Cisco 3945 Router - FATAL ERROR: ERR_DDR_DQSOFFCAL

We have a 3945E router which had been isolated from the network due to recabling (but not powered down) for a few weeks. When it was reconnected to the network the links did not come up and the router did not respond to console requests (not recognized at all / no output). It was decided to power cycle the router, this caused a single line to appear on the console-   "FATAL ERROR: ERR_DDR_DQSOFFCAL"  there is no further visible attempt to boot and no other response or indication. An additional power cycle yielded the identical result. All port indicator lights on the router are off. I could not find this fault or anything remotely similar on this forum or Google. Any help would be greatly appreciated. Thanks, Mike

If it doesn't help, try RAM module from other device.
