Hi all,

 

I'm looking to sell a PE4L V2.1b (Expresscard Version) and GTX750. I have used them both reliably on my Thinkpad X230t, achieving x1.2Opt and able to run pretty much any game decently well, for the past year without any issues. This setup works great as a portable setup since the GTX750 doesn't require external power. I recently bought a desktop so I have no further need for them. Here is a link to the graphics card. I'm looking to sell the PE4L for $60 (got it for $70) and the GTX750 for $70 (got it for $90) or $120 for both, with a flat rate of $5 for shipping. Here's a picture of my previous setup that I was running off the eGPU. If you have any questions or want more pictures of the parts, please PM me! 

 

Thanks!

Nice to meet you. I bought a lenovo thinkpad t420 yesterday on ebay and I want to install an egpu on it. So maybe you can help me with some advice because you have a very similar PC. :sorcerer: It is worth it or not, based on your experience?

The experience was worth it for me. I was able to have an almost plug and play experience with the setup and had a portable setup (the laptop itself) and was able to use more gpu intensive programs such as CAD when plugged into the eGPU. This allowed me to have a great combination of portability and power when I needed either. Thinkpads typically are very easy to setup with the exception of the 8GB memory limit due to memory configurations on some BIOS's. I'm not quite sure if that's still an issue with that memory configuration.

 

I would like to bring this discussion about price into PMs, but you don't have enough posts to PM yet...

Yes I cant PM because im new in the forum. I started my research on egpu's a couple of weeks ago but after thinking about it I was like :hyper:whatever lets do it. So I bought the lenovo and now im searching for the rest. So your setup doesnt needs additional power supply? Just plug the expresscard to the laptop and the gpu to the adapter and thats it? You can use laptop display for gaming or only external display?

It only requires a power supply for the PE4L board since the GTX750 is powered through the PCIe slot. It can be powered by either an ATX power supply or laptop power supply (12v barrel connector I think), the second also requires a USB to USB cable in order to power the board. The whole system will run at x1.2Opt, but slightly worse performance on the internal display since nVidia will be using Optimus to run that display. On the external display, I was able to run Battlefield 4 at medium settings with consistent 60 fps. Just one thing to watch out for is the USB bus usage -- I had some issues when I had too many USB devices plugged in and would get BSODs occasionally.

I'm not sure what the post count is for PMs, but I would prefer to do that. Or we can communicate over email if you have one I can contact you at.

      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.

      Hello everyone,
      some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
      Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
      I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W 
      Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
      If anybody tried something like that on any laptop model, or knows the matter, I'd like to know

      After spending significant time and effort to obtain "DC" screen for 8770w (which is essentially a regular IPS panel with fancy board that converts 8bpc LVDS to 10bpc DP), I have finally got and installed one. All works great, except of the one problem...

      It has pretty bad banding / posterization in lower shadows. I have tried profiling it in different modes (full range, sRGB, rec709) - issue persists, and it indeed shows only in the lowest part of the characteristic curve. Mids and highlights are represented fine and show low deviation from reference values.

      GPU is HP K4000M, Nvidia drivers installed "as it is", video-card is identified without a hitch.
      Banding was not present with the original TN panel using the same GPU.
       
      While checking a software side, I have noticed that Win10 has bit depth set to 8-bit...
       

       
      My initial reaction was, - "Easy, let's change it in `nvidia-settings` and we're all set":

      ...but that would be too easy, right? After selecting 10bpc and clicking "Apply" screen went off and back on, only to show that depth stayed at 8bpc. Repeating the above few times yielded exactly the same result and I'm not in a hurry to meet a cliched (and laymen) definition of insanity.
       
      Let's check GPU-Z. So far so good, nothing unusual. Notice the highlighted BIOS version and subvendor string:
       
      Time to delve into other tabs. We are running WDDDM v2.4 which supports GPU dithering, but hey... BIOS version has changed!
       
      Briefly back to `nvidia-settings` to check what is reported by vendor's own utility:

       
      So far, we have two strings for BIOS version:
      80.04.5A.00.02 (let's call it an "A") 80.4.33.0.37 (let's call it a "B")  
      Notice how 2nd one seems to not follow hexademical notation. Lastly, "NVIDIA BIOS" drop-down, reports "A" version:
       
      ...and monitor section which confirms that rig is indeed capable of 10bpc, but currently running at mere 8bpc:

       
      Windows "Adapter settings", reports version "B". It's 2019, diversity is a must.

       
      "NVidia inspector" is of the same opinion:

       
      Now, let's use some seriously legit tools and check-in exported BIOS file in `nvflash`:

       
      Here we have two three interesting findings:
      Reported vendor is Dell, not an HP. See this link for details. BIOS version is back to "A". Have I already mentioned diversity? MXM module uses MX25L2005 flash storage in WSON-8 packaging. If things go real nasty, we should be able to rescue a patient via Pomona clip and external programmer.  
      Loading the same file in "Kepler BIOS tweaker" confirms the facts:

       
      EDID settings, courtesy of NVidia Control Panel. Hex dump can be found at the bottom of this post.
      ...Shall I be worried about "60.02Hz" refresh rate?
       
      To summarize:
      Why two different BIOS versions are reported? Anything to do with UEFI (e.g. HP is sideloading its own during boot)?.. Why two different vendors reported? As far as I remember, this is branded HP GPU. Where to get "clean" BIOS of K4000M for future experiments? Ideally from 8770w equipped with "DreamColor" panel from a factory.
