That's a good question, because your vBIOS file version doesn't match any of the 770M files on page 1 of this thread. I don't know which one is going to be compatible, either someone else can speak up if they know the answer, or I would google to see what other p150sm users have done re unlocked vBIOS flashing.

Yes, definitely try j95 instructions on the clean driver install first before considering re-padding your card. I don't fully understand your message (that's fine, English is not your 1st language), but the temperature you see for your GPU is only the temperature of the GPU core - this is the chip that you put the paste on. All the other components on the MXM board do not have temperature measurments, so it's 'impossible' to know the temperatures of your VRAM and other chips on the board. So, it doesn't matter if your GPU core is at 65 degC, if it's not padded up properly then that doesn't mean that the chips on the board aren't dangerously high in temperature - which is why I asked you if you were confident with your padding & that all the chips were covered. But, you say you're happy with the way you've padded it up, so it's probably not a problem, and hopefully a clean driver install will fix your issues.

Awesome! I remember tacumadesigns was having problems in the notebookforums, but I couldn't help him on it. It will be good if he can use grandanoke's vBIOS file to solve his problems! Grandanoke could be a saviour! ;-) @grandanoke, Hopefully that clean driver reinstall will solve your display driver problems. If that doesn't work, it almost sounds like the same symptoms of a card that's overclocked too far. Now, I know you've not overclocked your card, but maybe one of the chips on the card is not padded up properly, and is overheating and becoming unstable. (Like maybe one of the VRAM chips). How did the padding up go, were you confident you got all the chips covered? (I found that the hardest part of the process when I did mine) (I know your GPU core is not getting too hot, because you've checked that already, but there are no temperature readings unfortunately for the other components on the board).

That's a good idea j95, so that other users can just use grandanoke's VBIOS to make sure their 770M is compatible with the R3 - and plus if svl7 modifies it then it will be a fully overclockable & overvoltable option as well! It's been a bit of a mystery as to why some 770M's work and other's don't so it would be great to have nailed it down to a specific VBIOS file that is compatible with the R3.

GPUz: temperatures, frequencies, throttling. 3DMark11 to compare GPU scores.

@J95, ah, of course, the intel iGPU, I missed that when he referred to 'cpu graphics card', didn't know what he was talking about, especially as that's the first thing to understand when you install a non-standard GPU - it didn't even cross my mind!

Apologies for misunderstanding your explanations of where you were in the process, unfortunantely I can't offer any more diagnosis for your issues, I suggest you look in the thread I linked you, and read the stuff in this thread too - so that you can re-enable the audio sucessfully - after you've sorted out your resetting BIOS with a USB issue of course.

So, just so I understand your situation, you've installed your 770M, and now it won't get past the POST screen, so it's not getting to the step where Windows starts loading? Maybe it's a problem with the video card, or the video card is not compatible with your system. (There's guides all over the place on BIOS versions & settings required in order to install non-standard GPU's in the R3, so I assumed you've followed those). You could try putting your old GPU back in to see if it gets past the POST screen. If it does, then your computer is not liking your GPU for whatever reason. I've read that some users have problems getting the 770M to work in the the R3, whereas the 780M seems more reliably compatible. Here's a thread that might help (other users with 770M problems in the R3): http://forum.notebookreview.com/alienware-17-m17x/732251-upgrading-nvidia-gtx-770m-alienware-m17x-r3-6.html

@nickbl1991 I'd try using Klem's VBIOS to see if that works fine (if you've not done so already), because like you said the VBIOS version numbers are different for the VBIOS you were trying to use before, which I think was the cause of your problems. (And you shouldn't need to use a modified inf for the driver install either if you were using your GPU before in your system with no issues, or if it's a GPU model that was offered as a configurable original option for your system when you bought it).

Did you listen to my post, were you trying to flash the 4GB version? It sounds like you need to flash the 2GB version! Like I mentioned, you also need to check that the VBIOS version number that you're flashing is the same version as your original, did you do that?

I think you have a 2GB model. "Total Available Graphics Memory" in System Information of the NVidia Control Panel is referring to both the "Dedicated Video Memory" + "Shared System Memory". "Shared System Memory" is system RAM that is usable by your video card when it needs it (hardly ever probably), and "Dedicated Video Memory" is the amount of GDDR5 VRAM you have on your GPU. You could use GPUz to double check you have a 2GB version of the 680M, but I'm pretty sure from what you've said that you've got a 2GB version. One way of checking to make sure that you're flashing the correct VBIOS file is to check that the VBIOS version numbers match. You can find the VBIOS version of your card listed on the first tab of GPUz, this is the one to compare against any VBIOS files that you flash.

Post #2 of this thread says it all pretty much, this is what it says: Nvidia GTX 780m: 'OC edition' -> unlocked overclocking limits, voltage adjustable, power target adjustable, optimized performance at higher clocks Can be used for all current 780m (Clevo, MSI and Dell). I highlighted the important stuff in bold. Use NVidia Inspector to make all the adjustments that are outlined above in bold. Make sure you run NVidia Inspector with "Administrator Rights" (right click on the desktop icon and select "Run As Administrator"). - - - Updated - - - I think the first thing to check is to make sure your GPU is not getting too hot and throttling: GPUz. Flashing a modified VBIOS is really mostly to allow you to overclock beyond the +135Mhz limit that is imposed by the stock VBIOS. If you're gonna flash a VBIOS for your alienware 770M then I think you should use the one in this post: http://forum.techinferno.com/general-notebook-discussions/4635-bios-vbios-modification-request-thread-svl7-9.html#post74364 (Post #81 in that thread) For some reason svl7 has not included that VBIOS on the first page of this thread. Before you flash it, check that your card has the same VBIOS version number as the file, you can find it listed on the first tab of GPUz. You can make all the same adjustments (in the same way) to your 770M as I described to the guy above with his 780M.

I think you've just reached your maximum stable OC, (unless you have the same problem at stock clocks - which I don't think you do). Maybe it's your memory frequency, or the core frequency, that is causing the artifacts & crashing. Therefore, just OC the core or memory on it's own to work out the maximum OC for both the core & the memory. Best policy is to leave memory at stock frequencies & overclock the core to work out the max stable core overclock. Then leave the core at your max stable overclock & raise up the memory to work out it's max stable frequency. Once you've done that - then you've optimised your overclock. If you want more, and your temperatures are good, then consider raising the voltage.

That's good still!

Ah, well your ASIC Quality is similar to mine, so from that point of view you might expect it to overclock similarly, but it hasn't always been a reliable indicator from what I've seen in the past, and also not with yours it seems. Well, you might just have to accept that your chip doesn't overclock very well. A modified VBIOS with an overvolt isn't going to help that much. For mine, going from 0.925V at 928Mhz to 1.05V at 1124Mhz, that's the difference that 125mv makes, which is 1.568Mhz per 1mv, so if you're at 750Mhz at 0.925V then I don't think you're gonna get much more than another 150Mhz or so by running at 1.05V (your GPU wouldn't respond quite as much with increased voltage), but you can try it if you find someone who can mod your VBIOS.

Is that why you had to send your laptop back to the manufacturer - you bricked your card after using SVET's VBIOS Tuner on svl7s VBIOS!? I've heard users bricking their cards trying to use that combination of program & VBIOS file. I wouldn't take that approach if I was you. If you want an overvoltable VBIOS for your 675MX, then I would request svl7 to make you one at this thread: http://forum.techinferno.com/general-notebook-discussions/4635-bios-vbios-modification-request-thread-svl7.html Also, sometimes other users on this forum can create VBIOS files with fixed overvolts, so maybe one of those guys will see your post and help you out with that one. - - - Updated - - - What's your ASIC Quality? (see my post a few posts back) Are your temperatures OK of your GPU?

Yep, no problem. Did you see my edit in my last message - I don't think there's a VBIOS file listed in this thread that allows for overvolting of the 675MX. There might be one lurking somewhere in this thread, but it's not on the first page as far as I can see - have you found one yet? (So how did you manage to overvolt your last one!?)

I don't think it's possible to overvolt any stock VBIOS, and it's also not possible to overclock a stock VBIOS anymore than +135Mhz - you know that though right, otherwise I can't think why you would even be posting in this thread!? [confused!] Yes, I recommend the svl7 VBIOS for overvolting, but make sure your temperatures are good before you even consider it. You want your GPU under 90degC at all times, under 80 degC is good, and under 70degC is excellent. As the temperatures rises, then the effect of overvolting on speed of silicon degredation is accelerated - shortening the life of your GPU, that's why low temperatures are important if you're using a lot of voltage. EDIT: Upon a closer look at the ROM files in this thread, I don't think there's a VBIOS listed here that allows overvolting on a 675MX, it looks like they're just allowing you to unlock the +135Mhz overclocking limit on the core. So, I don't think you'll be able to overvolt with the ROM files in this thread.

Assuming that your temperatures are all OK, then it could be that your replacement GPU does not overclock well (all individual chips have different overclocking capabilities), having said that 750Mhz on the core is very low for a max stable overclock for a 675MX. EDIT: One supposed indicator for how good your chip can overclock is the 'ASIC Qaulity'. What is your ASIC Quality? You can find out by right clicking on the very top of the window of GPUz and then selecting 'Read ASIC Quality'. My ASIC Quality is 76.6% & overclocks very well - that might be a reference for you. Although I have seen that overclocking sucess doesn't always correlate with ASIC quality.

Well, well done for seeing the error report referring to the NVidia drivers. Display driver crashing can happen if your GPUs are unstable. It could be that you're trying to run your GPUs at a too high frequency for the voltage that you have set. You could try lowering your overclock until they become stable. I doubt it's a problem with the drivers, because drivers crash when the GPUs are unstable if they're overclocked too far. If you're running your GPUs at stock frequency & voltage, and you're still getting the crashing, then you could try underclocking the GPUs to see if they become stable - which would point to the GPUs being sub standard, at which point you could get an RMA claim under warranty.

I'm not sure about the sound issue, I think I've read that some 770M users might have had problems with the sound, but I guess they can just follow the correct installation method (same as 780M) which results in there being no sound issue.

There's a link in the first post of this thread that describes how to use DOS nvflash, and within that link it's described how to flash sli systems, here's the link to the thread I'm talking about: http://forum.techinferno.com/nvidia-video-cards/2166-%5Bguide%5D-nvidia-vbios-flashing.html#post28018 Hopefully that will help. (If you've got Windows 8, then I think the process may be different, but I'm not sure about that, or what the process is).

Those scores look pretty good to me, when I run my GPU at the same overclock as yours I get GPU score of 6467, but that 3% difference may likely be due to different drivers (I'm using the latest 334.67 drivers). I doubt your card is throttling though, because the score would be a lot lower than just 3%, so it looks like everything is working well for your system. Cool, good stuff, enjoy! - - - Updated - - - "Processors 0 through 7". Sounds like it's something up with your CPU. Maybe the CPU is overheating when you're playing, throttling, then shutting down. You could monitor your temperatures while gaming to see what's going on.

After a real quick skim of that thread it looks like widezu was trying to emulate Boost on his 680M. I don't think there's much value in doing that, I think it just makes sense for you to flash a VBIOS that is compatible with your card & system at a voltage that allows you hit the overclock frequencies that you desire, hopefully without it getting too hot. Increasing the voltage increases the temperatures, but allows you to hit higher overclocks. I'd just pick one which has a lower voltage & see how you go, then you can always flash a VBIOS with a greater voltage if you need more Mhz (as long as temperatures allow - I think you should keep it under 90degC, under 80degC even better).

They're some good overclocks you achieved there, you're getting about 50Mhz more than me at any given voltage, (my stock voltage is 0.925V, which is less than your 1.012V stock voltage). Although, I have noticed that I had to bump down my frequencies by one notch (13Mhz) to gain long term gaming stability after my initial testing, so you may find that if you have any strange crashes occurring during games every week or so that you might need to bump it down just one notch (13Mhz) on the core to get absolute stability. (P.S. your 1120Mhz overclock is probably 1110 Mhz if you check the sensors in GPUz) Pity that your temperatures are quite high & noisy, because otherwise with 1.05V you would have gotten close to 1200Mhz - a 100% overclock has a certain ring to it!! :-) (You could probably do a benchmark run at 1.05V without damaging it, but I won't push you to do it, in fact you should do whatever you're comfortable with, you've certainly got a good overclock already anyway). I wouldn't run it any hotter than 90 degC. Did you do a 3DMark11 benchmark run at your max overclock - I'd be interested in seeing the GPU score?
