great news, maybe its a kind of final version?

the one we used and flashed here for dual bios, i think it was beta and not official, wasnt it?..
[Teclast X98 Air 3G] ImJamIN:
Excuse me, but where did you see it?

I didn't see any files that seem bios.

Is it the last?
[Teclast X98 Air 3G] jcespi2005:
Seems just the Android and Windows OS, can't find the BIOS...

Guys, i have got these photos from one of our user, he also has freeze issues almost for all games, also instant heat issues he has.. He opened his tablet and sent me the photos of it.. Please see them and advise us, what can we do make it better with thermal adhesive tapes and pads in it? or does it look fine and enough for thermal cooling for tablet itself?

Please advise

i am thinking to buy these

Hi all,

My tablet freezes on every 3D game. I can never finish unity open gl 3.0 benchmark (it freezes at the beginning of this snow). I cannot run any game - Asphalt 8: Airborne, Real Racing 3... everything freezes. So - I wanted to check this thermal pads issue. As for now I didn't fix it yet (have to buy thermal pads), but opened my tablet to see what's going on there.

I attached 3 pictures

View attachment 3057387

This is a metal shield around SOC. It has some brown alluminium tape on it. But - this tape doesn't touch back lid at all! So heat is not transferred to the tablet case in my piece. Even on the photo we can see it's clear and has never touched the alluminium tablet case. So - thing number 1 to fix.

View attachment 3057388

This is what is under this metal shield. 2 blue pads. These look also almost in perfect condition, although it was glued a bit to SOC.

View attachment 3057389

And this is the SOC.

I lifted the board, and indeed - there is an air gap between display and PCB. However, some alumium tape is glued onto the display (howevery it doesn't touch the pcb board at all)

What I did was putting some thermal paste on the SOC. Then pushed the metal shield a bit. That's all for now - have to buy thermal pads.

And... believe me or not - now I was able to launch OpenGL 3.0 benchmark! Yeah - it freezed during 2nd execution, but it helped ! I was also able to play one round of Asphalt 8 ! Of couse my fix was a tiny bit and I didn't expect anything to be improved, but as you see - it helped me a bit!

So - I really start to believe this is "only" overheating issue with our tablets...

[Teclast X98 Air 3G] SUMMERBREEZE:
Thank you for your very helpful post. I also wrote a smiliar post above

I am thinking to buy these tapes and pads. The specs looks fine and i think they are best and also cheapest ones on ebay, they are made in germany aswel, i think.

http://www.ebay.com/itm/EC-360-Ther...hermal_Compounds_Supplies&hash=item19ec7bfeb1

but i dont have any clue how to use these in tablet, i am almost great with softwares, flashing etc. but not same for hardware units :rolleyes:

Can you please also, while the backcover is open, blow some cold air to the back of tablet and see, will it help while gaming or benchmark?

Is the new version C8J7 also has problems with hangings and restarts as was mentioned at the beginning of this thread? My old one which I ordered in October I gave back and I wonder if not buy again ....
[Teclast X98 Air 3G] SUMMERBREEZE:
yes almost %60-70 of C8J7 devices do this, most of owners dont know this at all because they mostly dont play very heavy 3D games, i guess.

Testing, throtling

Mike Cane posted a link to iambillbil on turbo speed behavior of the intels. http://mikecanex.wordpress.com/2014/12/09/iambillbil-calls-out-intels-z37xx-cpus/

Interesting stuff, but not very clear yet. Turbo is never intended to be used continuously, right, so downthrottling must occur at some point. Could it be that this is not what happens before freezes, that the cpu stays at full speed? maybe worthwhile to do some testing with a cpu monitor app. Also, the stepping down in clock, what part of the system determines when this happens, chip, bios, kernel? There are some apps in the Play store that claim to be able to manipulate the max clock freq, given the right kernel that supports this, Anyone tested this, does it work?

The story is

Teclast release 10 pcs dualboot tablet

Let's say beta...

Then one Chinese guy dump the bios

Then now new dualboot tablet C9J7 is release by teclast... Let say final version

But teclast will release new tablet again soon, they love to do.... Don't care much abt older model/customers.... To greedy?
[Teclast X98 Air 3G] Hendrickson:
Okay I just ripped open my Air II and it doesn't have the heat shield around it like your pictures. Must have something to do with stopping interference from the modem?

[Teclast X98 Air 3G] quetiano:
Hi again guys. I am a newbie and I reside in South Africa, I have just purchased the Teclast x98 3g air with Windows 8.1 already built in. My question is, how do I get the tablet to boot into my usb stick because I have tried everything that I have searched for on the net and even in here but my tablet just refuses to boot via usb ! I have went into bios and enabled to boot via usb flash stick already inserted and it was shown in bios but did not work, even tried from within windows 8.1 where you choose to restart into recovery and chose the usb stick with efi, but that also did not work, so I am sooo boggled right now. Off course I might have nissed something in these forums but with so many pages of posts to go through, it will be another mission.

Does anybody have anything for me to try so that I may boot this tablet into a usb flash stick, I would like to re install windows 8.1, a proper english version that also works better than the already installed chinese version with english language pack !!!

Thanking you guys in advance,

Rephan

guys, if you have android, please install this app, it is CPU temp, it is analyzing the changing curves of your tablet. Run it and leave the app on CHANGING CURVE tab. And leave the tablet in IDLE.. Dont make any work with it, lets see in half an hour or in 1 hour, what wil be your max CPU Temp? Mine is always around 40 C and max in idle i saw even 44 C which seems high to me.

https://play.google.com/store/apps/details?id=com.yanyan.cputemp

if you dont have google play working, download from THIS LINK

You can do the same thing windows too but i dont know an APP for Windows 8.1, if you know any, also do a smilar test and share your results
[Teclast X98 Air 3G] acc007:
No, it's C8J7.
[Teclast X98 Air 3G] SUMMERBREEZE:
Guys, if you are on android, dont forget to change your launcher (with Nova or Apex) and DPI setting to 264ppi by NOMone Resolution changer (needs root)

I sent a PM to you, please respond :o
[Teclast X98 Air 3G] Petepe10:
I do not think the idle temp is awfully important, why would you want to know? It seems possible that a problem could be that under heavy load the speed is not lowered when the temp becomes too high (which in turn could be due to poor heat dissipation). Still does not explain why sometimes crashes occur very quick. That looks more like a voltage problem. It would be interesting to study how good vs bad tablets compare in both temp and proc speeds.
[Teclast X98 Air 3G] SUMMERBREEZE:
the thing is [MENTION=2198172]mirek190[/MENTION] s tablets and maybe some others tablets are working around 20-22 degrees in IDLE and mine is working around at 40-42 degrees in IDLE. do you think this is normal for exactly the same device? I want to see others results too, if we are also talking about thermal coooling&spreading problems about tablet, i believe IDLE temp is also important, especialy for the general health of the device
[Teclast X98 Air 3G] acc007:
mine has around 37 C deg at idle
[Teclast X98 Air 3G] Hendrickson:
I predict it will be the same Air 3G/ Air II base and dual OS, the only, but welcomed change - A 64GB eMMC :)

And if I was dreaming it would the Atom z3735 or z3775 dual channel 2GB ram 17 Gbs Vs our 10Gbs. And usb 3.0 support.

I think you might have a bad thermal pad under that metal housing over the soc. Might pay to open it up and have a wee look under the hood.
[Teclast X98 Air 3G] Jiri_S:
The thermal tunning

The thermal tuning of my C6J6 has been done. Before the tunning I had same trouble with temperature over 60°C and freezing of the tablet as others on this forum. So today I opened tablet and made some changes in thermal design. After that I tested Asphalt 8 and RR3 and maximum temperature of SOC after about 20min was 52°C without freezing. I am happy now :)

some pictures:

Initial situation (including wrapped corner of the foil from the manufacturer):

I replaced two blue rubber pads by two small aluminium (I did not found any cooper plates at home) plates with thickness about 0,4 mm and gray thermal grease (for CPU cooler) instead of the "glue" on both sides of the aluminum plates.

I tried use thermal grease also between the cover of SOC and the lid bud unfortunately there was "big distance". This picture is after reopening the tablet.

So I use "blue rubber" pads for this purpose.

(sorry for my english)
[Teclast X98 Air 3G] acc007:
Thanks for your report, Jiri_S ! In fact I just emailed SUMMERBREEZE about my thermal fixing thoughts and see you're another one doing the fix! So, it looks that:

1 - 0.4mm is thick enough to put between SOC and metal shield. Did you have any problems with closing this metal shield? There are latches on the pcb to make it fit, any problems here?

2 - there is a gap between metal shield and back cover, the same like in my tablet. It looks like there is at least a space for next 0.5mm, maybe 1mm, don't you think so?

3 - you still have an area to improve as PWMx mentioned, you could use thermal pads between a display and PCB. In my opinion there is at least 0.5mm air gap, maybe 1mm?

Also, please answer me this question - were you able to perform Open GL 3.0 benchmark (from unity) BEFORE this operation? Are you able to do this benchmark now, AFTER this thermal fix?

I think I need to find some copper plate around and try with it... should be much cheaper than thermal pads (althought it's not stretchable at all).

Anyway, you're another one whose story confirms that thermal fix might fix our tablets !
[Teclast X98 Air 3G] michal1148:
I installed it, everything is fine, do repairs here and touchpad gsenzoru. but unfortunately gsenzor somehow angry.

Orientation in registers is 00 00 00 00 00 00 00. In landscape that's fine and turns correctly but the height is turning upside down. Does anyone know how to change the registry?

Thank you very much
[Teclast X98 Air 3G] Jiri_S:
1 - without any problems - thickness is similar to original blue rubbers pads

2 - IMHO about 0,5 mm

3 - yes but there will be better some thermal foil which I did not have. There is smaller gap I think about 0,2-0,3mm but It can be case by case.

The Unity benchmark now run without any problem. Before redesign sometimes tablet froze.

PS: bad news - RR3 crashed again - there is maybe some other problem.
[Teclast X98 Air 3G] mirek190:
Are you using dual boot bios ?

Because in my observations has higher voltage than normal bios. Because on one of my tablets I had normal temperature but was still freezing in RR3 but after change to dual boot works competently normal .

I used this bios ( for C6J6 and C8J7 ) https://mega.co.nz/#!sggiHaBC!3xH30UrQVbR98Gdc8HkFNwbz80yZn5GSJasrE6pWI0o
[Teclast X98 Air 3G] Jiri_S:
Currently I am using last BIOS from Teclast site:

BIOS DATE: 10/24/2014 17:09:00 Ver: 3G068i101

Small update: now is tablet warm from both side (the lid but also the display near the cpu) so filling gap between the cover of cpu and the lid make press on the pcb and better contact of the pcb to the construction of the display.

fix inverted touch

if you have inverted touch problem just unistall intel hd graphic and mark "delet driver software for this device "and click on restart later and install this latest driver from intel website

https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24346

next click restart later

and then download and run that file registry i attached to this post

and restart your tablet all function work perfectly except camera

you can use many cam for fix this problem

i think this best solution for this problem

In that case you don't use dual boot ? You should try has probably higher voltage

Dual boot has date 02/12/2014 is newer.

I has good low temperature from beginning but still was unstable until I update the bios.

Heat where?

Good to see that there is progress is solving the problems. Bad that the Teclast thermal design or quality control does not prevent these problems.. Anyhow, I was just wondering: some suggest to fill up the air space between soc MB and panel, right? Is that wise and ok for a panel to get hot? Isn't it safer to try to get the heat to the back surface of the tablet? So focus on contact between soc cover and back panel (and maybe not needed to replace pads under cover?). Just curious (mine has not arrived yet, hope I do not need this, just killing time... :o)

Obviously you guys haven't been reading my tutorial... Answers are all there.
[Teclast X98 Air 3G] SUMMERBREEZE:
You might be right, it will deffo help for cooling bit in the other side, touch panel will get hotter than before. Maybe first try to do modifications inside the metal lid of SOC- on cpu, drams and eMMC etc and also just on it (between the back cover and metcal can) I am thinking these on cpu and other chips.

http://www.aliexpress.com/item/10PC...-Sink-for-Laptop-GPU-Graphics/1747241965.html

and between the metcal lid and backcover, to full the gape (6 pcs)

[Teclast X98 Air 3G] jcespi2005:
mate, don't you have a little issue not being able to see the app description on the right panel with Google Play on this DPI configuration? Or is just me :confused:
[Teclast X98 Air 3G] Petepe10:
I would think that if you use metal & cooling paste all components must make very good contact, so with pressure of back cover to components, or be glued. I would be inclined to use copper and paste inbetween socs and soc cover (assuming the cover fixing is strong enough), and flexible material (coolpad) between soc cover and back, also because the back cover is probably slightly curved. The last bit is easiest and may have the biggest effect since there are already blue cooling pads on the chips.

Anyway the one I am getting is a replacement for a faulty p90hd - hope I have more luck this time.
[Teclast X98 Air 3G] jcespi2005:
Sounds to me like the first one is just the Android OS, and the second one is the first Boot USB with WinPE.

BIOS should be one compressed file around 7-10Mb
[Teclast X98 Air 3G] Jiri_S:
The space between cover of the CPU and back surface need not be symmetrical so I would prefer some elastic material like silicon/rubber thermal pads. And also I don't think that there is such big gap (1,2mm) - from my point of view there is max 0,5mm.
[Teclast X98 Air 3G] keepfishes:
I know, what I meant was that the BIOS file might have been packaged all together into the zip file. I'm not sure...

Hello,

Mostly it was supercows that did the job, but as far as I understand, it is easier than flashing of android based tablet since you can flash the bios from windows (I have windows at the beginning). Afterwards we flash android than install windows. So the process, is roughly the same as other tablets.

No I didn't notice any such a problem on C6J7, the battery arrives at 99% but honestly I never let it go until 6%, may be I should try this out and see what happens.

At the end, I think that those three models are the same hardware wise, my android now is from C7J8 but it's working fine, for now.

Ah yes, I still have the camera inversed but it's weird, since it is inverted in skype but not when I open the camera, I don't understand what is happening.
