I have 2 F2-8500CL5D-4GBPK in m3a-glan. These modules are listed in QVL as 1066 memory: http://www.asrock.com/mb/memory/M3A-GLAN.pdf
"Naturally" I can not run it at 1066. One of the reasons might be that this memory requires tRC 48 but the maximum in the BIOS is 42.
I would appreciate if someone could answer these questions:
1. How come the memory got into QVL if the required tRC is not supported?
2. What's that "V" in the "Dual-channel" column in http://www.asrock.com/mb/memory/M3A-GLAN.pdf ?

Is there any workaround for that tRC?
