Hi All,

I've just built my new home server. Main components are as follows:

Ryzen 2700X @ stock
VULCAN TUF GAMING ALLIANCE 16GB (2X8GB) DDR4 PC4-28800C19 3600MHZ using XMP profile 1
Gigabyte 450 AORUS M

So I've got it booting and everything is working fine, the memory is working at the full 3600Mhz but it's not running in dual channel mode. CPU Z reports single channel and I've benched the whole PC and the RAM speed suggests it is running in single channel http://www.userbenchmark.com/UserRun/11352905

The following is an excerpt from the manual:

This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual Channel memory mode will double the original memory bandwidth. The four memory sockets are divided into two channels and each channel has two memory sockets as following:

Channel A: DDR4_2, DDR4_4

Channel B: DDR4_1, DDR4_3

I'm using slots 2 and 4. Am I doing something really wrong here? This is far from my first rodeo but I've not used AMD since my AMD 64 3700+!!

Thanks!
 
Any problems with this RAM since you’ve had it?

Seems considerably cheaper than most other 2 x 8Gb DDR4 3600 kits and I’m currently shopping for my 2700X build.

In fact I could pick up two of these kits for the price I was originally going to pay for a single kit.
