lol yup. just like most things...as they improve over time...they get more complicated...and you need to know more than before to operate at optimum.

Hello guys,

For some reason I seem to be having a bit of trouble with the USB 2.0 headers on my Extreme4. I've tried plugging in my Corsair 650d's front usb ports into all three of them, but none of them seem to actually give me any connection. It worked just fine with the last mobo that was in there, so I'm assuming it's the extreme4...

Any ideas?

Well the USB headers are kind of goofy. First off make positive that you do not plug them into the 1394 header. Secondly make sure the wires are good and thirdly make sure you are truly plugging them into the 2.0 header. The usb headers for my 2.0 ports work perfect at the front of the case. Also remember if you are using 3.0 headers you need the proper drivers installed to use them, (intel drivers for intel ports and asrock drivers for asmedia ports). These are all things to go over and I would double check in the manual before you proceed any further. Also verify your chipset drivers are installed.

Thanks, though not providing a direct sollution, your post made me realise what I was doing wrong (and, in extension, what an idiot I am), so a big thank you and a +rep for that smile.gif

The rest of the mobo is working great, so I couldn't be happier with it right now!

:O for me, overclocking Sandy Bridge on Z77 was the easiest thing I've ever done :O. Not to mention my overclock was related to only lowering the voltages, instead of raising them lol biggrin.gif 1.56v PLL (or whatever the minimum was) -0.30v @ offset + LVL3 load line calibration and stock VTT resulted to a stable 4.5ghz. I did few tests on 5ghz but never bothered to see if it was stable as 4.5ghz is perfectly fine + perfect temps in a hot 28-30 degree room.

Not to knock your overclock but things get sticky after 4.5ghz. I for one can attest to that. I happen to be stable at 4.6 and couldnt get stable at 4.5. Hopefully I can go higher.

everything is good again, thanks for the help

I know, but let's be honest. Who needs more than a 4.5ghz i7 CPU redface.gif Even though mine can surely do ~ 4.7-4.8ghz stable I wont bother playing for hours cause I wont even feel it.
Just saying that ~ 4.50GHz is a peace of cake on these chips. I got the right settings for like 5 minutes. If you played around overclocking LGA1366/LGA775 CPUs you will know they are a lot more tricky.
