@ 2010/10/12Getting a N460GTX Cyclone in the test lab worked out well since HWBot and MSI held a competition for GTS 450 and GTX 460 GPUs, sadly N460GTX Hawk looks hotter than my Cyclone. Oh well, armed with soldering paste, a Weller and some data sheets I thought that nothing was impossible, so I compiled some mods and wrote a small guide for those of you have a cards lying around and wants the most of it.
First of all, the standard VGPU, the voltage for the GPU is pretty weak. Afterburner lets you set up to 1080mV, which gets you nowhere really. My first step was to solder a real mod with trimpot for higher VGPU. The problem now is that OVP is ~1.2V, which caused quite a headache. Then came Henry, ME4ME to the rescue and taunted me for my Frankenstein approach to modding, and through luck we managed to get VID to 1.08V by removing all resistors marked on the pictures below. Even an OCP mod (hardly necessary) was done while we were at it. With the VID mod the OVP goes up to 1.3V, which is a lot more interesting for those interested in more extreme cooling. The VID mod should be used with the VGPU mod.
