Two Wire Posted July 12, 2014 Share Posted July 12, 2014 Will the ASRock Z97 Extreme6 LGA 1150 with the Intel Core i5-4670 Haswell Quad-Core 3.4GHz be compatible for implementing vt-d. The board and cpu are located here http://www.newegg.com/Product/Product.aspx?Item=N82E16813157500&SortField=0&SummaryType=0&PageSize=10&SelectedRating=-1&VideoOnlyMark=False&IsFeedbackTab=true#scrollFullInfo and here http://www.newegg.com/Product/Product.aspx?Item=N82E16819116898 Sorry for the above. I did not know how to hide the lengthly url's. Link to comment
garycase Posted July 12, 2014 Share Posted July 12, 2014 Should be fine, although it depends on whether or not AsRock has crippled the vt-d setting in the BIOS. MOST modern boards don't have any problem with this as long as the CPU supports vt-d (which the one you've selected does). Link to comment
bkastner Posted July 12, 2014 Share Posted July 12, 2014 Should be fine, although it depends on whether or not AsRock has crippled the vt-d setting in the BIOS. MOST modern boards don't have any problem with this as long as the CPU supports vt-d (which the one you've selected does). ASRock is usually one of the better manufacturers for VT-D compliance. ASUS usually cripples/screws up things, and many other manufacturers are iffy. ASRock and SuperMicro seem to be the best bet to ensure compliance with the specifications (from what I've seen anyway).

garycase Posted July 12, 2014 Share Posted July 12, 2014 Definitely agree that SuperMicro is very good at full spec compliance. I've not had any issues with Asus boards either, although I've read some complaints. In my experience it's usually because Asus (for some unknown reason) sets the defaults in the BIOS to disable vt-x and vt-d ... and it's not always obvious where to change those. But once enabled, the features work fine. Link to comment

But once enabled, the features work fine. ASUS has always been my board of choice, but there was enough noise around VT-D compatibility that I skipped it for my UnRAID box. From what I've read various BIOS builds can break the functionality even if it's enabled, and so I've moved to ASRock and SuperMicro for UnRAID and XenServer machines to be safe. Also, from those who've contacted ASUS they don't appear to get great support on this feature, so again it's a reason to not even bother going down that road unless you have a very good reason.

garycase Posted July 12, 2014 Share Posted July 12, 2014 ... it's a reason to not even bother going down that road unless you have a very good reason. Agree. My UnRAID boxes all use SuperMicro boards. They seem to be the most spec-compliant manufacturer, and the small price difference to use their boards is well worth it for both this and the rock-solid nature of their boards. Link to comment
Two Wire Posted July 12, 2014 Author Share Posted July 12, 2014 ASUS has always been my board of choice, but there was enough noise around VT-D compatibility that I skipped it for my UnRAID box. Same here, and that is why I'm looking at other options. gytroyp, in the virtualization forum (known good Xen hardware configs) is using practically the same board with success. It's using the z87 chip set, however. I used this as a guide in my selection hoping it would work with either Xen or KVM. I did a small search for an up-to-date Supermicro board, but tired out after a while. If anyone knows of a Supermicro board using the Z97 chip set that would work as an option for my purposes I would appreciate it much. My problem is not many manufactures indicate in their specs if the board is vt-d compatible. Therefore, just knowing enough to be dangerous, I find myself relying on the experiences of others as protection aganist myself. I have used the same MB since ver. 3 and updating to ver. 6, and virtualization, has energized me. I will have to find a IDE controller, however, to use some of old drives, though. Thanks all, for the input. Link to comment
jumperalex Posted July 12, 2014 Share Posted July 12, 2014 catch-22 for me is that other than supermicro ... most consumer boards don't support ECC ram, but Asus does. Unless you need 100% iommu support then asus might be worth it.

Two Wire Posted July 13, 2014 Author Share Posted July 13, 2014 Thanks all, for the help. I found some suitable Supermicro boards, but not being that "mission critical" here, I decided to purchase the Asrock board and use standard memory. I will post my results in the virtualization forum when I put this together. Thanks, Jerry Link to comment
