Replacing a K4000M with a K4100M on a 8770w, but i had gotten problems

Recommended Posts

Well, after my ZBook died because of faulty bios (hardware related) and it had a K4100M (OC) with HP vBios,
i wanted it to be on my old 8770w, but it just gave me no screen output (laptop screen) only on VGA (didn't test on DP cuz i got no DP Monitor nor cable) and i liked how the K4100M had better performance than the K4000M (Well the oc made the bandwidth go from the original 102 GB/s, to 200 GB/s [Not stable at all in some games like Rust, or Heavy iray rendering] vs the K4000M 89 GB/s [BTW I couldn't find any SAFE way to oc it]
So I decided to make some research and testing,,

Long ago before I started searching on how to do this change of gpu i found out that people had 980m in their 8770w and also k5100m without any errors, just by modifying the drivers, i tried so and failed.

This is my laptop Specs:

HP EliteBook 8770w
Quadro K4000M
Intel i7 3820mq
2x500GB WD Blue (Only ones i had around empty in my inventory)
20GB of ram (I know its not "correct" but i used 3x4GB and 1x8GB RAM sticks)
1080p Screen Non-Dreamcolor

Windows 10 Pro 64 Bits - Creators Update (Btw im in Insider Program)

Notes:
This laptop has no Optimus support as far as i know,
I havent tested on more vbios, only on 1 OC Dell Vbios
I didnt test video output on DP, Beacuse i have no DP Monitor nor a cable, and i dont need it, at all.
The laptop didnt give any video on integrated screen, only on vga with OC HP vbios and aswell Original (Backed up) vbios, only with the Dell vbios made successful output to laptop screen.

There was video going on at VGA without nvidia drivers, if i installed the drivers the screen had artifacts like random colors then the laptop freezes and shutdowns with errors, even with dell vbios.
GPU temp was higher than usual, even when it wasn't on high load.
I was able to run Besiege at 5 fps without a driver (Only with Microsoft Display adapter).


So by some hours of testing this were the results:

I replaced the K4000M with the K4100M,
I used windows recovery thing at startup (since the nVidia drivers from K4000M bugged the hell out the screen output) then I selected the CMD option, did cd to the folder where i had nvflash, flashed my gpu from there, with a OCed DELL vbios, (link), and then restarted my laptop,

I was so excited because i made it make video output through the laptop screen, and then i loaded windows normally and the drivers started to bug the screen and then windows crashed after 4m every time i logged to windows (even without logging in), it said Video tcp failure (or something) and Watchdog_DPC_violation,

So i used a fresh windows install (from a HDD i had around), it did give 1080p video output to laptop screen and i didnt test anything at all, so then installed Normal Nvidia drivers (from nvidia not hp neither dell) and then it started to bug again,

And well, Then i tried using Ubuntu (17) and the screen give 1080p output without problems, i was going to install nvidia drivers but it was too difficult for the short time i had to test, so i didn't finished up testing with Ubuntu,

As some dude told me at other forums that it might be an Optimus driver bug or something, so later on ill try testing with modified drivers.
Also the GPU temp was high, i didn't check out the temp, but the laptop was too hot for normal use and used too much battery life (i found out when i was playing around with Ubuntu at my couch).

And months before, I found out that in Nvidia page it said that the K4100M worked only on Haswell Generation (4th gen), and not Ivy Bridge,
now it says that supports Shark Bay, which is kinda new, since that "option" wasn't there before.

This is what ill do next time i make another test:

I'll use another vbios a not OC one, just a normal one,
Modify nVidia Drivers to try removing optimus (if posible)
Finish testing up in Ubuntu
Try to use older Drivers to see if anything happens.
Post the pics of the Artifacts and a video of besiege running with Default video Driver

Hi!

If your laptop from HP vendor, then why you use vbios from Dell?

Well, i heard on other forums that if you still have some problems with HP vbios, try using a Dell one, it will work as well, so i tried with a Dell vbios and gave me actually video output to the laptop screen, rather than just vga and DP.

 

im going to see if i can get access to a Zbook 17, and try if the K4100m is not damaged (because i had stored that card in a box like since 3 months so ill just test it around) and ill give any update.

      I have tried to update nvidia drivers of my notebook ge72vr6rf apache pro. The only drivers that works are the ones provided by the msi. The problem is that they haven't updated those since 2016 and I can't play newer games. 
       
      Some say you need to mod your 1060 drivers, which I have no idea how to some says you need to update the flags in ini files. So please help me
       
      Thanks for your time.

      hello everyone, I have a MSI GT683R with a dying (pretty much dead actually) GTX560M in it.
       
      I am looking to upgrade it to a new GPU, I have found a AMD Firepro M6100. (I first wanted to upgrade to a GTX970M, but that's too expensive for now... and corona is also making things difficult) I have already ordered a second heatsink to modify because I didn't want to modify the original heatsink it came with.
       
      But, my question is. Does it even work in this system? I have heard of people getting it to work in the barebone variant of this system. But I am not sure if it would work in the 'fully loaded' variant.
       
      Also, my games are mostly RAM/CPU dependent and I am looking for a little extra power in this system. I have found a I7-2860qm and I want to upgrade to 32GB of RAM, is it possible on this system? the sticker says 'max. 16GB of RAM' But I have feeling it says that due to the limitation of the cpu that's already on this system (I7-2630QM, 16GB RAM max.)

      Following the release of NVIDIAs new 436.02 driver which I mentioned in an earlier article here, I've decided to make a quick and dirty video showing off NVIDIAs new Sharpen filter which is part of their Game Filter feature. It works with the most popular APIs including DX 9, 11, 12 and Vulkan and can be set on a per-game basis with granular settings of 0-100 unlike AMDs RIS which is limited to Navi and lacks DX 11 support.
