Computer Memory Solutions 4GB (2x2GB) DDR2 800MHz PC2-6400 CL6 1.8V Non-ECC DIMM Dell Precision 390

Dell Precision 390 upgrade kit

This 4 GB kit contains two 2 GB DDR2 modules rated at 800 MHz with CL6 timings and 1.8 V operation. The unbuffered, non-ECC DIMMs use a 240-pin layout and are built with major-brand chipsets. Computer Memory Solutions validates the kit specifically for the Dell Precision Workstation 390.

Owners of a Precision 390 needing a matched pair

The kit suits users restoring or expanding a Precision 390 that accepts DDR2 memory. Systems that require ECC, registered modules, a different pin count, or a later memory generation will not accept these sticks. Buyers with other Dell workstations should verify their exact model before purchasing.

DDR2 800 MHz CL6 specification

The modules run at PC2-6400 speed with 6-6-6 timing at 1.8 V. This electrical and timing profile is the single factor that determines whether the kit will post and run stably in the Precision 390. Any deviation in speed, voltage or latency means the memory is not the correct part for this workstation.
