Hello, I have p9x79 mb and 8 sticks of Goodram DDR3-1600 4096MB PC3-12800 (GR1600D364L11/4G). The problem is at stock speed I have only 24 gb available, but at 800 hz i get all the 32 gigs. The funny thing is, the more I increase the frequency, the less memory is being detected. I tried raising voltages, updating bios, messing around with timings, to no avail. Also, this memory isn't officially qualified, so is this the end, or something can be done?
