Ddr Types And Ecc

I just looked up all the Types of DIMMs and I am getting a little mixed up.

DDR Pin Count is 184 and it is 64 Bits.
DDR2. Pin Count is 240 and it is 64 Bits.
DDR3. Pin Count is 240 and it is 64 Bits.
DDR4. Pin Count is 288 and is 64 Bits.

Now first tell me if I have this Right?

Now if any of the DIMMs have ECC they will be 72 Bits.
But will the Pin Count be the same?

Take DDR2. Pin Count for 64 Bit is 240.
But if it is ECC it will be 72 Bits so does the Pin Count go up?

 

What are you trying to do.

Are you trying to upgrade.???

If so we need to know what kinda mother board you have and we can redirect you to the right RAM needed.

Download speccy Speccy 1.32.740 And copy and past the info for us please.

 

No I just wanted to know if I have these Pin Countys Right?
DDR Pin Count is 184 and it is 64 Bits.
DDR2. Pin Count is 240 and it is 64 Bits.
DDR3. Pin Count is 240 and it is 64 Bits.
DDR4. Pin Count is 288 and is 64 Bits.
