8GB DDR3 ECC RDIMM for IBM-Lenovo Servers

This 8GB registered DIMM runs at DDR3 1066MHz with CL7 latency and 1.50V operation. It is built as a 2Rx4 module using major-brand chips and carries ECC for data integrity. The part replaces IBM-Lenovo 44T1578, 44T1579 and 4529 modules in compatible server and workstation platforms.

Standard voltage DDR3 thermals and power

Operating at the standard 1.50V for DDR3, the module draws typical power for registered server memory at this speed. The registered buffer adds minimal overhead while improving signal integrity on multi-DIMM channels. No active cooling is required beyond normal chassis airflow in supported systems.

Tested compatibility and lifetime support

Every unit undergoes quality assurance testing before shipment to verify reliable operation in the listed IBM-Lenovo systems. A-Tech provides a lifetime warranty on the module and offers US-based technical support for installation questions or troubleshooting. Buyers who need different capacities, speeds or unbuffered ECC should verify their platform requirements before ordering.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 8GB module is detected at 1066MHz with ECC active.

What maintenance or replacement will this 8GB ECC RDIMM need over time?

No routine maintenance is required; the module either continues operating or develops correctable errors that ECC handles, and replacement is only needed if uncorrectable errors appear or a capacity upgrade is desired.

What limit appears first when this 1.5V DDR3 RDIMM runs under sustained load?

The registered buffer and 1066MHz bus set the throughput ceiling, so sustained workloads hit the 1066MHz bandwidth limit before voltage or thermal constraints become a factor.
