Debug code "D2" z77x UD5H

[justingiang]

Hi ! I'm currently using z77x UD5H with F16 mod 10.
PC is stable for few days, then it suddenly freeze. when I look at the debug LED, it is "D2". I checked the manual, D2 is PCH initialization error.
Googled it, so far I can't find the cause of this problem.
It would be nice if someone knows and help me !

Did you test RAM with Memtest86+....?
Are you on stock or set XMP in BIOS (for RAM)?

i did run memtest but for 3 hrs, i dont know if that is enough
set XMP profile in bios

Re: Debug code "D2" z77x UD5H

Instead of XMP,try to set manually......seems some RAM voltages (or other) is to low.

the label on RAM said it can run at 9 - 11 - 9 -27 1.5v, but the XMP profile set them RAM at 9 - 11 - 10 - 27 1.5v.

when I set it 9 11 9 27 in the BIOS, and testing it with intel burn test, it gives me fault results.

so i have to use the XMP profile.

Re: Debug code "D2" z77x UD5H

You didn't mention whether this problem existed on previous BIOS versions. I bring it up because I had system crashes with F16 mod 10. I flashed back to F16 mod 6 and the problem went away.
