Yes, we had got 6 AMD first gen Ryzen CPUs at my old job. Some of them were super instable on Linux. I tried a few magic solution and tricks but they always crashed eventually.
In my new job, I have a co-worker who is an AMD fan boy. He also had a first gen Razen CPU on his workstation. He got an Intel CPU after one crash and everything is fine since. He is still upset about it. Though he got a new Ryzen CPU at home and he says it's stable.
- maallooc 7y agoPeople doing real jobs with their computers know this.
- hddherman 7y agoI assume that you got hit by the issue that was present in the early 1st gen Ryzen CPU-s. It did get resolved later on and AMD started a replacement program to address that particular issue.
- speedgoose 7y agoYes I think so.
- eatthoselemons 7y agoWhat issues have you had on the first Gen ryzen cpus? I have been running 6 of them on my home lab (true a small sample size) and I have had no issues with them
- speedgoose 7y agoSome were stable. Some were crashing after a random amount of time. Usually days. No kernel panic, just nothing. It didn't depend on the load, and whatever option you put on the kernel. We changed power supply and ram, and we eventually gave up.
- rooam-dev 7y agoAre they still unstable? Was it the hardware or software the problem (bad support on Linux)?
- speedgoose 7y agoI changed job since. I guess they still crash or have been disposed. I think it was both hardware and software, since some were working well and the crashing ones were working better on Windows.
- SomeoneFromCA 7y agoAFAIR 1st Ryzens had some issues with their memory controllers.
- dragontamer 7y ago1st gen Ryzen had a poor memory controller that was very finicky with memory. I had to swap out RAM a few times to get my 1st Gen Ryzen stable, but it's been rock solid since then. CPU / Motherboard compatibility with RAM is hard. IIRC, there was a brief 2nd gen Ryzen glitch for crashing, which was resolved with some BIOS updates.
- washadjeffmad 7y agoI've repurposed a R5 1600AE in a FreeBSD storage server, and I was frustrated by near-daily lockups after running it stably for the past few years on Linux. After a BIOS update, an option for power supply idle control appeared, and selecting the "typical" over "low" option resolved the hangups. No C-state or C'n'Q changes required. I did have to RMA the CPU initially when it wouldn't post with DIMMs in 2/4 slots, but later revisions seem to have quickly overcome the memory controller issues.
