Core Parking Causing System freezes

[chris635]

Hey guys,

Just some info for ya. Be careful with dis-abling core parking. I was having problems with my system freezing up while I was using online websites to check internet speed that uses flash, and on certain internet games my kids play that use flash. Everything else worked fine, high end games, stress testing etc. After a week of checking for stability on my overclocks (running crazy high voltages for this), I kept having the problem. After more test's, I re-enabled core parking and voila!!! it worked. So anything below 4.3 to 4.4 ghz there were no problems with core parking dis-abled. Anything over that however my system would freeze. On my system with high overclocks dis-abling core parking caused system instability. I hope this can anyone who is having a similar problem.

After further review, I noticed my C6 state was enabled in the bios. This was conflicting with the cores unparked at high overclocks which is what was causing the system freeze on certain flash games. Once I disabled C6 state and unparked the cores, my system ran without freezing.

Good tip, thanks for the info.

I'm new to this Core Parking and I've been researching on this, now my question here is why does Window 7 do this and do we need to disable this?

My Gaming Rig Spec is on my signature below, I would like to know if I have to do this?...

I'm also new on OC I don't know if I really need to do that as well.... Not long I learn to set my Memory to X.M.P @1600:p

For an improvement in performance, I disabled core parking using the Lasso method.

It is better and easier than modifying your registry imo. Lovely bit of 64bit software.

Thanx for the info will check on that, but I need to know if I have to do this? being that I believe to have a great built system.

No you don't have to do it EXILE157.

If you are happy with what you have, stick with it. For energy conscious people, Core parking saves a little however I want all cores on demand for gaming. With my setup I noticed a difference using Lasso.

The problem is that Window's default power profiles are configured far too aggressively when it comes to core parking, especially on workstations. A number of complex parameters control when a core should be parked, and Microsoft tuned heavily towards power savings.

The core parking settings in Windows are implemented as parameters of power plans (aka power profiles). That means you can, for example, disable core parking for the High Performance power plan, but leave it enabled for other plans. And that is exactly the desired tweak for most users: disable parking only for high performance power plans.

I have been using the process lasso method just like meanmachine is doing for a while now. I agree, it is a much better method.

Good info here, now I could care less about my energy :cool:, Now this is the thing why I'm asking these questions because I've read multiple threads on different Forums on this and all have different opinions on this Core Parking.

Now what I did before was I went into Control Panel > Power Option > Power Plan and set it to High Performance, I go into BF4 then put it on Windows Mode > right click Taskbar > Task Manager > Resource Monitor > I see my Cores from 0 to 11 which is 6 Core with 6 Hyper-Threads, now while BF4 is running I notice 7 Cores Unparked and 5 Parked, I really don't see if that's really making a difference in my gaming or in overall performance on my build.

Again this subject to me has been very interesting and would like to know more about this, before I go into that software you had mention and to see if those 5 that are Parked really makes a difference.

Now which one do I download? I see this

-Download ParkControl - Live EXE. Simply run. No install.
-Download Process Lasso - Restrain CPU hogs. Includes ParkControl. Installer

-Process Lasso v6.9.1.0
-Process Lasso v6.9.1.1 beta

-Dev build
v6.9.1.1 beta 32-bit
v6.9.1.1 beta 64-bit


This disables Core sleeping.

Use process lasso v6.9.1.0. 64 bit if using a 64 bit version of windows. You will have to configure core parking for what you want it to do i.e unpark cores for high performance mode. You can set different power modes depending on what software you are running at any given moment. I use balanced mode for normal use. When I play games it is set to switch to high performance with cores unparked, and when my system is idle it goes to power saver.
