Axiom 8GB DDR3 ECC for IBM Systems

This Axiom 00D4959-AX module provides 8GB of DDR3 1600 memory with ECC error correction. It is built for IBM System x3100 M4 and x3250 M4 servers. The unbuffered design suits platforms that require non-registered DIMMs.

240-Pin DDR3 1600 Unbuffered Specification

The module runs at DDR3 1600 (PC3 12800) across 240 pins. ECC functionality detects and corrects single-bit errors. Unbuffered signal processing means it will not work in systems that require registered or load-reduced DIMMs.

Suited for Compatible IBM Servers

This memory suits administrators upgrading or repairing the listed IBM models with verified unbuffered ECC modules. Buyers whose platforms demand registered DIMMs or a different DDR generation should look at other parts.

Questions about this item

What does the 1600 MHz speed rating mean when the module is installed in a server?

The DDR3-1600 clock runs at 1600 MHz, so the memory controller can transfer data at the PC3-12800 rate, improving throughput for database and virtualization workloads on supported platforms.

How does the 240-pin DDR3 interface affect what the module can do?

The 240-pin DDR3 DIMM fits only DDR3 slots and operates as unbuffered ECC, meaning the memory controller talks directly to the DRAM without a register, capping capacity per channel to the module's 8 GB limit.

What physical clearance does the 157.5 mil thickness require in the chassis?

At 157.5 mil thick, the DIMM needs standard DDR3 slot spacing; it fits IBM System x3100 M4 and x3250 M4 boards without interfering with adjacent components or heatsinks.
