[MTCB Hardware Development] Johny DJ:
You can get rid of the lag by removing playstore and installing fake one, its the same like upgrading to 2 gb ram, but you don't have to...
[MTCB Hardware Development] Nomader0:
mate, i am the one who discovered that playstore is the problem...
[MTCB Hardware Development] Johny DJ:
Sorry did't know that, was just trying to help...
[MTCB Hardware Development] Nomader0:
no problem mate..

disabling google services and using microG helps a lot for sure, but try to run tomtom or a heavier app and you will understand what i mean..lagging is lagging.. the ram is to low in these devices..
[MTCB Hardware Development] colostro:
I'm using microG and finally i don't have laggy running TomTom

[MTCB Hardware Development] Johny DJ:
When I started to use microG all the laggy staff got away, no skiping songs or sound and google maps became usable, before they were not... I'm also using iGo but newer tried TomTom, so yes it could be laggy, I'm also missing 1 gb of more ram...
[MTCB Hardware Development] reggiexp:
Yeha so 2gb is a must on android anyway.
[MTCB Hardware Development] Oberbergler:
I have two 1 gb chips if someone still need them. I was in the 1st group buy, but my unit has a strange problem. It is switching off spontaneously sometimes, so it is not worth to update the ram.
[MTCB Hardware Development] javiermi:
I did receive my 2 ram chips last week and tried to solder them instead of the original ones

Long story short: I screwed up and now the Unit is unusable

I have some experience soldering , but these BGA chips require more than usual skills, so even I put a lot of heat on them the balls would not solder properly, that and a broken track, that was the problem

Hence my advise is: do not try to replace the chips unless you are confident you can do it ( and have the experience)

I have managed to source a new board, but unfortunately is only 1 GB

I may have to resort to microG
[MTCB Hardware Development] typos1:
Or pay someone to install the other chips.

[MTCB Hardware Development] Johny DJ:
Just one ram? Didn't you change both to have 2gb?

I asked about 5 pros to made the soldering but each one said that is 50/50 chance to work after soldering...

Is that really so risky?
[MTCB Hardware Development] Oberbergler:
I have 2 ram chips with 1 gb to ship from Italy if someone still need them.
[MTCB Hardware Development] dafior01:
Two RAMs replaced. Have now 2 GB. 25$ is cost for replacing both of them ;)

I do not know why they told you 50/50. Always you can say it ;). My service told me that is no issue with replacing. I do not know. Perhaps risk is depend on tool they are using.
[MTCB Hardware Development] Johny DJ:
Nice :)

Will try and see how will go. They told me that they will do it with a hot gun and extra flux before they solder but they are just scared if the plate from china is bad made :)
[MTCB Hardware Development] pjotr_weliki:
Why should the quality of the plate be bad made? Look here https://xdaforums.com/album.php?albumid=14157
[MTCB Hardware Development] Johny DJ:
Do you maybe know where to get these ram specs ... soldering temperature etc ?
[MTCB Hardware Development] deedeebulldog:
You can get info here http://www.intelligentmemory.com/dram/ddr3-sdram/

most chips are very resilient and can handle a few reflows or reballs. my advise is to change out the unleaded solder spheres that they come with for stronger leaded ones if you can. Leaded spheres also have a lower melting point.
[MTCB Hardware Development] Johny DJ:
Thanks for the info, will take your advice for soldering etc... but probably wont find anyone for reballing once again.

[MTCB Hardware Development] oskaratk:
you need 2 chips.

I do not "sell" those chips at all - this is still the group buy, luckily I had bought extras. If I would sell them on ebay, they would be way more expensive.

Group buy shipping

One forum member ordered 2 sets, shipping international plain letter - which is inexpensive, but not trackable.. Claims not to have received the shipment and now opened an PayPal dispute. I have refunded the person and will eat the damage.

Consequently, in the future I will ship trackable (registered) letter only.

[MTCB Hardware Development] KaMu1219:
That's a pity. You sent it to me as plain letter, being aware that the risk is on my side (the letter arrived safely).

When all hope looked lost, i managed to find an Phone repairer to do the job. Took him about 20 minutes to do the job and cost $AUD 80, and now officially say i'm part of the 2GB team.

[MTCB Hardware Development] thewoZa:
You'll all be better just buying a new px3 / px5 board with 2gb+ on it already. Plenty of links / info in the forums already...
[MTCB Hardware Development] typos1:
Not if youve got an MTCB/C unit - no 2Gb SoMs exist for them.

And if you have an RK3188/PX3 MTCD/E unit, its far cheaper to add 1Gb than buy a new SoM.
[MTCB Hardware Development] thewoZa:
If you have the skills to solder the modules yourself...
[MTCB Hardware Development] typos1:
Or the skills to pay someone to do it for you.
[MTCB Hardware Development] thewoZa:
Which then costs money and invalidates your argument
[MTCB Hardware Development] typos1:
Not at all, it doesnt cost much and its still cheaper than buying a new SoM.

As I have said, MTCB/C owners cannot buy a 2Gb SoM because they dont exist, so they have no option but to buy the RAM as buying a new head unit costs twice as much a SoM.

I read that before hence why I didn't quote it in my reply...

[MTCB Hardware Development] evronetwork:
I'll check my memory chips and what to fit there, although I have a hot-air station, I can't do reballing.

After finding out what ram chips I need I'll ask a specialist about the pricing, if the price is right I'll do it. Else well a new Octa core, 4GB ram, Android 8.0 costs about 250 Euros, so if reballing is cheap I'll do that else none or throw this and get an octa core unit.

P.S. From people who have done this, is the boot time reduced?
[MTCB Hardware Development] typos1:
All the info you want is in the original threads. Do you have MTCB/C or MTCD/E ? If you have MTCD/E you just need a new SoM, you dont have to buy a whole new unit.
