I thick it's the problem is not about the bios but the adapter and the pic-e x4 slot.Try the clean the golden finger with an eraser and clean the pic-e x4 slot with little broom.

If it is so,I suggest you try to flash it back to legacy bios.And try to boot the system with other disk to open the crystaldiskinfo,to have a look with the nvme SDD.

I've switched to o/b graphics and put the m.2 to the x16 slot, yes now it has capability of pcie 2.0 x4. My standstill Raid0 config is same as the speeds, so no need to back to legacy bios.

Anyways, with my mobo which has a standart capability of pcie 2.0 this is the max results i think.

Los_N_BIOS you are such a nice person , helped with all these...

@yabay - Thank you too! It's good you got it working properly now, but this means you loose your good graphics card use correct?

@gloobox - good tip, I didn't think to clean or reinsert, sometimes that does fix lane width issues - best to check that yabay!

@Lotst_N_BIOS , I've sent a message to GIGABYTE offical e-support and they replied. They sent me an upgrade from U1A bios to U1C, There the post screen logo changed and also some improvement in the menu selections but, the seconds X16 lane speed remains as X1.. I reported the remaining problem, see if they can make anything.

Dear Yabay

Thanks for your reply.

BIOS U1c is the latest version we had. Due to this is old model, we would not update new BIOS. In addition, this motherboard doesn't support Windows 10.

Sorry for the inconveniences.

Best Regards,

GIGABYTE


I will give a try with win7 if it makes any better than 1000Mb/S, But again i need your help integration the nvme module to the new bios.

The new bios file is below:

PC: we have a good database for GA-Z68PDS3, so maybe it can be useful to the other users if the moded and uefi files added to the bios download list in the forum?

Dear @Lotst_N_BIOS, i succesfully inserted nvme module to the new bios and can see my m.2 in the UEFI section so, for you there is no need to be work on that. According to gigabyte's message,i'll give a try with WIN7 64Bit asap

ps: As its worked proper (same speed with my Raid0 config) there is no need to replace the good GFX card and use m.2 in the cards lane. So i'll try with win7 if there is a major change.

Great you got new BIOS and were able to modify it already too @yabay

link speed x2, isn't that better now than before? I didn't look back, but thought it was stuck at x1 before correct?

Thanks for adding BIOS file for others, adds to my pile too

Link speed didnt improoved, still shows X1 in WIN10 , i will tell if any change under WIN7..

For the forum

GA-Z68P-DS3.U1C UEFI FILE (WITHOUT NVMe MODULE):

GA-Z68P-DS3M.U1C UEFI FILE (WITH NVMe SUPPORT):

Ohh, I saw x2 in second image above (now removed?)

From the gigabyte, as its stated, This UEFI BIOS not compatible with win10, then i installed WIN7 64bit again if it make any change? frustration

The 2. pci lane remains the X1 speed. I reported this to gigabyte e-support againg :) war continues

I see now, it was your image in post #34 I saw 2 but it was speed, sorry I confused that and though it was link width, I see it correctly now that I look again.

Hopefully they will take the time to test and fix this for you!

They answered..


Dear Yabay

Thanks for your reply.

It seems that UEFI BIOS couldn't support well on this motherboard. Due to this is old model, we would not update new BIOS.

In addition, we suggest you install Intel chipset driver from Intel website and M.2 driver from M.2 drive website.

Sorry for the inconveniences.

Best Regards,

GIGABYTE

Maybe those drivers will help?? Doubt it, but worth checking out. Or maybe go back to legacy BIOS type and ask for help to get Clover setup properly

I checked to update drivers few times, all are up to date.

May be best then to go back to Legacy BIOS type, if you want the faster speeds. It worked much better then correct?

very strange
i take the u1a bios，but after using the flashefi to flash it, it failed~~~
turned into black screen………………

Did you use the discrete graphics card?
I found I only can launch it with the integrated graphics card^

Btw,I am interested with the software "PCI devices" you post in the pic,where to download ?
