Hello Chums...

A little bit of advice needed..!

Graphics Card: Leadtech nVidia 7800GS AGP.

Manufacturers default Core/Memory speeds: 375/1200

My system viewed on the Riva Tuner:

Core Clock: 2D: 275 MHz.
                 3D: Low Power. 375 MHz.
                 3D: Performance. 375 MHz.

Memory Clock: 2D: 600 MHz.
                      3D Low Power: 600 MHz.
                      3D Performance: 600 MHz

Note that my Memory Clock speed is only 600 MHz in 2D/3D mode, whereas the Manufacturers claim 1200 MHz for the Memory Clock speed..!

Is this because I am viewing the Memory speed on my 2D windows Desktop, and that when the game is actually running in 3D mode the Memory clock automatically increases to 1200 MHz...?

I have no wish to overclock the Card, but I am wondering why my Memory Clock speed seems to be HALF of the Manufacturers claimed Memory Clock speed... ...!

Cheers all......!

Paul...My memory fails me again... ...!

N.B. The first attempt was posting the question in the wrong Forum... ...!

Your speeds are fine.

Rivatuner shows the true memory speed while the manufacturer shows the DDR speed (double).

Thanks for the reply, Bjorn......!

Actually, with the "Coolbits extra tabs" add-on to the the standard nVidia Control Panel, an overclock test carried out, gave Core/Memory settings of 433/720 MHz with no increase in the Card temperature (41*C).

I'm a bit wary of maintaining these settings though, even though they boost my Frame Rates and Smoothness slightly... ...!

Cheers...!

Paul...(reduced the settings slightly to 400/700 MHz)... 8-)...!

Fiddlesticks OC till you start to see artifacts/abnormalities/high temps then back off 5 -10 Mhz.  :D

If they run fine, just keep 'em.

Even if you don't get artifacts while overclocking you're still pushing the card harder so it may still die faster than usual.

The 7800GS is a cool card though and you can also up fan speeds in Riva tuna. Mmm tuna......
