Watch Question

If you look round for brandname DIMMs - Crucial, Kingston, Samsung, HyperX you are guaranteed a better product.

The main requirement is that they meet these specs - 1600MHz DDR3 Non-ECC  and maximum of 2 modules.  What you have listed above will suit.

Where you buy them from will not affect what you get - It's price vs convenience....

Hope this helps

so the ram you selected has a lower speed - but probably works
why probably ?  some boards are very picky about ram model and brand - so test it out

the guaranteed working ones are on the vendors ram list

Crucial's website lists that RAM as being compatible with the 9020, so that will be fine.  

I presume you've considered whether the new sticks will be added to existing ones, or will replace them?  If they're adding, you obviously need enough empty slots to take them, and I'd also make sure that they were the same speed as the original ones - the system will still run otherwise, but the memory on all banks will be limited to be as slow as the slowest stick you have fitted.


Is there a way to find out what kind of RAM stick is already installed (speed) , without the need to remove the stick to look at it?
Some software that checks all this?
Yes , it will be addition to an already existing 4GB stick ..

Crucial's website also has a scanner that will tell you what you have, and also what's recommended to go with it:


will 2 sticks of 4GB , and 2 sticks of 2GB work? or all 4 sticks need to be same size

normally - they should work together
but as said - you cannot be 100% sure, because some boards are picky about ram
best lookup what Dell says for ram configurations - see the manual also
