I changed MCH core to 1.200,ICH core is still at 1.505,RAM is still at 800mhz as its rated at 1.8 volts,I dont think I should overclock or tighten its timing,right?
with OCCT Linpack I get 59 celcius.
Another thing,since its taking a maximum of 1.264 volts.should I lower the cpu vcore in the bios to something like 1.27v?(right now its at 1.3 because I read that cpu z might not give the correct vcore reading.
on LGA775, i have never touched anything MCH or ICH core, also, you can underclock your RAM from 800 to 666 to get a 1:1 ratio going with your CPU. As for the VCore, keep it as is, you should be fine if set to 1.300, just make sure the temps do not get too high...
Is 1:1 still better than that "asynchronous" thing,and you mean I should set the MCH core to its default voltage because in the OC guide,he said to set to 1.200v is you have two sticks of RAM(don't know if this is just his opinion or a must)
