ok, you don't know.
another question: if i'l bue Asus P8B75-M and use pciex16 for video, on second slot: PCI-E 2.x x4 i have full-speed for Asus RAIDr ?

or i need motherboard with PCIe 2.0 x16 x4 ? it's enought? or ?
give me motherboard name with microatx with support for my video and raidr together close to 100 usd

Yes the reason you get that speed is because of the x1. You should check your board's settings to see if it has a switch or the manual if it needs special configuration or if that particular slot is x1 although it's mechanically a x2 slot.

The Asus P8B75-M would work properly as it has an x4 slot available.

afterall i have GYGABYTE Sniper M3 and my speed on x16 is:31603

and sure, UEFI mode didn't work

also add info: in x4 slot speed of RAIDR is about 30% less than x16
in x8 it is about 5-7% less than x16 on my motherboard by all three tests: CrystalDiskMark, AS SSD and ATTO disk benchmark sumarry
