Hey guess I am here again after long time cause my net was f***ed up.....I have some questions for overclocking. 1. Will overclocking a graphics card only GPU not CPU wil also increase the temps of ich in my board since ich temp are already high? 2. Does changing core clock voltage will also affect other components of pc? 3. Is core clock voltage can be changed in any motherboard or only in some boards? Does mine board support this? 4. Last question is Does all graphics card models have same core voltage? I have gtx 460 and my cousion has gts 450 so these two cards work on same voltage or not. How can I measure the max safe voltage for these two cards. Any help will be appreciated.THANKS.
