I have a NEC Model Ready 9670 with 200MHZ Pentium; 16 MB EDO RAM. I ordered an additional 16MB of memory from PNY Technologies. When I installed the memory Windows 95 showed 24 MB installed instead of 32 MB. I removed original memory from banks 0 & 1 and put new memory in their place. 16 MB showed up so I presume the new memory is good. I put the old memory in banks 2 & 3 and only 16 MB showed up. I put old memory back into its original place and put the new memory in banks 2 & 3 again and it showed 24 MB. PNY technicians said it was the mother board. I took it to a factory authorized NEC technician who installed "his" additional memory and it showed 32 MB. He said the new memory I got may be incompatible with the old. PNY Technician disputed this and said it is a problem with the computer. Now I am caught in a loop between 2 technicians and need some help. The computer is still under warranty but I incurred a labor charge because nothing was wrong (supposedly) with the computer. PNY says nothing is wrong with the memory although they have agreed to give me a replacement. The memory original to the computer has 8 chips on each side of the simm with the following written on each chip: HY514404A LJ-60F 50Z 97288 Malaysia On the other side the numbers on the chips are slightly different: HY514404A LJ-60F 08Z 9726B Malaysia The PNY chips look different. There are only 2 chips on each side of the simm: Siemens HYB5118165BSJ-60 Germany G 9736 Any ideas to help would be most appreicated.
