Check what DAG are you using for test. 30.5 for RX480 usually for low DAG like 50 or less, now for most of coins you have 200+

The easy way is to download fresh Hive version and set up from scratch.

XMR-STAK 2.5.1

Just the same problem with the next update, 0.5-81

After hardware reboot 0.5-80 version is reported, rig working properly so far. The only drawback is that "selfupgrade succsessful" message was lost.

The rig went offline. No connection for 5 minutes, going to perform hardware reboot.

I still have the problem. The rig wan't update to .79 even after .80 is announced
I'll run selfupgrade and report results.

I am experiencing update bug with last few HIVE versions. Few days after Telegram notification I am unable to update. The update button is highglighted but after depressing it shows "you have the latest version" and do nothing. It is a bit annoying just before today's Monero fork.
Please look into it.

Still have a bunch of the cards, still working without any problems. Due to high power consumption (I managed to stay within 250W for Monero7 and do not allow more then 85C for core) I have to run them only in night when we have special (50% reduction) electricity tariffs so it is surely not the best choice for now. I have better luck redoing termal paste - usually 10 degrees core temp reduction :-). When Claymore drop support for them I seek for alternative and with help of XMR-STAK community we found a way to work around the bag in 15.7 AMD drivers that prevented decent performance for HD6xxx cards. Going to use them to heat my garage in winter - no profit but no expence also :-)

As for now XMR-STAK 2.4.7 is a bit faster for Antilles GPU then the last Claymore that was compatible (9.7, now obsolete). But it really need fine-tuning and proper driver selection cause latest drivers for Antilles (15.7) do not report proper memory size. The problem was discussed in deep at XMR-STAK github https://github.com/fireice-uk/xmr-stak/issues/472. In short you have to use 14.4 driver for optimal performance. Please note that it is impossible to use HD69xx and RX in a single system with optimal performance.

No way the obsolete cards will be again compatible with the miner. Feel free to use xmr-stak, up to date it is still compatible with a few tricks and driver 14.3 .

The last Claymore version supporting Terascale is 9.7. Unfortunately it do not support forks that occured this year.
At the moment you can use other miners for Terascale GPU in case you have free electricity and do not care for hash per watt value.
Try xmr-stak for example.

A small bug report.
I found that my ETH addres for referral payments is empty. I was not sure that I entered it at all so I try to do it now but without success. "Save" button do not seem to do anything. When I revisit the page later the address line is again empty :-(
No big deal, just five referrals for the moment but please add it for you "to do" list.
Thanks a lot for your great product! New version is definitely better.

2Gb is enough for mixed AMD|NVIDIA rig with 5 GPU. At the moment I am using RX580, 2xRX570, RX560 and GTX1050TI in single system with 2Gb memory. I have 4Gb handy but do not feel any need to mess with good working system. I even run second miner for CPU - just to be sure that the system can handle the load but CPU is a low-end Atom so it make no sense for real.

I am running CDE v.11.8 with 2Gb Ram since the version is available, no problems. Just use Linux :-) and forget all this windows crap about pagefile, disabling updates and new drivers with performance issues. No-brainer for Linux noob - HiveOS with Web managment console and free for home mining up to 3 rigs.

You can start with info how much Xeon Phi you are able to run in a single system and what is required to run more than one Xeon Phi coprocessor in a system.

Do not assume that anybody tested the stores from the list. I also want to know in advance about any scam but it is really not possible. For example no one can oversee when a store is sold to different owner.

I'll d'like to point that single 570 tops 900+ H\s, not 600 as in the picture. So assuming all other calculation are correct we get a lot better average ROI for 570 :-)
Also I always keep 570 under 100 Wt, 200 Wt from the wall probably only for single-card computer with shitty PSU.
Surely it is by far less energy efficient that ASIC but let's stick to realities.

A great insight into current mining from an ASIC manufacturing team. Worth reading IMHO.

You can get natural gas for as low as $100 per 1000 cubic meters, it is usually 10 000 kW*hours - $0.01 per kW*hour
Modern high-power turbine generators go as far as 42% efficiency so we can expect something around $0.03 per kW*hour
Not bad at all. But you should seriously consider how long it will take to ROI. If you have some need for secondary heat output (say hot-water for sale) it helps a lot in terms of ROI. Unfornutaly at the moment we got $300 for natural gas locally and $0.05 for electricity so I have no chance to proof my studies for-real :-(.
