Shuttle SX48p2 deluxe, problem with qx9650, stuck on multiplier 6

[jrturbo]

Hi Guys

I hace had my shuttle for a couple of years now and although it has been very reliable, my quest to try and squeeze all of the potential of a qx9650 whilst keeping it quiet has led me to modify my shuttle to improve its cooling, my first step was to install a noctua NH-U9, this was an improvement over the original ice cooler, but a larger cooler would have meant doing away with the optical drive, so the only option I could think of that would allow me to keep the optical and improve the cooling was to fit a compact water cooled solution (I opted for a Corsair H60) which I have now installed.

Well the problem is that I am not sure my qx9650 hits full speed, if I set up as standard for example, multiplier 9 x 333 fsb = 3ghz when I stress the system with prime 95 whilst running CPU-Z its shows all cores under full load but according to cpuz its running at multiplier 6 x 333 fsb = 2 ghz, Core temp gives me the same result, yet windows in system properties tells me its running at 3ghz and so does speedfan, but these 2 last programs dont seem to detect any change in cpu speed regardless of the fact wether the cpu is idle or under load, so I am not sure if my shuttle is working correctly, it has only started doing this since trying run at a stable 4ghz in the last couple of days, by the way I have tried running different FSB speeds between 333 and 400 and multipliers and it seems stuck in mutliplier 6 when I check it with cpu-z.

So far I Have tried :
* reseting bios, and selecting the correct option in the bios, no change.
* format the hd, and clean instalation of windows 7 ultimate 64 bit and all its updates.
* checked the energy profile in the control panel, and have tried balanced and hi performance.

Any sugestions what to check next or what other programs I could use to double check things?

My next move is going to be update the bios to the latest version just in case, I have the Q bios and intend to installs the latest S bios, hopefully its not cpu or the mb at fault.

Hi guys

I have also tried swithcing off in bios C1E to disabled which should force it work at full speed, aswell as disabling anything else that might affect the cpu, execute bit, virtualisation, spread spectrum.etc

The problem is that sometimes after I clear the cmos and reset the bios it seem to work ok, but if I alter any the settings in the bios and reboot it the problem comes back again.

I am lost at present. any sugestions ?
