Upgrading Memory (Ram) in a Dell XPS 420

by darrick77 / October 27, 2009 9:55 AM PDT


I have recently purchased some Ram for my dell XPS420

2x [Corsair XMS2 TWIN 2X2048-6400C4 2GB (2X1GB) PC2-6400 DDR2-800 CL 4-4-4-12 240PIN Dual Channel Memory].

I removed the current memory from my computer (2x 1gig) and went to put in the 4 new peices. My comp beeped at me then didn't start up.

I removed 2 of the new sticks and it worked just fine.... I thought that I may have installed the ram wrong, so I tried putting the extra ram in again only to see the same problem.

I then thought that it might be Faulty ram, so I switched them around and again it worked with 2GB; however, not with 4.

Running Windows 7 64bit

Any help would be greatly appreciated.

The most beautiful phone ever has one wildly annoying issue

The Samsung Galaxy S8's fast speeds and fantastic curved screen make it a top phone for 2017, but the annoying fingerprint reader could sour your experience.
