Hi, I’m having real problems with this motherboard (purchased yesterday) but I’m unsure that it is the motherboard and need advice.

Some background:

My original system
Asus P5nt-deluxe 780 chipset with Q6600 Kingston 1066

After getting two dead boards this setup would OC but would have problems, thought it was the ram so I purchased a set of OCZ Flex XLC 9600 still had the same problems and in the end killed the board trying to volt mod it.

Second
GA-X48-DQ6 with the same Q6600 and OCZ Flex XLC 9600

Would OC and pass 12hrs of prime but after a few start ups and shut downs I would get the constant reboot at post and the system would revert to its optimised settings. This would even happen with a 200 MHz OC and about 1.35v (1.28v standard).

Third
GA-EP45-UD3P again with the same Q6600 and OCZ Flex XLC 9600, Purchased yesterday.

Wont OC at all even had the constant reboot when I changed the power saving features from standard. I purchased this board for its overclocking. I had read heaps of reviews with Q6600 needing less voltage and clocking higher. To make it worse when changing the mobos over I forgot to change my Riva tuner profiles and cooked my video card, lesson learned X48 clock video cards higher than P45, and it was water cooled.

In all of the above the ram was always under clocked far from its specs. I purchased a set of 1066 dominators which will arrive Monday but it’s looking like that isn’t the problem.

I NEED ADVISE PLEASE!!!!! To me it looks like the Cpu is the problem in all this but I’m just not sure has anyone had these problems or could I just have bad luck with mobos. At stock everything runs fine 24/7 gaming, benching, everything.

I’ve used OC profiles off forums for the same boards but could not get what they were getting.

The only two parts that are the same in all this are the power supply and the Cpu I don’t think it’s the power supply because no matter how many HDD or fans I plug in when the system is standard it runs fine its only when I OC.

Any help would be really appreciated.
