Downclocking issue.

Hi to everyone.
I am having issue's where my system hits 62c and it drops the cpu down to
half speed under prim95 and occt this is all at stock setting with no overclocking applied.
Under prim95 and occt it craps out at around three and a half minutes in to the test.
Also I have a i5 760 that will do the exactly same.
My system is.

Intel core i7 870
Asus P7h55-M
Corsair 8gigs ram
Asus 660ti.

Things I have done to try to stop it are reset the bios flashed the bios from asus with the most up to date bios which was the same one that was on the motherboard already.
thnx

Normally gets up to around 55c to 60c with around a couple of hours game play.
I don't think it has down clocked it self as I would have thought frame rates would have tanked to a unplayable rate
while gaming.
30c while idle.

The cpu is not overclocked its doing this at stock speeds 2.93GHz then 3.2GHz boost thing
hits 62c in prime and then throttles the cpu just dint think that was normal for stock settings at 62c to throttle its self down.
But thanks for your help.

Every thing is working as it should with the pump that's at full speed witch shows running at 4440rpm also swopped out the cooler and put the stock intel heatsink and fan back on it.
Same results always 62c downclocks its self using with Asus pc probe2 the temps only get's to 45c real temp is showing 62c.

tested with other stress programs?

intel burn test?

think prime does have a rest peried for few seconds till the next worker stress,its not temps it should go above 100c before it throttles

Ok I will give that a go and report back.

Well that made it throttle even faster.

try latest cpu-z

ftp://ftp.cpuid.com/cpu-z/cpu-z_1.70-setup-en.exe

your cpu usage is still showing 100%

Using the cpu-z v.1.7 gave the same results.
I understand that the cpu is at 100% usage but it has throttled down to around 1.4GHz at witch point the cpu temps drop down to around the mid 40C range so the cpu is definitely throttling its self down.

Here is a video in real time to show what's going on

is there an anti surge option in the bios? tried without that enabled?

I have that board but with an i3 540 and it doesn't throttle like that

Just tried it with the anti surge option set to off had the same results still throttles it self down.
Beginning to think there is a issue with the motherboard as it yields the same results when I swop the cpu out for the i5 760 cpu.
Thnx

Sorry for the delay I put it in to the shop see if they could work out what's
going on with it they tested the psu motherboard other cpu's psu is fine
they used there own to be sure did the same thing they said It could be the mobo
but not 100% the cpu's where tested both checked out fine so I'am going to get a new mobo and be done with it.
Thnx to all That posted trying to get to the bottom of the issue.
