Yup !  Its an awesome project really.  His SGminer fork can also do other coins, but he's mainly concentrated on ZCash.  I'm waiting for the next update, he is doing god's work

I have a 6 Fury rig that runs 1650W at the wall with Gold rated PSUs (stock bios).  When I load an 'eco' bios on the secondary switch the rig runs 900W at the wall.  You may be able to get away with a single 1600W PSU, but if you're going to drop that kind of cash you may as well pick up a 1000W G3 and a 800W G3 for the same price.  You'd get a bit more overhead on the PSU to keep you under 80% (stock bios) and even get close to your 50% sweet spot if you under-volt.

Edit: The multi-PSU approach with new generation G3 also ensures that every single VGA cable has an 8-pin power plug.  An EVGA 1600 G2 only has nine (9) 8-pin power and then five (5) 6-pin power.  You'd also have to purchase a few adapters if you go with a single 1600W as you will need twelve (12) 8-pin for a 6 Fury rig.

Please don't forget Linux!!

All my ZEC rigs just locked up all at once. No idea if the pool died or not but it was a hard reset.

Had to physically yank the power cord from wall and replug.

Upon checking log, they all got the Temperature 511 error. So I dont think its a hardware issue since every rig got this error all at the same time.

Anyone got this issue also?

ROI in a few months - of course not. But in maybe 10 months or a year is doable. Depends on what coin will follow and what electricity rates you are paying.

Anyone know where I can get the 'ECO' Bios for AMD Fury cards and a bios flash software?

I thought of that but my ETH rigs were running fine. Two rigs were even on the same breaker. The ZEC went off the ETH stayed on.

This is some software issue. Maybe it only happens when a pool dies.





I had this error before on some rigs, I assumed it was a riser or gpu. But this happened on all my ZEC rigs at the exact same time. Its definately software related. All of them got that same error at the exact same second according to the log

This is a Zcash mining thread (see it in the thread title?). Your question is off-topic, and there's actually an entirely different forum topic for coin market discussions. You may say "big deal", but people coming to the thread really don't want to wade through pages of posts, like yours, that don't have anything to do with the subject of the thread they came to read.

I see about a 15% increase on a Radeon R9 380X (175 h/s vs 200 h/s)and about a 35% increase on a Radeon HD 7870 (125 h/s vs 175h/s) using Optiminer. However, I've found Optiminer to be far less stable than Claymore. I've been having to restart it every 3-4 hours and I'm also seeing "block" pixelation pretty consistently while Optimer is running. I do not have these issues with Claymore and for that reason I've switched back. At this point in time neither application is perfect, so pick your poison. I'm hoping Claymore's next release can match (or exceed) the speed of Optiminer while remaining a stable build.
