Not personally, but it seems common on these forums. Most of the time (if it is indeed memory related), an increase in volts fixes the problem (unless the memory is faulty). I was just in my bios earlier resetting everything (as I flashed my bios), but even though I changed the DDR voltage setting I dont remember what it was called LOL! Must have been on auto pilot.
What motherboard are you using? The best thing to do is look in the motherboard manual under the bios section, and look for the DDR2 referece voltage bit. Or tell us your motherboard model and I/someone else will be able to find out where it is in your bios on an online manual.
