Which is the best ram kit to use with the Asus Prime B550M-A motherboard with Ryzen 7 5700G, is it Crucial 16GB DDR4-3200 with CAS Latency 22 or Crucial 16Gb DDR4-2400 with CAS Latency 17, though to using 4 of 16 Gigs to make it 128 Gigs.

Hey,, there, Igor! [My initial backup has started per the other threads. I'll have anxiety until I see it's completed at least 50%.]

He's got a Ryzen system. I don't understand why one would purchase RAM with such a high CAS latency of 22. Or why you'd want RAM with 2400 DDR.

I bought my G.SKILL RAM five years ago -- DDR4-3200 14-14-14. Another system I'm building will use G.SKILL Rip-Jaws with CAS 16.

Is this about price?! The RipJaws -- not necessarily Ryzen compatible but I wouldn't know -- were about $120 for a 2x16GB pair. HOW CHEAPLY can you get a RAM kit of ANY performance spec?

It just seems to me that for building a system, a kit for $120 is a decent price. I always try to buy performance RAM, but I'm happy with DDR4-3200. And these are older systems -- no good for Win 11 unless I want to try the hacks being discussed lately. My TridentZ DDR4-3200 14-14-14 GTZR's were about $250 for a 2x16GB kit. I wanted to configure 64GB for this second system now in the works, so I bought the cheaper Rip-Jaws with CAS 16.

14-14-14 is hard to find for a 128 gig kit. Not even sure if it exists. That's why pointed the OP to a CL16 DDR4-3200 128GB kit. He's welcome to pay a little more for slightly slower CL18 DDR4-3600 on that page. G.Skill would cost him more methinks. Up to him how much he wants to invest.

OP's last sentence said something about using 4 of 16gig, but that's 64GB, not 128.

"Why do you need 128GB memory" is another question that I guess I should have asked. I doubt that a 5600G is going to be able to run 4x32 at top speeds, so 3200CL16 might be perfectly adequate in that case.

(I don't want to admit what I paid for my 2x16 of 3200CL14 TridentZ in mid 2018. Way more than what the Duck paid.)

What is this system used for? How much RAM do you need?
