Purchased 2666MHz RAM, but is running at 2133MHz even though original RAM is running at 2666MHz

Hi:

The only suggestion I can offer would be to buy the same Samsung memory that is listed in your screenshot.

I know it is a waste of money, but that is the only way you are going to get the memory to run at 2666 MHz.

I entered the part number (please double and triple check my work) and found some modules on eBay that are reasonably priced.

HP does not sell the memory...the 8 GB part number is 934254-800

Hello
sorry, but unless I did not see / understand well ..
It matches my thought, you don't have the right modules it looks like
in the image you give we can see:

SAmsung DDR4-2666 / pc421300  8 gb/4gb

Product page :

• Amount: 12 GB
• Speed: PC4-21300 MB/s
• Type: DDR4-2666

but 

PNy electronics

DDR4-2133 / pc4-17000  8gb/8gb

So this is the first time I see this anyway
Mods may be the right ones, but not at the right frequencies
but it seems to me that if we use a specialized software, it must recognize if they are PC4-21300, except here, it is not the case.
I can not give the capture, but it is the case on my old pc, I used the modules of an hp HS, of different frequencies and models
They are properly identified as they should be, and the computer is running at the lowest frequency as it should be!
So are you sure that the modules are what they should be?
But yes, the best is to use the same ones, but is it really noticeable, my computer, works quite well while the memory is not at its maximum frequency, I did not find much difference, except that 'he has more ram on this side that is noticeable
