does the geforce have clock throttling built in?

[borealiss]

i ask this because my fan on my heatsink failed, and had been dead for about 3 days before i had found out. 2d worked fine, and so would 3d, except that everything was sloooooooow. 2d redraw was slow, and 3d crawled from 60+ fps in q3 to 5 fps. i've heard of geforce sdr cards frying from overheating, but i'm wondering why in the 3 days mine ran, it didn't, and was actually lukewarm to the touch, and not blazing hot like it normally was with a hsf. when i put a new hsf back on, it resumed normal temp operations. anybody else ever experience this?

hmm. not really. i was seeing if an mx would work without heatsink.. it worked, but i dont remember 3d stuff. it got hot enough to where i didnt want to touch it.. oh yeah. i think it locked on me eventually in windows. heat makes it lock.

no it does not have clock throttling built in...u usta lucked out and got a good heatsink on it that kept damage to minimum

Funny you should mention that, borealiss. I observed the same behaviour a day or so ago when I decided to massively o/c my GF DDR just for the heck of it. But I couldn't reproduce the behaviour.

interesting. lets get an experiment..

those who have GF3's.. take off your heatsinks and run q3 demo for 10 hours! see if it happens. thanks. =)

I had an old gfx card and it got fuc*ed somehow and that ran SLOW afterwards, I mean real slow.

I have a GF DDR now and I find if I OC past a certain MHz for the RAM it starts getting slower as oppesed to faster, back off on the mem slider and would spead up again.

Hope that gives u some ideas

Hmmm. I OC'd the crap out of my Ultra and I lost about 1000 3dmarks one time. Clocked it back down and score went up again. Interesting...

Woohoo, we've made an awesome new discovery.

On a sidenote, have any of you noticed that sometimes when you o/c the DDR memory heavily, Direct3D games run and look fine, but OpenGL games tend to show corrupt textures? Like Q3A, Serious Sam, etc. It's weird. Because the program I use to test video memory integrity ("Artifact Tester 2&quot uses DirectDraw I think.

when i reattached my heatsink to my gf SDR, it fell off (because of the poor way i had reattached the sucker)...i was playing 3d games and suddenly my comp locked...so i restarted, where it booteed into windows fine until the asus hardware monitoring software popped up (which it does initially anyway cuz i'm not using the onboard fan header, so it thinks the fan is broken) for my vid card...everything normal, until i looked at the chip temp - it was over 100 celcius...

ha

so, let's just say that, these chips can take one severe thermal beating before they crap out, and hence your little experience.

as for o'cing, i can get my core ABOVE 170 (from 120 default) on this card...it never locks up - everything in 2d looks perfectly fine...

of course there's some serious artifacts in 3d, but it's weird that i cannot get it to lock up no matter how high i bump the core frequency...memory craps out at 215 or so...that'll lock it up.
