Strange that you get full throttle when in mobile mode.
Only Intel Pentium M (Mobility) and AMD Turion to my knowledge do the speed stepping. I think the Celeron and Semperons do as well but only on laptops. Pentium 2 didn't have this feature if I remember correctly.
Yes, I do think it's weird as well... especially since I've tried disabling perpixel and it still does it. If I totally unload WB5 then it's fine. It's weird, but anoying. Also the cpu time in task manager bumps up every few seconds to 2-5% with WB5 loaded. Never did this before with WB4.6.
No difference here between WB5 loaded with StealthOS (alpha) loaded and default "Luna" theme....
Inspiron 9300 w/ Pentium M class 1.6 Ghz.
| CPUs don't max out in "speed stepping" not "utilization"? |
Need clarification on this one.
I thought you were referring to CPU usage in Task Manager.....
Please explain how you are testing (other than having Power Management Options set to "Laptop".
| Is that clearer now? |
Absolutely,
Here are the results:
Processor = 1.6 Ghz Pentium M class with the following step speeds available:
1 - 399 MHz
2- 798 MHz
3 - 1.05 GHz
4 - 1.6 GHz
Test #1 with battery power only, Power Management settings at "Portable/Laptop" =
- Processor speed with 'Luna' theme running, AV & Firewall running = 798 MHz
- Processor speed with 'StealthOS' (alpha) loaded, AV & Firewall running = 798 MHz
Test #2 with AC power, Power Management settings at "Portable/Laptop" =
- Processor speed with 'Luna' theme running, AV & Firewall running = 798 MHz
- Processor speed with 'StealthOS' (alpha) loaded, AV & Firewall running = 798 MHz
I ran the tests with WB5 loaded (StealthOS applied) to start > unloaded WB > applied 'Luna' theme via Display Properties\Themes tab > reloaded WB5 (Stealth OS reapplied). Viewed advertised speed during changes, as well as closing System Properties and reloading to verify speed had not changed.
Rebooted machine to check for any speed change after reapplication of WB5 in both tests = no change.
Speed consistent at 798 MHz throughout.
Sorry for the misunderstanding on the correct test you were looking for.
OK, great test... one last thing to test. Start playing a video or something and see if the speed gets bumped up to the full value or higher then your 798MHz. Just want to make sure it can go higher then that under load... Thanks.
Also, others can follow the same test... it could just be something in the AMD Turion camp... who knows.
| Start playing a video or something and see if the speed gets bumped up to the full value or higher then your 798MHz |
Playing video using same tests in #8 using WMP, playing Serenity = bumped speed to 1.6 GHz each time.
Note - one anomaly was the step speed in Test #1 (battery) after loading StealthOS, before playing Video was 1.05 GHz.
I also had to reboot after loading Video each time, due to speed remaining at 1.6 GHz for both Luna and StealthOS (battery and AC voltage).
Does that dialog update in real time, or are you having to reopen it each time to look at the current cpu speed?
Also did you try with an older WB skin (Say Blackcomb UIS2 ), does it happen with that too?
Its just a thought, but could you use an app which constantly monitors the speed as its possible the processor has increased clock speed due to the cpu requirements when opening a new window and not dropped back when the cpu speed is measured.
AMD have a monitor utility for AMD64 desktop cpus to watch their speed in realtime, so they probably provide one for the newer turion64 chips too.
Here is a link to AMD's page look for AMD Dashboard Demo Software (I am using an older version, the one listed on the very bottom, but the new, 3rd for top, should work the same) It show in percent instead of actual speed)

I use the dashboard both on my 64 bit Athlon desktop and on my Sempron laptop.
and it says it support the Turions.
I try looking at system properties but just opening system properties will sometime cause the speed to increase throwing off the reading.
I don't have WB 5 installed on my laptop yet, but I haven't see this problem on my athlon desktop at this time (I will have to try it on my sempron laptop later)
Thanks for pointing this problem out.
All AMD64 processors support processor speed stepping including the desktop cpus. But this problem isn't happening with the AMD64 I have tried on. The cpu speed drops back correctly.
The latest laptop Stardock have purchased has a Turion cpu in it, so I will get WB5 checked on this. It is possible WB is exposing a flaw in the power saving driver as clearly if the cpu load is near 0, then it should be dropping clock speed automatically.
One possible thought is perhaps your video card shares the main memory? AMD chips have the memory controller on die, so perhaps graphics requests require it to be running full speed for some reason.
| I had looked at the new AMD Turion powered laptops, they seemed a little buggy and latent issue than other mobile cpu's...Id go get something like a P4, I never have problems with it and OD |
No offense, but that's the tipical closed minded responce when it comes to the 2 Processor camps. I used to hate AMD as well prior to getting the new laptop... my mind has changed since then. The Turion64 procs kill everything Intel has in the mobile market right now... with the exception of the new dual-core chips just out. Dual-core Turions are right arround the corner as well and Intel will lose thier performance benchmarks yet again. BTW, run XP64 on your P4 and tell me if it works...
| The Turion64 procs kill everything Intel has in the mobile market right now... |
Kick me if I'm wrong...but if a Mobile P4 works admirably with WB5 and a Turion64 does not...then I'd be suggesting that the latter wasn't all that brilliant.....particularly if an app can expose a flaw in a processor.
Anyway....let's see what Neil can do to break this new lappy....and replicate the issue.....
