I do get this error though:

@Khenglish @plutomaniac I use the unlocked v209 BIOS if that makes any difference?

@kenglish Hi buddy! Do you know any attempts of unlocking the ME for an ASUS G46VW? I could donate some $ for you if you'd like to help me! For me the reference clock is grayed out in all versions of XTU that works for win 8.1. Thanks buddy!

Yeah that would really be something =) Who knows, maybe they'll make a portable version of this box with a data cable, sonnet style? I hope you didn't take my criticism personal, in that case I must apologize to you! At least to me, when ever a built is large enough to be a PC on its own I really don't see any real benefits of it, except that it's a super fun project, which of course should be enough for motivation don't get me wrong! We can't deny that we are making performance sacrifices going the eGPU route and the very important benefit for me is portability. I love the thought that my setup can make it into a backpack when going home to parents for holidays or visiting a old friend for a weekend of intense gaming. I must say it has really enriched my life! For me this MSI project brings nothing new to the table and I assume it will cost piles of $$$$. With those money you could probably go crazy and buy a macbook pro with the most hardcore i7 quad version + 2x Akitio's for a 32Gbps SLI setup =)

It's a nice concept and all but when the "expansion box" is as large or larger than a desktop computer (no mobility) I don't really see the point, especially when you must dedicate your laptop on top of this box so you can't hide it easily. When looking at the laptop itself I'm extremely curious what they packed in there, did they manage to put a real i7 quad in there or the shitty "u-version" (excuse my language)? The eGPU port is also very very interesting! Maybe they got something that matches the TB2 in performance or better? My thoughts goes directly to DIY (assuming no u-cpu): Ditch the hideous box and make something portable out of it instead, love it!! Reading a bit more and see that you can't render the eGPU on internal screen killed it for me Repost of the review that @jcagara08 posted earlier: http://www.kitguru.net/components/graphic-cards/zardon/msi-gs30-shadow-and-gamingdock-preview/ Judging by the cooling assembly (dual heatpipes and blow outs) it could actually be cooling a 45W cpu, what do you think?

@ha1o2surfer Hi buddy! I must ask, how do you keep your CPU that cool, Would you like to describe what your process is for achieving this? Your CPU heatsink looks as tiny as this one too? (jesus!) I also use liquid metal between heatsink and CPU, my clockings are 3.9GHz (1-core), 3.8 GHz (3-cores) , 3.8GHz (2-cores), 3.7GHz (4-cores) . Any tips would make me glad. Thanks!

The only thing to do now is to test your GPU in another computer/adapter, maybe there is another eGPU forum member close to you? Sent from my iPhone

I don't use power to the riser for GTX 970, just Akitio PSU + PCIe 2x 6pin from ATX. Have you tested w/o power to the riser?

OK that's a bad sign. The fans should start spinning when: 1. the Akitio PSU is plugged in and SWEX is turned on 2. Thunderbolt cable is plugged in to the system = this is when the fans should spin up If thunderbolt cable isn't plugged in you wont get power to the PCI slot. I can't really think of any idea to check the GPU w/o another computer. Your riser, does it look intact? No loose pins or so? Please share a photo of your setup. PS. If you happen to have an older PCIe card or GPU, test that one to see if it seems to react.

The GPU fans are powered by the PCI slot, that's not an indication that the ATX is working. My rutine is the following: 1. Connect PCIe power from ATX + connect power from AKitio PSU 2. Power on the ATX via SWEX 3. Plug the thunderbolt cable to the system = fans spinning up and then settles a little 4. Safely remove hardware, ejecting eGPU from the list (if detected) 5. Unplug TB cable, wait 2 seconds 6. Re-plug TB cable = fans spinning up again and then settles 7. Check device manager for your eGPU under display adapters (right-click and scan for hardware changes) Any improvements? PS: I'd absolutely not have the PCB side of the GPU resting against metal, that's not good at all and will eventually cause damage to the GPU (shortage etc.). Use an old CD plastic case/cover or something non conducting to support the GPU.

Hi guys. I'm gonna put this question out here: Do anyone have the knowledge of modding the output voltage of an AC-adapter? I'm currently interested in the 19.5v 16.9A M18x XM3C3 PSU (this is not the DA-2) GOAL I want to modify the output voltage of this adapter from 19.5V to ~12.7V while maintaining the 330W max output. An interesting video touching the subject can be found at youtube here: If there is anyone having some ideas how or if this can be achieved, please let me know! I'm not interested in using any adapting/convering board, I want to modify the internal components. //Jacobsson EDIT: This seems very possible by resistor modding, one unit is coming my way! EDIT2: Read that this PSU can be pushed up to 440W!

Hi Arise. I'm still investigating how to control the fans, when running FC4 for instance I can see core temps of 96c, while fanspeed ~4100RPM (according to NBFC) :S I just now realized that you've uploaded your profile a long time ago and I totally missed it the first time =) Have you done any improvements to this profile since the upload or do you use this as your current? I'm going to test it when I get home tonight and see if it works for the G46VW as well. Thanks for the good work buddy! EDIT: Did a test and it worked, but it only pushed it to 4000RPM. Do you think it can be changed to achieve 6000RPM?

It works excellent for me!

@Kaas93 Thanks buddy, I think it looks great! A lot of room for a big card both in length and height.

@Kaas93 I love it! Could you provide more pictures of your setup? I'd like to see some pics inside the enclosure with gpu mounted.

This is awesome!! I'd love to see what that little beast brings to the table One thing you should be worried about is the height of the card though, that if you plan to have a closed implementation.

Some cards are fine with the 25W from AC-adapter to the slot, some cards require the full 75W (therefore a powered riser is needed).

I'm sorry buddy but the PE4L and EXP GDC both use 5GB/s so no difference there. What system are you using?

@jcagara08 Whaat? That's weird! So you didn't change the AC-cable, just went straight to the wall outlet?

@rossysaurus VOLTAGE RAMP UP I'm pretty sure know what the problem is now, not 'over current protection' but rather 'voltage ramp up time', this triggers the DA-2 to shut off. A theory is that this is implemented on purpose to prevent us for using the DA-2 as an ATX PSU (I don't know about that). I follow this thread for info: SPCR • View topic - Dell DA-2 Power Brick Help BAD MOLEX CONNECTORS There seem to be huge voltage drop off in the DA-2 cable and molex connectors as well, some users had success using screw type terminals in order to prevent these drops: "don't use a molex connector, splice+solder the wires directly, or install a screw type terminal. I am currently using the latter. Voltage at the brick is 12.4v, at the Pico it's 12.14. Before that it was dropping to 11.5v with a molex conenctor" REPRODUCABLE BLACKOUT SCENARIO The 'voltage ramp up time' theory seems to be be in line with my symptom benching the Sky Diver demo, the demo normally goes black for a 1/4 second and then full load the right after (like a cut scene), this triggers the DA-2 to black out. Sooo, a pico PSU in between seems to smooth things out for most people, the answer lies in there, but what?... caps? TESTINGS In order to rule a bad Molex connection of my last DA-2 setup I'll now do this: Working scenario as reference: Akitio PCB + x16 slot: Powered by Akitio PSU (just connecting it as usual) GPU: ATX 2 x 6-pin = No problem at all. Test of possibly bad Molex connection to the slot: Akitio PCB + x16 slot: Powered by Akitio PSU GPU: Powered by DA-2 (have to make a 2 x 6pin connector for it) If this works, then the problem lies in molex connector, but I highly doubt it. MAXWELL GPU & POWER SPIKES Here is a very interesting article about the power spikes in the Maxwell arhitecure: http://www.tomshardware.com/reviews/nvidia-geforce-gtx-980-970-maxwell,3941-11.html

@rossysaurus Very nice! My Zotac GTX970 seems to peak around 180W (using watt meter) so maybe that's too much for the DA-2. Weird enough I can reproduce the black out-problem by running Sky Diver demo in 3Dmark, it happens just after she has landed and just before entering the big cave opening. This rules out the temp issue since my DA-2 is not hot to the touch. I'm more into the voltage drop issue, I should try to measure the voltages during the test once and for all to see what's going on.

The price is not right I min opinion, it seems like they all cost ~$25. Making your own would probably take you down to ~$5 5.5/2.5mm Barrel PCIe 6-pin extender

The non-solder variant would be this instead:

Red wire must be center pin on plug (aka a center positive barrel)! EDIT: The barrel in the image is just an example, choose a barrel with thicker wires than this. See http://forum.techinferno.com/enclosures-adapters/10090-visual-guide-opening-akitio-thunder-2-pcie-box-powering-via-barrel-plug.html#post134535 for picture guide to do this. Don't want to solder? Use this screw terminal variant instead available by searching ebay for "5.5X2.5mm DC Power plug Terminals Connector Adapter Power -female" <A HREF="http://www.ebay.com/sch/i.html?_odkw=5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power&_from=R40|R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power+-female.TRS0&_nkw=5.5X2.5mm+DC+Power+plug+Terminals+Connector+Adapter+Power+-female&_sacat=0"></A>
