I've just put 64Mb of sdram into my W98/AMD K6 PC in place of 64Mb EDO simms - but MSD and other measurers, inc. the startup display, show only around 16Mb !!!   Any ideas, help.   Dan.

If the bios startup mem count goes to 16Mb, my guess is it is a 16Mb DIMM or it is faulty.

You might check the AMD site and verify that your motherboard/BIOS can recognize SDRAM. My P6-200 can only use EDO or FPM....

As there are two sdram sockets I assumed that it was reasonable to insert sdram into them.  I also assume that unlike Edo ram, I can insert one only sdram module, and they don't need to be in pairs.  Also the sdram is 100Mhz type.     Dan

Try to enter and exit and save the bios settings, it should update automatically.

I now understand that 100Mhz sdram can not be used in a PC with a 66 Mhz bus, it needs a 440BX chipset.
