I took this at face value until reading the moderator response
here. Now I've stopped looking for a non-Supermicro motherboard, to being thoroughly confused on which person is right.
Since I'm the person who is apparently confusing you I thought I'd take the chance to reply
When I wrote this, I had looked at using the SuperMicro motherboards as they could handle large amounts of memory. I did as much research as I could at the time as I was interested in running very large databases and 256GB of RAM was attractive to me. The research I did indicated that the BIOS is use for Supermicro at the time (which was two years ago) was non-standard. I know that Supermicro makes great motherboards, which is why we wanted to use them, but the research I did showed that the BIOS was slightly modified to take advantage of the different motherboards.
As I said at the time "I do not know how they present their information to the OS and whether you can make assumptions about what is happening deep down. e.g. will theFakeSMC stuff work". To the best of my knowledge that is still correct, I cannot state with 100% certainty as I do not have a motherboard to test this out on.
I also recall that some graphics cards may not work as these motherboards are often designed for large lights out data centres, where running a powerful graphics card is not needed, or indeed any graphics card.
The fact that Supermicro sends out it's own BIOS upgrades on a key could well indicate that the BIOS is non-standard.
I also stated that you would be in a small minority if you did do this work but I'd love to see it working. However I do not have the time to make it work, nor possibly the skill. I pointed out that this could be hard work.
I've read through my e-mail and I still stand by what I said at the time. It may well be that this is a perfectly simple build. Brilliant, but I wouldn't want somebody coming back to me saying that I'd caused them to waste many hundreds of pounds and hundreds of hours getting a board that will not work. I pointed out that I have an IBM p-Series for big databases as that works very well, for me.
My personal view then is that if you could afford the RAM to stuff an MB with 512GB, I'd buy a real Mac or a big server and run Linux on it. Its a massive amount of money to gamble on an unknown system. I still stand by that view for my money.
You are welcome to take my advice or leave it. Its worth exactly what you paid for it. Nothing
"The reason I pointed out the BIOS is that Supermicro run their own BIOS system and have their own components further down the hardware chain so they are not the same as the more common BIOS/UEFI systems available through desktop vendors. I do not know how they present their information to the OS and whether you can make assumptions about what is happening deep down. e.g. will theFakeSMC stuff work, there are lots of 'delicate' shims used to make things work in the Hackintosh world and if something isn't quite normal then stuff just doesn't work, certain graphics cards being a good example. Also as I recall any BIOS changes have to come directly from Supermicro on a special key."
