[XtremeHardware.It] Core Parking on Windows 7 - Page 9

It doesn't seem to do anything for me, in WinRAR 4.0.1 anyways. Although it shows the HT cores parked when i set the power option(core parking min cores) to 0% or 10%, the cores are unparked as soon as i run the WinRAR benchmark. And the score is the same as when i set the power option to 100%. Any ideas? thinking.gif

 

The score I get is 6-6.1 thousand, so HT is definitely working.

I haven't done any benchmarking, so I can't say if this tweak works or not... I can say that setting core parking min cores to 100% disables core parking at all times. I'll post benchmarks when I get a chance, but for now I'm heading to bed.

Possible that the newest beta of WInRAR understands HT better.

If they want to reverse the change, it's easier and safer, in my opinion, to go to the control panel than to dig through the registry again.

That said, if this is confusing anyone, they should probably leave well enough alone, especially considering how hit or miss the tweak seems to be.

Yeah, it certainly seems to be working on your setup.

I get similar results in resource monitor with the Core parking min cores adjustment but I'm not seeing any performance difference in anything.

Edit: My Server 2008 R2 systems seem to have actual core parking working (even physical cores are parked), still no performance difference though, and the OS defaults to 100%, not 10%.

Need to double check somethings on my other systems...

It's amazing how much misinformation is spread around here.

Well i explained it and woundman explained it aswell and showed screens as proof, editing the attributes key and make the setting shown in powercfg, and be able to change ur settings with the gui on the fly is much easier.

If u want access to the Option trough windows just change attributes to 0 , if u want full performance change it to 100% and hit Ok there u go no need to reboot or any other stuff, u can see the change in ur ressource monitor as soon u hit ok.

And thats how it should be.

I can confirm that this did boost performance from ~4300MB/s to ~6200MB/s in Winrar 4.01. Processor usage went from about 30%-40% to 65%-75% after setting the value to 100%. I should mention that my i7 2600 is clocked to 4.8Ghz.

If you want screens then let me know and I will post them tomorrow.

EDIT: OK. Back to the default 10% setting. Changing those processor power settings via the OS screwed my OC and brought back the dreaded SB BSOD 124 when idle or at light load. Extra performance in winrar not worth reconfiguring or lowering my OC. tongue.gif

Good luck to the rest of you with trick.
