DM 800HD se clone

Re: DM 800HD se clone

So is the total physical memory = (/dev/root) + (tempfs) + (MemTotal)?

Yes, more or less.

Thanks aplok

Would you please test this too: cat /proc/meminfo

in my opinion, if you cool dm clone all time long, there is a lifetime warranty for it (except thunders or you gige manually a short circuit)

Sorry I'm not following. Please be clearer

some mem stat with top :

Re: DM 800HD se clone

Thanks Gianni!
That's a relief

I tried df -kh, and I got:

Filesystem                Size      Used Available Use% Mounted on
/dev/root                60.0M     47.1M     12.9M  79% /
tmpfs                    64.0K         0     64.0K   0% /media
tmpfs                    64.0K      4.0K     60.0K   6% /dev
/dev/sda1                 3.7G      2.1G      1.6G  57% /media/usb
tmpfs                    67.1M    584.0K     66.5M   1% /var/volatile

So is the total physical memory = (/dev/root) + (tempfs) + (MemTotal)?

I think it would be of more interest to discuss if a vu clone is better quality than dm clone and this is a difficult choise to do if you plan to buy a new box.

Re: DM 800HD se clone

Linux kernel only uses a part of all physical available ram.
The remaining is allocated at boot time for other purposes.
For instance, try "df -kh" and you will see memory allocated for tmpfs filesystem.

Re: DM 800HD se clone

You are checking memory usage: the box is using 137 of 256, isn't it?

regards

MemTotal:       137348 kB
MemFree:         41720 kB
...

The second line indicates the free memory

Re: DM 800HD se clone

I bought DM 800HD se clone. Thanks all for your help.

There is something I'm worried about though:
When I check the memory using

cat /proc/meminfo

I get:

MemTotal:       137348 kB ...

Shouldn't it be 256 MB or I am missing something?

Can anyone who has it test this?

Re: DM 800HD se clone

I agree mate: I've bought a bunch of low esr capacitors for few euros and when a power supply fails a can fix it in five minutes and 20 cents.

Yes mate, that is good for you
but not all people has the ability to fix circuits by it self or to find a good repairer with low cost.

[gianni253]

Re: DM 800HD se clone

But if you tested it and it's working properly, the matter of replacing a capacitor when it goes bad won't be too difficult.

Re: DM 800HD se clone

In face of this reports is better give more money and buy another box with good support from sellers.

Re: DM 800HD se clone

Basing on my direct experience, 99% of problems are given by bad electrolytic capacitors.
Within this 99%, 90% are capacitors in psu unit, the rest in network section.
I don't think you will receive a good support from clone sellers, so you have to repair boxes by yourself (with a little skill in electronics and soldering),

As said gianni253, the most problems are in motherboard.
Faulty capacitors or other electronic parts on the m/b is the main cause for the broken clones.

The network stop working, the tuner don't work properly, the box can't power up... and many other problems.
The psu also have very serious problems and must be changed after 1-2 years.

All these parts need a special electronic who know about SMD circuits and fixes in order to be repaired.
In many cases the money that the repair costs is higher that a new clone, so these broken clones go for rubbish.
When a small fix is needed, this can be done easy by someone who know some things in electronic circuits.

Re: DM 800HD se clone

another specification of china clones are the electric adapter is made from very poor material.

Also wanted to add, that there are 2 types of clones, original company clones: made in PRC and unregistered clones (radiation materials used as in toothpaste like Colgate).

Re: DM 800HD se clone

Yes, my friend. I have a DM500s with 7 years old and still working without problems. The question is: the % of problems in dm clones is big or not? And if we have problems who makes the reparation?
