    yes it does also help ich10r. wow steve-o i am amazed you haven't been doing pci-e all along., its simple guys, bump the volts and the pcie speed and see what you get. same with ich10r, make sure that it is properly cooled however, bump yer volts and watch her fly! there is a sweet spot with pcie clocks however, and yoiu can go to high, introducing serious stabil8ity issues, and there is also a point of diminishing returns, which you can see in your graph above.
    Steve-o : another trick, mess with your PCI-E packet sizes, you can get some great returns from that, just be careful if running sli or tri sli (spc tri) cause if you set the packets too high then the vid cards end up waiting, introducing stuttering into yoiur video. most raid cards are designed to work at the maximum packet size that your motherboard allows. in essence when you are overclocking pcie you are allowing packets to travel faster, now imagine if you make the packets larger also! it can effect latency however also, so you need to find your happy medium, but it is usually never the default packet size of 128. i get big results at 1048.
    Note: some raid cards have built in protection and will not allow you to boot with really high pci-e clocks, they go into a self protection mode.
