14'' HP 8460p HD6470M + GTX750Ti@4Gbps-EC2 (PE4C 3.0) + Win7 [purpletoast]


Recommended Posts

Going to write a thorough guide. Will edit when i have time.

 

 

System:

Hp Elitebook 8460p

Windows 7 x64  Professional

No internal gpu (igpu)

Dedicated gpu (dgpu) AMD Radeon HD 6470m (new driver update lists as AMD Radeon HD 7400m)

Chipset Intel QM67, Bios: 68SCF ver. F.61 6/112015

8 Gb Ram

 

 

Setup:

EVGA GTX 750ti SC

PE4C v3.0 (EC)

Power supply (model #) - note - make sure your atx power supply link has enough amps & watts for your chosen graphics card

External Monitor

 

Todo:

DSDT override - Aida64 Engineer Edition (Free Trial) - any other method of DSDT extraction gave me a corrupted DSDT file

note - did not try usb boot linux

Update BIOS, chipset drivers (recommended)

Setup 1.30 - note - Any PCI compaction except dgpu only/egpu & egpu only disables the keyboard (I think, need to recheck)

Setup:

Note - A case for the pe4c v3.0 set up is recommended

Note: I've been pretty busy lately. If you have this notebook model feel free to ask me questions.

Something makes me think you probably enjoy coffee candy. :)

 

Haha, yeah. Coffee candy, coffee (black), espresso, cappuccino, tea candy, tea, etc. Anything with some amount of caffeine.

 

By the way, my name's Brian also.

Thanks a lot 'Idol' for your reply. Hope all those coding pays off :( ....

Can you just let me know if i need to buy the 1.3 setup as well or my laptop should be good without it.

Also is the process safe? i mean i am a developer but have no clue about those steps at all - is there a recovery process in case i mess up my beloved laptop?:) 

 

Regards,

Somik

@Somik 

 

regarding the setup 1.3 in my case i tried EVERYTHING but couldnt manage without the setup 1.3 (which rewrites de PCI allocation), so my advice dont go crazy and go for the setup 1.3, @Tech Inferno Fan its selling it here for the forum members, and you will feel great contributing for such and AMAZING job he did :)

 

 

 

Regarding the ASML mod, just a regsitry backup will be enough but its more likely it doesnt compile or does anything (if you dont follow the steps PRECISELY) that breaks anything, dont worry, check the FAQS for the compiler error debugging, its imposible without it.

Hi Idol,

Fresh Windows 10.

Stuck at "code 12".

Did you manage to solve it with Setup 1.x?

thanks"

Thanks.

Do you have the EC slot switched to Gen2?

I have lots of micro-freezes when on Gen2. Fine on EC Gen1.

Even when on Gen2 I only have Bus Interface at x1 1.1 in gpu-z

I am working on an almost identical set up (my GPU is only a GTX750) I have followed the instructions and I can not get the bios to boot, it just goes back to the selection screen windows 10, Restore, DIY eGPU setup 1.30

I didn't see anything in the html instructions about DSDT ...is this something I should do before the setup?

 

@Tech Inferno Fan the links don't work on the implantation Hub
