  1. eGPU experiences [version 2.0]

    Nvidia control panel now detected eGPU with new ATX PSU but when he try to access 3D settings page, he got BSOD. Already tried removing the driver using DDU & reinstall the driver. Below you can find video capture showing when it BSOD. Simple File Sharing and Storage.

    Hi nando, The notebook in question doesn't have dGPU, only Intel GMA 4500M. We already tried 306.97 but still same issue. Also using DDU to uninstall drivers. intel Pentium T4400 (2.2GHz, 800MHz FSB) Chipset ICH9M Bios is InsydeH20 Rev 3.5 V2.06 Intel GMA 4500M only 8GB DDR3 (4GB x 2pcs) Windows 7 ultimate 64bit eGPU used: PE4L v2.1b with PM3N mPCIe Asus GT640 DDR5 1GB (choose this coz low power draw only 70+w) Power Supply is 12V 7A 84W DC connector with D.i.Y step down module to let it draw the 5v to 3.3v and connect with floopy molex Also Tested with ATX power supply Both Nvidia control panel & ASUS GPU Tweak unable to detect the device even though both Device Manager & GPU-Z detected eGPU. One more symptom, when trying to connect external monitor to eGPU, system black screen/crashed/BSOD.

This issue can be fixed with x2 link. Fortunately, Dell Studio 1557, just like Studio 1555 & 1558, can support x2 link configuration (PCIe port 1 & 2). Also it seems, there are enough PCI bus space to support SLI/CFX configuration. So, my next plan are:- To get two PM3N (mini-PCIe) card to drive HD5870 on x2 link. [[Update 24 August 2011: Ordered 2xPM3N mini-PCIe cards]] (Optional) Get a PM3N card & Nvidia GTX460/470 card for x1.Opt link configuration on Asus K42JV notebook. (Wish) Get a PE4H-PM3N package & another HD5870 to setup CFX configuration on Dell Studio 1557.
  6. eGPU experiences [version 2.0]

    Your eGPU is running at PCIe rev 1.0 speed. This is why you are experiencing stuttering when playing games. Your laptop only support PCIe rev 1.0. Only Sandy Bridge laptop & above support PCIe rev 2.0 speed. Stuttering should be less with PCIe rev 2.0.
  7. eGPU experiences [version 2.0]

    That kinda disappointing. When you set to dynamic, did you try cold boot with eGPU connected? If yes & still got code 12, then the setting really doesn't do anything. Is this modded BIOS? If yes, then I can understand why it doesn't work.

  10. eGPU experiences [version 2.0]

    Sorry for replying late. I'm quite busy when you PM me (in the other forum). I see you already moved on & using Nvidia now. Anyway, I'll show how to mod AMD drivers to accept both integrated/mobility & desktop AMD GPUs. Download official drivers for integrated/mobility GPU from AMD/ATI website. Go to Packages\Drivers\Display\W76A_INF, open the C7xxxxxx.INF file & look for your device, for example:- Copy both lines & paste them in desktop drivers (C7xxxxxx.INF) in Packages\Drivers\Display\W76A_INF directory:- Note: If AMDxxxx.X is already exist, increment it. E.g. AMD9553.1 already exist, change the new entry to AMD9553.2, if AMD9553.2 already exist, change the new entry to AMD9553.3, and so on. Install the desktop driver. For successful installation, you'll need to disable driver signature (F8 -> Disable Driver Signature Enforcement). There is another trick to install both mobility & desktop drivers. What I did is install driver for integrated/mobility in Device Manager & for desktop driver, use the installer.
  11. Asus A42JV (K42JV) ON OFF Loop

    I tried one memory module at a time & tested on each slot. I also tested both modules on my other notebook & confirmed they're ok. Also, I did tested with another set of RAMs. Unfortunately, none of this change anything. I'm able to triggered BIOS recovery mode (it reads optical disc that contain BIOS UEFI file when booting with CTRL + HOME keys). This show motherboard not fully dead, right? Maybe failed when P.O.S.T.-ing? But I don't know what failed. The ON OFF loop must be means something. I wish someone know. I forgot to mention one thing; before this problem happen, last thing I did is exiting BIOS UEFI by pressing F10 (save & exit). Prior that, I didn't change anything in BIOS UEFI.
  12. Asus A42JV (K42JV) ON OFF Loop

    Hi all! My notebook somehow died a couple of weeks ago. It's not totally dead but now it ON-OFF loop when I turn on the computer. It's like this:- Turn ON >> boot up but with blank screen (no backlight either & go on like a minute) >> (auto) turn OFF >> (auto) turn ON for only one second >> (auto) turn OFF >> boot up but with blank screen (no backlight either & go on like a minute) and it repeats indefinitely until I turn it OFF by pressing the power button. Anyone know what this means? My best guest the CPU kaput; it tries to initialized CPU but failed. I troubleshoot it by putting a quad-core (i7-720QM) processor which I know this notebook doesn't support because this notebook is Nvidia Optimus powered notebook (it use Intel HD Graphics as primary adapter). With quad-core processor, it doesn't do ON-OFF loop but it stays ON indefinitely (with blank screen) until I turn it OFF. Specification:- Asus A42JV notebook (at some part of the world it's called K42JV) Intel i5-450M 4GB DDR3-1066 Intel HM55 Please let me know if you need more information. Thank you.

PCIe power connector Make sure you plugged all PCIe power connector on the GPU with 6/8-pin PCIe power connector(s) from PSU. If GPU have two PCIe power connectors & you think connected only one 6/8-pin PCIe power connector is enough, you're totally wrong. Floppy power connector (PE4L/PE4H) Connect floppy power connector from PSU to floppy power header on PE4L/PE4H Jumper (PE4L) Check out jumper settings in the manual which available from here:- PE4L v1.5: [url=http://www.hwtools.net/Adapter/PE4L.html]PE4L ( PCIe passive adapter ver1.5 )[/url] PE4L v2.1: [url=http://www.hwtools.net/Adapter/PE4L%20V2.1.html]PE4L V2.1 ( PCIe Adapter )[/url] ^top Common >>> I have problems when running eGPU Setup 1.30.

Boot Win7. Standby (not hibernate) your system, poweron your eGPU, resume your system. ^top My eGPU worked, then stopped working all of a sudden First thing is check your mini HDMI cable. 2 users requiring a replacement US$6-shipped cable to restore functionality. NOTE: This solution only for PE4L v1.5 & PE4H v2.4. ^top My eGPU hangs, particularly when doing a lot of graphics processing If you are running a Gen2-capable system (2nd gen i-core or newer) but not using a Gen2 capable eGPU adapter (PE4L 2.1b or PE4C 3.0), then you'll need to downgrade your link to Gen1 to gain reliable operation using Setup 1.30 Check your PSU is delivering the required power OR swap with another more powerful PSU and test again. We've found cheap double-rail PSUs might not deliver enough power. Eg: a Shaw 680W PSU has a 12V/16A and 12V/15A rail. The latter rail was insufficient to power a GTX470 requiring 225W of power. Also refer to Panzer's fuse bypass on PE4H ^top I can't play any game or run any benchmark for more than a minute or two before a complete system lock up - "black screen" of death. Pretty much the same issue as for Q4. Likely the PE4H's fuse is kicking in upon detecting a very high load and shuts down the power to your eGPU. This will occur with any of the heavy duty gpus like a GTX465+ or GTX560+. The solution is to set the PE4H 2.4 fuse bypass jumper (near the floppy molex connector). Older PE4H can do Panzer's fuse bypass to accomplish the same thing. ^top [ATI] Device Manager lists my eGPU without any errors but has have no resources against it nor is any external LCD detected This is a problem seen with onboard HD3450+HD6850 setups. The solution being a unified driver for both cards as provided by the DNA modded ATI drivers. ^top I have a PE4L + DC adapter. The eGPU isn't detected/fan spins up fast. Set JP4 on the PE4L as described so it draws 3.3V from the expresscard or mPCIe slot. Can connect a USB cable b/w your notebook and the PE4L to provide additional 5V->3.3V (regulated) if you find it's still flakey. ^top My eGPU recognises the external monitor but when I make it the primary it doesn't "turn on" and I'm simply reverted back to my internal LCD If you see a brief flash on the external LCD then it could either be a faulty HDMI cable connected to the LCD or the PSU is insufficient to drive the eGPU to actually display something. I did encounter a intermittently faulty HDMI cause this problem. Also, Optimus drivers newer than 258.96 will cause this if using a DVI-to-VGA adapter. ^top Upon powering my eGPU, the fan on the eGPU just spins faster and the card isn't detected. This indicates the eGPU is either not on the PCI bus or isn't getting 3.3V. Try unplugging, replugging the mini HDMI cable (expresscard solution) or hotplugging the PM3N (mPCIe solution). If the card is still not detected then connect the setup to another system's expresscard slot. It may be either a faulty expresscard slot or mini HDMI cable. Worth testing the eGPU in a desktop system as well. ^top I have problems running an Nvidia eGPU with an internal NVidia dGPU (supplied by nlooije/Khenglish) The trick is to get both an NVIDIA dGPU and eGPU working work under the same driver. This method assumes that the eGPU is detected in the device manager. If any errors such as code 12 or 43 are present check the corresponding items in the Troubleshooting section. If using the PM3N and it is not detected then maybe the mPCIe port is whitelisted, use the Setup 1.30 to unwhitelist. Download the latest drivers from the NVidia website or from this post by Tech Inferno Fan. Once the eGPU is detected, windows will automatically search for drivers through windows update. Cancel the search, and let windows install the standard vga drivers. In the device manager, right-click uninstall the dGPU and eGPU NVidia drivers. Use CCleaner to search for any residual Nvidia driversoftware and delete further. Install the latest Nvidia drivers. If everything went correctly then the installation software should ask permission to install the drivers twice, once for every card. Reboot and cross fingers. ^top My mHDMI cable does not fit in my half-height PM3N mPCIe socket Newer systems have been reported to have half-height mPCIe socket which may be limited in space for inserting a mHDMI cable due to the rigid connector. DIY solution: It is possible to strip the rigid connector to give the cable more flexibility and make more efficient use of the space. Use a sharp knife to cut along the ridge of the connector; be careful near the cable itself as the wires there are not protected. Inside the connector the wires are protected by a thick layer of solid glue. non-DIY solution: no commercial products have been found to solve this problem. (supplied by beatTheRestrictions) ^top Why does my USB/network/sound not working when enable my eGPU in Win7? Likely a PCI contention issue. Recommend setting up Setup 1.30, configured with a pci.bat (resulting from PCI compaction on your primary GPU + eGPU) prior to chainloading Win7. ^top Error 12 >>> My eGPU is detected and drivers loaded but has an error 12: cannot allocate resources against it in Device Manager Please check TOLUD on your notebook. For a reference on how to do this, please go to Pre-Purchase FAQ #2 (>> 2. How can I check if my notebook is compatible with an eGPU?). Many notebook vendors' bios were never designed to accomodate a desktop eGPU so do not setup PCI configuration space correctly to accomodate it resulting in the symptoms below. This will affect the DIY, Villagetronic ViDock and MSI Graphics Upgrade Solution (GUS) external graphics solutions. Symptom RequirementSIZE> Details with solution1SIZE> Device Manager error 12: cannot allocate resources Fix error Problem explanation: Windows XP/Server 2003 do not reconfigure the bridge windows based on the requirements of a device behind the bridge. This leads to a classic problem where a PCI device cannot be started due to lack of resources on the bridge, even though enough device resources are available to the system. For reasons such as this, a platform configuration that configures PCI devices at boot time works best. Some systems with more than 2.5GB RAM have no bios allocated free 256MB PCI window to host the desktop eGPU. Need to configure this correctly using one of the methods below: Solution#1 : (Update 3-14-2012) A DSDT override extending the root bridge into 36-bit can allow ALL systems with a 64-bit CPU and chipset (anything after 2007) to be eGPU compatible when used with Windows 7 and the latest iGPU/dGPU/eGPU drivers with up to 48GB of RAM installed. Solution#2 : Use Win8.x (WDM 1.2) that allows the primary video device to be disabled, freeing up resources for the eGPU to use. Solution#3 : Use Win7 to do a PCI relocation as described. Solution#4 : Use eGPU Setup 1.30 PCI Compaction. Solution#5 : [XP or Win7_with_XP_drivers] - disable onboard graphics using eGPU Setup 1.30 Solution#6 : install only 2.5GB/3GB of RAM, freeing 256MB of PCI Resource space. Solution#7 : Use Magma ExpressBox Full Driver described here. Greater than 2.5/3GB RAM installed Examples Neither the DV2000 or the 2510P had an appropriate PCI bridge memory window defined by the bios. The DV2000 too didn't have a free 256MB window when equipped with 3GB of RAM, the 2510P didn't have it's bridge correctly configured. In both cases eGPU Setup 1.30 was used to configure the PCI space correctly. ^top Even after successful compaction I still get a error 12: cannot allocate resources in Device Manager (Source: Tech Inferno Fan) The first thing to try is 32bitA compaction and see if that resolves it. If not, then what has been discovered happening is the I/O port allocated by compact gets moved by Win7. The I/O port allocated is shown as the last two echo lines in pci.bat such as : @echo -s 2:0.0 BASE_ADDRESS_5=2001 >> setpci.arg @echo -s 0:1c.1 1c.b=20 1d.b=20 >> setpci.arg The 0:1c.1 refers to pci-e port2 and the 2:0.0 refers to the PCI ID my GTX460 has. The 20 and 2001 means assign the port and GTX460 to use I/O port 0x2000-20FF. On this particular system, Win7 moves the pci-e express port2's I/O space to 0xD000-DFFF port instead which is odd so the GTX460 flags an error 12 since it can't get 0x2000-20ff. So the workaround is to change the 20 to be D0 and let Win7 have it's way. This can be done by adding two additional lines between "call pci" and "call chainload" to override compact's allocation. This setting will override any further re-runs of compaction as well. It should look like this in STARTUP.BAT file:- call pci setpci -s 2:0.0 BASE_ADDRESS_5=d001 setpci -s 0:1c.1 1c.b=d0 1d.b=d0 call chainload mbr ^top Error 42 >>> I get an error 42: cannot start device in Win7 Standby (not hibernate) your system, poweroff your eGPU, poweron, resume your system. ^top Error 43 >>> I get an error 43 against my eGPU in Win7. UPDATE: Use NVidia Verde 270.61 driver as described. First thing to replace is the mini HDMI cable. Could also be a faulty eGPU. Or if using a NVidia eGPU try: Ensure your PE4L 1.5+ or PE4H 2.4+ has the PCI Reset Delay slider set to 0s rather than 7 or 15. If it's the latter then upon doing a resume-from-standby the card will be delayed leading to an 'unconfigured' state, hence the error 43. Use Setup 1.30 to load a PCI dump AND use the 258.96 Optimus drivers (becak) Downgrade to 258.96 Optimus drivers (apollo-fox) (Update 26 July 2011) There is the Video cards->Initialize and Video cards->Save/Load dump features to eradicate error43. Ensure you are running the latest 275.33 Verde drivers + modded nvam.inf and the PCI reset delay slider on the PE4L 1.5/PE4H 2.4 is set to the 0 seconds position (not 7 or 15 seconds). Then proceed as follows: Boot eGPU Setup 1.30 with 2GB installed, run Setup 1.30, select to Video Cards->Save. If you are hotplugging after bios boot then need to select Video Cards->Save(Win) and follow instructions generated from within Windows. Install 4GB of RAM. Boot Windows. Create a devcon with 4GB of system RAM installed: eGPUeGPU-setup-mount v:devconmkdevcon Boot eGPU Setup 1.30, - select Video cards->Load to load the PCI space dump created when it was working with no error 43. - perform 32-bit PCI compaction on the iGPU+eGPU. - select startup.bat->edit, remove the 'call vidinit' since it might interfere with your load dump. - select Apply config.Run startup.bat - select Chainload mbr If still get an error 43, then repeat steps in (3) above but use 32-bitA PCI compaction method instead. ^top Optimus Setup: x1.1Opt/x1.2Opt >>> Lenovo Thinkpad/Dell Latitude: I boot with the expresscard in my system. The internal LCD doesn't appear/work. Neither do I see x1.Opt performance (NVidia) These system's bios will use the eGPU as the primary video if it detects it on bios startup. That means the iGPU will be disengaged. Problem then is the internal LCD won't work and neither will x1.Opt since they are both reliant on a iGPU to be the primary video card. Solution is to boot past the bios with the eGPU switched off, then either: hotplug the EC2C by hitting F8 to stall the Windows boot proces power on eGPU, resume in Windows boot Setup 1.30 and hotplug if need PCI compaction ^top Installing Nvidia drivers with AMD/Intel switchable graphics gives an error (supplied by appolo-fox) Installing Nvidia drivers with AMD/Intel switchable graphics may give you an error asking you to install Intel drivers first. Solution is to uninstall the switchable driver from your manufacturer (Lenovo in this case); system should revert to pure Intel driver via WinUpdate (if not, you will need to reboot and disable AMD discrete GPU with Setup 1.30 and let WinUpdate install or download newest Intel driver from their website. The Nvidia installer should be content with the pure Intel driver and install correctly. After Nvidia installation, reinstall your switchable graphics driver. [URL=http://imageshack.us/photo/my-images/811/amdintel.jpg/] [/URL] -> Intel driver provided by ATI (AMD). Nvidia installer exits with error. ^top I can't get internal LCD mode to work. This appears to be the case if you attach your eGPU after Win7 boots. So either hotplug your eGPU at the Win7 bootloader menu (hit F8 to pause bootup). Another option is to install and configure Setup 1.30 to detect your eGPU and configure your PCI configuration space prior to chainloading to Win7. AppInit_DLLs needs to be set for internal LCD mode to work For games to launch on the internal LCD on systems with an intel iGPU, the AppInit_DLLs needs to route via a DLL. NVidia sets this to nvinit.dll. During my tinkerings I have seen this registry setting missing so internal LCD mode didn't work. [H] "AppInit_DLLs"="C:WindowsSysWOW64 vinit.dll" ^top Non-Optimus Setup: x2/x4 >>> Set x2 link but mPCIe Port2 or Port4 enabled after reboot? On x2 setup (mPCIe Port1&Port2 or Port3&Port4), mPCIe Port2/Port4 must be disabled. If they left enabled, it can cause eGPU instability (e.g. 3dMark06 crashed while running benchmark). There are two methods for dealing this issue. First Method: modded PM3N (Source: Tech Inferno Fan) Second Method: two-pass script in STARTUP.BAT (Source: Tech Inferno Fan) ^top
