My son noticed the Auto setting in the bios was not running the DDR2 at the expected 800Mhz. So he manually set the speed to 800. After that the system failed to boot even after removing the bios battery for >1 hour as recommeded by Intel. During a journey for repair the PC was destroyed by a vehicle.

We set up a second DG965RY with the same memory it too was running slow in auto but Windows XP was running fine, so again the settings were manually adjusted and bingo no boot, ever. The mobo just cycles on and off sometimes it continues to run. There is no video and no apparent keyboard or drive life. Currently it is being tested on the bench with no front panel connections. A jumper is used to simulate the start button.

The memory has been tested on a Gigabyte mobo with Memtest X86 and completes all tests without error. The 5V , 12V and CPU voltages appear to be normal. Two processors have been tried with no change and two graphic cards have been tried with no change.

There is something horrible about these Intel boards. Gigabyte mobos from my experience prevent any failure of the bios due to inappropriate settings and recovery to default values.

Is this mobo now junk??? I cannot see how a bios recovery will work using a CD etc with apparently dead devices. The bios chip is not a plugin one. Not impressed by the Intel implementation.

Has anybody a clue how this happenings and how to restore operation?

Try Ising the memory at DDR-2 800 mhz setting and changing the CAS latency to a higher number and see if the RAM can function with the motherboard. If that doesn't work return the RAM and buy Mushkin-Corsair-OCZ-Geil-Kingston HyperX-Crucial Ballistix! Anywys what name brand RAM you using is it generic?

Thanks Gunblade. I did state memory has been tested 100%. It has also run perfectly on this motherboard before it self desstructed. I cannot change any settings. I did not explain that I cannot even get the bios up. The bios self destructed after changing the settings as originally stated. Unfortunately the bios chip is not the plug in variety so that it is not easy to flash if nothing operates. Only the fans run and all voltages are OK
