4GB DDR3 1333MHz Desktop Module

This Timetec module is a 4GB DDR3 SDRAM stick built to the PC3-10600 standard at 1333MHz with CL9 latency. It uses a 240-pin UDIMM form factor and operates at either 1.5V or 1.35V. The dual-rank design uses 256x8 chips for broad compatibility with older desktop platforms.

For Dell Optiplex 780 Upgrades

This memory suits owners of a Dell Optiplex 780 DT, MT or SFF who need a single 4GB low-density module. It will not fit laptops or any system that requires SODIMM modules. Builders needing ECC registered memory or capacities above 4GB per slot should look elsewhere.

Dual Voltage 1.35V / 1.5V Operation

The key specification is the dual-voltage rating of 1.35V and 1.5V, allowing the module to run in both DDR3 and DDR3L slots. This flexibility decides whether the part works in a given board. The module also meets JEDEC standards for 1333MHz at CL9.

Questions about this item

How do I install this 240-pin DDR3 module in a Dell Optiplex 780 and what step is often missed?

Power off the PC, open the case, align the notch on the 240-pin edge connector with the DIMM slot key, press firmly until both retention clips click, then verify in BIOS that the module runs at 1333 MHz and 1.35 V or 1.5 V.

What maintenance or replacement will this 4 GB dual-rank kit need over its lifetime?

No scheduled maintenance is required; keep dust off the gold contacts and ensure the CPU cooler maintains safe case temperatures, as the module itself has no moving parts or wear items.

What limit appears first when this CL9 1333 MHz memory runs under sustained heavy load?

The 1333 MT/s data rate and CL9 latency ceiling will bottleneck throughput before the 1.35 V / 1.5 V dual-voltage headroom or thermal envelope becomes a factor.
