Hi,

I've an Optiplex 3080 Micro with 8 GB of RAM. The PC tools says it runs at 2666 mhz, but I've opened it and took a picture and it has installed a 3200 one, Kingston 8GB 1Rx16 PC4 - 3200AA - SCO - 12  is on the tag.

Now I want to add a second 8GB bank, if I go on the Kingston website it only suggests 2666 mhz ones for the 3080. Crucial has both 2666/3200 (different prices).

Should I put a 3200 one in or a 2666 will work the same since the PC doesn't run at 3200 mhz anyway?

Thanks for the help.
