I have the AMD Threadripper PRo 39XX combined with the Asus WRX Pro 80 motherboard. As of right now, I have 128GB of ram via 2 sticks of Kingston Premier Series 64GB 288-Pin DDR4 SDRAM ECC Registered DDR4 3200 (PC4 25600) Server Memory Model KSM32RD4/64HAR.
My question is not about the memory needed to support my system. My question is, should I get another 2 sticks of the same memory to pull out the best for this system? For some reason, I have read about needing at least 4 of the 8 sticks of ram for the Threadripper Pro processor. Now the cost of the ram is not bad, considering its ECC/64GB. I use my computer for CAD, 3D, BIM, etc. This is my work-hours computer, and I used the ECC to stabilize the system.
For the value of the two sticks of ram. I also see from time to time this particular ram on eBay for sale. I missed two sticks for about $400 bucks over the last month.
