Shortages or not, there's little demand for cool new motherboards and CPUs from the enthusiast corner of the market because hardware platforms themselves are stagnating performance-wise.

13-14gen Intel Cores are still more than enough for your average home gamer, Zen 5 shows only marginal improvement over Zen 4 except for a very narrow range of workloads, getting wider than 128bit memory bus is prohibitively expensive while relatively cheap consumer boxes like Mac Mini run circles around dual-channel DDR5 setups, so on, so forth.

Sure, presenting this as a consequence of AI boom is convenient for a news outlet, but even before the craze both Intel and AMD were dragging their feet.

I'm not buying it. Both the premise and the new motherboard, that is.

I wanted to build a Threadripper 9965WX and the math worked out until DDR5 prices come in to play. Instead I got a used Lenovo P620 5975WX and still had to buy DDR4 from Shenzhen to get anything remotely affordable. The IPC of the Zen5 is a meaningful uplift especially for single thread but it is out of reach.

Where/how did you buy your DDR4 from SZ? Interested in doing the same, but want reputable source/supplier.

The seller was Focus Memory on Newegg, DIMMs are Rimlance. It arrived quickly via DHL. I'd be a little sketched out to do this if it wasn't registered ECC. The dies appear to be Micron, register IDT, but there is some possibility of soft fraud where they die printed over something. The registers look a little scratched so I wonder if they found some way of recycling DIMMs or even dies. The SPD is their own.
