The ASPM setting do nothing on my system that I can find. I tested all of them for several days each. Same with the ErP Ready setting - nothing. I have both hardware switches off. And, I don’t have Asus utilities loaded on my system. I found them buggy.
My PCIe NVMe drives work at full NVMe 3.0 x4 speeds but no power management in Win 7 or 10
Also, I would add a USB 3.0 card. But, I only have a PCIe 1x slot available. I think this motherboard supports 1/2 USB 3.0. Not full USB 3.0 speeds. About 1/2
More than enough bandwidth for the USB3.0 card addon.
The USB3.0 on this mb comes from the ASMEDIA ASM1042 chipset on her, not from Intel X79 chipset.
Several FWs avaible for it, from Asus officially and 3rd party, as drivers also.
I am using a direct connection (no hubs) to the USB 3.0 ASMEDIA ASM1042 ports. The speeds I get are many times faster than USB 2.0. Plus, the ports are clearly noted in the manual. Right now, I am using the ASMedia USB 3.0+3.1 Drivers & Software Set v1.16.61.1 WHQL.rar Driver. I find them a little slower than the old driver ASMedia Technology Inc, 8/16/2013, 1.16.12.0. I think the problem is the link to the motherboard. About the same speed as a USB 3.0 card hooked into a 1x slot - It even has that in your image 1x. I think USB3.0 should hook to a 4x link. Or, you will get 2.5 GT/s. Just like my speeds are. Thanks for the image.
Correct me if I am wrong
Its Asus design to link the ASM into the mb PCIe bridge.
The image was from my older P9X79 HWinfo report.
I advise you to update the firmware for the ASM1042 chip:
Download MPTool Version 1.7.1.2
Latest firmware: 130125_00_02_00
- Run ASM3142_MPTool.exe as “Administrator”.
- Enter password “Asmedia” on ASMEDIA MP Tool windows.
- Check “Firmware Upgrade Enable” and Check “Firmware Check Enable”
- Choose the file on package "210330_70_02_40.bin "
- Press “Start” below to processing.
- When finish restart Windows 10/11 once to running new firmware.
If you are using Windows 11, I found it better to use the standard USB driver from Windows Update rather than the latest driver from ASMedia. On the ASMedia driver, several devices connected to the HUB in the monitor, e.g. the fingerprint reader, do not work. Everything works with the Microsoft driver.
