RAM upgrade - 128Mb recognised as 64Mb

  18wheeler 09:56 21 Jan 05

Running a Celeron 433MHz on a P6BXT-A+ mainboard (do I sound like I know what I'm talking about?) I wanted to add some extra RAM. The mainboard users manual says I must use 168pin 3.3V non-buffered DIMM, either standard or synchronous and running at 100MHz. I bought two DIMM 128Mb 168pin units (synchronous). When installed, they get recognised only as 64Mb each instead of 128Mb. I've tried various combinations in the three DIMM slots.

Can anyone suggest what's the problem? And how to fix it?

If you have only one in, what is it recognised as? 64 or 128? If 64, then either a) it is 64 or b), the slot is only capable of recognising 64 maximum.

What did you have in before you brought the new ram?

Either the new memory is faulty (unlikely to have two sticks fail)


your old motherboard only recognises the chips on one side of the memory stick(commom)
