Hi Fernando, thank you for looking into this. Yes, I am sure I’m following your guide. Under Step 1 - Preparation, the third bullet is:
*Only for ASUS BIOSes with the suffix .CAP
My motherboard is an ASUS P9x79 and the latest version of the BIOS file from Asus is called “P9X79-ASUS-4801.CAP” which has the suffix .CAP so I followed the steps outlined in that section using the UEFITool as outlined in the guide.
Is this step unnecessary? I’ve zipped the modified BIOS file and attached as you recommended.
Thanks again, I’m new to this and still learning so apologies if I’m overlooking something obvious.
@Fernando I’ve followed your steps and ignored the 'Extract the body of the original *.CAP BIOS". After I inserted the module, I got a message “Saving secure capsule as unsigned” in the MMTool (v5.0.0.7). Is that an issue? I’ve attached a screenshot and a copy of the resulting BIOS file.
I have been using the bios Asus Bios P9X79-4701-Mod-NVME-SA-Switch. I have a date of 1-19-19. It works great, I have no performance issues. Other than, I need to keep the surge setting disabled. And, that may be my power source because I have a good power supply.
My question is: Is there a PCIe bios setting keeping my drives from going into sleep mode? I never messed with the PCIe settings.
PCIe settings like ASPM would only have impact on disks connected to a PCIe card storage controller, in this motherboard, other than this edit your power plans in Windows regarding disks.
Some hdd’s power management can also be changed/balanced with some disks utils.
Well, Auto ASPM did nothing. I am using Intel 760p drives with the 760p Solid State Drive Client PCIe drivers. The white paper states it supports both levels of PM. I tested other drivers as well.
I came here because this is the P9x79/ NVMe place where I received the bios
Why didn’t you mention this initially… what i wrote are for standard HDD disks on internal SATA chipset of the motherboard.
Modern SSDs and NVMe disks are often managed by their internal controller and driver if specific OEM model is used/required, not using MS OOB standart drivers.
ASPM is very often disable by default in bios, cause they cant deal with all kind of hw devices, brands and models around in the market.
So its you choice to engage them and see how the system/power management reactes, some do not even boot when some ASPM seetings are modified or some power managment apps stop responding…resuming enabling ASPM in certain systems configurations can be very unstable, specially desktop user builds.
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
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.
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.
I wanted to try the bios posted 2 Aug 24 with the Microcode updates . But after I flashed to 4801, “NVMe mod only” posted 1 Aug 24, EZ flash no longer works. Even though, the rest of the bios seems to work fine. Just no more EZ flash (USB Method). Would AFUDOS work with this motherboard ?
Since no one else, besides you, has not reported such lost feature using this file, i’ll leave it still posted for now…
All the Asus mod files, primarily is NOT intended for flashing using AMI tools or Asus embedded tools, we came to the conclusion (Guide) that the best way to bypass securities was using the USB BFB feature in all the mboard models that contain this feature.
So, if you want to try other mod files, USB BFB is the method to be used.
If I knew it was the bios file, I would flash in the bios to an official file. Then, run EZ Flash. But if it is the hardware button, I would be stuck with no NVME support.
AFUWINx64.exe looks like it works but it does nothing. Secure flash error
I attempted the commands:
Afuwinx64.exe P9X79.rom /GAN
AFUWINx64.exe P9X79.rom /P /B /GAN
AFUWINx64.exe P9X79.rom /P /B /GAN /R
