Gigabyte Z77X-UD3H (revision 1) - adding NVME support for Samsung 950 Pro.

BIOS/UEFI Modding Reports: BIOS Modding Results
1

I wanted to post this to save anyone else the headache I went though to get the 950 pro to work.

I followed the tutorial on overclock - here and also tried the one - here without any luck.

No matter what, I kept getting the “File Size Exceeds the Volume Size” message which was super annoying. With some googling I found this. Don’t delete the mouse driver as mentioned, for whatever reason you can’t (or I couldn’t) get into the advanced bios as described.

Instead I followed the information from the last post and deleted:
NetworkStackSetupScreen
DcpDxe
ArpDxe
SnpDxe
MnpDxe

I then went back to the overclock tutorial method and inserted the three nvme modules as described (Nvme, NvmeSmm, NvmeInt13). This worked fine, I flashed the BIOS using the gigabyte @BIOS utility and restarted with a working NVME drive.

For the Z77X-UD3H - I used the F18 bios from Gigabyte.

The bios I took the modules from was the F9 from Gigabyte.

As to results of the drive, running on the 4xPCIe (v2) slot, I’m getting approx 1500 read and 900 write.

Hi, I have the same mobo and I am considering using a Intel 600p. Thanks for posting this info, I have some questions.

First, from what BIOS did you did you extract the 3 NVMe modules you listed ? (You only mentioned F9… Was it the Z97X-UD3H ?)

Also, why those 3 modules instead of the module in this guide ? Was it bigger ?

Thanks !

@kheltar :
Welcome at Win-RAID Forum and thanks for your report!
I am sorry for the delay, but I obviously missed your contribution in February this year.

Welcome at Win-RAID Forum!

You should consider, that the user kheltar had written his post already in February.
According to my own experience it doesn’t make any difference regarding its functionality whether you insert
a) the 3 different NVMe modules taken from another BIOS or
b) the single NVME module named NVMeExpressDxE, which you can find within >this< guide.
Since the 3 NVMe modules all together need more space within the BIOS than the single one, I would prefer the latter. Furthermore you can avoid this way to remove more modules than needed from the original BIOS (to get the required free space).

Good luck!
