I'm a little curious about this, I heard a few places that overclocking this, from the stock of 100 to a higher number between 105-120 can increase system stability, GPU stability and even better overclocking potential.
I also heard that it can destroy your graphic card, and disable hardware like Sata HDD, sound cards and stuff.. I don't know how much of this is truth.
If anyone can enlighten me on this, whats true, whats false, what to take care for, etc?
Actually someone did a pretty in depth test here recently and posted it to the forums. It was the most comprehensive thing I have seen since the early days of PCI-E. I forgot who it was. Sorry about that, it was really informative.
The end results were just a few, like 2 or 3 more FPS. Not worth the risk of frying your GPU.
It's not surprising that there is little improvement in frame rates. Overclocking the PCIe bus might improve i/o to the card, but it won't affect the real bottleneck - the rendering engine deep inside the card.
^ I know. It's kind of getting annoying answering all these OCing noob questions over and over again. I avoid answering most of the "I want to water cool" type threads as people just won't listen and don't do their home work. I miss the good ol' days.
Btw, have you posted this any where else? (ie. XS,etc).
Also, did you try to increase the PCIe voltages? I know in the older days (775, C2Ds) increasing PCIe voltages tend to allow you to OC the PCIe until about 140-150Mhz. The highest I'v seen is 147 Mhz or so.
