I have an 800w power supply powering my x58 p6t MB i7 920 slightly overclocked about 10 fans 3 harddrives and 3xSapphire Xtreme 5830s. I have the gpus overclocked to 950/500@stock voltage but I know they can go higher pretty easily but Im wondering if they may end up pushing my psu too hard.When they get to around 1000 after 30min to an hour there will be a display driver crash. Or does it sound like I need to increase the voltage going out to the gpus.
Also I use sapphire Trixx to do my gpu overclocking and when everything is set at stock the cards run at 800 core 1000 memory and 1125v for two of the cards but the other one runs at 1163 volts?
? Anybody have any Idea why this would be because I dont want to the card to be killing itself. I dont have anyway to reduce the voltage on it and to me it doesnt make sense. Please let me know if this has happen to you or you know what the deal is. Thank you, Russell
p.s. This is my second post here and I really love the forum it seems to have a ton of knowledge. I only learned of bitcoins about 1 month ago and decided to upgrade my 4890 to the 3x5830 and now hopefully trying to start building a new rig. Keep up the great work guys
