Server Memory Upgrade

This 8GB DDR3 module runs at 1066MHz (PC3-8500) with CL3 latency and 1.50V operation. It is built as an ECC registered DIMM using a 4Rx8 organisation for error-correcting server and workstation platforms. The 240-pin form factor fits standard DDR3 DIMM slots in compatible systems.

Elpida Replacement Compatibility

The module is specified as a compatible replacement for the Elpida EBJ82RF8BCFA-AE-F part number. Builders can use it to match existing memory configurations that require this exact Elpida reference. Verification of the host system's supported memory specifications remains essential before installation.

DDR3 Interface Limits

DDR3 technology tops out at lower transfer rates and higher voltages than later generations. Registered DIMMs add a clock cycle of latency and require chipset support for buffered operation. The 4Rx8 density may exceed the rank-per-channel limits of some older memory controllers. 8GB capacity per module restricts total system memory on platforms with few DIMM slots.

Questions about this item

How often will the 4Rx8 registered ECC chips need replacement in a 24/7 server?

DDR3 ECC RDIMM modules have no scheduled replacement interval; they run until a correctable error rate rises or a hard failure occurs, which typically takes many years in normal server workloads.

What is the first limit reached when this PC3-8500 module runs at full 1066 MHz load continuously?

The 1.50 V DDR3 standard voltage and 4Rx8 organisation set the thermal and signal-integrity ceiling; sustained maximum bandwidth will hit the JEDEC-defined timing and temperature envelope before any other constraint.

How much heat and power does the 240-pin 8 GB stick produce when it runs all day?

At 1.50 V the module draws only the power required for DDR3 1066 operation; registered buffering adds negligible overhead, so heat output stays within standard DIMM thermal limits for enclosed server chassis.
