Is my memory at 3200 mhz?

[kage65]

Have asus rog strix z370 e gaming

corsair ddr4 3200 memory

intel i7 8600k

 

My bois says im running 3200 speed in one area and 2133 in a different area. How do I know if I'm really running in 3200? Tksd

CPU-Z. It will either say 3200 or 1600, either one means you are running at 3200 MHz.

Boot into Windows, run CPU-Z (download it if you don't have it installed already) and tell us what it says the speed is in the memory tab.

Yep, it's running correctly. RAM speeds are weird, but they are running at 3200 MHz.

Interesting, that bios screen is confusing. Also if its running at 3200 why does cpu z show 1599? tks

It should be. The XMP profile has been set correctly.

 

I expect the first number in the Information is possibly just a label.

The DRAM numbers tell the default spec of the RAM.

The XMP number tells the modified profile that the RAM has been set to.

Maybe funny OC settings?

Doh moment. I read it as being 101mhz off, not 1mhz.

DDR = Double Data Rate. What CPU-Z shows is the actual clock speed of the RAM, but DDR means that two operations are performed per clock cycle, which would be the same as 3200MHz if it were performing a single operation per cycle. It's an effective clock speed.

 

3200MHz sounds better than 1600MHz, so the effective clock speed is quoted. 

 

EDIT: As for it being 1599, it's likely something the system did for timings or something. For all intents and purposes, it's 1600MHz.
