Bill, in CPUz the SPD tabs should give you the timings for different frequencies. Those are the tested frequencies and voltage. I think your problem may be that when you switched ram, the timings and voltage were still set in BIOS for your old ram, so your computer was trying to run the new ram at the old ram settings. You will find that 2T is a little more stable than 1T, but 1T gets slightly better performance, not that you would notice it. If the ram will not run right at the SPD settings, I would run memtest on it. None of the timings or frequencies will make much difference to your daily use. You won't notice very much difference. But, if you run benchmarks, there will be a difference. But, unless the motherboard is not compatible with the ram, the ram should run right if you use the timings, frequency and voltage listed in the JEDC values oh the SPD tab in CPUz. Hopefully, I answered your questions, most of them anyway.
