Hi all- new to the forum, so please excuse the newbie question.
I am having some inexplicable crashing on both Furmark and in-game (War Thunder and Skyrim specifically) at various overclock settings.
I am following a guide on overclocking a Gigabyte (reference) GTX680 2GB card found here: http://www.hardocp.com/article/2012...rce_gtx_680_overclocking_review/#.UtaOA55dWHg
I have an Intel i5 2500k overclocked to 4.5GHz on a P8P67P MoBo with 8GB of DDR3 PC1333 RAM and two Gigabyte GTX680 2GB GPUs. I am fueling this with a seven year old Corsair TX750 750 Watt PSU.
Whenever I attempt to overclock at anything over 50Mhz on either core or memory, I get crashes from any 3D program I run. That is, I can run them for anywhere from a few seconds to 10 or 20 minutes, but it inevitably either freezes up completely (requiring me to restart the computer completely) or crashes me to the desktop. This involves both adjusting the voltage using Precision X up to its maximum when attempting an overclock in the +150-200Mhz range on the core (I was getting inconsistent stability using Furmark that allowed me to move it up to as high as about 191MHz) as well as when I don't adjust the voltage at all, and only bump up the core to a very modest +50MHz core.
I have a very well ventilated case, and GPU temps on the 1st card (hottest) never go north of 73 (under extreme load).
In a (maybe) related matter, I find that when I leave my computer on overnight (I have it set to go into sleep mode after about 1:30 of inactivity), and try to restart it in the morning, it fails to 'system resume'; I need to restart the computer to get it back.
I don't really know what's causing the crashes, especially when I haven't touched the voltage.
Hence, I'm putting it out there whether it might be the PSU? It is by far the oldest part of my computer (bought in 2006/7), and while it's never really given me problems, I am thinking it might be having some trouble with power regulation (that's an official newbie term), but I'm unsure.
I kind of feel like the doctors not knowing what some kind of ailment is and just saying 'must be lupus'.
Any thoughts are appreciated!
