X9100 stable but hot

There are a couple of similar threads, but I want to get an idea of what temps you guys are getting with your X9100 at 3.53Ghz, specifically in an NP5796 or 5797.

I'm hitting 95C after a couple of minutes of Orthos, and then RMClock starts throttling me back to 85% periodically to keep the temperature there. Is this a normal full load temperature? I installed the X9100 myself and although it's my first time to change out a notebook CPU, I've done it a thousand times on desktops, and I made sure to do a good job with the thermal paste, made sure the heat sink had solid contact, etc.

It's rock solid so far undervolted to 1.2V at the 13x multiplier... it's just hot as hell. Surely this can't be a safe full load temperature?

 

try running it with the cover off and lifted about 1/2 inch off the desk in the back...see if the temps even budge. also listen to see if you hear the fans going full speed and that all fans are in fact running...

 

I get very similar temps to you Skythian (at least if you mean on the the THM0 sensor) and I'm not even overclocked. Fans are all working fine and my laptop is raised off my work surface by a couple of wine corks.

A while ago I even had a couple of surprise shutdowns which I suspect were overheats - once while encoding video and once while gaming. Those were VERY worrying, but I'm not seeing any signs of permanent damage.

Since then I have it undervolted to 1.1V. Orthos still pushes it past 90C, but now GTA4 tends to only push it to high 80's. I think this chip just runs extremely hot. I've seen another thread where someone had CPU overheats (and shutdowns) in Crysis with the X9100.

 

i will agree with you there.. chip runs hot...now if you run it at it's designed specs..does it still get crazy temps?

 

Like I said (I edited), I'm not overclocked. In fact due to RMClock not being able to use half multipliers I'm slightly underclocked.

 

same problem E wrecked ran into with the gateway 7811. he had to down clock by .05 just to keep that thm0 sensor in check. and that is coded in the bios.(thmo)

 

Thanks for the responses guys. I think you're right Laivasse, the more I read about this chip, it just seems to run hot. Gaming doesn't push it nearly as hard for me, thankfully, I'm only getting in the 50s and low 60s after an hour in Crysis Warhead, but Orthos bakes it.

I may work on undervolting a little farther, and see if I can maintain the 3.5Ghz. I'm used to desktops, where there's always room to add a bigger, better heatsink, but options are more limited in a laptop.

 

Incidentally, I presume you're using a notebook cooler? I just want to account for why I'm getting the same temps at stock as you're getting at higher voltages and speeds...

 

95C at stock?
Woaaa, you`re in desperate need of undervolting asap.
75+C for the CPU is kinda dangerous.

 

Well, I'm undervolted actually, to 1.2v (and now that I'm thinking about it, I'm going to lower it and see how stable I still am).

I do not use a notebook cooler and actually just started turning the fans to full speed while I'm playing games with Fn+1. That helped quite a bit, but like I said, I haven't had much of a problem with heat anyway while playing games. It's just Orthos that kills me.

 

So far the highest temp I have had is 95C on the ACPI while playing Crysis for long periods of time 2.5+ hours. If I only play like an hour I usually will only get into the low 80's. How do I undervolt the CPU? Will I still be able to use very high graphics in Crysis?

 

I have the M860TU and am running stock clocks on my X9100 and have never gone above 83 C with Orthos. Undervolted I never exceed 63 C.
I run 1.0v on all multipliers but the max multiplier I at 1.0250v. Of course it downclocks slightly to 2.96ghz but thats hardly any loss of performance when you compare the 20 C cooler it runs.
Now if only I can OC my X9100 in my M860TU

 

Can you explain how you might be getting such lower temps than me? I have not run Orthos yet. Is it free?

 

I believe orthos is free. Run it for a good 15 min to get a good judgement.
I'm not totally sure why I'd be running cooler.
I have thermal paste on my CPU and GPU. Maybe my SSD keeps the temps of the case a bit cooler. I ripped out all of that crappy black tape that was covering my vents.

I usually do my testing on a flat table with nothing around or behind it. And my room temp is between 19-20 C which can make a difference (chilly in Alberta sometimes).

 

I will have to grab some tools from work and see if I have vent tape over my fans. Any tips on removing it?

Also I still was curious if anyone could give me some direction on undervolting the CPU.

 

Just rip the tape off but brace the cover so you don't break it. The tape is thick and on there pretty good. While you have it open check for a buildup of dust and crap on your heatsink and fans, then blow it off with compressed air.

Just follow the undervolting guide. I never had any previous experience with undervolting nor did I even know what undervolting was until I read that guide. It's a great tool.

 

What VID's did you use in your Profile for 6.0x thru 11.0x?

 

1.0v for 6-10
1.0250v for 11
I tried unlocking the smaller voltages tweak but even with less than 1.0v selected it would not take effect.

 

Wow this has helped out a lot scourge18a!

I got up to 96C with ORTHOS before modification and now with all VID's at 1.0500V I am only getting up to 77C after 15minutes and it doesn't look like it will go much higher since it lowers after hitting that temp for about 30 seconds.

How did you unlock 1.0000V? 1.0500V is my lowest. I am using version 2.35.0 of RM Clock.

I wouldn't mind setting my voltage lower like you did but I am so happy with the results so far! I was very worried about doing damage to my CPU before, its like a large weight has been lifted of my chest.

 

No problem.
In your RMClock folder right click the rmclock_tweaks and click edit. scroll down to "unlock full cpu voltages" and change the 00000000 to 00000001 and you will have other voltage numbers available.
Even though I changed my voltages to lower than 1.0v CPU-Z showed that 1.0v was the lowest value obtained. Maybe you will have luck with it though. If you do let me know as I am sure the lower multipliers could go lower.

 

this all depends on which version of cpu-z you use....

it seems that for mobile platforms it's better to use the older version of the software to get an almost direct voltage reading. something like 1.41 or 1.42 if im not mistaken. we ran into this problem when doing the under volting of cpus. the older version will read .0925 to .0975 where as the newer versions stay around 1.0v. not sure about the very latest version of cpu-z.

 

Ya I used the older version.
It was reading correct for evey other value I submitted but the lower voltages just didn't take for me. Maybe I didn't screw around with it enough though. I can always give it another go, cuz I would sure love longer battery life.

 

1.41 doesn't seem to like win7...

 

i notice that a few of my programs dont want to pop up from the bottom right tool bar if i try to double click them...hope this gets fixed quick.
