Kaby Lake BIOS updates P775DM3-G & P751DM2-G

Wait that happened only with the update you flashed?
They where working before?

 

Notebook was brand new and I never got ot test the GPUs before flashing. I used a Skylake chip to flash he new bios and after in dropped in the Kaby Lake chip. After that I installed windows and could not get the second GPU to work. After swapping the GPUs between them I got that screen anomaly with is fixed if I swap back the GPUs in their original position. My guess is that the slave GPU is dead.
Do you have any other suggestions? I mean from how this GPU is behaving I think it's a hardware fault since it's showing that screen all the way from bios to Windows.

 

Does the defective GPU show a vBIOS revision in GPU-Z?

 

Yes. It's visible in GPU-Z

 

What vBIOS versions are showing for the non-working slave as well as the working master GPU?

 

I already packed the notebook for a return. Do you believe that there might be a chance this could be resolved with a bios update?

 

Also I need to point out that the image corruption also happens during BIOS POST so I don't think it's driver related.

 

If you tried without SLI cable and only the 'broken' GPU on it's own, then it is probably a hardware problem.
BUT, if they mixed a g-sync and a non g-sync model GPU or different vBIOS and it was always connected via SLI then that may cause problems.

 

Ok. I can try again and maybe revive them. I remember from dissasembly that the stickers on the GPUs where it says the VB and model number where the same on both GPUs.

Should I try to flash new BIOS on both cards?

 

Na, if they are same just RMA it.

 

Ok. Thanks for the help anyway.

 

Thanks, works like a charm for me. However, shouldn't you run restore.nsh in the end instead of eol.nsh like the readme says? It runs eol.nsh plus some other stuff and the only other update manual I found (XMG's) mentions it instead of el.nsh.

 

I can only go by the instructions I was sent.

Can you link me to the XMG instructions?

XMG_U717 -> KBL_Update_U717.zip -> Instructions BIOS-flash_SKL-KBL.pdf

 

If you look at what's in the 'restore.nsh' file it doesn't appear to do anything other than run the 'eol.nsh' as none of the other .nsh files exist in the folder that comes with the XMG BIOS. As to the ones that come with the BIOS Clevo supplied the 'Update1,2 & 3.nsh' files just write a serial to the system, but none of the files have a serial number in them.
I suppose Prema might now if they actually do anything, but as I got my instructions from Clevo and have updated 7 laptops so far I'm not going to change the way I do it.

 

well, there goes my P775DM3, flashed the XMG one cause i have one and seems like the last step, after i run restore.nsh no post anymore

 

@Adbear: Going through the .nsh files again, I think you are right.

 

One thing I have learned in my 12 years with Clevo, never flash their stock updates without verifying them first.
At times, they send out quiet some quirky things to re-seller...

 

Well I haven't tested the P750 BIOS, but both the P775 and P870 BIOS I posted worked fine for me, but then the chassis's I used came with stock BIOS's in the first place

 

tbh i thought that i was already tested and shipready from them, but yeah not always the case, any ideas i could try? CMOS didn't help so far, Fn+B and Fn+D didn't do anything either cause the usage of latter was even mentioned in the xmg instruction pdf.

 

Drop me a mail with the EC/BIOE/ME revisions currently on your system...

 

Has anyone been able to flash this on the Clevo P751DM2-G?

 

Update: I was able to flash the BIOS for the Schenker XMG U507 on the Clevo P751DM2-G by Origin.

No issues so far.
