USB 3.0 Support for ASRock Z77 Pro4 and i5 2500k

Hi,

I was going through this video for ASRock Z77 Pro4 http://www.youtube.com/watch?v=wZdekDY2thw and the reviewer mentioned a couple of times that if u are not using a Ivy Bridge processor than you would not have a USB3.0 support on this motherboard. I doubted that but wanted to get opinions from others. I am having a i5 2500k and planning to buy the ASRock Z77 Pro4 motherboard.

Is this true?

Thanks and CHeers :)

    Not true at all. USB 3.0 support is based solely on the motherboard supporting it and has nothing at all to do with the CPU used.

    I didn't watch the video, but he may have said, or meant to say, that the PCIe slots wouldn't be PCIe 3.0 without an Ivy CPU. That is true, but that's the only thing that's based on the CPU used.
  2. the ib chip has the usb 3.0 chipset built into the cpu. on the old sb cpu you need a 3 party chipset. so it up to the mb vendor to put usb 3.0 ports on there mb or not.

    Seriously? If that's true, that's asinine, and something that I never knew. Everything I've ever known and read says that it's not CPU bound at all.
  4. OK, it doesn't matter anyway. That board does have a 3rd party USB 3.0 controller (ASMedia).
  5. After more research, it's not on the CPU at all. It's chipset based. http://www.intel.com/content/www/us/en/chipsets/performance-chipsets/z77-express-chipset.html

    All you need is a 7 series chipset for native USB 3.0, not an Ivy CPU.

    the only reason why i question it is because of all the hooplah that states that ivy bridge i3 chips dont support pci-e 3.0. a statement like that wouldn't arise if cpus had no part in that decision.

    That is true because PCIe 3.0 is on the CPU level. The extra bandwidth is only available with an Ivy i5 or i7 CPU. USB 3.0 is part of the chipset, though.

    i just totally misread the question and realized the chat was about USB 3.0. yeah thats motherboard related and has nothign to do with CPU
  9. Thanks Guys :) ... I have bought the mobo after your explanations :) By the way any of you have this combo?

    Nah, I don't have that combo, although if I was buying now, I'd probably go with the Extreme4 (for SLI support).
