Hello all,
I am looking to get some advice on a new build for our sfd station. I do not personally use the software but I will be the one recommending what we buy and the one setting it up. I am comfortable with normal desktop computers but this will be my first venture into the server side of things. i am hoping i have not overlooked something or given to much attention to the wrong area and neglected the areas i really needed. i have to recommend a budget to work with as well so i am trying to balance cost over performance. i am looking for this cpu to last 5 years. i am about $4700 so far: Windows 7 x64 (2) Xeon E5-2650 8 core cpu's 128GB DDR3 1600 ram, non ecc regular gamer quality supermicro MBD-X9DRH-IF-O Mobo AMD Firepro v4900 videocard (2) OCZ Vertex 4 VTX4-25SAT3-512G, 512GB SSD in Raid 1 (2) Dynatron R13 70mm 2 ball bearing CPU cooler (narrow type) asus generic dvd drive antec three hundred case corsair tx650 power supply MS office 2010 home and business some of the questions i have is do i have too much ram? or do i need to use the more expensive ecc ram? i am assuming i can fit all of this into a standard ATX mid tower, am i correct? is there a better CPU combo? i am building this to use autodesk's 2013 CFD and we currently use fluent, but i am unsure of the version. we do mostly hot oil modeling. is there anything i am missing? thanks in advance for the help. |

You must use windows professional or better to use more than 16GB of RAM, But I'm sure you knew that already.
What type of parallel licenses do you have (how many cores will you actually be able to run) I'd hate to get a 16 core computer and find out I only have enough licenses to run 1 core, or even 8, and I could have gotten 2 higher frequency quad cores for cheaper. 16 licenses for fluent would be a little odd, I don't know about Autodesk CFD though. The general consensus is there is not a real need for ECC ram. 128GB isn't too much, that's just two 64GB kits, and would be cost around $500 total, so why not. It would fit in an ATX tower if the motherboard was an ATX motherboard, and its not, so you will have to get a case that accepts extended ATX motherboards, not just standard ATX. That Power supply only has one 4+4 pin for CPU power, you will need two. I'm not sure if you can use one of the other a PCI-E connector in place of the CPU power, There are differing opinions out there: here is an adapter: http://www.newegg.com/Product/Produc...-006-_-Product You may want to do some more research on if you can do this or not, but The safest thing would be to get a server power supply that has two 4+4 CPU connectors. I can't tell if that motherboard comes with 6GB/s sata cables or not, but most hard drives don't come with them either, so you might want to get two of those. |

i will also have to take a look at the case, i caught that the mobo was "extended" but i did not really think about it. as far as i know at this point, the new software ( the Autodesk stuff) does not have any limitations on cores or configurations. i will have to find out about our older software (the fluent). thanks. |

Forget about making it last 5 years. You will want to replace it in two years or so. Performance (if mostly in terms of the number of cores) has been escalating far too fast to justify hanging on to old equipment that long. Remember that with CFD, software and manhours cost far more than the hardware. That board is extended ATX, so you will need a chassis that can accomodate it. 128 GB sounds like an awful lot of memory for 16 cores.

For this type of question, I would also consult pcpartpicker.com. The only drawback is that if you want multiple processor motherboards, pcpartpicker will not be able to help...you're best to check another place for advice (reddit /r/buildapc or on overclockers.com). Hope this is helpful.

You need to look at the type of work requirement for the amount of memory that will be needed. 4GB / core is quite a sweet spot, in terms of memory cost and availability, as well as being a kind of limit on performance. If you are running such big models that you are actually using around 4 GB/core, chances are that runtimes will be unproductively long, and you need to look at a bigger facility. Yes, check the Fluent licensing. AFAIK, parallel Fluent licensing these days is available in a sequence of bundles of 8,32,128,512, .... etc parallel processes. So if you have only 8, you won't be able to fully utilise your machine. If you have 32, you won't fully utilise the license. |

Yeah, i will have to get with the engineers actually using it and see which software they want to lean towards. i will also be building new CAD stations with i7's. if they want to stick with the fluent then there may not be any reason to get a dedicated computer for it, or maybe just a second CAD station.

we are going to be dropping fluent in time to use the autodesk software. does anyone have any thoughts on the hardware i picked out?

Core to core Intel is faster, but when you compare overall performance and price AMD is not bad option. Quote:

it is interesting that you seem to be the only one claiming ecc ram is needed on this forum. can you tell me what problems i would run into or avoid with ecc ram? for the hdd's i am now considering a single 120Gb ssd for the os and a pair of 3tb barracuda's in raid 1 for the storage. for the dvd drive, i am going to be using a drive with 881 reviews with a 4/5 average. but that is such an insignificant part of the build to worry about. i will need a different case, because the multi cpu boards are either EATX or SSI EEB. |

Depends on the size of your problem. No use getting 128 GB if you are never going to run problems that need more than 64 GB. By the same token, if you are ever going to need 128 GB, getting only 64 GB would be a bit silly. If you don't need the 128 GB, it is definitely worth getting the faster 1600 MHz memory.

Why not 128GB of 1600? should cost about $600
