Did I Buy a Burned Out CPU? (lemmy.world)

Hey all,

I took a gamble on a "for parts" 5800x3d that had a few bent pins. I currently have a 5600x with an ASUS TUF x570-Plus WiFi and thought this would be a nice upgrade.

The problem I'm seeing, is that the system won't post with the 5800 and hangs with the orange/yellow DRAM LED on the motherboard.

I thought to update the BIOS with the old CPU, but I already had a version that would support the new one. After that, I tried swapping RAM modules and only using one, then the other. Eventually I updated the BIOS to the most recent version and resetting with the jumper, but it still won't post.

Looking at the pin layout and considering the bent pins were all in one corner, I am wondering if the original owner tried to install this CPU rotated 90° and delivered some high power where it shouldn't've gone.

Any fun ideas, or did I just pay for a nice learning experience?

fixing pins is not easy (as you may well know). Installing the CPU wrong AND powering it up in that way seems almost impossible, so unless you know for sure that's what happened, I would still put my money on: "getting the pins back to perfection should make it post" maybe one of the pins that you bent back has a bad contact point with the cpu and needs to be repinned. I check out Northrigde repair videoblog sometimes, and repinning looks really, pretty hardcore so, suit up if you're going this route.

Also, to get some perspective:

Did any one of us here ever kill a CPU? I mean bent pins can happen to any nervous hardware installer, but maybe by pushing it beyond it's limits with overclocking? I have had a bit of fun with CPU's but none of them died on me.

I don't really understand how a CPU can be sold "for parts" as it's not like you can realistically take it apart, test and replace the damaged components.

If you bought it on eBay, I know that the term would have been "not working/for parts only".

Unfortunately, it seems that you took a gamble and lost.

Sounds like you paid for a learning experience. If you bent the pound back, got it to fit in the socket, and it doesn't work then there's not really anything else to do. This is assuming your MB actually supports the CPU.

Just checked Asus' support page and it does. Oddly enough, it lacks information on what RAM it supports.

If it's like any of its competitors, it's probably up to 3200 M/Ts officially and 3600+ unofficially. The QVL still sometimes has models that don't work correctly at the XMP speeds provided, so that's more of a rule of thumb anyway.

If you've straightened the pins, I'm out of ideas. I'd just be glad it didn't zap my motherboard somehow.

Look at the CPU specification, and see what the bent pins are connected to. If it's a memory controller try using a different memory controller.

You definitely paid for a learning experience, you might get super duper lucky and find some way to use the CPU. If you want extra hardcore experience, you can try to repin the CPU, but that's a long shot
