Core2Duo volt issue

[dVeLoPe]

I have been trying to get past the 3600mhz overclock mark and can do 401-403 but 404-405 fail.. this is with the volt set to 1.55 but vdrop makes it 1.536... Anything higher and pc shuts itself off if I try to give it more volts. I have seen other water cooled e6600 hit way over 1.65-1.7v whats wrong with mines.. Am i supposed to overvolt the vMCH and FSB to?

Its more down to your cooling and luck.
If a spot temp gets high enough inside an IC, the silicon wont function as required.
Not all silicon is the same so you can expect differences.
Better cooling can bring the spot temps down to a working temperature.

Dude im at 30c idle and with the vCore at low 1.44 load 40ish C.. With monster 1.55vCore im at 51-57c... It's not temps as I have a 350$ water cooling setup..

57C for watercooling is high enough to cause problems.
Spot temps inside the core will be much higher when that temp is with water cooling rather than with air.
Idle temps dont matter here.

I dont have a C2D to test with, I hope someone else chimes in that does.
Find out how high the motherboard will clock, maybe your motherboard/memory is the issue?

Memory is XMS2C4 4/4/4/12@400 so it's only a mean 5-10mhz overclock.. Tests fine at 3.6 and that temp was high because a/c is shut down and ambient was about 28c... Has to be something that im not doing right.. Maybe up the vFSB or vMCH or raise timings..

57 degree is normal because i have a 300 dollar watercooling setup also, and it is idel @ 40 and loaded @ 50 with 1.55v.

You have 50C temps, he has 57C so I'm not sure why you told us that.
How does having a $300 water cooler make 57C ok?

Because Core2DUO OVERVOLTED run REALLY hot... I can get it to about 3.5@1.49 stable with only load temp of 48c tops... or 3.4@1.44 and not go past 45c....
