Life of the chip?

post #1 of 5
Thread Starter 
if i raise the FSB and lower the Core Voltage will the life of the chip decrease or increase?

and wat about at stock speeds but lower voltage?

Generally it's a pretty bad idea to under-volt a chip at stock speeds.... even worse of an idea to undervolt the chip AND and clock up the FSB...

Chips are made with a VID for a reason... CPUs are designed to run at stock speeds at an optimal amount of voltage (the VID)... under-volting will most likely lead to instability, especially when overclocking.... your best bet would be to find your maximum overclock with acceptable voltages/temperatures, make sure that it's completely stable, then start lowering the voltages until it's no longer stable...

Although temperatures might be lower on a undervolted/overclocked (or stock) chip, the overclocked/overvolted chip is most definitely going to last longer if the former is unstable...

I guess the keyword in this whole soliloquy is "stability"... if you can undervolt/overclock AND remain stable, the chip will last longer due to lower temperatures - however, most chips will not be capable of running higher speeds with less than optimal juice

but as long as it stable for 24 hours on a stress test then it should be fine right?

Generally speaking yes you're computer could be deemed "stable" although a good 24-hour stress test isn't a 100% determining factor. I was pushing my Q6600 to see where it topped out and while it would pass Prime95 in one instance, there were occasionaly freezes and errors that were remedied by backing the clocks down a little.

it really doeant matter how you configure it, if you stress test long enough it will always error at some point. remember an error is a big diff than a BSOD or shutdown.
24hr is no diff than 12hr on prime and I usually see any error in a 2hr test with occt that i see in prime95 12hr.

the trick to it is to find max stable clock speed with lowest voltage... some may run exact setup as you and get 4.2 w 1.2v while you need 1.3 to get to 4.0, just how it is..

really its the fun part of the whole thing...

I have found my "sweet spot" now at times when i get bored of games and sit there thinking about what i can do to tweak it some more
