Re: connecting a pcie x16 coprocessor card

 

Hi,

 

The server in question has two x8 wide PCIe slots, of which expansion slot 1 functions at x4 speeds and slot 2 functions at x8 speeds. 

 

The x16 card that is mentioned here, if it were referring only to the connector width, then the card would not fit in. If it referred only to the speed, then the card would be forced to operate at x8 as the electrical lanes are only x8 available on the second slot and at x4 on the first slot. This woiuld result in degraded performance if the gaming application required a x16 speed PCIe connection. You may refer to section 'Standard Features > Expansion Slots' in the server's quickspecs.

 

Regards,

Re: connecting a pcie x16 coprocessor card

I know this is an older post, from January, but I was recently looking at the Xeon Phi coproc boards.

 

They require 64-bit BAR support which isn't an option until the Proliant Gen8 servers.  If there's a way to enable that on G7 and below, I'm not aware of it.

 

So besides the PCI, size, cooling and power requirements, your G5 box probably wouldn't support this due to lack of the 64-bit addressing it needs.
