Hi guys, looking for optimal settings for an r9 295x2, could please someone share? BTW what temps are you getting? Underwolt settings vs hash power? BR Ass...

well you can check out this thread right here : https://bitcointalk.org/index.php?topic=1424132.0 But they can get pretty power efficient, I dont have one myself, but I think its on par with or just a little higher than the efficiency ratio of a rx470, which are really good for efficiency. If you are looking for watts to hash, then for the price you can buy the GPU, I'd say go with the new generation. Sweet, thanks for the link! I currently have 2 RX480s and a 7970 (trying to replace with a 480 or something more power efficient) on ZEC and a GTX670 and R9 380 for ETH. Looking for best watt to hash ratio.

Best watt to hash ? Well compare with a rx470. For example, as read from my APC backup, msi armor 4g rx470, mining ETH (zec is about 10% less watts), I get 28.1mhs with 110watts. So thats a ratio of 3.9w/mhs or .255mhs per watt. You could bring the power down by a few more watts if you were really inclined to do so. I think thats pretty hard to beat I think nano can be even better but also consider the buying cost. Anyways, i'm hyped for the next zcash version update

Well...I would choose the Nano honestly, for the low power usage and there are very nice mods publicly available for it. Fury is nice too, but if you can choose a fury x...which is the same thing basically but more CU's. Keep in mind a nano is really small form factor compared to a fury, so its much more convenient too. Pretty sure nano has higher resale value too.
What is the hashrate on the Nano's anyways? Curious since I am trying to upgrade my rig to more power efficient cards. 5x nanos underclocked and undervolted 2000 sol/s 900w @ wall

Try grab them 2nd hand so you dont lose value too much when vega releases... iv seen figures of over 450 sol/s per gpu when on full throttle (max overclock).. one of the best amd gpu's for zcash without a doubt

I take it the 480 of that same series doesn't do quite as well for power efficiency? Or have you tested with that one yet?

I haven't tested as much, and only with a different brand. I dont have an armor 480 But from What I see, instead of 28mhs, you get 30mhs. Instead of 110w you get 130w. So 10% more hash, 20% more power used. I could be wrong, this is from memory. I can't really explain it either. I think the 480 draws a lot more power for the memory side. Maybe someone who has info on this can chip in

I'm not sure why this started all of a sudden but my rigs keep auto updating to the latest amd drivers. I have clicked the "do not auto update" button when I install the drivers and also have deleted the amd updater that gets added to the Task Scheduler but they keep auto updating. I have windows update turned off also. Anyone have any idea where else there could be an auto updater hiding?

Happened to me before as well. I needed to be on 15.12, but Windows 10 kept automatically installing the latest drivers. Imo the worst thing about Windows 10 is the forced auto updates. In the search bar type gpedit.msc Go to Computer Configuration > Administrative Templates > Windows Components > Windows Update Click on Configure Automatic Updates, disable it.

I can recommend coinotron for Zcash, even though hashrate is smaller. PPLNS is decent, and they have PPS at 3%. worker notifications, etc. I've never really had connection problems there (like dwarf, or sometimes coinmine). Plus its not flypool, so there's that @fr4nkthetank - I'm curious what's your problem/issue with flypool? Oh it was just a joke Flypool is fine, really. Some time back I compared coinmine/flypool/coinotron/dwarf and found better results at coinmine and coinotron, but then coinmine had connectivity problems. For a week or two they had really bad luck some time back, but that happens to every pool. ok : ) I use flypool since Zcash launched and the pool is fine, no problems. I don't have experience with coinmine or coinotron, and on dwarf I only tested Monero mining (but that was a +!%$ crap..).

You can not download the old version of the driver, such as 15.12, from amd official website. There's always only the last two versions. You will have likely downloaded from third-party resources. Be careful with this check files by antivirus, they may carry a risk.
