GA-P55-USB3 incompatible with 2x4 GB RAM? Weird problems

[lores]

After another 24 h, both rigs keep seeming to be stable. I suspect they are stable.
How can this be? I was convinced that the i5 760 was just an i5 750 with an increased multiplier (20 -> 21). But in my case, the Gigabyte motherboard - when used with 2x4 GB RAM - is obviously not compatible with my i5 760, but fully compatible with an i5 750...

 I really would pull Gigabyte into the picture with a detailed Email......you never know, nothing will happen if you never ask !

Hey there,

Is there any solution than RMA the motherboard?  I got the EXACTLY SAME issue as Lores', and my setup is GA-P55-USB3 with i5-760.

I may not be RMA it since I have used the combination for 2 yrs.

I've seen lots of reboot since I brought it and equipped with 2x4G G-Skill RAMs, then the reboot disappeared when another 2x4G Kingston RAMs are added.  Now the issue comes back as I added a Nvidia 660 graphic card few weeks ago...

ANY HELP IS HIGHLY APPRECIATED.

Thanks,
Jacky
