Targeted Server Upgrade

This 4GB kit contains two 2GB DDR2 modules built for the Dell PowerEdge R200. ECC protection and unregistered operation match the server’s memory architecture exactly. The 240-pin form factor installs directly into the four available slots without adapters or configuration changes. System administrators maintaining legacy infrastructure receive guaranteed compatibility from a specialist memory brand.

Thermals and Power

Operating at the standard 1.8V DDR2 voltage, the modules draw minimal power inside the chassis. No heat spreader is fitted, so airflow from the server’s existing fans passes over the chips unimpeded. CL6 timings at 800MHz keep electrical load steady during typical workloads. The design adds no measurable acoustic contribution to the rack environment.

Build and Connectivity

Major-brand chips are assembled on a standard 240-pin PCB with 2Rx8 organisation. Gold edge contacts resist oxidation during long service intervals. The two-stick package lets you populate a pair of slots for dual-channel bandwidth or distribute modules across all four sockets. Physical dimensions follow the JEDEC DIMM outline, so the latching levers engage normally on the R200 motherboard.

Questions about this item

How do I install the 240-pin DDR2 DIMMs into the Dell PowerEdge R200 and what step is often missed?

Power off the server, open the chassis, align each 240-pin module with the slot notch, press firmly until the retention clips click, then verify in BIOS that all 4GB are detected at 800 MHz.

What maintenance or replacement will the ECC non-registered memory need over time?

The modules have no heat spreader and run at 1.8V; keep server fans and air filters clean so temperatures stay within spec, and replace any stick that begins reporting correctable ECC errors.

What limit appears first when the memory runs under sustained load in the R200?

The DDR2-800 CL6 timing and 1.8V voltage set the bandwidth ceiling; sustained workloads will saturate the 6400 MT/s data rate before thermal throttling becomes a factor.
