GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/19 10:01 Hey Mavke

I stumbled upon this site when i found a post over on another site about a guy who had his GTX 580m voltage increased by you and the results where pretty good!

So I was wondering, ive attached my bios file to my GTX 560M, it has come out of a Clevo laptop, model number P151HM1 (but has the P150HM motherboard as the P151HM1 is only cosmeticly different to the P150HM) and i was wondering if its possible if you could check out the BIOS on it and see if it can handle any more volts ?

At the moment it runs 1.000 volts at 3D clocks.

Any comments would be appriciated

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/19 22:48 Thanks for asking and sharing your original BIOS of that GeForce GTX 560M device and having checked it is a bit different from the high-end version, which means that I can provide a tweak just like that, but will need some extra checks to be done on what is different. That is why it is so important to get the original BIOS image, which will allow is to verify and unraffle the settings. I will keep you posted, though it is a quite busy few days I am going through, so I hope you have some patience.

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/21 04:38 Hi, I would like to set core at about 900 and memory at about 667 same as memory controller on i7 chip
I think that makes games run smoother. Then I would like to set memory to 800 if I get some 1600mhz ram . Basically card memory = ram everything running the same speed. Without Having to use msi afterburner at startup.I used to change bios with rbe when i had a ati graphics card.

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/21 09:17 As said to the previous person, you will need to have some patience as I don't have that much time the next few days and the GeForce GTX 560M is a bit more different than the others though once I get some time these tweaks will be feasible. However, I don't see how matching the memory speed of the graphics card with the memory speed of the system will be better? There is no link between those whatsoever.

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/21 15:26 Thanks for your respond Mavke. I noticed that the cards memory was clocked at 625, and noticed that the system memory is right around there at 667 and wondered why they would pair this card with this system if there wasn’t a reason. And there both 128 bit memory controller 64x2. And when I run the memory at the same speed my games seem to be smoother. It may just be me. I read a long time ago if you have things running at near speeds you won’t have bottlenecks there for graphics will appear smoother. One thing won’t be waiting for the other. Vram / shared memory. Thanks again.

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/21 19:59 Euh, well I am really not convinced and you simply overclocked the memory of your graphics card which means games will run smoother as the memory can act faster to supply data. But that matching with the system memory speed doesn't have anything to do with how smooth games will run cause if else I would need to clock down my graphics card to match my system memory speed. Your games just run smoother cause you gave a little extra memory bandwidth.

Re:GTX 560m BIOS attached - Can you increase the voltage please? - 2011/07/22 07:09 Checked the GTX560M_CLEVO.bin
Its voltage table has 8 values.
0.82v/0.85v/0.88v/0.90v/0.93v/0.95v/0.98v/1.00v

1.0v is the highest. If there is a way to raise the voltage, it would be different from raising 580m's voltage.
