Multi 5820k CPU in a desktop or workstation?

sharonyue · December 17, 2015, 05:34

Hi guys,

Now I have a desktop with one 5820k, x99 motherboard, 16G RAM.

Im wondering can I have a desktop (or workstation) with more 5820k CPU?

Thanks.

Not with a shared memory architecture. You can only fit one I7 processor on a mainboard.
The Xeon E5-2xxx, E5-4xxx, E7-4xxx and E7-8xxx on the other hand have a higher scalability.

If I select this: http://ark.intel.com/products/82763/...Cache-3_50-GHz

how many processors I can have for one mainboard?

Thanks.

The spec sheet says "Scalability: 1S Only". So only one CPU.
Hint: the first digit of the 4-digit model number tells you how many processors you can have on a single mainboard. Hence only

can be used on a multi-socket mainboard.

Woo, This is really helpful! Thanks!

You can of course run two (or more) separate i7-5820K computers in parallel though, and distribute a single CFD simulation across them.
You would connect the two via gigE or Infiniband network.
