  1. eBay item ID 172611041079 in case you want a look.
  2. No worries mate. Are you UK based and have you bought your EXP GDC yet? I'm selling mine as have been bitten by the bug and now building a desktop, plus my wife wants the laptop back to normal! It's as new, with all cables and boxed and can do it for £35 delivered.
  3. Hmmm... It's hard to say really, yours was released around a year and a half after mine and Toshiba started whitelisting the mPCIe slots at some point. I don't think it's a show stopper as I obtained a modded BIOS from bios-mods.com after asking in the requests forum and I think these can remove that whitelisting if you specify that as a requirement. I think off the bat, I couldn't say yes or no since yours was manufactured later and features a completely different chipset and processor brand but that's not to say it won't work. I took a punt as there was no info on this site from anyone trying with my laptop and it paid off, but maybe I got lucky? Good luck with it though!
  4. Maybe, what is the date of manufacture, what is the chipset, motherboard and laptop specs? Similar to mine?
  5. System specs: Chipset: AMD Torpedo APU: AMD A8-3500M w/ Radeon HD 6620G graphics RAM: 8Gb dual channel Kingston HyperX DDR3 1600Mhz (limited to 1333Mhz by hardware) SSD: Drevo X1 Pro 128Gb SSD HDD (in optical bay): Seagate 750Gb 7200rpm OS: Windows 10 Pro Additional purchases for eGPU purposes: GPU: Sapphire Radeon HD 7950 Boost edition 3Gb DDR5 eGPU interface: EXP GDC Beast v8.4d PSU: ACE Artic Blue 750W PSU Display: 32" LG FHD TV w/ HDMI input (had spare) My steps: 1. Remove wifi card from mPCI-e slot on motherboard (behind central cover on underside of laptop) and wrap antenna ufl connectors in tape to prevent shorts. Place these out of the way. 2. Insert mPCI-e to HDMI cable into x1 slot (where you just removed wifi card from) on motherboard and secure with screw. 3. Remove case from EXP GDC Beast and switch power selections switch (the one closest to the edge) to ATX power. Reassemble EXP GDC Beast. 4. Connect HDMI end of cable from laptop to HDMI port on EXP GDC Beast. 5. Using supplied cable for EXP GDC Beast; connect the 20 pin and 4 pin to equivalent outputs on the PSU. Connect other end to the 8 pin input socket on the EXP GDC Beast. 6. Insert GPU into EXP GDC Beast and supply power from the PSU via 2x 6 pin connectors to the GPU. Connect GPU to display using regular HDMI cable. 7. Plug both laptop and PSU into mains electricity and power on the PSU - EXP GDC Beast should light up (green in my case) and GPU fans should start to idle. Also power on external display and ensure it is set to correct input. 8. Turn on laptop. Windows should boot normally. In my case Windows detected and downloaded drivers automatically for the HD7950, albeit not the most recent ones. 9. After a required restart the external display should now be working and Windows had automatically installed Radeon Settings for me. The internal display's resolution will now be all screwed up. 10. To prevent a black display on both internal and external with just mouse cursor - with eGPU powered off start laptop and in device manager navigate to 'Display adapters' and right click > uninstall on the Radeon HD 6620G (inbuilt graphics). 11. Prevent Windows from automatically downloading drivers for devices (Google the process) to prevent the uninstalled inbuilt graphics drivers from reinstalling. Shutdown. 12. With eGPU powered; turn on laptop and navigate to AMD's driver update site (internet will now have to be got to via ethernet port or using USB tethering on mobile phone). Do not download the 'Automatic Detect' tool. Use the manual search function and download the latest driver for your GPU and OS (~530Mb). 13. Attempt to run the .exe - it will extract all the required files to a directory, make a note of this location, and then it will attempt to install the drivers but will fail with 'Error 174: Unexpected configuration' or something along those lines. This is fine, cancel out of the installer. 14. Back in device manager; right click GPU under 'display adapters' and select 'update'. Opt to install manually and browse to the top level 'AMD' folder where everything extracted to before and let Windows search for the latest driver in there. This will update drivers to their latest version. 15. To use the latest version of Radeon Settings that came with the ~530Mb download; uninstall the old version in the usual Windows way and in Explorer, navigate to the AMD folder again and in the search box at the top right of the window type "cnext". Run cnext.exe (or cnext64.exe if appropriate) when the search has finished and this will be the version that starts with Windows from here on in. And that is it! Really simple, no setup1.x required, no extending 32 bit space, no chainloading GPU-z confirms that the mPCI-e interface is running @ x1 2.0 which is good news also. I have also purchased a x1 PCI-e 15cm extension which is basically a riser connected via a ribbon cable to a x1 PCI-e connector which I have ran through the chassis and secured the riser to the outer edge of the laptop where the optical drive used to be (since this has been replaced by a HDD caddy). Since I need the laptop to still remain portable this prevents me from having to have fragile cable hanging out the bottom of my laptop when I'm on the move. Additionally I have purchased a midi-ATX desktop tower to contain the EXP GDC Beast, GPU, PSU and cabling. Space was not a concern for me with this build, price was my main concern, and this case looks smart, has additional cooling and was cheap so suited my requirements. It also gives me a platform on which to build a desktop gaming rig down the line as and when I can afford to buy parts, at which point I will return my laptop to it's standard form. I have successfully played BF4 on ultra settings (but with textures set to lowest setting to help with bandwidth bottlenecking) @ 1080p for 3 hours straight with no issues. I have done similar with FarCry Primal but had to reduce resolution to 720p to get a solid 60fps. Seems bullet proof so far! If you have any questions or want me to run any tests or benchmarks then please let me know.
  6. Literally this was plug and play, or at least the way I did it, it was. Don't think I did anything special though. Will make a full write up in the implementation section soon since there was nothing for this model.
  7. Well more digging has revealed on the Banggood page for the EXP GDC Beast V8.x that Toshiba L700 series laptops have been compatible so that has left me with a somewhat more positive vibe about the whole deal now. With my new-found confidence I began searching for a budget PSU that wouldn't need any bodging and would comfortably accommodate the power requirements of the Beast and the HD7950 so dropped £30 (~$40) on an ACE Artic Blue 750W ATX PSU - by no means top end but with 2 6pin PCIe connectors rated at 12V 32A for the HD7950 and a 20+4pin rated the same for Beast, I'm happy that I shouldn't need to do any modifications and I'm much happier with a legit entry level PSU over a potentially dodgy 220W 'Dell'. I still have a concern over my choice of GPU card but time will tell if I've made a mistake or not. If it bombs then I can always sell it on and go with the crowd and get an NVidia GTXxxx. I really do hope though that what swings most people toward NVidia is that they want to make use of the ability to run the internal display - which I neither want to nor can do (not Sandybridge CPU)... Time will tell. Feel like I'm talking to myself poor me! Lol
  8. Like a clown, without doing any research (again!) I've gone and bought an Sapphire Radeon HD7950 - before reading on here that AMD cards can cause headaches and are generally offer less performance in an eGPU format. I thought the only difference between the brands was use of the internal display (which I wasn't bothered about) and when I saw that the AMD card offered more bandwidth than the similarly priced GTX 660Ti I pulled the trigger - thinking bandwidth problems were my enemy over mPCIe 1.1 x1. But I guess I have to make the most of what I got now so will have to see how it goes Also, can not find a single example of somebody using a Toshiba Satellite of any variant in the implementation guides or work in progress areas - so not holding my breath that this is going to be an ideal candidate for use with an eGPU. Boo.
  9. Hey hey! So this isn't my first post - already posted in the eGPU top level asking for help but didn't realise you had an intro thread too! Completely randomly got onto this forum after a slightly inebriated buying session the other night. Long story short I have a EXP GDC Beast on the way from Gearbest so I'll probably get that some time next year and a Radeon HD 7950 from a guy on eBay winging it's way as of tonight before I really got reading the forum and finding out that AMD cards offer less performance and are more unstable than their equivalent NVidia cards - so off to a good start then! All I need to do now is buy a power supply that won't supply the amps required and I'll have a complex looking paper weight! If you have any sympathy for this idiot then please check out my thread here: Thanks for introducing me to my next money pit! shudda bought a desktop
  10. I have not looked at the list of approved graphics cards for the EXP GDC, I was not even aware such a thing existed, I'll look into that when I finish work. Just to be clear though, will there be no conflict between using an all AMD laptop and an NVidia graphics card if I chose to use one of their products? I also did not realise that the EXP GDC could supply 220W through the PCIe lane, the description on the Gearbest site was pretty thin on specs. Also, will there be a limit on performance due to the CPU in my laptop meaning the best card I can afford may be pointless and a waste of money - is there a 'sweet spot' so to speak in striking a balance between what my laptop's hardware can make use of, the performance of the eGPU and price?
  11. Evening all, Completely new to the concept of using an eGPU with my laptop so really looking for some help and insight from the community. I got an ad suggestion a couple nights ago for an EXP GDC Beast from Gearbest and as I had greased my wallet hinges with a few drinks, a few clicks and it was purchased - without having done a shred of research! So now I'm in the position of being committed and having done some reading I've come up with more questions than I have answers. I should probably start by linking the eGPU dock since I've no idea what revision it is: http://www.gearbest.com/laptop-accessories/pp_229101.html - can anyone let me know what I have actually ordered??? Secondly I should detail my laptop: Toshiba Satellite L755D-12L (PSK32E-01M006EN). I have upgraded the CPU to an AMD A8-3500M (Llano) which brought with it the GPU AMD Radeon HD 6620G and I have installed 2x 4Gb Kingston HyperX DDR3-1600 RAM modules and also a 128Gb Drevo X1 Pro SSD and a Seagate 750Gb 7200rpm HDD in the ODD bay and it is now running Windows 10 x64 - everything else is standard as per online specs. I have dug down into the laptop using a variety of programs - CPUZ, HWInfo etc. and also identified that the one mPCI-e slot currently used for the WLAN card is v1.1 x1 - I understand that this might be relevant! So my questions for starters are; is this even possible with my laptop before I start to shell out for a graphics card and PSU? What kind of graphics card should I be looking for, NVidia, AMD, since my entire laptop is AMD based? What kind of external PSU should I purchase - can this be done with a good laptop PSU and the card be powered through the EXP GDC or do I need a traditional desktop PSU? Can I purchase a card for ~£70 ($85) that will give me a decent improvement over the current onboard graphics (which are pretty good for a 5 year old laptop!)? Are there any other questions I should be asking that I haven't already? Many, many thanks for your time!
