I've decided to build myself a newer more up to date computer than the old dinosaurs I have been running. So here are the parts: Motherboard: Asus Z10PA-D8, (in my possession) CPU(2): Xeon E5-2620v4 (in transit) CPU Coolers: Noctua NH-D9L Case: Fractal Design Define XL R2 Power supply: EVGA 220-PS-1000-V1 Memory(8): Kingston ValueRAM KVR21E15S8/4HA HD: Boot drive: Samsung 850 EVO - 120GB - M.2 SATA III Internal SSD (MZ-N5E120BW) Data drive: Samsung 850 EVO - 250GB - 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM) GPU(2): ASUS GeForce GTX 1080 8GB ROG STRIX OC I haven't decided if I will be using Linux Mint or W10 as an OS, probably or most likely W10 This will take me maybe 1 to 2 months of ordering parts because that is how long it will take me to earn the money, but I got a good start. Made a mistake in ordering parts for my new build. I also have in transit, (2) Xeon E5-2670's, unfortunately they are incompatible with the motherboard I just got. But they will not go unused. I will get 2 more motherboards that will support them and replace the boards in PC-Office and anise The board I have in mind is: ASUS Z9PA-U8 |

congrats , big fat cpus , what next on this board ? oops also congarts on the forgotten gpus, well fat done. Are you aware of flashing the mainboard bios ? |

Congratz on the new rig. I wasn't familiar with that particular board, so I did a little looking around on the web, read a few reviews on the egg and Amazon, it seems that it may, at least at the the time they were written, have had some issues with the W10 drivers, so that may effect your OS decision. One guy had horrible issues with DPC latency, but for normal crunching, that should have no impact. It will be interesting to see how well it performs when you get it all thrown together and have those 32 cores crunching. |

32 cores , and 64 threads, this cpus got HyperThreading |

and remember, Quad-memory channels for both of these CPU types, so always buy RAM in 4's, and install 4 at once. |

oops , i need glasses XD Struct down by Intels webside. Have read the wrong line. |

Yep, per Intel, the Xeon® Processor E5-2620 v4 (20M Cache, 2.10 GHz) is 8 core, 16 HT x 2 for 32 cores total on that build. |

These CPUs runs so fast, if you try to use triple channel or 2 channel, your memory control will bottleneck. The V3/V4 are DDR4, but again - quad channel. |

That is actually different advice than I recieved from Supermicro on my 48 core dual Xeon build. For that system, it said that the highest memory peformance (1833) would only be attained by having only one DIMM per channel, so a total of 8 sticks of RAM for the entire system. Having more than that slows the memory down, to 1600 or below. It has 32 gig in it, which is way more than enough, but the price was right for it, and it was Hynix, good stuff. This is a link to the manuals for this board, I don't have an Acrobat reader installed on this system, trying to keep it as clean as possible, but I'm sure it talks about different memory configurations in one of those links on that page. Here is a link to the QVL list for memory as well. |

Wouldn't that advise only be helpful if the speed of the RAM was more important to the applications running on it than losing the 256bit (64bit x4) memory access of a quad-channel configuration, and not needing much memory than originally spec'd? In general, for server workloads, having fatter access to memory always outperforms a few extra megahertz of speed. |

Possibly, hadn't considered the channel bit size, mine is tri channel on my V2 proc and board, so potentially 192 bit, but at potentially a 20-30% decrease in memory speed. Tradeoffs it seems, faster over a narrower bus, or slower over a wider one. Depends on the application, and as I don't know nearly enough about how BOINC works to know where the break-even point would be, I'll leave that to much better informed individuals than myself. :-) And learn something in the process! |

Here are my current computers When I get the motherboards for the E5-2670 cpu's I just got, I'm going to have to swap the boards between PC-Office and Jolinar, because the new boards will be ATX and the old eMachines case is mATX, and the motherboard in Jolinar is mATX. The box fan on top pulls the heated air away and I have 2 9" vans pointing up from below. Instead of getting case and psu I ordered the motherboards for the E5-2670 cpu's I got. I ordered 2 ASUS Z9PA-U8 ATX Server Motherboard LGA 2011. Best price I found was $283.99 USD. And I ordered 2 sets of DDR3 Quad Channel memory too. Memory showed up yesterday (2016/07/13) and I got the motherboards today (2016/07/14). Got one installed. Went for the easiest install, no case swap. Computer anise 5541574 |

You got a wonderful setup. I need to get myself a rack like yours. Currently I am using a plastic one. |
