I have a Samsung Series 5 laptop with an Intel Core i5-2467m process @ 1.6Ghz. The processor supports Intel Turbo Boost up to 2.30 Ghz according to the specifications. The i5-2467m is a dual-core process with HyperThreading, so there is a total of four (4) virtual cores in Windows 7 SP1.
I've installed the Intel Turbo Boost Technology Monitor v2.6 to monitor if Turbo Boost is enabled, and set it to "Always On Top."
I followed this process to max out the CPU:
- Open (4x) PowerShell instances
- Set each instance's affinity to a distinct CPU vCore
- Ran this code in each instance:
while (1 -eq 1) { }
Unfortunately, after maxing out all 4 cores, my laptop got hot, but Turbo Boost never kicked in.
Any ideas on how to ensure that I'm getting the 2.3Ghz Turbo Boost capability of my laptop?
3"Unfortunately, after maxing out all 4 cores, my laptop got hot" That's probably why Turbo Boost didn't kick in - your laptop's cooling system cannot handle overclocking all four (virtual) cores. What happens if you run just one or two PS instances? – Indrek – 2012-07-01T20:46:40.063
I tried a bunch of lighter tasks, but never saw it activate. After rebooting the unit, it finally started working. – Trevor Sullivan – 2012-07-01T21:22:41.747
