purpletoast Posted January 12, 2016 Share Posted January 12, 2016 (edited) 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!

Dsdt override! 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: Quote 9. The same fix was done on a Dell E4300 and Win7 did automatically allocate the eGPU into the 36-bit space. If you still see error 12 then there are two options to pursue: Re plug'n'play the devices. Go into Device Manager -> Video cards, delete the eGPU. Also go into Device Manager -> System devices and delete the PCI Express Root Port x entries. Upon restarting the system, halt Win7 startup with F8, attach and power on your eGPU and then proceed to load Win7. Win7 should now be clever enough to re-allocate the eGPU into 36-bit space upon realizing there is insufficient 32-bit space to host it. Can go one step further and delete your eGPU NVidia/ATiAMD driver, restart the system and reload it. That may help as well. Hard allocate the eGPU into 36-bit PCI space before booting Win7 using Setup 1.30. Select PCI compaction->Endpoint=56.25GB (36-bit) and then select Run compact. When prompted for the scope select eGPU. The result will be similar to that shown in the spoiler in step 8 above, but with the eGPU rather then the Intel HD iGPU being in 36-bit PCI space. Can then proceed to automate this by editting your %DRV%:\config\startup.bat (or V:\config\startup.bat in windows) so can just select the Automated startup via startup.bat Setup 1.30 bootitem and have it do everything for you: call speedup lbacache call vidwait 300 call vidinit -d %eGPU% call pci call chainload mbr Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

aldimeola81 Posted January 14, 2016 Share Posted January 14, 2016 sorry if I insist but about the compatibility and plug and play egpu install what is better: a PC with only intel iGPU or iGPU + dgpu? thanks. If are confident of doing a DSDT override then the T530 iGPU model would be the preferred option. Usually less costly than the dGPU model. arteart successfully applied a DSDT override on a iGPU-only T430 at https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12/ which then gives a plug'n'play solution. The t530 is arrived, I have reinstalled windows 7 with egpu connected, no error, everything appear to be fine, the igpu and egpu are installed without problem.. But when I play with games they use only the igpu, I've tried selecting the gtx960 inside nvidia panel as preferred for gaming but no changes. Any advice? I must install egpu setup for make it work? Thanks. Inviato dal mio Lenovo P70-A utilizzando Tapatalk Edit: solved ! After connected an external monitor the egpu works also into internal over games, t530 works without any mods.

pants_problems Posted January 15, 2016 Share Posted January 15, 2016 (edited) I've been successful in running a GTX 970 Zotac on my Late 2013 iMac for the last few months, namely in Windows 10. On some games though, I receive some horrendous stutter and I cannot for the life of me narrow down where it's coming from. Also, some games seem to perform better on my 780m. I've tried adjusting the settings I can think of, but none of them seem to help. Additionally, I have a Thunderbolt SSD attached to the 2nd port of the Thunder2... does that affect performance even if the drive itself? Either way, I just want to get rid of the stutter. My setup: Akitio Thunder2 => Powered PCIe Riser => Right angle adapter => 970GTX (in a Cooler Master 130).

VintER! Posted January 15, 2016 Share Posted January 15, 2016 Hi guys, I got problem with my eGPU and i'm very disappointed. !! seriously need help !! First time i tried to run eGPU i was getting blank screen, then i solve it buy disabling Network PXE Boot, and setting BIOS Graphic Device to UMA. Then i started getting problem that my laptop is not recognizing the eGPU and it shows it in Device Manager as "Microsoft Basic Display adapter " ( Eror Code 31 ). I have tried to unplug my eGPU but the screen start stuttering then shut down. I really don't know what to do !! i've been searching for solving this problem for months didn't find answer. PLEASE HELP My Setup specs : eGPU : GTX 750ti iGPU : Intel HD Graphics 4000 dGPU : GT 710M Laptop : Lenovo G580 Adapter : EXP GDC v8.0 mPCI version PSU : Gigabyte GreenMax 650W Plus OS: Windows 10 - 1 Link to comment Share on other sites More sharing options...

Reading your other posts I saw that your laptopis the L502x, correct? If I am not mistaken according to your laptop's schematics your laptop should probably be able to get an x2.2 connection combining port 1 (WWAN) and port 2 (WLAN). Can you try to locate your SDATA-OUT (or SDOUT) signal in order to unlock flash descriptor? EDIT: It is on page 38 pin 5 on your ALC665 chip. I think that my guide takes it from here. Do you have the available hardware to do the x2.2 connection? AFAIK the PE4C v3.0 doesn't offer an second connection as the v2.1 did.

theepicarrow Posted January 22, 2016 Share Posted January 22, 2016 Hi everyone, just a quick update on my situation. I've tried setting a delay, which now allows my laptop to boot with the EGPU connected, however this still gives me an error 43. Reinstalling the drivers several times does not seem to work either. I've now even tried to use an older driver. Can anyone offer any suggestions as to what I should do next? I'm all out of options. Link to comment Share on other sites More sharing options...

Also I'm unable to start NVIDIA control panel or any games without them crashing. I tried running DDU to uninstall my quadro card drivers before installing these drivers but still no luck.

I figured since your laptop is the most similar to mine, you can perhaps hopefully help me with my eGPU troubles! From what I understand Setup 1.3 has very little success working in UEFI mode. Since I am using that currently, would that mean I would need to follow what nando's instructions in order to get it working under the legacy BIOS? (I'm asking this because I don't know if the older generation of the Elitebooks came with a legacy BIOS and I'm curious to know if you got it working under HP's UEFI or using a legacy BIOS) I'd really appreciate if you may help me with this before I go ahead and purchase setup 1.3. I've got a GTX 660 and PE4C 2.1 for a setup ready, and I've already performed a DSDT override, now I just need this part of the puzzle to complete it Link to comment Share on other sites More sharing options...
aldimeola81 Posted January 31, 2016 Share Posted January 31, 2016 I have a partial success connecting t530 igpu only with PE4C and MSI GTX960 4GB: win7 64: internal monitor is working and external too, wei give the max to graphic ; the benchmark of fire strike rate the system around 6000 and over 3dmark 06 21800, the card must be connected at startup and the external monitor must be connected after boot otherwise the PC freeze on boot. No need of use egpu program , only driver install, very good performance over real games on fhd monitor into new games as gta5, fallout 4, crysis 3.. High or ultra details, work stably for hours, the laptop remains cool and the GPU too even overclocked. BIG Thanks to Nando4, and his big patience.. The problems remained is that I have to disconnect every time the external monitor on boot and to make it work over Ubuntu..
