The Rampage IV Extreme Intel® X79-based motherboard features tons of revolutionary overclocking features for enthusiasts to set new world records. The first is getting TRIM to work under RAID using the original, unmodified ASUS UEFI BIOS (i.e. Without a patched OROM) as BIOS version 3404 on the Rampage IV series has the Intel UEFI driver. The second reason is speeding up Windows boot as only with a UEFI installation you can completely disable CSM (compatibility support module).
Asus Rampage Iv Bios
Hi,
I am still using my ROG Rampage IV Extreme and am 'extremely' happy with it
I have come across an issue that I am unable to resolve on my own. The I/O connector at the back of the mother board has four USB 3.0 connectors labeled as 1 through 4. USB 3.0 connectors 1 & 2 work fine. I am having issues with connectors 3 & 4. When I connect any USB device to either USB 3 or 4 nothing is detected by the OS (Windows 10). The connectors are 'alive' in that, if I put a thumb drive into either 3 or 4, the drive indicator light turns on but, still, the devices are not detected.
I have looked through the bios setup screens and all ports are enabled except for USB 13 which says the bios says is not in use.
Any idea why USB 3.0 #3 and #4 are not working or otherwise inactive? Could plugging in USB connectors to other motherboard connectors have disabled these two connectors?
Any thoughts would be much appreciated!
Joe
