How to change RAM in BIOS?

HOW to get more ram seen by the BIOS

• I bought an IBM 300GL and the system only sees 64 out of 256 megs of ram. The BIOS will not let me change this. What can I do to get my Ram recognized?

• Answer:

  Hi andy182, Assuming you are using properly working supported RAM, your BIOS will automatically recognize your memory. It sounds to me like either your RAM is defective or the wrong type. For the IBM 300GL, you must use 3.3V 100MHz unbuffered SDRAM DIMMS. You must fill the slots in order, meaning DIMM slot 0 must be filled before DIMM slot 1 (there are only 2 slots). Be sure to use RAM that is NOT high density. Some older computers cannot properly address this type of memory. My recommendations: 1) Find out what RAM you purchased. If it's not 3.3V 100MHz unbuffered SDRAM DIMMS, return it and buy that type. Be sure not to purchase HIGH DENSITY RAM as many older computers cannot properly address this. I suggest you check <a href="http://www.pricewatch.com">Pricewatch.com</A> to find lots of options for buying RAM. <a href="http://www.kingston.com">Kingston</A> also sells RAM for this machine at <a href="http://www.ec.kingston.com/ecom/configurator/models.asp?System=&Distributor=0&OriginalSysPN=&Manufacturer=IBM&WildCard=300gl">http://www.ec.kingston.com/ecom/configurator/models.asp?System=&Distributor=0&OriginalSysPN=&Manufacturer=IBM&WildCard=300gl</A> 2) If you have the correct type of RAM, properly installed, then return it. It is most likely defective. Note that the IBM 300GL can take a maximum of 512MB RAM and the largest single stick you can use is 256MB.
