whats your 24/7 sandy bridge overclocking?

post #1 of 65
Thread Starter 
i know there's a 5ghz club and voltage/mhz post but what is your 24/7 sandy bridge overclocking.

4.9ghz
1.44v
62c max load
7 hours prime 95 small fft

This is my experience. i wanted to have sandy at 4.8ghz 24/7 and notice that in linx i can have it at 1.382v stable all day but prime95 small fft would fail within the first 10 minutes. I wanted a 24/7 overclocking that it was rock solid stable but with good temp. i notice that to get prime95 stable i needed this.

4.8ghz 1.424V 60C
4.9ghz 1.440V 62C
5.0ghz 1.504V 72C

After all my testing i have set my 24/7 overclocking to 4.9ghz 62c max load.

Please people, i see alot you running IBT and linx. I have tried both in max setting for extreme stress and both passed with much less voltage. Prime95 is the only true sandy bridge stress testing software you should be using. This is not a competition of who has the better cpu by trying to run light Stress software and proof that yours is better than anyone else. If your overclocking is not 100% stable in ANY stress software, along the line you WILL have problems in your OS.

Prime95 is the only true sandy bridge stress testing software you should be using.
Another good stress test is the lesser known checkers DB6 benchmark. It runs about 4 hours if you have a very fast system, and under 3 hours for my 5.1 Ghz i5-2500K.

In my experience, it h as caught things even Prime missed!

Why does it matter? It's a 1,000$ cooler.

Personally, I think you have a bad chip. People have been getting 5.0Ghz @ 1.425v.

That's stable enough for 24/7 given your temps are under 75C or so.

Look at the volts on that puppy, it makes most people cringe, but when you run sub-zero that is perfectly acceptable.

I've got 4.60GHz on 1.32v 4 hours prime 95 (blend) stable. Is small fft much more demanding? I haven't tried lower voltage or more overclock yet. I figured I would get a solid 24/7 4.6 clock before exploring further. I'm actually temperature limited if I try to go higher.

But that's not multi-threaded. How can it be stressing all the cores?

I ran even more tests than I had shown in that post, including a 24 hour prime torture test.

Run the checkers bench and see if you pass the test.
