My Zotac 9600GT 512MB DDR3 256Bit 

3DMark 2006 = 11675
Ok or not?

You're using MSI N9600GT OC Edition as well?

Here is the test:

SPEC
CPU: E2160
RAM: Crucial Ballistix Tracer 667Mhz 2GB Kits
GPU: MSI RX3870 512DDR4 OC Edi.
Test clocks 1:
CPU: 3.2Ghz, 400x8, 1.3875v
RAM: 800Mhz, 4-4-4-12, 2.2v
GPU: Core 800Mhz, Ram 2250Mhz (Default)



Test clocks 2:
CPU: 3.2Ghz, 400x8, 1.3875v
RAM: 1000Mhz, 4-4-4-12, 2.2v
GPU: Core 800Mhz, Ram 2250Mhz (Default)



Test clocks 3:
CPU: 3.2Ghz, 400x8, 1.3875v
RAM: 1200Mhz, 5-5-5-15, 2.4v
GPU: Core 800Mhz, Ram 2250Mhz (Default)



Summary:



You had increased the 3DMark points from 10709 to 10797 by OC your RAM from 800Mhz to 1000Mhz;
Next, you had increased the 3DMark points from 10709 to 10821 by OC your RAM from 800Mhz to 1200Mhz.

Congratulation, you had gained 112 3DMark points !!!

However, what does 112 3DMark points representing??

Let's compare the FPS instead:

You had increased the FPS in the test of "Return To Proxycon" from 34.729 FPS (RAM OC to 800Mhz) To 35.090 FPS (RAM OC to 1200Mhz). Congratulation, you had gained 0.361 FPS !!!

You had increased the FPS in the test of "Firefly Forest" from 40.061 FPS (RAM OC to 800Mhz) To 40.741 FPS (RAM OC to 1200Mhz). Congratulation, you had gained 0.680 FPS !!!

You had increased the FPS in the test of "Canyon Flight" from 46.342 FPS (RAM OC to 800Mhz) To 46.452 FPS (RAM OC to 1200Mhz). Congratulation, you had gained 0.110 FPS !!!

You had increased the FPS in the test of "Deep Freeze" from 54.276 FPS (RAM OC to 800Mhz) To 54.686 FPS (RAM OC to 1200Mhz). Congratulation, you had gained 0.410 FPS !!!

In conclusion, you had gained < 1 FPS by OC your RAM from 800Mhz to 1200Mhz...     
Hahahaha...
