Overclocking the gtx 275 co-op

[Feänor]

Hi everyone. I've managed to get the gt200b core to 700/1620 core/shader (i'm folding, so the memory is at 850, less heat and less power usage). But i can't find a way to increase voltages beyond 1.17v. Is there a way to do so, and if possible, without flashing anything. I've done it in the past, and it went well, but i'm more of a software mod than a hard modder. And second point, the G92 core, who's at 783/2000@1,200 v, maybe can be increased even more?

By the way, temps are not a problem, each core is at 70, so i think i can really go higher before anything bad can happen.

Please help me get those shader in the stratosphere!

That's actually not at all bad on either. My G92b (GTS250) only gets to 1836 on the shaders, and my GT200B (GTX260) only does 1480

I don't know of any ways, but good luck

I know i've got two cherry cores, as i've not see anyone with 1620 on the shaders on a gtx275, and 2000 on a g92b is not bad either, but i usually oc till temps are a problem. I'm not used to reach the chip limits, and the folding junkie i am just wants more!

Have you tried MSI Afterburner? That's what I use to over-volt my GTS450.

And what are your temps?

 

[Feänor]

As i'm typing, 69 on the gtx275 and 71 on the gts 250. Trying msi right now...

So i cannot change any of my 5 gpu's voltage. Tried unlocking volatge control and monitoring, no go. is there a way to know if a card's voltage regulator can be accessed by software?

I don't know, Afterburner is what I've had success with on my GTS450

Maybe EVGA has a utility? IDK really

 

[Feänor]

EVGA Precision. Been using it since last year. Got to register to download, but an official version is always welcome. Looks like i'll have to leave them where they are.

I know about EVGA Precision as well, I use it

I thought that they might have some other tool just for the CO-OP since it's a special card

had both the gtx275 co-op and the gtx 295 co-op ftw edition, both cards use the same pcb and as far as i can tell the only way to over volt them is to volt mod them. No software control was included. there might be a wayt o do it via a bios mod, but I'd imagine you'd have to be careful with 2 different, nonidentical cores
