...Meanwhile ASUS released a new BIOS a couple months ago aimed at stability, seems to work well.So far all is well running the two 'extra' cards in the bottom group, connected to a Third Power Supply. I've never had enough cards, or a reason to run cards in the bottom group before as it meant running a Third PS. So, I left the one slot open in the middle group and just added two cards to the bottom group, I never tried this arrangement before, and never tried additional cards with the New BIOS either. Going back to the 'Stock' boinc with just 2.8k tasks caused a large number of tasks to go pending, it appears the pending number is leveling off now, so, the RAC should start rising again. I kinda like running the non-spoofed client with just the driver hack, it's something different ;-) |

the spoofed client only works with the number of GPUs it was built for. if you need a 14-GPU client, just ask Juan to build you one. The spoofed client is only necessary if the Seti maintenance cycle turns into an "all day event". Since (so far, FINGERS CROSSED) we are having real live 5 hours or fewer outages, the spoofing is less necessary. Tom A proud member of the OFA (Old Farts Association). |

Still running fine with 14 GPUs. I think the CPU is showing some strain though. I've ordered a stronger CPU cooler for the 6700K and will swap out the 6700 for the 6700K when the cooler arrives. Right now none of my cheap coolers will cool the 6700K at over 60% usage, even at 60% you have to turn off the boost. So, later this week the new cooler should arrive. I might even try 15 GPUs after then. |

Not only would that ruin production but it might make a rather large hole in your pocket :( Go get them...... "more gpus" :) Tom A proud member of the OFA (Old Farts Association). |

since you aren't using the CPU for anything other than feeding the GPUs, you can also try underclocking the CPU. set the core ratios to something low like 30 (3.0GHz), it will reduce power use and temps. I did this on my 7700k when it was near maxed out with 7 GPUs (w/ nobs), and an inferior cooler, though i didn't try clocking it down quite that far. just a 200MHz underclock from 4.2 GHz to 4.0GHz.

Hi Tom, CPUs will not fry. I have seen CPUs running with no cooling solution at all and with extreme loading and they keep on going. They are protected from "frying". I have not seen any go over 100C. They throttle back. As long as you keep the CPU 70C or below, it will not throttle. My i7 8086K is running high 60s to low 70s with AiO cooling.

...So, later this week the new cooler should arrive....As per course, the order got delayed and won't arrive until Tuesday. I decided what the heck, I'll try it with the last cooler I bought which didn't quite cut it in the Hackintosh. To my surprise the Cooler Master i70C works much better in the Mining machine, in fact, with the 6700K CPU at Full power the temps are in the mid-70s. Not great, but it will work. It seems there is about a 10-15C difference between the cases. It should be even better with the New cooler, but for now it's running at Full power without any trouble. The run-times have improved quite a bit, it would appear the Mining machine is hitting on all 14 cylinders for now. |

Its good to hear that you will have a reliable backup after the new cooler cooler gets here. Its great that the experiment appears to be showing itself to fully reliable. Now if we could manage the 19 gpus ;) That would get more than a little complicated because the setup under mining was supposed to be 50% Nvidia and 50% Amd gpus. And I just got done with an attempt to combine both on a much smaller scale and promptly ended up with the Open CL portion of the two drivers fighting with each other. I am ignoring the customized "app_info.xml" that you would have to put together. In any case.

CPUs will not fry. But they do just quit working for no apparent reason. I just have had two i7-6850K cpus go bad in the past two weeks. Temps were never higher than 60° C. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

CPUs will not fry. Hi Keith, I'm not saying that a CPU cannot go bad. I'm just saying that the CPUs are protected from frying. There may be something else causing the i7s to go bad, but if they were no higher than 60 C I doubt that was the cause. They will go to 100 C before starting to throttle. Then again, you could have gotten a couple defective CPUs that could not handle the heat, who knows. A CPU that is not defective will not fry from heat. I have seen it. No cooling solution and they did not quit working. My i7 8086K runs high 60s low 70s. From what I hear that is optimal. Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS?

This worked out nicely for me. My open frame systems have their PS2 connector blocked. One mombo, x8dtl, with dual Xeon x5675, does not enable the USB port during the start of the post and it was not possible to get into the bios to make speed changes w/o disassembly. The processors, x5675, do not support Thermal Monitoring and were running too hot even after removing the protective film from the water block (another story). TThrottle help but the temps were erratic and on border line. I got into the windows power plan and set the %processor usage to keep the multiplier at 20 which made a huge difference in temps. GRC mining pays CPU or GPU projects equally so I always mine on CPU projects. I would not know how to do this on my Ubuntu miner but it does not have a heating problem and its USB ports work during post. |

Fortunately both of my MB's boot with USB active when the bios is up. That is the only downside besides it not being as "pretty" as a regular case.

Make sure the kb is plugged into a USB 2.0 port. Not a 3.0 one. Should work in the bios that way. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

CPUs will not fry. Who knows, the first one lasted 14 months with an overclock. Its RMA replacement at a lesser overclock lasted a week. I chalk up the RMA failure to infant mortality, some major manufacturing flaw in the cpu. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

CPUs will not fry. In all my OCing adventures, I have never cooked a CPU. Froze one once....LOL. It was always the mobo that gave out under stress. Meow. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

CPUs will not fry. The motherboard continues to soldier on with either of my two backup Xeon processors running perfectly fine. Intel told me to go screw myself even with the insurance I purchased for their Intel Performance Tuning Plan. That was $35 thrown away. I won't be replacing the i7-6850K since they seem to be fragile or something. At least not at the $650 price at Amazon or Newegg.com. The Xeon E5-1660 V4 ES chip I bought off eBay for $230 is beating the old 6850K with its more cores and lesser clocks.

CPUs will not fry. That is a bummer. I have some Haswells that keep rocking away with moderate OCs. I push them hard on PrimeGrid with the LLR apps. |
