965BE overclocking: Max safe voltage

post #1 of 8
Thread Starter 
I had a 965BE (I think C2, but I'm not sure) and I had it overclocked to around 4Ghz. However, in order to achieve that, I had to push the voltages up to around 1.5V. I left it there 24/7 for about 4 months. Well, I came back from my honeymoon (during which time the computer was off) and turned my computer on for the first time in a week. It booted just fine at the settings I left it. However, 2 hours later, the screen went garbled and shut off. After that I couldn't get the computer to post at all. Fans would spin up, but nothing happened on the screen.

I tested the video card (5870) in my wife's computer, and it didn't work, so I RMA'd that. Still, the system wouldn't boot. Therefore, I RMA'd my CPU and motherboard. I got both of them back, and Gigabyte told me in a roundabout way that it wasn't the motherboard. However, AMD confirmed that the CPU was infact dead and sent me a new one.

Now that I have my system working again, I'm back to overclocking. The best news is that the 965BE RB-C3 overclocks like a champ. It's super easy to hit 4Ghz (like 1.425V 24/7 stable vs. 1.5V on the other chip.) However, I do not want to kill my CPU again.

My question is since this is a newer revision, is it possible that the limits are different as well? Some guys are saying 1.5V and beyond is fine, while others are saying that you should stay under 1.5V. Which is it?

I'd love to get 4.2Ghz out of this chip if I can, but I need to know if I'm going to kill my CPU in the process.

Any help is appreciated.

I think the general consensus around here is that 1.55v on air/water is the limit, as long as your temps are fine (62C is the Max temp for these chips).

1.5v really shouldn't kill your chip. You probably just had a lemon.

I've gone up to 1.6v before, however that was for a (HOT) suicide run. Keep it under 1.55v 24/7, probably best to be around 1.5.

What are you using to extract the max temperatures? Currently, I'm using Prime95 blend test for stability testing.

BTW, I had the chip for 1.5 years before it died on me, and I kept it overclocked most of that time. I guess it was possibly a lemon, but wouldn't it have died on me before then?

Some people can run these chips at 1.6v 24/7 for months without damaging them. 1.6v is might be the max if you keep the load temps under 55C.
Edit: Also Phenom II x4 chips are designed to handle higher voltage better than Intel.

According to AMD, The dragon platform can handle 1.55V all day long.

C3's do much better than C2 revisions,so 1.5v on most C3's is nothing.Use your temps as a guide.If it stays under 50c you are fine for 24/7 use.If it's pushing 52-55c,you might want to back it down.Make sure you do this in the warmest part of the day.

It only pushes into the 50s if I stress test it. Normal use/gaming, it doesn't get anywhere close, even on games like BC2.

I may invest in a new cooler too. My TRUE 120 is starting to show its age compared to some of the newer offerings.
