Unlocked A14 BIOS with:

- GPU OC 1058 mhz (boost)
- VRAM OC 2230 mhz

With this mod we have clock speeds equal to GT 750 m (that installed in XPS 9530) and keeping all of quadro’s features! In 3DMark Night Raid our Graphics score increased from 4854 to 7334 points (51% improvement)

If you have issues, related to vram/gpu OC, you can edit Quadro’s VBIOS by yourself. Just search in UEFITool this GUID - E4D65F56-A551-4F74-BDC4-C6EFFF0F993B , extract body, and you have it. To edit your vbios use Kepler Bios Tweaker. Don`t forget to replace vbios in bios file.

Can you provide the modified file with the OC attached? Ty!

Hello, just signed up after finding this on google. Has anyone here tried it?

I have the same laptop here with A14 BIOS, i7-4712hq CPU and Quadro k1100m GPU, it also has a 4k touchscreen, would this bios be compatible?
Are there any how-to’s around on the forums i could read thru? The performance increase would be worth the risk for me as it cost me very little and i have another laptop incase things go t*ts up.

Thanks!

edit just used Universal BIOS Backup ToolKit to backup my BIOS and its only 2mb in size?? The A14mod posted here is 6mb. I think i have a lot of reading to do before attempting this lol.
