I read the E6700 overclocking review here at TechSpot https://www.techspot.com/article/13-intel-core2duo-e6300-e6700-overclocking/ and figured it was good enough for me to achieve 3.5GHz but cant get even close. My mobo P5W DH Deluxe and E6700 CPU are the same as in review and only the memory different being also Corsair is PC6400 XMS2 dual channel matched sticks 2x1GB. This where I am at the moment and desperately wanting to figure out what is stopping me from achieving the 3.5GHz or better as achieved in the reviewed test. FSB: 330 RAM: 825MHz PCI Frequency: 100 PCI Clock Sync. Mode: 33.33MHz RAM Voltage: 1.95v RAM Timing: 5-5-5-12-5 Vcore BIOS Setting: 1.5v Vcore as reported by sensor: 1.46-1.48v FSB Termination Voltage: 1.4v MCH Chipset Voltage: 1.55 ICH Chipset Voltage: 1.2 CPU Temp: 58-61 spiking occasionaly up to 63 Have rebooted the rig so many times with so many different combinations of FSB termination, MCH, ICH and it doesnt seem to make any difference at all. The only thing that has been resulting in longer stress test runs is increasing Vcore. This is why I am already at Vcore 1.5 which has increased my temps as well. I stress test with Orthos and the above settings will normaly give me about 2-4 hours before Orthos fails. This is driving me nuts. Any help would be much appreciated.
