Can you/should you have 4-way interleaving enabled w/one-sided 128mb sticks of RAM?

I just had an Epiphany (I think). Having booting probs w/my GFs PC. Get those "config/system32" errors when W2K tries to boot. (Bios boots fine) The mobo has two, 128mb sticks of memory.

Someone told me this is possibly a memory error and to try booting w/just one stick (both sticks are Crucial PC133). I don't have it in front of me to look at, but isn't a 128mb stick one-sided? I.E. chips on one side of the PCB only?

If so, I shouldn't have 4-way interleaving enabled, should I?

It depends on the density of the chips. If you have 128Mbit chips, then you're going to have 8 chips on one side only. If you have 64MBit chips, you'll have 16 chips on both sides. Mine happens to be a low-density module.

So, if I have 128-bit, then 4-way is OK. If 64-bit, 4-way is not? Is this correct?

Folks, that "bank interleaving" uses the SDRAM devices' _chip_internal_ banks. Now since SDRAM chips from 64-MBit technology
upward are always 4-bank, you can have 4-bank interleave with any DIMM that has at least 64 MBytes per side (!), in other
words, from 64-MByte single-sided 8-chip DIMM upward.
