Crucial Ships 128 GB DDR4-2666 Modules for Servers at $3999 per Unit
Article said:
Crucial has started shipments of its fastest and highest density server-class memory modules to date. Crucial’s 128 GB DDR4-2666 LRDIMMs are compatible with the latest memory-dense servers. These modules should be usable in both AMD EPYC systems and Intel Xeon systems, however Crucial states that they are optimized for Intel’s Xeon Scalable CPUs (Skylake-SP) launched earlier this year, and are aimed at mission-critical RAM-dependent applications. Due to the complexity of such LRDIMMs, and because of their positioning as super dense memory, the price is very high.

Crucial’s 128 GB LRDIMMs are rated to operate at a 2666 MT/s interface speed with CL22 timings at 1.2 V. The module is based on Micron’s 8 Gb DRAM ICs, are made using 20 nm process technology, and are assembled into 4Hi stacks using TSVs.

I am (a bit) surprised how expensive those are.

Looking at Newegg, 64GB DDR4 ECC LRDIMMs are about 1/4 the price:

Larger modules have always be disproportionally more expensive and these ones are harder to manufacturer giving even more reason for them to be more expensive.

That and the fact these aren't being bought by people who care about the cost. They just need as much density as possible which will pay for the memory in the long run.

yea, they managed to fit it on a standard height dimm based on one picture, amd with the price of ddr4 right, not surprised at the price.

So, if you want to max out Epyc, that would cost a cool $64K.

That's a deal, $/GB. Like a year ago, it cost us $25k to buy an R630 with 512GB of RAM. With 32GB it was a $5k box.
