Toshiba X205 Overclocking Itself

Hi guys!

I own a Toshiba X205 9359 for 8 months or so, and this week I installed some 2x2 GB on it. It’s a Super Talent 2x2GB 667 MHz, 5-5-5-15, all stock.

And on the very day I upgraded it, I saw on the CPU-Z the clockspeed breaking the 2 GHz barrier. Now I was looking for it on the new and found nothing.

So I opened the CPU-Z and start to wait for it, and actually it happens a lot, even running very few things, like MSN and surfing. Take a look on the screenshot. The multiplier, supposed to be 10x200, its changing sometimes to 11x200, or almost that.



Does anyone have this same behavior? Im on BIOS 1.80, and the default Vista Ultimate 32-bit.

Thanks!

cpu-z has no idea of the actual speed on Core 2 CPUs, better try monitoring with Intel Thermal Analysis Tool (a tool leaked from intel on the internet).

It is possible for a Core 2 Duo CPU on the Santa Rosa platform to momentarily overclock one core when single threaded performance is needed and slow down the other core. See the las image on this page: http://www.trustedreviews.com/notebooks/review/2007/04/17/Intel-Santa-Rosa-Revealed/p2, it's called Dynamic Acceleration.

 

Its not overclocking.

The 11x multiplier is the IDA multiplier (Intel Dynamic Acelleration). One core rests/idles at 800mhz* while the other core does all the work, thus ending up with weird clockspeeds.

CPU-z cannot detect IDA properly nor SuperLFM (super low frequency mode)

 

Very nice! Thanks guys!

I really though it was overclocking. Well, so basically my CPU can run at 11 multiplier, so if there was a Windows tool, like the old times A64 Tweaker for memory, we could overclock it!?

Best,
