It may be of no concern to many, but 3D artists constantly express problems with filling DIMM slots when using Threadrippers. Supposedly, 128 GB RAM is only reliable on a couple of motherboards. I just constantly read these stories on forums. (And to be sure, these aren’t situations where users were mixing RAM sets)
- sounds 8y agoI've seen that as well. I believe it boils down to a few AMD motherboard integrators that have rushed out products that are marginal - they work ok for simple use cases, but maxing them out reveals some edge cases they didn't work out. The solution, of course, is to name them. Can you share which motherboards you've seen people complaining about?
- dragontamer 8y agoAMD's memory controller has worse compatibility compared to Intel's. AMD's 1st Gen Ryzen was known to have issues with Hynix dies. Remember: DDR4 goes straight to the CPU these days. I'm fairly certain that motherboard makers can make a simple wire connection between the DDR4 pins and the CPU itself without much issue. https://community.amd.com/thread/217871 https://community.amd.com/thread/217871 The AMD Community knows to avoid Hynix and to buy Samsung. Hynix did improve with some BIOS updates (in particular: increasing V_soc voltage to 1.1 and other tricks). Update your BIOS if you have any issues. Zen+ dies have better DDR4 compatibility.
- ksec 8y agoHasn't the latest BIOS fix most of the issues? AMD's memory controller is actually from Rambus. The good thing is as more EPYC moves inside DC, there will be lots more memory testing done for AMD.
