only 5xx cards are involved with voltage issue, all my 4xx cards are downvolted and working fine with latest beta of MSI AB

If you have Sapphire, use Trixx to undervolt. It will show 0 for cclock and memclock but you can control undervolting and fans.

Been running this driver for almost 2 days. Most stable/accurate effective hashrate I've had since starting to mine.
If ethermine would stop having problems it would be even better.

Try Watttool. Also there is a new version of AB supports this new driver patch.

I've tested this on all my rigs and at first glance all seemed great.

I did have to bypass windows not allowing me to assign a unsigned software.

My hash rates appeared to be the same as before the nasty Dag creation started.
My power usage is the same after under volting.
My REPORTED hash rate to the pool of course matching my Rigs hash rate.

BUT here's the kicker my effective hash rate on the pool is about the same if not a little less than it was before applying the driver.  So my question is this.
Is the driver merely creating false readings on the cards with no actual effect on total shares submitted to the pool much like when you think you have found the golden card that reports a hash rate of 45Mh/s when in reality its only hashing at the same speed as the others.  Had the new Driver running for 7 hours now ....so of course I need test some more just incase its the pool on a go slow....although it normally only takes a couple of hours to get fairly accurate readings.

one of these is great to use they don't cost much but only work in 110 lines you can search the UK site for one that works on 240 line but good luck getting it shipped to the US if that's were you live . some kind safely issue won't allow it .

my bad

but direct pulling into a 240 so far there is not one that it buy able in the US the buy able US sold one only plug in to a 110 wall plug the above monitors your hole house.

i found a way to speed up multi gpu i removed all amd drivers and disabled windows auto driver feature then i installed 16.10.3 for my r9 380x , 16.10.2 for my rx 480 and 15.12 for my 7950 from device manager.

With which program i change the parameter for amd on Windows ? .

If you guys look at GPGPU Benchmarks
http://www.anandtech.com/bench/GPU16/1512

You will notice that the 480 8GB will at max be 20% faster than the 290 under full optimization.

Comparing the results


480 8GB - 120MH/s
290 - 107MH/s
280x - 83.3MH/s
7850 - 45.5MH/s

Using the same ratios that leads to Claymore software

Nano - 98 Sol/s <- should be around here Optimally
Fury X - 96Sol/s <- should be around here Optimally
480 8GB - 96Sol/s <- should be around here Optimally.
290 - 75 Sol/s
280x - 55Sol/s
7850 - 30Sol/s

We are FVCKED if some developer released a Optimized Nvidia ZEC miner however because if its released and uses a similar hashing algo as Claymore then...

GTX 1080 - 262MH/s
GTX 1070 - 224.4MH/s
980Ti - 213.6MH/s

Converting to what we have now


GTX 1080 - 183Sol/s
GTX 1070 - 157Sol/s
980Ti - 150Sol/s


Thank god all the Nvidia miner devs are greedy and keeping everything PRIVATE.
