Yeah I used to think Intel chips could self-protect, but then I blew a 5660 with 1.4QPI/IMC and a 5650 with 1.45V core...

If I were you I'd get 3.8GHz dialed then optimise the memory and cache.

They just degraded -no longer able to hold the clocks. the 5660 was done-in by VTT overshot, and I pushed the 5650 to 4.6GHz 1.45v and that blew it!

1,45 v vcore / 1,4 v QPI/VTT/IMC is enough to blow these chips, was your temperature also too high or just voltage? To be honest the fist A Batch chip I have somehow it is degraded already a little bit I guess after I did the 1,55 volts test unfortunaley, because after this somehow it need a little higher voltage for the undervoltig tests I did before frown.gif The saved uv BIOS profiles were no stable anymore they crash after 7 Minutes.

All of the above are potentially damaging.

<1.35v <81c are the maximum design values.

Temps and volts both went over.

Effects of ruthless overclocking frown.gif Thank you, you woke me up to be very careful now to avoid that what happened to you smile.gifwink.gif If you are within the specs It is normal you have to give more voltage if you overcklock to be stable with time (degradetion, elecktromigration) or even just if the cpu was always at stock but if it's old. What is your experience?

The answer is water cooling and a good psu smile.gif. I've exceeded max recommend volts on qpi, vtt, and cpu for years on these with oC sessions into ungodly territories lol

I've heard disable cores (like only 1 core is enabled) and hypertheading in BIOS will kill the cpu at least the Core i7 980X. The W36xx and X56xx use the same chips as i7 980X. Is this really true?

I can only say ive not heard that. Maybe they were using one core for max clocks and overvolted it to death?
