I realize that there are many guides to overclocking the GTX260 out there. Heck, there are even guides to overclocking SLI'd 260s. However, I haven't been able to stumble upon a guide pertaining to overclocking an SLI configuration of one Core 192 and one Core 216. As such, I have no idea where to start. Any advice, direction, or instruction would be deeply appreciated.


Prevalent info (As indicated by Everest Ultimate edition):
Motherboard:
ASRock K10N780SLIX3-WiFi

Chipset:
North Bridge: AMD K10 IMC
South Bridge: nVIDIA nForce 780a SLI (MCP72XE)

Graphics cards:
GPU 1 (core216): PCI Express 2.0 x16: XFX GeForce GTX 260
GPU Clock (Geometric Domain) 576 MHz (original: 576 MHz)
GPU Clock (Shader Domain) 1242 MHz (original: 1242 MHz)

GPU 2 (core192): PCI Express 2.0 x16: MSI nVIDIA GeForce GTX 260 (p651)
GPU Clock (Geometric Domain) 301 MHz (original: 620 MHz)
GPU Clock (Shader Domain) 602 MHz (original: 1296 MHz)

*GPU1 is idling at 53 C and GPU2 is idling at 45 C under current settings and clocks.

PS. I don't know why the clocks for GPU 2 (core 192 one) is cut in half, it's very odd. I believe it's just doing that for power saving purposes, because when I open up a game, the clocks go back up to default levels again. Anyways, I confirmed these data with GPU-Z just incase Everest was inaccurate.


If you need any more information not included here please, by all means, feel free to ask. I will post it up as promptly as possible. Again, thanks so much for your help.

Well, my 1st step will be OC the 192 GPU 'till the default settings of the 216 GPU.

After that, you can try with the process of this article.

Wow, I didn't know you could SLI a 260 with 192sp with one that has 216sp. Yeah the clocks are lowered when it's idle, tho it seems that the first GPU is not down clocking itself when idle. Anyway, yeah follow saint's advice there :D .

Do you mean underclock? Because right now, it seems like that 192 GPU's clocks are factory overclocked above the 216's (when not idled).

^Yeah, that's is a better way.

Underclock your GTX260 core 216 at the default setting os the GTX260 core 192. That I think are 620/1296/1080...

Should I use the Performance settings under Nvidia Control Panel to do this or do you recommend some other 3rd party software like Rivatuner?

Yeah, is better use RivaTuner to do that, sometimes the nVidia control panel isn't good for OC or Underclock
