No post with new 78LMT-USB3 and AMD 965 BE

[DSLA]

Hello,

I wonder if anyone can help, I've just installed a 78LMT-USB3 rev 4.1 motherboard with an AMD 965 Black edition CPU bought from Aria and my system will not post, no keyboard lights and no VGA with either onboard video or add in graphics card. All fans are spinning.

Upon checking the CPU compatibility list (Which I should have done before purchasing!) I see this CPU is not on the list and this may be the cause of my issue. However the board does seemingly support other 125w CPUs including the new bulldozer range. I saw the board supported 125w CPUs and with the 965 being an older processor presumed I'd be fine!  

Does any one run this configuration themselves or know if this board will support this CPU? Do I need a BIOS update?  Should the system still boot and give me an error about an uncompatible CPU? I'm using a OCZ core X stream 500w PSU and 2 x 4gb Exceleram. I've tried re-seating the CPU, trying 1 stick of ram in different slots, clearing cmos with jumper. I've not got any sata/IDE components attached or any add in boards. Unfortunately I've no spare components to test if the board/CPU/RAM are working. If I can get away with a BIOS update I could buy a sempron CPU and flash it.

**Update**

Connected the pc speaker and it is giving off continuous 3 second beeps which on googleing is consistant with a CPU problem

Any help would be much appreciated

Lets see if i can explain this. For AM3 processors this boad only supports 95 watt processor in order for it to support the processor you have isnt possiable even with a bios update which their wont be one as yous is a AM3 125W.

Now if you step up to a Bulldozier it will support a 125 watt chip the reason being is the way the processor handles the PWM. Common misconception is that because the bulldoziers say 125 that the board handles a 125 watt from a previous generation CPU.

You chip will use 125 to 140 watt in reality where because of the internal regulation of the bulldoziers it will in reality will never use more than 125 watt on a 32nm die.

Two choices change motherboards or the processor. Your computer isnt going to boot with that processor.

Thanks for your reply, I think i'll just get another motherboard and make sure I check the CPU support list this time.
