Does unparking your CPU cores increase performance?

post #1 of 15
Thread Starter 
I've heard that some cpu-bound rigs got a 15 FPS boost in BF3 from unparking their CPU cores, but I'm a little skeptical. Can anyone do benchmarks before and after unparking?

Apparently, the entire parking process causes overhead on the CPU which causes the CPU to be slower.

It should not effect performance. It was a problem with FX and thats it and that gave it 1-2% Boost.

Never heard of that. However this site says that the overhead comes when you unpark the cores or when the cores are coming out of sleep to be used, not so much that the overhead is when the are parked. It seems to be the constant scheduling and brief use that would create the overhead. Take a look at the website, he even wrote a gui to enable and disable for testing;.thumb.gif

According to the website I found Intel chips benefit more than AMD chips do.

Ok so I did this and I wouldn't recommend it. everytime the CPU started to get cooking it would BSOD and dump. It was great. good thing I ran a restore point. hehehe.

That sounds like an issue with overheating/stability.

Some people on the planetside2 forum said they got a large boost from unparking. It's not recommended for laptops though because it gives more heat.

sorry for such a long interval to reply but not an issue at all with heat and stability. I run a full liquid loop and the CPU was at stock and never jumped over 28*C. It was def the program that did it because no issues before the program was turned on and no issues after the program was turned back off.

Just as a note: This is irrelevant if you've already disabled idle downclocking on your processor via the BIOS. Just for fun I gave it a run and saw absolutely 0 change in performance, in games, benches or stress tests. My BIOS is set so that my processor stays at 4.7ghz from the moment I turn my PC on and stays that way until I shut it off. I imagine quite a few of us who're overclocking have our BIOSes set this way to increase stability.

Very true, very true. I believe have the same thing so that may be why my machine didn't like the program.
