Dell-compatible DDR2 kit
This 16GB kit contains two 8GB modules built for Dell workstations and servers that require fully buffered DDR2 memory. Each stick is a 240-pin DIMM rated at DDR2 667 (PC2 5300) with CL5 latency and 1.80V operation. The ECC and fully buffered design targets data-integrity workloads on supported Dell platforms.
Sustained-load behaviour
Fully buffered architecture places an advanced memory buffer on every module, reducing electrical load on the motherboard when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation, helping prevent silent data corruption in long-running tasks. The registered command and address signals further stabilise timing under heavy, sustained memory traffic.
DDR2 667 interface limits
The DDR2 667 interface caps peak bandwidth at the PC2 5300 rate, so throughput cannot exceed this ceiling regardless of workload. Fully buffered modules are mechanically keyed differently from standard unbuffered DDR2 DIMMs and will not fit or function in desktop boards that lack the required chipset support. Systems must explicitly support FB-DIMM technology for the kit to operate.

Questions about this item
Does the 16GB CL5 DDR2 667 FB-DIMM kit generate noticeable heat or noise when running continuously?
The modules operate at 1.80V with CL5 latency and have no moving parts, so they produce minimal heat and run silently during all-day workloads.
What must my Dell system already provide for these 240-pin DDR2 667 FB-DIMMs to function?
Your Dell workstation needs a motherboard with 240-pin DDR2 slots that accept fully buffered ECC memory and a chipset supporting PC2 5300 speed.
Will the 16GB CL5 DDR2 667 FB-DIMM pair work alongside older Dell-approved modules such as part numbers A1787400 or A2257216?
These modules share the same DDR2 667 CL5 ECC fully buffered specification as the listed Dell part numbers, allowing mixed-capacity configurations in supported Dell systems.
