memory upgrade not recognized
Posted on 1999-01-28
I have a P5F85 motherboard designed around the 82430TX chipset. It has (2) 168 pin DIMM slots and (2) 72 pin SIMM slots for memory. I have 32MB SDRAM installed in each DIMM
slot (64MB total). They are 16M-bit based with the following number written on each of the 16 chips per module: 81116822C-100LLFN 9746 M17. I wanted to upgrade my memory by adding (2) 32MB simms into the simm slots. I needed to know if this motherboard could handle this and if any settings in the bios or jumpers needed to be changed, so I emailed the motherboard maker (to make sure) and they assured me that this could be done, as long as the
dimms were not 64M-bit and that both simm slots were filled with 32MB or less simms (same type, speed, size). The bios would recognize the upgrade automatically. The manual said it could take FP/EDO type, so I went and bought (2) simms to fill the slots. They are 72 pin, EDO, 8x32, 60ns,32MB. When I installed them, the computer only recognizes 64 MB.
Installation and memory modules are OK. Any suggestions?
