Setup 1.30 Discussion

Recommended Posts

The latest test version of setup 1.3 failed to chainload. Don't know why... :) I hate when I have to debug and I don't know where should I look.

Hi,

Desperately need your help!!!

I have Dell studio 1555 + egpu sapphire ATI R9 270 + igpu ATI Mobility Radeon HD 4570. I failed to install the driver. My external screen is blanks. The device manager show the driver already install and no problem found.

I try to find the DNA driver, but nothing match with this new card R9 270.

The hardware is working fine, as I already try using lenovo T520 with Intel graphic inside.

Any idea?

Hi,

I'm not sure if me question is right here or if I should have started a new thread. Does anybody have expirence with the new PE4C? On bplus it looks available now (I don't know since when). I'm new to this topic and like to try it out with my Dell Vostro 3450 (with Expresscard).

PE4C has been recalled, pending some fixes. It will be released in V2.1 form.

@Arise

I know, but they're those ASUS Gsomething gamer pieces. I'd like a notebook without discrete GPU and exchangeable CPU in a small form factor with high battery life.

That's why I'm asking. I'd buy a macbook, but the CPUs are not really fast (top models cost waaaaay too much). So there actually is nothing left.

I'm of the same opinion. There is no business grade, quad-core, thin and affordable notebook with a TB port. Something like a Dell M3800 but with TB port. Closest is a 15" MBP which is hardly affordable.

I acquired a 14" Dell E6440 expecting it would allow a x2 2.0 config, but alas no. I detail why and point out a 14" Dell E6430 as a possible x2 2.0 machine at http://forum.techinferno.com/dell-latitude-vostro-precision/6980-14-dell-latitude-e6440-owners-lounge.html#eGPU . Note too that the quad-core Haswell CPUs have worse performance than Ivy Bridge ones as detailed in http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 .

x2 2.0 hasn't been considered much so far. Reason being (1) x2 2.0 capable hardware was only just released in the form of a PE4C V2 by BPlus. Though I found that PE4H 2.4 was capable of a Gen2 link only with an AMD card (not NVidia) when using the newer PCIEMM-060B cable (2) configuring x2 2.0 requires obtaining a bios dump, reprogramming it using the Intel ME firmware tools and flashing it back. That's because Intel have locked down the port width configuration as of the Series-6 chipset. Prior to that it was possible to modify the link width by Setup 1.x software. Obtaining a FW dump on a Dell system requires bridging some pins on the audio codec chip. There plenty of margin to brick your notebook in attempting this.

I'd suggest hold onto your 12.5" 2570P and see what Broadwell systems released later this year bring. Bang-per-buck and bang-per-cm^3, an i7-quad upgraded 2570P is untouchable.

Hello,

I bought P4EL and can't make it work..

The GPU I got is HD4830, my laptop is Lenovo T420, and I am connecting the PE4L with the mini PCI-E.

The problem is that the GPU isn't detected :[

What can be the problem? the GPU is too old :o?

Can the PSU be the reason? I am using some old 400W PSU..

In case you guys wanted to know even though this laptop is limited to TB1 this is coming out soon. It stands to get TB2 at practically the same price as the Firmtek Thundertek. This one can run a Thunderbolt2 (TB2) 16Gbps eGPU or a Thunderbolt1 (TB1) 10Gbps eGPU. See TB2 and TB1 equipped notebooks at http://forum.techinferno.com/diy-e-gpu-projects/4109-egpu-candidate-system-list.html#post57511 .

Although the device is advertised as Thunderbolt 2, the specs indicate that the device is limited to only 5Gbps, which is only have the performance of Thunderbolt 1. So I think you're better off bying a Sonnet Echo Express with e BPlus adapter or something similar.

Hi,

is it right that this software is bundled with the PE4L v2.1b so I don't need to pay for it when I buy the PE4L? DIY eGPU Setup 1.x Help says so, but the page looks a bit outdated. Couldn't find an answer here in the forums either.

Brom

There is no software bundling with any PE4L 2.1b or any other BPlus adapters. BPlus so far unwilling to provide a one-stop-shop for the hardware and software combo. There was a time prior to June-2013 when Harmonic Inversion (HIT) in the US was given permission to bundle the software with their adapters. HIT are no longer operating. They closed up after doing a runner with funds earmarked for eGPU community use: http://forum.techinferno.com/diy-e-gpu-projects/3793-summary-dealing-hits-abandoned-egpu-commitments-%5Bcustomer-thread%5D.html#post53541

Hi guys,

I'm thinking about buying a new Lenovo ThinkPad L540 (i7 4600M, 4+4GB RAM) and I'd like to know whether I understood everything about eGPU setup for it well.

As it is a laptop with ExpressCard and 4th gen. IntelCPU It should be suitable for x1.2opt (NVidia) / x1.2 opt (AMD) solutions.

For that I'll need a power supply (standard one from a PC will work) and a ExpressCard -> PCIExpress adapter. Given only one port (EC) the best option is EXP GDC (PE4L 2.1b would also work).

Then, if I'm ok with using the external display only, it should work without any software modifications (other than installing official NVidia / AMD drivers) -> just plug in, boot up, play games. With WIndows 8.1 I should not have any problems related to error 12 (or address space in general).

//BTW: Could anyone explain to me the what 'TOLUD' is? I understand that it is somehow related to address space (e.g. the bigger the less space is free for eGPU) but couldn't find proper explanation (and I'm sure I'm not the only one).

Considering NVidia vs AMD dilemma. NVidia cards should be way faster in DX9 (thanks to Optimus compression) but pretty much the same in DX10/11/?12. The difference will be even smaller (almost unnoticeable) when using an external LCD (which I plan on using). On DX10+ and external display the AMD cards should actually be a bit faster (could anyone estimate by how many percent?).

Considering the 'low bandwidth performance loss', with GTX560 / GTX660 and x1.2opt (or corresponding AMD card and x1.2) I should be able to get circa 70 % of performance (therefore FPS) I'd get on PCI-E 16x desktop PC?

Thanks :).

The current cheapest way for Thunderbolt 2 is to use Akiti​o Thun​der2P​CIe Box

Just 201$

- - - Updated - - -

Nando4,

I am wondering why does PCIe slot in the card requires power? The graphics card itself is powered by 6/8 pins from the PSU, but I have seen 16x risers with Molex power too!

Dose this give the same performance?

This looks great! Is this an Akitio Thunder2 board? I'm really tempted with such an affordable TB2 solution.

Do you get the full 20Gbit/s with it?

cheers
