I have a threadripper system on an Asrock Taichi x399 board that has 8 ram slots.
Originally I had 4 sticks of 8GB ddr-3000 CL15-15-15-35
Just upgraded to 4 sticks of 16GB ddr4-3000 CL16-18-18-38
I was planning on just swapping and selling the old sticks, but figured what the hell and just tried them all. To my surprise The system boots and this is what I get with cpu-z:
I was able to get 2933MHz before with just the old ram by selecting xmp profile in the bios, but now when I try it the system will fail to boot 3 times, do some error correction and then boot normally at 2133MHz.
I tried manually setting the ram timings to 16-18-18-38. Not sure if I was doing it right or not, the same thing would happen with the boot failures 3 times then normal boot and all the settings show the same as above in cpu-z.
So my question is, should I keep all the ram at the lower speeds, or should I get rid of the older ram and stick to my set of 64GB so that I can get better speed and stability?
