Posted 9 Nov 2023 by Mr P Hucker Post: Sorry for the off topic post, but I stayed at this campsite/B&B/kid's charity and would hate to see it closed down. Network Rail never paid them the £250K damage they caused by making a flood by blocking a stream. Now they're doing this.

Posted 1 Oct 2023 by Mr P Hucker Post: I don't understand people's aversion to necro posting. If a subject matter is still relevant, then the conversation never needs to end. For example, I had a question about a game which wasn't working right. I found someone else asking the same question 2 years ago. I finally fixed the problem myself, so I replied to the post with the solution. If anyone else has the same problem, they'll now find it on google.Threads in here keep getting closed, why the censorship?You can still read them, so no censorship. ;-) |

Posted 1 Aug 2023 by Mr P Hucker Post: I have 6 of these pc's and they each have dual Intel Xeon quad core cpu's that think they are 8 core cpu'sYou mean they're 4 cores / 8 threads? so 16 cpu cores in each pc AND I got them for $250US shipped to my door only needing a harddrive and a gpu to run.You don't need a GPU to run a computer. They all came with 16gb of ram as well which I have upgraded to the pc max of 32gb except 1 pc that has 2 bad memory slots in it so it only has 24gb of ram in it. They crunch everything I've thrown at it so far except LHC and LHCdev but that's probably something in the software, Linux or Windows, that's not been updated.LHC should be fine, I've got it running on an old 4 core with 6GB of DDR2 RAM! Theory is easiest to run, older CPUs crash CMS, and Atlas needs a lot of RAM. The only requirement is Virtualbox. And LHC will run with Virtualbox 5, 6, or 7. I use 5 because that works best with Cosmology. I have used an adapter in regular Dell pc's before to upgrade the psu and that has worked great, they make 24pin to 8 pin Dell mb connectors. The only thing is they have to stay in the original case because of the way the power on/off, the sound and the restart buttons are wired into the mb they use a plug not individual wires and I've never found an adapter for that and I'm not running a bump switch to start the pc.Why not just use a big normal tower case, and take the switches off the Dell case? Just fix them to the new case in some way, use one of the 3.5 or 5 1/4" bay covers to glue or screw them to. The older pc cases have very poor airflow and no top fans at all so modern day gpu's don't do well in them.I prefer to keep my GPUs outside the cases. Or leave the side off the case. |

Posted 1 Aug 2023 by Mr P Hucker Post: Those are really rubbish. Any decent supply has no such limitation. And in fact the PSUs I use for GPUs only have a 12V output! HP blade server supplies, £12 for 2.6kW at 97% efficiency, can't get much cheaper than that. If you want to use a supply you found in the local skip, simply place a load on 5V, a lightbulb for example, or something useful like some cooling fans. Actually, to require 5V current to make 12V work is utterly ridiculous. Why would one rail care what the other is doing? Must be some weird botched together circuit in there. A proper power supply generates 12V, then creates lower voltages from that. Even if the 5V was generated from scratch from the 240V, why would it affect the 12V part? I've got some of the cheapest PSUs available for powering the MB/CPUs. CIT supplies. Where it's pronounced with a soft C. They work, but 12V is rarely 12V. Somewhere between 11.3 and 11.9 (yes, even with 5V loaded). The MB/CPUs are happy enough on them, but old GPUs want more volts, I like to run them at the max 12.6V, keeps the tired ones awake. So those CIT supplies, they start up and run just fine with only a 12V load. I've got one running the window fans in the garage to stop the room overheating in summer, and one powering extra stuff - fans for the xeon CPUs where the weird Dell MB has non standard connectors, instead of bothering to hack into the 12V line from their own supplies, I just use this one, it also powers the SSDs as for some reason there's no molex or SSD power connectors on those supplies, maybe I'm missing a riser board, and a booster fan for the laptop which gets far too hot with the pitiful one inside it.When they're not powerful enough, you don't need a bigger compatible one, you just need more on the 12V line. Just get any old PSU and use it in addition.Works only with PSUs, that don't require significant load on 5V to keep the 12V line at the right voltage. Some won't even turn on without something @5V. But we're not using professional servers in cases. I for example simply place the GPUs flat on the shelf. If it was metal, all the solder joints on the back would be connected together. I can't fit 6 GPUS into the desktop case. They sit next to it.By the way metal shelving is a bad idea, you're asking for shorts. I use wood.I understand why you are worried about shorts, but in general, as computer cases are made of metal, there's nothing wrong about putting them on metal shelves. Server racks aren't made of wood either and nobody worries about shorts there eiter. |

Posted 1 Aug 2023 by Mr P Hucker Post: Because my pc's are on wire shelves like thisThat's a very low resolution image, but it looks like you could just shuffle them around a bit and put the PSUs next to them. The ones on the floor on the left you just sit the PSU on top. By the way metal shelving is a bad idea, you're asking for shorts. I use wood. |

Posted 1 Aug 2023 by Mr P Hucker Post: Probably you even can't use anything else than the original PSUs, the HP mainboard seems to have non-standard 18-pin connector according to the pictures I see on Google and Dell is known to use own wiring on standard ATX connectors, so you'll burn the mainboard and/or the PSU if you use anyhing else then the original PSU.Nonsense, you can find the pinout easily, especially if you have a working PSU of that type. Or just buy some 2nd hand PSUs for that model. I got Dell xeon server PSUs for £25. When they're not powerful enough, you don't need a bigger compatible one, you just need more on the 12V line. Just get any old PSU and use it in addition. You don't even need to wire them together, just give the GPUs 12V from the other supply. |

Posted 31 Jul 2023 by Mr P Hucker Post: I have an Nvidia Quadro K600 (981MB) gpu on it and it crunches Moo just fine. I can't put a more powerful gpu in it because the PSU is too small and it's one of those case length ones that HP and Dell used. They are WAAAY too expensive to replace and there's no room for an external psu. The pc also has 2 quad core Xeon cpu's in there as well, so 16 cpu cores.How can you not just sit a PSU on top of it for the GPU? I use a couple of very powerful 2.6kW power supplies for all the GPUs, and a couple of 1.3kW and a 1kW. They're connected in parallel and power all the computers' GPUs. The 2.6kW ones were £12 each! Old HP Blade server supplies. 200A each at 12V. Very long and thin. 2.5 foot long, a few inches tall and a few inches wide. |

Posted 26 Apr 2023 by Mr P Hucker Post: I believe processing numbers _2 and higher helps clear the backlog. It doesn't necessarily mean the validator is crashed it just means it's struggling to keep up with demand. In the past I believe this has been partly to do with the fact the ready to send queue has been so large. I believe admins had an idea how to fix it and it would appear that has workedYou have a point, once you clear off ones that match with others, there's less in the database for the poor server to work out. Just don't cancel the lower numbered ones or it has to resend them. |

Posted 26 Apr 2023 by Mr P Hucker Post: That is the `problem` of having a room full of parts ,I just bought two "for parts only" 1600W UPSs, with decent batteries in them (I tested them and they were 100%). The two together went for a lot less than one new one. And they work perfectly! Nothing wrong apart form a couple of dents! The seller clearly didn't have a clue, he said he couldn't get them to turn on! I'm putting both sets of batteries together and giving one to my parents so they get hours of TV in a powercut, and adding mine to my array of caravan batteries. |

Posted 25 Apr 2023 by Mr P Hucker Post: Doesn't that queue mean the validator is crashed, which means you won't make a difference doing that.Perhaps I could increase the cache next time I see waiting for validation piling up.When I see the validation queue starting to pile up this is when I will start contributing in clearing any _1 or higher numbers before processing any _0 tasks. I haven't seen a pileup in quite some time |

Posted 25 Apr 2023 by Mr P Hucker Post: I had a tiny old Nvidia for a while. I think it was one of these, but the PCI (not express) version: It refused to run any project except Seti, everything else was too complicated for it. It eventually stopped working through fatigue. I run everything around 70C. I set fans to run 0% at 50C to 100% at 70C, but they often go past that to 80C. Keeping it under 70 would be impossible without water cooling or a very cold room. I run them in the garage and there are tropical parrots in there, so I aim for 20C ambient, with limits of 15-25. I'm currently (stupidly) trying to rescue an old quad core machine. I replaced the motherboard when it refused to boot, which made it work but often at 1/15th speed. I thought it had bad voltage to the CPU, so I replaced the PSU which didn't help, then got another motherboard for it. That one refused to work at all because I'd managed to buy one which only took 4x1GB sticks, not the 4x2GB I had. So I bought more memory, and it still failed to start. So I bought a new CPU. When I get round to fitting that, I'll end up with enough stuff for probably two computers and some spare parts! Strangely the motherboards will sell on Ebay for the same price when they're broken. |

Posted 25 Apr 2023 by Mr P Hucker Post: Doesn't Milkyway have stuff available 99% of the time? Actually, Milkyway is best for the old AMDs or the pro cards, with a more sensible DP ratio than Nvidias. I run it on 12 Tahiti cards, 4000 GFlop SP, 1000 GFlop DP. I guess you're running out of things to do with it. I'm surprised such an old card is still going, does it run 24/7? |

Posted 25 Apr 2023 by Mr P Hucker Post: I don't care if the pharmaceutical company makes money, if it means people get cured, it's worth it. What GPU do you have? Most will run Folding@Home to cure cancer. I've even got an RX560 on it (only 2500 GFlops). If it's the GTX 275 I can see in your details, that would be too slow. But you could run it on Einstein or Milkyway. There's GPUGrid for biology, that only uses Nvidias, not sure how fast they have to be. |

Posted 30 Dec 2022 by Mr P Hucker Post: +1I've given away or sold anything that old, my slowest is 2GHz, and broken. The MB and SSD failed simultaneously. Strange that, I've never known one break the other. Mind you the MB was already flaky - slow ethernet, intermittent USB, sometimes no display output. I found a working MB for £10, then sold the broken one for £15(!). SSD just arrived yesterday. |
