[SOLVED] XMP w/ 3600 C16 vs OC w/ 3200 C16

[Hypercore_Gaming]

I’m building a computer very soon, and I have a decision to make about memory. I would OC if I haven’t heard that it is time consuming and not easy. So should I spend the extra few bucks or should I try OCing? I’m getting the R5 3600 no OC, and MSI Tomahawk B450 Max

it is time consuming and not easy.

and sometime it won't oc.

You're getting the 3600 with the tomahawk max. Buy 3600MHz CAS16 2x8 or 2x16GB and just by using the XMP profile it should be good.

Buy the 3600mhz memory with 16 cas simple BIOS setting enable XMP and run 3600. The native memory speed for the 3XXX processors is 3200 but if it's not stable at 3600 you can always just set it to 3200 or go through the process of adjusting timings or voltage to get it stable at 3600.

IN ALL HONESTY THEIR NOT A LOT OF PERFORMANCE GAIN FROM 3600MHZ 16 CAS AND 3200.

It all depends on what you do and what you can do. 16-16-16-39 @ 3600 is a damn site better than 16-18-18-48 @ 3200. It's not just Cas or speed to consider. If you dropped the cash for some C14 3200, then you'd be close to C16 3600.

Ryzen runs infinity fabric. That's the communication between its cores. It's based on the rams Data rate. So the faster the ram, the faster the cpu can think and do stuff. But there's a caveat. A cap. For 2nd Gen Ryzen, it was 3466MHz, so 3200 became the sweet spot, fastest ram. For 3rd gen, that cap was bumped to 3733MHz, so 3600 is the sweet spot. That's with the IF at a 1:1 ratio. Above those speeds, IF automatically switches to a 1:2 ratio, cutting the Data rate in half. If you know where to look, tinkering can change that on some mobo's, but for most, 3600 on a 3rd gen is as good as it gets.

You assume the 3200 will OC to 3600 levels, it stands a good chance of not being binned for such and maybe only being stable at looser timings at 3466MHz. Better off getting the better binned 3600 ram

I don't want to hijack this thread but I own the G.Skill 3600 C16 ram mentioned above. The ram chips are Hynix djr and I used dram calculator to manually clock it to 3400 c14. with my Ryzen 2600x. It won't run stable at 3466 or higher even using the safe settings. From reading what Karadjgne said, would I be better off clocking it at 3200 C14 instead of 3400 C14?

If you can get the ram to 3400 C16 with the same timings as 3200 C16, the 3400 will be better, but being that close you may or may not see any real gains. But if you have to loosen the other timings to do so then the 3200 will be better. It's a dance.

But understandable why 3466+ is unstable. A lot can depend on the motherboard and cpu too, not just the ram. Some pc's ran perfectly with 2933MHz, but 3000MHz was bunk, it has to do with the multipliers used, some just fit and some don't.
