CPU-Control for Windows

Used CPU-Control for Windows?

Download.com staffNovember 8, 2008

The experienced user looking to quickly set CPU affinity will like the simple approach of this freeware application. CPU Control's interface is easy to read and even easier to manage. Don't bother looking for a Help file. If you don't understand what this application accomplishes, you probably don't need it.

Operating CPU Control is effortless with any of the five managed modes. With a click you can set the majority of your processes to use either CPU 1 or CPU 2. Select Automatic Mode and the application immediately splits processes across each of the two CPUs. Select processes will operate over both CPUs. Users can not force those applications to use a single CPU. However, all other processes can be individually set to one or the other CPU by using the Manual Mode. Each change is immediately reflected in the Process List. The list is easily sorted by name, ID, or CPU affinity.

The Manual Mode's nine user-set profiles efficiently store process CPU affinity sets for immediate implementation for specific tasks. CPU Control won't wow users with design, bells, or whistles. It will work well at the task for which it was designed.

No more stuttering Flash videos.
anagrammarOctober 17, 2013
Pros
Works exactly as advertised. See summary.
Cons
No bells or whistles. Would be nice if it came with a core monitor.
Summary
This is my first review of anything ever. I have an older dual core with Vista if that matters. I took the advise and downloaded from the publishers sight (discreet link, bottom of page). I suggest also downloading Core Temp from that publishers sight (don't click download installer click "other downloads" and get the stand alone) so you can monitor core activity easily. Core Control did exactly what I was hoping it would do. Older dual cores aren't that intuitive when it comes to sharing the "load" of a browser, especially while streaming any decent video. By default my browsers only utilized one core. The interface is pretty basic (similar to task manager). Automatic setting was an improvement but I found the best result was setting it to manual, right click on the process (process has to be open), click set to profile, click cores 2, then click cores 1+2. I did it for Chrome, Firefox, Explorer, and Pop Peeper (a very efficient desktop email if you're not familiar). End result is both cores working 50/50. Flash videos are no longer maxing out one core and stuttering. If it works for you, go to the settings and click start with Windows and start minimized to tray and save. I'm glad Cnet gave it 5 stars because the reviews are horrible. Sometimes programs screw up perfectly good computers and sometimes people screw up perfectly good programs. I was so happy with this program I felt obligated to pass along the recommendation (and instructions). Hope it works for you as well.
Not Worth the time

Pros
None. At. All
Cons
Does nothing at all.. and leaves a file on HDD that i had to Delete Manually
Summary
Someone mentioned it was easy to remove, yes but i still had to take a chunk off myself. another said that it works fine for him. u might want to take a closer look. I went to the publishers site to download. i installed, that was fine the application was working fine.... not, no crashes or errors but i moved everything off CPU 4, so i could keep it clean for games, spread it all across 1, 2 and 3, neatly. CPU 2 & 3 were idle, 1 and 4 were running there tits off, (at about 5% each lol). The software looks like its working but using a third-party monitor it shows that its not actually moving stuff around
Crashes immediately.

Pros
None; it's not usable.
Cons
Sadly, the negative reviews are correct. On my Quad-Core AMD PC running Windows Vista Ultimate, CPU-Control crashes immediately and starts throwing repeated errors in German, such that it must be killed via Task Manager.
Summary
I find it strange that this program is still available on CNet.com, when it clearly has major flaws that are not being addressed by the developer. Considering that CPU-Control is a complete waste of time, it should be removed from CNet's download site, IMHO.
Great!! Works as mentioned on Win XP SP3

Pros
ability to load-balance by shifting some cpu intensive stuff to the idle cores
Cons
little more in help file as i'm not sure if it shows the actual cpu utilisation picture before CPU-Control 1 takes control. If it doesn't show then i may want to see how Windoze was handling my 4 cores.
Summary
not sure why negative comments.. upon reading them i headed to the publishers site and downloaded from there.. installed it and it works like charm. First i opened Task Manager -> CPU usage history then shifted my Jetaudio playing video to Core4, immediately noticed Core4 graph jumped. Fired Winrar to compress 6GB folder containing Videos and spread it to 2Cores and then to 4Cores, noticed it happening in the CPU Usage History Graph. guys CPU-Control 1 works as mentioned !! my first review here as i was prompted by reading negative about this good product.

Pros
As the previous person said, it does uninstall cleanly. It also didn't crash my computer.
Cons
It doesn't do anything but pop up with errors once a second (the default refresh rate).
Summary
I get a popup window in German, saying that something's gone wrong (my German isn't that great, especially the technical aspect). I managed to get into the settings and found that if I set the update to a value higher than 1 (since it was updating every second and that would cause the error popups), it would then just sit there. It did absolutely nothing... from what I gather, it's supposed to show the processes running so you can alter the core options, but the window was completely blank. So it's useless unless you like the error sound and constant popups plaguing your computer time.
Crash City on Win XP SP3

Pros
To be fair it does uninstall cleanly.
Cons
As soon as I click on any option, I get a nasty sound out of my speakers and an instant crash of windows. No chance to save files or close programs, just a black screen followed by a re-boot. I haven't had a program this nasty in a long time.

Developer’s Description

Define processes you want to run on CPUs in multicore system.

CPU-Control handles the CPU-affinity for multicore-systems. Instead of running each process on both CPUs you can define it as you want it. For example, if you want to seperate the firewall and the anti-virus-software from the graphics-application.
