HP 733481-001 Compatible Server Upgrade

This 8GB DDR3 1866MHz ECC Registered DIMM is a direct replacement for the HP 733481-001 part number. It targets administrators maintaining compatible HP server or workstation platforms that require registered error-correcting memory. The single module delivers 8GB capacity at PC3-14900 speed with CL13 latency.

Standard Voltage Registered Operation

The module runs at the DDR3 standard 1.5V with a registered buffer that reduces electrical load on the memory controller. ECC functionality detects and corrects single-bit errors to protect data integrity in continuous server workloads. The 2Rx4 organisation spreads density across two ranks of x4 devices for stable signalling.

Validated Module With Lifetime Coverage

Each stick undergoes A-Tech quality-assurance testing before shipment to verify reliable operation in the target systems. A lifetime warranty covers the module for as long as you own it, and US-based technical support is available for compatibility questions or troubleshooting assistance.

Questions about this item

How do I install the 240-pin DDR3 RDIMM and which step is often missed?

Align the notch on the module with the slot key, press straight down until both side clips click, then verify the system recognises the full 8 GB at 1866 MHz in BIOS or the OS memory report.

What maintenance or replacement will this ECC RDIMM need over its service life?

No routine maintenance is required; the module either passes POST and runs error-free or it fails, in which case the single 8 GB stick is replaced as a unit.

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

The DDR3 1866 MHz speed and CL13 latency set the throughput ceiling; sustained workloads will hit that bandwidth limit before voltage or thermal constraints become an issue.
