5 x Sapphire Radeon R9 290 Tri-X OC setup!

[SaRmY]

SGMiner is the logical gpu-only extension of cgminer, but maintained by someone else.  SGMiner fixes some very critical issues with cgminer and gpus.
I highly recommend it, especially if you have 7950s.  My WUs have never looked better on them with the optimized bins.

Why are not recommended for HD 7950 mine with cgminer?
I don't know but 4 of my 9 hd 7950 died mining with cgminer with no aparently reason. I had a moderate overclock and the gpu's never exceeded 75º.
Now these gpu's don't show display. When windows go to boot the failure cards don't show display and the same in Linux. I only see screen until the motherboard bios logo.

please I need cfg for sapphire cgminer 5x r9 290 tri-x oc

For my 4 xfx reference blower model 290s with 100% uptime since rig inception in sgminer:

Code:

--no-submit-stale -I 20 -w 256 --thread-concurrency 20481 -g 1 --gpu-fan 90 --gpu-powertune 20 --gpu-engine 965 --gpu-memclock 1500

This worked like a charm in sgminer.

Thanks!

Have you got 5x 290 Tri-x setup yet?

Interested to see if they are stable, as the R9 290's are hit and miss with more than 3.

bump

I have 4 running stable paired with 4GB of ram and the cheapest LGA1150 CPU.  
Pulling a consistent 945KH/s+ on 3 cards, and over 900KH/s on 1 card (which won't take the memory overclock... yet), straight out of the box with no burn-in.

I see no reason I couldn't add a fifth (other then that I can get other 290 cards for cheaper, so I won't bother)
