Gigabyte GA-790FXTA-UD5 & GSKILL 8 GB (4x2GB) DDR3 F3-10666CL8D-4GBHK

Hello, I have.....

Memory: 2 sets of the GSkill F3-10666CL8D-4GBHK DDR3 10666MHz ram (4x2GB sticks)
Motherboard: Gigabyte GA-790FXTA-UD5 AMD AM3
CPU: AMD Phenom II X4 965BE C3

.....I'm getting timing of 9's across the board, but they're rated at 8. What should I put my settings (and voltage) at to achieve 8's for all four sticks?

Simply enter the settings on the memory and/or memory packaging into the BIOS.

DRAM Frequency - DDR3-1333
DRAM Timings - tCL 8 - tRCD 8 - tRP 8 - tRAS 24 - Command Rate 2
DRAM Voltage - 1.50V

Once that is complete, everything should run just fine. If you encounter slight instability, raise NB Voltage to 1.30V and that should help.

Thank you

My motherboard can run these in 1600 mode with a x8.00 Memory Multiplier. Here are the auto settings the sticks turn into:

11-11-11-29-2T

TwTr Command Delay 6T
Trfc0 for DIMM1 110ns
Trfc0 for DIMM2 110ns
Trfc0 for DIMM3 110ns
Trfc0 for DIMM4 110ns
Write Recovery Time 12T
Precharge Time 6T
Row Cycle Time 40T
RAS to RAS Delay 4T

Unfortunately, the system is now very sluggish. What settings do you suggest? Also, what voltage would you recommend? Much appreciated!

Put these numbers in 8-8-8-21T-2T-5T
Trfc 0 Thru 3=160ns
DDr voltage =1.65
SB/HT voltage=1.40
memory clock=x6.66=1333mhz
EC firmware selection =Hybrid
rest at auto

Sorry, I should've been more clear in my last post. I'd like to overclock these to 1600. Those timings are what the motherboard automatically comes up with, but what would be proper timings for the 1600 speed?

[GSKILL TECH]

You can try 9-9-9-27. It may also need more DRAM voltage such as 1.65V.
