Ryzen SOC & DRAM Voltages

[Ne0nDrag0n]

Hey everyone,

 

I'm new to the Ryzen platform and DRAM overclocking in general, so I have a few questions regarding voltages and temps here.

 

Right now I'm running:

ASRock Steel Legend x570

Ryzen 7 3700X

And this Gskill RAM: https://www.gskill.com/specification/165/326/1562839299/F4-3600C16D-16GTZN-Specification

 

I recently upgraded from a 3200CL16 kit, to this 3600CL16 kit. The 3200CL16 kit always passed memtests flawlessly. (I know the new kit is not QVL for specific model)

 

Using XMP, I can boot and run benchmarks fine, but was seeing some odd errors in Memtest86.

 

On default XMP I would fail "Test 6 Block Move" every other test. So I RMA'd the RAM and just got the replacement.

Same results.

I ran Memtest86 (and Memtest86+, the latest beta build) and only failed on the block move tests. And pretty frequently, every other pass or more.

 

Other than the RAM freq increase, the FCLK is also going from 1600 to 1800mhz. And from what I understand the Block move test is very heavy on the memory bandwidth side of things.

I started thinking I could tweak my way out of the errors, and started to manually adjust voltages.

 

I started to see less and less memtest errors with each bump in voltage on the DRAM and SOC. Now I've passed 12 block move tests in a row, when before I couldn't pass more than 1 consecutively.

 

I'm not 100% that this isn't still bad memory but it seems like I've got better results (passing 3 tests at a time, then 4 or 5, then 7 or 8, now 12).

 

At this point I felt comfortable booting to Windows and have gone through the Ryzen DRAM Calc's memtest, and a Cinebench R20 run without issue.

 

Now, I want to make sure what I have set for voltages isn't going to fry my system before running a longer 24h prime and memtest86 runs.

 

I currently have, set in bios:

VDDCR SOC: 1.181

CLDO VDDP: 1.010

CLDO VDDG: .780

DRAM: 1.395

 

Seems like the motherboard here likes to over/undervolt slightly, so in Windows with HWiNFO I'm reading:

SOC: 1.194

VDDP: 1.0094

VDDG: 0.7793

DRAM: 1.408

 

From what I understand, I'm almost at max SOC, but I think DRAM is OK.

 

And now for the questions.

#1 Is this in vain? Should I just RMA the memory for a second time?

#2 Is this SOC voltage too high for 24/7 use/uptime?

#3 Under short prime95 memory runs (1h, large ffts) I'm seeing 45c stabilize on the DIMM slots. Is this too high?

 

TIA!!!
