Need correct bios settings

[oniburn]

I have a Gigabyte GA-P55A-UD4P motherboard with an Intel i5-750 Lynnfield and F3-160000CL9D-4GBTD memory. What would be the correct bios settings for this memory? I can only get it to run stable at 1333 mhz. I tried settings from other posts and my pc will only run stable for 5-10 minutes and it will reboot and I have to set the bios settings back to 1333 mhz.

Try enabling the XMP Profile to see if that will work.

If not, try the following:

Advanced CPU Features:
CPU Clock Ratio ................................ [14x]
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) ..................... 200
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:

Channel A + B + C

Channel A Timing Settings:
##Channel A Standard Timing Control##
CAS Latency Time ...................... 9
tRCD ....................................... 9
tRP ......................................... 9
tRAS ....................................... 27

##Channel A Advanced Timing Control##

QPI/VTT Voltage 1.150v ............ 1.100V [1.350V]

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

Keep me posted on the results.

Under Advanced CPU Features I do not have anything that says "CPU Multithreading" and under the "Uncore & QPI Features I am unable to access the QPI Link Speed, Uncore Clock Ratio and the Uncore Frequency. Any ideas why that is happening?

May simply be a slightly different BIOS revision, but you should not need to make any changes to those anyway.

Thank you

My computer will not boot when I try the settings. It goes into an endless reboot. My BIOS revision is
F8. It will run for a little while if I set the SPD to 8.0 with the BCLK at 200 mhz, but after 15 or so minutes it will suddenly just shutdown.

Increase the QPI/VTT Voltage 1.150v ............ 1.100V [1.400V]

I increased the qpt voltage like you suggested. It ran stable for maybe 5 minutes then it just rebooted. Any other settings I should look at?

[GSKILL TECH]

Have you tried memtesting each module to insure neither is defective? Testing them individually can help sort any bad ones out.

Considering it is rebooting, it may simply need more voltage, so you can try raising the QPI/VTT Voltage further to see if that will help.
