3D score : from 2800->1800:/

[stylez]

Hello

I'm overclocking my pc attm, doing some benchmarks, and using performance test 7
Everything seems fine, but when i overclock my cpu, the 3d score drops for about 1000 points:s
Overclocking with amd overdrive.

Specs:
Amd Phenom ii x4 965 (c3)@3830 ,207x18.5 ,Voltage on my cpu:1,4375.
Zalman cnps 9700 Led cpu cooler
Gigabyte 790FXTA-UD5
8gb Geil 1333 cl9 ddr3 black dragon.
2x XFX 5850 black edition both running @775/1125.
Samsung spintpoint f3 500gb& Seagate 500gb(crappy HD).
Antec Truepower 750W

When my cpu was @ 3.4Ghz, i did a benchmark and i got about 2800 3d points
When i do it now it only gets 1800:s

I really don't know what i am doing wrong , maybe somebody here knows what's the problem?

Did you check the CPU and GPU temp.

The CPU or GPU might be being throttled as per this past post.

They are fine, cpu got 23°C idle/49°C full load (when i overclocked it to 3.
Gpu temperatures: GPU1: idle:43°C/load 75°C
GPU2 a bit less...
i don't really know what's the problem:/

Don't really know either.
Did the CPU score increase with the O/C or did it decrease like the GPU?
Maybe the bus speed has dropeed down as a result of the O/C.

the cpu score was 4500 first, when overclocked it was 4800
btw: I have to Reinstall windows 7 to get rid of this problem:/
