Ummh I don't think so cause I already had this kind of problem with my old card (880m) but only with all nvidia driver after 327.23 (very old driver) now I just tested another driver just for check and as I can seen is that my gpu clock always throttle but not at 475 but 800mhz, of course I don't know where the real problem is but because I already tested several psu and because I current PSU is an 330W, I don't think that problem come from the VRM converter or this is the first time I heard that from this model of laptop, and in this case, how explain than differents drivers change the frequency of the GPU clock if I don't touch anything else ? Also when I try to change the voltage or memory frequency with the vbios mod, it's doesn't change anything, it is normal ? Maybe you could check my stock bios and see i you can change something ?

Sadly I always make this, it is possible that problem come from the nvdia driver ? What do you mean by hardware problem ? the card is broken ? I always problems with my cards, 880m with huge throttling before (never been fixed) and now this one, f*** nvidia.

It's weird it's indicated gpu clock max 541Mhz but when I don't use any 3D application, the clock bring me up to 1126Mhz

Hi Klem, can you please unlock my current BIOS ? I have a throttle on my gpu usage (about 475mhz max when used but 1126mhz in idle with the vbios Nvidia GTX 980m - 'OC edition' rev0 ). With the original bios, I have more limited by memory clock this time, 799mhz max and 1037mhz for the gpu clock Thk a lot ! dell_980m_original.rom

hi there, I started to read this thread there are few weeks but there is too big now, just for my information, it is possible to install correctly this 980m on windows 7 ? I seen problem with UEFI, what is the problem ? Or it is necessary to use windows 8 for work properly ? (windows 8 is a bullshit)

Hello please comment this thread on nvidia forum if you want help for resolved this problem of driver with hard throttle and flag in the gpu card https://forums.geforce.com/default/topic/754922/geforce-mobile-gpus/nvidia-crippling-the-gtx-880ms-with-there-new-drivers-look-for-a-nvidia-response-/3/ Currently, I'm always forced to use old driver version, it's not acceptable when you know the price of this card...

Hello, I found this post where mathieulh explain the problem, it come from all the new driver from nvidia who limit the overclocking : Just got my 880M twins! - Page 42

@johnksss hello, I had sent you a pm, have you received ? I explain my problem. I have no crash with the stock vbios, only with the modded bios from the svl7 thread. Not bosd, just a screen freeze after few moment, I see that the driver try to reload again and again in my taskbar but crash immediately. About the stock vbios, I have a hard throttle as you in your test, the same problem but I don't found solution for resolved this.

thk for the link but this modded vbios doesn't works for me, when I install it, my nvidia driver crash again and again and after several times, my windows freeze and I must forced to reboot by pressing the on/off button. @godfafa, and for you ?

Hello, first thank you for this modded vbios I have a 880m and my current windows is windows 7 64 bits. My laptop is Alienware mx17 R4, original graphic card was 660m. This modded driver didn't works for me, when I use the latest nvidia driver 337.88, when I open windows, the driver crash several times and after 3 or 4 times, the screen freeze, I must forced to turn off the laptop by pressing the on/off button. Any idea of the problem ? I have no trouble with the stock vbios,always just the hard throttle like in the johnksss thread : My Nvidia GTX 880M Test Run Review

yes this is the software I use, see the previous post in this thread

yes I always uninstall correctly the driver before each test

But when I flash my vbios with the vbios from godfafa, the card should be reset, don't you ?

okay pm sent, hope he can help me

I already read and quoted this thread about 880m without find the solution. I think Johnksss don't know how resolve this problem and because he has just tested the card for a few days. edit: I'll send him a pm, hope he can help me...

the problem is the same for me because I'm limited by the 327.23 driver and I don't know why, it's frustrating...

yes I think to reinstall but it take me long time

I tested the same thing and always the same problem. I don't know where to search now

Okay I took the risk to flash with the vbios of godfafa, flash is good but it's always the same throttle, I really don't understand how you can have no throttle with the lastest driver version So this is not a problem with the vbios, I guess another software problem, what is the version of windows do you use ? Do you install the 3dvision controller when you install the driver ? My current bios is A12 version, have you try with this version ? I'll try with the A11 version.

@Klem with stock vbios, always with 337.88 driver : Generic VGA video card benchmark result - Intel Core i7-3840QM,Alienware M17xR4 when I run a benchmark, voltage down at 0.8xx volt in same time with the gpu core clock. When it's done, you can see on the picture, throttle is not present.

Ok bios flashed and tested with 337.88 driver Generic VGA video card benchmark result - Intel Core i7-3840QM,Alienware M17xR4 As you can see, it's always very low, in techpowerup when I run 3dmark, the GPU up at 993 mhz and when the video is run, the gpu down at 231mhz max, memory remains at 1002 mhz

Maybe @Klem can look the two vbios for check the difference inside ?

@Klem http://yntdny3kfr.1fichier.com/ - - - Updated - - - Really not possible to make backup or reset after a bad flash ? http://www.techinferno.com/2011/07/09/recovering-a-notebook-gpu-from-a-bad-flash/ SVL7 is everywhere. All is exactly the same so I guess, it can be good... but I don't know how doing this

no, my version is 80.04.E3.00.03 (P2053-0002) Maybe your version is good for the new driver ?

no, all is good now, full charge is 69° max It's just because it was a problem with a black plastic on the copper for the 660m, now I removed, the contact between gpu and the heatsink is much better, you can check the rest of the thread for have all the explanation
