Problem persist on VII hero. There are no solutions that makes sense. Disabling asmedia ports doesn't fix anything. It's not a "to many usb devices" issue. It may be a general usb issue, it may be AIO cooler that halt up system, in that case it's the same for both h100i and kraken x61. I have tested optional mouse/keyboard that works perfectly on different comp without any difference. The USB devices are fine, including AIO cooler.
I have had more success disconnecting network cable. Not thoroughly tested, but it passed numerous tests, its getting easy to reproduce the error, which is inconsistent. Like 1/3 of boots are slow.
Everything points toward MB and win7. I put my fist to the table and say: This MB is NOT compatible with win7. I'm even currently having a new issue, getting exclamation mark on AMDA00 Interface. Some component of Asus for AI suite. I don't use AI suite (doh), it's labeled as a resource for win8.1.
Another highly likely cause of issues are intel's treatment of Samsung SSD where obviously you don't want to be running IRST, but MB require components from IRST forcing you to install it anyway. Works fine to uninstall it afterwards, but there's no effect on performance, which is strangled to a slow by intels' incapability of making functional drivers to their hardware. You don't even need the MB drivers installed. I have been greeted by the error before installing any drivers, and on loading WINDOWS INSTALL boot from bios.
So not surprisingly I conclude this MB is NOT win7 compatible. I'm looking at having a expense equal to the MB's value to have retailer confirm my suspicion. Really. IDK what windows is doing, but it could be that it tries to go online looking for sense on usb drivers, or something. I'm not surprised that it struggle with AIO coolers. This board should however be 100% compatible with them and there should be no performance impact. If there is, exclusively for win7. That's incompatibility.
That being said. System works 100% otherwise. OK memtests, passing benchmarks etc. This doesn't excuse the other issues though. Incompatibility have been proved long before starting any benchmark.
So yea, I am likely to RMA this board due to no win7 compatibility.
Ironically I RMA'd two Asus GPU's originally bought together with this board for not being 8.1 compatible. 8.1 didn't want drivers for them at all, was stuck with microsoft gpu driver. The GPU's were labeled 8.1 compatible. Just another proof that Asus ship out high end hardware that have serious compatibility issues. The GPU's carried a old chipset which were not compatible, but despite that Asus had labeled them otherwise.
