Hi, this thread will be my "Blog" of the experiences and troubles with my S430 and the eGPU Setup. I am currently collecting the pictures and make videos of how I build my case. Updates will come regularly. Update from 12.06.2013: Hey, I got my PE4L 2.1b mod to work. Sadly I rarely have issues with the connection. I think that a downgrade to Gen1 link speed could fix the issue. Bplus now has a cable for the PE4H 2.4 that will allow me to run Gen2 and lucky as I am I was able to get my hands on a Cheap PE4H 2.4 from ebay. I also purchased the new cable from BPlus already. The plans about my case have also changed, I wanted to make a metal one and already had the plans layed out. But with the announcemend of payable Thunderbolt adapters in (hopefully) early 2014 I decided to just make a "cheap" case for these 6 Months that I'll use it. When the cases that come with the Thunderbolt adapter do not fit my needs I'll use the materials and layouts I gathered/made to make a metal case for the Thunderbolt eGPU solution. I will also make some minor changes to the XBOX 360 PSU. So until my new hardware arrives in approx. two weeks there will be no updates. Sorry. Until then Lets start with my System specs: Lenovo S430 3364-57G Core I7 3520M 2 x 2,9Ghz HT 2x 4GB Hyundai DDR3 1600Mhz Plextor 128GB M5S Travelstar Z7K500 500GB Intel HD4000 Zotac GTX 560 Multiview Windows 7 64bit Professional eGPU Setup Specs: PE4L 2.1b with PM3N XBOX 360 Power Brick 203 Watt ( 12V @ 16,5A = 198W , 5Vsb @ 1A = 5W ) DELOCK HUB USB 2.0 4 Port ext.

Windows 7 DSDT Override: File: DSDT Override + S430.zip The file contains a guide in german aswell. Die Datei enthält auch eine Deutsche Anleitung. DSDT Override for Lenovo S430 (3364-57G) and other Notebooks ===================================================== There is a short guide for the S430 and a long one for other Notebooks. USE AT OWN RISK. NO WARRANTY! If you have a S430 (3364-57G) and Windows 7 installed: Step 1: Open CMD in Admin Mode. Windowskey -> type "cmd" -> right click on it -> start as admin. Step 2: Navigate to this directory. Step 3: Type "asl /loadtable DSDT-S430.aml" into the commandline. Step 4: Reboot. Check Device Manager -> view -> resource by connection. If you have a "Large Memory" entry now, you're done. ===================================================== ===================================================== If you have no Lenovo S430 you have to go the full way. Step 1: Open your Device Manager and click on view -> ressources by connection. Step 2: Search for the last "PCI bus" entry. It should have a lot of subentries, including "Motherboard resources". Step 3: Write down or memorise the last digits of the second value inside the brackets. e.g. Entry: [00000000BFA00000 - 00000000FEAFFFFF] PCI bus Value to memorise would be "FEAFFFFF". Step 4: Open CMD in Admin Mode. Windowskey -> type "cmd" -> right click on it -> start as admin. Step 5: Navigate to this directory. Step 6: Type "iasl -g" into the command line. You should have some new files in your directory now. One of them should end with ".dsl". Step 7: Open the .dsl file with the editor. Step 8: Press STRG + F and search for the memorised value. Step 10: You will see a bunch of "DWordMemory" Methods, go to the end of that list, put your cursor behind the last "TypeStatic)" ( yes after the bracket ) press Enter and now copy the following at the place: QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x0000000000000000, // Granularity 0x0000000C20000000, // Range Minimum, set it to 48.5GB 0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB 0x0000000000000000, // Translation Offset 0x00000001F0000000, // Length calculated by Range Max - Range Min. ,, , AddressRangeMemory, TypeStatic) It should look like this: Now indent if you like for better readability. ( Notice the Method you inserted is a 64bit QWordMemory not DWordMemory ) Step 11: Go to the top of the textfile, you should see two lines that start with "AHCI" delete both and save the file. Step 12: Switch to the command line again. Type "iasl <name of="" the="" file="" you="" got=""><dsl file="" name="">.dsl". Step 13: Check the output, if there are 0 Errors you are fine if not check some DSDT sites like: DIY eGPU experiences - Page 1003 tonymacx86 Don't forget to thank them for their efforts. Step 14: If you got 0 Errors you'll get a "DSDT.aml" file. Type "asl /loadtable DSDT.aml" into the command line. Step 15: Reboot. Check Device Manager -> view -> resource by connection. If you have a "Large Memory" entry now, you're done. Hardware & Case XBOX360 PowerBrick: Q: Won't 198W be too much for a Molex wire to handle? Aren't you afraid of cable fire? A: Yes you are right, 198Watt would be too much for a single Molex wire, but I have a GTX560 that just consumes 150Watt. Molex oficially handles up to 11A per lane, what would make 132W on the 12V lane. I know I am slightly above that and tested the wire heat while my GPU was on maximum Load during a 3DMark benchmark. it got warm, but far from Hot. I would guess that the single 12V cable had about 26°-30°C and I decided that this is okay for me. Edit: I tested the temperature with a device now, the cables surface got 24,3°C warm. So please keep 11A per lane in mind and be careful! Cable fire is very dangerous. Test thoroughly beforehand! Q: Why do 5Vsb and PSU Enable go into the red lane? A: When you plug in the XBOX PSU it will be on standby and only provide 5V on the 5Vsb lane ( Vsb = Volt Standby ), to wake the PSU up there must be a 1,5V to 5V current on the PSU Enable lane. Only then you'll have power on the 12V lane to power your GPU. Q: Why did you seperate the GND lanes? A: I noticed that the 3 lanes get a bit too thick for my shrinking hose, so I split it up. The thinner wires handle up to 8A per lane and my GPU needs 12,5A so I am safe with my GTX560 in this case. The male Molex connector is connected with the female one on the XBOX PSU. The female connectors are for the PCI-E power adapters and the female floppy for the PE4L. I just cut them off from an old ATX PSU. Discontinued attempts PE4L Socket and Plug: I tried to connect the PE4L via a HDMI cable to get more mobility. Sadly it didn't work. I soldered everything right, but it seems that the impedance of 4 soldered bridges and one HDMI connection is too much.
