So as you can see the frequency looks a bit off. It's correct though. Power management and the combo of Turbo mode make the Clarkdale based 661 processor very dynamic in terms of CPU clock frequency. We indeed spot two physical CPU cores and 4 threads.

Cache memory. The Clarkdale generation processors will have a 32KB L1 Data cache, 32KB Instruction cache, 256KB L2 cache per core. Then there's a nice L3 cache that is shared in-between the two CPU cores which is 4MB in total.

Here you can see that the Turbo mode works. There are five steps. If one core is 100% in use and others are in idle the clock frequency can go up to 3.6 GHz. Two cores active could be 3.5 GHz and four cores stressed will be clocked at roughly 3.4 GHz.

Memory then -- up-to 1333 MHz is officially supported. We see the memory used properly clocked close to JEDEC specification, a little sharper actually at CAS8. Of course, when you start to overclock the base frequency, the memory frequency and performance will rise as well.

The H55 motherboard reads out the EPP/XMP/JEDEC profiles properly. We have 2x 2048MB installed in this rig.

Last screenshot, here we see the motherboard information as presented by CPU-Z. Right, I just know you guys are curious about this!
