hi

sabertooth x79 + i7 3820 + 4x8gb vengenance 1866 + hyper 212 evo + xfx 850 bronze + haf 912 + ocz vertex plus

set multiplier to 40x (4 Ghz) turbo core ENABLED e hyper threading ENABLE
temp. max 65 ° vcore in full is 1.224 v

run linx (3 cicle witouth error)

this procio to 4Ghz with this temp. so for 10 hours a day (in full 3 hours) . how many years can I work?

thanks at all

Hi

We can't accurately calculate your CPU's lifespan with the information you provided, you'd have to know alot about the CPU's architecture and have a very good understanding of how electro-migration effects a CPU over time, even with all that knowledge you could only give an educated guess.

Anyway, the voltage you're using and the temps under load are well within safe limits so if I had to guess I would say it would last at least 5 years before any serious degradation.

thanks for reply. at what temperature the cpu fries? died?

Try to keep the CPU temp below 72C under maximum load for 24/7 use. The higher the temp the faster the CPU will degrade (die).

CPU's die pretty quickly at about 100C, however your motherboard should shut your PC down if it gets too hot (you can set this thermal shutdown limit manually in the BIOS if you want).

is a normal difference 5° between hottest core and fresher core?
sorry for my english

Yes a difference of 5C between the coldest and hottest core is perfectly normal and very common.

Your link doesn't work for me, but the Tcase temp refers to the temperature of the IHS (Integrated Heat Spreader) which is the silver part of the CPU where the CPU cooler makes contact.

Core temps are more important to monitor.
