Help with GTX 460 overclocking

[sram]

Hi all. I just upgraded my video card to the infamous GTX 460. Being the enthusiastic me, I decided to overclock it. I downloaded EVGA precision, MSI afterburner, and GPU-z. Precision and afterburner are almost identical so I settled with afterburner.

I got some questions.

I was able to reach 950 on the core clock and 2300(1150) on the memory clock and was running the performance test bench program from passmark.com video card tests as a stress program you can say. It didn't jam until I went over 950 MHz. But, the benchmarking results didn't increase which had me worried for a bit.....why is that? I think it is not important though, I shouldn't really worry.

I ran FFXIV benchmark and the computer locked up. I lowered the overclock a little and was able to run it without problems. I scored 4100 instead of the original 2666! I was really happy!

Then I decided to test with OCCT( an overkill?). It generated errors so I started lowering the overclock but it kept generating errors until I reached 851 MHz on the core clock and 2000 on the memory. I'm now where OCCT tells me it is fine. Should I ignore it and go by FFXIV benchmark?

Or maybe this is a better question to ask: What is the best GPU stress program? Furmark? And how do you use it? Just like you use prime95 ? Keep it running for an extended period of time till you feel that your overclock is fine? And what happens if it fails?

Except for oblivion, I don't have any other game installed currently. Will running it be a good stress test?

Also, in Afterburner, why can't I go above 1050 mV for core voltage? And what is the absolute maximum for the 460 in your experience?

It is my first time overclocking a video card, so bear with me.^_^

Thanks to all.

Hmmmm, is this the wrong section? Should I put this in the overclocking and cooling section?

Come on gurus, share your experience^_^

Every card is different, but you had a serious overclock. My overclock is 845/1690/2000 and it is stable with Furmark, and I am using stock voltage of 1.025v. I would run that program to check for stability issues, but it sounds like you backed off enough on your original overclock that you are probably stable.

900+ truly stable is tough.

for a stability test my preference is unigine heaven, let it just run for 30 minutes. set AA and AF pretty high to really stress the card out. it wont get your card the hottest but for stability is seems great detector.

I just found out something. You use EVGA OC Scanner to make sure your overclock is error free. Will go try that now.
