 Hi there,just ordered the adapter,still waiting to arrive but looking at the picture in the website and in my laptop i figure it out that those legs will be too long to fit there(see picture).My question is is it going to be ok if i cut the part shown on the picture without damaging something? Any help or advise will be appreciated. Tnank you !!!!!

It’s designed so that those pieces can just be snapped off; no need to cut anything.

Another question,this time is about the power supply.So i’ve been looking at the requirements on certain video cards and that’s what is says for example: Power Usage 120W Recommended Power Supply 600W.Considering the fact that there will be no other hardware involved,just the JPU,do i still have to get the 600W one or i can go lower,like let’s say 500W?

You need the TDP of the GPU plus some overhead, just to be safe. TDP is just what the IC itself can safely dissipate, not the total power consumption of the card, which will be a bit higher.

 

120W is 10A at 12V. 15A would probably be enough. Even a 400W supply can deliver that.

 

For a 120W card the Dell DA-2 is the cleanest and cheapest solution though. You can buy them used for $11 shipped on ebay (in the US anyway).

Plastixx to the rescue again :-),thanks man,i was thinking to go with something like this  https://www.amazon.com/EVGA-Warranty-Power-Supply-100-N1-0400-L1/dp/B00LV8TZAG/ref=sr_1_2?s=pc&ie=UTF8&qid=1483288490&sr=1-2&keywords=power+supply&refinements=p_n_feature_keywords_two_browse-bin%3A6906983011%2Cp_36%3A1253504011 which is much cheaper then the 600W one,but you pretty much answer my question.Thanks again and HAPPY NEW YEAR  🙂

That supply has a 30A 12V rail; way more than enough…

Hi, I have successfully setup egpu (750ti) with hp2570p via pe4c 3.0. However the framerates is unstable with some games like call of duty 3, merely 20 at 720p (internal screen), meanwhile I get 40 with batman arkham city.

I dont get the logic. Because Gpuz show that I just use ~85% bus interface load, the GPU load is 100% so no bottleneck here. 750ti can drive 1080p at medium, so no problem with 720p.

Can you guys suggest me a fix? I like to play with the laptop screen. @Nando4

The internal monitor will always result in a performance hit. If you are using an Expresscard/mPCIe solution, you should be using an external monitor if at all possible.

@egpuer, if you want better NVidia Optimus accelerated internal LCD performance on your expresscard link:

1. Run a Gen2 link, though it will depend a lot on your eGPU adapter. PE4C 3.0 or PE4L 2.1b with soldered cable most likely to provide reliable Gen2 operation.

2. limit FPS to match your internal LCDs 60Hz. Having redundant FPS greater than 60hz impinges on the narrow x1 link bandwidth. Do this with NVidia Inspector’s Frame Rate Limiter V2 and vsync.

3. Decrease your Display properties color depth from 32-bit to 16-bit, and resolution

4. Perform other in-game optimization

 

yukikaze’s suggestion of using an external LCD will however net you better gains.

Hi nando, I forgot to mention that I have successfully setup gen 2 link. GPUZ confirmed that (x1 2.0)

The wierdest thing is even  the lowest settings (no everything, 800×600) Call of Duty 3 still stuck at 20fps or less. Meanwhile BM arkham city rocks at 40 fps max setting 

 

Use an external monitor make Cod works fine (40-50 fps 1080p medium)

I test the bandwidth with sandra and got the result. Pretty much the speed of x1 2.0. No ideas why the lag happen 🙁

Upload Bandwidth 0.32GB/s
 Download bandwidth 0.39GB/s

Use GPU-Z -> sensors or hwinfo64 to record then review the “GPU BUS load” NVidia parameter while playing COD3 on your internal LCD.  You’ll be able to see for yourself if you are saturating the bus with internal LCD traffic, choking COD3 from being playable.

What CoD exactly are you playing? CoD 3 was a WW2 title exclusive for consoles. Apart from this all the CoD titles hate eGPUs for some reason, I’ve had massive FPS drops whenever I was aiming through a scope in CoD 2 as well as CoD Ghosts, there’s something in the engine that doesn’t work along with eGPUs limitations .

Making a stop of undetermined duration in the no-eGPU land ;-)

@nando4. Well, you’re right. The bus load is 99% even when I set 16 bit display mode 🙁 I see I have another pci e port for sd card, can I disable and link it up to make x2 2.0? Or get a better graphic card will yield better result? 

 

@Morv : I mean COD Modern Warfare 3. MW2 I can play pretty smooth, sometime it drops to 28 but not very annoying.

2570P isn’t x2 2.0 capable. Only found Dell E6430/E6530 was but requires modified firmware and x2 2.0 hardware which is now obsolete.

Only if newer GTX9xx/10xx have more efficient PCIe data transfers will they offer any improvement to your data bottleneck. If after applying previously mentioned tweaks you find are still bottlenecked and need more bandwidth then suggest a Thunderbolt notebook + eGPU or desktop system instead.

So you mean I shouldn’t upgrade to more powerful gpu like 1060 due to the bus bottleneck? It seems the problem is the game itself, I see another guy complain COD run badly on egpu 🙁

Do you know some budget portable monitor that can fit in the backpack and work with egpu? Like this   and this adapter.

TY for your support 😀

Yeah, the USB powered LCDs would be the pick to avoid needing a power brick. You do however want one that directly plugs into the eGPU to have the bandwidth sparing effect over your current internal LCD configuration. So your LCD needs DP or HDMI input. Check what google finds . . .
