Right noted.

Got myself a DVI male to VGA female for a dollar off eBay, I'll see what I can do in a week or 2.

Lots of similar HP consumer SB/IVB notebooks sold. Thank you for this important post giving those owners a documented way of improving their GPU performance via a mPCIe-based (wifi) DIY eGPU implementation.

Are your benchmark results using the internal LCD or external LCD? External is faster since the display data isn't being shuttled across the x1 2.0 pci-e link for display back onto the internal LCD. The reference benchmarks on the main DIY eGPU experiences thread are using an external LCD.

Do you any photos of your experiment to share? Brings the whole thing to life

Benchmarks are internal LCD I'll try get that on some time after. My eGPU is dismantled atm because my desk is lacking space and I need it for something else. Noted that, I'll experiment with the external LCD (900p) when I'm ready. Got no idea on the performance level I'll be expecting. I'll be taking some pics too

Edit: I forgot that I lost my DVI cable a long time ago... Probably I'll try finding it.

Btw for best performance on an external monitor, simply plug in the DVI cable to the eGPU? Do I have to switch anything related to primary and secondary monitors via Windows display settings?

Wouldn't mind having a little help to take the ".txt" off the title. I brought it over from notepad.

• For users who want to reverse the order of the Windows bootloader to let the first option be Setup 1.x instead of Windows 7, use a tool like EasyBCD.
  
• The countdown timer can also be lengthened/shortened with this tool.
  
• It also looks like the PCI space requirement for the GTX650Ti Boost *could possibly* be following its bigger brother, GTX660 since it is an almost full featured GK106. Unlike the rest of the GTX650 series (650/650Ti non-boost). Installation encountered no issues at all.
  
• Tested only benchmarks and Crysis 2 so far. Crysis 2 was buttery smooth on extreme preset.

Type "device manager"

Drivers will install automatically.

What I used

• DIY eGPU Setup 1.x Software, version 1.30 (PM Nando4 to arrange a download)
  
  
• Port: HM67 mPCIe (Wi-Fi card removed)
  
  
• WLAN Card: If you need it, buy a USB one.

• Asus GTX 650 Ti Boost (OC Model) - No problems with PCI space, it should be same as GTX660 in this area.
  
  
• nVidia ForceWare 314.22 WHQL from nVidia (Not using the problematic R319)
  
  
• (Optional) Uninstall Microsoft Update KB2670838 and hide it permanently if you're BSODing from igdpmd64.sys (broken Windows update conflicting with Intel HD driver), your Internet explorer will rollback to IE9.

IMPORTANT: If your notebook has an AMD dGPU, DO NOT install a reference Intel HD driver from Intel's website stick with the stock Intel HD driver by HP. You have been warned...

Your AMD GPU (i.e. 6490M, 6470M, 6770M) will stop working without the presence of the factory Intel HD driver provided by HP whenever you need to unplug your eGPU. Reason's because hybrid graphics (Enduro) is not built into the AMD dGPU driver at least with the 6000M series. The implementation partially relies on a custom Intel HD driver supplied by HP.

You may only use Intel reference drivers if you have no AMD GPU. I'm stressing on this point.

Thanks, I'll look into that soon

So I've got all components ready. (eGPU in sig +PE4L)

Using Setup 1.x, I've been able to get my eGPU (GTX 650 Ti Boost) detected immediately. Driver installation was a success.

Here's what I've done so far as a first try

1. Installed setup 1.x
   
2. Connected eGPU via mPCIe
   
3. Turned off dGPU
   
4. Attempted PCI Compaction (iGPU eGPU)
   
5. Hot reset the PCI port for Nvidia
   
6. Chainload to Windows 7
   
7. Installed Intel HD 3000 3190WHQL driver.
   
8. Installed Nvidia driver 314.22 (for to avoid R319 that can potentially have issues)
   

Optimus works but I currently have the problems listed below:

1. When using the Chainload test run option, this message appeared

   WARNING: Some unallocated PCI devices exist as do not have pci valid alloc=yes. Recommend cancel. perform PCI compaction to get all devices allocated then proceed to chainload.

   
   
2. 3DMark Ice Storm score: Generic VGA video card benchmark result - Intel Core i5-2450M Processor,Hewlett-Packard 1794 Cloud Gate: Generic VGA video card benchmark result - Intel Core i5-2450M Processor,Hewlett-Packard 1794
   

Am I missing out something to get the eGPU working properly at the very least?

Btw, no encounters of error 12 or error 10 in device manager at all.

I haven't got the time to test things out further so far. Would appreciate if someone could help me with this issue.

It should do the job since you have 156W (12v x 13A) on your v2-rail alone. As you said: combine two molexes from v2 to 6-pin and you should be fine!

Thanks for the assurance!

I need help with this question, would appreciate some help here.

I got an ATX PSU from a friend's old PC. Its rated 300W on the box, 2 rails, no PCIe connector, has enough molexes to adapt it to 6 pin PCIe via 2 molex.

Its 12V rails are 12V1@10A, 12V2@13A respectively. Its made by Solytech. Are the specs of this PSU overrated? Does adapting the molexes give me enough amp to run a 134W TDP GTX 650 Ti Boost safely or do I need a better power supply?

Didn't know it was a non-issue. That's interesting.

At the same time, sorry for the unintended confusion.

Okay thanks thats good to know, so what do you recommend I end up buying since Ill need to take out my wifi card, PE4H or PE4L? whats the difference when it really comes down to it? Thanks

On this question, I don't know. I'm still very new to the eGPU project like you, but I happen to know the thing about what I said on the last post.

Yeah, it does not run hybrid graphics but switchable graphics instead.

In the old switchable graphics implementation both the iGP and dGP can talk directly to the monitor, flashes flicks of black screens as the graphics switches, unlike in Optimus/Enduro where the dGP has to talk to the iGP so that it'll pass the signals to the display.

Looking at your system, is it a pre-optimus implementation model? I'm not sure if GMA 4500 had Optimus. I had a Penryn Low Voltage (P Series, not L series) some years back and it only had switchable graphics.

mSATA slot has SATA pins 23,25,31,33 rather than pci-e pins as is required for eGPU use. Your only choice then to connect an eGPU is via the wifi slot which is definitely pci-e.

The BPlus PM3N has markings to show where to cut to make it a half-sized card to fit your half-sized wifi slot. If require concurrent wifi along with the eGPU then consider a USB dongle OR you might get lucky and have USB pins (36,38) connected to the mSATA slot, without any bios whitelisting, so could use an internal US$6 USB mPCIe wifi card.

If the wifi slot has USB pins connected AND it's not whitelisted then consider using the PE4H/PE4L's USB port to host your external wifi when internal wifi slot is being used for eGPU purposes.

A DV4-3xxx DIY eGPU implementation would be most welcome. I believe HP sold quite a few of those units. Still recommend a NVidia solution over AMD for better performance on a x1 link and superior driver features, including the NVidia Optimus.
