Desktop 3891 RAM Specs
Hello everyone. I have just purchased a Dell Desktop Inspiron 3891, Intel(R) Quad Core i3-10105 CPU@ 3.7 GHZ, 8 GB (4DDR) RAM (1 Stick), 1TB Seagate Disk hard drive, 64 bit, Windows 11 Home, on board Intel(R) UHD Graphics 630.
There is a stick of 8 GB RAM in one slot and the other slot is empty. I would like to add 8 GB of RAM to the second slot or maybe even install 16 GB RAM in both slots for a 32 GB total. I do not know what type of RAM to use. Two examples of types of RAM I’ve seen described for this desktop are 8 GB DDR4 3200 MHZ CL22 and 8 GB DDR4 2666 MHZ CL19. Could someone please let me know where I can get the specifications for the correct RAM for this desk top. I would appreciate any comments or suggestions you may have.
I have not registered this desktop yet but I’ll figure out how that’s done shortly. I do have a laptop in the Dell system.
Thank you for your help.

There is no mistake on the RAM specs. This web page at Crucial lists the RAM for the 3891 and the specs are the same as you have seen.

I bought CP2K16G4DFRA32A from Crucial, but that is not workable on Insiron 3891. The power light signal is 2 Orange + 5 white which means
unsuitable memory on 3891.
I confirmed with Dell service team, it's not Dell certification parts. They suggested using MTA8ATF2G64AZ. it's horrible news for me because Dell does not STOP Crucial from selling unsuitable memory to end-user.

You can purchase Dell oem ram from third party using memory maker model number. Crucial is typically not a Dell oem partner.
