Acer TimelineX 3830/4830/5830 T/G

[ajnauron]

After testing for eight hours, I've found that after installing Nedemai's modded bios(The version that does not touch the vbios), setting thermal throttling to 90C, the GPU no longer causes throttling at 75C, at least on the i3-2310m model.

I had the GPU running at 89C(as recorded by MSI Afternburner) along with the i3-2310M running at 16x the entire time, and the CPU only started to throttle(very slightly, to a 15.xx multiplier) when the CPU temp hit 85C.

The amount of throttling seems to be dependent on CPU temps, the higher they are, the more throttling occurs.

The main problem is that neither the GPU nor the CPU internal sensors can read and record temperatures of higher than 89C for the GPU or higher than 85C for the i3-2310M CPU, with this modded bios installed, though I don't think they could before. Before installing the modded bios, the CPU would cause thermal shutdown at 85C instead of throttling.

The method of throttling is also different now. It used to throttle immediately to 12x, but now it throttles based on CPU temperature, with the GPU having no effect on throttling, as far as I can see.

for me it can perfectly read temps above 90C as for gpu and cpu aswell...

right now i have msi kombustor running for couple of hours with temps maxed out at 96C (ONLY gpu load) and after lifting laptop back - after 2-3 minutes it's 89C now and still dropping... so - we need a cooling plate under laptop and remove that damn grill cover under... i go to service, pay em couple bucks and hope i will not loose warranty

I'm ordering some of these to stick on the GPU.

hey anyone seen the latest supernatural episode?
roman was using a 4830.
our laptop boys are growing:P

to CoLDFIRE: Hi, please you have3830tg as I too, now I have 2*4gb ddr3 1333mhl cl9, but I read in your info 16gb. this nb acer aspire 3830tg support 16gb? I mean if only 8gb. And second question what is bios version 1.10 unlocked? I have in my notebook last version bios 1.10 but on acer website is only one version,about unlocked version isn't information, thanks for your reply.

Hi PepeCZ, yes I have 16GB and it works perfectly and also many other members here put 16GB of RAM in their 3830s successfully. As for the unlocked bios I downloaded it from this thread, thanks to Nademai he unlocked it. Refer to the second post in this page: Acer TimelineX 3830/4830/5830 T/G

I doubt it would work as there's no option in BIOS to boot from it.

I think it's possible if you installed Windows first on the primary hdd then installed another copy of Windows to the mSATA drive since windows always writes the boot info to the primary drive. Then, you could just delete the windows installation from the HDD. The only problem here is that there's no way to install an mSATA disk in any of the current TimelineX laptops, unless you plan on soldering it to the board which is NOT easy and could easily turn your laptop into paper weight!

I have an issues with lower GPu voltage bioses:

in fact if i start kombustor, my GPu voltage for start is 0.90, and only after some time it goes to 0.85.

But, in Acer bios, which changed the GPU VDCC to 0.85 it was from start.
so, this is a bad sign - not all has been changed. Maybe bios developer can work this issue out?

0.80v version is buggy - 0.80 volts is not enough for my gpu to run at stock speeds. maybe you can have 0.82 volts for gpu to be set?

Or can we find a way to control this voltage from os? like msi afterburner allows me to do so on my desktop?

anyone else having high-freq noise from right side of laptop? heard from right side? near enter key. only happening when under load.


So, you can maintain you laptop using CPU burner such as linx avx edition and furmark/kombustor heating gpu and no shutdown?
Can you make a screenshot with temps and settings you use for such heating?

thank you

The noise coming out from the right side of the laptop is most likely due to the HDD.

Though I haven't tested much using any synthetic benchmarks, I played Skyrim for 2 hours (x26 multiplier - 760Mhz GPU clock - Medium settings - 720p - FXAA On) with the laptop sitting on a cooler) and here's a screenshot of the temps after I exited the game:

I'll try to do some benchmarking with 3dmark/msi kombustor and I'll post the results as soon as I can.

Okay, GPU 85 and CPU 68...

Mine GPU at stock do this heat After a hour running pretty heavy benchmark standing on my cup of tea for lifting back...

> The noise coming out from the right side of the laptop is most likely due to the HDD.

Nope, this only when i load my GPU - high frequency noise, like mosquito

[pasoleatis]

to downloads: ok,no option for boot in this notebook okay. but what option: in bios set normal hdd on boot and on this normal hdd install some application for select boot devices and now select msata on normall hdd install application for select boot device.this would not work?
it is a pity that this bios is not an option, maybe if the bios modified by adding this option only.
to pasoleatis: hi,i feel that there should be or not?now I'm not surei'll probably have to disassemble laptop again and look on it.

Hello,

In the old days when we were running Windows 98 Se there was partition magic program which came with many utilities. One of them was a boot loader (boot magic maybe ). It is also possible what the other persone suggested a few posts ago. To install windows on a normal hdd, then copy it on the msata and jut have the boot loader.

If people are having issues with the modded Bios I would like to point out the 5830TG mods for the vbios are buggy and seem to not work well with the 0.80v mod. I would adjust this but I've not had time to sort it out and I only own a 3830TG model as well... so testing is difficult.

That being said each machine is different and the tolerances of the GPU will vary. Please do not expect that every machine will run a stable GPU at 0.80V, it wasn't designed to run this low... its just nice when it does.

If you are having issues it is also very helpful to know the model of machine you are running. This allows me to sort out why the issue is occurring.

@ajnauron I've noticed somewhat similar behavior with my 3830TG. Difference being that the GPU will still cause a 12x multiplier throttle once it hits 75C and the CPU won't cause throttling at all.

@Yuna if you want to control the GPU voltage from within windows install the stock Bios and try nvidia inspector. This tool allows one to change clocks and voltages from within windows and does work with my 3830TG.
