Targeted Dell Vostro Upgrade

This 4GB DDR3 1600 module is built for Dell Vostro 470, 3800 and 3900 desktops. It installs as a single 240-pin UDIMM to add capacity without configuration changes. The JEDEC-standard part is validated for those specific models.

Steady CL11 Operation

Rated at PC3-12800 with CL11 latency, the module maintains its 1600MHz data rate during extended workloads. Unbuffered non-ECC architecture delivers consistent throughput for everyday multitasking and larger file handling. The 1.5V supply keeps power draw predictable under load.

Plain 240-Pin DIMM Build

No heat spreader means the low-profile PCB fits tight Dell chassis without clearance issues. Gold-edge contacts on the 240-pin connector ensure reliable seating in standard UDIMM slots. RoHS-compliant assembly and OWC in-house testing support long-term service in the target workstations.

Questions about this item

Does the 1.5 V DDR3 1600 module run hot or draw extra power during all-day use?

Standard 1.5 V JEDEC DDR3 operates within normal thermal limits and does not need active cooling.

What must the Dell Vostro 470 already have so this 240-pin UDIMM fits and works?

A free 240-pin DDR3 UDIMM slot and a BIOS that accepts 4 GB non-ECC PC3-12800 modules.

Will this CL11 1Rx8 stick work beside the original memory in a Vostro 3800 or 3900?

Yes, it is tested for those models; match speed and voltage for best stability.
