Z370 Extreme4 XMP bug

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Just wanted to mention I just updated to the the new bios they just put up (3.60) which claims to have updated some RAM compatibility. Unfortunately it didn't fix the issues (including the incorrect xmp settings that it attempts).

	Hi. You send a ticket to Asrock support? Why you expect to change anything by posting on forums?

	Many thanks to Flode, his solution worked a charm. My system: 8700k Asrock Extreme 4 Z370 2x8GB G.Skill Trident Z 3000mhz I was getting persistent corruption on my SSD and mechanical drives when XMP was enabled and CPU at 5ghz. This could be solved by turning off the CPU OC or turning off XMP. Flode's solution allows me to be stable at that configuration with the dram at 1.35v as per XMP. Now I am running it at 3200mhz stable with only a little extra dram voltage.

	Just to update, I was still getting the occasional chkdsk error even at default XMP settings (3000MHz) using Flode's values. Since the RAM tested fine after 11 memtest86 passes on another system I decided to fix the voltages to default (Flode's values are still higher than default) So far have had better luck with the VCCSA at 1.050v and VCCIO at 0.950v (default non-XMP values) I don't understand why ASROCK isn't looking into this issue since it affects everyone who buys RAM rated over 2400 MHz?

	Hello In my case I could get stability by disabling XMP profile and I set frequency (3000MHz) and primary timings manually. I found timings values in SPD section of cpu-z. Maybe this solution will be helpful for someone else.

	Hi all, Just bought a Z370 Extreme4 when I found this thread and info around the web about this. Is it fixed now?
