I'm relatively new to tweaking and building. I built this system as a workstation for audio production/CAD/web development, and I use a large portion of all that RAM as a RAMDisk for audio applications and plugins. I actually put together this system a few years ago and never bothered with trying to overclock or even make sure that my memory was actually operating at its advertised 1600MHz frequency, lol. Of course I discovered that the RAM was running at 1333MHz, and that's when I started digging into the BIOS. I became curious about overclocking and have been playing around with optimizing my system for the past year or so. The best I have been able to achieve is a 4.3 GHz overclock by maxing out the multiplier to 43 and leaving the BCLK at 100. I also had to adjust my RAM timings to 10 10 10 30. VCore is 1.32V, and I have a feeling that I could easily go lower. Temps are 30C idle and 45-50 under load depending on ambient temperature.

Any time I deviate from this scheme and try to increase BCLK, my system will fail prime 95 blend within 30 minutes and often times within just a couple minutes. I have tried many permutations of all of the different voltage options, power management, CPU multiplier, BCLK, etc. to no avail.

As I said, I am new to building and tweaking, so I could be totally off the mark, but I feel that my 3820 chip is fine and perhaps I need to relax my RAM timings and/or increase DRAM voltage to keep up with the overclock. Here's what G. Skill thinks about trying to overclock my particular RAM:

What do you guys think? I can get screenshot of my current BIOS settings if needed.
