    tnt2 ultra overclocking woes : (

    i have a hercules TNT2 ultra with memory heatsinks and a celeron 433 HSF on it and it doesn't seem 2 like overclocking 2 much. How high have u people got your ultras with what type of cooling?

    175/230 is what I usually play at. I have 5ns ESMT SDRAM memory. Obviously it doesn't mind overclocking much. I also have a 486 socket fan on my core but no special memory cooling.

    I have had it up to 180/240, but it only lasts 5-10 minutes before I get visual artifacts or crashes. 175/230 is very stable. I did some benchmarking a while back and came to the conclusion that the point of diminishing returns is 170/220 or so. Past that I saw almost no change. I will have to try again with my new system and drivers.

    I think I remember most people (back when the Ultra just came out and discussions were more popular) getting 170-175 out of their core. People with 5ns memory easily get over 200mhz memory. I think the Hercules has 5ns RAM, but I could be wrong.

    BTW, with my setup I get Q3 High Quality Demo001 at 59 fps. Quaver gives me 46fps, and still 42fps with 4/4 texture quality. I'm running Creative Fastrac 6.34. Older 3.xx drivers would kill Quaver due to AGP texture swapping. It seems Det3 minimizes the hit. I like to play with the texture quality maxed out.
