HP Envy 17 SB Throttling test

I updated Prime95 and tried again, making sure to be plugged in. And it worked fine. It reached 91 C after about 10 minutes.

Then I tried unpluging it while running prime, furmark, and throttlestop. And after about 10 seconds, it shut off again....

Anybody tried doing this on batteries? It should not be turning off when being stressed and on batteries.

 

The battery can't supply enough power to run. Does it shut off automatically when you run without throttlestop?

 

Sure does.....

 

I don't recommend stress testing with Prime95 + Furmark and then pulling the plug with or without ThrottleStop running. That's a huge load and many laptops come with batteries that are not capable of supplying enough juice to the laptop when the CPU and GPU are fully loaded like that. Something has to give and it's usually the battery. If you are also running ThrottleStop trying to force the built in throttling off, you can permanently damage your battery or shorten its expected life.

 

I was in another thread on DV6/7...and it just hit me.

I could never get Furmark to work on my DV6....could it be because I was trying to run it at 1600*900?

When I get home...I will try it at 1366*768...will that give me an accurate result?

 

Following instrustions FTW...
Yeah...I forgot to uncheck fullscreen way back when...and becaue of that, I didn't get the display error.

With that said, I was finally able to get Furmark to work with Prime95. I bounced between 1695 and 1798. DV6 did not throttle.

 

What CPU do you have? If it's a 2630QM and it is running at less than 2000 MHz then that's throttling. Run and post a RealTemp log file if you would like me to have a look.

RealTemp 3.67

unclewebb, I'll do that tonight.

Yup, I have a 2630.....but I guess it isn't dropping town to 800 MHz....which is kinda good I guess.

 

You made sure to use the AMD GPU right? It also might take a little while for throttling to occur. How long did you give it?

 

Intel® Core™ i7-2630QM Processor (6M Cache, 2.00 GHz)with SPEC Code(s)SR02Y

The 2630QM is rated to run at a minimum of 2.00 GHz when they are loaded and during most games, Turbo Boost is designed to automatically overclock them up closer to 2.60 GHz. Anything less is usually a sign of throttling. It will be interesting to see a RealTemp log while you're gaming.

 

Yup...the gen 5xxx DV6/7's don't have switchable graphics....so I was on the 6570 GPU.

I let it run for about almost 800 seconds....so a little over 10 minutes.

 

Try running it a little longer, I had like 20 minutes without throttling and then it did some drops and it could be fine for like 15 minutes again and then go down. But of course I didn't try it with those programs on the first page, but anyways

 

Updated Coolsense to 2.0 and did more testing. Throttlestop did not seem to help no matter what I did. But when turning Coolsense off, it seems to no longer throttle....... Need to test more.....

 

Wait, could coolsense be the problem? :O And where did you get update for it?

 

It was available for one of the many envy 17 CTO downloads. Sorry too many to remember which one.

And Furmark and Prime run on battery now....

 

Ah okay But could coolsense be a throttle problem? Or did I get your other post wrong

 

Hmmm....down to 1100MHz at times....
Temp is up to 97c according to Furmark...

Time to shut it down for a bit.....

 

Not positive, but it seems so.

 

If it is cos of Coolsense the fix could be easy right? Like just uninstalling it, but of course, I don't know what that would do to the temps. Is coolsense running all the time even if I don't actually start the program? Like is it doing it's thing even if I don't start it?

 

I just sent a report to the BBB, hopefully this will get HP's attention.

 

Okay you guys this will likely be the last thread I make regarding the Envy 17 Sandy Bridge:
http://forum.notebookreview.com/hp-...vy-17-sandy-bridge-awaiting-hps-fix-read.html

This thread is regarding the throttling and the HP Fix (once implemented) as well as the consequences of such a fix.

 

Ok, I ran the test for a good 30 minutes. Before running the test, with just CPU-Z, it was at 798.3 MHz.....
With Prime95 and FurMark, it jumped to around 2,400 something to no less than 2,100 something.. Mostly stayed at 2,295MHz.

I am a bit curious as to why on the 2820 it never got to the max turbo rating of 3,400, much less over 3,000. Why is that?

Temps never got higher than 82 c.

Hi Guys

I just got my new Envy 17 3d today and when ever I play serious gaming it just reboots because of overheating. A black screens comes up after rebootting saying that the system was shut down because of high system temperature.

If I run Furmark and CPU stess test together it overheats again and reboots.

My Temps: (See printscreen)
Board: Max: 106 celcius or around 200 F
CPU: Max 90 celcius
GPU: max 98 celcius

Does this happen to anabody else?

Im most likely to return the laptop and get a new one.

Thanks

 

The most disturbing about these data is that your board is hotter than the CPU. I would want to compare with other Envy users, but on my DV7 this never happens -- the mother board is always within a degree of the CPU package temp, indicating that the cooling system is effectively removing heat.

but these temps suggest that the fan is not running well, coolsense has run amok or the cooling system is not up to task.

make sure coolsense is not messing with you, here, i.e. set to performance optimized mode. I can run furmark and prime64 on my DV7 and get CPU core temps similar to yours, but my board temps are way lower than yours.

 

Thanks for your reply

I just find it strange that my computer is at boiling tempatures...

My old computer would never get more 60 degress celcius even when playing. That was a dv6-2155.

And tempatures around 200F is not good for internal compontents

 

right-o. its not unusual for the CPU cores to be where yours are during stress tests. today's processors pack a wollop in terms of power and that means heat -- so should expect short spikes approaching (but barely acheiving) 100c region in the motherboard if the cooling system is working. but if you've checked all that out then I'd say send her back.

good job testing/validating this within the 21 days. otherwise you'll be sending it in for repair and going through a bunch of arduous hocus pocus. a 10 degree difference between CPU package and motherboard is a disaster, in my opinion. i wish more folks would do as you are doing!

The processors themselves are specified by Intel to run at 100c absolute maximum. Ideally the motherboard should be cooler than the CPU package, but at least on my DV7 it appears this is not quite possible.

check out the fan speed and coolsense. if all is well I'd send her back.

I noticed similar results for my 2820: 1795-2295MHz for most of the test, but usually at 1795. Occasional bumps up to 2400-2500. Max temp 85C. Any ideas why it wouldn't go up to 11, er 3400?

Thanks,
