precision 7875 approved ram list
Hello, I recently purchased a 7875 and I'm trying to find memory modules that will work with this system at 5200MT/s. I purchased an 8x16gb kit of corsair ws (not my first choice, but the price was good...) workstation ram rated for 5600MT/s which per Dells and AMDs documentation should work at 5200MT/s on Threadripper 7000 platform, but it didn't. Memory was only able to run at 4800MT/s and also caused boot failures when more than 6 sticks were installed.
Long story short - can we get a list of 16gb and 32gb modules that Dell tested and certified to run at 5200MT/s for this system? Or at least part numbers for the dimm modules Dell sells as compatible upgrades? Either manufacturer or Dell part numbers would be fine.
Thanks!
JK
