How do most of you set your memory timings? Im using a Asus Dark Hero with a 5900x and this ram
What tool do most of you use or are you just manually adjusting your timings? When I set the DOCP I get constant 40 post codes.

Just wanted to share a very frustrating anecdote with my 5950X build

I bought the CPU and an H110i cooler but then the PSU is tripping.
Eventually it fried the RGB on my H110.
I switched to my H100 and after switching the connectors it somehow worked.

But it crashes and hangs on Windows regularly. Well I blamed AMD GPU drivers for those.
Then NVMe drives start having issues, I get WHEAs during long disk operations on Windows, usually when exporting VMs to OVA
Then I bought a B550 board after blaming X570 instability
It worked for a while no WHEAs but when I started heavy work again it came.

So I blamed my RX5700 when the crashes came when running stuff using PlaidML, so I swapped in my RX480, it worked for a while.
Then the crashes came again, so I bought a 6600XT it worked for a while then it start crashing again
I switched the DP cables and bought the most expensive cables I saw on Amazon for my two monitors
So I blamed the Intel NVMes and Samsung NVMEs bought new SATA SSD, got WHEAs


Finally I got some time these few weeks and took out the Platinum Seasonic PSU and replaced it a cheap Cooler Master PSU.
Never had WHEA again for a quite a while

Strangely on Linux the system is much more stable, so I never thought it was the PSU.
Crashes during a long VM export of 2 hours is extremely annoying
I never did a stress, test unfortunately. The moment I put the parts together I am busy installing a long list of software on Windows and all the myriad of PPAs on Linux I don't wanna run any tests
It was a lot of hair pulling over a period of time on Windows with a lot of cursing about the pathetic stability of windows :|

I don't know what I was thinking, I was ready to replace so many things but not install some stability tests software and run them because I was worried about the "golden" packages that I replicated from my Zen2 system
In the meanwhile my Zen2 system running Linux has rebooted only twice or thrice. It was never shutdown at any point in time since I got my 5950X.

TLDR:
Even Best components from the reputable brands can fail, in my case unexpectedly a PSU
Run some stress test after assembly.

Yeah, stress tests are sanity tests. Later you'll never want to go down the rabbit hole of debugging your whole system to pin down the source of instabilities anyway, so better be safe right after assembly than sorry.

Ryzen dram calculator to start as a base profile. Then I've continued to modify them based on other recommendations and settings I've seen some from others with the same memory modules.

However getting Post issues with DOCP settings and nothing else tweaked is not a good sign.

So what a shocker :innocent:

MS has a "new" OS launching at the same time as Alder Lake with scheduler enhancements and everything in order make sure it works well. Meanwhile when AMD releases FX or Zen CPUs, MS is like, "yeah we'll get around to updating the scheduler a little bit in a few months... idk... we're pretty busy making sure Candy Crush works well on UWP."

AMD: Windows 11 Slows Our CPUs Up To 15%, Patch Coming
Renoir

AMD has announced that all of its WIndows 11-compatible processors can suffer from reduced performance in some applications when used with the new operating system, with extreme outliers in eSports gaming titles dropping by up to 10–15%. For applications, AMD says that the performance impact weighs in at 3–5%. A software update and a Windows Update are in the works to address the issues, with both expected to arrive in October 2021 (this month).

The errors impact every Ryzen CPU supported in Windows 11. That means all Zen+, Zen 2 and Zen 3 CPUs that comprise the Ryzen 2000, Ryzen 3000, Ryzen 4000, and Ryzen 5000 processors are impacted. In addition, select AMD EPYC processors for data centers, along with some newer Athlon chips, are also impacted. You can see the full list here, but suffice it to say that every AMD chip on our Best CPUs for gaming list is impacted.
Just in time for the Alder Lake reviews.

Wow, didn’t notice that those timing were with 32GB of RAM 😱. I can’t manage to keep 1T stable anymore. Jelly.
