ram speed

[william97]

i bought msi b350 mortar and ryzen 5 2400G with ram 2400mhz as the seller said that the 3000mhz will crash with the mobo (in the manual it really say that the max speed is 2666)but now i see on youtube that its possible to run even 3200mhz with the b350 (not sure if it is the same one) 
my question is does it really matter??
and if so ... can i overclock the ram speed to maybe 2800 ?! (psu:bitfinix bpa 600w ... should i upgrade it?!)

The seller is just dumb, the max officially supported speed is 2666MHz, but you can go much higher than that. Speed does matter a bit for Ryzen, you can get a little 10% bump in some cases for what I've seen, but no big deal if you're running fine. You probably will be able to OC it to 2800MHz, try it out, and the PSU doesn't matter because the consumption is minimal.  If you use the Vega 10 as GPU, it will matter much more, if you don't use the iGPU, in which case you should've bought the 2600 instead, it won't matter much, as I said.

if i OC the ram to 2800 will i have any trouble ?! and does it warth the effort and the money to change it with the 3000 (comared to the 2800) ?!

another question ... in the future if i need to buy more ram can i get higher speed or iam limited with the 2400? (iam using 2 ram slots and there r 2 more slots)

If you get to 2800MHz, you'll be alright, not much difference to 3000MHz, which is usually the sweetspot (also 2933MHz). As I said, the speed will matter much more if you're using the integrated graphics, and less if you're using a graphics card. If you install another kit in the future, both kits will be set to the slowest speed of the two, so 2800MHz if you can overclock and 2666MHz if not. Something that also matter a lot is the CAS/CL timing, a 3000MHz RAM with CAS15 is faster than one with CAS18 or higher, for example.

in general on ryzen you want 3200, but for a 2400g i'd recommend just overclock it to whatever is stable and call it there, don't bother with 4 sticks in the future.

some sticks will need manual memory overclocking if the XMP profile doesnt work.

its cl17 ... and yes i will use the igpu for a while

mine is crucial 4gb ddr4 2400mhz cl17 1.2v (2x4)

So that's your base, try to see if it boots at 2800MHz, if not, leave at 2666MHz and try to lower the CAS to CL16, if not, CL17 it will be. It's a pretty bad kit of memory for Ryzen, specially for APUs like yours.

I don't fancy your chances to hit 2800. Crucial sticks exclusively use Micron memory dies, which are the worst among DDR4 in terms of overclocking.

 

I'd rather you start at 2666 with the same timings you have now and memory voltage at 1.35V. If it crashes, stick to 2400 and tune the timings instead.

i will try to afford changing it with the 3000mhz ... if it's not possible i will follow ur instructions to OC ... thank u very much u werw really helpful
