Stress Testing: Post Your REAL Temperature Challenge

[andz]

---

Touche'!

This is my thread so I make the last statement

Quick tests 1-2 hours with OCCT after that, paranoia-mode with a 6-hour run or more with Prime95 on Small/Large FFTs (this draws out maximum heat). For stability testing that includes the memory controller and the memory itself, that would have to be a blend test, run it for another several hours. But between the 2 programs, its the Burn Test Utility that draws the maximum temperature at the smallest amount of time, so try that as well as a quick test. Syaro di pa jud makit-an ang error/max temps.

Now, back to you Andz...post your screenshot na! IBT or Prime95

bati kaau ako oi ma ulaw ko post.
OCCT actually has Small/Medium/Large sets if you didn't know.

Yes, IBT pina ka hot hot hot~

nyak! maulaw na nuon sa ka high-end sa rig. we're just here to show our temps, accuracy be damned .

as for Stress Testing tools, i have SuperPi, Prime95 (64-bit), latest build of OCCT, Intel Burn Test and Orthos. I use OCCT to detect if the instability is caused by vdroop because of the graph but since LLC gives a continous and consistent voltage, wala na kaayo nagamit.

wa jud ni mo-#PROCHOT, glide as per RealTemp? 85c naman ni gud, basin naa pa jud ma tilok ani kay wa man jud throttle.

Poldo- taas2x na gyud ni, not sure why it has'nt throttled yet. Kadyot ra man pud ni hinuon, just to see what sort of temps i get.

Could there be a possibility na ang temp sensors on the die itself is'nt registering the right temps?? i know (or heard of ) this na ang sensors sa intel as of late, naay mga issues daw.

Possible na naa pa gyud ni ma tilok. I also notice that my chipset and mosfets get very hot while running prime at these clocks. Will see if i can get it to run at lower vcore and prime at least 3hrs. Soon hopefully.

^ only 1 way to find out. crank it up some more! exhilarating baya ang experience when you see #PROCHOT. curious lang jud kaayo so i pushed mine real hard just to see what happens when the processor goes on #PROCHOT status, i would've gone for #THERMTRIP pero hadlok nako kay wala raba budget for a new processor.

as for issues with the sensors, i'm not aware nga naa diay problem ang Intel ani. can you post some links so I can read further?

hahaha - kuyawan ko to be honest i think 90deg is when the i7 procie starts to throttle, so 5 more deg and i would have seen that #PROCHOT message you talk about- wala pa ko kita ana, basig karon May 23

Will have to hunt for that link bout the sensors - post lang nya nako

poldo - ni try na ka LinX - luhod sad ang cpu ug ram ani

Finally, I was able to bring down max temp below 80 deg but had to strap the Delta screamers. DK and Thunderblade just doesn't cut it below 80 mark. This is how far I can push it at the current cooling set up. Next would be to lap the cooler and get a very good thermal compound and prolly strap in 2 Deltas and give 4.3-4.4 a shot if possible tempwise.

bai poldo:

PROCHOT#
the system bus signal PROCHOT# will go active when the processor temperature of either core exceeds its maximum operating temperature. this indicates the Thermal Control Circuit (TCC) has been activated. the temperature at which the PROCHOT# signal goes active is individually calibrated during manufacturing. once configured, the processor temperature at which the PROCHOT# signal is asserted is not re-configurable.to make things even worse, this temperature ist not readable in any register, thus is not accessible by any software!


THERMTRIP#
the processor will automatically shut down when the silicon temperature has reached its operating limit. at this point the system bus signal THERMTRIP# goes active and power must be removed from the processor. the temperature where the THERMTRIP# signal goes active is individually calibrated during manufacturing. once configured, the temperature at which the THERMTRIP# signal is asserted is neither re-configurable nor accessible to the system.


Digital Thermal Sensor
the Digital Thermal Sensor (DTS) is the on-die sensor to be used for fan speed control (FSC). each core has its own DTS. the DTS is monitoring the same sensor that activates the TCC. readings from the DTS are relative to the activation of the TCC. the DTS value where TCC activation occurs is 0 (zero).

taken from Intel datasheet for QX9650:

"As an output, PROCHOT# (Processor Hot) will go active when the
processor temperature monitoring sensor detects that the
processor has reached its maximum safe operating temperature.
This indicates that the processor Thermal Control Circuit (TCC)
has been activated, if enabled. As an input, assertion of
PROCHOT# by the system will activate the TCC, if enabled. The
TCC will remain active until the system de-asserts PROCHOT#.
See Section 5.2.4 for more details."

This maximum safe operating temperature is Tcasemax, which is 64.5C on the QX9650. So throttling *CAN* occur right after this. The question is what temp will the DTS inside the core be reading at this point...

And: to prove that throttling does NOT occur at 5C before CPU shutdown:

"In the event of a catastrophic cooling failure, the processor will
automatically shut down when the silicon has reached a
temperature approximately 20 °C above the maximum TC.
Assertion of THERMTRIP# (Thermal Trip) indicates the processor
junction temperature has reached a level beyond where
permanent silicon damage may occur. Upon assertion of
THERMTRIP#, the processor will shut off its internal clocks (thus,
halting program execution) in an attempt to reduce the processor
junction temperature. To protect the processor, its core voltage
(VCC) must be removed following the assertion of THERMTRIP#.
Driving of the THERMTRIP# signal is enabled within 10 μs of the
assertion of PWRGOOD (provided VTT and VCC are asserted) and is
disabled on de-assertion of PWRGOOD (if VTT or VCC are not valid,
THERMTRIP# may also be disabled). Once activated,
THERMTRIP# remains latched until PWRGOOD, VTT or VCC is deasserted.
While the de-assertion of the PWRGOOD, VTT or VCC
signal will de-assert THERMTRIP#, if the processor’s junction
temperature remains at or above the trip level, THERMTRIP# will
again be asserted within 10 μs of the assertion of PWRGOOD
(provided VTT and VCC are valid)."

@master simoko: mga pila kaha tcasemax sa i7 based on your previous OC encounter with the i7's? 82-85 deg? hehe
