R6EO Instability

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.

You can soak test it without adjusting the other rails, yes. Worth pointing out you can use the DRAM Boot voltage setting to increase VDIMM at POST.


As above per your recommendations. I appreciate the help from everyone.


"Worth pointing out you can use the DRAM Boot voltage setting to increase VDIMM at POST." Don't exactly understand what you mean here. Simply check the voltage in the bios?

No worries.

No, Eventual DRAM Voltage has been available for some time and should be under the Extreme Tweaker menu. This allows you to set a VDIMM value for the OS that differs from the value used at POST. The POST VDIMM value is the conventional DRAM value set. I wouldn't adjust these values now that you're stable.

Ah, thanks. That clears up my confusion. 🙂

I was wondering that myself, but it was so stable with XMP setting the values with 0218. Installed windows without any problems at all. I will tweak the VDIMM and post back. Thanks.

Hi,
At 4.9 I'm pretty sure your avx would need 4 not 3 to run any avx content like blender classroom rendering demo file successfully repeating/ looping
AVX 512 should be fine where it is.

But indeed 1.39v dimm voltage minimum which will probably output 1.4v max

Hold onto your set there with input voltage on auto
It will produce 1.2v+ where that frankly is overkill
Where 1.92v should be fine and 1.95v is a better max if needed depending on LLC used 5 is good with 1.94v

All can be monitored easily with hwinfo free in a straight forward assortment

It's a silicon lottery chip, so I'm using the recommendations for AVX that they provided.

I can say my board is completly stable with the 0504 bios. My system is all water cooled with seprate loops for video cards and cpu. Mine is overclocked i9-7980XE @ 4958 all cores and DDR4 4000 Ram oc'd to 4132. My bios settings are AI OC Tuner = XMP CPU Strap=100 BCLK Frequency = 103.3000 CPU Core Ration= Sync all @48 TPU = TPU II CPU Core Voltage= 1.4000 CPU Input Voltage = 2.000 DRAM Voltag = 1.440 I ran these same settings on my Rampage VI Extreme Apex for over a year with no issues.
