RAM for AMD Ryzen 7 5800X

1 : Anonymous2021/08/18 17:56 ID: p6wfx2

Hey guys, I want to add 32GB of RAM, which one of the following is better?

G.SKILL Ripjaws V Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300) Intel Z170 Platform Desktop Memory Model F4-2666C15D-32GVR

Corsair Vengeance RGB Pro 32GB (2x16GB) DDR4 3200 (PC4-25600) C16 Desktop Memory – Black

Open to suggestions. Thanks for taking hte time!

The Corsair ram is faster. Ryzen loves 3200 to 3600MHz ram. The best you can get is 3600 C14 but it is quite expensive. Your good options are 3200 C14, C16 or 3600 C16. It all depends on your regional prices and what you can find.

Crucial Ballistix 3600CL16 is the go-to Ryzen RAM that is also reasonably priced. If you want 2x16Gb, I would look at these:

These also OC higher than 3600cl16 if you are willing to tinker.

The faster the better, upto 4000mhz at max. 3600 mhz cl 16-18 are the best for the price typically.

From the 2 you listed, def the 3200mhz.

I wouldn't go under 3200mhz, now then I only paired some hyper x fury kit with my 5800x, nothing fancy but it gets the job done

3200 or faster is recommended for Ryzen 5000. I went 3600 CL16 and have the IF set to 1:1. Note, my 5800X would not run the IF at anything higher than 1800. So 4000mhz ram would be pointless in my system.

... 4000mhz ram would be pointles...

And this highlights why it is well worth going for a quality kit of 3200-3400MT dram. Set XMP for easy performance and manually tune from there. I have two 2x16 3200 cl14 that does 4000MT/2000IF c16 no sweat on my 5950x. My 5950x is a decent sample in that I get no WHEA errors @ 4000MT/2000MHz IF but for most people trying to set xmp on a kit above 3600MT it's going to be a bad time.

crucial ballistix 3600mhz cl16 imo

I have a 5800X and I tested it with DDR4-3200 C14 and DDR4-3600 C14. Even in the beste case the difference was just 5%. My advise is to get a DDR4-3200 kit with as low timings as possible AND pupulate all memory slots. That way you gain a little performance from memory interleaving. On the single CCD CPUs, DRAM speed and therefor Infinity Fabric speed isn‘t as important as on the 5900X and 5950X.

Get 2 kits Gskil 3600C16 Ripjaws V they are going for around $125
They should do 4000C16 easily with tight tFAW and tFRC

I have my kit since 2017 and works 4000C16 at Intel CPUs (6700K, 8600K), 3600C16 when got the 1800X (when many couldn't make 3200 to work) and 3800C14 with the 3900X.

I have these exact sticks and they run rock stable on my 5800x running the XMP profiles.

Once you go over 3600, the 1:1 IF speeds (1900 and up) get questionable in my experience. Some can do it...it's just the silicon lottery at those speeds.

Here's the RAM I'm using - super nice, works perfectly with 5800x, x570-e ASUS Mobo:

G.SKILL Trident Z Neo (For AMD Ryzen) Series 32GB (2 x 16GB) 288-Pin RGB DDR4 SDRAM DDR4 3600 (PC4 28800) Desktop Memory Model F4-3600C16D-32GTZN

As others have said 3200mhz or faster with a low CL, 16 or less, ideally 14 or less.

I'm running a 5800X with G.Skill Ripjaw V 3600 CL16 @ 3800 CL16. At the time it was a good balance of price to performance. Runs great.

Just see the Memory QVL list when you have bought the motherboard
