Results: Cinenbench R11.5, Overclocking, and Power
Cinebench 11.5This particular benchmark is not only CPU bound, but it can show distinct differences if memory performance is not exactly there in a motherboard implementation.
We see a very small advantage in this test with the Extreme, but it is minimal at best.
Overclocking and Power
For such a busy board, the Extreme overclocks right at the same level as the less expensive (and a bit simpler) Crosshair IV Formula. I was able to achieve a FSB speed of 330 MHz fairly easily, with the usual hiccups at the 250 MHz and 285 MHz marks. The HT ratio had to be turned down of course, but this is still a nice overclock when considering how many locked processors there still are in the AMD world.
The board was just as stable at higher overclocked CPU speeds, and the Phenom II X6 1090T was able to reach 4 GHz. The coolers did not heat up dramatically, though the little fan did spin up a little louder. Stability at that speed was good, and it was again very easy to overclock with a Black Edition processor.
In terms of power consumption, it hits right where I was expecting. There are a lot more components on the board as compared to previous tested units, and so it is expected that it’s idle and load power will be higher.
Idle power is in fact higher than the Formula board, but once things get moving they pretty much even out.



Hey I am so grateful I found
Hey I am so grateful I found your web site, I really found you by accident, while I was looking on Google for something else, Regardless I am here now and would just like to say cheers for a tremendous post and a all round entertaining blog (I also love the theme/design), I don’t have time to browse it all at the minute but I have book-marked it and also added in your RSS feeds, so when I have time I will be back to read a great deal more, Please do keep up the fantastic job.
