  1. I see the new benchmark - The Simon's Challenge. Is it hard to reproduce? I would love to test performance of my machines with it ;)
  2. 1. It works on a wide range of devices - from multi-cpu (i mean WAY more than 2 multicore processors) servers occupying the entire rack to the small Raspberry - and it uses the same set of development tools and the same interface, so you don't have to relearn. 2. It's FREE. You can't compete on the price/performance with something whose price is literally 0. You just can't. 3. Device support. Yes, long time ago it WAS a big issue, i remember myself backporting the Adaptec SCSI controller driver from DOS to Linux kernel 0.99 (yes, i'm that old and yes - i work with Linux for that much
  3. LTT became lazy preparing slides with technical information. IP that looks like 123.456.789.0 ? We laughed at it when movie "Hackers" came out. I was not expected that kind of f-ups from LTT. Come on guys?
  4. It's Micro-ATX, not Mini-ITX. Also cool, but not that impressive.
  5. To hell with Threadripper. Epyc Rome FTW! 64 cores/128 threads Mini-ITX computer is what i really need. In DAN CaseS A4-SFX. With custom water cooling. Most epic sff pc ever!
  6. I doubt that ASRock Rack will produce a gaming motherboard - that's main ASRock kitchen, maximum - they will produce workstation motherboards - and they already did, on both LGA3647 and TR4 platforms, with sound, many PCIe slots, multiple m.2 and such. But they are kind of boring (well, not exactly, i'm using ATX sized ASRockRack EPC621D8A as my open test bench where i play with all the hardware) but there is nothing special about them - everybody do it: Tyan, Supermicro - everybody. OTOH MiniITX boards for Xeon CPUs are rare beasts.
  7. There is no much sense in it. It would have to be configured in 4-channel mode anyways, the reason for 6 dimm slots is to utilize the 6-channel memory controller of Xeon Scalable series to get the maximum memory bandwidth. With 5 dimms it kind of defies the purpose.
  8. 2 more SO-DIMMS. Actually there is another board from ASRock with 6 memory slots and no M.2 slots - epc621d6i. Unfortunately there is no space due to the clearance with the motherboard tray to put both 2 dimms and m.2 slots on the back of it (or 4 dimms for that matter). Here you can see how bottom SO-DIMMS are wired:
  9. I already built similar machine using the previous generation of Xeon processor (E5-2699 v4) and ASrockRack motherboard (EPC612D4I). I built it in the CoolerMaster Elite 130 case using 120mm AIO cooler - and it works 24/7 for last year and a half as a test server for my cloud applications serving like 20 to 25 docker instances any given moment. All of that is while it takes virtually no space on my table and being so quiet that i do not notice it. So, yes, there are use cases for such boards.
  10. Absolutely! Unfortunately i have another use for all of my Platinum equipped systems, but these two guys (i have no idea who they are but they look confident enough for me) apparently did this. They did it with Xeon W-3175X, but it does not matter - it is the same process. So, yeah, C621 chipset is working just fine.
  11. Stepping into Linuses shoes (well, sandals) and installing Hackintosh on my old machines: Xeon E5-2699 v4, not overclocked, in absence of CPU-Z screenshot is with the Intel CPUId tool for Mac OS. Mandatory picture of the finished system:
  12. All you need is go to BIOS, disable "Enforce POR" feature and then you will be able to just select the speed from any supported by the memory controller in CPU.
  13. If you take a look at his CPU-Z screenshot, it is the same 2.6 version that you got. 2.7 available on the retail chips only - all the QS and ES chips are slightly downclocked so you are fine. 8280M is more expensive only because of better memory controller - it allows to address twice as much memory as regular 8280 but i doubt we are going to encounter that limitation any time soon
  14. It's amazing deal - i would take it any day of the week. And your CB score shows it. As for the memory - it is just a 2400 memory overclocked to the 2933, any 2133 module overclocks to 2666 and 2400 or higher to 2933 - at least i tried more than 100 modules and never had any problem with that. If you read documentation to the memory chips on your DRAM module on the manufacturer's site you'll find that 2133 chips have timings when they clocked on 2133, 2400 and 2666 frequencies, so it is not even a real overclock - it is just overriding the data from POR registers on DIMM.
