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 :)

Hi @flodotz!

How did you manage to install the proper drivers from Nvidia under your OS despite you get an "unknown video card" message in BIOS? Is switching between Intel HD and ext GPU working for you? I am having problems with driver installation, not to mention card detection. In my case it's M6700 with GTX880m inside.

 

From what I know you should be good with the 240 Watt PSU, but if you get a chance, you might want to try out a 300 Watt one. Maybe there's someone you could lend it from?

 

Is the cooling mounted properly? Have you checked whether the heatsink fits your card properly (although it should as it was a NV --> NV swap)? Did you make sure there are thermopads mounted in every important point of the heatsink and your cooling paste is spread in the right way? Finally, are you sure the GPU you bought is fine? It does sound like a throttling problem - some time ago I had a similar situation with a desktop Radeon 9500 PRO that was too overclocked and I damaged it's memory.

Hey,

 

to be honest - I don't know!

Drivers from the Nvidia website installed without any problems under Win7 Pro N x64 in my case. However, Drivers from the Dell website claimed that no compatible hardware was found.

 

think Optimus switching was working when I had the K41000M installed, but I'm not sure anymore.

 

It turned out, that I only got all these Issues, when my m6700 was attached to a docking station (I even tried both I have - the large "advanced" one, and the tiny legacy port expander). It worked perfectly fine when the notebook was standalone ... Even overclocking by 250MHz and hours of full load gaming/benchmarking produced no crashed.

As the docking capability is quite essential to me, I was not willing to accept this issues. I tried a few more things, like a clean Win10 Edu x64 installation ... but the error was persistent.

 

So I ended up removing the K4100M from my notebook. The seller offered me to trade it for a K4000M which should be compatible with the m6700, which I did.

I have not installed the K4000M yet, though, because I am waiting for the Dell service to fix a CPU heatsink screw I assume they damaged during the i5-->i7 upgrade my m6700 got last year (but that's a different story...).

 

I've read through your thread, but unfortunately, it seems I am not much of a help in your case :-(

Have you tried turning Optimus off in the bios and booting windows? Is the 880M recognized under Windows then?

Who needs optimus anyway :P ... I'm getting ~4 hours of battery life with the current K3000M, should be enough I think :D.

 

Cya,

Flo

Hi again :)

 

 I've heard the K4100M should be compatible with M6700, as the K5100M is - they even have drivers for it on the official Dell website. Is it possible that the GPU you had is malfunctioning? When you place the K4000M inside there should be no problem - this workstation was sold with that card so my guess is BIOS will recognize it.

 

In my case the card is only recognized by Windows, yet I can't really install any drivers. Playing around with Optimus gives nothing. This weekend I'm going to try out a K5100M in it and see if it works.

Hey there,

 

Yep, that's what I've "heard", too ;-) ... maybe it is compatible in some hardware configurations, but not in others ..  (only god may know how this extremely weird incompatibility with the docking stations emerged)

Hmm I don't think I had a bad copy of the K4100M, as it worked perfectly fine when not being in a docking station.

 

I'm looking forward to your reports with the K5100M! ... Do you have a dockingstation at hand? Would be interesting to find out if it gives you the same strange results as my K4100M.

I am going to swap my GTX880m for K5100M tomorrow and post the results here. Unfortunately I only have a small docking station for this laptop, but if you want I might give it a shot.

 

How did you find Quadro cards for gaming? Is it any good?

I'm curious :)

As I've said, I also have a large Docking station (PR02X) and a small Port-extender that can be left attached to the notebook permanently (N054C), and I had the same Issues with both of them, regardless whether Win7 or Win10 (I think it never ran for more than 10 Minutes before crashing).

However! When running on battery power, it never crashed, even when attached to a docking station. Extremely weird.

 

I was quite satisfied with the performance of the K4100M. Of course it's not as fast as a GTX880M, but with a modded vbios you can push the clocks quite drastically (I think it ran at 950MHz core clock or so), improving performance substantially.

It could run Crysis 3 in 1920x1080, all Very High settings, and low AA at smooth framerates then :-) good enough for me.

Allright then - I'll give you some feedback when I manage to do the testing. Actually I'm about to fiddle with it tomorrow (I always hesitate whenever it gets to opening the M6700 - already did some damage to the touchpad connector) so I'll keep you updated.

 

If everything else fails, I'll keep the Quadro inside and OC that baby to play The Witcher 3, which is my goal for this Dell setup. The K5100M will be better then the GPU in a Sony laptop I also own (low profile 740m with 64bit memory bus).

Yep, I'm a bit nervous, too, when opening it. While it is built up relatively logically, there are many little things that could theoretically be damaged.

 

Don't worry, I think the K5100M should give equal performance as the GTX880M, at least when overclocked a bit.

Even my K4100M made 4500 Points in the Passmark 3D Rating ... which is more than the average GTX970M achieves. (there are systems with GTX970M exceeding 7000 points, however).

I guess that's up to the cooling and vBIOS settings.

 

I got the M6700 very recently and am happy to live with it, despite it's rather big size and heavy weight - it's definitely a desktop replacement for me. For the last two years I've been using a Vaio laptop for pesonal use and it's nowhere near the build quality and performance as the Precision series. Give me the better GPU though! :)

 

edit

Hi again @flodotz!

I have just installed the K5100M into my M6700 and guess what - I've got the same problems that I faced with the 880m. Os refuses to install drivers, even though I get them modified. What CPU do you have? I've heard there are problems with Intel's XM CPUs when you try different GPUs.

 

edit 2

The K5100M works now - I managed to mod the drivers even more and somehow got it done (wondering now ehether I should give the GTX880m another go). I have a Dell PR04X docking station which is only a small legacy extender (http://www.dell.com/en-us/shop/accessories/apd/430-3115?c=us&l=en&cs=19&sku=430-3115). When I plugged it in, it was installed as a generic USB HUB. Just ran Furmark and Bioshock Infinite on ultra settings and I got no problems at all. The temperature while running Furmark reached no more then 70 Celsius.

      Hi all,
       
      It has been a while since I did anything to my laptop (Clevo P670RG-G) and since I recently got a VR Headset I wish I could overclock my GPU a little. So far the NVidia software (on windows) doesn't allow me to overclock it (the linux sort of allows, which some custom Xorg options) so I decided to give a try modding the vbios.
       
      I read all sorts of issues / guides about it, and it seens that the hardware topology (where the vbios is stored and how things are connected) changes from machine to machine.
       
      What I know about my laptop is that it has two VBios, one for Hybrid Mode and one for Discrete Mode. I'm currently running the discrete mode.
       
      I dumped my VBios using GPU-z and opened up in Maxwell II Bios Tweaker. Everything seens fine so far.
       
      So I have few questions about it:
       
      - There is a way to just unlock the VBios to show the overclocking options in NVidia software? (That way I dont need to reflash to change clocks)
      - I can just flash this GPU-z dump to my VBios?
      - If I brick my GPU, that GPU-z dumped image is the raw SPI image, so if I managed to physically access the VBios, I can just reflash over it?
      - I saw some people saying that I might need as well to flash the main laptop bios as well, is that really needed?
       
      Thanks!

      In this thread you can post your requests for Lenovo ThinkPad T440p / T440s / T540p.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating bios backup and to flash bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      Hey everyone!  After lots of searching it looks like this is the go-to place for laptop mods online, so I figured this would be the best place to ask something like this.
       
      I picked up a Dell E6530 for basically scrap value, and I love the thing.  Runs Xubuntu great, battery is halfway decent, and I can play 99% of the games I own on it.  My friend on the other hand picked up an E6440 with its silver-ish finish along the back.  As much as I love my 6530 I've gotta say, that thing looks great.
       
      To get to the point now, I was wondering if it's possible for me to polish the top of the lid on my 6530 to have a more silver finish like that (or maybe even a mirror finish if I sand it down with a fine enough grit).  Really what I want to know is if the dark grey part of the lid is actually metal.  I can't seem to get a definitive answer online, and I tried the magnet test on it and it wasn't magnetic at all.  This doesn't necessarily mean it's not metal though, as aluminum isn't magnetic but is obviously a sandable/polishable metal.  One source said the laptop has anodized aluminum parts on it, but they didn't specify whether it was something internal or external.
       
      Can anyone here provide me some insight?  If the grey part is definitely a metal and not a plastic, I think I'm gonna give it a try.  As stated before I got this thing for scrap value, so if in the end it doesn't work out I'm not gonna cry over it or anything.  Still though, I'd rather not run into this blind.  If this is indeed possible though and I can accomplish what I want with a decent looking result, I'll post up some pictures with the method I used for others to do as well.
       
      Thanks in advance!

      Hello,
       
      I have a Dell Inspiron 5555 with BIOS A12 and I am missing some options in the advance menu. The BIOS seems to be shared between the 5455 and the 5755, if it helps. Can anyone help me figure a way to have all the options in the BIOS available?
      I have attached the results archive from the backup tool, if it helps

      Thanks in advance!
