johnvid Posted January 3, 2017 Share Posted January 3, 2017 Hello everyone, I've got a problem with my Unraid system. It says that IOMMU is disabled but the CPU supports VT-D and it is enabled in the bios. Does anyone know why this is? Link to comment

tdallen Posted January 3, 2017 Share Posted January 3, 2017 Are you sure the BIOS setting for virtualization is turning on VT-d rather than just VT-x? I know my P5B doesn't support VT-d, and support for it was very rare (if ever) during the LGA775 era. Link to comment
johnvid Posted January 3, 2017 Author Share Posted January 3, 2017 thanks for your quick reply. this old computer is my unraid test machine. To see how it all works before I reinstall my XPenology nas into an unraid version. but here is a screenshot of my bios. Vanderpool Technology should be the same as vt-d. Link to comment
tdallen Posted January 3, 2017 Share Posted January 3, 2017 I'm pretty sure that Vanderpool was the old name for Intel® Virtualization Technology, but that's VT-x. You need Intel® Virtualization Technology for Directed I/O to get VT-d support. Link to comment
johnvid Posted January 3, 2017 Author Share Posted January 3, 2017 That's a shame... Would a Intel 2500K work? Link to comment
JonathanM Posted January 3, 2017 Share Posted January 3, 2017 Pretty sure the motherboard is the issue, not the processor. Link to comment
tdallen Posted January 3, 2017 Share Posted January 3, 2017 The Q9450 supports VT-d, but the motherboard is the question/issue. Unfortunately the 2500k doesn't support VT-d. Link to comment
