Like OnePlus 5
is the 8GB version = 4GB + 4GB of RAM ? or Single 8GB ?
and 6GB version, is it 2GB + 4GB ? or single 6GB ?
the qualcomm 835 page does not tell any useful-related info to this question
neither OnePlus 5 specs page
they only show:
Memory Speed
1866MHz
Memory Type
Dual-Channel
LPDDR4x
I don't understand your question... it has 6GB or 8GB of RAM, what difference does it make if it's two 4GB chips or 8GB (or four 2GB chips), or a 2GB and 4GB or a single 6GB chip (or three 2GB chips)? If you are referring to the "dual-channel" thing, then you should look into what that technology is, but it could easily be implemented in a single chip if it was specifically designed for that. Mobiles rarely use "off the shelf" components and are chips are often specifically designed for applications as needed.
This is pretty much off topic for this area anyway, probably more appropriate to ask in the OnePlus 5 group.

I recently purchased a Zenfone 2 Laser from Amazon. I know there are two base models, a 2Gb of RAM with a Snapdragon 410, and a 3gb of RAM Snapdragon 615 Chipset phone. The 3GB version comes in a 16GB and 32GB model. From what the details on Amazon listed I have the 3GB RAM, 16gb storage version of the 615. Doing a quick check through the app Droid Info (I know there are better ones, just first that popped up), I noticed that it lists the chipset as the MSM 8939/Snapdragon 615, but it has a clock of 1.5ghz, and it also lists the board as a msm8916, which is a Snapdragon 410.
So which is it? The phone is listed as having 8 cores as well. So I'm inclined to think it is the 615 not the 410.
Thoughts?
Mine mentions this as well and it was a little confusing but there are 8 cores so I believe Asus may have used the same boards with different processors attached.
Just seen that.
They advertise the compact as a 2GB RAM device, knowing that they only deliver 1,8 GB.
Anyone else seen that before?
I do not think it s a way to free up to full 2GB as advertised?
Other brands deliver 2GB if they tell their devices have, why not so z5 compact?

Where's the source on what you're talking about? The RAM is always going to be used up by something - the OS, launcher, etc. You're not going to turn the phone on and have exactly 2GB of RAM available.
Sure, but it says 1,4 out of 1,8 used, 3xx free.
That means Limit is 1,8 as shown under Memory, not 2 as advertised. Never noticed that on a phone before.
As soon as the device is running memory is used, but it should say out of 2,0 not 1,8?

you're a little late to the party

Also - not sure why you'd want to specifically blame Sony for this
Coming from the technical, developer background:
you have to consider that device drivers also eat up quite some memory/storage (best example: the Galaxy S, GT-i9000: 512 MB advertised, at best 300 [384 at best] available)
it's only the device drivers, it's the kernel (system) itself that also needs memory
so you'd basically have to advertise e.g. 2 GB but plug in 3 or even 4 GB to have full access for e.g. apps
All companies define a gigabyte to be 1000MB, and a megabyte to be 1000kb, etc etc. In reality it's 1024KB per MB, and 1024MB per GB.
You never fully get 2GB, just check your computer eg. your hardrive might be 1tb big, but in reality its only somewhat over 900gb? 16gb ram might only be 15.9 gb!
Well, nice, not sure since when vienna is germany?

derailing the topic like a pro
Home Country vs. Service Provider vs. City
you'd know that if you had taken a look at your own profile
(I moved back some time ago)
Thanks for the notice though
The topic is...that in Windows the full RAM without any convertings of bits and bytes is shown.
Only Hard Disks have that "exchange" from 2TB to 1,8 e.g.
So I was not awaiting that on mobile RAM too.
Really ?
I gotta take a look next time I booted into Windows,
Android sort of is Unix, Linux - so that is more to be expected
yep
BIOS: 3096MB a 4GB Bar
Windows too
But I got an explanation somewhere else as smartphones use flash memorys equal to SSDs so its the same 1000 isnt 1024...thing there )

3096MB ?
that looks more like a 32bit OS limitation though

Plus, on android some ram is reserved by GPU. Unlike dedicated graphic card on PC/Mac which got their owned ram but our GPU shared with system memory.
Same thing as onboard GPU on desktop systems so?
Well 3096 per slot, using several 4GB bars, no 32 bit limitation)
Hi
just ran CpuZ on my Exynos model and it indicates:
Total Ram 3580MB (1190 available at the time of the test)
Internal storage 24.86GB
I know about the 1000 vs 1024 story, but even with that in mind, those figures look quiet far from the numbers announced (4GB & 32GB) by Samsung???

I'd also like an explanation. I've no doubt there are 4gb of memory soldered onto the motherboard, but I'd like to know why only 3.5gb are reported available.
In 32-bit days, before Lollipop and ArmV8 architecture, devices always reported a maximum of 3.5gb available because that was all that could be used on a 32-bit system. I'm wondering if this ram reporting issue is due to some kind of 32-bit limitation on our 64-bit devices.
If anyone really knows the technical reasons for this, I'd like to understand what's going on, just to satisfy my curiosity.

Is some of the RAM reserved for the graphics chip, like a PC has system RAM and video RAM for the GPU?
Some of the RAM around 512mb is allocated to the GPU, and for the storage, 8gb is used for android system partition
Is it possible to develop a ROM for the G4 and G4 Plus with arm64 libraries since the Snapdragon 617 is an arm64 SoC?
You don't have drivers for that (camera for example).
Also, it's stupid.
I had the Asus Zenfone Laser 2 - S615, 4GB of RAM. It had the 64 bit Android. Well, all the apps took much more space in the memory (1.5x times more in average) - this is in both storage (internal SD) and in the actual RAM. So sure, I could "see" the full 4GB of memory, but the actual "free" memory was less (or at best equal) than what I have now in Moto G4 Plus.
There was no speed advantage when tested, compared with other S615 chips. That's normal since on both S615 and S617 the data bus is 32 bit only.
Only the S810 and higher have a data bus of 64 bit, but still, without at least 6GB of RAM, the 64 bit OS makes no sense...
and motorola sources are 32bits
hi , I am building an extreme desktop computer and I have an i9 13900ks. I want to know what model of ram memory, mhz, cl, ns, I have to install, so as not to have a bottleneck between the microprocessor and the ram memory, I can buy at any price
To get the most out of your Intel Core i9-13900KS processor, you should look for DDR5 RAM with a high frequency and low latency.
Since DDR5 is a new technology, there are not many options available on the market yet. However, you should aim for a RAM frequency of at least 4800MHz and a CAS latency (CL) of 34 or lower.
Some manufacturers, such as Kingston, are already offering DDR5 RAM with speeds of up to 6000MHz, which would be even better for your build. However, keep in mind that these high-speed DDR5 RAM modules are currently quite expensive.
In terms of timing, you should aim for a memory module with a clock cycle time (tCK) of 16.67 nanoseconds (ns) or lower. This will ensure that your RAM is fast enough to keep up with your processor.
Finally, it's important to ensure that your motherboard is compatible with DDR5 RAM. The Gigabyte Z690 AORUS ELITE AX DDR5 motherboard you mentioned in your previous question is compatible with DDR5 RAM, so you should be good to go in that regard.
The ddr4 memories are the lowest latency of CL 7, on the other hand, the ddr5 has the minimum CL 10, the ddr5 will be faster but it has a lot of latency, the ddr4 has more performance
to know the total power of the power source I have to add all the hardware to know the total watts
