NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks


Recommended Posts

Thanks Sekence.

I was just curious because I used nvflash to backup my 80.04.29 vbios which is ~88kB, while the modified 80.04.33 vbios is almost double that at 157kB.

Although there's probably nothing to worry about, should I be concerned before I flash from the old 29 to the newer 33? I was going to use a fat32 Usb win98 boot drive just because I've never had any problems with it before.

If you have a Clevo EM system then you are fine. If you have an HM then stay away from the UEFI (bigger) versions except the once based on MSI.

I have a msi 16f3 (gt60 barebones) with a 675mx. When I try to install the mod with nvflash, I get "ERROR: No NVIDIA display adapters found". I can confirm my card is working, its the 4gb 675mx, scores 4300 stock on 3dmark 11. Any help would be appreciated, ive seen some get to 6000 on 3dmark 11 with this mod and id love if I could do the same. Thanks.

That's great. It seems just the modified vbios sent me from ~5800 to about 6200. Running 915/2150 I reach about 7200 in 3dmark11 which is a huge jump on stock volts. Temps went from about 74 to 79 however, though definitely still safe.

All of 3dmark11 benches run without any artifacting, but between tests there is sometimes some flashing lines of static that I believe are just due to changing resolution from 1080p (native) to the 720p used during testing. Should I be worried?

Also, what does GPU-Z report others' 680m Asic quality? Mine reads 66%.

67.1% here. And 79C in 3dmark11? Considering how short it runs that is a bit high. I would expect games to be significantly hotter.

Update:

Just ran 3dm11 with fans on auto at 1V 954MHz and hit 80C, and games hardly run any hotter, so 79C is ok in 3dm11.

I had this issue when I flashed a custom vbios to my 460m on an Asus.

Try -nvflash -4 -5 -6 newrom.rom

Thanks, still didn't flash though :grumpy: Mismatch in 256 byte page mode programming. I now have a hatred of that sentence

Yeah, try this, I can't think of much more. Clevo seems to have a very weird implementation of the SPI bus.
Pretty much about to give up now, pity as I upgraded to this laptop and didn't take the 680M option as I though I could flash and get stock 680M speeds out of the 675mx for les outlay. Are you sure that one of the pages in the modded VBios isn't larger than 256bytes? ( I could be entirely wrong here) I'm willing to experiment to try to sort out this problem if you are willing to help

Flashing in dos? or via nvflash in windows? if in windows open gpu-z and try again, it seems unless you activate the gpu it won't see it. That's what I've found anyway. If in dos I have no idea.

ASIC on my 675mx is 68.8%. Makes sense really as all of the mobile GK104's will be chips with faulty shader clusters(the ones on the outer edge of the silicon wafer) that didn't cut the mustard as desktop GTX680's

OK, well now it sees it. I made it see the card by going to nvidia control panel and adding nvflash to use the dedicated card. Now I have this issue:

Checking for matches between display adapter(s) and image(s)...

Adapter: GK1xx (10DE,11A7,1462,10D9) H:--:NRM B:01,PCI,D:00,F:00

WARNING: Firmware image Board ID (E11F) does not match adapter Board ID (E120).

ERROR: Board ID mismatch

Is this made just for the msi gt60? Will it not work in the unbranded 16f3?? :confusion:

EDIT:

So this is REALLY weird. My Nvidia control panel AND the specs of my computer say I have 4gb of graphics memory, yet GPU-Z says I have only 2GB. I trusted GPU-Z and tried the one for the 2GB card. I didnt get the error that I got before but a new one:

What in the heck could be going on here?? I'm even more confused why GPU- says I only have 2GB of gfx memory available while everything else says 4gb, but then its actually right! WTF??

You need to use the proper vbios version for your board... what did you try to flash, and what is your current version? Details of your card?

I tried flashing the (2GB) - 80.04.58.00.14_'OCedition'_rev00 version for the 675mx on a 16F3, unbranded gt60. Here are the details of the card:

Operating System: Windows 7 Ultimate, 64-bit

DirectX version: 11.0

GPU processor: GeForce GTX 675MX

Driver version: 314.07

Direct3D API version: 11

CUDA Cores: 960

Core clock: 666 MHz

Memory data rate: 3600 MHz

Memory interface: 256-bit

Memory bandwidth: 115.20 GB/s

Total available graphics memory: 4095 MB

Dedicated video memory: 2048 MB GDDR5

System video memory: 0 MB

Shared system memory: 2047 MB

Video BIOS version: 80.04.58.00.1E

IRQ: 0

Bus: PCI Express x16 Gen3

Device Id: 10DE 11A7 10D91462

Part Number: 2051 0005

Please upload or send me a copy of your vbios.

EDIT: Got it working! And wow this things amazing! My max temp was 65 on 3Dmark 11 and I got a score of P6264!! That's over 2000 points higher than stock! The stock speed was 667 core and 900 mem, I pushed it easily to 1050 core and 1100 mem. Pushing it like this gives it really close result to the 7970m, as its max score on 3dmark 11 is a little over P7000. It pushes way over stock 7970m though. Thanks svl7!!!

I wasnt aware there was an overvolted vbios for the 675mx. Thought they were stock voltage with unlocked clocks?

I found two off the web for Clevo 675MX as well (do not remember from where) so if anyone has Clevo with 670/675MX can try them (the 670MX bioses were posted previously).

NVIDIA GeForce GTX 675MX video card benchmark result - Intel Core i7-3630QM Processor,Micro-Star International Co., Ltd. MS-1762 score: P6590 3DMarks this is what i get with 675mx +440 core +810mem 1.37V which is stock and max stable point and according to this benchmark my cpu is bottleneck for my score as you can see that my physics score is bit low. anyway to improve it? for my gpu i can hit max +470 on core with little bit shattering or sometimes crash with stock voltage. can i increase the core speed more than this with OVed vbios? like 1.37 to 1.5... is it possible to push it till 1.5 on 180watt brick? tnx for any reply

Gokica have you used this bios? Little nervous about flashing random vbioses.

I am afraid not. I have ASUS G75VX and it has different Vbios. So do not risk. I just left the files for reviewing purposes by the people that know how to mod bioses.

Hi all, I'm new here. I'm getting a new Clevo P150EM very soon. I don't quite understand which vBIOS I should download for the best performance. There's one Clevo version on the first post and 3 Clevo versions with seemingly different voltages on the second post in the attachment section. Which is the latest release and the one I should download?

can I ask what you did to get it working? as I'm currently stuck with the 256byte mismatch error

@svl7

I don't if this will help but here is some extra info from my card. The last command shows the mismatch offset when comparing your modded 675mx 4gb Clevo Rom. If you could please have a look I'd be most thankfull.

Hey gents, I'm new here. I've got 2 Sager/Clevo 9150s with 675mx and i7 3610s to work with and so far haven't messed with the vBios. With normal overclocking I'm able to get about 5050 in 3d mark. I've taken the RAM on one of the laptops up to 825 and it was pretty stable, but the other one seems to top off at around 675 before I get artifacts.

I'm going to try the vBios from the beginning of this thread and see what taking the core clock up a bit can do for me. I'll post my results later today I hope.

Thanks for great work on these!
