Hey everyone!
A bit of backstory, I just switched to AMD and picked myself up a Ryzen 7 3700x, ASUS ROG STRIX B-450F and 32GB (4x8GB) Corsair Vengeance Pro 3200Mhz after being with Intel since the start of my computer building escapades. After some initial teething problems (caused by thinking the RAM would use the XMP profile straight away with no tinkering required) I managed to get everything up and running and was loving it. I had left it running Friday night generating thumbnails for Plex and it was still working at this up until Tuesday evening when I noticed the server had went offline, I thought maybe my power had went out or my powerline adapter had messed up, but when I returned home Wednesday morning the computer fans and lights were all spinning but no display. I turned it off and on again but no post, the DRAM light was lit up on the board so I assumed it was a RAM issue. Luckily my brother also runs a Ryzen build so I was able to start troubleshooting, I swapped out every part to no success until I had only the CPU left, I put his Ryzen 3 1300x in my build and it booted up straight away into Windows, all 32GB RAM recognized and everything running as normal. Tried my CPU in his build and the exact same issue, no post.
I have a replacement CPU arriving tomorrow so I'm really just looking for some knowledge on what could have caused this, was I just unlucky and got a faulty CPU? Some points of interest:
- I know the B450-F isn't considered a great board for overclocking, I don't OC whatsoever and everything was left at Auto, apart from the RAM which was set to run at 2933Mhz. Memtest64 comfirmed this stable. Surely the board would be fine for handling a 3700x at stock speeds?
- I've read that AMD boards sometimes aggressively overclock Ryzen CPU's to get the most out of them, causing the CPU Voltage to go dangerously high, could this have caused the CPU to fail? Should I set the board to run at a constant voltage when I get the replacement?
- Temps were idling around 40C, hotter than what I'm used to with my Intel build but I think Ryzen just runs hotter? Also using the stock Prism cooler, I had an aftermarket one on the Intel build so this could have changed things. I'm assuming if the CPU got dangerously hot the board would have protections built in to stop this.
Any help or insights would be greatly appreciated!
