PC Boot Issue

[Lee]

Hi, looking for some sense checks on what I've done. I build a PC for a friend around 6 months ago (Ryzen 5 3600, MSI Mortar B450M, 2 x 8GB Teamgroup Vulcan T-Force 3200Mhz C16 with a RX590 vga card).

About a week ago whilst playing Overwatch machine crashed with BSOD, and then would not POST.

I've had a look at it today and it stop on the memory check according to the debug LED. I have then done the following:

Reset BIOS (removed CMOS battery for 20 mins) - No change
Re-seated RAM and power cables - No change
Pulled machine down to minimum spec (1 DIMM, no vga card, no SSD) - Machine passes POST and boots
Same test again with other memory DIMM, will not post
Same test with both memory DIMM's, will not post
Swapped DIMMs over, will not POST
Connected everything together with the "good" DIMM, passes POST and boots
Installed known good 2 x DDR4 DIMMs from my own machine, passes POST and boots

It boots every time with the "good" DIMM and fails to boot every time with the "bad" DIMM installed (whether on it's own or installed as a pair).

I'm thinking we have a failed DIMM. Would you agree ?

Thanks in advance,

Lee

Sounds like you've done a thorough enough test to confirm it's bad.

You know one stick is good, you know both slots are good. That's all she wrote really.

Thanks man, just looking for assurance I've not missed something obvious......RAM doesn't fail very often....

cheers

Ram doesn’t fail often and they are fairly resilient as well unless you are cranking 1.4-1.5 volts through these DDR4 and resulting in degradation

however some of the new 5100 ram by default works at 1.4v I think which is kinda high.

many way did you do memtest when the system was put together initially?

No I didn't run memtest originally. Just enabled XMP and ran some quick system stability tests.
