Ok, ok, my mistake.
This is your board's relevant part
3 x PCIe 2.0 x16 (dual x16 or x16, x8, x8)
2 x PCIe x1
1 x PCI
The 2 PCIe x1 are 1.0. So I'm still right.
I think you are a bit confused between PCIe interface lenght (the number of lanes) and PCIe version.Newegg.ca - SYBA SY-PEX40039 PCI-Express 2.0 SATA III (6.0Gb/s) Controller Card

The card linked has a x1 PCIe interface. x1 means that the interface length is short, and there is only one PCIe "lane" (one for up and one for down transfers).
The PCIe version (the 1.0 and 2.0) determines the speed of each of such "lanes". A 1.0 PCIe lane gives you at max 250 mb/s up AND down per lane. A 2.0 PCIe lane gives you 500 MB/s up and down per lane. A 3.0 PCIe gives you 1 GB/s up and down per lane (if both card and slot are PCIe 3.0).
This means that a PCIe 2.0 x1 card is equivalent in bandwith to a PCIe 1.0 x2 card, but the 1.0 card needs twice as much lanes.
"Backwards compatible" means that a PCIe 2.0 card can run at PCIe 1.0 speed if it is placed in a 1.0 slot (and it's actually logic, the faster interface is bottlenecked by the slower one).
So each of its 2.0 lanes will work at half bandwidth, and it will be as if you bought a PCIe 1.0 card.
To get more bandwidth and get decent score in that benchmark you must place that card in a PCIe 2.0 slot (as you cannot really do anything else with the x1 slots on your mobo as they are too slow for a SSD), which in your board is one of the big x16 ones for additional graphic cards. This way even if the card will still have only one lane (as the card is still x1) each lane has 500 MB/s which will be enough to run the SSD.
It will waste 15 lanes, but at least the only lane it uses will be a PCIe 2.0 lane, so you get the full 500 MB/s you so desperately need for your SSD.
Can you please trust me a little and try it? The benchmark will prove me right.

I will answer later, some training at my job I read fast
My fault the link I sent with the mobo said Rampage Extreme
I took fastely the picture.
So if I understand rightly, you asking to me to use a 16x with a 1x lane device?
I understand the fact of pci 2.0 and lane 1x 2x
I think I just read fast and had to find a solution when I bought the adaptor.
OR maybe read wrong spec...
So my fault lol
I will bench my 6gb sata from marvell even Ive seen many trouble from this controller.
Will se what happen but at this time I cant do for the moment.
I have to re-read what you said
Have to go
Yes, because it's the only way to have it run at 2.0 speeds with that board.So if I understand rightly, you asking to me to use a 16x with a 1x lane device?
From the specs you linked, they say that drives connected to that controller can't be used for boot drives.I will bench my 6gb sata from marvell even Ive seen many trouble from this controller.
Marvell® PCIe 9128 controller : *1
(and quite a bit below, last line under Note)
*1: These SATA ports are for data hard drives only. ATAPI devices are not supported.
And in general, that controller seems to be crap.

ATAPI devices are also "speaking ATA", as the ATA physical interface and protocol are still being used to send the packets. On the other hand, ATA hard drives and solid state drives do not use ATAPI.
ATAPI devices include CD-ROM and DVD-ROM drives, tape drives, and large-capacity floppy drives such as the Zip drive and SuperDisk drive.
Yes, but the sentence before the one for ATAPI says that the port supports such drives ONLY if they are data drives. Not system drives.
There is noting stopping you from trying to do it, but if the spec sheet of your board says it's not supported, then it's likely not going to work.
Your distrust is hurting my feelings. No seriously, I know what I'm saying. PCIe is designed to be smart enough enough for that to work without any issue.How willl be safe the setup a card 1x lane in a 16 x lane -.-
From wikipedia article about pci-e please see the bolded parts:
And googling Will a x1 pcie fit in a x16 slot? turns tons of positive answers, even people that ran x16 graphic cards on x1 or x4 Pci-e slots and made a video about it (slight slot modification).wikipedia said:
Or people that run 4 cards each from a x1 slot for bit-mining (using the graphic cards as badass calculators to do very hard math, their game performance would totally suck with a x1 slot)
Did you read the wikipedia article?
No danger at all.
PCI-e is designed to be able to do that without issues.
