Targeted DDR2 upgrade kit
This 4 GB kit contains two 2 GB DDR2-800 DIMMs built for Intel DG31GL, DG41MJ, DG41RQ and DG41TY motherboards. The modules run at 1.8 V with CL6 6-6-6 timings and are unbuffered non-ECC. They install directly into the board's 240-pin slots without configuration changes. Buyers restoring or maintaining these specific legacy platforms receive a matched pair guaranteed compatible by the manufacturer.
Matched pair convenience
The two sticks are tested together so they operate in dual-channel mode on the supported boards. No extra cables, brackets or software are included; the kit is purely the memory modules themselves. System integrators avoid the uncertainty of mixing loose DIMMs of unknown origin or timing. The only change versus single modules is the factory-matched pairing that the board's chipset can use for dual-channel bandwidth.
4 GB total capacity
Four gigabytes fills half the board's four DIMM slots and reaches the 8 GB maximum the chipset can address. Everyday office applications, web browsing and light multitasking run comfortably within this limit. Memory-intensive workloads such as virtualisation, modern gaming or large media editing will exhaust the available space and cannot be expanded beyond the platform's 8 GB ceiling. Builders needing more than 8 GB must choose a different platform.

Questions about this item
Will the 240-pin DDR2 DIMMs need any firmware updates or re-seating over time?
No firmware is involved; the modules are unbuffered non-ECC DDR2-800 CL6 parts that simply plug into the 240-pin slots. If a stick ever fails, replace the pair to keep the dual-channel kit matched.
What stops the kit from running faster than 800 MHz on the DG41TY motherboard?
The motherboard chipset and its memory controller are rated for DDR2-800 maximum, so the 6400 MT/s modules already hit the platform ceiling.
How much heat and noise do the 1.8 V sticks add when the system runs all day?
The modules have no heat spreader and draw standard 1.8 V DDR2 power, so they add only a small amount of warmth and no audible noise; case airflow handles the rest.
