Best RAM for a Zen3 SFF build

[Icaz]

I havent built a PC in about a decade or so, and since then times have changed alot on what to value most when deciding on what to buy.

i am trying to build a gaming rig able to handle VR and also run the soon to come out Cyberpunk.

 

My planned build (with most parts ordered and en route or soon to be)

 

AMD Zen3 5600x

Gigabyte Geforce RTX 3070 Eagle OC

Gigabyte B550i Aorus Pro AX

Alpenföhn Black Ridge (with Noctua replacement fan)

Corsair SFX SF600 Platnium PSU

Samsung 970 EVO SSD M.2 1TB

 

in a SFF Dancase A4-SFX V4.1 case (according to the listing it comes with a PCI x16 Gen.4 Riser)

 

My Problem is that due to the limited height on RAM, i am limited to Corsair Vengeance LPX modules (due to their less than 33mm height)

 

so with ryzen performance being dependant on ram speed, would it be better to go for a 3200Mhz CL16 or a 3600Mhz CL18?

(only 2 options i can find in my part of the globe)

 

I dont know if zen3 is about the same in regards to memory as zen2, or if there are other caveats im not yet privvy to

Get whichever is cheaper. The 1:1 ratio will ofset it being cl18 with the 3600mhz ram so really just get whatever of thse 2.

The motherboard should have a memory support list to download, but yours only has it from zen1+zen2 not zen3 (Vermeer), but the zen2 list probably will be similar to the zen3 list. As for the ones you have mentioned CORSAIR appears alot on that list so you should be fine, but I would explicitly check as I haven't.

As for zen2 vs zen3, zen3 likes faster RAM again so the 3600MHz out of your 2 options might be better, but 3200MHz is fine as well. (the performance up lift will only be 1-5% depending)

going by supported RAM, both the 5600x & the mobo is listed as 3200Mhz.

 

from what i recall from the memory testing video from LTT last year with zen2. having better CAS with a lower speed, and boosting the infinity clock instead gave better results. but im not quite sure i understood it correctly tho.

i'd get the 3600c18

nah, i think he said that his mobo and cpu support only 3200? wierd but fine

both mobo & cpu supports 3200Mhz memory speed, im guessing thats a minimum value (the 3600x also supports 3200Mhz memory too) atleast thats how the values are advertised on the local webshops for me anyways

use 3200mhz, ive seen so many ryzen users use 3600 but i think ryzen 5 might be limited
