X230T: Final straw... HELP!

Hey all. I'm looking for someone who has actually had a Lenovo X230T work with a eGPU setup. Right now I'm trying to get a Nvidia GTS250 to work on my 16GB X230T with no luck, and want to make sure I can even get the thing to work in the first place before upgrading video cards. Here's what I've tried so far:
Update Bios to 1.11 Sep '12 Bios for TOLUD support
Disabled HD4000
Turn off computer
Plugged everything in (PE4L 2.1b-GTS250-SWEX-Expresscard) and powered Video card up (fast fan)
Turned on X230T (Fan Slows, BIOS resets then starts again into windows)
At this point the GTS250 is in Code 12, install Nvidia Drivers anyways (Nvidia System Check detects and installs drivers)
Asks me to restart, so I restart with eGPU still powered on
Restart as normal (no bios reset)
Still code 12 on start up, no external monitor output through GTS250, Nvida Control panel says no Nvida device attached and no GFX card/monitor is avialable in Screen
Resolution menu

My attempts to troubleshoot:
Remove 8GB stick (No joy)
Remove all 16GB and replace with original 4GB (No joy)
Change Expresscard speed from automatic to Generation 1 (no option for Generation 2 only automatic....no joy)
Change Jumper settings and Switch settings from 1-2 to 2-3 and I've tried each delay on each option (No joy)
Leave HD4000 enabled, start with eGPU on and attached, detach after bios, sleep computer from windows, reattach eGPU, resume and install NVIDIA drivers (No joy)

Other than performing a Setup 1.x or trying a newer Fermi Card.... I have no idea what could be the issue. I'd get a Fermi but want to make sure something isn't wrong with the X230T/my PE4L.

If anyone can offer some additional advice or get with me to determine the problem, that would be much appreciated.

Thanks,

Joe

 

You might have too much RAM installed. For some computers, you have to have less than 4gb of memory because you bios cannot allocate enough resources. If you want to experiment, try putting in a 4gb or less stick of ram and see if it works.

 

Thanks but I've tried it, really not sure what to do... My next step is going to be to try getting a Fermi/Kepler card and give it a shot. Perhaps mine is too old for my computer to figure out its resource allocation or w/e.
There's got to be someone with a X230T out there?

 

Oh wow, I really wasn't paying attention while I read that. It could just be that you need a 4xx, 5xx, or 6xx card. I know those work, but not entirely sure whether older NVidia cards work. And I heard somewhere that the fermi and newer cards manage resources but better.

 

Well I guess that's my next course of action... I'll expand upon this thread once that fails I'm sure
