The memory runs on my Gigabyte GA-Z68AP-D3 without problems. When voltage I set 1.36 timings as indicated on 7-7-7-21. After many hours of playing there was not a crash or other difficulties. For the price really great. In Win7 the memory gets "only" a 7.7. My old Corsair memory with 1600MHz and 8-8-8-24 timings of got there 7.9. What is the reason I can not explain, however.
