could be you're using 198 W total, however even that seems a little high unless you're at full load. I don't think you can disable just one core (I wanted to do that on mine too), so you'll have to go to a deneb or stay at callisto.

Your RAM should all be running at the same speed. I'm no expert on the matter, but I was under the impression that all ram is essentially made the same, so the high end stuff (ddr3 1600) can run easily at 1066 with much lower timings, which in some cases might be faster. IDK. The new HDD will scream, plain and simple. When I upgrade, I'm definitely going to get myself a decent HDD, as all mine are at 60 MB/s.

Actually Rockz I've heard of people being able to disable just one core. Over on Anandtech a few people did it. I think it depends on the board.

Well that's interesting. I can only assume the longer ACC is out, the more we'll know about it, but AMD has been extremely hush hush about it. All I know is that it works, few people know why it works, and I couldn't figure out how to disable single cores on my gigabyte motherboard. In fact, I got all 4 cores to boot fine, but I was getting calculation errors while using MTY and the wallpaper was showing artifacts (which showed up in prtscrn, which was really weird).

The new 8xx series AMD boards have actually been advertising ACC and unlocking.
