I stuck 2x32Mb FPM and 2x16Mb EDO sticks in my NeXTstation turbo and it reads it as 80mb and boots up... :] Is it supposed to even boot with mixed types like that? Would the fact that two are FPM and two are EDO make it read the ram weird and only give me 80mb instead of 96?
it also seems to be running slower than normal... heh.
*edit*
oh, to get 80mb would be 2x8 + 2x32.. the edo is double sided, seems mixing it with FPM is causing it to only read one bank, maybe?
total coincidence, noticed something similar too.
last week i happen to put 2 32MB edo sticks from an old P200 with 2 original 8mb sticks in my Turbo slab which has 4 banks and it didn't pick up the second bank of the 32 MB stick. But i was happy that it worked.
I didn't notice any speed differences but during boot the testing section was longer probably due to the memory testing having more to test.

Yeah, it *should* work. Al that happens is you get the lowest common denominator. The worst speed and worst operation mode, in other words.
The dual sided issue - that might just be the mother boards. For example, my old Mac G3 (beige) can only read one side of a lot or DIMMS. This is down to the memory hardware, not the sticks of memory.
ll, I didn't think about this till a bit ago.. The 2x16 EDO sticks worked fine *as* 16mb when I had 4x16 of them in the slab. I took out two and put the 32 FPM sticks in and the EDO suddenly dropped to being read as 8mb.. weird.
should of mentioned the I used was single sided while the orignal Next Memory was double sided.
I alsos experimented with the banks, i switched the two edo pairs with the 2 Next sticks and it did the same thing too.
Note, i thought since it wasn't picking up the second bank to leave it empty to be able to use the stick elsewhere but then it didn't pick up either stick in that case when i rebooted (which i expected not to work).
Helf, maybe the slowness is the speed of the memory itself?
one more thing,
typing "m" during the Rom monitor shows you exactly what is being picked up.
