Description
XMM3 socket, Channel A (populate first)
XMM4 socket, Channel B
NOTE: A DIMM must occupy the XMM1 socket.
For proper system operation, the DDR3-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support 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
