Overclocking by only changing multiplier - core voltage on MSI g45 z87 board. Voltage set on adaptive/ dynamic. Im running on 8.1 preview so the os is a bit unstable. Test runing cinebench:
Stock 4670k
29.5 fps/6.31 pts
temps hitting 71c
4670k @ 40x @ 1.14:
29.56 fps/6.77 pts (7% increase in pts)
temps hitting 73c
4670k @ 41x @ 1.145:
29.78 fps/6.95 pts (10% increase in pts over stock)
temps hitting 75, 76c.
4670k @ 42x @ 1.145:
crashed on cpu test.
4670k @ 42x @ 1.15:
29.87 fps/7.10 pts
temps hitting 79c
Note: Even though i set up voltage, system automatically adds 0.005 volts, so when i set on 1.145v cpu-z is reporting 1.15v, so the offset is 0.005.
Note2: ambient temps are ~30c
