Hey guys, Thanks for all the help getting my egpu going with the new laptop. I also solved the buzzing sound when connecting to the receiver, it was a grounding issue from cheapo surge protector my computer was attached to. I have my vostro 3560 attached to a very well overclocking MSI GTX 680 lightning @ 1398/6600mem cooled by an H100 cooler via ziptie mod. I'm in process of running the benchmarks at my 24/7 speeds. Might crank the voltage up later for some suicide runs since the lightning can be cranked without hardware mods. Pictured below is the enclosure, large, but I don't really need it to be mobile besides the occasional friend gathering. This is a desktop replacement setup for me, since I literally sold off my desktop when discovering the egpu. 3DMark 11: Overall P8801 Graphics: 9554 Vantage: Overall P26760 Graphics 30176 Heaven 3.0: 100.5 avg fps, 2531 score 3Dmark 06 (crappy): Overall: 21557 [ATTACH=CONFIG]6268[/ATTACH][ATTACH=CONFIG]6269[/ATTACH] Nando4 edit>>

Thanks Nando, I did find that thread last night and even contacted tondy and he was very helpful. However, for some reason I can't get a 32bit/A pci compaction to work on my computer without giving some kind of "can't find c drive location" or something like that when trying to chainload into windows. However I have found a work around to get optimus working. I have to boot into windows with dgpu disabled and egpu plugged in. I will initially get a very buggy, jumpy windows, but if I hibernate then resume I"m completely fine after that and still have optimus enabled. So for now, I'm happy. I would of liked a solution as easy as my e6520, but for now I"ll take what I can get.

Hey guys, I've just upgraded my laptop to an i7 3612qm dell vostro with a 7670m dgpu. I've had my egpu working well with my e6520, but cannot get it working with this new laptop. I am using the same ssd, so the egpu setup 1.x partition was still there. I reran the devcon file updater, but still get a problem with the "ichip" being wrong when I load the egpu setup. This means the iport settings are not available in the egpu setup 1.x, and that I can't disable the dgpu. It says you can edit the intel.txt file to get the ichip working, but when I go in there there are no DIDs for series 7 chipsets, and if there were I really wouldn't know how to edit it to make the ichip work. The nvidia 680 is recognized, and shows no errors in device manager, but cannot be used. I have uninstalled the catalyst drivers for the 7670m, and installed nvidia drivers for the 680. The 680 shows up in device manager, but nvidia control panel gives error about no nvidia gpus attached. Also, after uninstalling the catalyst drivers, the intel 4000hd shows an error (either 43 or 57). I also can't just install intel video graphics as it says something about not meeting minimum requirements. Please help. Update: found the patch for series 7 cpus, this allowed me to disable dgpu. however, after finally getting the intel hd 4000 driver installed the screen becomes erratic once windows loads. If I do not disable dgpu it will boot into windows fine, show intel hd 4000 driver (and standard vga for dpu). I can then hotplug egpu and get it to work correctly, alothough optimus cannot be enabled this way. Any thoughts on why disabling dgpu (no compaction/anything else) with setup 1.x causes screen to go crazy once booted into windows, and what can be done to help?

Hey guys I have a few unresolved questions. I'm still having a static/crackling sound when using my HDMI ports (either from onboard or egpu) to pipe sound to my receiver, this crackling also results in a huge drop in performance. This doesn't happen when not connected to the egpu. I have a dell e6520 i5/8Gb, and use an express card connection. HDMI is the best way for me to get high quality sound digital sound to my receiver, so I would like to get this working. The problem gets worse the higher the load on the computer. My second question kind of builds on the first. I'm looking to upgrade to an i7 quad core laptop, either another e6520/6420, or an HP 8560/8460P. However, the HP doesn't have onboard HDMI so I will def. need my HDMI working through the GPU. I have also heard this can reduce the processing power of an egpu since some of the bandwidth is used for sound, anyone know how drastic this is? The large performance loss from the crackling seems too drastic to just be pci bandwidth sound allocation problems. Also, anyone have experience with a 8560p for egpu purposes, any hiccups in installation? Also, with the 8460P, it says "No switchable graphics", does this mean optimus drivers can't be used if I were to get a laptop with an ATI dgpu? Also, last question, my current e6520 doesn't come with the nvidia 4200m like the new one I"m looking at getting does. Does the e6520 having the 4200m somehow disable my ability to use optimus?

I am having a problem with trying to get sound out to my receiver while hooked up to the egpu. I have disabled sound processing from the video card, to decrease pcie lane traffic, and have the receiver connected to my laptop's native HDMI port. I get sound, but there is gargling and static audible at low sound levels (as if the sound floor has rose considerably). Additionally, while playing games I have noticed VERY large performance drops with the receiver connected compared to unplugged. Anybody have any thoughts? I have a Dell E6520, and hot-plug once windows boots. I did not use the setup 1.x thing yet, or do any kind of compaction. Would these help?

Hey guys, I have a quick question for those knowledgeable on pcie scaling. I'm currently planning on running an OCed gtx 670 or 680 with my epu setup. I have the equipment for a 1.2opt connection. I've seen that I can get about 70% desktop framerates with these cards. Now, how do you think scaling will be with a card like the gtx 690 IF it could work (heard impossible), or the new Titan coming out soon (performs similar to 690 but single core), would the ~2x pcie 2.0 bottleneck limit the card to less than ~60-70% performance?

Thanks, I just received my egpu stuff last night and found the same thing. So no harm in always hot-plugging/ejecting?

Yeah Rhakis crossing even stutters with my desktop's sli OCed 670s, thx for fps cap tip, and thanks for input! I see you have an e6520 as well, any problems with this particular model with expresscard hookup?

I would like the honest opinion of some of the egpu owners out there with a 1.2opt setup and a gtx 670/680. Can you get smooth framerates at "mostly high" settings, 1080p 60hz, on current games? I'm looking to possibly replace my desktop, at least until 2014 when I can evaluate the thunderbolt market and decide if I want to go back to desktops. I specifically play Diablo 3, Borderlands 2, and Starcraft 2. While I know I cannot get the performance of a desktop, is the ~70% desktop framerates pretty uniform throughout current games with an egpu?

I'm sorry if I missed this somewhere in the main egpu thread, but how much of an %fps advantage does the current thunderbolt solution have over a 1.2opt connection for dx10 and dx11 games? Using say, the OPs gtx 670? I don't want to hijack a thread, but very curious about this as I'm currently putting together an egpu setup.
