Could be wrong, but I don't think you can. The bandwidth limit, AFAIK, is a problem with the DDR5 spec. These soldered solutions can go faster specifically because they aren't DDR5.
- sunshowers 2y agoHmm, I think a Threadripper 7965WX can get you there. Probably around 4-5k all in so I guess similar pricing to a Mac Studio.

- sliken 2y agoPlease don't misused channels. In DDR4 1 channel was 64 bits. In DDR5 1 channel is 32 bits. So a 128 bit wide DDR4 system had 2 channels, but a 128 bit wide DDR5 system has 4 channels. The latest AMD server is 12 DIMMS wide, but has 24 channels of DDR5.
