Question whats the maximum ram speed i can achieve with the A520M H (rev1x) and the b450M vdh pro max (both micro atx boards)

[lkaypcs]

i figured a ryzen 5 3600 would be a good cpu to use but when researching motherboards i was curious about the maximum ram speeds i could achieve with xmp (docp for amd) because apparently the B450M vdh pro max can overclock to 3466mhz from 3200mhz but i was aiming for 3600+mhz. However on the a520m H i was wondering with docp how much i could overclock the ram because from research it says that its limited to 3200mhz unlike the b450m. Could anyone help

Memory overclocking is limited much more by the quality of the CPU's memory management unit.

But...A520 has very limited overclocking allowed. Can you do more than just enable DOCP? meaning...can you manually set memory clocks to anything you want? and can you manually edit the advanced timings? If not, you can on the B450 so someone with the know how could probably tweak in a better overclock.

But even with DOCP...if you have a kit rated at XMP 3600 (sweet spot for 3000 and 5000 CPU's) enabling DOCP (or XMP if not Asus) should work the same whether B450 or A520. But if you can't manually tweak timings (or voltage, or frequency) on A520 then you can't fiddle with those to make it start up or be stable should you have a weaker CPU MMU.

3600mhz would be a good target to shoot for as stated above. The 3xxx series CPU's & up can usually hit that speed without issue regardless of what the motherboard says.

Case in point, my old B350 motherboard was struggling with 3200mhz with a 1600x CPU but handles 4 sticks of 3600mhz with a 5700x no problem.
