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.

Otázky k tomuto produktu
What DDR2 standard and speed does this 240-pin kit run at?
The modules are rated PC2-6400 at 800 MHz with CL6 timing and operate at 1.8 V.
Will the two 2 GB sticks fit the four DIMM slots in my Precision 390?
Yes, each stick is a standard 240-pin unbuffered DIMM and the system has four slots supporting up to 8 GB total.
What is the correct way to seat the pair so the board recognises the full 4 GB?
Insert both modules firmly until the retention clips click, then power on and verify 4 GB in BIOS; the common mistake is leaving one clip unlatched.
