Did a test using the latest two Clevo vBIOS.

1050V and 1025V

However, the 1050V version gave me some issues and when flashing, it would give the "unidentified device" issue and not give me proper runs.

The 1025V vBIOS allowed me to run at my GPU's physical max (993MHz, no higher and is hardcapped there even when set to 1000) and did several tests.

Core/MEM (MHz) : Performance Score 3DMark11

993/2350: P8004

993/2360: P8046

993/2380: P8050

993/2400: P8038

Seems 993/2380 is the best in terms of points and will be finding one setting stable for gaming without too high of temps (though my max temp was low at 59C; don't ask how).

Guess I'll do my end of bargain and give the man another round. @svl7

EDIT: Should be from m******tin@gmail.com for $10 USD

I got this issue with MSI_FD vbios, related to nvidia driver. (got this issue on driver > to 306.23)

The gpu stay at 993Mhz on the Overclocking range of 993Mhz-1005Mhz, but if you OC @1006Mhz it must keep this frequencies.

Yeah, that's driver related. I can only adjust in single MHz steps with 306.23 or lower. Else it's 13MHz.

My GPU behaves so weird lately after I flashed new BIOS for my whitebook ms1762 because the core and memory clocks are fixed at 324 Mhz. I was so dumb that I didn't make a backup BIOS :(

Everytime I run a program that uses my GPU my system always ends up with BSOD. Nvdkllm.sys was blamed to be cause in the BSOD.

I've tried everything from doing clean install driver to flashing old vbios but without any success. I am currently using svl7 latest vbios for MSI.

Could flashing BIOS get me this GPU problem ? Or there is something wrong with my driver and GPU ?

I've been searching in google to sort this problem out but I never read flashing BIOS did this to GPU before.

Well one could have done better, but I'm not going to start a fight :P

The 1025 Clevo vbios works great so far, stable and doesn't run much hotter.

Well, since my iphone 4 died and I am just a poor student I needed a new phone :P, will pick up an extreme processor later this year probably an 2920xm/2960xm for the upcomming m18x r1 I am buying :D(I can buy one extremely cheap :D, then will sell my R4(with equiping an gtx580m, and use that money to fund the 600 euro costing m18, and with the remaining money buy anohter gtx680m, and buy later this year an r2 motherboard when they get cheaper :D))

hej

I am sorry I should have said I am using an clevo gtx680m, if you clock down to like 1023 its stable in game(skyrim,bf3,witcher played em all 3 houres straight with no problem).

update, temperature around 68-72 degrees, sometimes even lower :D

it's possible to have 80.04.67.00.01 with OV too? because it's the only clevo vBios that support UEFI + secureboot under Win8

also, is actually nibitor open & save trick working to fix vBios checksum? :) i cannot test since i have no backup notebook to flash

I only modified the legacy part. If you want to use a modified vbios, you need to have secureboot and fastboot disabled. I'll put up the new one as well when I get around to do so.

Regarding the checksum, no idea whether it would do it properly on the current vbios, but anyway, you can't make a broken vbios working by just adjusting the checksum, so forget that.

@svl7 I have just read from page 1 all the way to this very last page, I can tell you what and that is that my head hurts! So much information going on!

Yourself, John, fox etc are gods! I'm planning on flashing to the dell 680m vbios (own an M17xR4 now) in your very first post to see how that goes. I'm going to donate to you bosses because this place is truly awesome. Keep up this damn good work!

might I just ask, if one was to flash to a dell 680m vbios, would you recommend the bios from your very first post, OR one of the experimental OV ones from your second post? I would be chasing P8000. I do understand that every cards different so I may not be able to achieve this however would love to give it a red hot go! If unsure I may just flash them all!

@grechie

I have tried the dell vbios at storage voltage and the one with v1.05. With storage voltage, I can OC until 1006/2250, 3d11 GPU score P8100, with v1.05 version. I can OC until 1045/2250 and GPU score P8400. As I am using 17R3 CPU i7 2760QM is not so good so the I got less CPU score and Combined Score. The general score is between P7600 - P7800 can't pass P8000. I will do more test with v1.05 to see the limits of my card.

Anyway, there is no throttling at all. All versions work stably.

Second post is not just experimental, it's also just some more versions with additional tweaks, e.g. voltage. If you want to go for P8000 GPU score in 2dM11 then you'll need at least 1.025-1.05V.

Well, now running the overvolted 680m vbios on my SLI 680m,s in the new M18x.. All went smooth and no problems at all. We right in summer atm, so just need some cooler nights and will have some fun and see how we go.. ;)

@svl7 you are a legend!

@svl7 flashed to 1050v bios from the second post, and successfully achieved P8030 3D marks! (only upped core clock for starters) Thanks man I appreciate it! Temperatures are only around 68-70c in BF3 on ultra. Curious...is there more Vcore to be had? or is 1050v the limit? :-) Cheers

1.05v is already a big overvolt tbh, but if we'd go up to 1.075v or 1.1v u greatly increase the risk on destorying your card :D.

Plus the amount of heat will be stupid, no way you ccan play bf3 long on 1.1v.

@svl7 Since you are busy to tweak the GTX 680M VBIOS I decide to modify my GTX 670MX VBIOS by myself :) Read the thread from the first floor to the last one and finally I succeed! Very thanks for your contribution to the 680M VBIOS! See what I've done :) All based on my ALIENWARE M15x!

Stock Frequency: 600MHz/2800MHz and this one got 1006MHz/4010MHz!

      Hello, I've got a Dell Precision M4700 with a 3940xm. I've read that in this particular CPU and laptop model, the bios is locked because the stock settings are considered an overclock. As-is, the core temps on the CPU do reach up to 90-100. They seem to spike up and down a bit when benchmarked with Intel's Extreme Tuning Utility, but they certainly do reach over 90C. Is there no way to unlock this bios (version a18, though a19 is released - I haven't updated yet, should I?) and even if there were, would my only option be a heatsink mod on top of that?
       
       
      edit: I've mistakenly posted this under Desktop & General Hardware, perhaps a mod could move or delete the thread? Apologies!

      Hello, I've got a Quadro M2200 (GPU: GM206GL-A Revision A1, and MxM 3.0a Maxwell card) with the following bios: 84.06.76.00.1C
       
      I've read that this card is very similar to the GTX 965m, but that it has been underclocked considerably. It seems to be a good candidate for unlocking since I hardly see the temperature exceed 70C as-is. I'm requesting help with this - I'm not sure if it's possible to simply flash the vbios from a Dell GTX 965m (MxM 3.0a) or if some type of edit of the card's current vbios would do the trick. I'm hoping someone could help me out with the specifics of doing such an edit if that's the case. 
       
      Thanks!

      Hello Everyone,
      I am an owner of MSI GT70-20C and my GTX770m gpu i now dead.
      I have a question and i hope someone will help.
       
      I have ordered GTX 970m 6GB DDR5 and i cannot find the exact vBios for that graphic card.
      My current bios version is: E1763IMS.51B
       
      Thanks in advance,

      I own an Asus Fx504-gm laptop with an 8th gen i7 and nvidia gtx 1060. I ve been having issues with random hard freezes and I later found out that absolutely anyone with this exact model has the same issue and not even Asus service can fix it as they just replace every component and the problem persists so my guess is that this is software related.
      I ve been noticing that I Always hit power limit(I monitorised it with afterburner) and so I have power limit throttling. The thing is, for this laptop the power limit is locked and I cannot modify it.
      My last resort is to try a modified bios that can unlock the power limit slider. My question is: Is this possible? Are there any modified bioses that can unlock the power limit or the only way is to unlock it via the motherboard? If so, where can I get a reliable modified bios for my laptop and how can I check compatibility? Thx.

      Hello all! I have been researching upgrade paths for my M17x R4 and I have decided on the GTX 1060. Now, I was given this laptop with a dead GPU, and I had an M17x R3 already. So I moved the GTX 560m into the R4 which has worked fine. Now as I understand it a few things are needed for this upgrade including the 120hz panel and the ability to disable the legacy ROM for a pure UEFI boot. I have the 120hz screen, but the 560m uses the GF116 architecture which does not have a vBIOS which supports GOP. So I am thinking the only solution is to buy a cheaper "in-between" card which supports both boot modes, which will allow me to disable the legacy option in setup. Does anyone have any suggestions as to what cheap card to buy as a transitional part? I have been considering a 765m but I am also wondering if there are any other good choices.
