    On my Clevo WA50SJQ, I just did some simple overclocking and benchmarking with 3DMark11 (1280x720 Performance)

    Stock = 4526
    OC (+130/+130) = 4853

    Stock = NVIDIA GeForce GTX 850M video card benchmark result - Intel Core i7,Notebook WA50SJQ
    OC (+130/+130) = NVIDIA GeForce GTX 850M video card benchmark result - Intel Core i7,Notebook WA50SJQ

    I tried to clock the memory higher, but anything higher than 135-140 resulted in artifacts.

    Without a modded VBIOS, I can't do anything else I don't think.

    Temperatures didn't change much. Still hovering around 68-70 degrees.

    Either way, impressed with this card. Coming from a 750M that had a 3DMark11 score of around 2400-2500, the 850M is a very nice upgrade.

    Its undoubtly a good card. I reckon you are sitting with the DDR3 version and not GDDR5 based on that score?
    You will most likely need a vbios that allow you to enable some tiny more voltage to do more than +135MHz.

    was about to bite on a w650sj but realize they all have gddr3 version of 850m. perhaps thats the reason why it cant oc much on ram.

    still very decent score though. faster than the 765m atleast in 3dmark11.

    well, if you look at game benches, the GTX850M is faster in some games (Bioshock Infinite or Metro Last Light), a little slower in Crysis 3 and just on par in quite some other games.

    roughly you get the same performance, which is not bad at all, concerning the price point NBs with this GPU are sold.

    I got 5000+ 3dmark11 graphics score with +130/+199 on a Asus N550JK. It's a great, fast card for what it is.. It's the DDR3 that's holding it back from more potential.

    Edit: DDR3 versions don't OC on the memory very well. . I got artifacts at +200.. I guess I had a pretty good 850m in my previous N550..

    Decided to just see if I could dump the BIOS using NVFlash since I couldn't do it with GPU-Z.

    Using NVFlash 5.163.. the device is recognized, but I get an EEPROM error.

    "EEPROM ID process failed"

    Yeah, using a batch file to force p state and clocks.

    batch file ?

    I had a 740 once and all i did was select pstate 0 and had room to overclock past 135, very easy and worked like a charm..so why on earth would you get a modded vbios to lower the lifespan with volt increases and risk of bricking gpu

    Because there's no other way to increase clocks? You have to increase voltage sometimes otherwise, there will be ceiling to which you will be stuck at..

    Guys, i have an Acer v3-772g with the 850M GDDR5, and the latest drivers installed, i use Msi Afterburner to overclock, and i have some problems, i have to run it as an Administrator, and this would not be a problem, right now i'm at +135 on core and +295 on memory but often it give strange results, like that i can't touch the core or says that my memory is at 65536, checking with gpu-z when i have these results says that my core clock is at default and my memory at +1000 mhz (without any problem, by the way :eek:) when this happens, sometimes is enough restart the application, other times i can't do anything, even restart the pc doesn't work. Could someone help me? And how does it work nVdiaInspector to pass the 135 mhz limit? Thank you :D

    Hello guys, is the 347.88 driver can recognize already the new 950M? I read this the driver which necessary to overclock, the newer ones will fail to do. Also what is that +135 Mhz barrier, how to pass it without bios modding?

    I just got this card the GDDR5 variant on a clearance gaming laptop a couple months ago, haven't overclocked it just yet though but I think I can get GTX 860M performance out of my card if I ever decide to overclock it.
