Still having stability issues with bios 0504. I had installed windows with 0218 with no problems at all. CPU is by SL. I keep getting problems on cold boot. I had BD memory error 2 days ago and changed the Uncore voltage from auto to 0.200 and it crashed without getting to windows. Decreased Uncore to 0.100 and it went through Memtest 400% with no errors and, more importantly, it did not crash. I had already tested the memory outside windows with no errors. On cold boot this morning, I had another crash with Uncore at 0.100V. Machine came back up with "memory is OK, press F1 to save memory settings." I decreased Uncore to 0.050V.
Where to go from here? As I said, I installed windows with 0218 bios version and no problems.
