  • 5 V standard voltage and 240-pin DIMM form factor

64GB DDR3 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR3 1066 registered DIMMs built for servers and workstations that require ECC memory. Each module runs at 1.5V with a 4Rx4 quad-rank organisation and a 240-pin interface. The registered buffer helps the memory controller manage heavy loads in multi-socket systems.

Suits DDR3 RDIMM platforms only

These modules work exclusively in servers and workstations that support DDR3 registered ECC memory with 4Rx4 ranking. They will not fit desktop or laptop computers that use unbuffered non-ECC DIMMs. Buyers who need memory for a consumer PC should look elsewhere.

4Rx4 quad-rank organisation

The 4Rx4 configuration places four ranks of x4 chips on each DIMM, which increases density but also places a heavier load on the memory controller. Verify that your system's memory controller and BIOS support 4Rx4 registered modules before purchase.

Questions sur cet article

How do I install the 4Rx4 DDR3 RDIMMs in the correct quad-channel slots?

Populate all four 240-pin slots following the motherboard manual's quad-channel sequence; the common mistake is mixing registered DIMMs with unbuffered modules or placing them in the wrong channel order.

When will the 1.5V ECC modules need replacement under normal server loads?

DDR3 RDIMMs have no scheduled replacement interval; they run until a correctable ECC error rate climbs or a module fails POST, which typically takes many years at 1066 MHz.

What thermal or signal limit appears first during sustained 1066 MHz operation?

The 1.5V JEDEC voltage ceiling is reached before thermal throttling; sustained full-load bandwidth is capped by the PC3-8500 data rate and quad-rank electrical loading.
