DDR memory test failed.  Resetting the router ...

I tried to contact cisco TAC, but i need a re-seller contract number to place a ticket, i do not have a re-seller contract number as my router was bought more than two years ago.

I called cisco support and they told me to contact my re-seller, my re-seller told me to contact cisco so i am in a eternal loop of forwarding phone calls...

Any one have any idea on how to solve the problem ?

Any help is highly appreciated!!

Thank you guys

You need to buy some new RAM. –  smithian Oct 26 '12 at 12:39

It seems that the DRAM cannot be replaced because the first 128MB are installed on motherboard. I would call back Cisco and try to push on their side some more. They are usually pretty good about replacing hardware issues even if there is no support purchased.
