It's obvious the cards has a bad VRM design and water cooling will do very very little to help that.

So is there any need to keep this thread going?
Apparently the cards throttle even at 700Mhz but I don't think the guy has added voltage yet. And can you link me to the source of these cards dying with stock volts and stock clocks and I hope is not a forum, especially not a overclocking forum lol

You seem to have it wrong, throttling is not caused by voltage. It is triggered the the max power draw is reached.

... that is also triggered by voltage needs ... :x

So the power limiter has to be removed then like it was done for the GTX 580. Was done for the GTX 580. That still doesn't make sence though because some people have benchmarks for even 775Mhz and it does show an increase in performance close to the amount overclocked

How come, some people can do these speeds and others less than 700Mhz, if it is the power draw that is limiting it. Are people trying to test their overclock with Furmark or something similar?

saulin... i'm yet to see a fully performant GTX590, with latest drivers, using those 700Mhz in all it's glory ...

While testing it, i was able to get the 700Mhz stable without OCP kicking in, getting 38500k on Vantage runs ... ( using the driver update that came just after the card was released )

Newer drivers seem to handicap the card even more in terms of actual progression space for overclock so ...

And as you know it's heavily dependent on the 3d app being run.

Comparing COD4 scaling improvement and saying, see the 590 overclocks fine is not enough.
Hence why some people report throttling at ### speed, while other people say, well I don't see throttling until ### speed, and then some say I don't see throttling at all.

Works pretty darn good, though I'm looking to SB, Ivy or BD in order to push these cards further.

COD isn't worth testing ... it runs good even on lower market cards ... ( as you say, not enough ).

You must take a full hand of different testing to see it happen ...
But... Vantage, 3DM011 & Heaven will give you a pretty overview of that happening ...

It is a 2 way problem. If you disable the power limiter the 590 burns. that is te difference between the 580 and the 590. The 580 has the right circuitry to power the gpu. The 590 has 2 580 gpus, but powered by 2 570 circuitries.

Now sure, you can say "But you pay less for the 160MPH Ferrari".

But I don't CARE! I'm buying a Ferrari and if it doesn't equate my friend's Ferrari, head are 'gonna roll!
What is "can"? It can either do 200mph or it can't. BTW the problem has nothing to do with cooling.
