Hi! I seem to can't overclock my E7300 over 3GHz specs are:E7300, 2+1GB RAM 800MHz 5-5-5-18 3-23-6-3, 9500GT 512MB NVidia graphics card and 945GCM-S ASRock MB
More aboutoverclocking barrier
I would bet it is the P945GCM chipset motherboard limiting you. P45 were the best LGA775 boards for overclocking. Really I am surprised that board even supports that chip.
well my setup is 3 years old :P thats 1st thing, 2nd thing is i can do max 299MHz x10, when i leave PCIE at 100MHz. But i tried doing synched OC and got to 3,2Ghz (320MHz x10 and 112MHz PCIE), but got a blue screen of death after 10 mins (system didn't overheat)
