JCE CNv8 you can get 900 on with 1120/1420
Thanks for the reference Wink
could you share your GPU config file content, i don't have this same card to bench myself, so i could add your config as a reference in my doc Smiley

I had 8 of these and had to RMA most of them due to attempts at repasting and also just GPU death in general
I've also had mostly bad experience with 290s. Had only 5 or 6 of them in total, and 2 or 3 went bad within a few months (all bought new). Haven't ever had such high failure rates with any other GPU series.

I think 900 is very fast. I can get only 600 when the core frequency is 820MHz. That is equivalent to 820 at 1120MHz.

What were you mining with them? If you bought new, I am assuming it was late 2013 and you were mining Scrypt which was litecoin.

From what I recall, the R9 290 was a complete power-hog with Scrypt and if you ran with stock voltage they pulled 350-400Watts per GPU easily and due to poor heat control, they easily burnt up.

Not sure what coins I was mining back then, probably scrypt (vtc and doges mostly, iirc) and other algos that made sense at that time, but never mined with stock voltage on any gpu and definitely not 290s - always undervolting. Maybe just got unlucky.

Also earlier there were not so simple risers as we have now. I burnt one R9 290x after incorrect connection of additional power to the riser. It cost a lot at the beginning of 2014.

Yes back then we had to use the ribbon risers.

I remember people had issues with the powered risers due to the +12V line being shared with the motherboards and the PSU +12V rail.

Basically you had to make sure the +12V lines were cut and weren't connected to the motherboard because if they were then you got a feedback loop because the motherboard +12V wasn't exactly the same as the +12V from the PSU, even if you used the same PSU. And it was a quick way to destroy a GPU, motherboard and a PSU.

These GPUs are still profitable mining Blake2b at 12c/kWh and Ethash too but the hashrate on these late DAGs is around 22Mh/s
