12 hours ago12 hr Hello everyone,I'm looking at various plugin and information about my server. It is a Dell Precision 5820 with a Xeon W-2275. According to specs, it has all PCIE Gen 3 slots. But looking at lspci output and various other plugin like hbaviewer and GPUStats, they are reporting connected as Gen1 speed but Gen 3 available. Does anyone know how to enable it to be on Gen 3? Both card connected are Gen3.Thank you

8 hours ago8 hr Author So I got sold something that isn't what spec on the seller page if I understand correctly, cause they say it's a PCIe Gen 3 x8. But if it's gen 2, why does it connect at gen1 speed? Edited 8 hours ago8 hr by Nodiaque
8 hours ago8 hr Community Expert SAS2008 is PCIe2 so if it was listed as Gen3 that'd have been a listing error Edited 8 hours ago8 hr by Kilrah
8 hours ago8 hr Author I'm unsure if it's really an error, the whole page on amazon speak of gen 3, even the title say gen 3. It's been far too long for me to return. But shouldn't it show gen 2 and not gen 1?

8 hours ago8 hr Author Oh I don't contradict your information, I did found out the broadcom information about the LSI SAS 2008 which says it's PCIe Gen 2 (https://docs.broadcom.com/doc/12352283)So it's the plugin that is in the wrong then, cause it shows as 2.5gbps But the NVidia is downgraded to PCI gen 1 thoughLnkSta: Speed 2.5GT/s (downgraded), Width x16
