December 01, 2012, This is really an Old Post!After the last Z77 Bios Update I was able to set my Memory to run at 2133MHz.

16GB (8GB 1G x 64-Bit x 2 pcs.)
DDR3-2133 CL11 240-Pin DIMM Kit
DESCRIPTION
Kingston's KHX21C11T2K2/16X is a kit of two 1G x 64-bit (8GB) DDR3-2133 CL11 SDRAM (Synchronous DRAM), 2Rx8
memory modules, based on sixteen 512M x 8-bit FBGA components per module.
Each module kit supports Intel® XMP (Extreme Memory Profiles).
Total kit capacity is 16GB. Each module kit has been tested to run at DDR3-2133 at a low latency timing of 11-12-11 at 1.60V.
The SPDs are programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers.
The JEDEC standard electrical and mechanical specifications are as follows:
XMP TIMING PARAMETERS
• JEDEC: DDR3-1333 CL9-9-9 @1.5V
• XMP Profile #1: D3-2133 CL11-12-11 @1.60V
•
XMP Profile #2: D3-1600 CL9-9-9 @1.5V FEATURES
• JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply
• VDDQ = 1.5V (1.425V ~ 1.575V)
• 667MHz fCK for 1333Mb/sec/pin
• 8 independent internal bank
• Programmable CAS Latency: 9, 8, 7, 6
• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock
• Programmable CAS Write Latency(CWL) = 7 (DDR3-1333)
• 8-bit pre-fetch
• Burst Length: 8 (Interleave without any limit, sequential with starting address “000” only), 4 with tCCD = 4 which does not allow seamless read or write [either on the fly using 12 or MRS]
• Bi-directional Differential Data Strobe
• Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%)
• On Die Termination using ODT pin
• Average Refresh Period 7.8us at lower than TCASE 85°C, 3.9us at 85°C < TCASE < 95°C
• Asynchronous Reset
• PCB : Height 2.122” (53.90mm) w/ heatsink, double sided component
