Wow, old. What happened at XS?

Using Google I could not find a voltage-unlocked BIOS anywhere for a GTX 560 so I edited mine with NiBiTor.

This is a BIOS for "EVGA GeForce GTX 560 2GB Superclocked +55Mhz", 865MHz/2004Mhz (Best Buy exclusive, part 02G-P3-2069-KB):

voltage is unlocked 1.212v

download (?)

Included with the ROM is another identical one saved without checksum in NiBiTor, cause maybe that matters.

1. I only got +50Mhz from this. The card previously maxed at 1.087v 920MHz (100% fan speed), and now is at 1.120v 970Mhz (Auto fan). More voltage doesn't seem to do anything, or maybe it actually increases the rate of artifacts from my testing, not sure. Whatever, 970Mhz is the wall on this card.

2. There is no change to the limit on memory voltage and didn't know where to look for that value. If your memory clock is limited to ~2405MHz then use NVInspector to set up to 3000Mhz. My card can reach 2480 before obvious artifacting, or 2288 stable.

3. If you use more than 1.087v and don't have a custom fan profile then you should set a manual fan speed beyond 75%, because the automatic speed on this card doesn't go beyond that until ~85C.

4. I don't know if anyone here does their video card shopping at Best Buy. Mine was NIB from Craigslist.
