I have a Dell Studio XPS 16 (1647) laptop that comes with 4GB stock ram. I'm looking to upgrade to 8GB and while browsing the Dell website and TigerDirect for RAM sticks, they have these offerings:
I read a couple of forums trying to understand why one is PC3 and the other is PC1, and one user posted the following:
There is no such thing as PC1 DDR3 Memory. DDR = PC3
pc1-pc2-pc3 is ddr-ddr2-ddr3
It's not uncommon for online stores to post incorrect specs on their offerings. Can anyone explain if the Crucial Stick is actually PC3 (since it's clearly marked as DDR3), or if it's incorrectly marked as DDR3 and it's really just DDR?
