If this is in the wrong place, please move, I thought i would get more joy here.

I have a SD37P2 Shuttle that has been working fine for the last couple of weeks. Recently (2-3 Days) I have noticed a bit of sluggishness in games, mainly BF2142. I fire up cpu-z out of curiosity and find the following

I did a bit of googlidge and find a page on how the E6600 throttles back to a x6 multi when idle but throttles up to a x9 multi under load. It also mentions you can see this in cpu-z if you stress test the cpu. As you can see in the above screenie, orthos has been running for two and a half hours when i fire up cpu-z.

Cpu-z still reports the buss speed of 266 with a x6 multi? I'm fairly sure when i first fired the machine up it was x9. Also when i first got the machine i ran 3D Mark 03 and scored just over 23,000. I ran it again tonight and it scored just over 18,000. The problem i have is, there is no option in the bios to change the cpu multi back to x9.

Anybody ever come across this before? Forgot to mention I've tried a bios flash and a reset of the bios.

Rest of the specs are.

MSI 7900GTO
2 x 1 gig OCZ PC2-6400 Dual Channel Platinum Revision 2 XTC Series DDR2
250 gig Maxtor.

Again appologies if this in deemed to be in the wrong section.
 
Would it be speedstep i wonder? I remember enabling it a few months ago and my games were sluggish and slow until i disabled it.

The 1.12 Vcore is another indication that its not coming out of speedstep mode. Perhaps windows is running in 'laptop' max power saving mode. Check what settings you have under power management (on the control panel).

To disable speedstep completely just pick Power Scheme Home/Office Desk, then even if the bios has speedstep on, windows will never use it.

If its on Power Scheme Max Battery, then it might activate speedstep, even when the cpu is fully loaded, as its trying to achieve maximum power saving. (although on my BadAxe, I get full speed no matter what I pick when I fully load the cpu.. not sure about partial load etc)

disable any "quiet' Pc" things so that it doesnt slow your pc down when your not doing anything. (in the bios) they should be in the power section of the bios

then you should be fine
