Doubts about different CL RAM

Hey,
So my local hardware store is having some promotions this weekend and I got a doubt to ask the experts of the community.

 

My current setup has:

Intel® Core™ i9-7900X (13.75M Cache, 4.30 GHz)
Asus ROG STRIX X299-E GAMING

2x G.SKILL Trident Z RGB 16GB (2x8GB) DDR4-3200MHz CL14 (F4-3200C14D-16GTZR)

I was hoping to improve my System from 32GB (4x 8GB) to 64 GB, but the "F4-3200C14D-16GTZR" kit is always selling about 260 EUR (so 520 EUR total).
Today I saw a promotion on "G.SKILL Trident Z RGB 16GB (2x8GB) DDR4-3200MHz CL16" (F4-3200C16D-16GTZR).

 

As far is I know, the only difference is between CL14 (14-14-14-34-2N) and CL16 (16-18-18-38-2N).

And the CL16 is seeling about 170 EUR (340 EUR total)

Would it make it a noticible inpact on my performance?

Regards!

1. why do you even need so much RAM?

 

2. The performance difference wont be noticeable with XMP profile, but further overclocking could be affected. 3200MHz CL16 kits are often using Hynix MFR/AFR dies which do not overclock as well as Samsung B-dioe found in 3200MHz CL14. Those are the worst Samsung B-die btw, but still better than Hynix stuff.

Short answer: no. Long answer: It largely depends on what you do, but CL is latency. Higher latency = slower ram. If you are doing intense professional video editing, you'll probably see some sort of difference between the two. It's a very small difference, but still might be noticeable depending on what you do. You can also overclock the slower ram to have faster timings. Ultimately, if you have money to blow, the obviously get the more expensive one, but if you're strapped for cash, get the cheaper one.

Hello,

Honestly, is more to get all of the ram slots populated with those sweet RGB lights :P

Besides that, I work with databases (MySQL), Adobe Premiere (Video Edit & Export) a bit of Cinema 4D / 3DS Max and Gaming.

 

And I don't really intend to overclock the RAM, never had the need for that.

 

Considering all of this information, is better to buy the cheaper one (using XMP) and save the 180 EUR?
