C14 and C16 DDR4 Ram

[Azakius]

I’ve just decided to add an extra 16GB ram to my system, ordered it then realised the ram I have in currently is C14 and the new stuff is C16, can I mix them? It’s the same brand and speed, 3000mhz Trident Z RGB.

I think you can but it will match up with the slower speed RAM so all of your RAM will be running at CL16.

Will I notice that at all?

In most use cases and workloads, no.

well its not a given that it will work but it could work 

 

and if you gonna realise it.. depends on you really the difference is not tremendous though on any case.

Debating just cancelling the order and picking up 32gb Vengeance LPX instead, at least I know that’ll work from the off. What’s the chances of it not working?

On Intel it should work every time you do that. I suspect you're not overclocking the sticks yourself? Since the whole point of 3000MHz CL14 is the fact that it's Gskill's lowest bin (i.e. cheapest, tho not always the case) of half decent Samsung B-die while 3000 CL16 isnt

No I don’t think so. It’s kind of like trying to notice the difference between a 120hz monitor and 144hz monitor. You know there is a difference but in real life use it’s almost impossible to tell. Linus actually did a video about it and found out even pro e-sports players had a hard time telling the difference. It would be the same with RAM.

Yeah, I’m just using XMP to overclock to 3000Mhz in the bios, not manually doing it myself.

The difference in real life application is like the time it takes to blink. I checked out some forums and benchmarks and it’s literally in the 1/100ths of seconds or milliseconds. So if you’re willing to wait the time it takes to blink, then the CL16 will work just fine.

 

Side note: I have 32GB (16gb x 2) of  Samsung B-die Corsair Dominator Platinum RGB 3200 MHz RAM that is CL16 just like yours and I’ve tried lower latency RAM and didn’t notice any sort of difference. The benchmarks noticed it but I didn’t. I’m also using high end components like i7 8700K & 2080 Ti so it’s not like my components are limiting it or can’t keep up with it like a lower end PC (Intel celeron , no GPU, etc.,) would probably do.

Its not so small because it all adds up cl 16 means 16 ns but that's like the cas call latency that happens in every cycle and there are thusands of them happening per second...

 

here for example difference in games 

 

but I agree that it's miniscule... but its not like not noticeble at all some of the examples above though have like 5-10FPS difference so yea you could tell that difference although subtle

It might be noticeable if you’re really looking for it, but I think if you took someone and sat them in front of a PC playing a game with CL16 and then swapped in CL14 and asked them “Which one is better?” they wouldn’t really be able to answer unless they were just guessing.

 

I definitely don’t think it’s worth paying more for though when you could use that extra money to get like an SSD or a more powerful CPU/GPU and get a much more noticeable performance increase. Like if you went from a 2070 to a 2070 Super or from an HDD to a SATA SSD, let alone an NVMe SSD.

 

Thats just my opinion.

I agree that if there are budget constrains you should aim first to get better GPU/CPU but cl and speed adds up 

 

for example if one has a igpu cl14 3200 could mean 30 FPS instead of 25 for example..

 

It also adds up in professional usecases where ram is used a scrab or in-general whenever the workload needs time to be processed and ram plays a part it could mean that youll finish something in 8 hours instead of 9
