Before i start, This is the system:
CPU : Athlon II X4 750k @ 4Ghz , 1.38v - 4month old
GPU : Sapphire 7870XT [Tahiti LE] @1150\1550 , 1.238v 2 weeks old
RAM :1x Kingston HyperX blu 1600mhz 4GB @ 1866mhz 1.6v, NB is at 2100mhz 2 weeks old
MB : Gigabyte GA-A88X-DS3 4 month old
PSU : Seasonic 620W S12II-620 3yr old
Case : Coolermaster CM 690 II 3 yr old
CPU Cooler : Corsair A70 3yr old
Now to the "fun part".
The cpu keeps on throtteling [1-2 cores at a time] temp sensor shows package temps at 90 during load, even tough i got an aftermarket cooler, so i can't really overclock it because the throtteling makes the performence even worse than before.
During gaming CPU and GPU performance rarely reach 90-100%
they usually bounce between 50-70% . [BF3, Witcher 2] , i often even get fps drops in non demanding games such as dota 2.
3dmark's fire strike seems to work fine : http://www.3dmark.com/fs/2348873. but since its stressing the system for only a few minutes , the cpu does not throttle.
Things i tried:
Formatting the pc reinstalling all drivers.
All power saving settings in the bios are disabled .
Reinstalling the cpu reapplying thermal paste Arctic silver MX2 [got it with the cpu cooler and they both served me perfectly fine with my older i3 540 @ 4.3ghz never exceeding 60c.
my thoghts:
Bad temps sensor on \ cpu \ mb [the cpu temp in the bios seems to be ok with 40c its just that "package temp" that i see on hwmonitor thats really high. tried using coretemp , speed fan.
none of the show a cpu temp. even though there is a tmpin0 in hwmonitor that i suspect is the cpu temp, never gets too hot so i assume its that package temp that throttles.
the throttling causes my cpu to never run at full speed which bottlenecks my gpu .
any opinions and ideas?
Thanks.
