Initiating all 8 cores through MSCONFIG

post #1 of 3
Thread Starter 
Hello, guys

I was doing some searching through many databases on how to increase performance of Windows 7.

Here is my main question:

Would you initiate all of 8 cores of my AMD 8320 CPU (through MSCONFIG), or would you keep it at 1 core?

Some people swear increasing the amount of cores actually does slow down system, but does it?

Since others claim it starts Windows faster, etc.

1. What about power consumption?

2. Would that increase the temperature of the processor, or would it remain the same?

3. If you go 1 core vs 8 core in MSCONFIG, can you explain your reasoning as I'm getting mixed views at this point.

I trust a lot of people here, so I figure I rather post on this forum.

Let me know, would love to hear your point, as I'm 50/50 on this issue right now. thumb.gif

I can see both points, but question is where the truth...

By some strange occurrence when I installed Win8 everything seemed pretty slow, so I checked with a few programs and found that it's running on only one core out of 4 that processor had. After checking at Msconfig it really was showing only one core. When that was rectified system took of at expected speeds. I knew about that setting but believed that it was only for boot time which was wrong. I imagine that some single threaded apps would run just fine with only one core engaged but to run better, I seriously doubt. As far as processor using much less power, I doubt that too, unless all but one of the cores are shut of at BIOS level.
I really can't see how running on less cores could help performance at all. Win7 and 8 make a decent effort at balancing core usage (not perfect but still...), did not have XP on a multicore system so never even checked on it.
If you use a program that shows how many and at what percentage cores are engaged while multitasking (even SpeedFan shows that) you can easily check and see what is going on at the moment and decide by yourself.
While the speed does not scale up directly with higher number of cores (like : an 8 core is not 8 times faster than 1 core with all the software) for properly written programs more cores must be better with processors at same frequencies.
Single core processors rely on idle time to do multitasking but still require only one thread but multicore have much better choices.
Looking logically, an OS does not run only one process at any time. There are caches to consider also memory management and all other kinds of stuff that is constantly running in the background, so if they are balanced thru all the cores it leaves a lot of time and space for a single threaded application to run in it's own space.

Thank you, that's the most thorough explanation I have heard so far thumb.gif

Makes perfect sense to me smile.gif
