DIY eGPU experiences

[fatpolomanjr]

Can someone help me with this please?

You get it when the PE4L ships, which could be up to a week. They send you a link to download Setup 1.x. Just make sure your Order Status is at least Confirmed, and you can be sure it will ship eventually.

Ok. I tried it but nothing changed, so I opened the aml file and tried to compile it (what shows errors in the DSDTEditor which I use) and there's an error in the 17th line. Here is the aml file:

Edit: strange situation - as I execute the aml file such an error occurs:

Can you look at it and tell me what's wrong?

You already successfully compiled the "minor changes" file to .AML file. Next step is to load the .AML file to registry using ASL.EXE tool:-

asl.exe /loadtable "400b2b 0.1.aml"

Look like iasl.exe compiler bug where when you decompiled the .AML file, it created two instance of "TNOT":-

DefinitionBlock ("Samsung 400b2b 0.2_.aml", "DSDT", 1, "SECCSD", "LH43STAR", 0x00000000)
{
    External (TNOT, MethodObj)    // 0 Arguments
    External (HNOT, MethodObj)    // 1 Arguments
    External (SNXD)
    External (HWID, IntObj)
    External (IDAB, MethodObj)    // 0 Arguments
    External (PDC7)
    External (PDC6)
    External (PDC5)
    External (PDC4)
    External (PDC3)
    External (PDC2)
    External (PDC1)
    External (PDC0)
    External (CFGD)
    External (\TNOT)

You just need to removed the second "TNOT". However, this is redundant. You already compiled the "minor changes" file to .AML file. Why do you want to decompile the .AML file & compile it again?

Hi Nando or Kizwan,

How do i save diags?
Do you mean saving all info from dxdiag?

Thanks

1. Boot into Setup 1.x
2. Connect eGPU
3. Press F5. Make sure eGPU is detected
4. Do 36-bit PCI compaction on eGPU
5. Run "!Save Diags" >> "Windows fails"
6. Chainload
7. In windows, run "V:\DEVCON\mkpcidmp.bat"
8. Zipped the V:\DIAG folder, upload it to somewhere (e.g. mediafire) & post the link here.

hey there, have a laptop- m6600 with quadro 5010m. Wanting to know if building a egpu setup to just add cuda performance for gpu rendering will work? (iray with 3ds max) Will the cuda cores from external gpu be combined with my inbuilt laptop gpu cuda cores? I understand that you don't get the full performance of the external gpu however, if it does work and combine, will I be loosing any performance from the external gpu if all I am using is cuda cores?
Thanks,
Chris.

Hi Kizwan,

The setup 1.x could probabbly solve the code 12 error but unfortunately im still the midst of obtaining the coupon code to purchase it.

Besides the DSDT override method are there any other methods that i could still try. From the FAQ i have tried almost all excepts those which requires setup 1.x

Thanks

Well yesterday I got an PM from some secret santa on how to set x2 on sandy bridge systems. It requires flashing an area called the "flash descriptor", which is located on the same chip as the system BIOS. Sadly, it appears that laptop manufacturers lock this region so that it cannot be rewritten after the laptop is shipped from the factory, so it seems that x2 and x4 are no go unless your manufacturer decided to ignore Intel's recommendation and not lock the flash descriptor. My flash descriptor wasn't even readable.

[kizwan]

How do you determine flash descriptor is not readable? I want to try read flash descriptor on Intel 5 series notebook. FYI, Intel 5 series chipset also use flash descriptor to set x2/x4 link.

Okay so I tried three methods of compaccion and none of them worked.

I keep getting Error 12.

You already successfully compiled the "minor changes" file to .AML file. Next step is to load the .AML file to registry using ASL.EXE tool:-

asl.exe /loadtable "400b2b 0.1.aml"

I loaded it (using a modified .bat file of yours: http://db.tt/EVLuvfqS) but still an error occurs (it's in this file: http://db.tt/vRiPCOG5). And also nothing changes in the Device Manager when I switch to "Resources by connection". Did I do something wrong?

egpu setup isnt free anymore? :/ great

It is a very complete and powerfull program. Developpers need help to continue this hard work.

You can get a 10USD coupon free. Just PM hitrc (nbr user) to get it.
