OC on AMD phenom x2 555 be. (DO i need to unlock??)

post #1 of 7
Thread Starter 
Alright, i wondering who can solve this question after i tried the test on my pc.
Its weird after i test the core. And heres the result.
All the results are test after running 1 hour prime95 blend test. No error occurs.)
PS: im in a country crossing the equtor so its hot here.(the temp is around 30~34 celcius) That means i cant OC my comp at too high frequency at air flow condition.(im using this cooler
As you can see, this is the default setting.

And after i unlock the 4 cores OCed.

OH. the speed is increase greatly. This is a good condition izzit?

Uh... but im confuse, why my computer is slightly slower after i unlocked the cores, so i turn back to 2 cores but remain the other setting.

Somehow, i can accept the fact that 4 cores are faster then 2 cores.(Of course it must to be.)

Now, 1 other question come into my mind, if i use 2 cores the cpu is not as hot as 4 cores and i'm sure can OC to a higher frequency, right??
Then i change the frequency to a higher rate and tried the test.

Hm... the 16k is same to 4 cores, and the 32k is faster then 2 cores too. WOW.

BUT.. ***??? after then all the test after 32k is slower then 2 cores?? im confuse. Who can tell me im using a 2 cores processor or a 4 cores processor is better? (i wondering why the voltage of 4 cores is slower then 2 cores in same frequency and the power comsumtion is double the 2 cores.)

I wouldn't worry too much about the times you're getting on the lower values. It's like you're just taking a very quick snapshot of your system's performance, so you're not really getting the whole picture. With the longer times, smaller fluctuations in speed tend to average out and you get a more accurate result.

And correct me if I'm wrong, but I think SuperPi only uses one core

Super Pi is a single-threaded benchmark. It only uses one core of your CPU to calculate the PI Digits. If you want a more accurate benchmark run wprime. Then you'll se a BIG difference.

SuperPi isn't that great of a benchmark, especially when using the 16k test. The time it takes is so small that any change seems more significant than it really is. You could be in the margin of error and see changes that seem significant.

In some applications, a high frequency dual core will be better than a moderately overclocked quad core. It depends a lot on what you do. With that said, SuperPi benefits more from frequency than cores, seeing as it's a single-threaded test.

It all depends on what you use your system for, for me personally i don't see a difference between my 555 unlocked to a X4 at 4ghz and with it locked as an X2 at 4.3ghz. Yes you would get a higher freq overclock with 2 cores because of less heat. i live 10 degrees above the equator also, so i keep the 2 cores locked and go for a straight high freq overclock, it produces alot less heat.

I agree.

I want to add that it seems that my old E7200 is faster than my current Phenom II X4 in SUPER-PI, so apart from the fact that it doesn't utilize multithreading, it's also an Intel-based benchmark.
