Need to upgrade Ram on Acer Nitro 50 N50-620-UA14 Desktop

PCer

Bought the Acer Nitro 50 N50-620-UA14 Desktop at BJs today. Of course, I want to upgrade the RAM.

Search online for Acer Nitro 50 N50-620-UA14 Desktop and I'm given links for the Acer Nitro 50 N50-620-UA91Desktop.

When I do find info/specs on the Acer Nitro 50 N50-620-UA14 Desktop I see only 2 RAM slots. Um... no, my PC has 4 slots for RAM. Do I actually have a UV91?

Another confusing matter. The online specs for the Acer Nitro 50 N50-620-UA14 Desktop show RAM is DDR4-2666. However, pulling the RAM installed in the Acer Nitro 50 N50-620-UA14 Desktop I just bought is DDR4-3200. Which is correct? 2666 or 3200?

Also, does a motherboard manual exist for the Acer Nitro 50 N50-620-UA14 Desktop?

Thanks.

Yes your N50-620 has 4x U-DIMM slots and these are all the specs and guides from the Acer SG for the Nitro N50-620s desktop memory, follow this guide and only buy the below recommended ram modules, as Acer has tested the below spec ram to work 100%.

With the Crucial scan (do it for your Acer Nitro 50 N50-620-UA14 as it will probably give you their Acer NITRO N50-620-UR13 results) and the UR13 and your UA14 have both got 4x DIMM slots but Crucial always only recommends 2x ram module upgrades, as for the Acer NITRO N50-620-UR13 | Memory RAM & SSD and it’s the same as your N50-620-UA14 Crucial guarantee their scan and for this desktop to work with 2x 32GB DDR4-32000 CL22 or even up to 2x 32GB DDR4-3600Mhs CL16 Ballistix type of their ram in dual channel which the DDR4-3600MHz CL16 is a bit suspicious as I don't think that the N50--620 has the bios settings to utilize this ram speed so its a waste of money upgrading to this ram!

Also, Dual Channel Ram is known not to be as efficient as Quad Channel Ram (yes its contentious but I prefer Quad Channel) as Acer suggests its max capacity of 64GB total to be run in the Nitro N50-620 desktop with 4x 16GB in DIMMs 1 to 4 at DDR4-3200MHz CL22 ONLY which will operate in Quad Channel for a reason which has been tested and proven. Good luck and hope this has helped you out to make the proper upgrade decisions for whatever your ram capacity upgrade is.
