HP pavillion dv7, SP51315, vbios FIX 9600m (tested).

[synosx]

hi , for anyone using the SP51315 bios for his, dv7. and has a hard time with the 9600M GT gpu

i downloaded the modded unlocked bios made by Camiloml.
and changed the vbios of the 9600m, i am now able to download latest updates of drivers from NVIDIA , no longer stuck with the old drivers, i was able to install windows 8.1 with latest drivers no problem.

what i did,
1- changed the vbios in the SP51315 (already unlocked by Camiloml), with one vbios from techpowerup website
2- removed 4th voltage step from voltage table, kept the v0.9 instead of v0.89 (no issues appeared at all)
3- added timings from the original vbios
4- followed NightWalker method for clockrates, (no overclock just copy paste highest clockrates to 2nd 3rd step, left 1st step unchanged)
5- MXM countdown is set to 1 second ( i don't know how to remove it. )

benchmark before new vbios was ~180, current is ~410 (using gpu tester benchmark).

i tested it on dv7-1285dx.

only flash this if gpu is problematic when using latest drivers, or you tried windows 8 and couldn't install gpu. if not then use the Camiloml bios.

i am not responsible for any damage you done to your laptop

to install, remove all .FD files from sp51315 folder, extract my file inside the folder, run winflash.bat
