So, one of the modules in one of my DDR5 kits decided to stop working. It’s no longer detected in either Windows or the BIOS no matter the RAM slot. I tried it in multiple motherboards too. Still not detected. It’s outside of the return window, so what do I do? Request an RMA.

I went to G.SKILL’s website, found a dedicated RMA page, filled out my info, and now I’ve got an RMA in progress. No questions asked, and no user account creation necessary. Why can’t other companies be as easy as this to RMA their products? Now, I don’t know if G.SKILL just takes everyone’s word that RAM is dead or if they test it once received, but how they go about their warranty/RMA service is top notch.

Just throwing this out there. I’ve had to RMA Corsair RAM before, and they usually have no qualms about it. However, I still needed a user account and to open a ticket first, then wait for replies before an RMA was started. Bottom line: I think I’m sticking with G.SKILL from now on.

I'll add their great service & tech support, before & after the sale
 
G.Skill is always my choice in RAM

So, the dead RAM module may be part of a bigger problem. One of the RAM slots on the motherboard that kit was in is no longer working. I’m now questioning the PSU since it’s around 8 years old, and maybe it’s no longer supplying correct voltages. Just a theory. The build in question has hardly been used or even plugged in, for the matter, since I first got the RAM and motherboard, which an Asus Prime Z690-A, as part of a Newegg combo on the 7th of December. I’m talking a grand total of maybe a few hours worth of usage since getting the components. Why only a few hours? I thought the 12700K I was using was bad, so I exchanged it but it took a few weeks for me to be able to do that. The system was working okay for a short while with the new 12700K before I started getting system freezes and shutdowns. Bad RAM slot, bad RAM module, and a bad CPU? If anyone’s got a better theory other than the PSU, please let me know. It a Corsair HX1000i.
