how much better is ddr3 than ddr2

[LucasXD]

how much better is ddr3 than ddr2 on a scale of slightly better, moderately better, and a lot better and why?

honestly I cant tell a difference in my computers. I ran mid grade ddr2 and ddr3 in a socket 775 computer with the EXACT same hardware (except the motherboard) and I was unable to to notice any improvement. same goes for the ecc registered ram i have used.

DDR3 today is clearly faster than the fastest DDR2 that was ever made. But when the switch from DDR2 to DDR3 first happened, there was not a perceptable increase in performance.

The same thing is happening again right now as DDR4 has started replacing DDR3. The speeds of DDR4 are about the same numbers as speeds of DDR3, but there appears to be almost no change in performance.

Over the next few years though, if some other form of memory doesn't change things up, DDR4 will eventually be much faster than the fastest DDR3 that we can get now.

It's more depend on what type of rams your mobo support..

If it support both I would go with max supported DDR3 (speed)..
DDR2 now days is quite rare, and the price is usually high for it's performance
(since most of them old stock, not produced anymore)
