no prob, bob

You have to flash the second one using the oc.rom file from the first page (in dos). Then use nvidia inspector to overclock both cards. You select which card to chane the values for at the bottom in inspector. When done setting make sure you press apply clock values and voltages then for each card right click set startup shortcut and create one for each. Make sure you do this for both cards or when you restart the values will revert back to normal!

For me, the perfect balance between temp and performance seems to be 1100 shader and 2500 memory. The max temp I hit on either card is 75 under full load (gt650m has max op temp of 105). Thanks again to svl7 (and zedster for getting me the needed bios link)!

Nevermind - zedster sent me the link I needed! Thanks zed!

So where is the modded BIOS file you use for flashing? The zip file only has a small 46kb file in it to use with the second GPU. Sorry if this is a dumb question - - - Updated - - - What I'm asking is where do I find the file to use when YBIOSFix asks for modded BIOS file to use?

I backed my BIOS up, but every time I try to run YBIOSFix, it gives me the error: "ERROR - Modified BIOS is invalid". I've shortened it to less than 8 chars, but no luck : /

Don't tell me it's not gonna work! I paid for a subscription just to get the files needed : / - - - Updated - - - Any ideas? Could someone maybe send me a copy of the file that worked for them?

Still giving me the same error Am I supposed to be using the ROM file from Y500 - Y400 - SLI 650m - 80.07.27.00.33 - OC.ROM.zip for the first GPU (I have sli)? If not, I can't seem to find the modded bios for the first gpu.

I tried using the rom file and it says "ERROR - Modified BIOS file is invalid. Press enter to exit."

I'm confused. I'm following the instructions, but the v2.02 doesn't have a .bin file in it, only a .ROM file, which the fix tool won't accept.
