✅ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility depends on your system’s processor platform, chipset, BIOS, DIMM population rules, installed CPU count, memory-bank layout, maximum supported memory per slot, and whether the board requires DDR ECC Registered memory. It is essential to verify your original memory label, server documentation, and supported DIMM type before ordering.

⚙️ Fit Notes

• Match your original memory part number whenever possible
• Confirm your system supports 2GB 2Rx4 PC-3200R ECC Registered DDR memory
• Confirm your board uses 184-pin DDR RDIMM slots
• This memory is for registered / buffered ECC server platforms only
• This is not for standard PC-3200 desktop DDR, unbuffered DDR, SODIMM laptops, or PC2 / DDR2 / DDR3 / DDR4 systems
• This is also not the correct module for PC-2700R-only platforms unless the board specifically supports PC-3200R downclocking
• Many older servers are sensitive to rank, chip organization, and buffered vs. unbuffered differences
• For best stability, use matching capacity, speed, rank, and type across memory banks whenever possible
• Some systems require memory to be installed in matched pairs, matched quads, or balanced CPU-local banks
• On many multi-socket Opteron boards, memory slots are attached to specific CPUs; if a CPU socket is empty, its related memory banks may be disabled
• Some legacy systems may require a BIOS update for full 2GB DIMM support
• If the system does not boot after installation, confirm DIMM seating, bank population order, CPU population order, BIOS support, and mixed-memory compatibility
