This line is supplied to your required quantity from Shenzhen. The lot is graded and tested in Shenzhen before shipment. Pricing is fixed as listed. For every order, request a quote with your target volume and delivery address and we confirm the quantity, the unit price and the shipping window in writing.

Compatibility is decided by your platform, not by the part number alone: 4 attributes decide fit (form factor, capacity, rank and speed), plus ECC support where the platform requires it. UDIMM in the DDR5 class must be matched against your platform's own requirements before ordering — memory compatibility is determined by the server or workstation it is installed in, not by the part alone. The attributes that decide this are form factor, capacity, rank, speed and ECC support. We do not claim compatibility with any specific system model, because the same part number can behave differently across BIOS revisions and configurations. Send us the platform make, model and firmware version with your enquiry and we will tell you plainly whether this lot is a match, and flag any attribute that needs confirming.

2 modules with identical part numbers can differ several-fold in price, entirely because of history. New stock carries the lowest risk and the highest cost. Pulled-and-tested stock has been removed from decommissioned equipment and verified functionally, which is why it is the usual choice for buyers who need working parts at a fraction of new cost and who accept normal signs of prior use. Refurbished stock sits between these categories: cleaned, inspected and functionally verified before packing.

因此，成色等级本质上是关于由谁承担风险的决策，而不是判断器件好坏的问题。拥有测试台、并能容忍较低故障率的买家，可以选择更低等级以显著降低单价；无法承受故障后果的买家，则应为更高等级付费。我们在每份报价单上都注明等级，让这一选择明确可见，而非靠默认暗示。
