Hello, I recently over clocked my Intel i7 from 3.06 to 3.43 and it seems to have slowed my computer down? Can I get some clarification on this if maybe my voltage would slow down the computer? I'm very new to over clocking so that's why I'm having this issue... Running stress tests with Intel Extreme Tunning Utility.
I'd suggest you use the stock BIOS settings and do the following:
W/ DDR3-1600 Memory , do a 20% OC
160 BCLK x 23 CPU multiplier = 3.7 Ghz
160 BCLK x 10 Memory multiplier = 1600 Mhz
The only change necessary for this is to set the BCLK at 160 and DDR3 speed at 1600 [Memory Multiplier at 10, leave everything else on Auto. Make sure RAM timings are at "what it says on the package". If that runs stable I would drop the CPU and DRAM voltages in accordance with procedures described here:
