Ryzen 2700 x570 2 x 8GB 3200 CL16 Now Unstable

[Gorgon]

Refreshed one of the kid’s gaming rigs back in November and things were going well until kid mentioned Blue Screens a couple of days ago.

 

Ryzen 2700 (not the X) with Wraith Prisim

Gigabyte x570 Gaming X

2 x 8GB Corsair Vengeance RGB Pro 3200 CL16 P/N CMW16GX4M2C3200C16W

DOCP enabled, All other BIOS settings at default. RAM in correct slots for Daisy Chain.

 

Benched it and stressed the CPU (BOINC) and GPU (Folding@Home) and yes it does Blue Screen consistently with a rather useless PFN_LIST_CORRUPT error which M$ says has something to do with either a bad driver or Memory.

 

Ran DDU in Safe Mode to remove all Audio & Video drivers. Re-installed Chipset, Audio & Video Drivers. No Joy - Still Blue Screened. Ran Windows Update - Up to Date. Checked the BIOS version (v12e) upgraded to latest (v33). Still no Joy.

 

Ran Memtest86 - 36 errors on first pass. Stopped, Reseated RAM, still erroring, disabled DOCP. 0 errors on first two passes, waiting for 2 more passes to finish.

 

Assuming it survives 2 more passes of Memtest86 it would appear the Memory or IMC has degraded a ‘tich since the system was built and it needs either timings and/or Voltages adjusted.

 

The plan:

 

Run Thaiphoon Burner to get Die Density and Rank

Run Ryzen DRAM Calculator to get “Fast” Timings and Voltages

Enable DOCP and season timings and voltages to suggested values

Run MemTest86 to verify

Fail - Try increasing DRAM voltage 1.35-1.45V

MemTest

Fail - Try Increasing SoC Voltage to 1.1-1.2V

MemTest

Fail - Calculate timings for 3000 and repeat.

 

Suggestions? Alternatives?

Well memtest errors basically mean the ram is bad so just rma it.

Use 2933mhz mem freq. with that processor and it should pass your testing.

Not necessarily, and as the memory isn’t on the QVL list for that motherboard and it does work at JEDEC timings I’m SOL with an RMA.

 

The RAM runs just fine on my Aorus x570 Master with my 3900x so I’m pretty certain it’s down to the Mobo and IMC in that Zen+ CPU.

That’s a last resort as I don’t want to have to drop the IFC ratio. But yeah, worst case that’s probably where I’ll end up based on other people who’ve lost the lottery with 2700s.

Well 2933mhz is the supported Cpu IMC frequency.

 

A proper set of B-die memory you probably could get more from it.

Turns out that Corsair kit is B-Die so I suspect the Memory Controller is weak on the CPU. Settled on 2933 with Primary Timings tightened to 14-16-16-16-30 from 16-18-18-18-32 on 3200.

 

Passed a quick Memtest86 run. Running it overnight now.

It could be the IMC just being finicky. Or the board too. Wouldn't know without testing the cpu in a different board I suppose.

 

B-Die with  3200mhz 16-18-18 specs? More likely Micron or Hynix.
