.1v right?? Tad da dum!!

Anyway, I had my bro buy some Buffalo DDR3200 RAM to put on his Biostar M7VIW (in case he wanted to upgrade his processor to a 200FSB in the future). I noticed after he ordered it that the "Support Voltage" listed in the specs on the Newegg web page lists it as 2.6V where other sticks are listed as 2.5v. Will the 2.6V RAM run ok on a mb that only supports 2.5V and has no voltage adjustment? He already installed the RAM and it seems to be working fine except for a few quirks with a Microsoft USB keyboard.

Any thoughts??

Run memtest 86 on it. if it checks out it is fine. i find that most MB overvolt the memory a touch anyway.

My Asus A7N8X-DX doesn't even have a 2.5V vDimm option! You should be fine and like LordOfAll said, just run memtest86 to make sure it's all good.

Check which modules are on the DIMM if it doesn't have a heatspreader. Good DDR400 and higher come with Winbond BH-5 chips, and are highly desirable for o/cing, and they are usually rated to run @ 2.6v. It should still run fine @ rated speed @ 2.5v, as long as the board gives a solid 2.5v.

Since it says Infineon chips, and it's CL3, my guess is you don't have those Winbond chips. However, you *should* be fine with 2.5v... :)
