Ryzen memory speed/latency help

[PyroTheWise]

I have watched videos and read some articles but the following still confuses me....

 

I am building a Ryzen 5 3600 cpu/5700 XT gpu/Sata HDD and 16GB of memory (2 8gb sticks).  I don't have an unlimited budget to build this computer so i was wondering how much of a performance hit I would be taking using a better latency 16-18-18-38 ram versus slower 3600 at 18-22-22-42.  I know I could throw some more money and get 3600 ram at 16-19-19-39.

 

I don't understand that those numbers mean (i.e. 16-18-18-38) in relation to true performance gains/losses.

 

Can you please provide your opinion on this 1000 US dollar PC gaming build?  Should I work on stretching the budget even further to get better 3600 MHZ ram at 16-19-19-39 or keep 3200 ram at 16-18-18-38.

Depends on the task, really memory sensitive ones can maybe drop like 1% performance, but most of the gains comes from higher frequency. That's why you shouldn't consider 3200MHz in most cases, apart from Crucial ones because Crucial is owned by Micron and Micron only has 1 die (Micron Rev.E) that can do over 2933MHz with the factory memory profile. Besides you're probably still getting the same die types on different 3600MHz kits (Hynix or Micron) so you could try tightening CL18 kits to CL16 with a bit more voltage.

Yeah, I have no desire or plans to mess with the Infinity Web ( I think that is what it is called ).   I have watched videos on how to do that stuff but I also realize that is too much for me to take on right now.   I just want a stable good performing system.

 

So does 16 based 3200 better than 18 based 3600?   (no infinity web changes)

no it's worse, Infinity Fabric is by default, set to half the memory data rate automatically up to 3600MHz.

So I should definitely get 3600 MHZ ram then...  Okay, thanks for the information.
