Settings for GA770TA-UD3 and F3-12800CL9D-4GBRL

[jnl]

Hi,

My motherboard GA770TA-UD3 runs my new 2x2 Go GSkill F3-12800CL9D-4GBRL at 1333 MHz by default, instead of 1600 MHz.

I set to 1600 (9-9-9-24) manually in bios but got sometimes errors (windows failure, of even bios alerts "overcloked settings" going back to default settings). It might be because I set the Gskill modules to 1T. A very quick pass on memtest under windows led to no error anyway.

- Can you tell me if all the timings you recommend in post #2 here apply to the mb GA770TA-UD3 too ?

- Is 2T necessary for the F3-12800CL9D-4GBRL @ 1600 MHz ?

- I put the 2 memory modules in slot 1 and slot 2 as recommended in the MB manual for dual channel mode operation. Would you recommend any other configuration ?

My system :
Gigabyte GA770TA-UD3
AMD Phenom II X4 955BE (step 3)
2x2 Go DDR3 1600 Rip Jaws (F3-12800CL9D-4GBRL)
480w PSU
Windows XP Pro

Hope you can help. Thanxs.

Try these settings:

ACC EC FIrmware Selection= Normal
ACC = Auto
CPU Clock Ratio = x18
CPU Northbridge Freq = Normal
CPU Host Clock Control = Auto
CPU Freq= 200 MHz
PCIE Clock= Auto
HT Link Freq= Auto
Memory clock = x8.00 = 1600MHz
DCTs Mode = Unganged
CAS#LAtency = 9T
RAS to CAS R/W delay= 9T
Row Precharge TIme = 9T
Minimum RAS Active Time = 24T
1T/2T Command Timing = 2T
TwTr Command Delay = 5T
Trfc0 for Dimm1 = 127.5ns
Trfc2 for Dimm2 = 127.5ns
Trfc1 for Dimm3 = 127.5ns
Trfc3 for Dimm4 = 127.5ns
Write Recovery Time= 12T
Precharge Time= 5T
Row Cycle Time= 40T
RAs to Ras Delay= 4T
CPU NB VID Control= Normal = 1.2V
DRAM voltage control= 1.500v
DDR VTT Voltage Control = 1.100V
NB Voltage Control= Normal = 1.200V
SB/HT Voltage control= Normal = 1.300V
NB PCIE Voltage Control= Normal 1.8V

2T is not necessary as the system will automatically set to that if it can not operate 1T.

Woo what a quick answer ! I'll try and see how it goes. Thank you.

Ps : by "2T necessary" I was wondering if the 12800CL9D-4GBRL can operate @ 1600 and 1T, or if it's 'highly' recommended to put them @ 2T at this frequency.

It simply depends on the system. Some can do 1T, some can not, so if you can run stable at 1T, then simply leave it at that.

Thank you
