I try to get the NB Frequency to around the real mem frequency. IE 1600 MHZ DDR = 800MHZ x 3 = 2400MHZ. Will imprve overall system performance.

There should be a voltage and a frequency called CPU/NB. Your frequeency control is called CPU Northbridge Frequency and the Voltage control is called CPU NB. These settngs are in MIT section of your bios.

You should not have to lower your CPU frequency to increase your CPU/NB however extra voltage on both needed to keep it stable can cause heat issues.

Here are some links to some Phenom overclocoking guides that will help. The first one focuses on RAM.
