There are only three (tiny) 12 V power pins on a DDR5 module, neither that nor the form factor allows for dissipating anywhere close to 150 W. The teased 512 GB Samsung module doesn't even have a heatspreader.
- __alexs 4y agoVIN_BULK is 5V with a max current of 2A but every data pin provides current that is used on the DIMM in some respect.
- formerly_proven 4y agoI thought they moved to 12 V, thanks for the correction!
- __alexs 4y agoI'm just going by the Micron UDIMM data sheets. https://media-www.micron.com/-/media/client/global/documents/products/data-sheet/modules/unbuffered_dimm/ddr5/ddr5_udimm_core.pdf?rev=fdbd9476506c4e019360a5e402827caa https://media-www.micron.com/-/media/client/global/documents... Looking a bit closer I think you are right that it's 12V but only for Registered DIMMs.
