Crucial RAM works fine plus they guarantee 100% compatibility and a limited lifetime warranty, but I am not sure why you picked the single memory module which you have to buy two versus the 16GB kit (2x8GB). I am sure the Dell product is fine but you can purchase the Crucial 16GB kit for less than the cost of a single memory module from Dell.

I’ve just upgraded my 8930 from 8gb to 16gb with Crucial memory. Part number is showing as CT8G4DFS8266 - DDR4-2666 UDIMM. So looks to be the same as what you are quoting.

I dropped it in and it works a treat with no issues. 

Thanks....appreciate the confirmation

Thanks for confirming the quality and compatibility Vic.

I would purchase the 16GB kit (2x8GB) that you referenced in the link, I just grabbed the first link from the Crucial site when I was looking at it to post the question about it here.

The difference in pricing between Dell and Crucial is a definite factor, knowing now that Crucial stands behind the quality, compatibility and offers a limited lifetime warranty, makes the decision that much easier.

Thanks again
