Just fired up my Z97 Extreme6/4790K system running under W8.1 Update 1 and have a few issues. The MB came with P1.20 BIOS and was working quite well but the 4790K would only run at X42 when executing Prime95 or IBT. It seem to touch X44 for a moment or two when starting other programs. So, I went looking for the latest BIOS thinking that would fix the X42 issue. I did the Instant Flash routine from the BIOS and it updated the MB to P1.33 with no problems. However, now when I boot the system goes into some sort of a trance for ~20 seconds and most of the desktop icons are blank. At the end of the 20 second "delay" Windows repaints the desktop with all the icons. I then ran Prime95 and IBT and they still only run at X42!
I guess I'm on the @#$% bleeding edge again - has anybody else had a similar experience with P1.33? I've checked the Event Log and nothing is out of the ordinary and the system runs just fine after the desktop repaints. Is it possible to back off the BIOS to an older version? Any suggestion on which version is the most stable. Or can I go to the backup BIOS on the MB and see if the problem goes away? I got spoiled with the Gigabyte MB's that let you play with two BIOS versions.
And then there is the X42 issue - What am I missing that causes the CPU to be limited under load? I have left all the BIOS settings at the defaults except the Memory which is set to Profile
Oops, Don't know why or how updating the BIOS could have caused the problem to surface but I uninstalled EaseUS Backup because it would not run on the new system and the ~20 second icon problem disappeared! So now I'm back to only the original issue the X42 limit when the CPU is under load.
