3950X is my favorite Processor and my current development workstation, paired with a dual memory kit

This kit of four 8GB DIMM is a very instructive case as the IMC here shows different size and geometry results.

The issue is now to fix decoding of 4 DIMMs layout.

giganode commented 3 years ago

Thank you btw @cyring !!!

Keep up your good work!

Hello,

To debug this 4 sticks setup, can you run my following user-space code.

  1. Download zencli.c
  2. Compile 
    cc zencli.c -o zencli
  3. Execute UMC (as root) 
    zencli umc

@ich777 @giganode EVRY1

Please I need your help with the above request https://github.com/cyring/CoreFreq/issues/258#issuecomment-865681047 to debug the 4 x DIMMs issue on Zen/UMC

Thank you

ich777 commented 3 years ago

@cyring sorry for the delay. Will compile it today evening and send it out to @giganode so that he can test it.

EDIT: everything compiled and sent to @giganode he will post the output here.

@giganode Thanks a lot ! Can you tell about your DIMM setup : how much do you have of them physically ? dmidecode -t memory will be fine

EDIT: sorry, just noticed it was provided in https://github.com/cyring/CoreFreq/issues/258#issue-925640285

giganode commented 3 years ago

@cyring no problem!!! Does the provided data help you?

cyring commented 3 years ago

@cyring no problem!!! Does the provided data help you?

Yes, thank you.

I'm now not sure about an obvious discriminant between the 4 DIMM and the 2 DIMM dumps ! In both cases, we have two enabled chips per DIMM

The difference with your DIMM case is the following:

CHA[1] CHIP[1:0] @ 0x00150004[0x00000000] Disable, Rank=2
CHA[1] MASK[1:0] @ 0x00150020[0x03fffdfe]

where bit position zero is clear thus chip is disabled but we however have a size of 0x03fffdfe

I met that case with a 2700X where ignoring that zero bit lead to a wrong DIMM size.

cyring commented 3 years ago

EDIT: I will refactor the whole algorithm. I think bits are probably CHIP/DiMM populated

For example: addr[val] 0x00150008[0x00000201] in binary 0000 0010 0000 0001

One populated slot in each group of 8

Has Zen architecture a max of 8 DIMMs per channel ? Like EPYC.

Hey, saw this at random and figured I'd be useful for once and leave some data. 3950X on X570 Aorus Pro, 4x8GB Samsung B-Dies (F4-3200C15D-16GVK)
