DIY eGPU experiences

[Khenglish]

Lost my dmc4 crown, so I went and took the vantage one:

CPU and PCI-E are at 11% OC. Only overvolted the GPU just to break 11k.

Hey Khenglish, can you explain how you got the fan speed to be 100%, mine only goes up to 70% (Zotac GTX 460 Synergy 756MB).

Mine's a Gigabyte 1GB. Both nvidia system tools and msi afterburner can set to 100% for me. Honestly though, 100% is way too loud to have on outside a case for extended periods of time. I usually run 70%.

Alright, I finally installed Win7 to get past error 12. However, it's plagued with bugs. Every time I turn on DIY Vidock, all my other devices (Usb, mouse, wifi) all stop working. The vidock boot menu detects the 5870, but I don't think Windows does. Sometimes after I turn it on I get a BSoD saying "Bugcode USB Error"

HELP PLEASE!
Thanks

Well, after hours of testing and configuring, I'm still unable to get it to work. I have used the following scripts to a NEAR success.

It's unnecessary to do 32-bit allocation. Just install the Optimus driver which has support for your 36-bit PCI allocation of both your G320M and GTX460, standby, attach GTX460, resume. Likely PNPs and away you go. If not, just boot DIY ViDock Setup 1.x and do 36-bit PCI allocation only on the GTX460, power off the GTX460, chainload Win7, standby, attach GTX460, resume. You'd be up and running in < 10mins.

Flaunt disabled unneeded devices like the fingerprint scanner and USB ones on his M1330 to get rid of this problem.

119.9fps in dmc4 nando! Made me overvolt my 460 to get 860 core, and with that and 12% cpu/pci-e OC I still couldn't beat you ..

If I knew what the 4 exact wires were for the pci-e signals, I might be able to make it work if I could just focus on those. So far I have only ruled out 7 or the 19 wires. I wish I anticipated this and just bought the very short HWtools cables

Yes.. 119.9 is a pretty decent result. Oh and the OCed 3dmarkvantage results were >12k and >13k with x2 1.0 x1 1.0-Optimus. Optimus on compatible systems sees seriously turbocharges 3dmark/3dmarkvantage results. I'd wondering if x2 1.0 Optimus would give a OCed 15k result?

You can find the mini HDMI pinout on hwtools website. Just look at a schematic of a PMN3, EC2C, PE4L or PE4H.

In few days I'm going to buy GTS 450, hopefully with Optimus. I'm wondering about an improvement in performance against 5750.

Your E4300's 4500MHD will unlock Optimus to full capability. GTS450 benchmarks at ~30% slower than a GTX460, but it's 105W TDP means can be made small and portable with a 12V/120W AC adapter. It's US$70 cheaper than the base 768MB GTX460 as well. Will be good to get some GTS450 benchmarks to see how it does on x1 1.0 Optimus.

I love having experts around. I'm gonna try those solutions shortly.

Hello! So I am trying to discover whether I can use DIY ViDock or not, or more if it's a good idea, and how to go about doing that. I guess first some basic specs are:
Dell Inspiron N5010 laptop
Win7 64 bit
Intel Core i3 CPU, 2.27ghz
4 GB DDR3 RAM
283 GB hard drive
Intel HD Graphics

Please let me know!

Oh and I forgot to say that my main goal is to play starcraft 2 better than all low settings...

Alright so now, the computer recognizes the 5870, but it still won't switch to it. Under the ATI icon in the bottom right toolbar, I can right click it and it shows 3 options for a 5870. However, when I actually click "external monitor" nothing happens. The 5870 shows up @ devices + printers on the very bottom under "Unspecified". Help anyone?

Mechanism 1-
I already had optimus installed so I was able to test this in a few seconds. Standby / Attach does make the GTX460 appear in device manager with no problem. However, USB is no longer functional and it says "there is no driver for this device.".
I was able to get the standby trick to work twice (I'm sure by luck) and both GPUs were fully functional. (although an MS miniport was broken)

Mechanism 2-
Every attempt to do a 36 compaction resulted in express port 8 having error code 12. (I tried many variations of 36 bit compaction) [I can almost say every compaction I've tried ends in express port 8 being an error 12]

Fiddling 1-
I read somewhere in here about someone else having USB issues after the standby, so I decided to disable one of my express ports (5) before chainloading. This seemed to work 30% of the time. (disable the port, load win7, standby, poweron, resume) But this result was the same as the few luck tries in Mechanism 1. That is: USB breaks and a virtual miniport no longer functions, but both GPUs are live.

It seems as if the windows reallocation is hit/miss for my setup. Since I've seen it functional more than a few times, I'm sure there must be some configuration I can do to make it consistent.

Any ideas?

Does the PE3A work for DIY Vidock??
PE3A ( PCI-Express or USB 3.0 to ExpressCard Adapter )
it is new release and seems like supporting PCIe 2.0...
