it shouldnt be an issue if their all the same voltage/speed

Frequency Memory Timings Voltage Bandwidth Latency
1333 Mhz SPD (9-9-9-24 1T) 1.51V 12.63 GB/s 633 µs
1733 Mhz SET (8-8-8-24 2T) 1.51V 14.82 GB/s 540 µs
1907 Mhz SPD (9-9-9-24 1T) 1.65V 16.17 GB/s 495 µs


SPD timings still stuck at DDR3-1333.......

The Benchmark results above were not at all what I expected. Although it is not shocking that when set to SPD (9-9-9-24 1T) the Crucial Ballistix Tactical memory was able to clock higher than with the XMP (8-8-8-24 2T) settings I manually entered in the BIOS, I didn't expect it to clock so much higher at SPD that both bandwidth and latency was actually improved over my best XMP results. In the past before this review I have as a matter of practice always manually set the memory timings as tight as I could and just assumed that this was the fastest possible configuration. Lesson learned. So don't be like me, and potentially leave free performance on the table unused. Take the time to actually benchmark your memory with both SPD and the XMP settings before deciding how you want to run it long term. While I can make no promises that your results will mirror mine, you might find yourself as pleasantly surprised as I was. The voltage needed--or rather not needed--was also pleasantly surprising. Only at the very highest settings (1907 Mhz) did I have to bump up the voltage from the default 1.51V to 1.65V to achieve complete system stability. In fact, the memory would boot up into Windows at 1907 Mhz at the default 1.51V, but the memory fell back to operating at Single Channel mode with those settings. Bumping the memory up to 1.65V in the BIOS returned things to normal Dual Channel operation.

Test System:
AMD Phenom II X6 1090T O/C 3.75GHZ
ASUS M5A97 EVO Motherboard
Crucial Ballistix Tactical DDR3-1600 8GB
Seagate ST31000524AS 1TB SATA HD
Lite-On SHM-165S6S DVDR
HIS IceQ X Turbo Radeon HD 6950 2GB
Noctua NH-D14 CPU Cooler
Corsair 750HX Power Supply
Windows 7 (64-bit)

In the end, though, none of the minor gripes should prevent you from owning this very over-clockable memory. Highly recommended!!!
