WEI is pointless, fluctuates so much that it really doesn't matter. Mechanical drives are capped at 5.9 though, so thats normal.
since its a BE, simply raise the Multi in the BIOS. Software CPU OC isn't suggested as your headroom is severely capped and stability is a big issue.
For the GPU, get Afterburner/Precision/Rivatuner. You cant OC it from the BIOS AFAIK. Theoretically you can flash the BIOS of the card itself, but hats much riskier and the software options are just as good.
