I decided to bump this because of the title-

I have to admit my ignorance here and ask for help. If you may have covered this topic once before, my searches are turning up a sea it's probably swimming in- please drop a link or few. I'm in that frustrating spot where everything I've seen assumes I know something I don't

1. Help me understand, please. What does TCCD mean technically? (TCC5 too if it will fit)

I tried looking it up on Google- is TCCD the CAS-to-CAS Delay Time? I assume your useage must be more specific because I thought all DDR memory had this.

2. Hopefully the answer to 1. will help say why it is so special.

3. Is Samsung the only maker?

4. Many sites are NOT helpful in specifying this or the chip makers in their memory. What can you tell me that would help me identify it when I shop somewhere that does not? Is there a master key, numbering, or table I can use?

5. Are there any 1GB sticks (I'm thinking 2 x 1GB) of this? Newegg only shows 2 x 512MB for anything with TCCD in it.

I'm afraid I'm not up on this and it is like the last step in scoping out a new system.

Thank you!
