HP (Hewlett-Packard) AT496AV-1 Personal Computer User Manual


 
Installing Additional Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 16-GB of memory.
DDR3-SDRAM DIMMs
For proper system operation, the DDR3-SDRAM DIMMs must be:
industry-standard 240-pin
unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz-
compliant
NOTE: 1333 MHz DIMMS may only run at a speed of 1066 MHz, depending on the processor.
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
support CAS latency 8 DDR3 1066 MHz (8-8-8 timing) and CAS latency 9 DDR3 1333 MHz (9-9-9
timing)
contain the mandatory JEDEC SPD information
In addition, the computer supports:
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
single-sided and double-sided DIMMs
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported DIMMs.
