Ryzen ram

I think I might have screwed up with my ram purchase. Basically bought a pair of 8GB Corsair vengeance rated 3600mhz CL18. I heard that Ryzen runs better with faster ram but mine is CL18, as far I've read it's slower when rated highest?? For example compared to cl16?

Should be good enough for c16 with a bit of +v

Which Ryzen CPU is this for? The new generation seem to be less fussy with RAM and don't lose/gain anywhere near as much as the original Ryzen chips with different memory speeds.

Sorry I'm dumb. How do I achieve this exactly?

3700x

Dependant on the motherboard, enable D.O.C.P profile (could be called XMP) in the bios.
This should enable:
3600MHz, 18-19-19-39, 1.35V
so your goal would be to get something like 16-16-16-36 and found the lowest voltage it would work. Test for stability few pages up is the great advise post about how to do it:

Many thanks! Is it a big deal if the system is simply for gaming???

You can easily run the stick at CL16. Just set XMP on your motherboard so that the RAM is set to 1.35V and then change the timings manually to 16 16 16 or 16 17 17 and you should be fine. Run memtest for a few hours to confirm stability followed by a few games.

Though i must say there is not much difference in games whe you do all this. I changed my 3200MHz CL16 stick to Cl14 and also tried 3600CL16 but no difference.may be max 1fps difference in benchmarks. So honestly not worth it in my opinion. Just leave it as is if you wish.

Yeah pc will be purely for gaming. Thanks for the advise fellas
