⚙️ Fit Notes

• Match your original memory part number whenever possible
• Confirm your system supports 16GB 1Rx4 PC4-2933Y DDR4 ECC Registered RDIMM modules
• Confirm your server or motherboard uses 288-pin DDR4 RDIMM memory
• Install memory according to the system manufacturer’s DIMM population order
• For best stability, use matching memory modules across channels when possible
• Memory speed may run at 2933, 2666, 2400, or another supported speed depending on the processor, BIOS, and DIMM population
• Do not use in systems requiring UDIMM, LRDIMM, SODIMM, NVDIMM, or desktop non-ECC memory
• For Dell systems, verify the original Dell memory rank and part number carefully before ordering, as some 16GB 2933 configurations use a different rank layout
• Always power down the system, disconnect AC power, and follow proper ESD safety procedures before installing memory
• If the system does not boot after installation, confirm DIMM seating, memory population order, BIOS support, and mixed-memory compatibility
