7811FX new heat issue ACPI TZS0

alright thanks man i'll give it a try and tell you what happens

 

from what I understand, it somehow caps the TZS0 temp tp 87C so you will see it lower than 87C but never higher.

I can't wait to see your results.

Also, if it works for you please check your CPU temps.
Because when you dissable throttling the CPU temp will go up.

I don't like my CPU temp over 85C.

 

alright so i did it and it works. thanks so much, i can finally play games on my computer

 

so my temps are normal and then when it messes up and goes to 98 degrees it doesnt clock down

 

when i was playing assasins creed the tzs0 was still thnking it was 98 degress. but the other one was accurate and was maxing out at around 83 degrees. right now im on the desktop and its reading 55 degrees. it works great

 

so the cpu its self was maxing out at 77 degrees

 

ok, your CPU seems fine.

Enjoy the games

 

BIG WARNIGN THOUGH:

I recommend only using the file that sets the trip point to 100C.

The other file that caps the TZS0 temp is not really safe, because no matter what you do to the CPU, it will not shut down to protect itself from heat.

 

alright thanks, do you know if this would work in windows 7 because i plan on installing it when it comes out

 

It should work, but I think you would have to mod the new win 7 file.
Not sure about it though, since vista and win7 are simmilar.

Basically the mod is simple:

Search the file for "tz" untill you get to the tz scope.
TZ scope:

So that is how it's done ^^^.

 

alright thanks

 

Return(0xe93) //here I changed the passive cooling trip point to e93 (hex value for 100C in tenths of degrees kelvin) }
hey man is this the only thing i need to change or did you change anything else because im about to install Windows 7 tommorow

 

yeah that's the only thing I changed.

 

alright cool i give it try later on

 

This TZS0 temp problem was never an issue with my laptop until just recently. I upgraded to a T9900 and 2 Hitachi 7K500 HDDs and Windows 7 all at once last week. Anyway, using moral hazard's advice and dsdt100c2.zip worked like a charm for me. Everything is running silky smooth. Thanks!

 

How do I use dsdt100c2.zip?

 

PM sent, 10char

 

I did a test before the TZS0 error started causing problems and scored a 9532, after ward the TZS0 error got the score to drop somewhat and caused a visible stutter while running 3Dmark06, now that I used the dsdt100c2.zip It was bumped to 9761 and runs completely stutter free. Thank you!

I'm temped to lower the GPU voltage to 1.00v or 0.98v like others have done aswell to see how well that improves performance.

Also it took a while for me to do this since I went on vacation so I was pretty much in and out for the last month and had access to my desktop and didn't use my notebook.

 

Thank you moral! I fixed the problem! You are the best
+rep mate

and i also learned some things or two
cheers!

 

Hi moral hazard, i have a problem with my gateway p7901h. I think its the TZS0 (since ive seen it 98c) that causes the pc to shutdown. I tried the solutions you suggested but none worked, all BSOD. Here is my dsdt.asl file, hope you can find a solution.
Thanks.


It might even be the TZS1. I just ran a stress test and it went 101c when pc shut down while TZS0 was 91c. Im not sure, other times while playing games ive seen TZS0 at 98c when TZS1 isnt over 90c.

 

Ok, I will take a look, but are your CPU and GPU temps ok?

 

All 4 cores are 60c while idle and go up to 85 when playing games. GPU is 45c idle and i cant remember exactly but it does not go higher than 70.

 

And your CPU is throttling?

 

Well I just changed one line to:
Return(0xe93)

That should set the throttling threshold to 100C.

test this file:

 

I tried that and run a stress test with prime95. I put maximum heat and this time the cpu went over 100c causing the pc shut down. Maybe its not a problem with TZS0 but a general overheating issue. Ill e-mail gateway to see what they have to say. Thanks for helping.

 

Gateway just ignors me because I have a refurbished P7811 :-(

At the time there wasn't a problem and Prime95 didn't cause the notebook to overheat, but now it's happened a couple of times (overheated and blackscreen locket, the worst of the worst). Anyone knows if the new bios fixes the issue?

 

I also did this with the 7805u (the fix you posted for vic). It works great however my tzs1 reaches 101/102 while my cpu and gpu temps are low to mid 80's and it shuts down once it reaches that point.

Which line would I have to change to raise the trigger value for shutdown for tzs1? If there is a way to make the fans run 100% of the time that would be amazing too.

 

You would have to change this:

Code:

Method(_CRT, 0x0, NotSerialized)
            {
                If(\ECON)
                {
                    Store(0x20, \_SB_.PCI0.LPCB.EC0_.TIID)
                    Store(\_SB_.PCI0.LPCB.EC0_.TSC1, Local0)
                }
                Else
                {
                    WBEC(0x1, 0x20)
                    Store(RBEC(0xd3), Local0)
                }
                If(LOr(LNot(LLess(Local0, 0x80)), LLess(Local0, 0x1e)))
                {
                    Store(0x78, Local0)
                }
                Return(C2K_(Local0))
            }

to this:

Code:

Method(_CRT, 0x0, NotSerialized)
            {
                If(\ECON)
                {
                    Store(0x20, \_SB_.PCI0.LPCB.EC0_.TIID)
                    Store(\_SB_.PCI0.LPCB.EC0_.TSC1, Local0)
                }
                Else
                {
                    WBEC(0x1, 0x20)
                    Store(RBEC(0xd3), Local0)
                }
                If(LOr(LNot(LLess(Local0, 0x80)), LLess(Local0, 0x1e)))
                {
                    Store(0x78, Local0)
                }
                [B]Return(0xF5A)[/B]
            }

That will take the shutdown temp to 120C. but make sure that your temps stay cool.

I don't know how you could control your fan (apart from connecting it to your USB port to make it spin at max all the time).

 

I just wanted to say thanks for the fast response and I can say that I really do appreciate how much you've helped me and everybody else in this thread.

As always I'll monitor my temps and I do think I could improve things if I apply some icd7 to my north bridge since the cpu/gpu/assembly temps are all in line, but this will at least hold me over for a few days.

 

Sorry for the double post, I got around to testing it and it's still shutting down @ 103c. Despite my cpu/gpu temps being in the high 70's/low 80's.

I edited the tzs1 entry like you have posted here(it is line 5834 in notepad++) and then loaded it and rebooted.


*Update*
I undervolted the cpu with great success and that lowered the max cpu temp of 87c to 76c. However my TZS0 and TZS1 temps are still wacky. I'm still getting the shutdown @ 103c

The problem is apparently I didn't save my original dsdt.asl /aml correctly. So I can't revert to that and I have no idea what else to change to raise/stop the shutdown trigger. I did try to use vic's original asl but it was giving me an error when I tried to load it.

To clarify, If it's at all possible to stop the shutdowns while not having it throttle I'd prefer that route.Failing that I'd like to revert back to default settings.

 

maybe you can use this file:
http://forum.notebookreview.com/gat...-new-heat-issue-acpi-tzs0-11.html#post5304979

(to get back the original settings).

I'm not sure why the mod didn't work.

 

My DSDT file.

 

Ok, here is the modded file (remember if you have a BSOD on startup, hold F8 and boot last known good config):

 

Thank You! +rep

 

@moral hazard. Nice hack man. It's working for me. Back almost a year ago you were wondering why one of your hacks capped it at 87C. This line here is the culprit:

If(LNot(LLess(Local0, 0x57)))
{
Store(0x57, Local0)
}


x57 is hex for 87 and local0 is measured in C, not K. So there's your answer.

Kudos bro

 

Yes this is a really nice one, thank you moral_hazard! I'm still having TZS0 spiking after CPU upgrade to X9100, but due to this hack it really does not matter anymore, nice!

 

Can someone walk me through exactly what do do to stop this downthrottle, I tried reading this thread and am still a bit fuzzy, very noob when it comes to computers. Just tired of the damn fps loss after 15 min of gaming.

 

same here please please please

Im using Win 7, can somebody tell me what I need to do. Can't wait to fix my TZS

Thanks

 

For anyone who wants a guide:

Thanks a lot. I did it last night and I think it works. Will do more testing tomorrow.

 

I edited the tzs0 entry like moral-hazard have posted here and then loaded it and rebooted.

Then I run "Call of Duty Modern Warfare 2 - Multiplayer"

TZS0 temp still 98c
see screenshot taken during the game.

why is that? also I didn't notice any stuttering so far, but TZS0 still too high. Why this mod didn't work?

 

The mod does not actually remove the spiking (which is caused by a bug in the original coding), it just rises the temp limit from 98 C -> 100 C, so the computer does not throttle the performance when the spike occurs.
