Adjusting Voltage!!

[Big.Wayne]

Previously on a forum somewhere near you:

Hi, I have heard various angles to this one and I am led to believe that it is not possible to softmod a VGA cards voltage, you gotta get your soldering iron out and hook up some stuff.

with ATITOOL on x1xxx cards you can change the voltages , you dont need any Vmods

So can anyone comment please?

Some ATi chipsets let you change voltage within limits, most don't, or at least you can't get at it.

The most challenging, and often most annoying part in overclocking your new uber graphics card is the voltage adjustment. Not everyone is technically gifted enough to apply a voltage mod to increase the GPU/Memory voltage. (Never mind bringing in the risk involved in this process.) In the past, only MSI and Abit offered us the ability to adjust the voltages with software. ATi has finally made the leap and given overclockers a reason to celebrate. In their new RADEON X1800 series they have given us the ability to modify the GPU/DDR voltages without using a voltage mod. Unfortunately, this useful feature never screamed out enough to the users like it deserved to be, until now. This step is giving a lot of respect to ATi from the overclockers. From now on you can exponentially limit your risk to the card without a voltage mod.

NGOHQ: "We love that you’ve added the voltage adjust feature in the latest builds of ATiTool. Can you give us some insight about this feature?"
W1zzard: "I personally think it’s a good way to bring voltmodding to the masses. I must mention, voltmodding does pose a risk to your card even accomplished by software or hardware modding, its much safer using the voltage adjust feature provided now."

NGOHQ: "Did ATi provided you with the information you needed to add this handy feature to ATiTool?"
W1zzard: "No. Unfortunately, ATI has never been helpful in any way during any stages of ATiTool development."

NGOHQ: "Do you think it’s possible to add the same feature for NVIDIA GPUs?"
W1zzard: "Most NVIDIA GPUs support voltage changes already. So, while it’s possible the problem is finding the method to do it."

NGOHQ: "Have you tried to contact NVIDIA about it?"
W1zzard: "Again, there is no manufacturer’s support for "tool writers" from NVIDIA either."

Think it's the X1800/X1900/X1950 cards that let you change a few voltage options.

Ummn, its been well known for aages that x1k series have software voltage control. Some of the lower cars dont but the x18 and x19k do.

Ummn, maybe for you, I didn't know and I still didn't speak to someone who said it actually works?

Have you tried it yourself Concorde?

I think everyone that's overclocked their x18/19k card knows this

And yes, it does work, i've done it myself.

It works within limits. Some more extreme benchers still hardmod to go further.
