    Dual CPU Xeon LGA1366 are not worth the money

    This is a bit misleading.
    Yes the Ryzen 2700 is faster in some tests at stock speeds. Against a single Xeon Cpu...

    A bone stock Dual X5690 system is no slouch.
    Just about 1500 in cinebench.
    The Ryzen 2700, about 1525 or so.
    Basically no difference.
    Ryzen 2700x about 1700...
    If you air cooled overclock a dual X5690 system, the Ryzen 2700x suddenly isn't faster, at anything.
    Water cool it, well, do the math on that....

    You can sometimes find used dual X5690 servers on ebay for less than the price of a Ryzen 2700x cpu.
    How is that not a value if a complete server, is cheaper than a 2700x cpu?

    Only dual Xeon X58 board which has offered any kind of OC on Xeon has been EVGA SR-2 which I owned for few years until failed and took both CPU and all RAM

    They're been few others from Asus but with them OC is bit limited

    If I built any dual Xeon or workstations usually I use Supermicro or ASRock boards as with them have bit better luck bit still with X99 or X299 you are not limited by so much if you are building GPU based workstations than CPU

    Hope this helps

    Thanks, Jura



  • There's some discussion on water and air cooling. which is better? I generally don't overclock. I'm following this thread closely because I think my computer is already on borrowed time.

    @ghostship They don't need a controlling workstation; any of my servers can run on their own, including displaying a desktop on a monitor (they have an onboard video chip). I use a KVM box to switch a single keyboard, video monitor, and mouse from one server to another. Each server has a unique desktop background picture -relevant to their unique name- so that I know which server I'm seeing. My blade servers lack a sound card, but have a PCIe slot if you'd want to add one. Clio (Dell r610) came with an aethernet card in that slot, so she has a total of seven aethernet ports! 0_1549770802732_boggled.gif

    Those "enterprise refurb" resellers also sell workstations (like my T7500 TinkerBell) with dual processors; I see that option as very good "bang for your buck" to get a lot of rendering power (lots of CPU cores and plenty of RAM) on a modest budget.
    Urania is an HP z600 midtower workstation; the full tower was the z800.

    I'd love to have a new workstation, but they're too expensive. I can afford the used ones; they cost a fraction of their new price.
    Clio (dual X5690 Xeons) cost about $25,000 new; I paid $340 for her.

    If you don't OC and prefer quiet system then air cooling is way to go

    But this again depends, do proper water cooling loop can be expensive but with right parts can be not so much

    If you mean by watet cooling, cooling with AIO or CLC kit from Corsair, Thermaltake, NZXT don't bother with this, its noisy and is not worth it if you are comparing with good air cooler like is NH-D15S or NH-D15, Thermalright Le Grand Macho RT plus BeQuiet Dark Rock etc because these air coolers are quieter and are you not risking failure of Asetek pump

    And again I would add, good case is worthwhile upgrade with good fans, if once case have poor airflow then you can have most expensive water loop or air cooler and still temperatures will not improve

    Hope this helps

    Thanks, Jura

    @redphantom Air (fin & fan) coolers will do for most cases; water cooling is a nice luxury for stock clock speeds. If I were overclocking, I'd probably use water cooling.

    Same model of motherboard, one -Cameron- using air (fin & fan) cooling...

    ...and one -Galadriel- using liquid cooling:

    @ghostship said in PC spec priorities for Poser:

    @shvrdavid don't those servers need a second computer for admin because they don't have a video card? Just curious.

    My blade servers (C1100 & r610) all have PCIe slot into which you could install a single-slot GPU. My blades are all 1U high; if you wanted to use a double-slot GPU, you'd need a 2U thick blade chassis. Those are commonly available. I don't know if they would have the needed power supply cables.
    I do fine with the blades' onboard video chip; I think they displaying at 1280x1024 pixels, which is sufficient for a render slave unit.

    The workstation Cameron came with a subvariant of the SuperMicro X8D motherboard, the X8DAi-BT004, which sacrifices one PCIe slot at the bottom and replaces it with a SIMLC slot. The SIMLC slot is intended for a KVM-over-LAN card (aka remote management card) which enables you to use the workstation as a KVM switchbox.
    You can display sixteen server desktops in a 4x4 grid, for example. Select one of those servers, and its desktop will expand to full screen, and your keyboard and mouse now control that server. After using DLM to update Queue Manager on that server, you can then close the KVM display and go back to working on the workstation itself.
    SIMLC slot (always at the bottom):

    It would all depend on what server you bought. Most have some sort of video onboard.

    Many rack servers can use PCIe riser cards to add 4 to 6 graphics cards as well. Some can use a remote mount box as well. Similar to eGPU basically.



  • (Herb's Custom Computer

    At home, prior to joining the Poser team, I built my own custom wooden case with maximum airflow (quiet 200mm fans) .. sure it's not space efficient but it does the job amazingly well without needing expensive watercooling. (I do use a close circuit waterblock.) Lol sorry for the mess! The back side uses an eco-friendly cleanable furnace filter to catch the dust and can be removed to service most components. The top flips up for alternative access, but of course I've put my soldering bench on top so I don't open it too often. I did have to rebuild from mobo up recently because of an experiment with an older Soundblaster card causing some bios issues. The most expensive single feature of this build was installing 12 USB 3.x connectors in the side and running the shortest possible extenders. I used the "keystone jacks", which are for routing multiple cable types (HDMI, USB) in a house wall. The 12-jack socket wasn't expensive at all but the individual USB jacks that snap in place weren't cheap. I run dual GTX 750s (will upgrade some day) and 7 monitors.



  • I have found that the cheapest way to get usb sockets is to get the ones that go into an expansion slot.

    Like this.

    You can usually find them for about 5 bucks a pop


  • Poser Ambassadors

    Most of my stuff is too old to have originally come with USB 3.
    The motherboards generally have a few of the old PCI slots as well as some PCIe slots.
    I make use of the old PCI slots by installing a USB 3 host PCI card. PCIe cards with USB 3 are very common; PCI cards are not.

    In the SIMLC photo in my earlier post, the white slot is the old PCI type.



  • @shvrdavid Re: "5 bucks a pop"
    I have plenty of those and in fact one is in my system -- but it's not USB 2.0
    This is not the solution that would have fixed the issue I was referring to, however. I installed Keystone Jacks and 1-and-1.5m anti-dust rugged USB 3.1 cables to extend the 12 USB outputs of my computer's "front and back" panels to the side of the table, near the top, just under the table-top. I also used a card similar to the one mentioned by @seachnasaigh however I decided not to buy the $100 multi-port 10GB/s-gauranteed USB 3.1 (gaurantees maximum possible bandwidth for 8 ports but is 3x the cost because it has multiple controllers bundled on a single PCIe board) and got something cheaper that supports 10GB/s but has less ports.
