January 4, 20179 yr Hi all, I'm totally new to Unraid and I'm just starting to plan a build but just need some advice on a CPU. It's a used CPU and I want to make sure that it's not some special engineering sample or something that would be missing features. It's a Intel-Xeon-E5-2650-2-GHz-Eight-Core-BX80621E52650-Processor. Brand Intel Processor Model Xeon E5-2650 MPN BX80621E52650 UPC 675900005570 Key Features Clock Speed 2 GHz CPU Socket Type Socket F, Socket R Multi-Core Technology Eight Core Processor Quantity 1 Product Type Processor Cache Memory Level 1 Size 32 KB Level 2 Size 256 KB Level 3 Size 20 MB Type Advanced Smart Cache Expansion / Connectivity Compatible Slots 1 x processor - LGA2011 Socket Other Features Manufacturing Process 32 nm 64-bit Computing Yes Architecture Features Enhanced SpeedStep Technology, Execute Disable Bit Capability, Identity Protection Technology, Intel 64 Technology, Intel AES New Instructions (AES-NI), Intel Turbo Boost Technology 2.0, Intel Virtualization Technology, Intel Virtualization Technology for Directed I/O ( VT-d), Thermal Monitoring Technology Platform Compatibility PC Miscellaneous Max. Operating Temperature 67.4 °C Will this work?
January 4, 20179 yr What do you intend to do with your unRAID server? Do you intend to use it just as NAS or do you want to utilize other features? A Xeon is a powerful processor and can be overkill depending on how you intend to use unRAID. The CPU will work, choosing the motherboard can be a little trickier, you want to make sure you get the features you want.
January 4, 20179 yr Author Hi, thanks for responding so quickly. It will be used as a NAS (my current NAS just died). I plan to add some dockers as well as set it up as a Plex server with the NAS most likely doing the transcoding of .mkv files. Not sure about any VMs yet. I see what you're saying about motherboards. The only one I can find at the moment for socket 2011 is: Supermicro X9DRL-EF Xeon 2XLGA2011 DDR3 ECC 6SATA 4PCIE 2GBLAN IPMI ATX Motherboard and it's not even in stock. CND $475. I also like the IPMI feature. Is investing in socket 2011 sort of a limited future considering the age of the socket, DDR3, etc? The good thing is that the motherboard (if still available somewhere in Canada) supports dual CPUs. Edit: Found some SuperMicro socket 2011 mobos with DDR4 but not sure if they have IMPI yet. Example: Supermicro X10DRL-I LGA2011 E5-2600V3 C612 DDR4 PCI-EXPRESS SATA ATX Motherboard. of course, all back-ordered. One reason why I was looking at socket 2011 specifically is because I can get the Xeon-E5-2650 (not v3) for like $60.
January 4, 20179 yr There are several threads on these CPUs: http://lime-technology.com/forum/index.php?topic=46077.0 http://lime-technology.com/forum/index.php?topic=52277.msg501654#msg501654 These chips are server pulls from old corporate servers (Facebook?) that are being decomm'd. They are powerful, old, hot chips that present an interesting opportunity if you need a lot of horsepower, but they're not for everyone.
January 4, 20179 yr Author Thanks. Looks like both those threads are concentrating on the 2670 rather than the 2650 but I'm sure just as relevant. I guess the problem is finding a socket 2011 motherboard that has IPMI, preferably DDR4, possibly dual sockets for a decent price. These 2011 motherboards are still pretty expensive.
January 4, 20179 yr I understand the allure of cheap multicore Xeon's but you have to consider what you are getting yourself into. I think that socket 2011 boards will still be made for the foreseeable future, but I guess the question is, is it for you? The Supermicro X9DRL-EF is a nice board by the looks of it, but is uses expensive UDIMMS which you may not need. Something else to watch out for when researching 2011 boards is their size, they can often wind up being E-ATX or stranger sizes like SSI EEB and then you need to find a specific case to fit the motherboard which can boost the cost. If you want features like IPMI, then sure you are going to be focusing on brands like Supermicro and ASRock who make great boards, but maybe you don't need a Xeon, maybe a quad core i7 will fit the bill, and maybe it doesn't have to be the latest intel release either, maybe a socket 1155 board and an Intel Core i7-3770K are all you need.
January 5, 20179 yr correct me if i am wrong but i dont think the Xeon-E5-2650v1-v2 will work with those motherboards that support ddr4 that you are looking at using . those cpus are 2011 and the motherboard is 2011v3 and i dont think the boards are backwards Compatibility.

Correct. https://en.wikipedia.org/wiki/LGA_2011
January 5, 20179 yr Author Ah good catch. I haven't decided on what I'm going to do yet but I'll be sure to post the build and get all of your approvals before I order. Thanks again.
