DIY eGPU experiences

[Jack]

I think that sounds like the card stops sending a signal and stops functioning because it is overheated. I do not know why it would do this when others do not. Lets hope someone else replies to you now.

I know that this has probberly been asked before, but i just cant find the answer in over 300+ pages of this thread

but can the lenovo t410 nvs3100 512mb run the optimus tweak??


Edit:

As for the card overheating?, i had this problem(on a desktop) and it was not getting clean power form the PSU.
try a water cooling block XD!!
is the card itself getting hot or is it a bad connection that shows it's self when it heats up?

[Lord_Epithis]

Yeah its the card thats getting hot. I can't tell whats it max temp is or anything, nor can I tell that the power supply is bad.

It also feels like the fan is not speeding up to counter these tempetures as well.

this is to especially thank Nando4 and others behind this amazing thread...


I wish to share my experiences so far.. of my DIY-GPU rig....
i use octane render (Octane Render - The Interactive Physically Based Render Engine) an amazing 3d rendeing software, which is CUDA based, uses GPU for processing and does path-tracing renderings at speeds more than 10x as compared to CPU based renderers; on my Dell Precision M4500 (win 7, 64 bit, nvidia optimus, i5, Quadro FX 880m-1GB, 4 GB RAM)..
its been 2 weeks since i assembled my rig, and it works like a charm...

i have documented my experiences on this thread (you might need to create an account to view this.. )

cheers and thanks a ton!

Hey all

@ epthius - try sticking a big A** fan in front of the GPU and see if that helps, otherwise i think your card may be dodgy.

2 things:

1. i wonder if thunderbolt would work well for the external GPU??

Also I'm having problems now... basically every time i start up with the DIY Dock, everything works fine until approx 1 or 2 minutes then my external screens freeze then my whole computer freezes before going blue screen "nvlddmkm.sys" it says that that was the cause.

My system setup.
Lenovo t410 , 1x PCiE , Geforce 8800gt, two dell 19" monitors and using a 1.5ft Mini HDMI cable

Any help would be greatly appreciated..

Since I've moved now, and built up my DIY ViDock again, I can correct my RE5-benchmarks.

So, I've updated my post, and also included benchmarks showing the performance impact of the DualIDA tweak as well as a picture of my setup.

(Nando4, can you please update the performance table for my D830?)

Well, I don't have a big a** fan and I am out of desktop room. So now I learn that I am using a defunct card unlike everyone else? Well then, congradulations to me for wasting 200 bucks unless there is a solution

Hi Guys,

Since nobody seems able/willing/ Keen to help me how to make it working, I'm seeling my brand new ViDock 3.... it's on ebay..... just browse for it.

Hope someone is more lucky than me.

Regards,
D.
P.S. I'm sorry if i've posted my announcement here, but I've contributed as well with my experience (bad one obviously)

I am testing the trial version of Badaboom 2.0 before purchasing the full software. I was looking forward to using the built-in CUDA processing for transcoding videos to the Zune HD and BB Torch, but there doesn't seem to be much of a gain using the GTX 460 over CPU. Both transcode at about 60 fps on my system. Has anyone used Badaboom in the forum with better GPU benchmarks?

I'm just curious, have any of you tried Lucid Virtu? Does it work? It's desktop software that copies pci-ex videocard output to the IGP framebuffer. It basically does the exact same thing as what we're trying to do here (display on internal LCD), but it seems like it would involve less hacking?

it would be cool to have graphics power you could just plug into the laptop.
