Upgrading Ram, System Failed to Boot

[Takanaki]

I bought http://www.overclockers.co.uk/showproduct.php?prodid=MY-012-AD from OCuk and just tried installing it this morning. I removed my old ram, two sticks of 2gb Corsair memory and put these sticks in the same slots on the motherboard.

http://www.asus.com/Motherboards/AMD_AM3/M4A77TD/ This is my motherboard, and the exact model I bought is on their approved vendors list.

It's the first time I tried installing some ram myself, so I wanted to know what could be wrong or if it's a component error? The system did not boot when the new ram was in, but when I took it out and put the old ram back in it's working fine again.

Regards,
Taka

I will try again tomorrow, all the settings were on auto detect for the RAM before I tried (as far as I was aware).

If you could let me know where I set those values I would appreciate it. Will update with success/failure tomorrow ; )

Thanks.

I tried changing settings in bios, system still wouldn't boot correctly. Have reverted to original settings and put in old ram for now.

Spoke to OCuk and they'll be sending out a return thing soon. Any suggestions on what RAM to get instead of this one, or should I get the same again and hope it was a one off fault with that batch?
