Question Adata Dimm's & Micron ICs with AM5 overclocking?

[Hotrod2go]

As per the title. I've heard that Micron IC's are not very good at overclocking on current AM5 platform. So just wondering if this is really true?

My kit is a cheap 4800 CL40 kit I acquired a year ago in a clearance sale. Obviously designed for Intel's alder lake platform as the date of manufacture is late 21'.

So far on my AM5 platform, I could do 5200 CL40 @ 1.15v for VDDIO-MEM with my 3 pronged attack to ensure RAM OC stability.
Atm, I'm trying for 5400 CL40, but left the timings on auto in bios with 1.20v. This passed ok with memtest 86 & also MS memory diagnostic in default run, but Memtest Pro would throw up errors with less than 100& coverage.

Anyone else out there in AM5 overclocking world had experience with these types of DIMMs before??

Ok, so after several days of testing with various configurations, the best I can do for daily usage stability is 5200 CL38 in over 400% coverage with Memtest Pro. Funny thing is the last thread or number 16 to us mortals is lacking a bit in speed coverage for that particular thread. Not sure if this is a bug in the app or something else going on. But afaik the author of this app has not updated it since DDR5 platforms were released. I never do any of this RAM testing before testing in pre OS environment with something like memtest 86 (v10.4 currently), so if all passes there then its onto the next round of testing & that is to run Microsoft's memory diagnostic app for at least the default run.

Upon further refining of the bios settings, able to run this budget 1st gen DDR5 kit to 5400MHz CL38, MTP stable for 400+% coverage. All with PBO tweaking & 2166 FCLK.

Interesting observation about the peculiarities of AM5 & 7000 series IMC effectiveness in relation to FCLK & tREFI settings. I gain another 5GB\s in overall score with MaxxMem2 memory benchmark app & a nice reduction in latency just by changing those two settings & nothing else whatsoever apart from those 2 settings as shown in the images demonstrated below;




Wonder what more discoveries can be found in this new technology!
