ADMIN EDIT 12/15/15: The original referenced zip pack is now restored. Did some tests with the VBIOS of the AMD 7970m, here's what I've got so far: - Overvolting: So far no success, when I increase the 3d voltage the card simply stays at the 2d profile. Fixed that Be aware that overvolting should only be done by experienced users and can seriously harm your GPU, shorten the life of its components and lead to unsuspected effects and / or system instability. I take no responsibility for any possible damages. Overvolting has been tested by me and @widezu69 (thanks!). It works, but can lead to instability, you need to find your limit. The M15x doesn't handle it well. I noticed similar behaviour as with my overvolted 6970m, drops in clocks, instability etc. At 1.15V even immediate crash at GPU load. The M17x R3 seems to handle it a bit better, there's probably more headroom in the voltage supply circuits which are providing the voltage for the GPU. I was able to run some vantage tests at 1Ghz with a 0.05V overvolt, my previous core clock limit was at about 950Mhz... so it definitely works. Different systems will behave in different ways, only way to find it out is to test it. Don't do it if you lack overclock experience. - Undervolting: Only did some quick tests, but it seems to work. The driver crashed all the time at clocks which normally worked fine. And at more sane clocks the card worked as expected. - Update: Yes, works very well - Core / memory clocks: Works fine so far, I only tested the 3d settings, but I assume it also works for the other clock profiles. In the GPU-Z screenshot you can see the changed clocks: A package with a selection of modified VBIOS files can be found here: AMD 7970M vbios pack There's quite a bit of work behind this, so just in case you want to buy me a beer... Here's a list of what the package contains. The names are pretty self-explanatory. "uv" for undervolt, "ov" for overvolt, clocks are "core-memory" Keep in mind that you need to rename the files before flashing due to the 8 character file name limit in DOS. Modified clocks: Dell7970m-900-1250.ROM Dell7970m-925-1300.ROM Dell7970m-940-1350.ROM Dell7970m-940-1400.ROM Dell7970m-950-1350.ROM Dell7970m-950-1400.ROM Undervolted: Dell7970m-uv-0950v.ROM Dell7970m-uv-0975v.ROM Dell7970m-uv-1000v.ROM Overvolted: Dell7970m-ov-1125v.ROM Dell7970m-ov-1150v.ROM Overvolted & modified clocks: Dell7970m-900-1300-ov1075v.ROM Dell7970m-900-1300-ov1100v.ROM Dell7970m-950-1400-ov1100v.ROM All files are based on the OEM Dell 7970m VBIOS. Instructions: For flashing refer to this guide: There's a list with the checksums of all files included in the VBIOS package, I highly recommend to check the integrity of the file before flashing it. This can easily be done with ATIflash, if you don't know how please check the guide linked above. And as always, flash on your own risk, you are responsible for your system and the changes you make on it. Feel free to ask questions, feedback is welcome as well!

Help HP HDX 18t 1200-CTO w/ Nvidia GT130M and Intel Core 2 Quad Q9000 the issue is i have two identical comps like that i work on one my brothers and the other my mothers... my moms keeps temps in check and even undervolted q9000 to 1.05v from 1.25~ did the same on my brothers... the prob is these comps have one fan and one copper pipe going over the cpu and gpu causing havok when cpu or gpu heats up. Now my moms handles good it was previously mine and i kept it clean... 3 years oldish on stock paste. My brothers constant overheat probs i even repasted his on gpu and cpu.... so i need help as i have no experience on nvidia vbios flashing and editing downloaded nhibitor and nvflash and went to backup file in windows and it wont recognize eeprom as it says. help i can create a bootable usb drive have one from flashing ATi cards.... onece i have bios backup i can reflash with a little less volts hopefully running much cooler. Any links on directions on backing up bios and flashing outside of windows on nvidia hardware... i dont think its MXM is that a prob? my moms i'm even able to run a small overclock of 680-550-1700... core,mem,shader... stock is 600-500-1500 and dont get high temps even on Skyrim yes couldn't belive with graphics lowered enough this plays decent on here.

Dell has released a new vbios revision for the 580m http://support.dell.com/support/download...eid=478843 *ISO image of GTX580 A01 Vbios 70.24.2B.00.06* *The flash utility will ask for user input to override PCI Subsystem ID. This is normal. Press y whenever prompted to complete the Vbios flash.* *ISO image of production GTX560M Vbios. Burn image to CD and reboot system. Press F12 to choose CD/DVD drive. When promoted, press Y.* OLD vbios version version 70.24.2B.00.04 had 3 entries core:50.5MHz shader:101MHz(bumped shader:270MHz) memory:67.5MHz --------------- core:73.5MHz shader:147MHz(bumped shader:270MHz) memory:162MHz --------------- core:620MHz shader:1240MHz(bumped shader:1289MHz) memory:750MHz New vbios version 70.24.2B.00.06, has 4 entries: new entry is marked in bold core:50.5MHz shader:101MHz(bumped shader:270MHz) memory:67.5MHz --------------- core:73.5MHz shader:147MHz(bumped shader:270MHz) memory:162MHz --------------- core:475MHz shader:950MHz(bumped shader:950MHz) memory:750MHz --------------- core:620MHz shader:1240MHz(bumped shader:1289MHz) memory:750MHz.

Solved, see the "edit" for details. So... I just had the glorious idea to mod a very old beta vbios of an 6970m ES and try it on my card... but now there's one big problem, my system won't POST anymore. The SCROLL an d CAPS leds are blinking, which means the GPU is preventing the system from POST. ... and since it doesn't POST I can't even blind flash the card. So, my guess is, the card is still ok, but the vbios fails completely. (I don't think the card is dead...) Anyway, the only way I can think of to solve this, is putting the card in a system with 2 GPUs (e.g. M18x). Do you think such a system would boot with this card and allow it to be flashed? __________________________ EDIT: Successfully reprogrammed the serial flash memory chip which stores the VBIOS, more details about the whole procedure can be found here: Recovering a notebook GPU from a bad VBIOS flash | Tech|Inferno __________________________
