Dell Dimension E510 Memory Upgrade from 512MB to 4GB

Hello atving44

The cards should work fine, but only at 533 MHZ.

That is what I used.

Tom, I understand that the cards would work but I'm a little confused that they only will work at 533 MHZ. Just to clarify, does that mean the 800 MHZ memory cards won't work. A friend of mine has 2ea 2MB Memory Cards rated at 800 MHZ he's willing to give me but doesn't know if the higher MHZ would affect computer, Sorry I'm a little computer illiterate :emotion-4: 

Thanks for the explanation, I'm educated now! :emotion-1:

Hello!  Think of the memory speed as a car.  The car can only go as fast as it was built to go.  For the E510, it can only go at 533 Miles per hour so to speak.  You can place new RAM chips that can go much faster (the 800Mhz), but because your computers components were not built to go that fast, it will slow down the chips to 533Mhz.  Putting in the 800Mhz chips will NOT harm your computer, they just wont run as fast as they were designed to.  When I had my E510 I had 4 Gigs of 800Mhz RAM installed because it was super cheap to do that instead of getting the 533Mhz ones at the time, and all it did was slow the chips down to 533Mhz.
