Server Memory for DDR2 ECC Platforms

Axiom AX2533E4S/2G is a 2GB DDR2 533 (PC2 4200) ECC Unbuffered DIMM built to a 240-pin form factor. It operates at 1.80V with a CAS latency of CL4. The module is validated for Gateway E-9220, Intel Desktop Board D955 and D975, Server Board SE7230 and SUPERMICRO PDSG4 systems.

Suited for Legacy Servers and Workstations

This module fits administrators maintaining DDR2-era servers or workstations that require ECC unbuffered memory. It is not for systems that only accept registered DIMMs, platforms needing higher density than 2GB per slot, or boards limited to non-ECC memory. Buyers without a compatible DDR2 ECC platform cannot use this part.

240-Pin DDR2 533 ECC Unbuffered Specification

The decisive specification is the 240-pin DDR2 533 (PC2 4200) ECC unbuffered interface. Only motherboards with DDR2 slots that support unbuffered ECC at this speed and pin count will accept the module. Verify the board manual for DDR2 ECC unbuffered compatibility before ordering.

Questions about this item

How do I install this 240-pin DDR2 module and what step do people miss?

Align the notch with the slot key, press straight down until both retaining clips click, then verify the server BIOS detects the full 2GB at 533 MHz.

What maintenance or replacement will this ECC unbuffered stick need later?

No routine maintenance is required; replace only if memory diagnostics report correctable errors rising above threshold or a DIMM fails POST.

What limit appears first under sustained load with this CL4 1.80 V module?

The DDR2 533 bus bandwidth and CL4 latency ceiling constrain throughput before voltage or thermal limits become factors.
