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.

 

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

 

 

Will add: benchmark & video of graphics card in action

 

 

 

 

 

 

 

 

 

 

 

 

 

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

Would be more helpful to create a complete 8460P implementation guide where the DSDT part has a link to the fixed DSDT. Then 8460P users have a complete reference of what they can get going after putting in the required steps.

 

Sounds good! When I get it working, I'll make a guide on what I did/Steps I followed.

https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12 already explains next steps to do if you still see an error 12 after performing the DSDT override. Quoted here in case you missed it:

 

 

 

Ah, seems like I missed part 9.b . I'll retry step 9.a and update later tonight. Also, would uploading the fixed dsdt with the relevant laptop model number/bios version be helpful, or will it just cause people more problems.

Hey everyone,

 

I got my parts in yesterday and I've spent many hours tinkering with it. (HP Elitebook 8460p)

 

After doing some troubleshooting and patching (Nothing worked to get me a clean dsdt except for Aida 64 version: Engineer [free trial]) I successfully completed the dsdt override!

 

Sidenote: was too lazy to make a Linux usb drive, thanks nando for the guide

 

Now, I'm wondering if DIY Egpu setup 1.3 is the next step if i'm using:

-  a Series 6 chipset (QM67) - EC x1 2.0 (Pe4c v3.0 EC)

-  have the large memory space

-  > 4 gb ram;  (8gb ram)

-  AMD dGpu (no iGpu), an eGPU nvidia gtx 750ti card

-  most importantly: all the load options I tried are allocating small bus resources to the eGPU in the EC slot (Code: 12).

 

There's not a lot of information since I can't access the later pages of the thread due to some error.

It seemed like the right one due to the PCI compaction, changing PCI busses, and disabling the dGpu. I wanted to make sure before purchasing that this is the logical next step.

 

Dsdt override!
