I don't get it

At least we can hope that other laptop manufacturers will speed up their efforts to bring thunderbolt to their product line ups. This will mean less prices. I just hope we get very simple solutions with great performance. Can't wait to be free of desktops for gaming needs. Gaming laptops are a pain.

@xtraman122: considering that the culprit of the failure in negotiating PCI Gen 2.0 is the connector, i think the PE4L inside the Vidock is able to handle it (due the cables are soldered to the PCBs). The PE4H sold now can only handle PCI Gen 1.0 for the same cause,

Interesting, I figured my setup wasn't actually getting x1.2 peformance though. What are people currently using for connection methods to get x1.2 performance if it isn't the adapter limiting it?

Except Nando (that modded a PE3A) and another guy who i forgot the name (that modded the PCB too) ,there are no other results of people using a PCI gen 2.0 adapter. Once BPlus will release the newer adapter (AIO cable + connector on PE4L 2.0 / PE4H 3.0) we shall see many more experiences and benchmarks (mine too :P)

Gotcha, wait it out it is then. In the meantime I'll plan out the process of fitting one of them into my ViDock enclosure (and officially make it NOT a ViDock anymore) and work on setting up my 360 power supply.

A ViDock4+ is supposed to already be pci-e 2.0 capable according to the pre-sales product info. Can confirm if you get pci-e 2.0 speed by ensuring you haven't set Gen1 speed in the bios or using Setup 1.x (iport g1), then run GPU-Z. It will show pci-e 2.0 speed like this in the first few secs after you run GPUz as it puts the eGPU under load. Once the eGPU goes into power saving mode it will revert back to pci-e 1.x speed like this. SOURCE: DIY eGPU implementation: i5-2540M 2.6 12.5" HP 2560P + NVidia GTX560Ti @x1.2Opt.

If the VD4+ isn't running at pci-e 2.0 speed then suggest seek a refund for misleading advertising.

Edit- nevermind! Got it figured out

I am considering putting together an EGPU for my Lenovo T400, but would like it to be as simple as possible. This is surely a newbie questions, but if an expresscard slot is rated at 75W, why is any additional power required for the GT 430 (49 W)?

---
US$125 12V/72W GT430-1GB eGPU Portable setup (GT430=49W TDP)

US$65-ground_shipped PE4L + US$50 GT430-1GB+ US$10 12V/72W AC adapter = US$125. Optional: use a $15 12V/120W adapter instead.
---

Could I just buy the GT 430, plug it into the PE4L (LEAVE OUT the AC adapter), and plug the combo into expresscard slot? My laptop is almost always plugged into the wall so battery life is not an issue for me.



If not, another question...

Is a PSU necessary? It doesn't seem to be in the following setup...

----
US$160 12V/120W GTS450-1GB eGPU Portable setup (GTS450=106W TDP)

US$65-ground_shipped PE4L + US$70 GTS450-1GB+ US$15 12V/120W AC adapter + US$5 molex splitter/gender changer + US$2 pci-e to molex (male) adapter = US$160. Run a jumper lead from the floppy molex to the pci-e connector as shown here to split the power.
----

Sadly the links to the implementation of this setup are broken, and other examples that I found all used PSUs. As a matter of fact one of them didn't work because his PSU was poor.

So is a PSU necessary for the GTS450?

Hi,

This is my first post and would like a little advice on building my DIY eGPU as im a bit of a noob.

I kind of have an idea how to go about installing it but would just like some clarification.

think i will need to do X1 setup as i want to keep my wifi

My Laptop Specs:

HP DV6-2113sa
Mobile DualCore AMD Turion II Ultra M620, 2500 MHz (12.5 x 200)
4GB RAM
Windows 7 Ultimate

I have ordered a ATI Radeon XFX HD 5870 (XXX Edition) , PE4H V2.4A + EC2C + 30cm-HDMI + SPB087 ExpressCard to PCI-E Adapter

I still need to order my PSU but unsure about what type and how many watts i will need.

I have been looking at getting the Corsair CX-500 V2 however i was wondering if i would be able to run this from a PSU with a lower wattage to save on costs? if so, what would you guys recommend?

if anybody could give me some simple steps to get this working on my system, that would be great.

also what kidn of framerates would i expect to get from say: BF3, Skyrim , Unreal tournament 3, Crysis 2?

i will be more than happy to post some benchmarks and pics once it is setup

thanks in advance
