DIY eGPU experiences

[pappu6600]

After following below procedure msg appears as gathering system information there after Menu screen reappear but it doesnt show any information about eGPU detection.

Note: Couple of days ago i added 2 GB RAM total 3GB RAM does this have any impact on this.

Thanks.

Please try:-
# At "PCIe Ports" menu, set x2 link on Port1
# Power ON eGPU.
# Press F5

Let me know whether eGPU is detected or not.

I'm assuming you're using ATI HD5750, am I right? Did you connect the floppy power connector to PE4H? Please post the PSU specification.

Is this your eGPU connection?
- PE4H's PCIe port x1 connected with EC2C (PCIe Port2)
- PE4H's PCIe port x2 connected with PM3N (PCIe Port1)

eGPU connection is right.I am using ATI HD 6570 2 Gb.I have connected floppy power connector to PE4H.PSU details ATX P4 Switching power supply model P4-350. On PSU wire details are 10A 250V-AC.

Thanks.

What is the maximum current on the +12V? ATI HD 6570 power requirement is 44W. Does LED on the PM3N card light up?

[pappu6600]

At +12V v output 18A, MAX 216W
I also tried to change the ports like connecting EC2C on port1 and PM3N at port 2 that time in device manager-display I saw Ati HD 6570 device with yellow explaination mark then I install driver for Ati HD 6570 and after reboot I found that yellow explaination mark as it is.

Note: After clicking on yellow mark (Properties I saw some code 12 error)

Thanks.

You'll need to give detail information. For example what is the error code in the device manager?

Do you mean with these connections, eGPU is detected?
- PE4H's PCIe port x1 connected with PM3N (PCIe Port1)
- PE4H's PCIe port x2 connected with EC2C (PCIe Port2)

If yes & eGPU detected, that is good news. You'll need to let us know what is the error code in device manager.

Are you using the PSU to supply power to the PE4H as well? 12V*18A=216W which should be plenty for a 560 Ti and the PE4H, although you might be limited as far as overclocking is concerned.

Yes. And i don't intend to oc since my GTX 560 ti is already factory overclocked. Besides Ocing does not seem to impact noticeably the perf on egpu.

To solve error 12, you'll need to do PCI compaction using Setup 1.x.

For the moment i've been able to play BBC2, Dead Island and Deus ex HR smoothly on my internal LCD at 1600*900. Amazing. I'm not really looking into the external LCD way for the moment.
Though i had a quick try on someone' LCD TV and it worked great on HDMI. Optimus doesn't like adapters. HDMI to DVI and DVI to VGA = Fail

First of all, I recommend getting PE4H-EC2C ver2.4 directly from HWtools.

ATI HD6790¹ power requirement: 150W
ATI HD6870¹ power requirement: up to 200W on peak 3D & overclock
¹ Both require two 75W 6-pin PCIe power connectors

I don't know ^^the PSU specification but make sure it have enough +12V power. The PSU must have at least 18A current on the +12V rail (+12V@18A=216W) for ATI HD6870.

ATI HD6870 is faster than ATI HD6790.

Performance on x1 link is not very good. For best performance, at least x2 link is recommended. For x2 link² setup, you'll require PE4H + EC2C + PM3N or PE4H + PM3N + PM3N kit.
² x2 link setup required PCIe port 1&2 or 3&4 or 5&6.

Please check using AIDA64 for PCIe ports assignment. You also need to check on the notebook to know whether the mPCIe port(s) is/are available physically or not (tip: open the HDD/memory/wifi compartment).

According to VGN-CR35G : CR Series : VAIO Notebook : Sony Asia Pacific , your notebook have ExpressCard 34.

i didn't understand the x2 link setup! the EC2C goes into the expresscard 34!
so where does the PM3N goes?inside the laptop?replacing it with the wifi adapter?
