Hello.
I was looking for a motherboard with PCIe x4, I chose this one:
http://sklep.komputronik.pl/pelny.php?id=33669
But there is something weird there, in its spec it says it has two PCIe x1, one PCIe x4, and one PCIe x16 for graphics, only that PCIe x4 looks like x16.
Here is another album from the same producer:
http://sklep.komputronik.pl/pelny.php?id=22042
Which also has one PCIe x16 and one x4 each, but here you can see that one is really x4 because it's much shorter than the x16 one.
This PCIe x4 is supposed to be for LSISAS3041E-R SAS Controller
http://www.lsilogic.com/storage_home/products...bus_adapters/sas_hbas/lsisas3041er/index.html
Which runs on "4-lane 2.5Gb/s PCI Express", you can see in the picture that it's a short PCIe lane, so I understand that the first board I chose has two PCIe x16, but one of them is running at x4 speed, and this controller it will not fit it and work even though it is x4? You need to look for a board with such a short, i.e. proper PCIe x4, what is in this second board?
Regards.

It just comes down to considering the wisdom of investing in two cards and that's it.
, such descriptions appear on boxes, promotional materials, etc., etc.) while in fact it is only the slot itself in the sense of a piece of plastic and not an implementation at the electronics level.
