Signature Line DDR3 4GB 1600MHz CL11

Patriot Signature Line DDR3 4GB desktop memory module runs at 1600MHz PC3-12800 with CL11 latency. It is an unbuffered non-ECC UDIMM built for standard 240-pin DDR3 slots. The single-rank 4GB stick operates at 1.50V without a heat spreader.

System upgrades and legacy repairs

This module suits owners of DDR3 desktops needing a direct 4GB replacement or a simple capacity increase. It does not suit systems that require ECC or registered memory. It does not suit motherboards limited to lower DDR3 speeds or different pin counts. Builders wanting capacities above 4GB per slot should look at larger modules.

DDR3 1600MHz PC3-12800 speed rating

The decisive specification is the DDR3 1600MHz PC3-12800 rating with CL11 timing at 1.50V. The motherboard must support this exact DDR3 speed and voltage for correct operation. Verify the platform accepts unbuffered non-ECC UDIMMs before purchase.

Questions about this item

Will the 240-pin DDR3 module fit a standard desktop DIMM slot?

Yes, the 240-pin UDIMM is built for standard desktop DDR3 slots and the 118 mm PCB height matches the usual desktop form factor.

What is the correct way to seat the module and which step is often missed?

Align the notch with the slot key, press down evenly until both side clips click shut; the step often missed is verifying both clips have fully engaged.

Does the 1.5 V DDR3 module need any firmware updates or component replacements over time?

No firmware or replacement parts are required; the module runs at 1.5 V with auto and self-refresh and a 7.8 µs refresh interval for the life of the system.
