F3-14900CL9-4GBXL timings help

[Bladestone]

Hoping to find some help with timings to get the most out of the memory I have and still keep things stable.

Memory: F3-14900CL9-4GBXL
Motherboard: Asus M4A87TD/USB3
Processor: AMD Phenom II X4 970 (Deneb)



Good cooling in the system and on the processor and I wouldn't mind overclocking a small amount, but don't want to do anything too crazy.

Thanks in advance!

You have them running right about 1600, so I'd try at 8-9-8-28 2T

CPU Host Frequency will need to be 233 for DDR3-1866. That CPU can only support DDR3-1600 max, so overclock settings are necessary for DDR3-1866.

Note, this will also overclock your CPU Frequency, so you should lower CPU Ratio if this is not desired.

CPU-NB Frequency should be 2800MHz, or 12X (233 * 12 = ~2800).

Then set DRAM Timings to tCL 9 - tRCD 10 - tRP 9 - tRAS 28 (that the memory is rated for).

DRAM Voltage 1.50V, this is default, but it should still be manually set.

Lastly, CPU-NB Voltage 1.20V-1.25V. This will help the CPU fully support DDR3-1866 since AMD technically supports 2 modules of DDR3-1600 only.

Keep us posted on the results.

Thank you
