Cubix Xpander 2 and hackintosh

[Robert Houllahan]

Why? you can get a Asus P6T7 WS board with 7 Pcie slots, four will run at X16, which is much greater bandwidth then a Cubix.

Because we will be using a MacPro soon and will need the Cubix, the hackintosh is a stopgap until we get another MacPro (the one we have is being used for protools for sound). Also, if we do build a new hackintosh it will be a LGA 2011 build at the end of the year, which looks to be the first consumer-priced dual CPU (dual QPI) socket, and will have plenty of pci-e slots by the looks of the concept mobos out there (I know EVGA had a dual cpu lga 2011 board in the works).

Either way we have our reasons to get the Cubix…but will it work!? (-;

Thanks,

It should work it does not have drivers it is just a hardware expander.

If you can purchase the Cubix desktop 4, more slots and good heat removal.

Just want to correct some misinformation in this thread. GPU-Xpander Desktop 4, Rackmount 2, and Rackmount 8 systems all comply with the industry-defined specs for PCIe Gen2 x16, and all of them support a full 80Gbps bandwidth connection between the GPU-Xpander and the host machine, be it PC or Mac Pro. In other words, no performance hit or latency issues using these specific Cubix products.

Alternatively, GPU-Xpander Desktop 2 with the dual double-wide slots (not 4x single-wide slots) does support a full 80Gbps connection

Hi Eric,

You’ve contradicted yourself a little here. In the standard candle thread you said;

“GPU-Xpander Pro2 / Desktop 2 was limited to 40Gbps on 4-slot configurations, even with PCIe x16 HIC (Host Interface Card) connections to Mac Pro’s x16 slot. Desktop 4, with the Cubix part numbers referenced by DaVinci with the release of Resolve 8, natively supports 80Gbps bandwidth. This same 80Gbps 4-slot PCIe backplane is also used with the GPU-Xpander Rackmount 8 model (2 of them in a 4U rackmount enclosure).”

and here you said;

“Alternatively, GPU-Xpander Desktop 2 with the dual double-wide slots (not 4x single-wide slots) does support a full 80Gbps connection”

Did you mean does’NT support 80Gbps?

Also, does this necessarily matter if the enclosure is used for I/O and/or RedRocket, or even GPU (say 2x GTX 480’s)?

Thanks,

Toby

Hi Toby,

Actually, we’re both correct! Desktop 2 with 4x single-width PCIe 16-channel slots is currently limited to 40Gbps. Desktop 2 with 2x double-wide PCIe 16-channel slots supports 80Gbps.

Yes, Desktop 2 can support 2x GTX480/580 cards. However, if you want to support more than 2 cards (graphics, capture, or otherwise) at 80Gbps connectivity with the host machine, you will need the Desktop 4 or Rackmount 2 models.
