It's a buffer it basically makes the DIE spread heat instead of being concentrated thus the name Integrated heat spreader.Originally Posted by BeepBeep2
What? I've spent at least 30 minutes with this CPU doing valids and 1M @ 1.6v in normal ambients (even idling around 40c at times), and up to 1.63v in the cold...
I don't really understand how the (lack of) IHS makes the chip die so quickly???
Remove that buffer and the chip becomes far less tolerant to voltage and can spike easily.
For reference I tested this from stock volts to 1.6 where it was finally enough to spike the chip and kill it.
My intention was to kill it and also find out at what voltage for personal data.
If it can spike and kill instantly at 1.6 it can surely degrade with the buffer.
Usually voltage above 1.55 is enough to peg the chips at 55C anyway which is the overall average temp that most chips stability breaks down under high clocks @ normal ambients.
Actually compiling some interesting ln2 data as well but the data is not complete yet.
