Intel SpeedStep

Papercut · 25th Apr 2007, 05:06 PM

What are the steps involved to get SpeedStep working? I have an E4300 in an Asus P5B-E Plus (currently 3GHz @ 1.425V or something like that), on WinXP SP1. From day one it has never clocked itself down when idle...and in a country like Singapore, you really notice the heat dump especially when my room door is closed

Anyone have any suggestions on what I should try?

SpeedStep should still work even when the CPU is overclocked, right?

If I'm not mistaken, the E4xxx series does not support SpeedStep or Virtualization. You can check it out in the specifications here - http://www.techarp.com/showarticle.a...tno=337&pgno=0

I know it doesn't support Virtualisation but SpeedStep should still be a feature: http://www.intel.com/products/proces...t/core2duo.htm

Hmm.. Odd, I thought the earlier specs showed that it didn't support EIST.

I know this may sound stupid, did you enable Speedstep in the BIOS?

i'm not sure how does a desktop SpeedStep works

for laptop if it is disabled, it will run at minimum speed

Hah. Problem solved, CPU-Z 1.38 did not show the lower idle clock speed. Updated to 1.39 and it shows 2GHz now so SpeedStep must have been enabled all this time.

Looks like I have to address my X1800's idle clock speeds now to reduce the heat output

Thanks for the suggestions anyway
