64GB DDR4-2666 ECC kit for Dell PowerEdge
This 64GB kit contains four 16GB DDR4-2666 ECC unregistered DIMMs built for Dell PowerEdge R240 and R340 servers. Each module runs at 1.2V with CL19 timing and a 2Rx8 organisation. The 288-pin design matches the memory slots in those systems.
Sustained load behaviour with ECC and CL19
Error-correcting code detects and corrects single-bit errors during continuous operation, protecting data integrity in long-running workloads. The CL19 latency and 2666 MT/s data rate deliver steady throughput for multi-threaded server tasks. Unregistered signalling keeps the command path direct for consistent response under load.
Platform limits: four slots and 64GB maximum
The PowerEdge R240 and R340 each provide four DIMM sockets and a 64GB memory ceiling, so this kit fills every slot and reaches the platform limit. Faster modules will automatically clock down to 2666 MT/s to match the processor's memory controller. No additional capacity can be added once all four sockets are populated.

שאלות על הפריט הזה
How much heat and power does this 1.2 V DDR4 2666 ECC kit draw when the server runs continuously?
At 1.2 V the four unregistered DIMMs run at standard DDR4 voltage, so heat output and power draw stay at typical DDR4-2666 levels for 24/7 operation.
What must my Dell PowerEdge already have for these four 16 GB modules to work?
The R240 or R340 needs four free 288-pin DDR4 slots and a processor that supports ECC unregistered memory up to 64 GB total.
Will the CL19 2666 MHz sticks run at full speed beside older DDR4 modules I keep in the same server?
All installed DDR4 will clock to the lowest common speed; if older modules are slower than 2666 MHz the new kit will downclock to match.
