Cheap AMD motherboard with IOMMU/AMD-Vi support - Page 2

post #11 of 23
Thread Starter 
I can't buy anything Intel, it's too expensive. All I need is a motherboard for AMD that I know have full IOMMU support including ACPI-IVRS. Also you live in another country than me, in Norway you can't get ANYTHING "locally". Have to buy everything over the internet. The board itself doesn't have to be dirt-cheap, I just need something which works! tongue.gif

Yeah, I know that hardware isn't always easy to find in other areas of the world, which is why I asked.

I think your best bet is to just start emailing tech support of some companies that you know you could buy and just ask. They likely have a beta BIOS laying around that works fine and has everything enabled, but you are going to need to ask for it.

I did see this:
Quote:
Motherboards with a beta-bios available from tech-support that supports the IOMMU:
Gigabyte GA-890FXA-UD5
Gigabyte GA-890FXA-UD7
MSI 890FXA-GD70 (from beta-bios 1.75 reported working by Sander Eikelenboom)

Edit: Ruled out, no one of my suppliers has them. Also mailing techsupport, sigh. I will grow old and stupid before I get any response from them. I did post on another forum, let's hope they can share their knowledge. Any other places I should go look?

I've heard of people flashing the MSI 890FXA-GD65 with the GD70 BIOS...that might enable the IOMMU option on it. So you might want to check into the availability of that board.

Any forum that specializes in Virtualization.

VMware and Xen.org come to mind...but those are just the places I frequent.

You might find help over at BIOS-Mods.com as well

After searching for what seems like to be a needle in a heystack, I finally found a motherboard that |might| fully support IOMMU. The GIGABYTE GA-990XA-UD3 should, as per this review support it fully using ESXi.

Newegg.com - GIGABYTE GA-990XA-UD3 AM3+ AMD 990X SATA 6Gb/s USB 3.0 ATX AMD Motherboard - review #9

Does anyone know anything more?

I haven't had that board first hand, but if you look at page 43 of the manual it shows a screen shot of the IOMMU switch in the BIOS

I think you have a winner there if it is available to you and in your budget. Though be careful, that board needs to have BIOS version F4 or newer to support a FX CPU. You might need to have a AM3 CPU to flash the BIOS with unless it comes with the newer BIOS on it.

Try to find the GIGABYTE GA-970A-DS3 as well. it apparently has it and should be a good amount cheaper. Though it will not have the power to overclock a FX8150...only 4+1 phase power. One of the downfalls of the FX8100 series, but left at stock, or close to it, I think it would be OK. They will need a decent motherboard. I have used the DS3 with Phenom II CPUs, but not an FX....(and there was no virtualization used so I never looked to see if it had it first hand, manual says it does though) and I've always had good luck with it.

There might be more Gigabyte boards with it too...

Yeah, the GIGABYTE GA-970A-DS3 is cheaper, but the problem is that I have no idea whether it has the ACPI-IVRS table needed for full IOMMU support.

I built a small business server with a ASUS Crosshair V and it could do it out of the box, but that was not a cheap board.
If you don't have the CPU yet...I don't think it is possible to buy an Intel board without VT-D. It would mean you've have to at least buy a 2600K to get eight threads though

The "k" series CPU's from Intel all have VT-D disabled. Only the Non-K versions have it enabled

2600k: http://ark.intel.com/products/52214/Intel-Core-i7-2600K

2600: http://ark.intel.com/products/52213

I have no idea why they would do this.

I had the Gigabyte 970A-UD3 and it supported IOMMU and Virtualization plus supported my non-buffered ECC dimms just fine. Even had ECC settings in BIOS.

Not sure on the ACPI-IVRS. I don't even know what it is. lol

I had ESXi 5.0 running and 4-5 VMs with no issues. I only sold it as it cost too much electricity to run it 24/7 for my home server and bought a tiny little HP Micro Server N40L. Now I use 35ish watts at idle instead of 150ish watts. lol

Wasn't talking about CPUs...only mother boards. I don't think any Intel motherboards will not have the switch. It will just be grayed out if the CPU doesn't support it. VT-x will do the same job anyway save for GPU pass though. You need VT-d for GPU pass through.

As to why they would do it? To get customers to stop saving money by not buying high priced Xeons
