TheKillerTacos posted a topic in HP Business Class NotebooksWell, 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 together :-) As the title says I'm having a little Issue after upgrading my m6700's graphics card from the K3000M to the newer K4100M: Everything seems to work properly, but under load (i.e. 3D applications) it produces crashes / system instability after ~5-20 seconds. When I reduce the chip- and memory-clocks in MSI Afterburner as far as possible, it takes a bit longer until it crashes, but eventually it always does after a minute or so. When running on battery power (and thus even further reduced clocks) everything runs stable for arbitrarily long times. This sounds like a thermal problem to me. However, the reported GPU temperature never exceeded 65°C, which I think is OK. I guess the memory chips are not temperature monitored seperately, are they? So maybe I should replace the memory thermal pads by new ones? What I've already tried/checked/looked at: - Uninstalled previous drivers with "Display Driver Uninstaller" - Latest Nvidia Drivers can be installed properly (and also tried a few older versions) - Notebook BIOS is up to date - Tried three different Video-BIOS versions - Graphics card is not recognized by Notebook BIOS properly ("Unknown video card") - Graphics card is recognized under Windows, though (Device-manager / Nvidia control-panel / GPU-Z and so on) - Sometimes after a crash the system recovers and a pop-up says that the nvidia graphics driver crashed and was restarted - Of course, I'm using the large 240 Watt Power supply Ok, that's about everything I remember to be relevant at the moment. I'd appreciate any kind of help :-) ... If you need further Information, just let me know, and I'll try to deliver it. Thank you, Florian
