Likelihood of replaced RAM being faulty too?

[Jwoo32]

Hello,

A few months ago I had some issues with a new Ryzen build. Random crashes in games, after a lot of troubleshooting I think one of the RAM sticks was faulty. No errors in Memtest but failed AIDA64's stability test in seconds. One of the sticks worked absolutely fine.

(2x4GB)


Sent both sticks (as required) off to Corsair RMA, Tried the replacement and getting similar issues to returned sticks. "Kernel security check failure" installing Windows, AIDA64 stability test failing within seconds. Now also getting weird corruption in Mail - https://i.imgur.com/lHFDGvH.png

Can't be GPU as I bought a new GPU when I was troubleshooting the first lot of RAM. Corruption in Mail is new, but there were weird graphic issues with the first faulty stick of RAM.

The second stick doesn't seem to boot. Computer just sits in an endless boot loop, rebooting every 10 seconds, with no output to the screen whatsoever.

I was wondering how likely it is that the replacements Corsair sent are also faulty?

Does the stick that doesn't boot also fail to boot in any of the memory sockets on the board?

Tried increasing memory voltage a little?

Tried inputting the timings/voltage manually rather than relying on XMP?

Tried slightly slower timings?

There are a lot of variables to rule out here, but a methodical approach may give you an insight into what the problem might be

Well first I tried both sticks and the system failed to boot, fell into the endless reboot cycle.

Ram in A1 and B1.

Doesn't boot when I tried it on its own in A1 but the other stick does boot when I put that one in A1.

Not really tried with timings, etc as I'm a bit of a noob to that and most of the option seems to have been removed in the most recent BIOS update (Asrock Fatality X370).

Don't see the BIOS when both ram sticks are in as it just keeps rebooting without outputting to the screen. Not sure how I could tweak figures as I don't see the BIOS with the RAM in.

Should note I tried the first lot of faulty RAM in another motherboard and it produced the same results.

It sounds to be like the memory controller is failing. It's very possible that the one stick that works is an exceptional stick and the one that fails is just normal. Increasing the RAM voltage a little may well firm up the data coming from the RAM which may cure the issue - for now, but I am afraid that if it is the case then nothing will stop it eventually failing. Offhand I have no idea whether your memory controller is in the CPU or on your motherboard.
I am confused, however that the RAM failed in the other board. It is possible that something has damaged both the RAM and the controller? Dunno but I would try raising the voltage a little just to see what happens. You can tweak the settings with the other ram in place.

Thanks for the suggestions.

Seems the replacement RAM was faulty also.

Corsair sent a second replacement, this time changing my Vengence LPX and sent me Dominator Platinum. Working now without a fault.
