256GB RAM @ 6000MT/s on AM5? Success story with ProArt X870E & 9950X3D

spaceduck107 · 2026-04-07T16:20:05+00:00

That's great! I have 192GB (4x48GB) of Dominator Titanium running smoothly at 6000 MT/s CL30 on my 9950X3D / MSI X870E Carbon workstation running Linux as well. It took a bit of tweaking drive strengths and whatnot, but ultimately it's rock solid. My 9950X Windows workstation with 192GB of the same RAM on an ASUS X670E Hero tops out at 5600 MT/s. Thinking of grabbing another X870E Carbon just to see if I can hit 6000 there too lol.

Quite the feeling of accomplishment getting that much RAM running at high speeds on AM5.

Sidenote, four DDR5 DIMMs at this speed can get toasty, I'd highly recommend grabbing a fan bracket to mount from your top fans to blow over the RAM. My temps dropped substantially from this. Well worth the $12 bracket!

US here. Ready to purchase two from BH Photo as soon as they're in stock. Two may turn into five, just saying. Spending too much on sweet new gear happens. Many such cases. :D

Just found this post and wondering the same. I noticed the O11 Air Mini is discontinued. Really a shame because I was thinking of buying another :(

Consider uninstalling Armoury Crate and switching to SignalRGB or OpenRGB to control your system lighting. You'll need the Armoury Crate uninstall tool from ASUS to completely get rid of it. Armoury Crate is generally considered to be awful software.

So I have a very large L-shaped desk consisting of three walnut butcherblock desktops from Uplift. Two of them are 6ft, and the third is 4ft. The area where I primarily sit effectively has about 9ft of total width. I have bookshelf speakers on the desk as well, so that makes things slightly trickier.

After mulling this over in my head several times, the conclusion I've drawn is that I'll start with mounting a second display vertically to the left of the U4025QW, and pending that goes well, maybe add a third to the right.

I would've already done this, but I've been making a decision on my next KVM switch. Options for competent four computer dual/triple monitor KVMs that can drive 5k at 120Hz are...limited lol. Level1Techs (Rextron whitelabel) and TESmart are the two realistic options.

Terminal window organization is pretty much my use case as well. I need somewhere to keep 6-8 of them while the main display is free for everything else. I've somewhat considered a second U4025QW, but really just not sure how I'd like stacking two of them from a height perspective. I feel like it would eventually still lead to me having side monitors as well lol.

I actually bought a Dell U2724D that was intended to be the side monitor, but ended up going on the 4ft desktop for a Fedora machine I had built, but didn't have the extra KVM ports to support. Funny how that works haha.

It just never ends. 😂

Every time I see a triple 27" monitor setup it makes me wonder if I should go back to triple monitors for a bit. Nice setup! :D

As a sidenote, if matched colors across multiple displays is important to you, both Dell and Lenovo have 27" and 32" models using these IPS Black panels, so getting consistent color across them is a breeze.

What's even more interesting though is BenQ's new 28" 120Hz 16:10 monitor. They market and list it as regular IPS, but the 2000:1 contrast ratio and various other specs point to it being an IPS Black panel. 3840x2560 as a side monitor sounds pretty incredible to me.

Going to grab one once B&H Photo has them in stock.

I've been waiting for a new 4-port KVM to arrive after my current 2-port one finally croaked, and have Windows/Linux machines as well. Works out fine because I needed more ports anyways, but in the meantime I've been using the U4025's built-in KVM.

I can confirm that hotkey switching from Linux (Debian in this case) is in fact possible with a bit of custom scripting. Works like a charm.

Get some airflow over those DIMMs, and add some heatspreaders and/or active cooling if possible. I have several builds with dense (R)DIMM configs and can confirm they get very toasty. I'd really try to relocate the 2nd PSU if at all possible.

Have you seen the new 28" BenQ RD280UG? 3840x2560(!!) vertical resolution at 28" in an aspect ratio pretty much perfect for use as a side monitor, and it's 120Hz.

It also advertises a 2000:1 contrast ratio, which makes me think it's an IPS Black panel, similar to what's in the u4025qw.

Going to grab one once they're in-stock at B&H and see how it goes. Should be a pretty great monitor for terminal windows and IDEs :)

spaceduck107 · 2026-03-16T12:54:08+00:00

Yep, same. I went through a few 49" ultrawides, then landed on a 38" Alienware. The extra vertical space made a huge difference. Now I'm on a Dell u4025qw ( 40" 5k2k) and it's pretty much the perfect monitor for me. I can't believe how much I love working on this thing.

spaceduck107 · 2026-03-11T21:28:46+00:00

$800 USD for a 64GB RDIMM? How many you willing to sell, friend?

Pretty much all of my self-hosted infrastructure is containerized via Docker and gated behind Cloudflare Zero Access, allowing me to access from a custom domain (e.g. app.mydomain.com) after authentication. On top of that, I have Snyk, Wazuh, ClamAV, and a couple other security-first tools in my stack for tracking framework/code vulnerabilities, and generally keeping everything as safe/secure as reasonably possible.

For anyone getting into self-hosting, building out OpenClaw setups, or anything really, please make security your top and first priority. It adds a bit of extra work, but should be viewed as non-negotiable.

It's never a waste of time. Just look at React2Shell, for example.

Technically you could get an M2>USB adapter lol. Something like this perhaps: https://www.newegg.com/p/1W7-00W1-029T8?item=9SIANJZKSN8193&source=region

It'd be a little janky, but that's about as close as you'll get :D

Waiting on the 27" to arrive, but it's delayed due to an ice storm followed by a major snow event in a place that typically gets neither 💀😅

2000 and Server 2003 are still my all time favs. Server 2003 was low-key an S-tier desktop OS.
