Ok, did 5 runs at each module and no errors, however i saw something else - sticker on my ram says 9-9-9-24 and my bios sets default timing for them at 7-7-7-20. I did change them in bios to 9-9-9-24 but when i load Windows, open Everest, timing for my ram is shown as (7-7-7-20 @ 533 Mhz) (6-6-6-18 @ 457 Mhz).
Any idea why and is there a possibility that even if memtes didnt show any errors, those blue screens could be done due to that timing?
