Armed with an Intel Core i7-3770K "Ivy Bridge" processor, a G.Skill-made memory kit, and GIGABYTE Z77X-UD5H, proverclocker Sin0822 managed to run a test bench with all four of the motherboard's DDR3 DIMM slots populated, at a DRAM clock speed of 3003 MHz DDR (1501.5 MHz actual). At this clock speed, the test bench was just about stable for its CPU-Z Validation. Sin0822 took advantage of the 29.33 divider for memory, which is exclusive for Ivy Bridge, that Sandy Bridge lacked. The remainder of the clock speed target was met by a gentle bump in the base clock, to 102.37 MHz (from 100 MHz). To achieve a more stable setting in which stress tests can be run, the memory clock had to fall back to 1416 MHz. What makes this feat impressive is the fact that all four DIMM slots were populated.

I got it now. That's what I was doing but it just took more force than I wanted to use.

I'm betting on Ivy we find a wide range of kits performing better than they're rated. Top end ram seems to really be held back by platform limitations.
