ASUS 9800GT 1Gb OC problem. [SOLVED]
Brand new card with Accelero/turbo module installed, 55C max temps.
Using Rivatuner 7.11 to OC. I seem to have hit a wall on the core. I can run at 750Mhz with no artifacts, but when I try to go higher, it does not register, or stick. On the slider I can set it to 775 and apply the setting, but the OC does not show up in the monitoring tool, nor in ATiTool.
Neither will read anything higher than 750, even though the slider shows different.
I tried EVGA's Precision tool as well with the same results. As soon as I try to go above 750Mhz, the slider simply reset's to the previous highest setting (750). Sliders are unlinked.
I can get the memory to 1150Mhz and the same thing happens when I try to go higher, the slider just resets.
I tried ASUS' own 'Doctor' to overclock the card, but the core slider is limited to 750Mhz and the memory to 1100Mhz.
Is there something in the registry that is preventing me going higher?
Note that I am getting ZERO artifacts at the 750/1850/1150 settings.
I have OC'd previously owned cards this same way and each card has artifacted when pushed too far.
Stock speeds on this card are 600/1500/900
