My mobo has (1)DIMM and (4)SIMM slots. Can I use both?

[jyp]

I have PT-2006 mobo, I don't know what brand that is, it doesn't say on the board except 'PT-2006'. It's an old 150Mhz machine w/ some jumper change to 166Mhz and I currently use 4 Simm slots of memory but I see there is 1 DIMM slot. I plugged in 32M Dimm but it won't boot up. It doesn't seem to recognize it is there. I looked in the BIOS for any settings that was for DIMM but I didn't see anything relevent.
It will only boot up with SIMM cards in it. When I put both DIMM and SIMM it doesn't recognize DIMM and boots up with only SIMM.

How can I use DIMM? If it's there obviously it is meant to be used right?

Help!

FIC makes a PT-2006. You can find the manual for it here: ftp://ftp.fica.com/manuals/motherboards/Pt-2006/

Hopefully it should tell you if you can use both at the same time or not.

The answer to your question is no. DIMMs and SIMMS run at different voltages. Even if the board would allow it, the dimms would be run at 5volt instead of 3.3v. Overtime they would die out.

5v dimms used to be available, havn't seen any in a while. Some mobos did allow the use of both but the dimms had to be 5v if I recall.
