So my 7970 o'clocked to 1050 just broke. Was running it with diablominer in a MAC pro.

It will stop the machine from turning on sometimes, and if I do manage to get it on, it will mine a little, then the fans will go crazy, mining will stop, and the computer won't turn off unless unplugged.

What's up here? A chip broken?

Only been using the thing for about 3 weeks Sad

It's running from an EPSU (corsair 600).

I also have a 5770 in there which is continuing to mine me roughly 1 btc a year......

Any tech advice would be much appreciated.

Additional info: underclocking doesn't help. Same issue after a random amount of time.

Have also tried changing pcie slot to no avail.

Fans go crazy? Been there done that. It's basically the card losing power while mining. For me, it was the vibrations + loose connector.

This is about the 7th thread I have seen in the last few weeks about broken 7970s.
I also have a 7970 and it runs hot as hell. Don't trust the temp readout in CCC. Mine runs so hot it will burn you if you touch it but it reads a cool 60c in CCC.

You mite have a bad power connection or PCI connection.
EDIT: or maybe just maybe a bad PSU. check all your pin connections to make sure they are snug.

Thanks very much. This has given me some hope. I am running it from an external psu, maybe I will try running it straight from the logic board, though this has risks on a mac.

In fact I don't think I can. It draws too much power. The mac pro is only capable of providing 75w+75w+75w = 225w. The 7970 can draw over 300w. Sad

Get it replaced.

Find local shop which sells the same video card buy new one, return the old one saying it broke.

2/5 of the giga 7970s I have burnt out, rather, sparked out.  They shot sparks on start up, and you can see scorched circuits if you look closely.  RMA ASAP, if you can.

If you have warranty RMA it, if you don't look around if someone in your area fixes GPUs.

Next time, check the temperatures in GPU-Z, it shows data from more sensors than most software (I think only Aida64 can compete with GPU-Z in terms of GPU sensor reading).

The GPU core could be running at low temperatures but you don't know (or you do but you didn't yet tell us) whether the VRAM or VRMs weren't getting too hot.
