R6EO Instability

[Hopper64]

Still having stability issues with bios 0504. I had installed windows with 0218 with no problems at all. CPU is by SL. I keep getting problems on cold boot. I had BD memory error 2 days ago and changed the Uncore voltage from auto to 0.200 and it crashed without getting to windows. Decreased Uncore to 0.100 and it went through Memtest 400% with no errors and, more importantly, it did not crash. I had already tested the memory outside windows with no errors. On cold boot this morning, I had another crash with Uncore at 0.100V. Machine came back up with "memory is OK, press F1 to save memory settings." I decreased Uncore to 0.050V.

Where to go from here? As I said, I installed windows with 0218 bios version and no problems.

I have HWInfo as well:

Hi,
You might want to update it some of those readings can't be right lol 12v rail at 20.v.... lol 😄

Try the newest beta v6.01-3660 might straighten out some of the wildly off readings hopefully 😕

I let ramtest run a bit over 30 minutes with no crashes:

off to work. Try to tweak some tomorrow. Hope it cold boots. Thanks for all the help as always guys! I will report back.

Yea. I'll try the beta when I get back. I thought I would change one setting at a time as discussed above. I don't think changing several items at once is a good idea. Just cause confusion.

Hi,
Yep most would concur one maybe two settings at a time to see what happens is a good policy 🙂

[Hopper64]

I'm just going to keep the VDIMM settings and see how things go. Thanks again.

I do not want to confuse but I always had this warning on ASUS boards + HWINFO, for instability in the system.
In the specific case, it was the VRM TEMP

[Hopper64]

That program is not running in the background. Mine only works when I'm looking for the data. It is not active all the time.

You can also go back to 0218 and check the auto voltages for SA and IO plus the memory sub-timings. The auto values may need tuning for 64GB running at DDR4-4000.

Wish I could. I tried that first and I got the "Don't shutdown or reboot to avoid system bootup failure" message.

Frankly, I like learning to tweak these voltages anyway. 🙂
