ram Which RAM would be better

[Shadow_Monarch]

I'm trying to upgrade my build and at the moment I'm going to upgrade my RAM kit and was wondering which one would be better

1. 32GB (2x16) C18 3600Mhz

2. 32GB (4x8)   C16 3200Mhz

which one would be faster/better to use in a build for gaming and game design

[Eigenvektor]

The first one is faster (3600 vs 3200) and has the same latency as the other one (CL18@3600 is equivalent to CL16@3200, 10 nanoseconds)

 

☆edit: Depending on the CPU, two sticks is also easier for the memory controller to run. It may not be able to overclock to 3200 with four sticks.

Make and model of the ram and the cpu you want to use it with?

the difference is almost 0

 

but you can get a 3600mhz cl16 kit but dont expect more than 1% performance upgrade

First post, same question different parameters. Would it be within the etiquette to ask it here since you guys are engaged with this thread already, or should I create a new thread?

i7-7700

Z270 Asrock mobo

4x8GB Avexir (Hynix mystery die single rank) 2800Mhz 15-15-15-38 1.35v

 

2800Mhz 13-15-15-28 vs. 3200 Mhz 17-19-19-38?

I also managed to get it to 3333Mhz stable on 1.4 volts and 19-21-21-38, but I suspect that config is inferior.

 

True latency is lower on the 2800Mhz but RAM is also meant to move bytes, not just access addresses quickly, so I'm not sure.

[Talamicus]

The AIDA bench shows better latency and throughput with the 3200Mhz 17-19-19-38 than the 2800Mhz 13--15-15-28 by the way, which doesn't make sense latency wise. The CL13 hovers ~55ns and the CL17 around 50ns.

[Tonyx]

according to ram cl calculator 2800 cl13 is better than 3200 cl17, of course 3333 cl19 is the worst one

 

for gaming lower latency is better than more bandwith, for example dual channel is better than quad channel because quad has higher latency but a server dont need extremly low latency so for a server quad or eight channel is better

 

just try a game benchmark with different ram settings, i squeeze few extra fps moving from 1600mhz cl11 to cl10 and then to cl9 (i have ddr3)

Corsair Vengence pro 32GB kit

and at the moment a Ryzen 3600 but looking at upgrading to a 3700X
