I'm happy to say the ATI tray tools were the best program to find...
tryed everything that exists...

I have ASUS 3870x2 1Gb with one fan. (one core has cooper heatsink the second one aluminium. secon is hotter by 13°C !!!

The installation of ATI TRAY TOOLS is the problem that can make no able to O.C. both cores & set the frequencies like u wish.

At install you have to do use I2C old mode access (pre HD board only) ON
Than the rest you don't have to do anything more just this has to be marked.
Than ATI TRAY TOOLS will install properly just have preinstalled on ly the driver without the catalyst centre becouse ATI TRAY TOOLS works better than catalyst. (optimizations)

I have the latest beta version and it works just fine on XP SP3 32bit
ATT 1.7.9.1564 beta sniper.gifbuttkick.gif (it supports even 64bit, vista ...)
but couldn't get em to work on XP 64bit (ist too old anyway)

set in DIRECT3D
-catalyst AI to - off
-wait for Vertical Refresh -application preference
-texture and mipmap to -very high /still high is almost the same

look into tools&options tab
advanced tab :
uncheck enble att shared memory
check reset clock on exit
check kill ATI hotkey pooler & do this each time ATT starts

INTERESTING IS MONITORING ATT supports :
included in tools&options : if u wish so ENABLED OnScreen Display (OSD)
AND FLASH OSD tab is what u wish to monitor on your graphic card.
a lot of thing to monitor if supported, but don't check too many u won't see em like
no more than approx. 5

U CAN SET MANUAL PROFILES with fan speed and frequencys
LIKE SET CORE voltage to 1.274V but check to both cores checkbox !!!
than u can try how much u can do with the cores (like ex. 800mhz/900ddr)
and set fan to 42 (not too noisy but good work is done)
the automatic fan doesn't work too good so i set 5 profiles with manual fan speed)

I make 1 profile just to start in windows with lowest Voltage on cores and minimum MHZ. So I save electricity, temperature and graphic card lives longer.
STAY WELL 3870X2 U ROCK MY WORLD biggrin.gif

tryed O.C: on 1.274V got stable 800/900 (lower temps and less power usage)
tryed O.C: on 1.244V got stable 675/900 (did test but not for too long)
testing still max O.C. (wait 4 new power supply) THERMALTAKE toughpower 700w thumb.gif

I noticed that this graphic card has a frequency step on 27mhz and card can get crappy if not followin that step.

complements & regards to ATI TRAY TOOLS & RAY ADAMS cool.gif
