so i´ll just have to click on send money to... and that´s it?

that sound´s easy

A powered PCIe riser has pins 1,2,3 on side B and pins 2,3 on side A connected to 12V. I illustrated in the picture below which side is A and which is B.

Also pin 4 on side A and pin 4 on side B are grounds. Can you do a continuity test for all these pins too?

Thank you very much

Yep. Both sides (A & 12V golden finger of PCIe riser had a correct continuity to the test point (one of the 7 holes).

Can a mod please delete this. Double post.

Hello, I bought macbook pro 13" and I would like to know what is the cheapest egpu solution in europe.

I am interested as well

Macway France also offers the Akitio Box for 260€ including taxes and shipping costs (just bought it from germany). I'll report on thursday how it works with my 2014 macbook pro retina and my radeon r9 290 gpu.

News?

The title says it all. I currently have a PE4L 1.5 EC egpu. I think I can make it an x4 setup, but M-Factors storage only sells the PM3N bundled. Please PM me if you have either the PE4H or a PM3N for sale. Thanks in advance.

I also have a Thinkpad T530 and I considering using PE4C -EC100C V2.0 for the eGPU system. The system requirements listed here: http://www.hwtools.net/PDF/PE4C%20V2.0_brief_installation.pdf says that

PE4 C v 2 .0 is PCIe 1 - Lane 5.0Gbps bandwidth limit passive adapter in compliance with Expresscard 2.0 specification.

Almost PCIe 16x video card can’t get enough memory resource are allocated. Can’t work in your laptop.

I am not so sure if this can work with T530 and what is graphic card I should get for it. Could you help?

[xigma]

Yes, PE4C 2.0 was pulled from sale. Was told there was a bug in the hardware design that triggered ait. A

AFAIK both the PE4C V2.x and EXP GDC V6 have a Dell DA-2 220W AC adapter option. That's good enough for a GTX680 or R9 270X. R9 280X requires 250W. A NVidia card is recommended for it's superiour performance over an AMD equivalent where the candidate system has an active Intel HD iGPU and a x1 1.0 or x1 2.0 PCIe link.

Could you elaborate what does triggered ait. A mean? PE4C 2.0 is still available for sale on China's Ebay site and I am considering buying one if the ait.A problem is not so serious.

[xigma]

Finally my PE4C-EC100C V2.0 is arrived!!!

Installation went fine now i'm trying to let nVidia optmus work.

In the weekend i will do some benchmarks.

From here I read that "PE4C 2.0 was pulled from sale. Was told there was a bug in the hardware design that triggered ait. A"

Any idea what is triggered here? and How does it affect PE4C 2.0 system? I am consider buying PE4C-EC100C V2.0 and I am not so sure if the aforementioned problem will cause any problems.

[Dschijn]

Sweet!

This is the safest solution right?

If we allow the TB board to draw power from the powered PCIe riser plugged into the PCIe x16 slot of the PCIe board, the molex supplying the power could potentially be overloaded with the 75W power required by the graphics card + power required by the TB board? Conversely, if we allow the PCIe board to draw the 75W power from the x4 connector via the TB card, the TB card could potentially be overloaded as well?

Good point about the safety here. To remain within PCIe 1.1 spec, we'd be passing 75W + 10W (TB power) minimum. That's a 85W minimum. At max, the TB board could draw 35W when including bus power. That then puts the upper ceiling at 120W.

To safely pass power would then need (1) PCIe riser whose molex has at least 4 input leads (2) molex concentrator connecting to *two* 4-pin molex ATX PSU leads. That is:

(Powerful, Expensive -> Power-saving, Cheap)

i7-38xxQM >> i7-37xxQM >>i7-36xxQM

You can't go wrong with the i7-3632QM quadcore mobile Ivy bridge processor for cheap, efficient power. Just make sure it's the G2 socket (rPGA) instead of the solder (BGA) type. BGA-to-PGA converted processors are also available for a much cheaper price. But once again, risk in performance drops are more common there compared to the ES/QS models of the same processor. Just hope for the best when buying or go with OEM and warranty.

Think you are referring to the 45W i7-3630QM or i7-3610QM as being the cheap quad-core Ivy Bridge options. The 35W i7-3632QM or i7-3612QM commands a price premium due to it's lower TDP.

The performance ranking being i7-3840QM > i7-3820QM > i7-3740QM > i7-3720QM > i7-3630QM > i7-3610QM. Though this is not entirely true. What will matter more will be the unique chip's real-world power dissipation where considerable variation exists. See INFO: How to choose the most efficient 45W i7-quad. There we see an example of a i7-3630QM performing the same as cheaper a i7-3610QM, betters one i7-3820QM and have an i7-3740QM outperforming higher priced options.

Unless you can cherry pick a higher-performance CPU from a number of samples I'd advise to go for a lower priced CPU.

[badbadbad]

Oh yeah. My bad. Corrected the post.

[Leaskovski]

Ok, just noticed this in the experiences thread...

Can determine how much power you require by counting the number of 6 or 8-pin PCIe connectors on your video card. The total power required to drive it will then be:

75W for the slot¹

+ 75W for each 6-pin PCIe connector

That kind of answers my question. The 670 GTX has 2 power connectors on it, and I am only running a 200W PSU. By my maths I need more power captain.

Edit:

tried another PSU that had 250W, and that didnt resolve the issues either.

In both cases, the first PSU had a 12v rail at 10A, so thats only 120W max, and the other only had 14A down the 12v rail. Reading the nVidia website, the card can draw a max of 170W, so if Im benchmarking the card, its going to try to pull the full wattage, so I need a better PSU.

[LightySnake]

Yes, PE4C 2.0 was pulled from sale. Was told there was a bug in the hardware design that triggered ait. A

new PE4C V2.1 will be released fixing those problems. I do not have a firm date when that will be. If you need something sooner rather than later then consider a EXP GDC V6. http://forum.techinferno.com/diy-e-gpu-projects/6643-exp-gdc-v6-discussion.html#post88642 . Just note the warnings about quality of the product.

AFAIK both the PE4C V2.x and EXP GDC V6 have a Dell DA-2 220W AC adapter option. That's good enough for a GTX680 or R9 270X. R9 280X requires 250W. A NVidia card is recommended for it's superiour performance over an AMD equivalent where the candidate system has an active Intel HD iGPU and a x1 1.0 or x1 2.0 PCIe link.

Maybe is a noob question, what is " ait. A" that (could be?) triggered by the PE4C V2.0.

Thank you for the reply

It's a typo: "Was told there was a bug in the hardware design that triggered ait. A" = "Was told there was a bug in the hardware design that triggered it."

[dernils]

Maybe I am wrong here, but is this how you did setup your AkiTio from your statement above?

[ATTACH=CONFIG]12342[/ATTACH]

What happen if you try this setup?

This is one of the setups I tried if akitio adapter means the PSU that comes with the box. However, it made no difference. Don't forget the thunderbolt cable to the macbook.

[euqlaog]

I just updated my earlier post:

[Leaskovski]

Ok, so after sourcing a better PSU that provides 240W on the 12v rail, I have been able to run some benchmarks properly...

Using 3D Mark's Cloud Gate test...

Without eGPU:

Graphics Score 9833

Physics Score 2441

http://www.3dmark.com/cg/2044272

With eGPU

Graphics Score 33221

Physics Score 2365

http://www.3dmark.com/cg/2049300

I would say that is a marked increase. Assetto Corsa now runs like a dream

I now just need to figure out why PhysX isn't working properly.

[gothic860]

Just to solve the Sonnet Echo problem:

Im using the Akitio TB Box at the moment, but as soon as i installed my NVidia Quadro drivers (K2100M) the 780Ti eGPU is working BUT I dont get any display on the monitor (like in my 1 post here). As soon as they are removed (DDU http://www.chip.de/downloads/Display-Driver-Uninstaller-DDU_65992840.html) and desktop drivers are installed the eGPU is working again. So i think this should also solve the problem with the Sonnet Echo.

I will try to use the desktop drivers for my Notebook GPU (it was working with my old W530) or try something else (will report here).

EDIT: Tried a lot of stuff and a lot of differtent drivers, registry edits and so on but it isnt working.

So the only way is to uninstall the NVidia drivers and only install the eGPU drivers and always disable the dGPU.

Search on the forum or on Google for the same or similar combo:

I don't think that BPlus have tested all the possible configuration and maybe the list is filled by the results from this and other community.

You have some performance loss for sure but i think that both card can work with it. Maybe you need to wait the new revision of PE4C just to be sure taht is bug free.

Like i said before you need to take some risk, for what i've understand there's not a 100% sure response.

Is a community so other people have try to let things work and then they have posted their results and thank to them now there's a lot of useful info.

Search on the forum or on Google for the same or similar combo:

DIY eGPU experiences - Page 464

eGPU can work(or at least someone have achived that), you will have performance loss compared to the same card used on a desktop PC.

Thank you i wil test it

[gomble]

i doent thougt that this is possible cool !

[tyrol_dude]

@dernils

did you allready find an egpu-solution for your mac? i just bought a mac mini and want to upgrade it for 3d stuff and gaming, booth in osx and windows. but i don´t like the solution with sonnet-express and better like even that one with the akitio or with the thundertek.

[DragonHunterz007]

Will this software fix the "swap" trick?

wit this I mean:

I can only use the egpu when I boot with my wireless card and switch the card with the pe4l when laptop is in sleep mode.

Can this software fix the issue that my laptop can not boot with the pe4l inserted?

It is like a wirelesscard is whitelisted and nothing else can use it.
