Bad x570 motherboard? OC RAM issue

KingJimmyJoe · October 23, 2020

Hey guys I bought msi x570 tomahawk a few days ago to replace my b450 tomahawk max. Previously with b450, I was able to OC my 3200mhz cl16 to 3800mhz cl16 with tight timings (took me almost a week to fine tune). But now with x570 tomahawk, I can't oc past 3600mhz cl18. I have adata xpg d60 3200mhz cl16 CJR. I re-tried with b450 again and it works perfectly at 3800mhz. So after all the swapping and experimenting, I concluded that either this x570 tomahawk doesn't play well with my ram or this has bad ram/memory control? Is it something that I can ask to exchange/return/RMA or something? Other than that all other aspects work perfectly. FYI I tried 3866mhz and did not post even with all loose timings. And the ram is listed in msi compatible list.

One motherboard' setting won't necessarily transfer 100% to another motherboard.

The self-relearning process, and motherboard PCB layout / topology are different.

Do you have the latest BIOS on your new X570 board?

Memory Controller is within the CPU, and is not on the motherboard.

Yes I have tried both latest and beta versions of Bios but none can do a better job than the other. Even at 3600mhz, I cannot do tighter timings than 16-18-18-36. I understand settings on MB won't be carried forward to the next but I was just expecting much better result on this X570 Tomahawk since my B450 Tomahawk max did a great job at OC RAM and undervolt CPU. I have to say I'm a bit disappointed. So meaning to say that I can't really return this board for this reason right?

I would really like if some oc professional could share a bit of knowledge on this topic. How could 5th best amd mobo ever made perform this bad? or is it simply faulty?

My bad for forgetting to reply on this. I found the problem and wasn't anything to do with whatever we thought I was facing. I forgot to mention that I'm using Cooler Master GPU Vertical Bracket V1 PCIE3 and therefore classic issue of PCIE 3 and PCIE 4 not playing well which somehow random slow boot/no post/BSOD and etc. I got everything up and running after changing PCIE 4.0 to PCIE 3.0 in BIOS and this is what I got. ADATA D60 3200mhz 16CL OC to 3800mhz 16CL. All test passed with no errors, tested with memtest86 via USB Bios, TM5 extreme@anta777 config, Prime95 and needless to say, Aida64.
