My motherboard is a Gigabyte 990FXA-UD3 V4.0 with four RAM slots. All four RAM memory cards are operating giving me 32gb of RAM. Two of the RAM cards are G.Skill RipJaws 10-11-10-30, 1.5 V 1866MHz, the other two are Corsair Vengence 9-10-9-27 1.5V, 1866Mhz.
The program "CPU-Z" shows CPU = Gigabyte AMD FX-6300 six-core processor, socket AM3+ (942). The memory pane in CPU-Z shows DDR3, channels = dual, size =32gb, DRAM frequency 669.6MHz, FSBRAM 3:10, CAS Latency = 9.0 clocks, RAS# to CAS delay = 9 clocks, RAS# precharge = 9 clocks, Cycle time 24 clocks, Bank Cycle time - 33 clocks. The SPD panel on CPU-Z shows slot 1 max bandwidth = PC3-10700 (667MHz) G.Skill and frequency jedec#5 = 666Mhz, jedec#6=666MHz, xmp-1866 = 933Mhz and xmp-1866 = 933MHz. Slot 2 is the same as 1. Slot 3 shows Corsair jedec #2 frequency = 457MHz, jedec#3 = 609MHz, jedec #4 = 666Mhz and xmp-932MHz. Slot 4 is the same as 3.
What I'm trying to achieve is having all four operating at their best speed even though their sub-clock frequencies are not the same. I went into my BIOS and tried to use the XMP settings on profile 1. This did not work and I had a failed boot so I selected to reset all setting to optimum. This is where I am now. I know just enough of this to get myself into trouble without some further advice and directions.
