Got this mobo and installed it,

the LED lights come on, and the fans power on, but there is no screen displayed. i know its not the graphics or memory cause ive put them in another board and the card works. Anyone got any ideas?

cheers for the help

Sorry i thought the blue was the top one, i placed it in the top one and the 2nd one.
it comes up with a 1D
ive taken memory out and tried it sepratly in all the different slots.

would taking the battery out of the CMOS help?
 
ive been looking to get this motherboard and been looking at the manual, check the memory it can except, it maybe your ram is not been excepted by the board, ive herd people have problems from this and the board would not allow anything to boot meaning no hardware could start up like the graphics card ending up with no screen.

Have a good look through the manual and if anything do a search in google for the led D1 or w.e
 
Try one stick of ram... try it in each slot... one slot at a time until it works... report back with your results...
 
i think i know what the problem is.

i think its to do with the RAM valtage i think some forums were saying if its below 2.2v it doesnt really work. and something to do with the N/B and S/B heaters, theres crap between the coolers and the chip's tthat makes it over heat too much and replacing it with Artic silver takes the temp down 10-20c. anyone else experience this?

im away from my comp for a few days anyone tried this and it worked etc
 
What voltage is your RAM rated to run at? It's a possibility that the motherboard's not supplying enough at stock, I've heard of it before. The thermal pads under the heatsinks shouldn't be an issue unless you're overclocking so I'd discount that theory.

as above my 680i board only gives 1.85v to my ram, it needs 2.1v - won't boot properly without manually setting it...

Yes! Exactly the same problem on mine. I found that I could not get the system to boot at all. The board started up and then within a fraction of a second it would stop. If I tried this for 4 or 5 times, it would eventually start ok and run fine all day. The very next morning, it would do exactly the same thing. I spoke to Technical Support on OcUK and they said set the RAM voltage to 2.1 and it would solve the problem. I did this 3 weeks ago and it has worked properly ever since.

You might want to test the temps on your ram chips though, mine were too hot to touch, got a dominator cooler to blow on them and they run cold now :)
