GTX460 Clock Drops - Page 2

Well, considering I only have one monitor...

I know the GTX460 drops its clocks when idle. It drops to 405 and then to 51... sometimes. Either that's not meant to happen or it's a new feature for Fermi. Hopefully the latter.

Perhaps if I show you my overclock?

Oh, here's a thought. Maybe there' is something wrong with the BIOS? Is there a BIOS update I can try for the GTX460?

I mean, I've noticed rather strange things happen with temps, clocks and fan speeds with Fermi when more than one monitoring program is open at the same time. For example, I've seen people report strange behavior with temps and clocks when leaving both Hardware Monitor and Afterburner open; but when they close one or the other, everything is fine again.

However, after seeing this overclock, I recommend raising the voltage a little bit and try again. If it continues to happen, then keep raising the voltage and trying again over and over until it seems obvious that it's never going to change.

Unfortunately it's happened with both AB and GPUz and just AB. Also, I've noticed it definitely happens faster when the clocks are higher.

Fair enough, maybe I have been a little conservative with the voltage. I've read people getting higher clocks with stock but then they never really said what their stock voltage was. Mine is 0.0987, in case you wanted to know.

Oh. Then definitely increase the voltage. I mean, bump it up a little and try it again over and over until it stops downclocking under load. After all, this is somewhat of a big overclock.

Righto, all there is left to do is to wait. I'll update the thread in, say, 3 hours or if the clocks drop. Whichever comes first.

Damn, that was fast. Clocks dropped again T_T.

I had the voltage at 1.050. Time to bump it again.
