In my current system (X370 Taichi and Ryzen 1700), I have problem running my RAM sticks (G. Skill Trident Z 3200MHz CL14) on their advertised speed and timings (3200MHz and CL14). I can't get them table. I am wondering whether I can my RAM modules with 3200MHz and CL14 if I replace my current CPU Ryzen 1700 with 2700X. Memory controllers in new CPUs are better and must be stable with all the RAM modules. But I am not sure because the instability problem that I am experienced can be related to my mobo as well. Note: I am running the newest BIOS available and still the RAMs modules are not stable.
They present no problem when I run them with default BIOS settings. Instability arise as soon as they are overclocked.
this is something I'm curious about too. I have some of the crappiest Hynix memory and my 1600X won't run then at 3200 even with sloppy timings. I was thinking of changing out the proc because of this.
I do run 2700X + 4x 8GB g.skill 3600MHz CL 16 sticks. I do run them on 3066 CL14. Because while I managed to get 3200 even 3333MHz error free in all memtests. I got few times a day SSD corruption. With 2x 8GB, it would likely be fine. Secondly, I get ~1900 in cinebench R15 with CPU on 4.225GHz regardless of running 3333MHz CL16 or 3066MHz CL14/16 as I tested both. I can't enable boosting, so I run all cores on 4.225GHz. I have boosting disabled because memories on 3200MHz did not like 1.45V on CPU and more. I'll probably retest on weekend as CPU was boosting to 4.35GHz out of the box and delivered around 1825 in cinebench R15 with default 1866MHz CL13 memories. So, it's not like impact of memory clock is as big as it was with Zen.
