So I am looking for a motherboard to get max out of SLI. I dont think any z97 or z boards will do dual x16 slots, your only option is a x99 . You will not see any difference between 2 x16 slots and 2 x8 slots for 2way SLI. As to 8 cards, you will need server gear as mentioned above, so 2 cpus, but I A mobo that maximises the number of PCI-E slots should exist. GIGABYTE X79 series motherboards are designed to unite unrivalled desktop PC performance with a new 4* PCI-E x16 Slot (2 *PCIEx16 or 4*PCIEx8). Auch Multi-GPU-Nutzer widmen der Frage wieder gesteigerte Aufmerksamkeit, seitdem Intels Haswell-E-CPUs verfügbar sind. SLI OP has never said SLI and I very much doubt they're after SLI. Nur Datenpakete, die beide GPUs erreichen sollen, können nach einmaliger Übertragung von der CPU über 2x16 Lanes vom Switch abgegeben werden. Einzige Ausnahme ist der Core i7 K mit 28 Lanes.

The actual performance impact of 8x vs 16x itself is debatable, in most games it probably won't matter, but if you're doing heavy GPGPU calculations with a lot of cards then it may matter. We need to build a rig with 4 GPUs either or , which will later be expandable to 8. Die Redaktion Artikel-Archiv Mediadaten Datenschutz Impressum AGB Problem mit Werbung melden. I assume this is for some kind of bench-marking rig as you can only go up to 2-Way SLI on GTX or for normal tasks as far as I am aware and you can only do bench-marking with 3 or 4 way SLI on these cards I am fairly sure. So for brute force it has no effect, for word list based attacks if you configure a larger amplifier this offsets the performance penalty of running 1x PCIe speed to the point it's almost identical in performance to 16x. Why do i need 2 CPUs it is to do with the PCI Express lanes.
