8GB DDR3 1600MHz Desktop Module

This 8GB DDR3 DIMM runs at 1600MHz with a CAS latency of CL11 and standard 1.5V operation. It uses a 240-pin unbuffered non-ECC design built on Samsung chipset. The module serves as a direct compatible replacement for the Samsung M378B1G73AH0-CK0 part number. It targets desktop owners who need a straightforward memory upgrade without ECC or registered features.

Capacity and Headroom for Everyday Loads

The single 8GB stick adds substantial headroom for web browsing, office suites and light creative work on DDR3 platforms. Dual-rank 2Rx8 organisation helps memory controller efficiency at this density. Systems limited to two DIMM slots gain maximum capacity from one module. Workloads that exceed 8GB total system memory will page to storage, reducing responsiveness.

Tested Reliability and Lifetime Support

Every module undergoes quality assurance testing before shipping to verify dependable operation at rated specifications. A lifetime warranty backs the hardware against defects for the usable life of the product. United States based technical support is available before, during and after purchase for installation or compatibility questions. No heat spreader is included, keeping the module low-profile for tight chassis clearances.

Questions about this item

Will the 1.5V DDR3 1600MHz module run stably alongside older 1.5V DDR3 1600MHz sticks?

Both modules share the same 1.5V voltage and 1600MHz speed rating, so the system will default to the slowest common timing.

How can I confirm the CL11 8GB stick is operating at PC3-12800 after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 1600MHz frequency and CL11 latency.

Does the M378B1G73AH0-CK0 box include a 240-pin DIMM only, or are extra accessories supplied?

The package contains the single 8GB 240-pin unbuffered DIMM; no heat spreader, cables or tools are included.
