Memory
269
At start-up, the BIOS identifies the components that require address space. The BIOS dynamically
calculates the amount of reserved address space required. The BIOS then subtracts the reserved
address space from 4 GB to determine the amount of usable space.
•
If the total installed computer memory is less than the usable space, all installed computer
memory is available for use only by the operating system.
•
If the total installed computer memory is equal to or greater than the usable address space, a
small portion of installed memory is available for use by the operating system.
Removing Memory
CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide
.
NOTICE:
If you remove your original memory modules from the computer during a memory upgrade,
keep them separate from any new modules that you may have, even if you purchased the new modules
from Dell. If possible,
do not
pair an original memory module with a new memory module. Otherwise,
your computer may not start properly. You should install your original memory modules in pairs either
in connectors DIMM1 and DIMM2 or connectors DIMM3 and DIMM4.
NOTICE:
Removing memory modules from DIMM2 and DIMM4 on the desktop computer requires
you to remove the optical drive (see "
Drives
"). Failure to do so may cause damage to the memory
module and the DIMM socket.
NOTE:
Memory purchased from Dell is covered under your computer warranty.
