Gainward GLH 9800GT 512MB
 

Voltage of the GPU

Standard voltage = 1.13v
OVP = 1.13v + 180mV = 1.31v (seems to be rather 1.3v + 180mV = 1.48v)
Pin19 = FB, 100k resistor between pin and ground



Voltage of the MEMORY

Standard voltage = 2.10v
Max voltage = 2.45v



Measurement points

Blue = Vgpu
Green = Vmem

Let's hope for +800GPU /+2000 Shaders action :)

Doing a quick test with the first card at 1.265v Vgpu. 800/2000/1200 is GT4/03 stable, without artifacts.

830gpu, 2100sha is no-go

Increased voltage to 1.35v to see effect on overclockability and temperature.

850c = no-go; 830 is stable
2100s = artifacts/lock-ups; 2000s is just fine
1200m = still okay

Not worth to increase voltage that much. If I were you, I'd stick to 1.265v and freqs of 800/2000/1300, which is perfectly stable.

lower temperatures will probably help more

maybe 830/2000 shaders ? and rams at 1200Mhz, is that posible at 1.26 ?

1.22v GPU

Cannot show cpu

what are stock speeds of this sample?


rub it in! will ya
