Gigabyte DS-4 Overclocking

[Dirt]

Finally got my motherboard and new setup, it’s working far from flawlessly though, and I know several others experience the same kind of problems. So I have seen several threads here at XS about overclocking the DS3 and think it’s about time to start a thread concerning the DS4.

For info about memory compatibility on DS3/DS4/DQ6 I recommend this thread:

And for the latest BIOS´es for DS3/DS4/DQ6 this thread:

Info about OC on DS3 this is the one to read, some settings and issues applicable to the DS4 is discussed.

I have tried several BIOS now on the latest Beta F5b, the problem i have is that the system isn’t stable when booting at 400Mhz, occasionally it will work but if i shut it of and leave it for a while and then turn it on again its always "on for 3sec no picture an then of and on again and over and over" nothing else to do than CMOS. I have tried to turn legacy USB support of, disabling all throttling, PCIe lock @ 100Mhz, slack timings, high voltages, low voltages, but it simply keeps fu**ing up during boot. Its especially strange since the system can clock to the frequencies below with EasyTuner but the same voltages and settings is a no go even at 8x400
