My motherboard is a Gigabyte 990FXA-UD3 V4.0 equipped with four RAM slots. All four RAM modules are functioning properly, providing a total of 32gb of memory. Two of the RAM cards are G.Skill RipJaws 10-11-10-30, operating at 1.5V and 1866MHz, while the other two are Corsair Vengence 9-10-9-27, also at 1.5V and 1866MHz.
According to the "CPU-Z" program, the CPU is a Gigabyte AMD FX-6300 six-core processor using AM3+ socket (942). The memory information in CPU-Z displays DDR3, with dual channels, a size of 32gb, a DRAM frequency of 669.6MHz, and a FSB.
RAM 3:10 features a CAS latency of 9.0 clocks, RAS# to CAS delay of 9 clocks, RAS# precharge of 9 clocks, a cycle time of 24 clocks, and a bank cycle time of 33 clocks. The SPD panel in CPU-Z indicates slot 1 has a maximum bandwidth of PC3-10700 at 667MHz from G.Skill, with frequency JEDEC #5 set to 666Mhz, JEDEC #6 at 666MHz, XMP-1866 at 933Mhz, and XMP-1866 at 933Mhz. Slot 2 matches slot 1, slot 3 shows Corsair JEDEC #2 frequency at 457MHz, JEDEC #3 at 609MHz, JEDEC #4 at 666Mhz, and XMP-932MHz, while slot 4 is identical to slot 3.
My goal is to ensure all four RAM modules operate at their optimal speed, even with differing sub-clock frequencies. I accessed my BIOS and attempted to apply XMP settings on profile 1, but the process failed resulting in a boot failure. I then reset all settings to their default optimal values. This situation requires careful handling to avoid complications.
Mixing RAM kits isn't advised. Your memory speed is limited to 1340MHz because of the mix. You should get a 4 stick kit with 4x8GB to support 32GB in your system. Only if you often use more than 16GB would adding 32GB make sense.
Are your current 32GB stable? Did you run Memtest86 and confirm?
