I've having a hard time overclocking my opty 165, I can get it to run stably at 2.15 ghz, but if I try to push any higher I have real problems, it will refuse to even boot into windows. My temps are great, at 2150 ghz I Idle at 30C and peak at 43C. I can run run three instances of stress prime for upwards of 8 hours just fine, two instances devoted to either core running in the cpu stressing mode and one with no affinity set running blend mode. For some reason thats the only way I can keep the cpu being utilized 100%. Anyway, where I'm headed is that I'm thinking the power supply might be part of my problem. I have an Aspire X-Dreamer case and am using the power supply that came with it, which is a 420W power supply. I'm using an ASUS A8N5X motherboard and hence have PC Probe, when I run it I see that the 3.3volt gail is consistently 3.31, the 5 volt rail is typically around 4.84, and the 12v rail moves between 11.8 and 11.98. These figures are with no overclocking applied though, running at completely stock settings just as a baseline. When I overclock, the voltages seem a bit less stable with the 12V rail being inclined to dip even down into the 11.7's. I dont know if this is the problem or not, but I figured some advice would do me well! If ya'll think that it could be PSU related, I am considering swapping to this: http://www.newegg.com/Product/Produc...82E16817101518 Cost is of course a concern, I dont need anything ridiculously expensive. I use my computer for heavy photo editing and batch processing, I occasionally play games but not really competitively or anything. Thanks!
