Phew  Thank you for your help Philip, sorry for a small hijack of your thread. Went to buy 2x 1080Ti and couldn't pay so that have triggered my question. ZOTAC or EVGA ? Thank you again for help Never used zotac, but as reported, Phil has seen good results. He's also right about EVGA, I specifically only buy their cards now.... Quality product; over-engineered (not in a bad way in the slightest); and the warranty is second-to-none. I highly recommend EVGA products. I agree. My farm is mostly FE edition and after getting 2x evga 1080ti sc2, I'm never cheaping out to go with FE again. A lot quieter, 100mhz higher boost clocks at same power draw, 3 - 5% higher hash rate that my batch of FE cards and best in industry warranty. Even if it costs $30 more, I think we can recoup part of that $30 when reselling. Have you checked if zotac gives 3 year transferrable warranty too? See if i was to start over and buy ALL of the same card, it would be the Asus Turbo 1080ti's, out of all the 1080ti's they are the only cards that have given me 0 issues to date on multiple rigs as well seem to cool the best during the peak of the day here in Florida with the 95+F temps.... They do run hotter naturally it seems, but the fans on them are just amazing at the higher fan speeds it seems, so at night when the temps are the coolest, they are running at the highest fan speed to maintain my 70c target temp, but during the day around 3pm-ish, they run of the lowest fan % to maintain the 70c target temp and the hashrates on them are kinda in the middle after applying overclocking, they dont hash as well as the EVGA cards, but they beat the pants off my MSI and Gigabyte cards in hashrates, especially during the hotter parts of the day.. |

The best and most stable GTx 1080 Ti that we have is actually the EVGA FE model that I have as one of the two in my personal gaming rig (other 1080 Ti in there is a Gigabyte). That EVGA FE runs with the highest OC of any that we have and has not had a single hiccup in all the months I've had it. It stays pretty cool too considering the cooler and being a SLI setup inside a traditional case. I think we have 12 or 13 1080 Ti in total and that EVGA FE will run +250 core all day long while none of the others can even stay stable at +200 (that's at 80% power limit).

Phil.... with BIP91 now in effect.... the latest Core wallet has this message on top "Warning: Unknown block versions being mined! It's possible unknown rules are in effect"... is that normal? Thanks

Take a look at the top of the forum page: News: The warning which may be displayed by Bitcoin Core about unknown versions is related to BIP91, and can be safely ignored. |

You should have kept one single thread, it would have been the biggest altcoin mining thread I guess ! Anyway I will be following this one.

I find it EXTREMELY ironic that the _newest_ wallet says "unknown rules".
My only comment on that one....

Just wanted to chime in on the 1080 ti discussion I have 5 of them running in a closed 4U rosewill case and they are cruising along at @ 85% power, +200 core, +500 memory They are all Founders Editions as I needed blower cards, and the highest temperature I see is on an EVGA ~64 degrees, but I think it must be in the worst spot for airflow. I haven't been chasing efficiency at all, and just went for a good solid overclock that was stable 24/7 with EWBF. Next rig is going to be 6 or 7 1080 ti's in a closed 4U case, but I'm not sure even a 1600W PSU will handle 7 cards, so it might just be 6    |

Are you running the airflow in the case backwards? i ask this because i was planning on putting rigs into 4U cases and bought 2 cases, i put 5 cards in one and because the heat was being circulated over the CPU, i was having issues with the CPU overheating on me... so that build has been running with the lid on the case off since then with a box ran layed on top sucking the air out of the case...
I myself run them backwards as seen in the photos.... It's easier for cable/riser routing for the most part. I can see how it would be annoying for normal data center mounting as airflow would be backwards and be an issue of sorts. If you replace the two fans seen at the back of the case with higher flow ones; you shouldn't have any issue with cooling the CPU; but; running them backwards as the photo shows; keeps fresh air going over the CPU. I wonder why your cpu overheats.... The cpu itself shouldn't be doing much hard work at all.... What processor/cpu cooler are you running? [in the past] I've had home PC's that have an internal case temp of 80C, and the processors never really hit much over 90c..... |

Mine are in a DC so I need front to back airflow, as the racks are setup with hot and cold aisles. The airflow is coming through the front and all of the cards are blowing out towards the motherboard/cpu/psu. There is a row of 3 x 120mm, 3000rpm Skythe fans also blowing towards the back and then 2 x 80mm fans that came with the case. The CPU is cooled by a Cooler Master Hyper D92, and it runs @ 30-36 degrees, and I've never had an issue with overheating at all |

I tested EXP, ETC, and ETH. The two with large DAG files hash slower. EXP's DAG is much smaller and mines at full speed. This was all tested on Windows + Claymore. Other setups don't suffer from this . |

Other setups don't suffer from this . The articles were overstating the hash drop from the Claymore epoch benchmarks. In my own testing the the actual drop was less than 0.1 MH/s per card for every new epoch, nowhere near the '30% incoming' they were stating. They also made no mention the ETH block times are getting longer from the programmed ICE AGE, so even if nothing was done to correct the issue, it would take more than 9 months to reach the benchmark stated 25% hash drop at epoch 160. |

The airflow is coming through the front and all of the cards are blowing out towards the motherboard/cpu/psu.
Shift all the cards "up" (as shown in the picture) an inch or so should help if the bottom card is the one that is overheating. Also, there ARE non-FE blower cards around, most of which clock higher by factory default vs. the FE - ASUS and Gigabyte in particular, and they're not much more than the FE models while having better cooling solutions than the FE does. |

I'm thinking it might actually be the top one as the fan there blows right at the PSU. I need to find some to test at some stage |
