Hi folks,

I've ran across AMD EPYC 4484PX (12 core) and AMD EPYC 4584PX (16 core),
they're slightly higher priced than 7900X3D and 7950X3D Ryzens,
it seems they offer more PCIe lanes (28) and better memory controllers also with ECC support, while being designed for "same" AM5 socket,

anyone knows which (if any) consumer motherboards are actually compatible with them?

 

Mr. GPT says:
There are several ASUS motherboards that are compatible with AMD EPYC processors and support ECC (Error-Correcting Code) memory. Here are a few options:

1. ASUS ROG Zenith II Extreme Alpha - This motherboard is designed for high-performance computing and supports AMD EPYC processors. It also has support for ECC memory.
   
   
2. ASUS WS C621E Sage - This is a workstation motherboard that supports dual AMD EPYC processors and is designed for server and workstation applications. It supports ECC memory.
   
   
3. ASUS ROG Strix TRX40-E Gaming - While primarily aimed at gamers, this motherboard also supports AMD EPYC processors and ECC memory.
   
   
4. ASUS Pro WS WRX80E-SAGE SE - This motherboard is designed for professional workstations and supports AMD EPYC processors with ECC memory support.

When selecting a motherboard, make sure to check the specific model's specifications to confirm compatibility with the desired EPYC processor and ECC memory, as well as other features you may need for your build.

---------------------------
And I can tell you it is not worth it if you're looking for better RT/audio performance. EPYC processors and motherboards can actually perform worse under certain conditions/with RT audio and with games, too. They are optimised for server workloads. A better option would be to buy a motherboard that supports ECC and a "Pro" version of AMD Ryzen processor.
---------------------------

Mr. GPT again:
There are some ASUS AM5 motherboards that support ECC memory, particularly those aimed at workstation or professional use. Here are a few options:

1. ASUS Prime B650M-C - This micro-ATX motherboard supports AMD Ryzen processors and has ECC memory support, making it suitable for more stable and reliable builds.
   
   
2. ASUS Prime B650-PLUS - This ATX motherboard also supports ECC memory and is designed for business and professional applications.
   
   
3. ASUS ROG Strix B650-E Gaming WiFi - While primarily a gaming motherboard, it does have support for ECC memory when paired with compatible Ryzen processors.

When considering a motherboard for ECC memory, it's essential to check the specific CPU compatibility, as not all Ryzen processors support ECC, even if the motherboard does. Typically, ECC support is more common with Ryzen Pro processors. Always refer to the motherboard's specifications and the CPU's documentation for confirmation.

----------------------------
I would go with ASUS Prime ("Prime" is like "Pro") B650-PLUS and AMD Ryzen 7 Pro 8700G (cheaper and w/VGA) or 7745 because they have higher base clocks at 3.80GHz ( here's the list of Pro AM5 CPUs) rather than EPYC. Find some benchmarks and see for yourself which is better for you. It's interesting to note that "Pro" processors only differ in ECC support and a bit higher price.

Look here, good info: Asus Prime B650-PLUS CPU/memory support. ECC support depends on the CPU and RAM used. I like ECC memory myself. Good stuff. No occasional random reboots once every few months due to solar activity or PSU/power instability, or a Gypsy curse.

Cheers!

ah, generic chatbot nonsense, C621E is Intel chipset for 3647 Intel socket

so I guess ASUS ProArt remains the GOAT choice with practically no worthy alternatives

 

Yeah, true, I realised Al's answer wasn't really spot on. I had to edit some things... but I hadn't realised that C621E is an Intel chipset. Dmn! It did caught my eye, though. Like wtf's that?

What kinda monster are you trying to make tzzsmk? Do you need corpses?

I hope you don't mind my sense of humour, mate. And I always take assembling a monster rig really seriously. It's always the coolest project on the block and wider, as you can learn a ton. I have peaces of Ryzen 7 9700x based rig in the left corner from me waiting to be glued, spanked and abused.
