GA-965P-DQ6 775 keeps rebooting

Maybe your board just don't like having all DIMMS slots populated. I would suggest running 2x2 gig modules.

Sorry I missed that all your memory slots were populated. Have you increased the Northbridge voltage slightly to compensate for the extra loading?

The faulty RAM was indeed the problem.

Corsair are replacing both modules by return of post, which I'm really happy about since they were purchased 4 years ago!

Thanks again for your assistance.

[Dark Mantis]

Oh, good outcome. I am glad that everything has worked out for you.

Bad news.

My Corsair RAM purchased in October has now failed after 2 months use. As I purchased a new Corsair PSU at the same time, I'm wondering why the memory has failed after such a short time.

I have never overclocked or altered any memory settings in the BIOS.

Does anyone have any clues as to why this has happened again?

[Dark Mantis]

If it was run at the recommended setttings and voltage then there is no reason for it to have failed apart form maybe it was just a fault waiting to happen. RMA it and you shouldn't have any trouble as they warranty it for life and are normally good when it comes to replacements.
Make sure that you RMA the complete kit though not just the faulty module.
