Is it necessary to adjust the FSB

post #1 of 17
Thread Starter 
Most people on the internet seem to suggest overclocking using the bus frequency.... However, when this is done, the frequency of the RAM needs to be lowered.... Does this decrease performance?

As you can see from the photo, I just increased the frequency of the CPU itself, but then I do not increase the FSB.... Does this decrease performance?

The dilemma seems to be, either decrease the FSB or the RAM.... Am I understanding this correctly?

Also, can anyone see any problems with my current configuration... At this actual level it seems to freeze up when I run three or four instances of Orthos... But I just set it a bit below and it runs ok... About 4.1 GHz seems to be stable... Is that good for an AMD II x2 Phenom black edition?

Btw, thanks to ronnin426850 That article really explained things quite well... Luckily I have the black edition.... I think. Also thanks to Asmodean, Devilmaypoop, and Mit Namso..... You guys are helping me alot and I think I am starting to understand this for once in my life....

One last thing, anyone own need for speed hot pursuit? My graphics menu does not have a setting for anisotropic filtering.... I thought I remembered there being a setting for this on my last rig.... I wonder if it is a graphics card problem or something... Just thought I would ask if anyone knows.

If I can I always OC using core multiplier as it's much faster way to achieve your target. This is also becuase whenever I OCed using FSB the ram frequency was either too high compared to its capabilities. When I lowered RAm frequency it was too low and nothing was working so I personally prefer OC using multiplier instead of FSB if it is possible

So it seems I am on target then? Perhaps raising the FSB just a tiny bit would be beneficial... I am not too sure.... Do you think the voltages are too high for the GHz I have...

At about a 50% load under Orthos, it seems to peek at 55 Celsius.... Is this too high?

What model is it? If it's Phenom II x2 555 then the voltage seems to be fine as they are running 1,4V on stock voltage.

Its a Phenom IIx2 965..... It seems ok to you? Do you think it could go much higher than 4.1 GHz????

Maximum temperature is 62c, so you're fine. You wont see any difference if you raise the FSB compared to the Multiplier, so just stick with the Multiplier if you have it unlocked.

With your current voltage, I think you should be able to go a little higher. Temperature might become a wall though.

Seeing as your fairly new to overclocking, i would generally stick with using the multiplier for the individual components man.

The only main advantage to overclocking using the FSB is that it overclocks your other components too (cpu, ram, HT, NB) or some people do it for the challenge, but seeing as you have indeed a black edition. You can overclock all the mentioned components individually for the exact same result, plus its safer.

This was usefull to me too. I got an identical CPU so I will probably clock using only the multiplier too.

By the way Asmodean... You a fan?
