i7-2920XM Abnormal temperatures after bios reset

Hey,

If someone read my thread with 880M then he know that I had a problems with these cards and did a BIOS reset just for safe. However after that reset my CPU temperatures are fake. Before the reset it was all fine. CPU was set to 4.0/3.7/3.4 and was running fine. Now i have same configuration and after 2 sec of 32M Prime temperature raised up to 97C(!!!) and 100% throttling was detected by Intel XTU. What's wrong? Im attaching screenshot from ThrottleStop:



That's just not possible. I've heard CPU fan spinning but not on full speed. And all this **** is after resetting BIOS to default values. Have anyone clue what's wrong? I can't do anything because cpu is throttled all the time.



Regards

 

Your fans should be roaring full blast with those temps. They are not?

If you are using HWiNFO64 manual fan controls, that may be messed up. Sometimes the manual fan control will interfere with EC/BIOS communication and cause the fans to stop working correctly. If you are using it, disable it from starting with Windows. Shut down and cold boot and see if the problem goes away. If that is the reason, be sure to disable EC support in the settings and clear you manual fan profile so the system EC controls the fans instead of HWiNFO64. Once the system returns to normal, leave EC support (Dell and Compal EC support) disabled and create new fan profiles if the stock fan tables do not suit your needs.

If you are using Almico SpeedFan, stop using it... it has caused me many problems with fans malfunctioning and HWiNFO64 is far more reliable.

With those low CPU clock speeds, your Flex VID can probably be set to 0 (zero). If you use a standard Level 1, 2 or 3 overclock, that sets the CPU voltage too high. Might check that in the BIOS to make sure it is not set too high. Level 3 is 25 by default and that is way too much voltage for those low clock speeds.

 

HWiNFO64 wasn't loaded with Windows but I've removed it completely, better safe than sorry. I've never used Speedfan. I had Flex 0 but just for test I've raised it for 5.

Do the EC table resets itself with every computer startup or need I to load default in BIOS to restore stock fan table? I've been planning to install fresh Windows in next days, will the issue dissapear on new system without hwinfo?

And one ADVICE from me if anyone is reading this. DONT use HWINFO if you did a BIOS reset.

Also in HWInfo I can control the fan manually but max is about 7000 RPM and AFAIK that's gonna damage the fan. If I go to the HWinfo manual control it always says ACTIVE, I can click System auto then it says INACTIVE but after next program run it again says ACTIVE.

I've set the lower clock and manual fan control. Fan is on full speed (3800 rpm) but temperatures are still weird. However if I look at the CPU sensors then only core 2 and core 3 have weird values. Core 1 and Core 4 has about 77-80C and that's normal. Also I've notified that looking at Compal EC gives temperatures much lower than on these weird cpu sensors. I assume something changed in the bios after reset. Any way to figure out what?

I don't think these values are real. It's just impossible to jump from 55C to 97 in 2 seconds wtf.

 

a bad paste job can do it... too much can act like not having a heat sink at all...

 

Hmm last time I pasted cpu was about 1 year and 2 months ago. I'll try repasting it.

 

Wow, I assumed you did that while it was apart for your 880M installation. My bad for assuming.

Grab some Liquid Ultra and you'll have the best CPU temps you have ever seen.

It is the only thermal paste I will use for CPU any more. Nothing else compares to it.

 

No i forgot about it. I was very upset because of this vbios that bricked my gpus that i forgot. Thanks for the advice but I know how to repaste it properly. I'll use same Zalman-STG2 paste.Im satisfied with gpu temperatures and my max cpu settings will be about 3,5 GHz for 4 cores so I don't need anything superior. I just think that the paste turned into solid rock crap and need to refresh it

Best regards Mr Fox

 

The advice is only for Liquid Ultra. It requires a different process that normal paste. Good luck... I have no doubt it will turn out right. Anyone that can desolder their GPU chip, reprogram it manually and put it back can certainly handle a simple paste job.

 

LOL you say that Mr Fox....


Just joking ... I'm quite sure he will be fine.. Also 3.5GHz is too slow.. You'll bottleneck your 880M SLI.. I would suggest 3.8GHz/4.0GHz at least...

 

Hey,

I don't need that much power. I want to have about 45-60 fps with maximum settings and FXAA. No need to push further than 45 fps because I don't see the difference. Thanks to 8GB VRAM I can use super duper ultra HD textures hehe. I do not often play newest games because I prefer older one like STALKER shadow of chernobyl (10/10 if you ask me), Payday 2, Cuban Missile Crisis,HOMM V. I've installed ACU and Dying Light but they are too "modern" for me. From newest games only Dragon age Inquisiton and Deus ex HR weren't bad. I sometimes play Gothic 2 from 2001 with mods. Russians have very large modding community so best games won't die so fast. It's already a laptop with monstrous power here. Most of my friends have desktops that have GTX 550 Ti and Q6600 so this DTR eats their computers for breakfast

I also like when I play games and my computer is silent and cool. That's what I call power. It can handle most of my games without even turning fan on high rpm. Im very satisfied with this M18xR1 but im sure that's my first and last Alienware because new 2015 line simply sucks. I'll probably replace it after six years or something like that.

 

Ok I've repasted the cpu and cleaned fans ( huh I've nearly collected full cat fur from it). Temperatures are normal now, thanks guys. Didn't know that it can have so much impact.

 

Maybe you can sell the fur to offset the cost of the paste.

 

My cats would kill me then. Im their hostage

 

If you really want to upset them, have them watch this video. They may need counseling after that.

 

HAHAHA Mr Fox!! Cheeky
