1.8.1 Sample calculation: DIMM memory capacity
Suppose you install a 512 MB DIMM into your PCA-6186's socket 1 and
a 512 MB DIMM into sockets 2. Your total system memory is 1 GB, cal-
culated as follows:
Total memory 1 GB]
1.9 DDR memory speed combinations
The following table provides information on the 400/533MHz front side
bus speed and the DDR200/266/333 memory speed combinations that
can be used with the 82845GV. This is the B1-stepping 82845GV.
Note :
Reference the "Intel 845G/845GL/845GV Chipset Specification
Update", document number 29865-706, for the following changes :
(1) The 82845GV adds unregistered and non-ECC DDR333 capability
(2) The use of unregistered and non-ECC DDR333 is limited to those
82845GV platforms that have a 533MHz front side bus speed.
DDR333 memory capability cannot be used in 82845GV platform that
have a 400MHz front side bus speed.
1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket
are in the "open" position. i.e. The handles lean outward. Slowly slide the
DIMM module along the plastic guides on both ends of the socket. Then
press the DIMM module right down into the socket, until you hear a
click. This is when the two handles have automatically locked the
