I assume that's going to be the third series of libre cards right? you
making a lowrisc based processor and graphics, etc,

more likely the fourth or fifth. all these things happen in
parallel. the one after the RK3288 to investigate is the RK3399
(6-core). also i've heard that the iMX7 is out so am having a look at
that.

Post by zap
I am sure you can succeed. I look forward to still getting the second
revision still though. :)

According to this the rk3399 has support on everything. Does that mean that
it does not have any gpl violations or blobs required ?

as best i can make out that would be a correct assessment. what i am
missing is a reference design. it would be a total waste of my time
and highly irresponsible to try to start from scratch, so i'll wait
until a design "percolates out" onto taobao :)

RK3399... 11.0 ghz speed if you count all the four cores which are 2 ghz each and 1.5 for the other ones...

wow...

I wonder how much watts that processor uses...

that is crazy fast. I mean really... 4GB ram too I see as the norm. which is good.

on a different note though, perchance will the fourth or fifth series of libre cards support 8gb of ram or more?

I bet you could even get it to 16gb if you wanted... though that wouldn't be needed. heh.

I am impressed by your findings keep it up pal... hehe.

the cost of the RAM ICs to do that are insane. the 1GB DDR3x16 ICs
are already $10 **EACH**.

normally a DIMM would have 8 or 16 RAM ICs, meaning that for a 4GB
DIMM you need 8x 512mb ICs, or you could do 8GB by using 16 of them.

normally you get 2 (matched) DIMMS totalling 8GB.

if you want *32* GB you get 2 matched DIMMs, but nobody in
"mass-production" is shipping windows PCs or laptops with 32GB of RAM
(and if they are it's DDR4)

additionally, it would need either 2 pairs of x32 DDR RAM
controllers, or it would be necessary to do a cascade layout: a
daisy-chain of RAM ICs.... and i'm not sure it would be possible to
fit 8 RAM ICs onto the 43x78mm PCB anyway.

bottom line it's far too expensive and quite impractical. 4GB is the
practical limit at the moment and even that's stupidly expensive
relatively speaking.

Ah... okay I had no idea it would be that expensive if you made it from
scratch. my bad.

I will add that 32gb is absolutely insane and even 16gb is.

I wouldn't need that :)

8 would be my limit and even that is a want per-say... :)

but if it would be impractical then screw it I say. :)

hey not a problem. just have to keep an eye on prices for DDR3 (and
DDR4 when it's more popular for ECs) over the next few years.

There is currently a cartel going on on ram ICs. Once the chinese offered
the last american ram producing company( I forget it's name) to move its
production to China, ram pricing started climbing, the company is healthy
again and we are still seeing price hikes, so China is for once investing
in homegrown production. My guess it will be no earlier than 2019 before we
see prices dropping again.

*sigh* now why doesn't that surprise me. i mean, DDR3 800mhz can be
done in 90nm for god's sake.

This is so true. Especially on DDR4 sticks they're basically price fixing
at this point.

Well considering what is happening in todays world, it may very well go
down in price...

But that would mean that an 8GiB stick for a desktop would cost $80 just
for the ICs. I can find 8GiB of RAM for $60 and cheaper, I bet, if I
poked my nose around.
Or maybe desktops don't need ICs???

You write that as though being dismissive of DDR4. Why is DDR4 currently
unacceptable for one of your designs?

Well, I bought a 4GiB RK3399 SOC card fro firefly for $200.
Don't get me wrong, I love your effort, but I need RAM, CPU power,
lots of ports, and more screen landscape.

Hmm, maybe you should invent an OpenSource IC?

Sincerely,
David
