At the moment, I'm trying to overclock my E6300 with my GA-945P-S3 motherboard.
The problem I'm having is I can't get stable overclocks without overclocking the PCI-E bus. Like serious overclocking. To get past 2.4GHz I have to push the PCI-E bus frequency above 110MHz, and from what I've heard this doesn't seem right.
I've tried changing Vcore, FSB over voltage, DIMM over voltage and all that jazz, to no effect. It only POSTs above a 300MHz CPU Host Frequency if I overclock the PCI-E bus in line with the host frequency overclock (e.g. 100 -> 110 -> 115 etc).
My setup:
Processor: E6300 (1.86GHz)
Motherboard: GA-945P-S3
RAM: Corsair DDR2 XMS2 (667MHz, 5-5-5-12 timings)
Cooler on processor: Thermaltake Big Typhoon 120VX
Case: Antec Nine Hundred (2 x 120mm intake, 120mm side intake, 120mm rear exhast, 200mm top exhast)
PSU: Corsair HX620W
GPU: MSI NX 8800GT (factory overclocked)
Grease: Arctic Silver 5
HDD: 2 x 250gb
Theoretically I should have plenty of cooling, so I don't think that's the problem. Overclocking the PCI-E bus frequency worries me, and not being able to overclock without it worries me even more. Unfortunately, google hasn't been much help.
