I figured out the issue, it just needed a bios update. Which is odd cause it was posting with the older version. I guess the newer one fixed stability.

Specs: R7 2700, 16gb 3200 Corsair Vengeance Pro, B450-F Asus Strix, GTX 970, Corsair 650w PSU Recently decided to finish up a Ryzen build I've put off for years. Got all the components I needed, did the usual set up outside of case yada yada. Here is where the issues arose. Couldn't short the pins to start up, or start with a button, tested every component aside from CPU on a different platform board/chip, all work, return board. New board comes in, install everything, 1st problem DRAM led, after making sure all the ports are clean, that fixes the issue. After that, I get VGA Led, so at this point I feel like something is wrong with the CPU because the GPU I know for a fact is working. After some tinkering around, I discover it will Post only when I initially install the CPU, but if I have to restart the system for any reason, it will not post again, and the VGA LED will light up again. I have tested this theory many times and every time I remove the CPU and reinstall it, it posts. Most of the time you hear people not booting on first start up so I'm stumped. This is an issue because I haven't installed windows so I can't just put it into sleep mode which I'm not sure if it would turn back on after that. And if in the future I need to restart for any reason, I don't want to have to take out CPU and put it back it every time. PROOF THAT IT POSTS So not sure if this is a CPU issue or Board issue, I've ordered another CPU to test with but won't get here for another week. Any suggestion or help is appreciated!

I figured, i tried everything I could think of but thought I'd ask more knowledgeable people. I'm fine with 3 cores anyways since its only gonna be used as a word processing/browsing PC. Thanks

He had it overclocked, but I've reverted everything to default. And he said the problem was present when he first got the CPU.

So recently purchased a used mobo-ram-cpu combo for a build. The seller told me the CPU won't work unless a core is disabled and couldn't tell me for sure why this was the case. I was just wondering if anyone here had any suggestions on possibly fixing this or if I'm stuck with running it at 3 cores. Cheers!
