The Definitive Guide to Acer Aspire Gemstone Blue Throttling Issues

i'll test the 2.0 will get back on the results.

@Abraxis, does that mean it doesn't throttle when cpu is 100%, any less it does?

 

After stopping the test (game still running) while uploading the OCCT attachements and writing this, it throttels again...

 

@hna

sound strange but looks like...

 

so moral hazards fix don't work for me...

whats the difference between morl hazards an weinters fix?

 

It is the same I just integrated the fixes into the BIOS directly so you will never need to overload DSDT again.
Anyway is it the CPU or graphics card?
Graphics Card do throttle sometimes.
OCCT test do not stress the GPU.
Your in game issue could be due to GPU throttling.
Darksilver tested moral's DSDT patch and gave the green light.

 

i thought you were trying weinters fix, don't the difference but the latter seems better

 

no graphic card isn'T throttling..it is forced to max performance by riva tuner. An if the Graphic card does u wont see it at the RMC Monitoring afaik, because just shows CPU throttle.

 

Try this:
After overloading Restart then test.

 

as u can see here, while throttling graphic card stays at max performance

 

restart what?

everytime after overwriting the table i rebooted the notebook.

 

Oh ok refer to Dark Silver then...

 

fyi:

i've the throttling issue just while gaming. If i do prime95 stress test e.g. theres no throttling. So i think graphic card could be a cause, but have no idea in which way.Graphic card overheating shouldn't be the problem as u can see in the screenshots.

 

hmm dark silver do have a 6920G and i do have a 8920G. If i understood u correctly that doesnt make any difference, but maybe it does.

weird..

sometimes it feels like i doesn't depend on temperature at all. Throttle starts sometimes with GPU<80° an CPU<50°

 

Or if you are an extremist try removing all the throttling functions.

 

how high is the risk?

and could u tell me all that is connected with throttling in the dsdt.table?

This topic is completely new to me.

 

No risk as long as temperature remain within limits
The point of ACPI throttling is to define which Device is monitor by ACPI.
If you remove both CPUs entry then it will not be subjected to throttling at all.

 

OK,

i don't know exactly what u mean, but i'll search the dsdt.asl for cpu entrys that does make sense?

 

Remove the whole _PSL entry the PSL contain the device to be throttle which is the CPU

 

This should be helpful

 

or maybe something inhere:

ThermalZone(TZVR)
{
Method(_TMP, 0x0, Serialized)
{
Store(VRTP, Local0)
If(And(Local0, 0x80, ))
{
Subtract(Local0, 0x100, Local0)
}
Return(Add(0xaac, Multiply(Local0, 0xa, ), ))
}
Method( _CRT, 0x0, NotSerialized)
{
Return(0xed0)

because of the _CRT and TZVR and TZVL are much higher than TZ00 and TZ01.

and to be honest, i do not no what excactly to do to:

 

ah ok thank u!

 

so after reading all this i would delete these lines completely:

Method(_PSL, 0x0, Serialized)
{
If(MPEN)
{
Return(Package(0x2)
{
\_PR_.CPU0,
\_PR_.CPU1
})
}
Return(Package(0x1)
{
\_PR_.CPU0
})
}
Method(_PSV, 0x0, Serialized)
{
Return(0xe93)
}

 

but why is this just within Thermalzone TZ00, what if anotherone triggers the throttle?

 

Weinter do you have 2.1 SLIC which is not using BIOS flashing?
Just like using MS ASL Compiler?
I wish I can do it without flashing. I mean after I install Windows 7 and then, I edit the SLIC myself. After that, only activate the Windows 7.

 

do you have vista? if so, try the 1st filed (SLIC 2.0)

 

I mean I just want the better patch. Since our BIOS is 2.0 SLIC only, I want a newer 1 with 2.1 SLIC. But I don't dare to flash BIOS. So, I was asking for a 2.1 SLIC patching using ASL Compiler.

Anyway, I have used the Moral Hazard's modded DSDT.ASL. It works great!

 

isn't a bios mod better than the registry mod by moral hazard? have you tried the bios mod?

 

As mentioned, BIOS modding need to FLASH the BIOS.
Flashing BIOS can be deadly. So, I don't dare to try.

Moral Hazard MODDING, is registry type. But it still does the same thing.
DSDT table reading is getting from BIOS. But I don't dare to flash the BIOS(dangerous).
So, editing the DSDT table manually is better and safer.

 

But why does'nt it work for me?

I did the same thing like u.

 

Did you put the new DSDT.ASL which MoralHazard edited into the C:/ACPI folder? If you asked to replace the file, allow it. You can do the backup of the original file if you want.
After that, only proceed to 13-15steps stated in the blog.

 

I modded a Acer 6920G before using the new Acer SLIC 2.1 before the DSDT Patching and stuff in my blog so take a look.
Edit:
I got what you mean.
SLIC is not inserted via DSDT there is no patch.
It is inserted into a ACPI BIOS Module.
For my SLIC Mod I simply replaced 2.0 table with 2.1 no other changes.
You can try to use a loader where the SLIC is inserted into memory at boottime using GRUB but it is easily detected not sure if it will fail on Oct 22.
A BIOS mod is as good as the OEM original BIOS due to the similar methodology so it is very difficult to detect and destroy.
I am using a Modded BIOS personally.
When I mod BIOS I do check the integrity of the BIOS Modules.
After I mod I open it up again and make sure those modules I did not change matches the original module checksum so it should not brick if the flashing was successful so far I had no one telling me my BIOS failed.

 

@ Dark

Yes, i did.

 

I would like to see if Moral hazard's method works for me (if he's still available). Here is my dsdt.asl
I've got an Acer Aspire 6920G with Bios 1.14

 

Weinter, have any way to get SLIC 2.1 other than flashing the BIOS?

 

my BIOS is v1.14 and laptop model AS6920G. here's my asl file:

 

1)Loader
2)Stick with Vista

 

I want Loader. By the way, what is the Loader?

 

I have modified another DSDT.
I added "Store (0x64,PSVT)"
1)Remove the .txt extension it needs to be .ASL
2)Make sure it becomes DSDT.AML before overloading.

 

Do you know Linux?
It boots using GRUB right?
What happen is someone modified GRUB to load SLIC into specific address before going into Windows.
However it can be easily detected for now it is still ok not sure about future.

 

what does "Store (0x64,PSVT)" do?

 

It makes sure PSVT is 100 in decimal so it will throttle at 100degrees.
I took it from a example in the ACPI Specification PDF.
I will do the perm fix when it is finally tested and agreed by ALL that it stops throttling.
I have modified another DSDT.
I added "Store (0x64,PSVT)"
1)Remove the .txt extension it needs to be .ASL
2)Make sure it becomes DSDT.AML before overloading.

so this is the same method as moral hazard or different?

 

Different Moral Hazard hard coded a value.
While what I did was assign a value to PSVT.

 

when i compile it with asl, this is what appears:

EDIT: i've tried your asl, it doesn't work. the cpu throttles

 

ok, I put it in feoras.zip

ok, I put it in hna.zip

 

Is someone inhere with an 8920G that could fix the throttle with Hazards Method?

 

@Abraxis,

I can try to cap your TZ temp to 50C.

That could also work.
Let me know if you want to try.

 

Yes of course i would like to try. So the effect is, that the real temp is always overwritten by 50°C. And is there still a critical shutdown (like 100++°C to prevent hardware damage, because this should stay for emergencies)

I appreciate every single help from all of you. And hopefully my notebook will be fixed somehow too.

What about deleting the lines i posted after weinters suggestion (complete PVT)? Are these the correct lines? Hadn't read any feedback to this post.

 

No, critical shutdown would be disabled too

Yes I think you had the correct lines. It could work.

But you might get a blue screen next time you boot. If you do, remember to boot last known good config to restore the original registry.

Good luck.

 

thanks moral hazard. the fix seems to be working, i've played tomb raider underworld for about 40mins and no throttling occurred. will test some more.

maybe someone should send this fix to acer and make an official bios out of it.

EDIT: I've also played STALKER Clear Sky, no throttle!!
