Best result that i can get with stable overclock was DDR4-3800 CL16-19-21-32 @1.42v. So basicley it's slightly faster than Samsung B Die when XMP is enabled for DDR4-3200 CL14 kit and DDR4-3600 CL16 kit. And maybe it's on par with DDR4-3600 CL15 samsung B die kit when XMP is enbled.

3600 CL 16 Bdie seems a little faster. I'm guessing read/copy are just slower period on 1 CCX chips didn't really pay attention to any reviews on that. I know write speeds are way slower.

Why is @Verbatim write speeds so much lower.

1 ccx Ryzen 3000 chips suffer from half speed writes 3600-3800X.

Part of the reason I went with a 3900X although it doesn't really show up in any benchmarks gaming or otherwise I've seen as being a limiting factor.

Maybe someone with Ryzen 3600, 3700, 3800 can show numbers ? Ryzen 3900 boosts ram significantly. It's recommended to turn off PBO because that may show different result.

Keep in mind, he's on a B450 board and there seems to be a slight memory disadvantage on those.

Yeah, the Benchmark in general isn't a really good representation of performance. I notice more doing CPU limited gaming benchmarks to know if what I did to my ram makes a difference or not. even with a 2080 ti in most games I've tried the gpu isn't fast enough to show a difference past 3200 14-14-14-28.


But the bottom line of this whole thread really is CJR can be really good if you get lucky... B die just takes the luck factor out of it.

I paid $186 for for 32GB of CJR at 3600 16 19 19 19 39. B-Die was $50 more at 3200 14 16 16 16 32 I think.

EDIT: According to DRAM Calc, I can do 3800 at 16 16 21 21 32

I think you'll find that should be 16-21-16-21, or maybe a bit tighter in the 21's.

It's not really about luck, but yes B-dies can run tighter timings, but generally costs a lot more and the question then is if you feel the extra cost is worth it or not.
