I thought it'd be interesting to get a running score board of sorts of what core/ram speeds people are running their TNT2s (stably) at. I've got a CL tnt2 ultra doing 179 core and I was wondering how high people are managing to get theirs, and get an idea of where I should start trying. (I was crashing at 180 core until I realized it was a timing formula thing.. [1,25,1 for 178.98] and [1,126,5 for 180.41] seems that simpler clock formulas are more stable [using tntclk])
I have my viper v770 non ultra running flawlessly at 155/165 with minor modifications... using a pentium heatsink/ fan. of course i also have a small desktop fan blowing into my open case. Right now system environment is only 29° C. Probably could take it further but don't need to yet.
Well hell, looks when I wrote that. Since then I've owned A GF1 DDR, a GF2 GTS, a V5 AGP, a V5 PCI, a Radeon 64Mb, a Radeon All-In-Wonder, a GF2 Ultra, and a GF3, as soon as they bring out the 256-bit memory version. (The 128bit is no faster than my Ultra, so fsck that).
170/198 .. that was before i added ramsinks, but only with a fresh install of windows - with all my registry corruptions at the moment i only go up to about 155/175, and it still crashes! its all in a closed case tho with no other fans, so not bad.
Everyone makes mistakes.
I create disasters
170/198 is quite respectable. I was getting 175/200 out of Creative card for day to day work, and 185/220 for short benchmarking runs (would hang after 30-45 minutes) with default cooling. Thanks for responding to an old post.
I know this was an old topic, but in regards to the original question posed, I have a Creative Lab's TNT-2 (non-Ultra) currently clocked at 165 core and 249 memory. This card has been modified with a custom engineering reference BIOS and outfitted with high-speed, low-latency SG-RAM. Cooling consists of three ~40mm fans: two on the factory heatsink, one on the backside of the core. Here is an older link with more infomation about this particular card:
