I want to overclock my visiontek GF3. I'm sure you all know it has a fan on it already, but i'm sure there is a better option out there. Also, is it necessary to get RAMSINKS?

Also, how about cooling like that offered from www.1coolpc.com where they have the fans blowing on the cards, not directly mounted on it.

Basically what are my options?

Hi there Jermus

Ok your core may require some extra cooling it may not !
The bottle neck on graphics card is usually the RAM, the faster your RAM the higher the performance. Usually a 20-25% increase is all that is required of the core. Now do not hold me to this as every card is different, but you should be able to get at least 20MHz out of the core with the stock cooler. RAM Sinks are great to help you push that RAM further and will let you get more out of your card.
(I am confused however as I thought your card had RAM sinks)

For my Card I bought a Crystal Orb:
<A HREF="http://www.commongrounds-pc.com/Reviews/ttcorb.html" target="_new">http://www.commongrounds-pc.com/Reviews/ttcorb.html&lt;/A>
:)  quite a pretty little thing and it seems to have pretty good cooling, I also added DDR RAM sinks From a Thermaltake Memory Cooling kit (Also includes sinks for your normal SD/DDR RAM)

As with all Overclocks, I advise that you are cautious. Increase the MHz by small incriments. 5MHz at a time is normally safe. Then give the card somthing demanding to do, I use 3DMark2001 and do a couple (2-3) of benchmarks. Then I have a quick 10-20 min game on UT to finish off. At the very early stages you should not have to worry too much as it should go 10MHz without batting an eyelid, but just be careful.

External Cooling will help you take the card further... As with all overclocks the cooler the case and surroundings the better and safer the component will be. Remember though its best to have blow holes in and out of the case, as you will otherwise just move the warm air to other hardware in your PC !

This is a site that should be able to provide answers to all questions you may have

Stiffler has some good advice, but I have to point out a few small mistakes.


In gf3 graphics cards the core speed is much more important than in older generations, thusly a good core overclock will net you more performance than good ram overclocking.


Also ramsinks have a capacitive effect, and can actually lower the max speed of your ram UNLESS heat is holding it back, some gf3 cards have no ram sinks and those generally overclock about as high as those with ramsinks, so just skil the ramsinks. Your gf3's ram shoudl do 530mhz+ If you find a stable overclock, try adding ramsinks, it may lower or raise your stable level. The point is try without ramsinks first.

No Overclock+stock hsf=GOOD!
