What values should be changed and what are 'safe' changes in voltages ?
QPI clock ratio X36
Uncore clock ratio X18
Uncore frequency 3600 MHz (should be atleast 1,5 times memory frequency on gulftown?)
Bclock 200 Mhz
system memory multiplier (SPD) 10
Memory frequency 2000
PCI express freq 100 (Did see somewhere that someone recommended to set this to 101 instead of 100 any benifit?)
Loadline calibration level 2
Cpu Vcore 1.3V
xDynamic Vcore(DVID) disabled
QPI/VTT voltage 1.3V
CPU PLL default
PCIE default
QPI PLL default
IOH core 1.14 V (2 graphic cards, or should one look at count of gpu cores ? 2 on each card?)
ICH I/O default
ICH core default
Dram voltage 1.66V
settings on ram are 8 8 8 24
tried overclock cpu to 4,3 GHz but failed.
tried put up Vcore and Vtt but no success. Any other tweaks one must do ?
currently running cpu at 4 GHz with Vcore 1.250 V and Vtt 1.2V bclock 200, ram 2000 MHz timings 8 8 8 24.
any tweaks in bios that would help me get last 20 MHz on core to make gpu cards run stable at core 1000/mem 1200 ?
