Compaq Presario Memory Upgrade not registering

[samajm]

I am refurbing a Compaq Presario 2244ES for a friend. It has 16MB of Ram onboard and had a 16mb stick in it. I have read that it allows up to 64 mb total, even if you use a larger amount. I put in what I was told is a 64mb stick and it's still just showing as 32mb total. Is there a setting I need to change. Not seeing any options in the BIOS. Shouldn't it just recognize it automatically?
Thank you in advance for any help you can provide.

max ram specified for that system was 48MB (16MB on board + 32MB max in upgrade slot) of PC-66 RAM

I suspect that 64MB module is not fully addressable by the hardware in that PC and that's why you're only seeing a partial increase.

well fudge! if i get just a 32mb stick should it pick it up automatically then?
thank you for your help. any kind of a Bios update that would help?

yup needed just a straight 32mb stick. My cousin will be cooking with a FULL 48mb now. Thanks for the help.
