From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

AMD Zen3 Linux compatibility upgrade question (lemmy.ml)

I'm considering upgrading to a Ryzen 5 5600, they've finally come down to $100 locally (tray version sans cooler).

currently, I have a 1600AF (lower binned 2600, so Zen+) on a B450 board. the upgrade should be straightforward, my board supports it (latest BIOS) and it has the same power rating, so my cheap-ass PSU and stock cooler don't need upgrading.

reason I want to upgrade is I have a number of issues with it under linux so I'd like to check if someone runs a similar setup.

first, I have Cool & Quiet and C-states disabled and Power Idle Control to "Typical Current Idle"; otherwise the machine freezes when waking from suspend after a short while. the second issue is, I have 3600 MT/s Kingston Hyper-X modules that I have to run at 2400 because both XMP profiles (XMP1-3000 and XMP2-3600) are unstable and cause apps to crash (the latter sometimes won't boot at all, can't unlock LUKS).

supposedly, both those issues are fixed in newer gens; old Zen/Zen+ had issues with faster RAM, and the C-state handling is also better in Zen3. also, I can use the new amd-pstate driver.

my PC is plenty fast as is, I'm only considering upgrading to fix them two issues. if it's the same on the other side of the fence, I'd rather skip it.

anyone had first-hand experiences with this?

edit: thanks everyone who took the time to share their setup, I'm way more optimistic about making the jump!

For me a 5600 in a B4500 board works perfecly.

thanks for taking the time to reply. can you expand on the issues I mentioned, did you have to change those BIOS settings and does suspend/resume work? what's your RAM speed?

[–] [email protected] 4 points 7 months ago

Suspend and resume work fine. My BIOS settings are basicly stock exept for enabling XMP. My RAM is 4x8GB 3200MHz and im able to run it at full speed.

You can always take a look at https://linux-hardware.org

It is a collection of user reported systems. So you can filter for your cpu, high speed ram and look which kernel versions it works with.

The ui/ux is a bit shotty, but you'll get the hang of it after a while.
