This is something that's been bugging me for quite a while. Laptop only (no monitor hooked up via VGA): all well and fine Laptop OFF: Plug in VGA cable Speakers slightly pop and make a "sssssshhhhhhhhhhhhhhh" noise - never ends. Stops when laptop is powered on. Laptop ON: Plug in VGA cable All is well Turn off laptop "sssssshhhhhhhhh" noise starts. It never stops. It's not particularly loud, I can only hear it when everything else is off. --- I have no idea if it is my monitor, cable, or something else. It's an older monitor, that get's an image burned in in about 30min - it is rather dated. IIRC it happens on my other display as well. The one I hookup to at work I cannot tell if there is an issue due to the ambient volume. Regardless, something doesn't seem right. Any ideas? Thanks.

I wouldn't mind trying this. Although, do I need to run Setup 1.x for PCI compaction or a DSDT override? Seeing I have to use both to get it to work in Win7/8.1 would be hard in a Live USB operation. Leaning that I probably won't need to do so. I can try Live USB tonight to see if it works with a single card (R9 280X). Which Ubuntu distro would you recommend I try? Going with 13.10 for now. -- Just waiting till I get home, got drivers installed.

Ah true. I looked around to see the SATA speed for the Y510P, I only came across this: Re: Lenovo IdeaPad Y510p HDD Question. - Lenovo Community @emregezgin, could you run CrystalDiskInfo to see the SATA speed of the drive currently in your system? Look at the Transfer Mode section.

I looked around, sorry to hear about PayPal and Iran. I thought you might be able to send money out with PayPal, but you can't even do that >_> No free version for the software. @Tech Inferno Fan - ping!

I can already sense you itching to modify the card -- If it does work on EM series stuffs, I would like to see you test in Khenglish. I know you'd certainly push the card to it's limits to test it out.

Hopefully the price won't rise because of this. Would be nice to keep this full unit in the sub-200$ range.

You don't need BIOS modifications for any eGPU setup that I know of. For most eGPU applications you will need Setup 1.x It can be very zippy as shown in the two videos I made at the end of that thread. One of the better eGPU systems is a HP 2570P. Very solid IVB system. I personally would like to get one if I ever get the chance to offload my current system. See here for cable length: http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-38.html#post67617 naturbo2000 uses a 200cm cable. No change in bandwidth (actually 1MB/s higher) than my 60cm cable. So cable length doesn't matter. The performance on external is much, much better, so if you can run an external that would be much better. (I said 'much' a lot in that sentence..)

Ah, for Win8.1 you will need Setup 1.x for compaction and for loading the DSDT table. The DSDT table allocates memory blocks for devices on the system. AMD cards need a 256MB contiguous block allocated to operate. Only a few laptops will actually read the eGPU and allocate enough space (aka it's rare). You might just be fine with Setup 1.x only however. See my guide post in my signature if you want some more info on eGPU setup. Also see two videos I have made for working within Setup 1.x: http://forum.techinferno.com/diy-e-gpu-projects/2123-diy-egpu-setup-1-x.html#post78919 --- You don't need a PayPal account to send money to someone, you can use a credit card without setting up an account. https://www.paypal.com/us/webapps/mpp/send-money-online Hopefully that link works properly. You would type in your email in the appropriate place, Tech Inferno [email protected] in 'their email' and then 25$USD for the amount.

Windows 7 or Windows 8? Do you have Setup 1.x? Since it's a AMD card you might need to perform a DSDT override as well.

@kaladeth Nice to see such a nice improvement with a change in CPU. My i7-2620M is only a smidgen better than the i5-2520M you had. You are tempting me to upgrade to one of the nicer i7 CPUs lol. I see you have 3 displays. Have you done testing with 3 hooked up vs 1 hooked up? I noticed a pretty solid performance difference with a change in the number of displays active: http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-43.html#post74494 (1 to 6 displays in that test)

Personally I have a normal 2.5" SSD inside (Intel 520 Series 60GB - shoulda got the 120GB), and a 1TB drive in my multibay. Sadly I do not have a mSATA slot or I would have a mSATA SSD in there as well for random programs / games. I like only keeping certain things on my OS drive. I'd still keep my OS drive as a 2.5" SSD due to size / speed. Unless I had a computer with a M.2 slot wired PCIe, those things are absurdly fast (due to PCIe communication over the much slower SATA connection). So: 2.5" SSD + data drive in multibay. SATA speed might vary in the multibay. But don't be overly concerned about it. Pic of CrystalDiskInfo (kinda big):

What did you do to mount the PSU and GPU? I see the little slot cut for the GPU IO shield, but that's about it. For mine (dunno if you've seen it), I used steel pipe hangar and a custom IO shield with a little screw mount hole. Album: eGPU setup - Imgur

I acquired a Dell PowerEdge 6850 and a PowerVault 220S from my boss (so swell)! Since I don't have a desktop I figured... "how hard could it be" to make this server into a desktop! Answer: it's really heavy --- I mean difficult Specs: PowerEdge 6850: Four Xeon 7140M = Hyperthreaded Dual-Core 3.4 GHz 16x 4GB DDR2 @ 200 MHz = 64GB total 5x 450GB 15k RPM SCSI = 1.63 TiB total (Tebibyte/formatted) pair of 110V -> 220V 1500W transformers PowerVault 220S: 14x 73GB 15k RPM SCSI Notes about each PowerEdge 6850: came with Windows Server 2008 R2 | ugly for desktop OS | only supported 32GB RAM not terribly loud | with my audio setup it would drown it out | sits opposite side of desk so noise is tolerable Runs off of 220V | thus the 110V -> 220V step-up transformers HEAVY | I'm not going to your LAN party, sorry bub PowerVault 220S: SCSI connection | older SCSI hardware doesn't work with Windows Server 2012 R2 | so is sitting off to side unused WHY IS THIS SO LOUD I CAN'T HEAR WHAT I'M THINKING WHY DO THE FANS NOT SLOW DOWN For today's times, this is a bit excessive for the 1TB of storage it gives. I'll stick to external HDDs heavy | not as bad as the 6850, but still a chore to lug around -------------------------------------------------- Step 1 (OS): So I started by changing the OS. Pretty straightforward... not really. Since I want it to be a desktop and not a server, I initially tried Windows 8.1 (I like Win8.1). Turns out Win8.1 doesn't support more than 2 physical CPUs, which in this case isn't nice. I attempted to force more than 2 physical CPUs to no avail. You can see my efforts here: http://forum.techinferno.com/microsoft-windows/5607-windows-8-1-physical-processor-limit.html Since I'm a student, I was able to join the Microsoft Dreamspark and get Windows Server 2012 R2 Datacenter. Very nice! I then followed the information provided here to make WinSrv behave more like it's desktop OS counterpart: http://www.win2012workstation.com/ This got me a bulk of the way there.... or so I hoped. Pics: -------------------------------------------------- Step 2 (GPU): Here I was hoping I could just plug in a GPU and get it working after a driver install... heh. that was a funny joke... I cut away the backside of the PCIe 8x slot (wired 8x) to make it an edgeless connector. This was successful. But: Server PCI widths are not the same, double wide cards don't fit Server motherboard doesn't put out adequate power, assuming 25W instead of the normal 75W Reflectional thought: May have been a PRSNT1# and PRSNT2# issue which I discovered about later instead of the above Soooo, I bought a powered 8x to 16x extender cable. I knew coming into this I'd have an external PSU (ePSU). I soldered on a GND to the cable (only had +12V since it assumed there would just be one PSU and the ground going through the mobo and whatnot). And plugged this all together..... nothing. Got some reference material here: [Guide] Homebrew powered risers. So then I started looking around for why. I found this: https://bitcointalk.org/index.php?topic=36061.msg757661#msg757661 (With all the BTC and LTC mining, lots of info on risers) This turned out to be the ticket! I bridged A1 to B48 and BOOM, card turned on. Big thanks to @chmod1337 for his help with this section. I was doing this testing with an old 8800GTS (this is important for later). I finalized the extender by soldering the bridge nice and neat then.... (next step) Pics: -------------------------------------------------- Step 3 (case / making it look remotely decent): This will be just a series of pictures mainly. I used the same case as I did with my eGPU. Actually, nothing changed but the interface cable and a new hole cut. Quite nice. Images: -------------------------------------------------- Step 4 (Nvidia woes): 8800GTs worked great! It's actually what I'm using while I type this post up. GTX 660 Ti: Works during POST and other pre-boot environment areas, also in DOS Blackscreen and makes the system beep when it loads any thing else (and just before entering BIOS setup and DOS) Doesn't work for anything else @svl7 helped me with some info (paraphrase): nvidia loads a leagacy vBIOS for pre-boot environment and such, thus it worked here. But loads a different vBIOS for OS and such. This might be were the issue arises. (svl7, feel free to edit this to make it more accurate) I plan to get my hands on a friend's AMD card (R9 280X). If that works to getting me to the OS then: I jump around in an overly excited manner. Look in wallet and find nothing useful, and then proceed to halt jumping around in an overly excited manner. Realize this is a pure Nvidia problem and that their modern cards are far too finicky and can't use them for this Server GPU setup. Resulting in AMD being the choice for this Server GPU project. Newer servers may not have this issue. Thanks to @svl7 for help in this section! Quick Edit: The R9 280X works, albeit slowly. See the links at the bottom of post for results of that. Pics: -------------------------------------------------- Step 5 (testing): At the moment, I can't do anything too impressive. You can satisfy your appetite with this hopefully, more soon if I can get this working fully. NVIDIA GeForce 8800 GTS 320MB/640MB video card benchmark result - Intel® Xeon™ CPU 3.40GHz,Dell Computer Corporation 0RD318 Doesn't appear to use / doesn't actually use all CPUs: http://i.imgur.com/XxrZEB2.png -------------------------------------------------- Step 6 (endnotes): Carrying this up stairs wasn't fun. I'm not moving it more than dragging around a few feet. If this does end up working more than it does now, it'll be a glorious moment. Certainly look forward to it. I'll have more in this section later. --- R9 280X:: Link storage zone for writeup: http://i.imgur.com/KqH5rQU.png http://www.3dmark.com/3dm11/7807356 http://i.imgur.com/39D2ZH2.png

Alrighty I'll give it a whirl by prodding around with my multimeter and testing the grounds. I'll update this post with results. And I have another (actually finished this time) mod blog if this works --- All GND are connected to each other on the MOBO ONLY. The riser ground connections aren't connected at all Gonna have to fiddle around with that. --- NM, they are, I just had a bad connection prodding around. ---- GND doesn't matter.

So I ordered a powered extender 8x to 16x cable. This particular one assume that the same PSU would be connected to the extender and the mobo. However, in my case it will not be so. Picture from listing: So from this I can see that the +12V lines go to the 16x slot as intended with no feedback to the motherboard. Which of the GND wires should I hookup my ground from the PSU to? I was thinking of A4 or B4. Will be doing this without severing that line, with one of those inline crimp connectors. PCIe wiring diagram: semi-large image (don't want to resize as readibility issue) Or does it not really matter which ground I hook it up to? Thanks for the help. --- It appears for all intents and purposes, the ground you hookup to doesn't matter. I have also added a wire from the PRSNT1# to the 8x PRSNT2# to make sure both devices read that this is a 8x connection. Worked quite well.

Here ya go: Almost sleek narration to make it seem like I have some remote idea of what I'm talking about lol. --- As requested, showing minimal interaction and a fast bootup:

Hmm that's interesting. Hopefully you can figure out everything that is going on under the hood. I don't have any AMD GPUs with me to help you look around. Hopefully either Catalyst or some other utility can forcibly enable Crossfire (if blocked). Hopefully your 1x to 16x entender cable arrives next week!

Hookup an external display, disable internal (with the Windows screen layout settings). Run 3DMark09 and 3DMark11. That's usually a pretty good start to make sure things are working correctly.

The uninstall the GPU step was for systems with a dGPU. You don't have to do this step. While you can use the GPU on the internal display, you get lower performance. Recommend to use an external display. There is a significant performance gain.

Yeah since you have the i5 version you probably just have the HD 3000. (my friend has this version) Yeah it's just your settings in Setup 1.x now. If you can wait a couple hours I'll have a video of how you would go through Setup 1.x.

I'm not sure exactly what it says lol (never really paid attention), I know there are some blue lines of text rather than the 'no solution found' with red lines. I can take a video of how I setup Setup 1.x when I get home (few hours). Although you might figure it out by then.

Woot!! Since you don't have the dGPU version of the T901 it will be really easy. Just hookup the eGPU. In Setup 1.x: Set port to G2 Run the 36bit compaction in Setup 1.x (56GB or w/e it is) around your eGPU only, force nothing to 32bit Chainload. Install nvidia drivers Reboot Done

Here you go: https://dl.dropbox.com/u/19774443/ShareX/2014-01/sbdsdtoverride.7z Upon extraction you will see: SBdsdtoverride.aml and sbdsdtoverride.dsl I compiled the .dsl to the .aml already so you can just jump straight to step 12: asl /loadtable SBdsdtoverride.aml Hope that works.

I hope you aren't touching anything up there. You need to leave all of that section alone. Go ahead and upload your .dsl before you break something lol.
