what can I do against artifacting?

Well.. i installed 2 NVsilencers recently.. and i havnt regretted doing that so far. tough, my cards start artifacting when I overclock them further then I have now. I have them at 501 / 1300 at the moment,.. but ive had it run stable at 540 - 1400 already.
now.. I'd hate to admit it, but my overclocks to the card are now restricted to heat instead of instabillity, and thats something i really dislike, lol
but.. anyone knows something i could do about it?

on a sidenote, I havnt voltmodded the card or so,.. Im just poking around in coolbits to overclock.
 
Keep it cooler in your room maybe :P

An nvsilencer should be more efficient than the stock cooler, are you sure it's all making good contact?
 
It is more efficient.. just not enough.. (appearantly). the idle temps of my cards went down by 7*C and my whole pc temps went down because the hot air of the cards get blown out of the back.
I reseated them once, so i'm pretty convinced they're right in place, I cleaned the chip's surface's when i putted them on etc.

I want it to do a better job, since i know my cards can run stable at higher speeds. (maybe I should get 2 Zalman V700's instead. :o :P )
 
Do you know the temperatures at load? It doesn't make sense that it would be heat limited now, it should be cooler at idle and a lot cooler at load.
 
the GPU is cooler. (I couldnt overclock them this far on the stock cooler, then I had to stop at 470 core clock, and 1250MHz memory).

the funny thing is.. the highest GPU temp i've seen so far was 76*C or so, and that was right after 3dMark06.
the NVsilencer's dont have a heatpipe running over the RAM like the original cooler does. I gues that isnt helping either.
 
Ah ok it's the RAM that's not going as far, that does make sense. I thought you were saying the GPU wasn't OCing as far. You could always try sticking some heatsinks on the RAM but I don't know how much that will help without actively cooling them.
 
the NVsilencer (same as the original cooler) do cover the RAM too.
the RAM on the GPU side of the card is connected to the GPU's heatsink through a 3mm thick copper plate, and the RAM on the other side is cooled with a passive alluminium heatsink. but i have plenty of air flowing past it, so i dont think this one gives the issues, but .. could it be possible that the copper plate conducts too much heat comming from the GPU towards the RAM?
 
It should be no different than with the stock cooler, if you throttle the core back to 480 or so can you push the memory higher?
