Question Is my memory set up for quad channel? Checking with CPU-Z

[Balic Blackthorn]

So, I bought my components, but a friend actually put my pc together (getting a bit older, don't trust the old manual dexterity as much these days). I have 4 16 gig ram sticks, but it occurred to me to check if they were actually set up for quad channel (my board, X399 Tachi, does support that). The easiest way I found was to download CPU-Z and check that way.

Tried to just post a screenshot of the readout, but it's not cooperating. So, on the memory tab of CPU-Z, it lists "4 x 64 bit" in the "Channels #" box.

I am not sure if this is telling me that this is in quad channel mode, or if I have 4 sticks all in single channel mode.

Anyone familiar with this program know? Or is there another program I should use to check this?

Not a huge deal since I haven't had performance issues, but since I'm going to have a new internal SSD plugged in in the next few weeks, might as well have the RAM rearranged to enable quad channel if it isn't already.

Many thanks.

What ram kit do you have? Which slots are the rams populating, per the motherboard's manual/PCB labeling?

It's running in Quad channel. DDR4 uses 64-bit data channels.

Of note whenever you upgrade to a DDR5 based system, each RAM stick is 2x32-bit channels. So you just have to divide the multiplier by 2 to verify it's running in the proper mode.

4x 64 bit is Quad Channel, and on the SPD tab you can see which slot every DIMM is in and they should be in either every odd or even slot in the list if you want to verify.

Thank you both for the replies. I saw screenshots of people using that same program to verify dual channel and it actually said "Dual" in that box, so I wasn't sure if it should be saying "Quad" to indicate quad channel or not.

An option....install and run speccy.

On this pc the first screen shows in English 'dual channel' for the ram.

The number of memory channels is dependent on the CPU. Someone could use that memory on a desktop CPU and it would be dual channel.
Follow the motherboard manual for the proper order to populate slots and you will be good.
