Modding the BiOS on my msi GTX 560 Ti Twin Frozr OC card.

Post by Mystical_Titan »

Hi guys and gals.

I have two of the following card:

http://www.msi.com/product/vga/N560GTX- ... II-OC.html

They have a 880 MHz core. When I OC them, I don't reach very high clocks before running into stability issues, probably due to the SLi. What I thought of going was OCing each card indivually and modding the new clocks into the cards' BiOS. What I was also thinking was finding someone who has the SoC version and extract that card's BiOS and flash it onto mine, seeing as they're pretty much identical, except for the core clock.

Thoughts, anyone?

MSI twinfrozer 560ti should run at a clock of 850mhz if I am not mistaken.

No, they don't. The reference clock speed for the 560 Ti is 822 MHz, mine are factory OCed to 880 MHz, as shown in the link.

He's got the MSI GTX560Ti OC card - 880mhz core, 4200mhz RAM speed.

I'm surprised you're having issues with overclocking them M_T. Are you giving them a enough of a Volt bump? And are you using MSI Afterburner to OC them?

Try running one at a time and see what you can push them to?

That's what I'm doing. I'm using AfterBurner for OCing and FurMark for stability testing.

I had something really weird happen where the graphics driver crashed during a FurMark run when everything was on default settings. Once I raised the mV from 1,000 to 1,025, the problem seemed to go away. Weird.

Couldn't get one card stable at 950 MHz, so no point in trying two. They're running at 900 MHz now.
