两张3090涡轮的声音还可以接受 比我3d打印机安静很多<br />
只是我接受不了那个热气<br />
选双路因为那个NVLINK (暂时没发现多大用处）单路的nvlink 2/3slot 距离都不适用</p>
<p dir="auto">整了1个小时多放弃了 才装上Ubuntu<br />
一开始还是 手动问ai 一句我做一步<br />
后面懒了 直接交给claude code</p>
<p dir="auto">还有一点就是，刚好跟同一家买，卖家测好发货<br />
不然我就踩了NVLINK间距的坑, 卖家测了不能用 就跟我说 结果还帮我找2slot nvlink连接器 换了PCIE 间距适合的 主板（当然花更多钱了）<br />
意外收获的是，因为升级主板买到带有IPMI接口的 所以可以远程开关机 省点电费</p>
