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.
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") 188.8.131.52.37 (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?
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.

Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
- MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
- Razer X Core
- Apple TB3 to TB2 Adapter
- TB2 Cable (Cable Matters)
- 23inch AOC External Monitor
I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.
Well I am back, sort of.
Reminder of Stats
*Alienware M17x R4 (bought June 2012) w/ Intel i7 3720QM@2.6ghz (Ivy Bridge) including the igpu Intel 4000 HD series
8GB Ram, 17 Inch, SoundBlaster software only Recon 3DI, and the normal stuff that comes with it
*Graphics Card: Originally shipped 660m, upgraded to 7970m, 7970m died early, with community help moved to MSI 4GB 680M (flashed to Dell thanks to @svl7) and installed I think 314.xx drivers with help from many (sorry can't remember everyone but notable was @J95), was running 7970m in whatever they called their hybrid drivers, the 680m is run in Optimus)
*OS: Windows 7 64bit Service Pack 1
*Storage: Msata 1tb Samsung 850 Evo, 2 Hitachi 1TB 7200 rpm 2.5" drives (yes I used all 3 GB or will)
So what will you read. What got me started on this project and then using all the resources on the net, from @J95 and legions of others I owe all credit for the project too. Please note I take no credit, take no rights, this is simply something to help others out based on working with what has already been laid down for us. Installing the latest Nvidia 417.67 mobile/notebook drivers for a 680m for Windows 7 Service Pack 1 on Alienware M17x R4
When I got things up and running back in 2016/2017 with the noted people above I saw a new driver and with the STO game having a driver issue I upgraded to it. Now I didn't notice anything wrong, the game worked and so paid no attention. When I started to get unable to eject 680m error messages I thought great who got this, ejecting a gpu, wrong. I then tried the uninstall Intel, Nvidia, use DDU in Safe Mode, disable AV/Firewall, disable driver enforcement, etc then reinstall intel, nvidia (removing certain folders) with the modified inf but now the game said it couldn't find any feature set and wouldn't let me play. Finally removing the Nvidia drivers allowed at least the iGPU to run the game. Used Unigine Heaven 4.0 to encounter more errors with Nvidia.
I moved back to my msata install of windows 7 that I haven't had a chance to work on since 2017 (i know pathetic) that only had system drivers, expired Norton, and not yet registered/activation. Seems fine. Tried to run Heaven, same error. Well after 3 days of trying to duplicate what I had been instructed to do, I finally sat down with a nice big bottle of Fiji Water (courtesy of lovely lady at the Oscars in almost every background pic) and decided I was determined to fix things. I downloaded the 419.67, copied the nv_dispi.inf & nvdmi.inf to get to work. After reading the content and using comparisons once again from the noted individuals and the legions of other, I had them modified and decided to give it a try on the clean win 7 install from 2 years ago. After the uninstall, ddu, deleting folders, copying mod. inf to their directory (also included the change to setup.cfg - credit once again goes to individuals like @J95), gyrxiur, DeathAngel , creator of Notepad++, sora and many others) I was able to launch the Heaven 4.0 Benchmark. So I am assuming that I have the new 419.67 working on my system. I did a benchmark of the 680m in 419.67 with unigine Heaven 4 to go with the files I am posting. Please note the bios was provided by I believe @svl7 (sorry if I got wrong person) and no overclocking of it other than what the changed vbios did.
I am attaching below the following:
Nvidia 419.67 modified inf and config - nvdmi.inf, nv_dispi.inf, setup.cfg (no credit to me all credit belongs to others)
The Unigine benchmark results (txt file).
Now the shortened legalize warning
Please remember you are to take all risk when using modified inf files, I take no responsibility (no virus or other dildrus included) if they don't work with your GPU. The usual.
This was tested and used on Alienware M17x R4 running the last bios they released A12 or A13 and so it the system bios is not modified at all, the card is a MSI 680m 4Gb flashed vbios to Dell 680m 4GB, and installed in Windows 7 64bit Service Pack 1. Hopefully if you have only a different card you can make any minor adjustments you need to.
Please let me know how they work. I will also be reporting back on the reinstall on my other laptop install I use to play Neverwinter/ Star Trek Online - was suppose to be a temp solution till new install was finished, and if they worked on it as well.
