Question expected performance when adding more memory

[daggs1]

Greetings.

I have ryzen 2700x cpu paired with f4-3200c14d-16gfx clocked at 3200mhz (xmp enabled in the bios, version is F4 currently) on a ga aorus 450b m mb.

I'm thinking of adding additional f4-3200c14d-16gfx kit so I can bring it up to 32Gb, can I expect 32Gb ram running at 3200mhz?

it is more likely that with four slots filled your memory speeds will drop to 2666mhz instead as that puts more stress on the memory controller.

See my thread in Motherboards. I installed a Gigabyte Aorus B450 WIFI PRO ATX mobo, with 4x8GB Team Vulcan DDR4-3000 RAM, and I have ALL of it, running at XMP, 3000 speed, 1.35V. So far, so good. Although one afternoon I was having repeated appcrashes with Firefox Nightly, but that could have been just a bad updte. I got some updates, rebooted, and everything has been fine since. No BSODs since assembling this rig with the new mobo.

Edit: My RAM is apparently Hynix, and not even B-die, which is IMHO even more impressive. A big thank-you to the physical layout team and BIOS engineers at AMD and Gigabyte, and Hynix, for making this happen.

Does your memory use Samsung B(or is it D?) dies? It is my understanding that is pretty required to get higher then DDR4-2666 speeds with four memory slots filled.

the f4-3200c14d-16gfx is Samsung B-Die, I'd assume that if VirtualLarry's setup works with hynix ones, it should work with mine

That would depend your boards BIOS/UEFI and board design.

so after a few support disscussion with the mb's vendor (GigaByte) it seems like they don't know what they are doing, (the don't like that kit as supported but list a similar 32 gb kit with the same spec per dimm as supported when they never tested it nor seem to notice that the ram vendor states that this memory is not compatible with am4 boards.) so has anyone tried to run two kits of f4-3200c14d-16gfx in full speed on this mb? (ga aorus 450b m mb).
