DDR4 vs DDR3 ?

[Dangatron173]

I'm in the market for an pair of 8gb(2*4gb) of DDR4 RAM. I dont want to spend over $100 for a pair of RAM.

Any good recommendation? I found the Crucial Ballistic Sport 8gb DDR4 2400

Is it faster than any good DDR3 RAM?

They're not exactly inter-compatible. If you're using a platform that uses DDR4, get DDR4. If you're using a platform that uses DDR3, you need to get DDR3.

 

The effective frequency is indicated by the number; any DDR[x] 2400 is the same as any other DDR[x] 2400, and faster than any kind of DDR[x] 1600.

What do you mean? CAS latency plays a big role in performance.

for gaming if you have enough gb of ram you wont notice a diffrence between ddr3 or ddr4 as well  there wont be any noticble diffrence between the frequencies of diffrent ram

Ehh RAM in general doesn't play a big role in performance...

 

And I did say any RAM with the same number has the same effective frequency, I didn't say overall performance, although I should have said "higher bandwidth" instead of "faster".

I meant CAS latency plays a big role in RAM performance, considering that's what we were talking about. Also, it definitely depends on what you're doing for the kind of performance gain you have. Even in gaming, it can make a somewhat noticeable difference with APUs. That's just in gaming. When you include other applications it can make a surprisingly decent impact on overall performance.

I wasn't assuming anything, that's why I asked "What do you mean?". I hope you can understand how saying "DDR[x] 2400, and faster than any kind of DDR[x] 1600" can be confusing considering it's not true. Now I understand what you meant though.
