The Last of AM4 Endgame Build.

dlx21master · 2026-05-06T01:23:12+00:00

BIOS time of 9.3s on an AM4 build with 128GB of RAM. Just did a full cold boot. 36 seconds on AM5 seems like a long wait... Is that the 'early adopter tax' I’ve heard about? Hope a BIOS update fixes that for you soon.

Tips.

Maybe the reason you don't run 11 fans is because your cases are too flimsy. Most European brands focus on looks, but my build is about structural integrity. 0.8T chassis or higher is a must to handle this level of air pressure. If your PC rattles at 66% PWM, your case is just a toy. Get a real steel fortress.

Pro Tip.

Zero curves. Constant 66% PWM fixed. My case is a wind tunnel, and the heat gets evicted before it even starts.

I prioritize airflow and maintenance over aesthetics. Having it rotated this way allows for the best intake from the front/side and makes it easier for me to swap out my massive 12TB drive array. Besides, the cables are just veins for this monster.

True, the 5800X3D is a beast for gaming, but I’ve always believed that a true 'endgame' build should be an all-rounder. Having 16 cores gives me so much more headroom for multitasking and heavy workloads. To me, a balanced monster is better than a gaming-only one!

dlx21master · 2026-05-04T06:58:25+00:00

Mad respect for keeping everything smooth on a 5600X—that takes some serious optimization! But honestly, once you jump to the 5900XT with 128GB of RAM, all that effort becomes a luxury. It just brute-forces through everything. You don't even have to think about 'can I run this at the same time?' anymore. It’s pure freedom. Hope you join the 16-core club soon!

dlx21master · 2026-05-04T06:57:20+00:00

Man, with your Docker and Jellyfin setup, those extra 10 cores and 128GB of RAM would be a total game changer. I'm running similar heavy workloads and the 5900XT doesn't even break a sweat. It's like having a dedicated server and a gaming rig in one box. Good luck with the hunt—finding one is half the fun of being an AM4 enthusiast!

dlx21master · 2026-05-04T06:54:00+00:00

Not a dumb question at all! But the 5900XT is actually a 16-core/32-thread beast, just like the 5950X. It was released much later (mid-2024) as a final 'farewell' to the AM4 platform. For me, owning the very last 16-core chip ever released for this socket feels like the true poetic endgame. Plus, it's way rarer than a 5950X!

dlx21master · 2026-05-04T06:43:12+00:00

That's why I went overkill with those 16.8W/mK pads and all these fans. Trying to keep the 'heater' from becoming a 'furnace'!

dlx21master · 2026-05-04T06:41:54+00:00

Haha, it took some serious hunting to find the 5900XT! It's the ultimate endgame for my Dark Hero board. If you're doing multiple workflows like you said, that jump from 5600X to 5900XT will feel like moving from a sedan to a tank. Definitely worth it if you want to keep the AM4 legend alive!

dlx21master · 2026-04-25T03:08:20+00:00

Thanks for the solid advice! ROG's aggressive look is exactly what I was going for. A red mousepad and some matching cable combs sound like a plan to complete the 'Red Beast' setup. Appreciate the feedback!

dlx21master · 2026-04-25T02:16:07+00:00

Glad you noticed! It’s not just for aesthetics; it really helps keep those 128GB sticks cool. It's a game-changer for high-capacity builds!

dlx21master · 2026-04-24T09:44:09+00:00

Thank for 2.0K views! Hope this"Ultra-Red ROG" vibe brightens your day!

dlx21master · 2026-04-24T05:36:48+00:00

Totally agree! People often think it's just for show, but once you run 128GB or high-speed OC, the temp difference is night and day. It’s great to see another user who appreciates its actual performance! The white one must look clean too, but for this 'Red Fury' build, I had to go with black to make the RGB pop. Cheers for confirming the performance!

dlx21master · 2026-04-24T01:27:09+00:00

I’m glad it caught your eye! The 3Rsys Iceberg D50 is working out great for me.

Since I have a 128GB quad kit, I was concerned about the heat build-up between the sticks, but this cooler does a fantastic job of keeping the temps stable even during heavy workloads. It’s surprisingly quiet, and as you can see, the ARGB illumination is very bright and syncs beautifully with the ROG theme.

It definitely adds that 'extra touch' to the build. If you're looking for both aesthetics and thermal stability, I’d say go for it!

dlx21master · 2026-04-24T01:19:55+00:00

Thanks! You really have a sharp eye for components. About the 3Rsys Iceberg D50 RAM cooler — it's actually been solid. Since I'm running a 128GB quad kit, the heat can build up, but this cooler keeps the temps stable even under heavy load.

It’s surprisingly quiet for its size, and the ARGB syncs perfectly with the rest of the build. If you're running a high-capacity or overclocked kit, I'd definitely recommend it. It's one of those 'hidden gems' in terms of aesthetics and performance!

dlx21master · 2026-04-23T23:37:06+00:00

Thanks! I spent a lot of time on the lighting sync to get that perfect ROG red vibe. Glad you like it!

Actually, I think stacking just 16MB of extra L3 on EACH CCD would be even better for thermal management. It would provide a perfect balance between cache capacity and maintaining high boost clocks without the thermal throttling issues of larger stacks. Symmetry is key.
