Rama, im advising on an issue frequent to GTX 580's of late.
1.025 is within the stock vid range (1.0000 V - 1.0625 V) and is usually auto negotiated by the gpu itself.
However of late some parts have come out which fail to negotiate a stable voltage by themselves and results in unstable Dx10/11, hence Asus and MSI (of note) have released updated bios's which defaults the min vid to 1.0250 and on overclocked parts, a max vid of 1.0830)
keeping to 1.025 which is the new nvidia advisory for overclocked parts is completely safe.
