please help me!!! i have this problem.
i have this system:
mobo:Asus P5E3 Premium with X48 chipset,
CPU Intel QX9650(batch L744B156)
and memory: Corsair Dominator DDR3 at 1800Mhz.
i don't want to make something extreme with this.
i only want to put the memory to play at 1800mhz. so in bios i put
manual,
multiplier to 7.0,
FSB Strap to Northbridge 400,
FSB at 450,
PCI-E:100,
the memory 1800,
timings : 7,7,7,20,
command rate: 2N
and memory voltage 2.0V
all the memory settings are the stock settings.
all the other settings i leave them to auto.
also the DRAM Static..and DRAM Dynamic...i put them to disabled and load line calibration i checked to both normal and performance and CPU Spread Spectrum and PCIE Spread Spectrum also disabled.
so i have the CPU at 3.15GH and memory at 1800Mhz.
Now the problem is that the system is not stable.
if i run CPU Stability Test after 1-2 minutes says problem in TPrime module. also in Prime95 multicore after a while fails in 2 cores.
please can you advice me what settings may i put to make my system stable?
also i noticed in Real Temp that from cpu the core 1 sensor is stuck at 40c always.only if i overclock to 4Gh the sensor starts to work. in my system i have a watercooling solution from Thermaltake. but the cpu temp is idle at
45c. is it right this temp for this cpu? also if i underclock,the temp stays at
45c.
i think something is wrong here.i have bad luck with my cpu? should i RMA it?

running 0503 bios(also tested 0401,0402)

this is what i get from Cpu Stability test and Real Temp:



thank you!!!
