DIY eGPU experiences

[kizwan]

Strangely enough, installing windows 7 64 did solve the problem! The graphics card was recognised straightaway and it worked like a charm! Thank you, kizwan.

However, Laptop 1 suffers from black screens (both of them) if I chainload to windows without PCI compaction (although I still can hear the boot up sound it's just the screen is black). Any thoughts?

Vista doesn't support two graphic cards from different vendor. That's why Win 7 is recommended for eGPU.

I don't know what's wrong with Laptop 1. Please try boot without eGPU, do PCI compaction & chainload. This is to see whether PCI compaction worked OK or not on your notebook.

I've been following this thread for a while and am looking forward to the ExpressCard version of PE4H 3.0. I have a HP Probook 4530s which from what I have read elsewhere is a perfect candidate for an eGPU.
My question is: Does anyone know when v3.0 of PE4H is set to get released?

Just a small OT:
For anyone in Europe interested in the purchase of a PE4L 1.5 (with both EC2C and PM3N, EC2C adapter, SWEX and the power cable), i'm planning to sell it.

How much do you plan to sell it?

I asked the same on their facebook

"PCIe Gen2 version of PE4H (v3.0) is now under developping.
The engineeering sample was fine, so now we are now developping another version for mass production.
We hope we can release in May."

Can you spot me the link to their facebook? Thanks

I'd say 45€ + Shipping (depends on where you're located)
For further info, send me a PM.

At the beginning of the file, there are two lines of these:-

ACPI Warning: NsLookup: Type mismatch on BFWB (RegionField), searching for (Buffer) (20091214/nsaccess-731)
ACPI Warning: NsLookup: Type mismatch on BFWB (RegionField), searching for (Buffer) (20091214/nsaccess-731)

Removed them.

You forgot to close the QWordMemory code with ")".

				//ADDED FOR 36BIT space eGPU
				QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
					0x0000000000000000, // Granularity

					,, , AddressRangeMemory, TypeStatic)

Other fixed you need to do are:-

1. Correct the reserved name. iasl.exe compiler doesn't allow "Name" with underscore character (_) in the name. So, find this:-
   

   Name (_IRC, 0x00)

   and changed it to:-
   

   Name (IRC, 0x00)

   This usually followed by finding all occurrence of "_IRC" in the file & change them to "IRC" too. Fortunately, in your DSDT there is no other occurrence of "_IRC" in the file.
2. Find all occurrence of:-
   

   Name (_PLD, Buffer (0x10)

   and changed them to:-
   

   Name (_PLD, Package (0x10)

Before you try this DSDT override, you should try boot with eGPU connected first. "boot with eGPU connected first" means from OFF state, connect eGPU to notebook, power ON eGPU, power ON notebook & see whether it can boot straight into windows or not.

ATI/AMD graphic card required 256MB of contiguous 32-bit PCI space. The keyword here is "contiguous". Nvidia Fermi graphic card required 128MB+64MB+32MB BAR. This means it needs 128MB of contiguous PCI space + 64MB of contiguous PCI space + 32MB of contiguous PCI space. Older Nvidia graphic card, like GTX280 required 256MB+32MB+16MB BAR.

If you get Error Code 12 even with low TOLUD, it only means there is no sufficient contiguous PCI space for eGPU. This is where PCI compaction come to play by shifting other devices to create enough space for eGPU. You also can moved Intel HD to 36-bit space (will need DSDT override) & this will freeing 256MB of contiguous 32-bit PCI space for eGPU.

Can you please help me with my .dsl? I just keep getting parse error expecting '$' and I couldn't figure out how to fix it

Hello everybody,
I Boughta pe4h with EC2C and a EVGA GTX460. I Have a Sony Vaio VPCEB23FM with 8GB Ram and intel i5 460m, External Monitor works fine without trouble, but I just can't use the x1.1opt. I tried DSDT and setup 1.x getting just negative results. can somebody tell me what else i should try?

Can you please help me with my .dsl? I just keep getting parse error expecting '$' and I couldn't figure out how to fix it

To get the Optimus to engaged on internal LCD, make sure eGPU is connected before windows loading. Please make sure you have "preferred graphics" option in Nvidia control panel.
