Overclocking crash, help please

[Leeroy123]

Hey all, im just a little lost with my overclocking, only just started and im struggling now. I replaced the cpu cooler with http://www.arctic-cooling.com/catalog/product_info.php?cPath=1_42&mID=69 and i replaced the gpu cooler with http://www.arctic-cooling.com/catalog/product_info.php?cPath=2_&mID=103 .Then i thought id try to overclock, i upped the FSB from 333 -360, and lowered the dram freq. Just be doing this alone when i run real temp to check the temp of the cores, its going as high as 85 degrees under stress. And this is only at 360? my case cooling is fine , i have enough air supply in my case and its nice and cool. Im worried about pushing any further than 360 because the temp is reaching that level. I did find a video on youtube showing what someone did to overclock his E8400 3ghz dual chip, which is the same as mine, i did exactly what he said which was change the FSB to 400 and up the voltage to 1.23750, when my pc booted up i got a bluescreen crash, so went into bios and reset it back. Now im lost as to what to do, i know very little about changing the cpu voltages. Not sure what to do next, pretty much lost and worried about pushing it too far to get more crashes. Any advice / help would be appreciated.

I forgot to add temps, my temps now with no overclock in this system are

GPU 44
System 32
CPU 31
AUX 22
HD0 43
HD1 26
CORE 0 46
CORE 1 45

These temps are taken from Speedfan.

Those are pretty high load temps, id check that the cooler is seated properly. Also as your running 8gb of ram youll need to up the NB (north bridge) voltage as filling all ram slots puts extra strain on the NB, also make sure that your ram voltage is set correctly in the bios, some early p5q bios revisions can overvolt ram by quite a bit, my ocz is rated at 2.1 but i set it to 2.02 to compensate for this.

these are high temps? the cooler is defo seated properly mate i only reseated it yesterday actually.Up the north bridge voltage? i dont understand that. ram voltage in the bios im not sure what it is, what should it be set at? my ram voltage will be set on automatic , i have the latest bios too mate. Real temp tells me cores are 40 and 41 and distance to tj max is 58 and 60, what does distance to tj max mean???
