<pre>I also edited this piece of code (still in si_dpm.c) to let my memory clock hit
1400 MHz which is stock speed for this card, and I'm still running rock solid:
/* limit all SI kickers */
if (rdev->family == CHIP_PITCAIRN) {
if ((rdev->pdev->revision == 0x81) ||
(rdev->pdev->device == 0x6810) ||
(rdev->pdev->device == 0x6811) ||
(rdev->pdev->device == 0x6816) ||
(rdev->pdev->device == 0x6817) ||
(rdev->pdev->device == 0x6806))
max_mclk = 145000;
} else if (rdev->family == CHIP_VERDE) {
...
Not sure why it doesn't hit my 1450MHz overclock (which is flashed to the
card's bios), but I'm very pleased compared to the previous 1200MHz.</pre>
