I'm using the P7H55D-EVO motherboard and 1600MHz ram, but I cant seem to get the ram to run at that speed? I've tried different voltages but the pc restarts and does nothing till I rastart it again and then displays "Overclocking Failed." Can anyone give me a stap by step solution how to set up 1600MHz?
I have changed AI Overclock tuner to X.M.P., and now my ram can run at 1600MHz but my DRAM voltage needs to bet set at 1.76V for this to work. On the RAM itself it says 1.7V-1.9V, so would it be safe to run 1.76V? I'm just wondering because it's already in the "red" area. Also my CPU(i3 530) automaticly now runs at 3540MHZ, ave. temp is 44Celsius, is this ok? Any reply will be much appreciated.
It's not safe. That RAM was intended for other architectures. The more recent Intel 1156 and 1366 sockets specifiy a limit of 1.65V on the RAM V. Also as it looks like you've noticed, when your turn on XMP with an i3 or i5 CPU and 1600 or greater RAM you lose Turbo and the power saving features and it can introduce an unintended OC to your computer.
What's happened is you've introduced an unstable Overclock. I would turn off XMP. If for no other reason than because of the large RAM V that it requires. There is very little real world difference between 1333 MHz and 1600 MHz RAM. If you want to run the RAM a little faster or OC you're computer, take the time to do it by tuning BIOS by hand. And do not let your RAM get above 1.65V. (It is possible to run with more but generally requires other changes and a large degree of knowledge and comfort with risks on the users part.)
