I've just assembled a Gigabyte GA-965P-DS3, E6400 and 2 x 1Gb PC6400 Geil RAM (4-4-4-12) system but it does not want to overclock. Any FSB higher than 275 (a mere 3% increase!) and it just won't POST and I have to use the CMOS reset jumper. I have tried:
1. Following various guides, such as http://forumz.tomshardware.com/hardware/Guide-Overclocking-E6300-E6400-DS3-Mobo-ftopict201220.html, to make sure the BIOS settings are correct and only the neccessary things are enbaled
2. Raising the voltage of the CPU, RAM and motherboard
3. Taking the CPU / RAM out of the equation by lowering multipliers so they run slower than stock, together and on their own
4. Running two loops with memtest86 with no memory errors
5. Reflashing the F10 BIOS
6. Removing all unneccessary components such as the sound card, all SATA connections etc
System still refuses to POST above 275 MHz FSB. What a royal pain - can I conclude the motherboard is to blame or is there anything else I can test?
