这个料号是什么？
This is a 12.00 GB Other module, built with NVIDIA memory. Additional attributes recorded for this lot: Warranty 1 year; Packaging New retail box (sealed).
这批货品的成色如何，又是如何测试的？
每一批次使用4个等级之一；这一批被评为 全新. Factory-new modules ship sealed, exactly as they leave the factory; OEM warranty terms, where they exist, pass through from the manufacturer. Every quotation we issue states the grade, the test status and the physical condition of the lot, so that what you receive matches what you were quoted.
有多少现货，交期是多久？
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.
这批货兼容什么？
兼容性由您的平台决定，而非仅由料号决定：4项属性决定是否适配（外形规格、容量、Rank和速度），平台要求时还需支持ECC。Other在下单前必须与您平台自身的要求进行匹配——内存兼容性由所安装的服务器或工作站决定，而非仅由料号决定。决定兼容性的属性为外形规格、容量、Rank和速度。我们不宣称与任何特定系统型号兼容，因为同一料号在不同BIOS版本和配置下可能表现不同。询价时请提供平台品牌、型号和固件版本，我们将明确告知本批货是否匹配，并标出任何需要确认的属性。
下单前需要核对哪些事项？
决定这样一批货是否适合你的平台有3个属性，这3个属性都可以从你的平台文档中查到，而不是仅从内存条本身得知：
- 外形规格与防呆缺口。 一个模块相配的槽由平台决定,在机械相容的变体中也存在同样的容量. 在比较价格之前确认底盘接受哪个。
- 每通道秩数与容量。 容量通过组合多个秩来实现，而某些平台会限制每条通道可寻址的秩数上限。即使某条内存模组在电气上完全正确，一旦超出该上限仍可能不被支持。
- 速度与ECC支持. 当平台或其余通道无法达到模组额定速率时，实际运行速度会被协商下调，因此更快的模组并不保证运行更快——它保证的是余量。
询价时请一并提供平台品牌、型号和固件版本，我们会对照该批次进行核对，并明确告知是否兼容，而不是让您自行从列表中推断。
等级如何影响价格与风险？
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。
