Cons
- E-ATX will not fit standard mid-tower cases
- Memory capacity not stated by the seller
- Dual CPU builds need matching coolers and a high-wattage power supply
Good fit if
- Builders making a dual Xeon workstation with an E-ATX case
- Users who want the newest LGA 2011-3 socket for Xeon E5 v3 or v4
Skip if
- You have a mid-tower or micro ATX case
- You only need one CPU and want a smaller board
Verdict: The MACHINIST X99-D8-MAX is the fullest expression of the brand's dual socket design in this pool.
2 Best for maximum stated memory
MACHINIST X99 Dual CPU Motherboard LGA 2011-V3
- Socket
- LGA2011
- Form factor
- E-ATX
- Memory type
- DDR4
The listing states a 256GB DDR4 ceiling, the highest of the three picks, and a dual LGA 2011 layout for Xeon E5 v3 and v4. The E-ATX form factor matches the first pick, but the socket is listed as LGA 2011, not 2011-3.
Pros
- Stated 256GB DDR4, the highest capacity in this list
- Dual CPU sockets for Xeon E5 v3 and v4 processors
- Gigabit Ethernet stated in the listing
- E-ATX size for workstation expansion
Cons
- Socket listed as LGA 2011, so verify CPU compatibility for 2011-3 chips
- E-ATX form factor limits case choice
- Memory speed not stated by the seller
Good fit if
- Users planning a memory-heavy dual Xeon build
- Those who want the highest stated RAM ceiling in the MACHINIST lineup
Skip if
- You need LGA 2011-3 specifically, not LGA 2011
- You want a board that fits a micro ATX case
Verdict: A dual CPU E-ATX board for builds where the stated 256GB DDR4 ceiling matters most.
3 Best compact choice
MACHINISIT LGA 2011-3 Motherboard X99 Micro ATX Mainboard for Intel Xeon
- Socket
- LGA2011-3
- Form factor
- mATX
- Memory type
- DDR4
$56.99 price as of 2026-10-07 06:17 UTC (Details)
The only micro ATX board in the MACHINIST pool, this fits smaller cases while keeping the LGA 2011-3 socket for Xeon E5 v3 and v4. The listing states a 128GB DDR4 ceiling, which is ample for many single CPU workstation builds.
Pros
- Micro ATX form factor fits smaller cases than the E-ATX picks
- LGA 2011-3 socket for Xeon E5 v3 and v4 processors
- Stated 128GB DDR4 support
- The only mATX option in the MACHINIST pool
Cons
- 128GB is the lowest stated memory ceiling in this list
- Single CPU socket only
- Listing name shows a seller typo (MACHINISIT), verify branding
Good fit if
- Builders with a micro ATX case
- Single Xeon E5 v3 or v4 builds that do not need dual sockets
Skip if
- You need dual CPU support or an E-ATX board
- You plan to exceed a stated 128GB of DDR4
Verdict: The sensible choice when a MACHINIST X99 build has to fit a compact case.

How the picks were chosen
MACHINIST is a brand that sells Intel X99 platform motherboards for LGA 2011-3 and LGA 2011 Xeon E5 processors. Our pool held 3 MACHINIST listings, so we included all of them: the X99-D8-MAX (E-ATX, dual LGA 2011-3), the X99 Dual CPU (E-ATX, LGA 2011), and the X99 mATX (micro ATX, LGA 2011-3). We shortlisted by form factor fit, CPU socket match, and stated DDR4 capacity. Prices shown on the page are live, read from the store listing at the time displayed, and may change. Selections are based on stated specifications and seller listings; every claim here comes from those listings or from linked maker and standards pages.
Picking the right one for you
Socket: LGA 2011 versus LGA 2011-3
Two of the three MACHINIST boards list LGA 2011-3, which accepts Intel Xeon E5 v3 and v4 processors. The X99 Dual CPU board lists LGA 2011, which is an earlier socket; if you already own E5 v3 or v4 chips, confirm compatibility before buying. Intel's processor naming pages explain Xeon E5 generations, and the chipset pages list which desktop chipsets pair with which sockets. When in doubt, a board explicitly labeled LGA 2011-3 is the safer match for v3 and v4 Xeons.
Form factor: E-ATX versus micro ATX
Two picks are E-ATX, which is wider than standard ATX and requires a case that states E-ATX support. The third is micro ATX, which fits many mid-tower cases and compact builds. Measure your case before choosing: an E-ATX board will not fit a micro ATX case, and a micro ATX board in a large case leaves the interior sparse but still works. The E-ATX boards in this pool are the only ones with dual CPU sockets.
Memory: how much DDR4 do you need
The listings state two different DDR4 ceilings: 256GB on the X99 Dual CPU board and 128GB on the micro ATX board; the X99-D8-MAX listing does not state a capacity. Intel server chipsets support large memory pools, but the board's layout and BIOS set the actual limit. For single CPU builds, 128GB is a practical ceiling for most rendering or virtualization work; dual CPU boards can address more if the board supports it.
CPU support: Xeon E5 v3 and v4 families
All three boards are built around the Intel X99 platform, which pairs with Intel Xeon E5 v3 and v4 processors on the LGA 2011-3 socket. The second pick lists LGA 2011, so check the CPU list on the maker's page. Intel's processor number guide can help you tell E5 v3 from v4 by the number scheme. These are server CPUs, so expect no integrated graphics and plan a discrete GPU.
Operating system requirements
Windows 11 requires a 64-bit processor with 2 or more cores at 1GHz, 4GB of RAM, 64GB of storage, UEFI with Secure Boot, and TPM 2.0, per Microsoft's published specifications. Xeon E5 v3 and v4 processors meet the core count and speed, but the motherboard must support UEFI and TPM for a clean install. Check the board's stated firmware before buying if Windows 11 is your target.
What the listings do not state
None of the three listings state the chipset model, PCIe slot generation, M.2 support, audio codec, or the number of SATA ports. If any of those matter for your build, contact the seller before ordering. The pool data only includes form factor, socket, and RAM type for each board; everything else remains unverified in this guide.
Questions
What CPUs work with MACHINIST X99 motherboards?
The two LGA 2011-3 boards accept Intel Xeon E5 v3 and v4 processors. The X99 Dual CPU board lists LGA 2011, which is an earlier socket; check the CPU support list from the seller before pairing it with E5 v3 or v4 chips. These are server processors, so you need a discrete graphics card for display output.
Can MACHINIST boards run Windows 11?
Windows 11 requires a 64-bit processor with 2 or more cores at 1GHz, 4GB RAM, 64GB storage, UEFI with Secure Boot, and TPM 2.0, per Microsoft's published specs. Xeon E5 v3 and v4 CPUs meet the processor requirement, but the motherboard must support UEFI and TPM 2.0. Confirm those features with the seller before buying.
How much RAM can these boards support?
The X99 Dual CPU board listing states DDR4 support up to 256GB, and the micro ATX board states up to 128GB. The X99-D8-MAX listing does not state a memory capacity. Actual limits depend on the number of DIMM slots and the BIOS, so verify with the seller if you plan a maximum memory build.
What cases fit a MACHINIST E-ATX board?
The X99-D8-MAX and the X99 Dual CPU board are E-ATX, which are wider than standard ATX. You need a case that explicitly states E-ATX support. The micro ATX pick fits standard mid-tower cases and many compact cases. Measure before buying; E-ATX boards will not fit cases designed only for ATX or smaller.
