Installing RAM issues - adding 2 Samsung 128GB for total 512GB what correct slots(I have 8 total slots)ASUS pro ws wrx80

[Linas]

ASUS pro ws wrx80 mother board has 8 RAM slots

I had 2 SAMSUNG 128GB M386AAG40AM3-CWE Quad-Rank, DDR4 3200MHz, CL22, ECC Load Reduced Memory

I bought 2 more SAMSUNG 128GB M386AAG40AM3-CWE

Installed it and it shows up but PC restarts after 5, 10 minutes running high memory application

I checked in Command Prompt and it shows all 4 modules but under DeviceLocator it shows Dimm 0

Did I installed it in incorrect slots?

Hi Linas

Can you check the IPMI event log? DId you enable some watchdog in Bios by any chance?

@Linas

Did I installed it in incorrect slots?

Normally I’d suggest that you check the motherboard manual. But from a quick look online I can’t see the DIMM priority listed anywhere in the manual for this board.

Other than that try removing and reseating the modules.

Just wondering how you went about selecting M386AAG40AM3-CWE as ASUS doesn’t have any 128GB LRDIMMs listed in their QVL list?

[Linas]

Thats true, in manual it does not give order. It is 8 channel RAM so no to many people know how.

does this makes sense(putting all 4 Ram modules on one side)?
How do I check if my RAM is in dual mode?

My EPYC board has the slots numbered/lettered exactly the same, and the manual says to use A/B/G/H for 4 DIMMS - considering TR PRO is basically an EPYC, worth a shot?

[Linas]

I installed in C,D and H,G slops, it appears working but now some heavy load apps making pc crash. Checked on CPUz appears it recognizes

should I do A B G H or A B C D - can any program check if they installed corectly(like CPU z - what I am looking for?)

Running Wimdows 11 memory check for the last 6 hours… still at 33%

Are these good?

[GigaBusterEXE]

What’s the behavior if you set it to 3000mhz

[Linas]

Thats good suggestion

I have been testing RAM using mem86 pro. When I have 4 modules in it had errors when I tested separatelly no errors. Should I reduce RAM speed from 3200 to 3133 to make it more stable? Try other slots(I have 4 ram sticks and 8 ram slots)?

[Linas]

dropped to 3133 and still error

[GigaBusterEXE]

Try dropping it a bit more to 3000
Even though it’s load reduced dimms it can still be a lot of your memory controller didn’t win the silicon lottery

[Linas]

I changed setting in bios for 3000 but after that the system did not start, reset cmos it started. Can I check what RAM frequency in Aida64 or cpuz?

[GigaBusterEXE]

Yeah in CPUz for sure

Sometimes it can take a while to start when you change ram speed, it has to re train the ram timings to the new speed
Wrx80 especially takes a while

[Linas]

Could it be heat issues under high load my cpu at 63C and runs heavy load for hours? Add more fans?

[Linas]

Of course this temperature is with front door open and sides removed on my Fractal Define 7XL case. With everything closed it would be higher. What temperature I should be worry about?
