Hi, my ddr4 3200 kit of ram is only running at 1600MHz even tho it is set to 3200 XMP mode in the bios .

specs should be below

Sounds like you're looking at the data rate in cpuz. Your ram is double data rate so multiply the reported speed by 2 giving you 3200mhz

Serious software reports I/O bus clock, and DDR memory has doubled data rate to I/O bus clock so 1600MHz I.O bus clock means 3200MHz data rate.

Interesting DDR4 Shouldn't be running that low. btw, Your specs aren't listed. DDR3 would be running at 1600Mhz. Could you show us pictures of your bios settings?

Servers do run DDR4 as low as 1600, though that's back when it's first released.

Sounds like you're looking at the single channel memory speed in cpuz. If you're running in dual channel you multiply the reported speed by 2 giving you 3200mhz

You know what? Single channel and dual channel will show the same frequency in CPU-Z. This is just wrong.

Oh wow I should get some sleep I meant double data rate not dual channel >.< I'm gonna edit that so I don't confuse people in the future. Thanks.

Why do you think that is ?

Because DDR. Back in the past we have SDR memory that has the same data rate as actual operating frequency, in order to market DDR's speed advantage they start talking about data rate only and ignoring I/O bus clock even though both exists for the whole timg\e

So is my memory running at its maximum speed?
