    Hi my gtx 675m is throttling at 63 c i tried modded bios both from http://forum.notebookreview.com/alienware-m17x/656685-guide-flash-your-gtx-580m-gtx-675m-r3.html

    0.87v vbios: 675m.rom

    0.92v overvolted vbios: 675m92v.rom

    still using 0.87 v bios its the same throttling at 63 c my core clock comes from 725 (overclocked in msi afterburner) to 450 sudden drop in fps !!!

    using 0.92 v bios its throttling at 63 c but my core clock only comes down from 725 to 620 !! not significant drop in fps but its there !!

    I have updated my bios to A12 still the same plz any way to fix this throttling ?? also i am unable to overclock it in nvidia inspector the clock meter is greyed out !!

    Hi, this one fixed it for me. It matches P0 and P1 so the power throttle has no effect. I do not recommend the 0.92v one - it has burned cards. Also I have no idea of the source of this file so as usual - AT YOUR OWN RISK!

    You can use nvidiaInspector to up P1 to the same overclock as P0 and the voltage will not drop like it does in the original vbios.

    P0=full speed. P1=first throttle and low usage clock.

    HTH ;)

    Edit: Best OC I can get with stock voltage is around 715. After that I get flashing dots, kinda like snow. I know it's just the luck of the draw as on my 580 I could get 740 without any problems.

    Glad to hear it. Watch your temps with that 0.92v, I was too worried about destroying the card to try it but if it works for you that's great.

    Err everyone??

    My card has finally screwed up. Gotta call dell to replace. Started with BSOD's and now after 5 mins gaming (in any game and with any driver) screen goes blank and fans ramp up :(

    Like I need this, in hospital right now after emergency surgery - never rains....
