Help needed to o/c Gforce4

I have just fixed the fan problem and got a new much better heatsink and the fan for my Gforce4 Ti4200, so decided to try and o/c it a bit. I have never done it but it seems like a simple job with RivaTuner, the only thing I am not sure is what to o/c it to. At the moment it is running at 249/445, and I presume that's basically the only thing I can change. What figures can I increase those to and still have a stable card? Also is there anything I should be aware of when o/c'ing the card?

Thanks.

Are those the default clock speeds? If so just keep going up on both by 5Mhz until you begin to see artifacts, then just back it off a little bit. I got mine to 310/610 (approx) before I began to see artifacts, so I run mine now at 300/600 constantly with no problems.

I have a GeForce 4 Ti4200 64 MB and it clocked to 300/600 with no problems. The 64 MB version uses 500 Mhz memory while the 128 MB version uses 445 Mhz memory. Raise core and memory by 5 MHz increments and then run 3DMark. If its stable and there is no artifacts, raise it again. You should be able to get 280/550 MHz without too much trouble. Tombance I just beat your score by a small margin.

Damm you! :smile: I clearly need to get a better motherboard. Even at your CPU speed the efficiency of the nForce 2 would own my SiS 745 Chipset, thats what is holding me back.

I decided to see what my Gainward Ti4200 could do because I want to compare the best 3dmark2001 score my XP2500+/Ti4200 can currently get with what it will do with a mobile XP2500+ chip. I was hoping for a stable 300/600, but it had a few artifacts at 300/595. They dissappeared when I lowered it to 295/390. I was scared to damage the card as I hope to keep it for a while, so I lowered the memory again to 585 and will use that for my comparison.

The NF2 definately helps.

What exactly do you mean by artifacts? Could you give me an example please. Also my mate gave me a Gforce FX5200, which I know sucks big time, but since it came free I thought of may be sticking a decent heatsink with fan on it and o/c it. Is it possible to o/c it to anything good or shall I just not bother?

I wouldnt bother with the 5200. If its a non-ultra even fully overclocked it wouldnt beat a stock ti4200 in most applications. Artifacts are generally things that look out of place on your screen. You usually either get 'snow' (little white specs randomly placed) or in my case I get random triangles that remain a certain colour, which I think is realted to GPU overclocking. The snow has to do with your RAM, and can apparently do permanent damage so if you see it immediately put down the clock speeds and let it cool off.

I would overclock any card, even a budget one to improve performance. Any improvement is better then no improvement imho.

I can only get my Asus 8x 128MB Ti4200 260/550 stable with no artifacts.
About how to determine artifacts, just watch the screen closely and you will know when you see them, trust me ;)
I run the Nature scene at 1600x1200 4x AA to really stress the crap outta the card when testing for artifacts.
Most people say that when you see artifacts bump it back about 10MHz and run at that all the time.

Mine is running very happily at 300/555 and haven't seen any artifacts. Wont bother going further as don't need it and it should be enough for me till NV40 or R420 come out in a couple of months.
