I've just had a problem with this mobo, have had it installed for a while and has been rock solid overclocked but this morning I powered on and there was no video output

On looking at the mobo display the code showed 9A
No beeps or anything

I tried clearing BIOS which made no difference
then I tried without the GPU and I got beeps, so I thought maybe it's the GPU
tried another GPU no difference

Looked on the net but it seems like most people have RMA'd the mobos

Then I thought I'd try changing the PCIe jumpers to the 8x configuration and suddenly it worked
Put it back to 16x and didn't work again
So now I'm on 8x and it seems to be working ok.
Not sure if anyone else has had this or not might try a different BIOS altho it has been working for 3months on 16x
