Ok guys, I've finished up tweaking my system and my card. Bellow are the results:

System spec:
Mobo: Asus M4A77TD Pro
CPU: AMD Phenom II X4 945 Quad Core OCed @3.6Ghz
RAM: Kingstone HyperX 2x2gb @ 1600Mhz
GPU: 1xGTX590 with EK nikel+acetal water block. + beta 270.51 drivers.

I will make a little comparison between GTX295 and GTX590.
GTX295 with coper+acetal waterblock:
idle temps: 40 degrees Celsius.
load temps: 52-55 degrees Celsius (normal environment).
load temps Furmark 5 min duration 62 degrees Celsius.


GTX 590 with nikel+acetal waterblock:
idle temps: 44 degrees Celsius.
full load: 54-56 degrees Celsius (normal environment).
load temps Furmark 5 min duration 59 degrees Celsius.

I manged to OC the GTX590 to 680Mhz per core and 1800Mhz on Memory (WITHOUT messing with the VDC voltage). This is 100% safe and STABLE in any test/game/environment. Later I will try to slowly increase the voltage with MSI Afterburner in hopes of OC-ing even better but now that nVidia introduced additional layers of protection this could end up being a wild chase....at least the card won't get fried;)

I made a small clip on youtube showing the comparison between the GTX295 PCBs and Waterblocks and some 3DMark 2011 tests. I think this will be useful to people (like myself) who like dual-gpu solutions (as are the best for 3D vision) and are migrating from 295 to 590.

Hope you like it. Also if you want any more information (about performance in some areas) please let me know.

Best regards

Very nice. Did you do some comparison for performance between the GTX 295 and the GTX 590 in stereo 3D mode?

Unfortunately I didn't made a stereoscopic 3D comparion between GTX295 and GTX590. But, overall the performance of the GTX590 is significantly higher in DX10 ( as GTX295 supported up to DX10). Don't get me wrong, the GTX295 can get any game up and runing with 30fps+ in Stereo 3D in DX10. I am sorry for not being able to provide exact results about this:(

With the latest drivers from nVidia seems to have locked the voltage to 913mV and I cannot go higher then this.
Now the maximum frequencies I found working for long periods of time (without crashing the driver) are:

Core: 660Mhz
Memory: 1780Mhz.

The card has great overclock pontetial...to bad they locked the voltage to 913mV. They should have let us increase the voltage to at least 1.025V to overclock anywhere higher then 730Mhz per Core.

This is the best result up to date: http://3dmark.com/3dm11/965738;jsessionid=79519C39FA02ED80C67AA21BC2801FD9?show_ads=true&page=%2F3dm11%2F965738%3Fkey%3D4rUdEEj7uDdjTvmXBwdXEUx8pw9MpT

Card OCED @: 723Mhz core/1446Mhz shaders/ 1850Mhz Memory.
Temps in full load around 49-51 degrees Celsius.

This was tested using ForceWare 267.85 as from 267.91 up to the 270.51 the voltage has been locked at 913mV which is even lower then the reference 938mV. (what a crap)...

I've made a new test in 3DMark2011 using the latest beta drivers 270.51:
GPU: GTX590 @ 723Mhz Core/ 1446Mhz Shaders/ 3700Mhz Memory.

Test 1: 3D Vision control Enabled in nVidia Control Panel (during the test 3D Vision was DISABLED=Plain 3D)
Test 2: 3D Vision control Disabled in nVidia Control Panel (Plain 3D)

The result are interesting as are the differences (see pictures):

Test 1:

Not downloaded yet

Test 2:
Attachment:
plain3d.jpg [214.53 KiB]
Not downloaded yet


Now that is a net difference of 690 points!!!! which is ALOT!!! I am wondering why this BIG difference exists....

It is normal to have this difference when 3D Vision is activated, but the 3D is just hidden and when it is completely disabled from the control panel. The reason for the difference in performance is that when you just hide the stereo 3D mode, you still need to load up some additional things,s o that you can just press a button and to see in stereo 3D again without having to reload the application like you would have to do if you just disabled it from the control panel.

Hi
Yes, I know and it seems normal to load up aditional files, functions etc..but still you would believe the difference not to be soo big...
This explains why sometimes and OC card works perfect in plain 3D and when switching to 3D Vision the drivers crashes...;))

Anyway I think is good for people to know how big the impact is... so they can maximize their framerates if they play in plain 3D.

Best regards
