⚙️ Fit Notes

• Confirm that the system requires a 184-pin DDR1 desktop DIMM, not a 200-pin laptop SO-DIMM.
• This is non-ECC, unbuffered memory. It must not be substituted for ECC, registered, or fully buffered memory.
• Do not mix this module with 168-pin SDRAM, 240-pin DDR2, DDR3, DDR4, DDR5, or other physically incompatible memory.
• Motherboard and BIOS support for a 1GB module is required. A compatible connector alone does not guarantee that the system supports 1GB per slot.
• Low-density x8 organization is the safest option for many early DDR chipsets. Buyers requiring a specific rank or chip organization should confirm availability before ordering.
• When different memory speeds are mixed, the system normally operates all installed modules at the slowest supported speed.
• Some dual-channel systems require or strongly recommend matched modules installed in pairs.
• The original 1.6GHz G5 configuration requires matched memory pairs. This listing includes one module unless otherwise stated.
• Do not mix ECC and non-ECC modules in systems capable of supporting both types.
• Transfer no heat spreader, retention clip, or other hardware unless required by the original system.
• Power off and unplug the system before installation, and use proper electrostatic-discharge precautions.
• Actual manufacturer, label, PCB color, memory-chip count, rank, and revision may vary according to available stock. Customers requiring one exact part number or physical layout should confirm before purchasing.
