Ideal BIOS settings for F3-12800CL7D-4GBRH with GA-P55-UD3R?

[flea099]

I think I read somewhere that this RAM might not be compatible with this board.

Thanks!

Haven't heard anything about that, th eRipJaws are designed for the P55 chipset

It surely is compatible. Here are the BIOS settings should you need them:

Advanced CPU Features:
CPU Clock Ratio ................................ [18x] or increase for slight OC
Intel(R) Turbo Boost Tech .................. [Disabled]
CPU Cores Enabled ............................ [All]
CPU Multi Threading .......................... [Enabled]
C3/C6/C7 State Support ................... [Auto]
CPU Enhanced Halt (C1E) ................... [Auto]
C3/C6/C7 State Support .................... [Auto]
CPU Thermal Monitor ......................... [Auto]
CPU EIST Function ............................ [Disabled]
Virtualization Technology ................... [Disabled]
Bi-Directional PROCHOT ..................... [Auto]


Uncore & QPI Features:
QPI Clock Ratio ...........................................AUTO
QPI Link Speed .............................. AUTO
Uncore Clock Ratio...........................AUTO
Uncore Frequency .......................... AUTO
Isonchronous Frequency ..................[Enabled]


Standard Clock Control:
Base Clock (BCLK) Control ................ [Enabled]
BCLK Frequency (MHz) ..................... 160
PCI Express Frequency (MHz) ........... [100]

C.I.A.2 [Disabled]

Advanced Clock Control:
CPU Clock Drive ..............................[800mV]
PCI Express Clock Drive ................... [900mV]
CPU Clock Skew ............................. [0ps]


Advanced DRAM Features:
Extreme Memory Profile (X.M.P) ......... [Disabled]
System Memory Multiplier (SPD) ........ [10.0]
Performance Enhance ...................... [Standard]
DRAM Timing Selectable (SPD) .......... [Expert]

Channel A + B + C

Channel A Timing Settings:
##Channel A Standard Timing Control##
CAS Latency Time ...................... 7
tRCD ....................................... 7
tRP ......................................... 7
tRAS ....................................... 24

##Channel A Advanced Timing Control##
Command Rate (CMD) ................ 2

Advanced Voltage Control:

CPU
Load Line Calibration ................. [Disabled]
CPU Vcore ............................... 1.275 [1.2750V]
QPI/VTT Voltage 1.150v ............ 1.100V [1.190V]
CPU PLL 1.800v ....................... 1.800v [1.800V]

DRAM
DRAM Voltage 1.500v .............. 1.650V

Thanks so much. Just built the new system and configured the BIOS to you recommendation. However, my BIOS only allows changing dram voltage by increments of .20, so my options for this setting are 1.40v and 1.60v. Which would you recommend?

Thanks again.

[GSKILL TECH]

You mean increments of .02V? That would mean 1.64V for DRAM Voltage.

Thank you

Hello,

I have the same config,

increment are 0.2 v: 1.4V-1.6V-1.8V

I noticed that you mention

CPU Clock Ratio ................................ [18x]

The CPU ration is defined by you re CPU? i got a I5 750 and it mention 16X
if i dont want to OC it i guess i should let it at 16X

or am i wrong??

Thank you

SELLIG,

It depends on your memory as well since you only have a max memory multiplier of 10X.

Stock CPU is 133 x 20 = 2.66GHz

If you have DDR3-1600 memory, CPU multiplier would need to be 160 x 16 for 2.56Ghz or x 17 for 2.72Ghz

The reason why BCLK needs to be 160 is because the memory multiplier max is 10X, so in order to get DDR3-1600, it needs to be 160 x 10 for 1600.

Thank you
