I am looking into building a system with a Ryzen9 5900x, and a X570S motherboard.
AM5/ZEN4 will take a while to mature, and prices are still too high for my taste.
And I hope that AM4 stuff will drop in price in the near future
The main question is that I’m looking into RAM, and found some G.Skill Flare X DDR4 3200MHz 2x16GB (F4-3200C14D-32GFX)RAM with CL14 (14-14-14-34) timings.
Also I found Mushkin Redline 64 GB 2x 32 GB DDR4 3200 Mhz with CL14 (14-18-18-38).
The price is almost the same, 64GB is somewhat overkill, but I want to pair the system with the best/fastest RAM possible to minimize bottlenecks.
Q: Is there any real difference in the timing of the 2 sets of RAM?
Overview of possible build:
Case: BeQuiet! Pure Base 500DX
Cooling:
BeQuiet! Silent Loop (either 240mm or 360mm depending if the 360mm fits in the front with a Push-Pull config with the radiator positioned with tubes at the bottom).
CPU: Ryzen9 5900x
Motherboard:
MSI MPG X570S EDGE Max Wifi
or
MSI MAG X570S Tomahawk Max WIFI
Storage: Corsair Force Series MP600 500GB & Corsair Force Series MP600 2TB (OS & Storage)
having more ranks will also improve memory performance, usually higher capacity ram is dual rank but not always true and sometimes small capacity is dual rank
OK. The G.Skill are single rank from what I can find.
The Mushkin RAM I’m not sure if they are single or dual rank.
I found this webpage with some info on RAM
Copy paste from the article above:
So, here’s what you should keep in mind:
4 sticks of single-rank memory (4x8GB, for example) gave consistently better results than 2 sticks on the same test bed.
2 sticks of dual-rank memory also gave consistently better results than 2 sticks of single-rank memory.
2 sticks of single-rank memory on tight timings (CL14~) grants a performance bump as well.
I think you can take the redline to 14-16-16 or lower, and that would grant a better benefit of doing the same on the flarex
assuming its dual rank
there are also tertiary timings that are undocumented, so one with the same primary timings might be better htan the other
hard to tell
both are pretty high end as far as each brand is considered
I lean more towards the redline as it wasn’t that long ago “you will never need more than 8GB”
I will be keeping everything at stick speed, I never do overclocking.
It is a general rule of thumb that I have, keeping it at stock speed to have the most stable system possible. It has worked out fine for me so far
But how much do the timings 18-18-38 mean in real life compared to the 14-14-34 ? The CAS Latency is the same.
