Here is something I have come across. One of these last few BIOS updates changed something with voltages. When I first put my system together I ran Cinebench with no problems on my 1700 OC to 3.7Ghz on a cheap Zalman Cooler with Core voltage set at Auto. Not sure if it was BIOS 504 or 511 the first time I ran it. Now with 604 I start Cinebench get pretty much immediate black screen and keyboard lights go out, yet system still on and running have to restart or hard shutdown. Was able to get around it with voltage offset. Did they change voltage scaling not to be so aggressive? Anyone else have to adjust their overclock or set a manual voltage after a certain BIOS version? On a good note my Corsair Vengeance LPX 3000mhz memory has been cold booting and restarting pretty consistent at 2933 16-17-17-36.
Also can someone educate me on SOC Voltage? What's it do? What's it for? How does it help with overclocks? Never had to mess with anything else other than core clock in other builds. Just trying to learn and could not find straight forward answer on google.
