anyone here use paper wallets to secure ETHs ? I don't feel confortable to keep everything in Jaxx and Kraken, I would like to put some on paper for long term, but I don't know how to do it for ethereum. What are your strategys here?

True! I read a lot about the h81 having issues these days I have stopped doing 6 x GPU rigs, and standardized on 4 x GPUs and moving away from PCI-USB risers. Since Phil's recommendation on Biostar Z170 Racing, I have my 5th rig based on the mobo - very pleased with outcome and minimal issues. Overall rig cost makeup is also lower due to lower watts PSU and M2 SSD. Even the power switch is done away with because of the on-board power/reset built in into mobo. So, you have eliminated the expense of risers and power switches and gained the M.2(I love these). Are there heat issues with the gpu's so close together? Would that offset the cost of the power of the motherboard power usage? Ex. I can get 6 or 7 gpu's for 1 motherboard. 1 motherboard is xx Watts spread over the revenue of 6 gpu's rather than 4 gpu's. the 5 x rigs that I have based on the Biostar is so far the least problematic in my farm, and also the best performer for ZCASH. Temps so far is reduced significantly mining ZEC, vs ETH All of Biostar farm using Nanos are maxed and steady at 58-62 sols using v3.1 ... compared to 6 rig setups (based on Nanos) at most 48-52sols, and stresses the poor 1840 CPU leading to hang and unstable after running for few hours. I can also spread the power cabling/allocation better by not having too many power hungry 6xGPU rigs. My previous issues in power and trips was determined by my electrician -- too many 6xGPU rigs (1600watts PSU) clustered under one circuit (no thanks to 5x390s, 6x480s). My warehouse power has 3-Phase 63Amps, so spreading the 6xGPU rigs into 4xGPUs per rig evenly into 3 groups/phase will help ease the power distribution. The issue of 4 GPUs so closely together, is actually not a problem and with Claymore's good fan controls, all of the Biostar rigs at 75-77c. A box fan behind the rack also helps. All I did was use the same technique by Phil using those GPU plastic stubs, in between the GPUs - 3 stubs per rig. I have used wooden chopsticks too and its all ok. If you planning to have a couple of 6xGPU rigs - I think its ok, but if you have a farm.... 6xGPU rigs needs a bit more work, planning and expect power isssues. As for my case, I went for taking out all the items that will give me white hair like HDD/SSD (replaced by M2 and thumdrive EthOS), risers and big PSUs. are you using intel i5 6400 or intel i5 6500 as your cpus? they will give you close to 18h at 3 threads 22 h at 4 threads Very compact systems. Probably the most compact that I have seen! I am also seeing the benefits of mining ZEC - Higher initial profits, less power usage and less wear on the rigs. Thank you (and Phil) for sharing your rigs and opinions! I really enjoy this forum.

Guys,
Any good expectation from this CPU - i7 980X LGA 1366?
I found a MB sitting in the pile of computer parts in my garage

are you using intel i5 6400 or intel i5 6500 as your cpus? they will give you close to 18h at 3 threads 22 h at 4 threads unfortunately, the entire farm was built on ETH in mind, so CPUs were limited to Celerons 1840s for the ASrock H81 Pro BTC builds, and Pentiums G4400 for all the Biostar Z170 mobos. CPU mining ZEC is a tough call for the rigs now because CPUs are loaded with high load cycles to support Claymore's miners, even v3.1 still takes too much CPU cycle. My next project is Biostar Z170 + RX470s with i5-6500 or higher (if AMD Zen doesn't come out first) and leverage on some CPU+GPU ZEC mining.

minimum required for mining is SSE? no? having AES and AVX is a bonus and will give you more hash can anyone confirm?

LoneRangir is most knowledgeable on it here. But maybe somebody has practical experience I exchange my Celeron on Intel Core i5-4690K and now have 6x RX 480 Nitro+ it is giving me stable 17.3H/S. Whole rig ~370H/s with 710W from the wall

very nice pic Citronick! all clean
clean... is over statement Still have a lot of room for improvement. So many network cables, 6 network routers, separate power strip for box fans etc. Proxy servers still half done, Teamviewer and VNC servers still on old and slow PCs.... the list goes on, but keeps me busy. Getting those steel frame racks, gives some structure in layout and most importantly air-flow. Always direct air flow UP.... hot air goes up... best lesson so far... and gave me 3-4c reduction in temps. Also, good modded BIOS to low power (like Heliox on 480s) gave big difference in power consumption and temps. I also have recently invested in 2 x air blower/sucker? I am still figuring out the placement etc to get best ventilation for the 26 production rigs and 4 testing rigs

I am doing really well with 4 rx 470's and 1 i5 6500t close to 260h

Phil - I just used default command line fo Claymore and CPU miner. Should I change anything?

Should I change anything? on the cpu miner : if you put -t 4 on the end of the bat file it does 4 threads on an i5 four thread cpu or an i7 8 thread cpu I find -t 3 or -t 4 works well for i5 4 cores I find -t 5 or -t 6 works well for i7 4 core hyper thread. there is variation on i5's and i 7's and mob's but gen 4 and gen 6 are decent older ones are a little slower. my asus z170A board has a i5 6500t and it does very well with -t 3 or -t 4 at the end of the bat file

Phil,
Will play this evening
Clay's miner is awesome - v4.0 6x RX 480 + CPU = 450H/s
Kinda cool!

Have you tried without CPU see if you get more sol/s ? And are those stock or modded? I'm going to bring down all 6 card rigs to 5. To get those higher sol/s And upgrade cpus eventually

Does anyone know what is going on with ZEC shares reporting on flypool? I was humming along all day yesterday averaging about 260-270 valid shares per bar on their bar graph belwo the hashrate average chart but today I wake up and check it and the last 6-7 bard have roughly been cut in half... so averaging only about 135 per bar. I've got the exact same average overall hashrate of about 220-240 that is was running at yesterday and same <1% stale shares.
Anyone know what this means? Is there a problem that will reduce profits per hour/day/etc? Or, is this another change in reporting made by flypool?

I've noticed the same thing. I had to go through each rig to confirm that all cards were indeed running
