Essa board deverá aceitar 1333 e 1066mhz. Se não me engano é algo do tipo hp/compaq 8000
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
● 1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
● support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz (9-9-9
timing)
● contain the mandatory JEDEC SPD information
In addition, the computer supports:
● 512-*****, 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.
