vid card overclocking
 
is there a MAJOR risk in uppping the votlages and AGP bus along with upping the core and memory speeds? :confused:

Voltage is risky. Generally, when increasing voltage you need to improve cooling at the same time. Overclocking alone increases heat, and resistance (Ohms) because of the heat. Increasing the voltage increases the heat still further, but improves stability. Get rid of that excess heat, no problems. Leave the stock cooling in place and you'll have expensive fried video card bits.

AGP bus overclocking is of such limited benefit, I really wouldn't bother. Actually I don't, even though I know my present video card (Ti4200) can tolerate bus speeds up to 84 MHz. I don't know that it really is a risk to your card; my experience is it either works, or it doesn't. My card hasn't been any worse after taking the AGP bus too far.

today i just installed the nv silencer 3 for my card, so cooling isnt an issue. i have a e-geforce fx 5900 se (5900xt with a fancy name:confused: ) also I would like to know how far i could push it and is there a better OCing program better than Rivatuner v2.0?

Don't forget extra cooling for your memory. Be careful to watch for artifacts when benchmarking.

I can't help you with suggested limits for your card. I'm stuck in 2001 video card wise. Maybe someone reading this can?

I still use Rivatuner, so if you find something better, let me know. I guess you could do a BIOS flash, but that's too risky for me.

with air I'd look for 500 on the core. I flashed my 5900 and it helped me outa bit(bumped up core with very little temp increase, coupled with more RPM on the fan from the flash usually...), I think my best was 515. Forget the memory speeds, but they jumped too.
