Hello everybody.
I have these results with overclocking Sapphire 3600 ddr3

1- Rivatuner 2.09 : no clock detection OC impossible

2- Atitool 0.27b : clock detected but OC impossible because seems that driver is setting it to default immidiatly.

3- Modding bios with techpowerup RBE 1.10 : Bios Modded but driver ignored to detect the card as ATI and device is completely unverified to be an ATI (I had this late 4 year ago with R9600 those days Rabit worked in this problem)

5- Modding bios with CBABE 0.97b:Bios Modded but all clocks stay in last time defaults!The bios editor reports higher clocks but driver ignored these clock.at this time this modded bios works in half speed of the oreginal bios!

6-ATi-try tool 5.22.07 : System shows BLUE screen after calculating new clocks.

Seems sapphire guys are working hard to push people buy OC versions that are original boards with light tweaks.

Seems Ati-tweaking guys today are not able to support new HD3xxx series and ATI new drivers.

Thank you guys for your help!
I have already find a program that it works:

AMDGPUCLOCK
It is not user friendly.It can not test clocks.But it works.
also I made a .bat file in startup to clock my card in startup.
It is also a good program for crossfired cards.

start c:\AMDGPUClockTool\amdgpuclocktool.exe -I=0 -ENG=800 -MEM=900 &


for device2 : -I=1
ETC.
Good work AMD-SUB team!
