I am having some real problems getting these 560's to do any sieving -- The Gigabyte is managing to hide from PG (GPU not found) -- I can see the damn thing clear as day from where I am sitting and it is running a monitor!!! -- (Probably a driver issue I guess) -- The Galaxys I have renamed -- Dead - Dying & Doubtful -- I am nursing 2 of them through a sieve unit each underclocking to get the heat down -- strange- cause I cleaned and re-pasted all thermals & fans are ok

I am thinking it might be from the flogging they got last time I was sieving on PG -- O'clocked to the max & running 24/7

I might be looking for GPU's sooner than I thought.

Massive condolences to you Matt. In time you'll be back with an even better machine. Calculate what credit you need to make up the deficit :)!

I think I may have self-diagnosed the problem. I started to pack up my rig for shipping, and I realized that I've been running my power supply upside down for the last four months, with the exhaust fan pointing DOWN directly into a cushion mat!

With no good airflow it probably ran hot and burned itself out.

D'oh!

my dual GTX460 may have just crunched its last.

It just powered off for no reason, and won't come back on.

Unfortunately we are moving overseas in a couple of weeks, and I don't have any troubleshooting tools with me. So I don't know if it is a bad P/S or something worse. I was able to verify it's 1) not the outlet, and 2) not the power cable.

I'll ship the rig and try to figure it out in a month or two when our shipment catches up with us.

That rig is almost at 100,000,000 PG cobblestones, which is a milestone I was really looking forward to. The two WR-GFN WUs that it was working on will unfortunately expire.
