Im trying to upgrade my old ram Samsung 6gb (2gb x 3) 1333mhz 1.35v to Hyperx 8gb (4gb x 2) 1333mhz 1.5v ram. My desktop is a Dell Inspiron 580 with a Dell 0C2KJT motherboard. I looked up if the motherboard was able to and it said it was but when i install it i get stuck on dell loading screen. The ram works in my friends computer and my old ram works fine still. Was just looking to see if the motherboard could use the new ram or not and if it can how do i get it to work?
You'll have to ask Kingston about Hyper X RAM compatibility. This is an older, relatively low performance system that doesn't necessarily work with performance RAM that has aggressive timing. Older systems often don't work with high density RAM, which is likely what you've purchased.
If you want RAM guaranteed to work, try Crucial.
0C2KJT is Inspiron 580/580S motherboard aka DH57M02 Chipset H57 Socket 1156 you have to install LOW Density Compatible ram in Pairs.
