the more stress you put the card under, the louder the whine. I had the cheek to run folding@home and I thought I had opened a portal to the Banshee realm inside my PC.
TBH, I only ever had one slowdown that caused me to quite a game. I had one other, but once I hit F10 to bring up the game menu, the clocks must have reverted back. I would rather keep the power saving features enabled.
As far as watercooling goes, I will fire off some emails and do some research, and unless I get told a flat out "Reference blocks won't fit", I will likely get a waterblock and see how it goes near around Christmas. I know it is a while yet, but I really can't afford it right now, as I want/need to get my NB and MOSFETs cooled as well. Hopefully a nice little heatsink will be enough for the SB.

I can tell you now that if you use 190.68 drivers (which are new) enable performance mode and then stay away from the old 185 drivers, the matrix is about 20% faster than a gtx275. When the gtx275 is overclocked the speed difference is around 10%. Overclock the matrix and you have a further 15% over the gtx275 overclocked. SO in theory, a non overclocked gtx275 is about 30-35% slower than this card when it is overclocked. I would say that extra performance is worth the money.

So you are saying a potential (in some games the difference will be alot less) 30-35% performance increase is worth a 100% price increase? Just.... Wow.....um....ok.....
Of course I could simply go out and buy 2 GTX275's / HD4890's and have a setup massively faster than this card for the same money, now THAT is worth it.
Timing from the picture there. It always fails. Can anybody tell me, how can I overclock it by myself, or can anybody send me their specifications, clocks, timings...
Your card isn't their card, you can't just take someone's overclocked settings and think they will work for you. Just go up steadily, and bench/stresstest every overclock untill it's unstable, then revert to the last working one.

Thanks much :)
Like said above, you have to increase the clocks slowly until you find instability, then increase the voltage a bit and keep going until you get too hot under load :)
also bit probably does it right.. they take the card apart after a test run and re-do the tims.. I've done this with all of my cards and they always clock better

Ive ran one of these against the following.
gtx260 216sp
2x gtx260 216sp
gtx275
gtx295
2x gtx295
4870x2
asus gts285 MATRIX.

Please I have this one card and I am trying to overclock it... I tried the spec here on this site:
740mhz core, 1660mhz shader clock, 1180mV GPU voltage, 2820mhz memory clock and 2080mV memory voltage.
