ok, maybe a stupid question, but since I don't know the answer (and can't seem to find it on the web anywhere after searching), I'm gonna ask: I'm fixing up my dad's pc, and I just got him another 128MB DIMM for in his PC. He's already got 1 64MB DIMM, and one 128MB DIMM, so now he'll have 320MB total. My question is: which is the best/optimal (performance-wise) arrangement to place these DIMMs on the motherboard? Should the 64MB DIMM go in the first bank? Or should it be last?

(oh, it's all PC133 CAS3, so no big deal there, and the DIMM I just got for him is from Crucial, while the previous two DIMMs are from who knows where.)

thanks for any imput.

ok, well, i may have answered my own question. I just found this on Crucial's site:

>>>>
Description: Does it matter which slot I plug my new module in?

Solution:

In general, you will get the best performance if you put the largest module (in megabytes) in the lowest-numbered slot. For example, if your computer comes with 32MB of removable memory and you want to add 128MB, it would be best to put the 128MB module into slot 0 and the 32MB module into slot 1
<<<<

do you agree with this?

It order in which the DIMM's are situated won't impact performance much irregardless of how you have them configured, but for reliability sake one should almost always put the largest DIMM into slot 1, and work your way from there to the smallest DIMM in the final slot.
