I have a asus gtx 650 ti boost direct cuii gpu.... I need help in unlocking the bios with kepler bios tweaker 1.27 to unlock voltage and power limit...
I Just got a new 4770k. I was fully aware beforehand that overclocking isn't as clean and easy as a sandy bridge or even ivy bridge CPU, but myn seems to be worse than I've seen on any thread. With the stock heatsink, my temps at stock were getting to about 37-39 idle with 85-87 load. Verified it was seated properly multiple times, and finally switched to Arctic Freezer Pro, with 35 idle 83 load, then finally to Corsair H80i with 29 idle 69 load. Ambient temps only about 20c, high up in idaho.. Now I have been trying to overclock, but no matter what I try, at just 4.2ghz, it will be completely unstable at anything under 1.295 vcore. Everyone else seems to get "unlucky" ones that take 1.20v at 4.3ghz. What am I missing? I've tried not messing with the ring ratio / voltage, and also putting ring ratio to a variety of voltages and clocks, but no change in stability. I cant go a hair above 4.2ghz either without being unstable, and even with the h80i, my temps at this voltage are hitting 83c at load. MSI Z87A-GD65 motherboard, 16b DDR3 1666mhz 1.5v ram kept at stock voltage and clocks.

(Generated by PCPartPicker 2013-06-02 14:20 EST+1000) I've recently updated my system with a new PSU, Graphics Card and Ram. Everything else in this list was happily running until a few days ago when it randomly shut off. I assumed it was my old PSU as I'd had some trouble with it before and it was due for an upgrade anyway. I tested that the PSU was powering on the system (minus the graphics card) before installing it and everything appeared to be fine. I didn't actually test it with a monitor though. After installing everything in the case except for the graphics card I decided to boot up the system to remove my old drivers before installing the 7970. However, the system restarted after less than a second. Upon showing something on the monitor I was informed that there was a CPU over voltage error and was given the option to go to the bios to change my settings. I reset everything to defaults and tried again. This time the computer restarted roughly twelve times before I switched it off manually. I tried again only to be told that in addition to there being a CPU over voltage error that Surge Protection had been enabled to protect my motherboard from a faulty PSU. So far I've considered that either the CPU, motherboard, PSU or some combination of all of them is at fault and that I will have to return something or everything. What am I looking at here? Is everything dead or can I salvage something? Thank you for your help, I'm kind of freaking out here. I really appreciate any thoughts you may have, even if you're not 100% sure.
