The correct MHz

[Oakmeal]

How do i know i know if my 32gb ram how do i know if i am running at the right speed i looked at it but i am not sure what i am supposed to be looking at or what numbers are good and bad. I am using corsair Vengeance. It is DDR4 With a MSI z390 Motherboard

Go into CPU-Z and see what it shows in the memory tab. There a section 'DRAM frequency's which shows something in MHz. Double that (we're talking about DDR4 here. DDR = dual data rate) and that's the speed it's running at right now.

 

If you haven't done any manual tuning or turned on xmp, it will likely be running at 2133mhz.

 

Is that the right speed? It depends. Is it actually rated for higher speeds? (All DDR4 is the same, some are just higher quality and thus support higher speed). The box might say something like '3000Mhz', which is what the manufacturer tested and rated these sticks of RAM at.

 

Go into your BIOS and change the ram settings. Check your motherboard manual (found under the product page > Support > Downloads section) and check what it says to do there. Usually you can turn on XMP, but some boards have helpful features to tune it themselves 

 

Faster memory generally helps performance on most systems, more so on AMD system though (but why run at a lower speed when it can run faster??)

it's at 1066.7 MHz not changing so should i enable XMP?

Sure. It means you're getting 2133MHz data rate atm.

I turned it on and it it only went from 1066 to 1500 And i dont see that much of a difference.

Means you're running 3000Mhz now, normal PC usage you really aren't gonna feel any difference. 

 

If you're gaming or running benchmarks, then you'd see the difference more clearly although I think for Intel its abit less obvious than AMD.

You won't see a substantial improvement by eye, but by tests it might be seen. Personally on my AMD system in gaming the faster memory improved the min. fps numbers (actually, there was stuttering at 2133mhz).

 

On another AMD APU system it improved the Cinebench CPU and GPU scores by a bit.

The improvement can be as low as nothing or as high as 10 or 20 %. But why let that extra performance (and thus faster render times.. more fps.. etc.) Go to waste?
