Optiplex 990 RAM Compatibility
Could you tell me which are the Memory Supported for Optiplex 990 Mini Tower?
Reading the manual it seems only DDR3 Speed 1333 MHz therefore PC-10600, from Crucial seems to be compatible also with DDR3 Speed 1600 therefore PC3 - 12800?
They are both compatible?
Where we can find complete information about RAM compatibility for this Opliplex and in general for other Dell Product?
Sometimes the manual are not so complete....

Below is the published spec's from the Dell manual. I tried to get the Crucial list for this model but the Crucial site is not working properly. Keep in mind its best not to mix memory, even if its the same speed. Best to only install same memory from same vendor.

The crucial site is now up, below is their listing. Note they list 1.35V memory and the Amazon memory you link is 1.5V and may not work or work properly.

I recently updated the bios to ver. 24 and installed 32gb ram with my dell Optiplex 990 SSF. Everything is running fast and good now. Photoshop and lightroom opens supper fast.
Here is the link to the Ebay buy: https://www.ebay.com/itm/Transcend-8GB-2Rx8-DDR3-1600mhz-PC3-12800-UDIMM-Memory-FOR-PC-Desktop/223839329356?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
