I have an E8400 from a rather poor batch (3.6GHz @ 1.22v yet anything higher like 3.8GHz or 4GHz requires huge doses of voltage) and am still using bios 308. Is there any risk from using bios 308 since it maxes out tREF? System is stable but I'm convinced that a tREF of 16383 on DDR2 800 is somehow going to cause problems for me in the future. Will my stubborn C0 E8400 failbatch benefit from flashing to the newer bios versions?
