Question RAM Working Very Below Speed

[jets660]

Can someone explain to me if this makes sense? I have a ddr4 2666 8gb, should my DRAM speed be only 665?
And if I'm looking to add another stick, what should i get?
Thanks

What makes you think DRAM speed is only 665?

Specifically.

On CPU-Z it says DRAM is 665.5 which if i understand you multiply by 2 and get 1,330.
Isnt that only half speed

What does task manager/perf/memory show for speed?

What does task manager/perf/memory show for speed?

Thats shows 2400MHZ, which doesn't line up with anything.

2400 is the default speed for that cpu.
You have 2666 ram which clocks down to 2400 speed.

If you look in your laptops bios you may be able to set the ram speed to 2666/7.

then why is my DRAM speed at 665?

Unfortunately i have a Lenovo and the bios for the thinkpad doesn't have options line xmp in it,
its a sore topic for many Lenovo users

Does the bios at least tell you what speed your memory is running at?
