Recently, I've been trying to make my overclock more stable and energy efficient. I read that CxE can cause severe stability issues when stress testing. I disabled CxE, but left EIST on because the BloodRage needs EIST enabled to use turbo mode. I'm using BloodRage BIOS P09. CPU turbo is set to "Always On" in the BIOS. Using a program called i7 Turbo (it comes with Real Temp), I discovered that my multiplier was throttling when CxE was enabled, but not when CxE was disabled. However, EIST was on in both situations. It passed some decent stress testing: 1 hour P95 small FFTs and 5 passes LinX w/problem size of 25,000. BCLK is 195, multiplier is 19X/21X w/turbo, vcore is 1.32V, and uncore is 1.28V.
