RocketRaid 2720

[damonab]

Highpoint's web support requires having purchased the product and registering the serial number, and I have not yet purchased the 2720. There is no other contact or support channel available through their site that I can find. Likewise, I have Googled a bit and searched the forums here without luck.
My question is whether the 2720 will work with only four PCI express lanes available or not? I am running dual 660ti's, so there will only be 4 PCIe lanes available to the 2720 if installed. The impact on the second 660ti is not of concern for my purposes (it is only feeding an additional 2 monitors at this time). My motherboard is the Gigabyte GA-Z77X-UD5H. If any further information on my build is required, just say the word.
Thank you, in advance, to each of you that take the time to reply! =}

I would call or email their headquarters and ask for pre-sale technical support - they're bound to have someone who can answer your question. Their phone number is 408-942-5800, email [email protected]. (I got this information from their "About" page: http://www.highpoint-tech.com/USA_new/about_rocketraid_sales.htm).

Does this help? (from http://www.tonymacx86.com/98-review-highpoint-rocketraid-2720sgl.html).

Beyond that we should point out that the RocketRAID 2720SGL is a PCI Express x8 card which means that in most motherboards – X58 and X79 chipset based motherboards excluded – you’ll end up having to share eight lanes of PCI Express bandwidth with your graphics card if you’re using a discrete card...

Thank you! Can't believe that I completely missed the "About Us" page on their website. I know in the review it states it needs 8 lanes, but still not clear whether it will operate with only 4. I will send them an email and post the response here.

Hi Damonab,

Have you got a reply from them?

I have a similar setup as yours. I'm running a Hackintosh Mountain Lion 10.8.4 on top of a Gigabyte Z77-UD5H and 2 EVGA GeForce 680 FTW 4GB in SLI (which I use for gaming on Windows). I bought the RocketRaid 2720SGL and I can't get it to be recognized by the motherboard if I plug it into the PCIe x4, neither if I only remove one of the graphic cards. I have to connect the card on the PCIe x8 slot for the motherboard to recognize it.

Thanks in advance!

Same here, they do not work in 4x slots or even 8x/16x slots with only 4 lanes.
