7811FX new heat issue ACPI TZS0

Being that this is an issue with the amount of power flowing through a closed circuit..if you undervolt the CPU, your TZS0 will still read 98c, however if undervolted correctly the CPU will never downthrottle because the power is being controled by an outside source..not ACPI. You can download RMClock 2.35, to both undervolt and log the CPU downthrottle if it happens. Just enable logging to watch the results. The CPU only downthrottles when it senses overheating..the downthrottle is typically during intense games, especially if you overclocked your video card. But, typically only lasts about 10 seconds..then it goes back to normal, until the temp peaks again and downthrottles the CPU again. Even with the x9100 in this machine, as long as RMClock is going I never experience any CPU restrictions regardless of how much I push the GPU.

 

Go to the exodus level in crysis and once your inside the house defending the team from alien attacks. this whole thing takes place over a massive valley with snow and all kinds of stuff its quite the scene to say the least . this level will bring a machine to its knees and when i first saw it happen. this is at 1920x1200 with most things on high except shaders at medium and post processing at low. im also overclocked at 698/970/1790 .

 

BIOS update fixed your ACPI?

 

That solution doesn't work for anyone who hasn't changed out there CPU.

RMclock only works on even multipliers and our CPU is a 8.5x multiplier. So by overclocking with RMclock you end up adding a slight constant downthrottle.

Any other solutions?

 

i tried RM clock on this machine last night but the results were the same with the throttle at that same level in crysis and i cant run the CPU at full speed i think its 94 percent . maybe in a month or 2 ill snag a 9100 or the like. im tired of spending money atm .

 

I ran all settings high the first time jsut cause I'm hard headed.. it's beautiful, but tends to slow just a tad

 

who asked ya!...*LMAO*


say.... i never thought about that either.

but...it was working fine before the update/downgrade bios...*LOL* original version 94.29 & newly installed 94.28. unless gateway is working it's way backward...lol

 

Yeah thats what I'm talking about.. because you can only do setting for up to a 8x multiplier so it will only run the CPU at 94% max, which is a big freakin problem.

 

no one can run exodus on all high. during the last part of the game it dips in frames. this is with desktops as well.

 

Tyreck i think were SOL for now with RM clock till we buy a CPU with an even multiplier lol.

 

Ya see.. I have the same problem with my x9100, it maxes at 11.5, so RMClock down clocks it to 2.98 GHz cause I lost that .5 also. However, the P8400 giving up a half multiplier will not substantially affect any of your gameplay. The GPU is such a haus, it doesn't really matter. I lose 200 CPUpoints in 3dmark cause of it..but whatever. The GPU tests still perform similar. Any games that you would want to OC with the GPU.. it will more than make up for any loss with the CPU. Honestly, the p8400 is a slight bottleneck for the GTS anyhow. Just cause of the cache. But, if you want to never have a downthrottle, and still get max performance from the GPU..just undervolt.

Believe me, I *wish* I could maximize my CPU and GPU together! And hopefully when we get a new BIOS like johnksss...we can! Til then, ya gotta suck it up. I'd rather pump my vid card, and give up a tiny bit of processor to guarantee stability.

 

Ya i know my desktop struggles with it to and its a 3.2ghz quad with a 8800gtx. but i was just talking about this scene in general because thats where the throttle happened and before and up till that point nothing .

 

E-wrecked your running the updated OEM drivers and not the Xfastest 177.85's?

Quadzilla, I'm not sure I'm all fired up about buying a new CPU. I really dislike this WiFi link card, and I think I'm going to upgrade to either the 5300 or maybe wait for the 5350.

 

you didn't hear that? Yeah man..their support page is now only accessible thru dial-up as well.. gotta dial-in to the bulletin board to access it.

 

I tried it last night Ewrecked and had great sucess when i had my 6860/t9300 with the temps etc . but with this machine it made no difference for some reason or maybe its cause i keep going back to that crysis part to use as my hmm does it throttle anymore cause if its not going to it will be here .

 

did you try the rmclock tweak which opens all the ranges. (multiplier & voltage)

 

Idk when I undervolted to .9v from I think 1.250v, and running at the 8x multiplier instead of 8.5 I dropped 450 points in 3DMark06. I'd call that significant.

 

Post linky! And does it unlock the voltages too? Because I could go lower the .9v I just simply ran out of options to select. I think the bottom for my CPU is going to be somewhere around the .875 range at least.

 

It's the lack of montevina support john.. if the CPU doesnt support IDA then RMClock wont unlock the .5 on the high end. Quad, I dont undervolt this thing for temp control..it doesnt need that. I undervolt it for stability with OCing the GPU.

 

Tyreck, go to your rmclock install directory..
Edit the RMClock_tweaks I believe, and look for VID and FID..set from 0 to 1 to unlock all. *But* it only unlocks all supported. It will likely open more voltages, just not multipliers.

 

Ahh crap.. yeah I heard about the IDA tweak that allowed .5's on the high end, but this CPU doesn't support that so I guess I'm still SOL.

 

ok, i just checked on my hp dv9700 and it has a 12.5 multiplier but rmclock runs the 13x multiplier to compensate. the cpu is a t9300

 

Bleh, heat really isn't an issue. If I can't run at top multiplier really not interested. 450 points to me is just to much in 3DMark06.

 

If P8400 supports IDA then you can unlock the 8.5, but I dont believe it does. If so, then just turn on IDA in RMClock But prolly wont help. There's some webpage I ran across that showed a workaround involving crystalcpuid to set a CPU flag..then running RMClock to change voltages..I didnt pay it much attention til after the fact..then when I went to find it again I couldnt. I just said screw it. Im fine with mine like it is. You should run 3dmark06 OC'd with your clocks using RMclock, then without RMClock and stay OC'd. Bet ya only give up 150 points on your CPU. Maybe less. It's not the overall score that matters..compare your sm 2.0 and sm 3.0 scores from each.

 

ah, didn't know....

 

Well I don't know then.. is RMclock detecting your actual CPU or are you just doing a more generic Mobile?

Ahh nm your using the IDA work around.

 

john, merom/penryn supports IDA and FSB changes - or whatever that FSB thing is called.

 

Im going to play around with RM clock on this thing again and see if i have more luck and TBH ya the little loss of CPU power VS stability on the GPU end for OCing is what i should and am more concerned about so ill fart around with it some more and see what i come up with.

 

And if someone asked about my driver, cause im too lazy to scroll back..I did swap out the XFastest for this one.. but it is a pain in the arse. Im considering going back, i had to fight to re-enable control panel. And it's like a blended 177.85/177.98 driver cause I installed over the previous driver. I'll likely go back to 177.85. Just havent spent the time yet.

 

yeah, i figured it did with penryn because i see it with the t9300. but then it used the 13x so i was thinking it would do the same with the p8400. that it would use a 9x to compensate.

 

Well then, in the spirit of a true pioneer, I'll stick with 177.85 then and wait till something displaces it or you do more testing.

So wait.. did someone say that P8400 supports IDA? Did I just miss a setting somewhere? If I could unlock the final .5 and some more voltages I'd give RMclock another shot.

Though the downside of RMclock is I might have to re-enable my page file again... such is life.

 

No no..no IDA with the chip you have. Oh, if anyone wants to take a peak.. check this out. I started a thread earlier cause I was bored..this guy just posted his 9800m GT SLI results. Impressive with no OC.

So we have come full circle and I can't undervolt. I guess I've done everything I can for now to this lappy then short of a new WiFi card and a new CPU. (From your 3dMark06 scores we seem to be CPU constrained)

 

cant undervolt? whats the deal?

 

Btw, I kinda cruised over this earlier.. but *** is powermizer? Whats it do and should it be disabled?

 

Sorry, poor phrasing. Lets go with, 'I choose not to undervolt if I can't access the last .5 of my muliplier.'

 

lol..ok. that would explain the distraught appearance of your avatar. And you shouldnt have powermizer with 177.85. But, if you do...which you shouldn't..then disable it. yeah..

 

I guess if I don't know what it is, I don't have it then! You got a link on a guide on where to check if I have it and if it needs to be disabled and what not?

 

http://forum.notebookreview.com/showthread.php?t=261929 Shows how to edit the registry to disable powermizer for Nvidia GPUs. You shouldnt have the powermizer settings..I still altered the perflevelsrc settings.

 

Thanks again, didn't have it but now I know.

 

Sweet. Well, check it.. I'm outtie. Have a good night man. Take it easy.

 

I've been having this "ACPI TZS0 temp go to 98*C" lately. I rarely play a game on battery. But I've recently been playing Eve Online, an MMO game and I don't want to log out and log back in when I take my laptop from my living room to my home-office so I just unplug it and leave everything on and plug it back in when I get to my office. That's when I noticed the 98*C.


My laptop's ACPI TZS0 temp will go from the high 45* to 98*C when two conditions exist
* I'm playing Eve Online
* I'm on battery

I can play Eve Online for an hour on power and that sensor will sit in the mid 50's to 60*. If I unplug the power cord and run on battery, and stay at the desktop, no change. As soon as I go into the game, 98*. As soon as I ALT-TAB out of the game, back to 55-60. I can surf for an hour & a half on battery and it's never a problem.

I read this thread thru page 5, but then it seemed to go off topic. Is this something to worry about?

Like I said, the only time I play Eve on battery for more than a minute or 2, is if I'm in the kitchen cooking and want to keep tabs on things.

 

Did anyone came up with solution yet?
Like install different OS to fix this problem or do a bios update..

 

I got 98c in about 5 minutes while I was running rthdribl
98c didn't go away until I exited the program..
When the temp hit 98c, FPS dropped from 60s to 40s..

 

My 6831FX is experiencing "random shutdowns" and I suspect that it is an overheating issue. The odd thing is that it was overheating under rather light loads in games, like the menus (I would close the game to go eat or whatever and it would be shut down when I came back).

I downloaded a diagnostic app called SpeedFan and decided to run it through a few loads and repeated something that I recently did to cause a random shut down, which I sat through. I witnessed the GPU hitting 100 C while each core in my Core Duo was 60 C, which is normal for the load (they idle at 40 C). I didn't push it until it shut down, but "Temp 1" also worries me - I'm not quite sure what that is (ACPI chip on the ISA bus... anyone know what that is?). I'm assuming it's the same ACPI TZS0 that's being discussed in this thread.



(ignore the suspend line in the log, I closed the lid to put it into suspend/sleep when I went to bed and didn't restart the program - that's not the random shutdown)

The random shut downs are like emergency shut downs. There's no "Windows is shutting down" screen, but it seems the programs all are shutting down in short order and when I start up, it doesn't give me the screen that says windows was improperly shut down.

I think I'm going to revert to original drivers to see it that remedies the problem. I have an Antec cooling pad that runs high, but that doesn't seem to help much.

 

I think the ACPI thermal zones are implemented differently by various vendors. I'm not sure what TZS0 and TZS1 are representative of on the P series. It could be that they are temp sensors attached to different spots on the heatsink, or perhaps they are attached to chipset temp sensors.

Are everyones fans working properly? If you removed the heatsink in the past, did you ensure that the thermal pad over the chipset was attached before you re-installed it?

 

This Thread has been inactive for a few months but I have been having similar troubles with my p-6860 FX. I have it upgraded to a T9300 CPU and configured RAID on 2x 320gb drives.

I run the laptop on an AC adapter but have recently noticed that if I play games using the battery TZS0 will jump to 98c just like everyone commented on the forum. I have the CPU undervolted to 1.000v so it does not throttle but I'm concerned about long term damage to the ACPI. The thing is I have run some tests where I ran some game while the back of the computer was open to manually test the heat and my findings have brought me to conclude that the chipset doesn't get any hotter when TZS0 reads 98c. the temperature jumps from about 48-52 to 98 in a second and goes right back just as fast. The high drop in temperature (50c in 1 second) in conjunction with no deviation in maximum heat on the sensor (always 98c) leads me to believe that it is a flaw in the sensor/bios and the heat is not really present, although I'm not 100% certain. The battery does get VERY hot after 1 hour of Unreal Tournament 3 with a slightly overclocked GPU.

Does anyone think that TZS0 could be near the battery perhaps?

I suspect that TZS0 is on the Northbridge chip but without any documentation its strictly guesswork.

 

I don't think anyone knows where TZS0 is. Replacing the thermal pad on the northbridge does help the problem, so it could be near there. I don't think there will be any damage to the ACPI. It's definitely not an accurate reading. 98C is just the temperature it's supposed to throttle back on in some of the bios (does bios have a plural?). On later ones, I think it's 86C. For some reason, it sometimes spikes if you OC the GPU or upgrade the CPU. It would spike on my 7811 in both cases. I know some people were also undervolting and just ignoring it.

Also, what are you doing playing UT3 on battery? I would try to avoid doing that if possible.

 

1. Use RealTemp to monitor your CPU's temperatures.
2. Use Prime95 to monitor your CPU's temperatures while under Full Load.
3. Get Arctic Silver 5.
4. Turn off your laptop, unplug your power, and remove your battery. Turn your laptop upside-down.
5. Upper left (while looking at your laptop's bottom), unscrew the cover and unscrew the 5 screws on your heatsink.
6. Clean the thermal grease that's on there off with 100% alcohol and a cloth.
7. Wipe it clean and make sure there's no dust on the CPU.
8. Clean any dust or stuff that's been stuck on the heatsink.
9. Apply a thin smooth layer of Arctic Silver 5 on both the CPU and the bottom of the heatsink.
10. Screw the heatsink back on, back cover, put back in the battery, turn on your laptop.
11. Run RealTemp again while running Prime95.

My results: With stock thermal compound, I ran RealTemp and my Dual Cores were running temps at Low 63C and Peak 76 (Running Prime95).

With Arctic Silver 5, I cooled the temps down to Low 27C and Peak 52C (Running Prime95).

Problem solved.

 

Hey, great! That's a huge decrease. The problem is, the spike can still occur regardless of CPU temp. There are many variables that affect it. But lowering CPU temp does seem to be one of the more effective ways of preventing it.
