Does anyone know if it will work on the GA-Z77X-UD5H (it should) - I would gladly go with this solution.
I will be grateful for every help. //Mojave + Clover

I think with even the official BIOS updated the UD5H is bootable.

Question for all the UD5-TH users, I’m on F12j and have been for years. I read a comment saying I’d need to flash to OP bios to get nvme support from bootable pcie.

Has anyone made a f12j with the additional bits in the bios? Effectively an F12j + nvme support? Or is that basically what the OP did?

Or did the OP make his bios image from the official F12 source?

Thanks for all that information.

Has anyone managed to if it’s even possible made an Optane drive work along side this?

We have effectively made our old boards bootable from PCIe NVMe. GG to all involved.

I’m aware that Optane was only intended at release for Boot Drives and not much point for an NVMe, afaik.

However, Intel did release an update which enabled Optane users the function to use Optane on other volumes.

I was hoping to be able to achieve this.

500GB PCIe NVMe Boot
2x500GB SSHD in RAID with a 32GB Optane cache.

Doable?

Can the GA-Z77X-UD3H change the BIOS for that mainboard? thanks.

danmcq, your modified BIOS worked like a charm. BTW, I asked if you would please modify the F12J BIOS is because I don't have Windoze installed on any of my systems, and, thus, can't make the change myself. TIA.
Hi Stork,

I'm going fishing here, but thought I'd throw it out there. Have you heard of any similar BIOS patches that would afford similar upgrades for older chipsets, specifically for the meltdown and spectre exploits for z68 systems? I had contacted Gigabyte about them and they had reassured me that when Intel issues the patches, Gigabyte would put out the updated BIOSes, which never happened. I even went to the lengths of contacting Intel to verify that patches had been generated for the Z68 chipsets and that they had been sent to Gigabyte, which Intel confirmed. Basically, Gigabyte got the code and simply decided not to patch the exploits on older chipsets despite saying they would. In any case, poking around about getting NVMe working on z77x-UD5H and UP5 boards led me to discovering the possibility of patching the BIOS. It leaves me wondering if anyone has patched Z68 boards with newer BIOSes as it regards meltdown and spectre.

Thoughts?

Thanks!

Unfortunately, no.

@mutatio I have the GA-Z77X-UD5H / i7-3770K combo. Using the latest official BIOS, has got the NVMe booting in the PCIe X4 slot (shows up as an internal drive). My cheap PCIex1 adapter card is bottlenecking it at the moment. More here: https://www.tonymacx86.com/threads/...geforce-gtx-660-ti.70530/page-59#post-2073650

I prepared two BIOS: One for GA-Z77X-UP4-TH (for work with sabrent pro 500GiB + ugreen PCIe 4.0 adapter) and another with your GA-Z77X-UD3H.
I could test the first one and works flawlessly, the other one will be tested as soon I receive a new set of sabrent pro 500GiB + ugreen PCIe 4.0 adapter. If you're interested I can guide youto achive a BIOS for your mobo.

I wanted to share how I was able to get my Z77 system (Gigabyte GA‑Z77X‑UP5 TH motherboard) to successfully boot off of a Samsung 950 Pro NVMe SSD using a PCI Express adapter. I know there are several others using this same motherboard for their builds, so hopefully someone will find this information useful. The BIOS on this board doesn't have built-in support for NVMe devices, but I was able to use the AMI MMtool to extract the NVMe modules from a Z97 BIOS (GA-Z97X-UD7 TH) and insert them into the latest (F12) BIOS for the GA‑Z77X‑UP5 TH. With the modified BIOS installed, the Samsung 950 successfully shows up as a boot device in the BIOS (see the screenshots). With RehabMan's HackrNVMeFamily-10_11_6.kext and via Clover UEFI, I am currently booting off the 950 without any issues. Note that for UEFI booting, the 950 shows in the bios as simply "UEFI: Hard Drive". I've attached my modified BIOS to this post in the hope that others will find it useful. Please let me know if you have any questions or would like clarification on any of this.

The adapter and NVMe SSD I am using:
Ableconn PEXM2-SSD M.2 NGFF PCIe SSD to PCI Express 3.0 x4 Host Adapter Card
Samsung 950 PRO Series - 512GB PCIe NVMe

NVMe patching script by RehabMan:

Modified GA‑Z77X‑UP5 TH F12 BIOS attached


I have the identical motherboard and have loaded the modded BIOS F12 but my NVMe SSD is not showing up. No UEFI Hard Drive is in the new BIOS. Is there a reason why the modded BIOS is not seeing the NVMe SSD PCie with PCIE in the suggested slot location?
