AMD Ryzen Memory Speed Question

[JonathanH]

So I have a Ryzen 7 2700 and a MSI B450-A Pro motherboard. I'm looking for RAM and I know i want 16GB, but I need some help with finding the best price to performance in terms of RAM speed. Is the benefits of having 3400 or 3200 MHZ as opposed to 3000 MHZ worth the difference in price?

 

Thanks!

no they usually  cost much more and dont benefit you as much your best off getting a 16gb 3000 kit for like 100 usd

Your best best is 3000-3200Mhz at the lowest timings you can get, lower timings will be more beneficial then higher speed. Unless your doing video rendering, transcoding then higher speed will help. But don't sacrifice timings. Most kits can overclock at least 200Mhz without touching timings. I got 600Mhz out of mine with just a slight timing adjustment.

3000 only really helps you in Ryzen APUs. For a 2700, 2666 will perform just as good.

It be about a 4% overall drop in full load performance on avg. Depends on timings of the memory and user work load.

I don't think that 4% is worth the extra asking price....just my opinion.

I agree

If say OP was to keep a kit like this 2666 @ 15-15-15-35 1.2v

This would probably hit 3000Mhz at stock voltage and timings. Maybe 3200Mhz @ 16-16-16-38 1.22v

I have another question to the MSI B450 A-Pro Mobo. I got myself with a R5 2600 with a Aegis 2x8GB 3000mhz Kit. Works actually really good. But im concernd about "how" or even "wich" slots u should use for the dual Rams. is A1 B1 or is it A1 A2? I'm corrently a A2 B2 and so far no problems appeard. But im just concernd about the slot taking i did took.

reffer to the manual. it will tell you what is the best combination.

Yeah thats the problem.  It only "shows" (like an ikea manuell) how to get it into the socket. not more.

@Screaming Orca It's usually A2 B2.

It should tell you preffered stick configs.

 

Otherwise its usually dimm 1 and 3.

 

0 and 2 being empty.

Oh btw. How important is timing?  I tried cl12-14-14-28 , 2666; cl14-16-16-32 2933MHz, and 3200 with cl16-18-18-36.

 

Which would be the most suitable?  I know infiniti fabric benefits from bandwith, thus frequency, but how are tighter timings affect performance?

My 3600 14-15-14-14 setup is better than my 3200 12-13-12-12 setup.
