Server memory upgrade for Dell systems

This 8GB DDR3 1066MHz ECC RDIMM module replaces Dell part numbers A2626061, A2626071, A2626092, A3116521, A3721494, A3721500, A3721505, A3858988, A4051418, A7052229 and SNPK075PC/8G. It targets administrators maintaining compatible PowerEdge or Precision servers that require registered error-correcting memory. The single 240-pin DIMM adds capacity to supported multi-socket platforms.

DDR3 1066MHz bandwidth and registered buffering

The PC3-8500 interface delivers 1066 MT/s throughput with CL7 latency at 1.50V. Registered buffering places a register between the DRAM and the memory controller, reducing electrical load so larger populations of modules can operate stably. This design limits maximum speed to the DDR3 1066 standard; systems needing higher frequencies or unbuffered DIMMs cannot use this module.

Major-brand chips on a 240-pin registered DIMM

The 4Rx8 organisation uses major-brand chips mounted on a standard-height 240-pin PCB. The registered design adds a slight height increase over unbuffered DIMMs, so adjacent-slot clearance should be verified in dense blade or 1U chassis. Gold-edge contacts meet DDR3 JEDEC specifications for reliable insertion cycles during maintenance windows.

Questions about this item

Should I choose the 8 GB 4Rx8 module or a different rank for my Dell server?

This module is an 8 GB DDR3 1066 MHz ECC RDIMM with a 4Rx8 organisation. Select it when your system requires a single registered 240-pin DIMM at 1.50 V that matches Dell part numbers such as A4051418 or A3721494.

What does the 1066 MHz speed deliver in a real server?

The module runs at 1066 MT/s with CL7 latency at standard 1.50 V DDR3 voltage, providing the rated PC3-8500 bandwidth for compatible Dell PowerEdge and Precision platforms.

How does the DDR3 RDIMM interface limit performance?

The 240-pin registered DDR3 interface operates at 1.50 V and caps the data rate at 1066 MT/s, so the module cannot exceed the PC3-8500 specification even if the memory controller supports higher speeds.
