BPlus PE4C V3/V2 discussion

Recommended Posts

You can't do the swap that you propose because the mPCIe adapter only wires through USB.

I'm not sure what you mean. If you look at the components in both the links I posted, they both use USB. The main challenge would be finding an mPCIe adapter that uses USB 3.0.

From my perspective, it's worth paying more from the get go to get better Gen2 signalling.

Yes, if I'm going to end up buying it eventually anyway there's no reason to waste money on cheaper hardware that may fail. I'm just wondering if it would be a better idea to put the money toward buying a whole new computer instead of rigging a card to my laptop. I will have to see what my financial situation ends up being in a month or so.

Your mPCIe board wires through USB (pins 36/38). That's not going to help a PCIe eGPU. You want it to wire through PCIe (pins 23, 25, 31,33) + REFCLK (11, 13).

Tech Inferno Fan? Do you happen to know what makes the system Gen2 or Gen3 capable? I'm curious, could the 2570p make use of that 8Gb/s on tap?

All of Intel's current chipsets have their southbridge ports (mPCIe/EC) specced to Gen2. Only their Northbridge ports that hosts dGPUs are Gen3. So no, a 2570P cannot run 8Gbps Gen3 nor can any other current notebook's EC/mPCIe slot.

BPlus advertise the adapter as Gen3 compliant moreso for the HP060A adapter. That's a x1 PCIe card that slots into desktop systems allowing a video card to be hosted externally. Recent desktop systems have Gen3 PCIe slots.

What if we soldered traces from the northbridge to the expresscard connector? Or is it too unlikely to maintain signal quality with such a hackjob?

Thread discussing that idea is at http://forum.techinferno.com/general-notebook-discussions/10100-help-request-adding-pciex16-port-laptop-soldering.html#post134686 . You'd want to first make sure the dGPU port is unlocked and can be enabled whether that be with the factory bios or with a modified bios. If it's locked and can't be enabled then there's no point in creating the electrical link for it.

PE4L 2.1b > PE4C 2.1 > EXP GDC > PE4H 2.4

Do I read this from the left or right, on what egpu chipset is better?

There is no different in speed between mPCIe and expresscard (EC). As strange as it may sound, I actually found mPCIe to give a better Gen2 signal than EC when testing on a 2570P Elitebook and a more flakey adapter. REF: http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-142.html#post55765

I understand your concern about pricing. What I can say is some ppl have posted no issues with their EXP GDC adapter. Others, inc myself, have had issues with both EXP GDC and PE4C. My conclusion was that for Gen2:

PE4L 2.1b > PE4C 2.1 > EXP GDC > PE4H 2.4

PE4C 3.0 uses the same cabling as PE4L 2.1b and has the same Gen3 compliance. Means that it's the best adapter to get for cleanest Gen2 signal? It comes down to whether you are prepared to risk the cheaper adapter and if affected, either downgrade the link with Setup 1.30 software to Gen1 or then payup to get a better Gen2 adapter.

From my perspective, it's worth paying more from the get go to get better Gen2 signalling.

Though I can see for mPCIe users with more cumbersome access may want a socketted connector. Just a shame it's on the eGPU adapter and not the mPCIe end (though HDMI is a bit big for that!).

i wonder when EXP GDC have Gen3?? I prefer EXP GDC than others eGPU :)

And is it possilbe eGPU SLI/CF in one adapter

So realistically, as much as I'd like to have the most recent variation, I'd likely see no benefit getting a V3 (when they're back in stock :-\ ) versus a V2.1, when running with my 2012 15" MBP (with Nvidia 650M) and Thunderbolt 1? I've already got the Sonnet Echo Expresscard dock for video data management purposes, so I'm deciding to go that route.

I'm going to wait for Thunderbolt 3 to start showing up in laptops, and the various companies' desktop GPU chasis to be released likely next year, before I spend the big bucks and invest in a more powerful eGPU rig.

Guys is there anyone using PE4C v3.0 adapter? Im just curious if it works correctly, because it powers on automaticly with your laptop, there seems to be no on/off switch for it.

Hi,

Yeah I'm curious too. I want to knew if PE4C v3 is realy better then PE4C v2 with real experience.

I checked the Bplus web site to buy PE4C v3 to test it and compare it to EXP GDC but it's sold out :/ I contacted Bplus but no response yet :/

Do anyone gave any informations ?

Thx

Hey, I have good news. The PE4C v3 is released and just ordered one with adapter for 90$ (shipping included). Few days before I ordered the EXP GDC from beast to compare them and keep the best one and sell the other. I'll share results if I can.

Here the 2 mails I've recieved form bplus :

Hello Sir,

Please tell me when the PE4C V3.0 will be available ? And how much time will it take to be shipped to France ?

1. PE4C V3.0 will release end June,

2. We use DHL to shipping, usually it will take 3~4days.

3.

If you have any more question,

Please feel free to contact us,

Thanks again

BR

Derek

Hi Sir,

You may order on our web shop now. Delivery day will be 3-4 days ship to France depend on each global express company.

Best Regards,

Lain

According to Roger from BPlus PE4C v2.1 is x2 2.0 capable, I know some of you guys are trying to make it work, any success yet?

(Thanks Mousty, it wasn't in stock yesterday, but it is now.)

On the site they said

PE4C V3.0 is PCIe 1-Lane 8.0Gbps bandwidth limit passive adapter in compliance with Expresscard 3.0 specification.

But in the Installation Guide (pdf file), they said

PE4C V3.0 is PCIe 1-Lane 5.0Gbps bandwidth limit passive adapter in compliance with Expresscard 2.0 specification.

So which is correct?

PE4C V3.0 has the same soldered cabling as PE4L 2.1b. They are both rated as PCIe 3.0 8Gbps compliant. However, notebooks currently have only PCIe 2.0 5Gbps mPCIe or expresscard slots limiting their performance.

You'd only be running PCIe 3.0 8GBps if attaching a video card to a desktop system using the x1 slot adapter (PE4C-HP060A 3.0).

Thanks Tech Inferno Fan, I've just read your #104 post. Now I understand the reason why. :)

Hello everyone.

I have a question about the bplus website or the hwtools.net for ordering a kit :

I don't trust this site because they ask for my paypal information to pay before asking anything else via the web-shop, like my adress, name, etc.

Maybe they will ask that just after but I wanna be sure. Anybody recently order something from them using these sites ?

Nice idea, but I'm living in France and they don't seem to be able to ship this product here :/

I think I will just use the hwtools.net website. Thanks for you advice though.

Can anyone clarify what the delay switch does? I have a PE4c v3.0 and it seems to affect whether or not the the EGPU will even turn on or run.

Hello everyone, I have some questions about setting up a Thinkpad X220, r7 370 eGPU with PE4C V3.0 EC. My system comes with win7/64, 8gb, i7-2620m, and Samsung evo SSD(not sure if these matter). I have the AMD graphics card set up properly with PE4C. System is able to detect the card and installed windows drivers. I rebooted, installed MSI graphics drivers, then rebooted again. Now the system shows the card has a code 12 error, where every other X220 users that I've read up about doesn't encounter this issue. Any ideas what's gone wrong, and how can I possibly fix this problem?

Thanks in advance!

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?

      Hi,
      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
       
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

       
      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
       
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
       
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

       
      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
       
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
       
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
       
      1) laptop on table, playing GTA V 1080p

       
      - first minute (GPU core 1045MHz)

       
      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

       
      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
       
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

       
       
      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
       
      Greetings!
       
      I will describe next step when I get all stuff I need!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.

      Hello!
       
      I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
       
      thanks.

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.
