GTX 460 Overclocking

post #1 of 3
Thread Starter 
Alright. Heres the deal.. aha. I have two GTX 460s that I run sli. They're both in a Alienware rig (sadly) and they were both "nvidia/geforce" cards. NO brand. Running a very low clock, I attempted to OC them. With the low voltage permitted, i decided to Flash Bios them to another card, which had higher voltage permitted. As they sit, they are flashed with a EVGA Superclocked EE bios. They run good, but hot, with 1.1v. MSI Afterburner will not let me take the voltage down, and my current OC on them is 900/1800/2100. At maxload, AND fanspeeds at 100% one hits 82c and the other at 70ish. Would it be a bad idea to keep them as is? My last OC was 800/1600/2000 with same temps. Is the voltage an issue? Is the heat to high? Any recommendations? Tips? I currently do not have the money to get reference cards, to do amazingly fine tuned OC myself.

Thanks.

The max voltage for my card is 1.087v (stock). I have them OC'd to 900 as well but the max temps they hit at full load running in OCCT or Kombustor is 72-73*C.

Are the temps you're quoting at full load? If they are then it's borderline too hot for me. A better option would be to set the clock at 800Mhz since two of those SLI'd are a little bit better than a 580. If possible as well try and use the stock bios and then OC it to 800, you would definitely get lower temps that way versus the one you have now that has it's lowest setting at 1.1v.

Additionally, do you have heatsinks on your mems and VRM, that will also help your card greatly.

I'm hitting 85 on my primary and 83 on my secondary in BF3 at 1.1v. I say don't worry but I like to live dangerously.
