[SOLVED] Faster mem wil CL19 or slower men with CL16?

[Mugsy]

I'm in the process of upgrading (3rd gen Ryzen & MoBo with X570 chipset) and in need of new memory.

I'm wondering if it would be better to buy 4400MHz memory (the MoBo supports it) with a CL of 19, or 3600MHz memory with a CL of 16? (the 3600/CL16 is slightly more expensive, making me wonder if it's the better way to go?)

TIA

3600 Cl16, I'm not sure that 4400 is achievable and over 3766MHz it's very little to gain due to increased memory divider and an latency.

Thx for the reply.

Actually, I'm more concerned about being "future proof". I plan to eventually upgrade to a 4000 series Zen 3 cpu when they come out which are more likely to support 4400MHz dram natively.

So my concern isn't so much whether I can achieve 4400MHz now as whether faster 3600MHz memory will perform better.

This is sort of half my thinking when I bought my first kit of Patriot Viper Steel Series DDR4 4000, which uses Samsung B-die. In Oct 2019 when I bought he 4000 kit for $105, it was cheaper by $25-35 than 3200 and 3600 kits using B-Die. I knew I would have to manually overclock them though, because they don't have XMP settings for 3000-3600MT/s exposed in the bios.

So my advice is to only buy the DDR4 4400 kit if you are comfortable with manually tweaking ram timings now and in the future. If Ryzen 4000 only supports memory speeds up to 4000MT/s with 1:1 Infinity Fabric, you may be better off spending less for a DDR4 4000 kit, which should have XMP setting for 3866 if 4000 doesn't work.

Thx. Good information.

I'm currently looking at 3600MHz memory with CL of 16, but I don't know how much of a performance hit it would mean vs 4000 ram with a CL of 19 (if any)?

If it's just for games, you are not going to notice any real performance hit or increae either way, at least for games already released. Most games are not affected by ram speed past 3600MT/s. Also you will probably be running your 4000 kit at 3866 CL18 or 4000 CL20, unless you have gear down mode off (allows you to run odd cas latency) to run CL19.

Thx. I don't play a lot of games (nothing too recent or demanding). I mostly do video/audio editing with lots of compression.
