I'm not sure if this is old info or not. I was having problems with having my overclock settings stick after a reboot. So this is my solution.
Anyway I just want to share it here incase anyone one else runs into the same problem as me.
All you need is ATITool. No nTune no coolbits or anything else. You DO need you unlock your Nvidia BIOS per the instructions "stickied" at the top of this forum. Thats it (aside from ATITool).
Its a simple 2 part process. First open up ATITool and set your "core" and "memory" clocks to your preference. Hit "setclock". Now at the top just below the drop down menu, hit "new" and name the profile "startup" (or anything else as long as you remember). Then hit save. First part done.
Now hit the "settings" button at the bottom left. In the new window that pops up, hit the drop down menu and click on "startup". Check the top box and bring down the drop down menu next to that check mark and click "startup (or whatever you named it). Next, check the second box and hit the drop down menu next to that second box down and click on "registry key".
THAT'S IT!
Again, not sure if this is old news or not, but I thought I'd share this just incase anyone can make use of it!
EDIT: I am using ATITool 0.26. Here is a link to a download for that, just click the button to the top right.

Okay I've tried nVid, rivatunr & atitool and they all give different max clock speeds. I dunno, maybe I should just stick with one. On ATITOOL: when I test for artifacts, it shows artifacts but says "no errors for xx:xx". What gives? Do I just notch the clock speed back until there are no visible artifactS? Also, ATITOOL will let me overclock up to 1400 mhz for the memory, wheras Rivatuner will only allow me to go to 800 or so. What gives? Is this a memory timing thingamajigger? When I set it to 1400 in ATI then open up Riva it shows 1400. I'm thinking of underclocking my card just to be different.
