GA-EP45-UD3P owner, 18 months. Bugs in the USB circuitry prevent using multiplexed wireless keyboard / mouse combos in DOS programs like diagnostics, drive partitioning tools, etc. You can get them to work by enabling "legacy support", but that has the side effect of making your thumb drives, digital cameras, etc. inoperative in Windows! Furthermore, the USB channels have a bug which causes them to continually drop from 2.0 to 1.1 speed.

The built in SATA RAID is a joke. Gigabyte advertising is not honest. They should tell customers that RAID arrays configured on either the Intel or Gigabyte SATA ports cannot be partitioned for multiple OS systems. Not only that, but you cannot setup a RAID array unless you choose to install Windows. And even then it's doubtful Windows can manage the non windows partitions in the array.

They also have built in bugs in their Firewire support for external drives.

Gigabyte tech support has spent more time telling me what the board WON'T do than helping me fix it. I bought the board because it was supposed to be flexible and could be tweaked for maximum performance. I haven't even attempted to tweak it. I've been too busy just trying to get it to work.

While I sympathise you've been butthurt through things continually not working - we've all had those days - you've dug up a year old thread to moan about chipset limitations not Gigabyte limitations.

Leaving USB Legacy Function enabled makes the USB work normally for me in Gigabyte boards. It's always on by default and that's how we test it.

I've never ever had any modern board drop between 2.0 and 1.1 to be honest - could it not be your devices plugged in? I've not tested the Firewire but the chipset is standard across many boards - maybe that is a genuine BIOS issue perhaps.

While the multiple OS partitions issie is somewhat surprising, it isn't - basic RAID is what you get on any board, Gigabyte or otherwise: they all use the same chipsets. Plus this is a UD3R - virtually vanilla. If you were dishing out $700 for a UD9, yes, I'd expect far more. Honestly it's not something we test because it's never asked for though - we never recommend using onboard RAID anyway other than extra SATA ports. I'm very surprised that you cannot setup a RAID array and only installing Windows - is that not a case of the other OS' not having the necessary drivers to see the chipset?

I strongly suggest you simplify what you want to do. If Gigabyte say the board can't do it, then it can't do it - it's a mass market product and you're unfortunately in the niche end of the spectrum. I'd put money on the fact that Asus or MSI would give you exactly the same answers.
