Pros: I didn't buy them here at Newegg, but I just installed two of these sticks into my 3 years old Dell XPS 8300 (which is technically DDR-1333 spec, while these support up to 1600). I tested the 2 new sticks with the Memtest (version 4), along with the two of the 2GB that came with the system (removed 2 2GB), at speed of 9-9-9-24. It took about 1.5 hours to thoroughly test the 20Gigs (I wanted to test both for compatibility).

After one full round of the memtest test was successfully concluded, I booted into Ubuntu, was OK (see 20Gig). Then I booted into Windows (Win7 Home premium), Windows sees 20Gig, but only gave me 16 but that was an artificial limit by the OS. So, It works good! The XPS 8300 wasn't on the "Officially" support list, but it does work.

Cons: No Cons.

Other Thoughts: I'm running 2nd Gen i7-2600 / XPS 8300 (was 4 x 2 Nanya GB Sticks). Put two new sticks of these in the slots labelled 1 & 2, and they work fine with 2 original sticks left in slots labeled 3 & 4

I hope this will help other XPS 8300 owners who's looking for an upgrade, but don't see the XPS in supported system list.

Pros: Cheap Price, Fast, Good quality

Cons: None that I can come up with.
