I don't know where you got your chart but it is wrong. Wrong context. That is for power transmission. As in utility company transmission lines. Also since they are talking about frequency and skin loss, they are talking about RF transmission not 60Hz AC branch circuit used for wiring a house or rooms in a building.

I use hospital grade or at least industrial grade outlets only. The plug clamping force on them is amazingly better than your spec home crap outlets that you find in most houses Absolutely, Hospital grade outlets. The higher the contact force, the lower the resistance and the less voltage drop and less heating. The material used in hospital grade are better in every way from the metal contacts, the screw connections down to the plastics used. The leakage current allowed for hospital grade outlets are magnitude in difference. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Where do "hospital grade" outlets get sold? Not at my local chain hardware store, I don't think. Or else it never occurred for me to look. Tom A proud member of the OFA (Old Farts Association). |

You need to find a "proper" electrical wholesaler, preferably one local to yourself rather an an internet source. They will be able to source industrial and hospital grade outlets. Be warned - they won't be cheap. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Be warned - they won't be cheap. Sigh. It is possible that it is a fools errand for me. I live in a mobile home. I do know that my light switches, the ones I use the most, started quitting a couple of 4 years ago. So it wouldn't surprise me that my outlets are at best mediocre. The only thing I am sure of is my Master Bedroom/Kitchen 110 volt is on a different circuit (GFI grounded?) than the Living room and 2nd/3rd bedrooms.

Either as Rob said, a wholesaler near you, or as I have done for years, off of Ebay. I pay close attention as to who is selling it, and only buy major brands, Hubbell comes to mind as well as P&S. Just did a quick check, came across these, they seem to be a decent deal, though it appears he might not combine shipping, so if not only an average one compared to all the others listed on there. Might have to pick up a few for myself if he will though, as he's sold a bunch of them so far, and still has 100% positive feedback, and as of this post it appears he has about 25 left. I've also installed a couple of these as well, they are actually quite cool, though not exactly inexpensive. Here's the same thing just in a 15a version. Just do a search on there for hospital grade receptacles, a bunch of them come up. I seem to usually buy the orange ones, or red ones, but then, they are most often going into work spaces, not my living room so that works out fine for me. |

Ok, so I have been shopping for pieces to try for an upgrade of my Mid-Tower case. This means it has to be an ATX mb, apparently not an Extended ATX mb. I was told I am looking for a "mainstream X399" mb. Is this acceptable and sufficient? https://www.newegg.com/Product/Product.aspx?Item=9SIADFR7W11500&ignorebbr=1 I am trying to be both price sensitive and buy a solid quality MB. I don't need flashy lights or fancy color schemes if they raise the price. Is there a better value out there for the kind of processing with the Threadripper 2 I am planning to get? Thank you.

Tom, you might want to consider using these, my guess is that you will probably have shuffled off this mortal coil before you had a chance to wear them out... ;-) Just a quick word of advice to you about GFI circuits and appliances. Back in a prior life, I did appliance repair on mid to very high end brands, and one thing that I was told at the time by most mfgs was that you do not want your major ones (dishwasher, microwave, fridge, washer/gas dryer) on a GFI outlet/circuit. It was found to sometimes cause weird issues with the electronics. The downside is that to be code compliant, you might need to install a single dedicated receptacle so nothing else could be plugged into that 'dangerous' outlet. I dunno, honestly none of my outlets in my house other I believe than what had to be outside (due to my solar system install a few years back, to pass inspection) in the garage where everything comes together. And the funny thing is, I haven't died yet. Strange how that works out. |

Don't know about you, but I would be afraid, very afraid. :-O If building a new system, the last thing I would want to do was to have to try to chase down someone elses' random weird issues. My guess is once it came back in after the return, it went thru some normal/simple testing, and couldn't find anything wrong with it, so hence it ended up for sale again here. Possibly the person before was a gamer, or someone like us, who really puts it thru its paces and stresses it more than the average youtube/email computer user, and that might be where the issue shows up, which probably would not appear during normal low stress testing. I'll see if I can do a little searching later today, and see if there is yet a consensus to be found on which is the top teir of TR2 boards, in both price and performance, because like you, I couldn't give one rip about eye candy, I just want it to work, solid performance, thank you very much. I'll post what I come across here, hopefully with some helpful links. |

Well, for giggles, I Googled best X399 motherboard, looked at the first site that popped up that rated them, then searched on their top 3-5 recommendations. On Neweggs site, one reviewer in a comment while giving a 3 star review said that that one was the best X399 board out there so far, and after looking at the reviews of a few others, I found it to be somewhat depressing actually. I know that more ppl will write in with complaints than with positive experiences, but it appears that the major brand (regardless of price, as some of them retailed for about $450), boards all seem to be lacking when it comes to the TR. Not sure why, maybe that it's a newish chip, maybe they saw that it was going to be popular and rushed them out, I have no idea, but the few that I'd looked at quick (so far at least), well none of them really stood out as Buy Me!, regardless of the price. I'll keep digging a little later though, and see what I come across and will let you know of anything positive I can direct you towards so you can research it some more. Interesting little blurb I found on TR2 speeds on Linux vs. W10. Didn't read it all the way thru yet, but looks to be a positive thing for Linux fans if the software can take advantage of NUMA. *edit* Hmm, you might want to take a closer look at this one: ASRock Fatal1ty X399 Professional Gaming, it has 46 reviews, at 4 stars, which is the best I have seen of any that have anywhere near that many reviews, and it's a $449 MSRP board that is now 359.99 after $30.00 rebate. Take a look at it, and the reviews, might be something to consider? Just tossing it out there. Oh, and the first downside I see to it is that they are limiting purchases to only 20 per customer.. Bummer! lol And I presume you can turn off all those loverly RGB lights all over it, right? |

That's a great buy on the 20A Hospital grade outlets. Normal price is $20 a piece for a duplex outlet. The way you can tell a Hospital grade outlet from a common one is the green dot on the face. The outlet is made from nylon and not cheap plastic. The "best X399" site has the order fairly well developed. The ASUS ZE on the top matches how I would order it with the MSI on the bottom. I too would avoid any refurbed board. No way of telling if any returned board went through a proper manufacturer recertification. The BIOS is best on ASUS, then ASROCK, then Gigabyte and last MSI. That goes for 1st gen boards. Only 2nd gen board so far is the MSI X399 MEG Creation which is top board now because it has the VRM and heat sinks for the 2990WX. Also pay attention to slot spacing if you intend to run four double wide gpus. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

If you want to study up on all the X399 motherboard offerings, a excellent resource is the OCN X399 forums that cover all the X399 boards released so far. AMD Motherboards Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Keith, after thinking on it for a little while, my gut is kind of telling me that maybe it might be just a titch early for getting a solid TR2 board, especially after checking thru a number of reviews of them? Nothing solid saying they are junk or anything, it just seems that maybe things are still a little under baked at this time, and if a person were to hold off maybe till early next year, say mid 1st quarter or so, the selection might expand a bit by then, and things might be a little more settled in the features and quality dept? I know you can always wait and wait, and never pull the trigger hoping for the next release to be perfection, but it just seems to me that things aren't quite 'settled' with the X399 situation yet? Thoughts? I of course could be completely off base on this, I have 0 practical experience with AMD procs. |

Oh, and just got a message back from the seller of the reasonably priced receptacles, he will combine shipping on them my order would be $15 in a med flat rate box, so if you're serious about ordering some, you might want to get it in tonite or right away tomorrow morning, as he said he's leaving town thurs and won't be able to ship them till next week otherwise. |

No the TR2 processors are solid. All the benefits of the Ryzen+ advancements. The only questionable products are the new 24 and 32 cores cpus. I would order a 2950 without any concerns. All the benefits of lower latencies, better memory scaling and autoboost that Ryzen+ brought into being. All the 1st generation boards can handle the 16/12 /8 core processors without any concern. Only the new 24/32 core processors exceed the design limits of the 1st gen boards. Only the new MSI MEG Creation board is capable of running those so far. I think that once again AMD has given the board partners little or no advance knowledge that those cpus were imminent. It seems AMD is repeating the same mistake they made on Ryzen launch with processors on the marketplace and nothing to put them into. I don't know who is running the AMD interface teams with the board partners but they have dropped the ball again. I wonder if it was a decision to just launch and steal Intel's thunder first and worry about the boards later. So, yes I would definitely wait out at least half a year for more TR2 boards to make it to market for the 2970WX and 2990WX chips. I would want more choices than just MSI.

So what I think I am hearing the two of you say is I need to put off this particular upgrade until next year? These two claim to be version 2 ready. https://www.newegg.com/Product/Product.aspx?Item=N82E16813144079 https://www.newegg.com/Product/Product.aspx?Item=N82E16813157785 Both are within price reach. At least one of them has really wide video slots. I can imagine going to a 3 card arrangement. After that, I presume I would need to go to the out of slot solutions. So I need to wait and hold my breath, till I turn NewYears blue? :) Tom A proud member of the OFA (Old Farts Association). |

The MSI Board DOES NOT have CrossFire NOR SLI, (good for BOINC), while the ASRock Board HAS BOTH!!! So, IF you go with the ASRock Board, you'll have to see if CrossFire and SLI can be Disabled in BIOS. TL TimeLord04 Have TARDIS, will travel... Come along K-9! Join Calm Chaos |

SLI is not required by SETI, but may be supported by other projects. SLI can normally be disabled in the BIOS, but more often than not the nVidia GPUs need the addition of a cable between them for SLI to work. In the case of the ASRock board it is described as "supporting 4-way SLI" - this does not mean that you automatically get SLI. If ASRock use a similar BIOS to Asus then you get a prompt when you first load a second (identical) GPU asking if you want SLI or not, and once you say "no" the prompt goes away and you don't get it again until you put the jumper between the GPUs, or put another GPU in. No need to dig in the BIOS for that, but one may want to go in for other reasons..... Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

I would point anyone considering the 24/32C TR2 cpu to go read my earlier post in the thread. Message 1955118 and go view the link I posted by buildzoid. He explains the current requirements of the 24/32C cpus and why only one current board is capable of running them properly and at full capabilities. The only current board that can do justice to the 24/32C cpus is the MSI MEG Creation X399 board.
