messing with frequencies.

[o770]

this is something i was always curious about but i need someone sure about this. is there a problem on messing with the core and memory frequencies of a video card? i mean, not on 20 or 30MHz increments but far awya from that. will the eletronic compontent has a limitation wnad beyond that its dangerous to try.
also, if the default frequencies of core and memory r 175/400, is there a problem on modifing a lot only one of them? to make the card work with 90/400 for ex..

thanks.

What some people may or may not realize is that processors are AFAIK set to what they are for optimal performance. And as such when OCing something like a graphic card, were two different components can be clocked to differnt speeds you may unwitingly "unsyc" the transfer rates and actually see a performance drop, rather than an increase.

Example My vid card is an ASUS GeForce Ti200 Deluxe.
I can over clock this card to 230/530 but I actually get better performance when I clock it lower, to 225/530. At the higher speeds I get no artifacts and I can loop a 3DMark test for over 24 hours without a lockup. But I actually get better results when I clock it to the lower speeds listed.

I've heard a few people say that and actually with my old TNT2 card overclocking the card slowed it down considerably whether it was core or RAM or both...that card just didn't like to be overclocked at all

With my current card I pretty much lucked out and my highest OC speed for both core and mem has a very similar ratio to the stock speed

stock= 175/400...divide those two and get .4375

OC= 245/540....divide those two and get .4537

its true that many people have problems and actually slow down there card when they overclock, personally i've looked at the benchmarks for overclocked vs nonoverclocked video cards and IMHO its not worth o/cing. Your stressing your vid card even more than it already is ( lord knows we know how hot they get normal) just to get a few more fps , not worth it, newer cards will produce more performance than you could need again IMHO

Cyberfed I DISAGREE WITH YOU. Some people say the same thing about overclocking CPU's . just like CPU's some vid cards overclock much better than others and if I can get a 15-20% performance increase then I'm gonna do it. NO i dont "need" more FPS but I also dont need to run my cele 1.0A@1450 either. I just happen to like faster SETI times among other things.

But that's the whole point of benchmarking and stress testing, if you get errors or performance loss then you adjust your speed accordingly.

And I agree, first runs on my card prduced 3dmark score of 6900. That is not the case now.

OC

4344--->5901 stable... up to 6219 it can complete 3dmark2k1

I did it for that pure OC joy!
