Bank Interleaving Requirements

[FallOutBoyTonto]

What are the requirements of bank interleaving? Although I've read <A HREF="http://www.rojakpot.com/showBOG.aspx?bogno=116" target="_new"> this</A> article, I still don't understand it completely and I've got a few questions.

- What size of RAM is needed for 4-bank interleaving?
- If I'm running Dual DDR, can I get 8-bank interleaving?
- Do all large DIMMs have the ability to use 4-bank interleave?
- Are there any other articles that will help me understand bank interleaving?

Thanks in advance for the help you'll give.

"- What size of RAM is needed for 4-bank interleaving?"

"- Do all large DIMMs have the ability to use 4-bank interleave?"


For 4-Bank interleaving you will need modules with densities higher than 64 Mbit. If they are 32 Mbit then they will allow for 2-Bank and 16 MBit will only allow for single-bank. The amount of interleaving is 100% dependent on memory densities. (Unless you have an older board that was designed around interleaving. I have one in a 2-Bank hardwired setup.)



"- If I'm running Dual DDR, can I get 8-bank interleaving?"

That is a good question. It will depend on the chipset and the MCH. The nForce2 board should be able to do "8-Bank" in essence. It will be doing 2 4-Bank setups. It uses two MCHs and thus they are independent of each other. (I could be wrong but I have never looked at the nForce2 MCHs that way before.)

I've heard on the <A HREF="http://www.guru3d.com/forum/showthread.php?threadid=54674&goto=newpost" target="_new"> Guru3D Forum</A> that only VIA chipsets are able to use bank interleaving. Is this true? Can the nForce2 also use that feature?

You didn't read him correctly...

"If you do not own a VIA based board <b><font color=red>or if it's not in your BIOS</font color=red></b> then you don't have the option and I wouldn't worry about it any further than that."

If you do not have interleaving as an option in you BIOS (Most current boards) then you cannot use Bank Interleaving.
