Originally posted by anarki2 View Post(I can't edit my prev comment) I also read A LOT of random complaint threads about these. The workarounds are even more staggering, like disable all CPU scaling in UEFI. Or disable PSU whatever states, I can't even remember all this random cr@p. Like we live in the year 2020 but CPU scaling still is a challenge?
Then again, that's exactly the reason why I already gave up on AMD once many many years ago.
The "PSU whatever states" actually Power Supply Idle Control is the actual firmware-level workaround for hardware bugs in first and second gen Ryzens, and it's only partially disabling C6 state, which is completely inconsequential for a desktop system.

But last year I needed to build a PC and I went for a 8700k as I needed to start working on it. Didn't have the time to skim through forums for RAM sticks that work with a specific mobo.
All the complaints are from overclockers, and they are free to whine if something can't OC as high as they wanted to, but it's never guaranteed so whatever.
You sure you know how to troll properly? Because it seems you don't.

Originally posted by caligula View PostThat's a seriously unrealistic scenario. Seriously man, I would only be expecting around 12% better throughput (DDR4-3600 vs 3200) in a synthetic memory bandwidth benchmark. The impact on CPU bound tasks might be 1-2%, while games, otoh, are often not CPU bound at all.
That the SotTR game reacts by a lot to this is also proven by others (use search machine), so perhaps keep your uneducated opinion to urself or ask kindly so that someone might explain it to you.

Originally posted by anarki2 View Post20.04 can't come soon enough, currently I'm forced to use a mix of 18.04 and some 20.04 kernel packages (5.4 as of now) via some lovely apt pinning mess, since the 3990X + Aorus B450 Pro are complete cr@p on 5.3 (that's the latest available via hwe-edge). Hard freezes like every half hour. The best part is that every time this happens it results in one of 2 things: a) it resets BIOS settings b) bluetooth is gone until I power cycle the PSU. Quite ridiculous.
Dunno what's up with this system, but it does the same even on Windows 10 1909, unless you stumble upon the latest B450 chipstet drivers directly from AMD. No, Windows Update won't install them, the Gigabyte support page does not have them. Only amd.com.
Software wise, this Zen 2 rollout sure is a mess. It's been 6 months, but we still need various quirks to make it work.
My previous Ryzen 7 1700 suffers as well from the mentioned power supply idle bug. In this case AMD should have done more to provide stable systems to their customers.
Where AMD really struggles with are APU's... I don't know why, but it took AMD really really long to get them mostly stable, just some weeks ago I suffered from GPU resets on my Ryzen 5 2500U just by starting Plasma. And the Ryzen 3 2200 had many issues as well (firmware bugs, ...).
Anyway I do buy only AMD systems as they get better over time. With Intel you can only be sure that performance decreases drastically, what was it just now, 50% for my Haswell? :-(
