The “Cutting Edge” of bios modding
LAST MODDED July 11, 2020
Made with UEFI Tool v0.27 & UBU v1.79_4 Methodology shown in post #16
NVMe mod to run UEFI NVMe SSDs using module NvmExpressDxe.ffs dated 04/18/2018 which is 21Kb in size. All the rest is pretty standard ROM/EFI updates.
Enjoy your new NVMe capable modded bios with MDS/Meltdown/Spectre microcode updates.
BTW microcode v 28 fixes Microarchitectural Data Sampling (or MDS) side-channel vulnerabilities in Intel CPUs in addition to Spectre/Meltdown vulnerabilties.
As usual make a back up of your current bios and drives!
Dear @hancor Thanks for the BIOS firmware. I flashed it over BIOS Flashback. Everything was done successfully. The system was installed and booted without problems. One question. Ashampoo® Specter Meltdown CPU Checker gives an error when checking. My processor is vulnerable (i7-4770K). So it should be?
Hi @hancor Sorry for hijacking this thread, but I been trying to get my nvme m2 disc to work by following these steps but no luck. I have migrated my os to the new disc and I can see it as a new disk and (maybe wrong!?) assigned it with new drive letter. But it dont show up in the bios as a bootable (or otherwise) disc. I dont know if its possible to use it as a bootable disc at all? I have a Asus Z87 Pro mobo, flashed with your 2103 version, disc is Intel SSD 660p 1tb NVMe 3.0 x4 and a Adapter DeLOCK PCIe -> M.2 PCIe 3.0. What can I do to make it work or is it domed? Thanks for any info!
The NVMe SSD is bootable, but listed within the BIOS as “Windows Boot Manager”, this is where you do a CLEAN install of windows, without any other drives attached.
If you are not seeing the “Windows Boot Manager” in the boot tab of your BIOS/UEFI then you probably need to set the following:
NVME full functionality is achieved when CSM (Compatibility Support Module) is set to DISABLED in the boot tab, reboot, and then check the boot tab again.
If you have any other drives in the MBR (Master Boot Record ) format, you’ll need to convert them ALL to GPT (GUI Partition Table ) format, otherwise the UEFI will not “see” them.
Do your clean install of Windows 10 (the GPT version) to the “Windows Boot Manager” which is your NVMe SSD drive. If you check the link below at post #356, you’ll see what you are looking for in the UEFI boot tab (click on picture to expand) and why MBR and GPT drives don’t play nice together.
A friend of mine has this motherboard and it shows microcode v 25 in the bios…Is MC 27 any better for overclocking and temps,or is it just better to protect the cpu from vulnerability’s.Has anyone tested this modded bios out with regards to temps and overclocking compared to older microcodes…
I’ve tried on microcode v24, v25, and v27. v24, v25 do indeed have a performance penalty in the 5-10% region. v27 microcode is the more mature mitigation to Spectre, Meltdown, and MDS vulnerabilities; which from my own testing on Asus Z87-Deluxe resulted in a performance hit on the order of 0.5% - 1.0% which was a much better result.
On my Z87-Deluxe I was able to hit 4.7GHz on two cores and 4.6Ghz on the remaining cores with v27 microcode. Heat and temps not an issue.
Hi, I successfully flashed BIOS on my motherboard. I Installed windows, it’s booting fine but I have problem with sleep mode. Windows in not waking up from sleep mode at all. Do you have any ideas why it’s not working?
Also there is another problem. I can’t see NVMe in boot options. System is booting without problems but there is not NVMe option on list.
Try flashing the updated file and report back, on the NVMe issue make sure CSM (Compatibility Support Mode) in the bios is disabled and all your drives are configured GPT (Gui Partition Table)
Hi, @hancor thank you for the response. Sorry for the false alarm but sleep problem is cause by my GTX 660 GPU… Previously my father was using this computer and I wasn’t aware of this problem
Anyway thanks for updated bios. I flashed it already and everything works fine
NVMe disk is visible as boot device. I had to disable my HDD as boot devices and now NVMe is visible as only boot device. After that I have to reformat my HDD’s as GPT.
@hancor : When i update to the modded bios, of the ram work at 1333 and i when i try to configure it to work at 2400 Mh (throught Manual setting or XMP) it change nothing. When i go back to official bios - 2400 mhz works again.
I looked at neighboring topics (z87 bios modded) and many have the same problem. Could you fix it?
