Asus P8Z77-V Overlcoking issue

[LGM EXTREME]

Hey all,

Im not new to overlocking and have done it since the old days of dip switches and floppy drives =00=.

Atleast a few years a go i overlcoked my 2600k up to 4.2ghz on a P8z77-V motherboard.
No problems to report at the time, all was fine a dandy.
However i was just browsing my Bios today and noticed that i apparently have 0Mhz cpu and ram speeds .
I checked the clocks and all looked fine, x42 mulitplyer on 100mhz base, no voltage changes.
My ram is corsair dominator GT 1866mhz, also stock voltage 1.5v at 1866mhz.

I then boot up and check CPUz, and it shows stock speeds and doesnt even show my ram timings.. below is all the screens.
I have already updated the Bios and also cleared the cmos just incase..

any ideas as im a little baffled to say the least, the system has been totaly stable and runs well.

Any ideas would be greatly appreciated.

It could be that your chipset drivers are out of date

Already all up to date, this wouldn't explain the bios results though.
Drivers only come into play at the os level.
I have made some progress on the clocks..
CPU is up to 4.2 again but ram clocks are off.
Will report back when I'm on my machine.

Cheers
