[Solved] did I just destroy my cpu? (lemmy.world)

I tried adding 2 new RAM sticks to my computer. It was powered off, but had the power cord in (not sure if that makes a difference).

When I booted up , it didn't post, and showed the cpu debug led. I reset the CMOS, but it still shows the cpu debug led and doesn't post.

Any advice is appreciated

MSI x570-a-pro
5800x3d
32gb ram @ 3600 xmp
New 32gb ram @ 2600 xmp
6800xt

I stuck a butter knife into the CMOS battery jumper for 10s with the power off and the cord disconnected, this had no effect.

I'm worried because the debug LED is stuck on CPU, and not mem.

I have tried removing all the ram, and only using 1 stick, etc but no difference

Help me Tech support, your my only hope

Edit:

Turns out one of the RAM sticks wasn't seated properly.

I now have 64 gigs of RAM running without XMP. I'm testing this now to see if it is better for me than 32 gigs of 3600 MTS.

My use case is running and debugging SIEM software. So I feel like more fun is going to be better than faster RAM?

12% drop in Geekbench score, and no measurable improvement to the enterprise software. Will revert back to 32gb.

I believe to clear the cmos you need to boot the computer with the jumper off once.

The CPU debug led is ambiguous, could be complaining about the ram. Make sure it's seated all the way.

Which slot is your single stick of known-good memory in? Google says to use A2 if using 1 stick

[–] andy64 3 points 1 year ago (1 children)

Yes a2

[–] Arete 4 points 1 year ago (1 children)

If it were me my next step would be re-seating the cpu itself, just to rule out a physical connection issue.

[–] andy64 3 points 1 year ago (1 children)

I actually just tried with a different stick in a2 and it's now stuck on VGA, which is progress, I guess.

I'll have to pick up some new paste to try reseating the cpu next.

[–] Arete 3 points 1 year ago (1 children)

Maybe try reseating your GPU first since you have a VGA error now? No thermal paste required for that

I was able to get it working with the original two ram sticks, but trying again for the four series to have the same issue.

Oh well

[–] Arete 2 points 1 year ago (1 children)

Hey at least it still works. Are you sure the new sticks are compatible with your system? Maybe you just need a bios update?

[–] andy64 3 points 1 year ago

The sticks were old ones that I had used a few years ago before upgrading.

Turns out it was a id10t error, and I hadn't fully seated the new sticks. Not sure why that problem persisted after a removed them but oh well. It's now working.

64gigs of RAM running at a measly 2100mts. Now it's time to figure out how to get both running with xmp.

Thanks @arete for all your help

Yup.

I learned it all the way back with the Nintendo 64, more RAM ≠ more speed. (Expansion Pak)

Measure how much memory your typical workload will consume and setup your sticks accordingly.

I find myself frecquently switching the RAM configuration of my laptop between 4, 8 & 16GB of RAM just to achieve optimal performance. (And to save battery life, of course).
