What is the point of over clocking if...

post #1 of 4
Thread Starter 
Maybe I'm missing something here but it seems to me that over clocking compromises the performance of all your hardware except your processor.

Ive been testing my video card with 3DMark05 at different clocks and so far the more I over clock my system the worse my video card performs.

Same thing with ram. At certain clocks you have to loosen your rams timing which is to raise the timing to something like 3-3-3-8, this is somehow supposed to help. But the nature of these timings is such that the "Lower" these timing numbers gives your ram lower latency which is higher performing ram. So it seems by increasing timings or "loosening" timing we are actually causing our ram to have a "higher" latency.

Also, ram is supposed to perform best at a 1:1 ratio but you cant really over clock your ram at a 1:1 ratio because at stock clock your ram is usually already at its maximum recommended output. And when you try to increase it, keeping it at a 1:1 ratio, it craps out and performs horribly. So your only option is to implement a divider at a 5:4 ratio, which again is not where your ram performs best.

Most of us are over clocking because we are PC Gamer Fanatics and want to maximize the performance of our games, but when it comes to running games at full graphics and full performance, the most important thing is to have high performance Ram and a high performance Video Card. Having a faster Processor will only improve game quality a little.

So Whats the point of over clocking your system if your video card and ram will perform worse than if you didn't over clock at all?

Overclocking your system should make it go faster, overall, not slower. Don't know why your 3DMark score was lower. When you overclocked, did you loosen the timings on your Ram? If you did, then this might be the reason why the score is lower. Also, it's worth noting that 3DMark scores your system as a whole and not just your GFX. It's your system that's slower, not your GFX.

You're right in saying that ideally you want tight ram timings, but not all Ram becomes unstable when overclocking, you just need good stuff. My Ram, for example, can run 2-2-2 timings @ ~ 260Mhz. It's a balancing act to get the best performance out of everything.

Also, running dividers isn't a bad thing. Take your example; if your Ram will only run ~200Mhz 2-2-2 and you want to increase your CPU speed then try 250 FSB with a 4/5 divider. If your CPU is stable, you now have a faster CPU and exactly the same Ram speed, which equals a much faster system.

The point is to find the best performance setup for you rig, if certian things do not overclock well for you turn them down to get the most out of the rest of you system! Yes it's for bragging rights to.
