Default and Safe Voltages for overclockers

post #1 of 7
Thread Starter 
I would like to know the default and maximum safe voltages for;

CPU PPL -- default 1.80 safe 1.88
QPI/DRAM -- default 1.2 safe 1.40 -- 1.35 according to intel
IOH -- default 1.2 safe 1.3 according to intel
IOH PCIE -- default 1.5 safe ?? not really needed since you lock pci at 100.
and
ICH default 1.2 safe 1.3 according to intel

i filled in the blanks that i know, i ll be thankful if you can fill in the rest.


also for those who dont know and reading this thread
for CPU -- safe 1.40
DRAM -- safe 1.65-1.66

IOH upto 1.3v
ICH upto 1.3v
QPI PLL upto 1.3v-1.4v
QPI/DRAM or QPI/VTT upto 1.5-1.6 as long as within .5v of Vdram
Vdram upto 1.88 as long as within .5v of qpi/vtt or qpi/dram
CPU vcore 1.45-1.5v with adequate cooling
CPU PLL upto 1.9v
PCI-E upto 1.6v is fine
ICH/IOH 1.5v voltage 1.6v is fine too.

nope you are within .5v of vdram. That is why intel says max VDram of 1.65v because stock qpi/dram is 1.15v, if you go higher you are out of .5v. Same thing for qpi/dram max of 1.35 and then Intel does state Vdram max of 1.85 in the same document. They also talk about the .5v differences, it is mainly due to the fact that the CPU powers a portion of the RAm power.
