Necessary to OC video?

[Coherence]

I'm not very experienced with overclocking, but was instructed on a very simple way to OC my 2.4C to 3.0Ghz without worrying about RAM timings, voltage, or other similar complications. (The Abit IC7-G allows for OC'ing the CPU clock independently in the BIOS by using a 5:4 CPU-to-memory setting.)

However, for the short time I was OC'ing my CPU, my system started crashing, particularly while playing games (KotOR, in particular), with graphics being all screwed up with odd gridlines, low frame rate, etc. Needless to say, I stopped OC'ing my system.

So, my question is, is it necessary to OC your videocard when OC'ing your CPU? Was that what was causing the crashes?

No as the cpu and videocard can be overclocked independently of one another (in other words if you overclock one it will not have ANY effect on the other)

The possibility for your problem could be:

1) Bad driver => so install another version or use DriverCleaner first and then install the drivers
2) make sure you have AGP/PCI lock fixed, because if that is not the case then when you overclock the FSB from 200 to 250 on your 2.4 C then the AGP bus will increase along with pci thus making the videocard unstable above 72mhz so you should fix them at 66/33
3) Check to see if the computer passes Prime95 torture test and is stable running all other applications but video applications. Make sure the cpu, the motherboard, or the northbridge are well cooled and are not overheating. Also the stability of your power supply could pose an issue
4) increase the AGP voltage from 1.5 to 1.6 but overclocking the cpu has no effect on the videocard so check suggestions 1-3 again.

Let us know what happens.

The slow frame rate makes me think that your temps are too high (p4's throttle back the CPU speed upon high temp).

Check your CPU temps with either the tools supplied with your mobo or with MotherBoard monitor.

If you OC'd a stock system, without taking things like cooling into consideration, then this sort of thing will happen.

Good luck
