AMD 9800X3D - Any Pitfalls?

Oh, I was tempted! :slight_smile: But like I said, if something doesn’t work, I won’t be able to let myself rest until I figure it out. Even if so much as a single fan doesn’t spin or a single port on the front panel doesn’t work, I’ll tear my hair out getting it fixed.

Better to start that process this afternoon after work when I have a big block of unscheduled time for it.

There’s also the tiredness factor. Stay up and it’ll take you three hours to fix something that you’ll sort in ten minutes with a fresh head first thing in the morning.

You have the same case as I do: The Corsair 4000!

This is the Frame 4000D version - the modularity and configurability is pretty wild. I’m strongly tempted to move my AIO radiator to the side and install three more top-mount exhausts. Not because I specifically need to, just because I can, lol.

I recommend maintaining positive pressure inside a case.

Here is mine:

I put my CPU cooler fans at the top and added 1 to the rear.

My Corsair Vengeance PC came with this case. Excellent case for cooling with lots of airflow

Cue the Young Frankenstein/Gene Wilder meme: It’s alive!




Whew. :slight_smile:

Congrats. Nice job and nice PC. You did good!!

Good Job!

Having learned the MSI BIOS quirks - the versions ending in zero are stable, the others are beta tests. So it looks like the latest stable one for your board is 7E51v1A60 from June 24, which I would recommend because it has the new AGESA 1.2.0.3e fixing a security hole and improving DRAM compatibility, etc.

So once Windows is installed, be sure to install the Chipset driver, then other motherboard drivers (LAN, Wifi, Bluetooth), then Windows update until it’s happy.

I’d suggest then it’s worth downloading a few free pieces of software to capture a baseline benchmark of speeds and temperatures at stock BIOS and stock Windows settings before customizing:

  • Cinebench 2024 (CPU benchmark)
  • Geekbench 6 (CPU and GPU benchmark)
  • ZenTimings (to show memory timings)
  • HWInfo

If you use HWInfo, turn on Snapshot CPU Polling for AMD processors, which lessens the impact of monitoring on the CPU itself.

If you open the HWInfo Sensors window before a test, and click the little clock at the bottom to reset it’s stats, and run one of the benchmarks and screenshot it during and after results, you’ll accumulate info on temps, voltages and speeds so you can then use to compare later when you turn on EXPO and/or PBO.

There is only 1 other quirk worth mentioning: If you have the standard Windows Hello PIN code set up to log in, updating or replacing BIOS seems to wipe out the PIN so the next boot of Windows will complain, but it then offers to just set up the PIN again, which is easy enough.

Finally if you decide you want the latest AMD chipset driver (currently from Aug 4th), you can get it here with the “Auto Detect and Install”. I selected the Custom Install and then just the Chipset driver updated.

Note, I just posted a PSA that the latest Windows Update KB5063878 might corrupt data, especially on specific SSD models, so I’d recommend rolling back that update if you’ve already installed it…

Yep, just ran into that one myself, as I did update the BIOS earlier tonight. Interestingly enough, my prior rig is an MSI-based Intel board (Z590 Pro WiFi) and although I’ve updated the BIOS several times over the last few years and Windows never complained.

Anyway, appreciate the tips - this thing flies. I went from 60-70 fps in the Miltech MH60 at mostly-high end settings, to 100-120 fps with everything set on Ultra across the board.

Of course this is anecdotal and only a single aircraft at a single payware airport (the Coast Guard station at VerticalSim’s KPIE) but it’s a nice first impression.

I’ve got a lot of stuff to download, install and move over, and I’m sure a bunch of tweaking. But it’s defintely mine. :slight_smile:

That’s awesome. I love it when a plan comes together.

I highly recommend enabling EXPO, and PBO with an All Core Negative 10 offset (to start with). Combined those 2 things will reduce temps and improve performance by about 5 to 7%

I used the MSI Mystic Light software to make the RGB light change based on CPU temps - so that the colour is informational instead of just illuminating.

If you want any guidance tuning more specifically, I’ve just been through a learning curve of under-volting on similar hardware (which was fascinating to the OCD part of my brain) so feel free to ask and I’ll help if I can.

Placing the AIO radiator at the front is an interesting choice - instead of drawing in cool air from outside the case, the AIO radiator’s fans pull hot air from the radiator directly into PC case. Did someone suggest it to you? Just curious. Also, congrats on starting your AMD journey – after 30 years with Intel, I switched to AMD myself and haven’t regretted it.

I’ve never understood that config. I would put the three Corsair fans on the front as intakes, and put the radiator on top as exhaust.

Thank you for that important info!

JayzTwoCents posted this video and mentions KB5062660 as well.
The issue is with those updates interacting with drives that use a Phizon controller, potentially corrupting data after large file writes (like installing a game.)
He also lists all the drives that are known to have had data corruption.

ETA: I checked my laptop and tried to uninstall KB5063878. It failed with Error 0x800F0825, which AI tells me is:

“Error 0x800f0825 typically indicates a problem during Windows update or installation, often due to pending updates, corrupted system files, or a corrupted component store.”

Great…

There is a command line that will work, I posted here:

That’s … not how the case is configured. The 360mm radiator is on top configured as an exhaust. There are 3 x 120mm intake fans at the front of the case and one 120mm exhaust fan at the rear.

You’re right – I must have still been half asleep when I wrote my earlier comment :rofl: I watched the video again and luckily your setup looks perfectly fine :+1:

The fact that the coolant tubes are routed to the front may have mislead you. I wanted initially to rotate the radiator 180 degrees, but having the tubes at the rear interfered with placement of an exhaust fan. No way around that in a mid-tower case absent going to a front- or side-mounted radiator (both of which could be accommodated in this case if desired).
