RAM shows different speeds in different programs.

[NIKNAIZ]

Hello,

I was just digging around the specs of my computer and decided to compare what each program shows, so here's what confuses me.

My RAM, in Task Manager it shows this:
http://prntscr.com/al8by2
1600MHz

In CPU-Z it is
http://prntscr.com/al8cjs
Shows 799MHz and some NB Frequency at 2097MHz.

In Speccy it shows this:

Brief information about installed chips:

So how exactly does this work? As I understood, both of those sticks are dual-channeled, which I'm not quite sure how it works.

If they're dual channel, does that mean that one can't operate if other one is removed? I understand that they both make up that 1600MHz as both are 800MHz, so 800*2=1600MHz.

Or, if I remove one, will it be 800MHz and that's it?

Am I able to install additional RAM without any interferences to both?

I already figured out my laptop runs RAM on 1.35V and is SO-DIMM DDR3, CL11.

Or do I need to buy a new ram kit?

If anyone can please briefly explain things mentioned and questions asked, you are very welcome.

I run Acer Aspire V Nitro 17 VN7-791G

Thanks.

Hi, DDR=double data rate (800x2 = 1600). Some programs, like CPU-Z, list the actual speed, instead of the effective one..
Your RAMs run at 1600 MHz (no matter if single or two RAM modules installed)..

Go by CPUZ it's correct.

All your ram is running at 799x2 = 1598 aka 1600mhz.

Yes but, can you please answer on other questions?

Can I also install another ram stick that runs on 1600MHz, 1.35V and CL11 as they're stats my current ram is running on? Without any problems because those both are dual channel? Sorry, I don't know this.

"So how exactly does this work? As I understood, both of those sticks are dual-channeled, which I'm not quite sure how it works."

The dual channel increases the transfer rate / bandwidth. No relation with RAMs speed

"If they're dual channel, does that mean that one can't operate if other one is removed?"
No, Single RAM will work as well.

"Am I able to install additional RAM without any interferences to both?"
It depends on the laptop hardware (if free slot/s available).

"Or do I need to buy a new ram kit?"
Why would you like to install new RAM kit?

Thanks, there are currently two slots taken (4gb+2gb), two free, total 4.
I plan on buying and installing

Except the one I will buy is 1.35V, not 1.5V as stated on Amazon.
Will it work together with those RAMs already installed?

Mixing ram is hit or miss , it may or may not boot with the new modules.

They might work. Another option: http://www.amazon.com/Upgrade-VN7-791G-77JJ-1600MHz-PC3L-12800-PARTS-QUICK/dp/B00OAHQAA8

Take also into account that, for dual channel, RAMs have to be similar.
