Model of the motherboard: Gigabyte GA-890FXA-UD5 Rev 2.0 Bios F6
Model of the memory: F3-10666CL7D-8GBRH
Model of the CPU: AMD Phenom II X6 1055T
The problem I'm having is that, while my old pair of 2x2GB memory rated at 1600MHz with 1.65v at 7-9-7-24 runs fine, these don't seem to want to run at 7-7-7-21 with any combination of voltage or slots that I've tried so far.
At first, I figured something doesn't like my ram running at a CL of 7 but I confirmed that my older pair worked just fine (even booted with 1.5v - which these are supposed to do). I even tried a looser CL of 8 (8-8-8 at 1T and 2T) but with the same outcome. What happens is that, I set the timings in the BIOS and when I reboot, I get the warning that my previous overclock was unstable and thus would be reverted to the previously known good configuration. When I check the memory settings in the BIOS, they are the same as to what I just changed them to so I'm unsure about what its actually changing back.
I have tried each stick individually and the same issue persists in all slots on my motherboard. I've run Memtest86+ for around 8 hours with no errors with both sticks in while running at the loose timings of CL 9 at 1333MHz.
At this point, I'm thinking that my 1055T's IMC simply cannot cope with the density of these modules even though I have raised the CPU NB Volts along with upping my memory to 1.65v using the provided steps in the BIOS.
I am probably missing something and I'm looking for some advice. Thanks.
