Ah, come on NiBiTor

Long story short, I want to up the Extra clocks on my GTX 260m.

At stock, the GPU in my Asus is downclocked to 500/1250/700. Using the methods described in Tev's Guide, (and with a lot of help from Soviet), I crafted a new vBIOS to give me clocks of 550/1375/825 and downclocked/undervolted everything else. Note that the NiBiTor used in the guide is 5.1, and you need to use a workaround to edit/use the vBIOS.

Everything worked just fine.

However, I want to raise the clocks up again, to 580/1450/850. So I download and use NiBiTor 5.4. Apparently this version detects my GTX 260m without a problem and no need for a workaround. So, I leave everything else the same and just change my clocks to 580/1450/850. Save as ROM, load to USB drive, etc etc.

So I flash my GPU, and everything is good. No magnificent brickage, no weird screens, nothing. Works just fine... until I check my clocks in GPU-Z. My clocks are now inexplicably 500/1250/800. I recheck, reflash... no change. Still 500/1250/800.

I then flash using my previous vBIOS that used NiBiTor 5.1, and this time the clocks stick at 550/1375/825. The 5.4 vBIOS is borked.


Am I missing some important step here?


EDIT: By the way, when I pulled the 5.4 vBIOS from my machine using GPU-Z, NiBiTor reads the extra clocks as 500/1250/800, but the other undervolts/underclocks are exactly the same.

 

try this when you flash:

Here is a link to a vBIOS that has the clocks that you want.

http://www.filefront.com/15662883/260m.rom

See if this one works. Then flash with the following commands:

type: nvflash -4 -5 -6 260m.rom


See if that helps.

 

I'm not currently at my place right now, so I can't flash it just yet.

Out of curiosity, was there a specific step that you did for that? I'd hate to hex my voltages over again (or have someone do it for me since I'm not all that savvy with hex), so maybe I could apply your method to my "older" vBIOS.

 

Just don't use 5.4 then??

 

If I could find 5.1, I'd use it. Anyone have a spare copy that could stuff into a .zip?

 

Several things.

I DLed the newest version of nvflash (5.88) and my clocks still would not stick.

I used NiBiTor 5.1 (with the full workaround), and clocks would not stick.

I used Naticus' ROM, and upon restart I was told a valid MXM structure was not found and POSTing was delayed by thirty seconds. Windows hung on boot.

Flashed to my 550/1375/850 vBIOS, and those clocks stick.

So I'm back at square one. Weird as hell.

 

Any takers?

 

I have version 4.0, do you want it?

 

Have you tried underclocking or overclocking the gpu using the Nvidia Control panel that comes with the drivers?

I only flashed the BIOS of my 9600m GT for the purpose of undervolting it to 0.89V.
Aside from that, I OC-ed the card past the 9700m GT stock clocks using the Nvidia Control panel.

 

is this what you are looking for?

I already found 5.1, Bubzers. Thanks, though.

As for overclocking, I'd rather it be permanent. Also, there's the little annoyance that it used to work perfectly before.

 

i know exactly what you mean. why can't we just leave well enough alone?

have you tried reflashing back to original and starting the procedure over?

 

I've tried that. In fact, when I flash a new vBIOS, it defaults back to the stock 500/1250/800 vBIOS.

Just this new vBIOS I make in any form of NiBiTor doesn't want to stick. I don't even know why it doesn't stick. I'm more interested in finding out the why more than the actual overclocking at this point.

 

Is the Extra voltage still at 0.95V, or did you bump it up to the NVIDIA reference 1.0V? Maybe there's something in the BIOS preventing the clocks from going too high at that voltage?

On the other hand, my card clocks to 585/1463/950 just fine through the NVIDIA Control Panel (I haven't flashed anything in my life).

 

I can overclock just fine to the clocks I want at .95 volts. And I used to be able to flash whatever I wanted to.

Suddenly I can't anymore, which is why I'm puzzled.

 

Technically, You can set any voltage You like, using NiBiTor. There is a built-in tool to do it. Just click on Tools/Voltage Table Editor. It works for me (MSI GX720 with 9600M GT)

 

And you can test out mad hexing skills for the voltages you don't get by default.

Problem is that my voltages are still wonky, along with my clocks.

 

The built-in voltage editor is limited in the lower range. Hand editing the BIOS is the most flexible approach.
