hello, by the way, the best way is to used GPU instaed of CPU ?

A smal interesting config could be both SLi GPU Nvidia GTX version ???

Thanks

Yes, GPU is much, much faster than CPU.

You can use as many Radeons or GTXs as you can power and fit in a motherboard but DO NOT USE SLI/CROSSFIRE. Games may need SLI to use more than one GPU but oclHashcat does not. It prefers to manage the GPU resources itself.

thanks you !! where can I find a motherboard with 8 GPU ?  I have 8 Nvidia quadro. somethings cheaper than a gamer's motherboard .... can I use a pci splitter https://amfeltec.com/products/flexible-x4...-splitter/ un plug my 8 card ?

8 PCIE slots and cheaper than a "gamer's motherboard". You can probably buy that in your dreams...

Or maybe check out Tyan. They do stuff like that but I've no personal experience at that high level.

dream is not so far

Keep in mind the information on that webpage is over 3 years old.

The question is : with this extension https://www.amazon.fr/Riser-extender-expr...B00IN2KOLC

Hashcat can managed 4 GPU connected into PCI Express 1X ? And a OS like a Linux or Windows can managed too...

Performance seems OK for you ?

Thanks

Yeah, those hashrates seem about right.

ok thank you, I'm waiting for my splitter to increase speed

yeah, Samsung Galaxy s6 cover is the good suggestion. GPU is faster than CPU, Samsung Galaxy S6 edge cover  can't be denied.
