I just upgrades to 4 GB DDR2 667 5300 but it says i have 333MHZ

[Shpati]

I just upgraded my memory for a Dell E 510. The one I ordered was Crucial 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) Dual Channel Kit Desktop Memory. The CPU-Z's memory tab says I have all those specs for my RAM expect I have 333 MHZ not 667. How can I fix that and make it 667. Also is there a memory scan I can do that will see if my memory has any errors. Also is there somethings I should do to make my RAM better. I heard some people talk about it but do not know what they are talking about (like change the timings or something). Here are the CPU-Z's report below. (I just copied pasted what I thought was important, tell me if you need other information). Thank you guys for reading!

Your memory is running at 667 because it is in dual channel mode (333 x 2).
Each channel is running at 333 and together they are 667.

 

[roadrunner197069]

^ Kinda. The channel has nothing to do with it, right idea though. DDR2 is double pumped aka 333x2= 667. It is running 667.

My DDR3 is running 1440 and it shows as 720 in cpu-z, it is just how cpu-z does it.

alright thank you guys. u helped alot.

+1, RR is right^.
It is running the right speed because it is DDR memory (Double Data Rate)
Dual Channel is a mode the memory can run in, something a little different.
