has anyone had this problem with Turbo Boost?
the Sony VAIO F136 fx laptop I bought recently shut down after rendering 1/2 of an approx 4hr image sequence.
I bought the Sony to replace an older slower HP6226 laptop (still running fine, no problem with long renders requiring
100% resources) in order to cut down on render times.
When I started rendering even 1 frame with the Sony, Turbo Boost (TB) kicked in, rev'd up the fan and started overclocking
the processor. This is probably not a problem for most apps, but 3D rendering is very CPU intensive regardless of the particular
I checked the Intel Turbo Boost page, and it said the TB can be turned off via the bios. Unfortunately, the Sony bios has no switch, and
is basically useles for anything else except settting a password.
I returned the Sony to Fry's (they were nice enough to not charge me a 15% re-stocking fee).
While there, I checked the bios settings on the HP & Toshiba machines. Only Toshiba has a setting to enable/disable
Maybe Toshiba, HP and other laptops have a better ventilation system and don't overheat....I couldn't test them in store. Maybe the Sony is
the only one with a problem (or that model, or even that particular machine).
BTW, I called Sony tech support and was impressed how quickly they called me (~30 sec) when I asked for help at their website.
The 1st tier tech in Manila was curtious, but had no experience with the problem, and handed me off to tier 2 in Rancho Bernardo,
just 5 mi from my home.....ironic. But they also were unable to help or explain why the bios had no switch or tell me how to
disable TB another way.....but they'd pass it on to their engineers, so hopefully Sony will address the problem down the road.
Instead, I found and bought an ASUS G73JH at Best Buy....has a bigger screen, better GPU, [b]AND[/b] is very well ventilated.
In fact, you can hardly tell it's overclocking it's so quiet and cool. (it also has the TB, but handles it extremely well)....plus it was
The bottom line is and why I posted, is to caution everyone who is considering a new laptop.
If you will use it for 3D or any CPU intensive app, try to test it in the store to see how it reacts when under load.
Also, I hope someone at Intel will provide a firmware fix so the Turbo Boost can either be controlled to set the
max clock speed, or at least give us a way to disable it if there is no switch in the bios.
