I’m not sure this is a write section but I will try.
I’m angry at myself that I should’ve bought a UD7 Rev.1 and i7-920 instead (which can run on lower voltages/temperatures – Vcore/1.27500V VTT/1.255V) to avoid this nightmare.
Below are my settings which I have done some tests with different adjustments on lower voltages. Under Prime95 system is stable, under normal usage or games system is also stable.
I installed latest chipset driver (over the top). I couldn’t find how to uninstall old ones. Can you please advice proper installation of the chipset drivers?
The system was shut down for 12hrs (each day). Cold boot O.K.
Computer switched off for 24Hhrs. Cold boot problem.
Tested with CorsAir CMG6GX3M3A 1866C7 - Still the same problem.
a. Temperatures under Prime95 (when case is closed and under the desk) 85 84 82 80
b. Temperatures under Prime95 (when case is opened and out of the desk, more space) 80 77 76 74
c. But the same problem exists – cold boot problem after 20 minutes or 12hrs or 24 hrs. Not always but most of the time.
d. Under X.M.P. profile 3.02GHz running and booting normally.
What is the best BIOS version for X58-UD7 Rev. 2. Please advise.
Any help appreciated.
P. S. This is not all of it because I exceeded the maximum amount of characters in this post and I couldn't attach the word document to this post because it is larger than 150KB (maximum size to attach) any Idea how I can give you the file?
