Hi,

I am trying to do the DSDT override on my w530 running on windows 7, and after following everything until step 12, when I restart the computer, I get a BSOD while windows loads. The way i can get windows to boot again is to do a system restore. Is there anything that needs to be done differently or is the W530 incompatible?

thanks

EDIT: could be it be due to an error or warnings I keep getting when i try to compile?

I tried to compile immediately after step 3 and i get the same error/warnings.

Hey I was wondering if you ever got the error 4103 figured out? I am having the exact same error on my X230 with a 750 ti.

[ArneFW]

After going through your entire DSDT override process, I don' have a Large Memory section in my Device Manager. How can I fix this?

As you are using Win8, ensure you have testsigning enabled with 'bcdedit -set TESTSIGNING ON' otherwise the registry override will be ignored. If still no go, then suggest working methodically through http://forum.techinferno.com/diy-e-gpu-projects/7476-%5Bguide%5D-dsdt-override-fix-error-12-a.html#post102517

I have enabled test signing, and still no Large Memory. Or do I have to go through the entire process again now?

[ArneFW]

When I run iasl dsdtoverride.dsl , it doesn't create an .aml file. Why is this? I think that is the problem

[ArneFW]

When I get to the step where an AML file is supposed to be created none is. Here are some screens of my command prompt to ensure I am doing it right.

same here. 9 errors and warning. when i reboot there is no large memory in device manager!!!

[TheDeathEffect]

I think you need to fix all of the errors before it will compile. In the DSDT Editor, after you go IASL > Compile, a popup will show how it went. If there are errors, the "Fix Errors" button should take care of most of them. You'll have to go back and fix any errors that it didn't.

[Kokzreh]

Hello,

after having tried to rewrite my dsdt.dsl according to the tutorial for an hour, so that I can finally use my eGPU, I now stopped due to exasperation.

Would one of you be so kind as to help me and rewrite the dsdt for me? Help would be very much appreciated and I’d also buy you a beer.

Hello, another noob here ... I can not understand this guide for weeks and I can not make my EGPU working. really what file or program I have to run? I instal all the programs and tools from this forum! can someone help me please? I am close to give up the project and lose € 200 already spent with this!

clear that the product company (EXP BEAST) does not give suport and spend all their time asking for photos and videos and do nothing.

(Samsung RV520) thank you

UPDATE: i make all the steps off the guide but steel have error12/code12

[Chrishnaw]

For the life of me I can't get this to work and I need your help.

I've followed all your instructions verbatim but I get an error at step 12: "asl /loadtable dsdt.aml"

http://i.imgur.com/cQDUb5s.png

I've searched for "Count not access the registry path:" and a dozen other clues or hints on this forum and Google but haven't found anything useful.

My laptop is a Dell Latitude E4310 (same as the one Nando4 used to test his DSDT override):

Intel 5-series chipset, QS57 motherboard

Core i5-560M

Win7 Pro, SP1

[misterblacjack]

The only way I can see large memory is in testing mode, that's it I tried doing it in normal but still no luck any help?

I had the same problem. You have to run CMD with admin rights. Go to search and type cmd, right click it and select "run as administrator". That should solve that issue.

The only way I can see large memory is in testing mode, that's it I tried doing it in normal but still no luck any help?

Are you running Win 8 / 8.1? If so right after you type asl /loadtable dsdt.aml and it successfully completes type bcdedit -set TESTSIGNING ON and that might solve your problems.

All these steps are found on this guide. Just read it thoroughly and it should help you out should you run into more problems.

[Draxler]

hello guys,

i could not be succesfull at step 9 and after steps. please help me about these steps.

i dont know to use command page(black window) so i need to help to complete for steps 9-10-11-12 and others.

maybe you can share print screen or video or another help. Thanks

Hello,

I can't run DSDT editor, i tried everything, when i run it a CMD window flashes and disappears straight, i google that issue without success. Any ideas?

Have the same problem, I think we are going in the wrong direction somehow.Hopefully someone will reply

[Yomommassis]

I'm confused, so does having the iGPU, dGPU, and eGPU all enabled at the same time have any advantage if the eGPU performance suffers?

This I'm not sure. Make sure you have Java installed? IIRC the editor runs on Java. Apart from that no idea.

I'm confused, so does having the iGPU, dGPU, and eGPU all enabled at the same time have any advantage if the eGPU performance suffers?

Not so much, a bit with PhysX things if your dGPU is pretty decent. But it is better to just have iGPU + eGPU.

[angerthosenear]

Closing thread since I can no longer adequately provide good support.

Things have changed in the 2 yrs since I put this up. This is mostly old information now, useful for those still running Windows 7.

iGPU + dGPU + eGPU isn't worth it in most cases, so just stick to iGPU + eGPU which you can find other threads about.

Good luck with eGPU goodness!
