Solution:

We have test 1Mx32-60EDO DRAM module OKI M5118165D EDO RAM with some of our CPU boards. The EDO RAM support for ALI M6117 chipset of PCA-6135 is critical. Although the newest c version of M6117C ( rev. B1 of PCA-6135) can support some of "EDO" DRAM such as NEC 46481660-60. However, it is not compatible with your M5118165D 1M x32 SIMM. I have tested this DRAM with some of our CPU card. The result comes out to be: ALI M1219 No ALI M6117 No ALI M1489/1487 OK VIA 82C496 OK In general, the newer chipset can support this EDO RAM. This is the hardware limitation. If customer must use this module We will suggest him use PCA-6145. For the other EDO RAM for PCA-6135, we suggest you test it befor buying it.
