So underneath that passive heatsink labeled Black Series the P55 chipset is located. One single chip. Also, small detail, see the white retention clips on the red PCIe graphics slots? These are now a little wider so you can more easily unlock a dual-slot graphics card.

For this test OCZ submitted 1875 MHz (PC3-15000) dual-channel memory, especially for Lynnfield processors (low voltage). Just run it at 1600 MHz @ CAS8 / 1.65v and you'll have a blast really.

Well, one more shot of the memory, this is OCZ PC3-15000 9-9-9 @ 1.65v (2x2GB) SKU: OCZ3P1866LV4GK and mind you that above 1066MHz you need to set the 1.65v in the BIOS manually in order for it to work properly with this motherboard.
