Precision M6600 OC session

I've been troubleshooting over the last few days and finally got it working. Turns out the CCC (cataylist control center) was causing the card not to overclock. There was no settings from the CCC to make it work either like I read online. Ending the process or not running the CCC let Trixx work properly. You don't need CCC running really at all and I may end up just uninstalling it. I don't use the functions.

Trixx 4.6.0 does not work properly with the M8900 card. It still wouldn't let the values be set and stay. But 4.3.0 does work just fine. I'm not sure what they did with the latest rev.

Check the following settings only:
... and start minimized
... and restore clocks
synchronize cards in multi-gpu config
Disable ULPS

Do not have load on windows startup checked. You may not need the start minimized or the synchronize cards check, but I have not tested it without those yet.

Make profiles for your clock settings and save under each one. To run them and get them to stay, you must hit the apply button after you load them. Run GPU-Z during to check. GPU-Z will update after you hit apply.

Screen flickering issues are resoved by changing the resolution right away, and applying. Then change it back if you prefer right away. The flicker goes away. Everytime you change the clock settings you will need to do this, even if you go back to stock.

So far I am up too 850 CPU and 1150 Memory clocks that are stable with a 3610 3DMark11 score, that's with my i5 2540M.
Temps are great, 76c GPU and 61c CPU. I arctic silver 5'd them.

I had to put a thicker layer of paste on the GPU, because the heat spreader was not contacting it fully. It was only about 65% contact! I was hitting 107c during testing until I found out. This is the reason Dell uses those thick thermal paste pads from the factory to make up for the poor quality control of the heatsink surface. I used a toothbrush and acetone, to clean it, the Dell thermal paste is stuck on there pretty bad.
