I recently changed my timings in bios to what they should be because my cas was at 9 and my clock speed was really low, i finally got the settings correct but my oc in sandra says im at 733%, there is no XMP setting in bios.
Your memory specs are: 4GB (2x2GB) DDR3 1600MHz Non ECC Unbuffered XMS Heat Spreader Kit, 1.65V / 240-Pin / CL7-8-7-20 / Corsair CMX4GX3M2A1600C7.
Your mobo supports these settings.
Did you run CPU-Z? If so, what settings did it report?
Last, I wouldn't worry too much about the lack of XMP settings. Just allowing the mobo to run at default settings in the BIOS will allow the system to run reliably. If you want to manually set to the specs listed for your memory, that should be fine.
Because your CPU and GPU temps are good, I wouldn't worry about it. It may just be the temp sensor on the motherboard. Is the system performing well otherwise? Also, it could be a matter of less than optimal airflow. I don't believe you need to change your settings at this point in time.
