Finally an Indian that actually talks in English.
I hate it when youtuber put English title but speak in Hindi in videos. Farming views from US viewers
Not just U.S
He is Pakistani!
RIGHT!?
bro think they speak english only in us
@@masbaurit's an Indian channel.
Wow! we barely get actual technical videos on tech these days (cuz views are less). But they are really informative!!
dude seriously man, you explained each part well , I came here cause I wanted to know about extended ram/virtual RAM but sat through the whole video. The explanation you gave for clean pages and dirty pages -I saw what you did ,The subtle visual presentation of the topic even before you started to explain about it -4:00 -4:20 BRAVO!!!
What a incredible video man...like we need more of these...seriously...🙌
Zram with a good compression algorithm compress data into the same ram.
It create a ram disk in the ram to hold the compressed data for decompressing when needed. It does slow down phone when u use your internal storage as zswap. Ive allocated 4gb of my ram as zram to store the compressed data and it gave me better performance. It never swaps and compress data directly to internal your storage.
That was really techy but I understand now finally what's the thing. Love to Guiding Tech❤️🔥
Thank you, I was looking for a video like this. Well explained!! I understand more! xD
Great video! One of the few English speaking explanations of what rqm+ is on android. Thanks man!
this video has been uploaded for almost a year now. it's so detailed. and the guy speaks english very well 😊 kudos sir! thanks to this info of yours now I'll be turning my virtual ram off. 😊
Thank you for your great explanation... I came here just to know the advantage and disadvantage of it. This info really helpful 👍
This was very helpful, thank you for all the great info.
Also, great shirt, I love that album
Thank you for the very informative explanation of the Virtual Ram! I have never seen it before, and was a little confused when I seen the 'Ram Plus' in my Samsung s22+ settings.
I appreciate the vid, cheers mate!
Much love from Australia 🇦🇺
Thank you for this, you have explained this better than any of my teachers and friends. I dunno where you're from, but you definitely are an incredible teacher and I hope you keep doing this 🙌🏻❣️
I love this kind of technical videos we need more of this.
Custom roms users knows this from 2010 to 2012😂👏🏻truh
Right 😁😁 i m still using it
yeah but internal storage back then wasn't as fast as lpddr4 ram. Now, we are approaching that speed and thus it's being officially implemented
@Tamash Jyoti Neog who told u root can kill phone ???
I had only one phone which I bricked and now I'm not trying it again
@Tamash Jyoti Neog if it kill your phone then revive it
Super Video. Much appreciated. ❤️
Thanks for the info. Clicked like and subscribed 🤠
This is what I call quality content. Salutation to you sir.
Youve helped me understand a great deal, what a genius!
super indepth, thanks for your great work!
Perfectly Explained 🙌🙌🔥
Very nice explanation. I turned it off on my phone as I'm going to use this for 2-4 more years. I monthly change downloaded videos (30GB+) on my phone so I don't want another thing decreasing my storage's life span.
Great breakdown. Answered my question well.
Great video bro! Really helpful. By how much your device's life is affected?
Great explanation dude! Thank you
Thank you, really appreciate your valuable inputs
So does me changing my virtual from 2 gb to 4gb do anything for me? I often play games that require a lot of resources.
Superb... Please Make More video like This..
Very clear and interesting explanation. Thank you.
Great explanation!
U really deserve more......much more🔥🔥
oh dang there is no way to turn off RAM plus on samsung only can select 2/4/6/8 gb
if it often used how much it will affect the device?
What a great research and superb explanation..keep it up Varun 👍
Thanks
Your english is so good!
Nice video. Thank you ❤
Briefly explained ❤️
Thank you. That was helpful.
For virtual ram or pagfiles there is also one misconception. You have to set virtual ram or page files according to physical ram in your phone or PC. If you have 6 GB ram in your phone than you have to set ram plus or virtual ram or page files 6×1.5=9 so 9 GB you have to set. Whatever physical ram your have on phone or PC, you have to set virtual ram or pagefiles multiply by 1.5, in ram plus you can get only 8 GB which kind of fishy I find as lot of users has atleast 6GB version of android phones.
You have zero clue what you're talking about.
@@unsavedprogress1419 so true. And this can cause many unspected issue. Only dev knows how this works. I try tweaking and study about paging file until i realize that this is a mess.
Thanks to clear the v.ram concept.👍
Wow,that was a clear answer bro,thanks
Really liked you explanation 👍👍
So if i buy a fast memory card can i turn it on (virtual ram)?
Great video thanks for the advice
Thanks, I'm turning it down from 5gb to 2gb.. Or should I completely turn it off?
Thanks much appreciated 🙏 👍
My A52s 5G just got the update it says I have 4g of virtual ram I originally have 6gb
Great explanation 👍🏼
Nice explanation !
Hola buenas Tardes. ¿ Zram en Android, se puede instalar sin ser ROOT? . Consume mucha batería? . Gracias y felicitaciones
Impressive presentation, Sir.
Should I turn off extension for my Poco x3
basically if you dont need it just dont use it but if you gaming and it crash or lagging i need to active it?
Great video 😮
How much will it effect the lifespan?
bro u deserve millions subscribers
So i was looking for something to boost an old tablet and found usefulness for the new one
Thanks a lot! You rule!!
Thanks i understand now
Used to talk about this in primary school 25 years ago
Thanks for the info greatly helped! I game on my phone and turned it on thinking i should but now I can turn it back off....
We must lower or raise the ram for big games that needs fps? Nice vid
Thank you for teaching this❤️
I'm going to turn off virtual RAM extension on my realme gt 5g now 🙂
Why?
@@Sive.dot1 For live streaming & performance reasons. Real RAM in my opinion is better than virtual swap RAM
Does zram affect the cpu perf when gaming? I have updated my hot 10s to latest May patch(v410), and I noticed a sudden rise in heat, a minimal fps drop in gaming but not that noticeable, only on long term gaming, (prolly after 30mins)
Lol zram has nothing to do with cpu performance. If your cpu sucks or your system sucks then it SUCKS
Yeah encoding and decoding for zram will use cpu performance. Hence it will make your phone heated and battery will drop faster
@@kuroneko-_5570 yes it does😂
@@impeace1012 not exactly, the way Zram is implemented on android is different
Great info
We use Virtual Ram on Windows too in form of Pagefiles
Yep, that's true. I didn't mention it since Pagefiles are basically swapfiles which is kinda different from swap partitions. I can do a detailed video talking about the differences between swapfiles and swap partition if folks are interested! ✌✌
@@GuidingTechEnglish Yes please do it, also I wanna know wheather creating virtual RAM (in pagefiles) will affect the life of harddrive in Windows like it does in Android, I think it will right.. at least on some level..?
May confusions brought me here. About virtual ram from a newly released smart phone brand.
Thank you Sir, this is very informative.
This is fantastic Varun, you have put it down so well. 👏
arctic monkey fan here. awesome tee broski
Thank you brother
I knew it would take an Indian guy to explain all this to me ,thanks brother 🎉
Bro what is ramless screen.... because when I contacted realme support team they told that realme 7 pro has a ramless screen so they cannot update the customization of Always on Display.
Hi. Typically modern displays have their own flash memory (referred to RAM for the panel) which it uses to access data. This data is basically the pixels that need to be displayed, and much more. Traditional displays do not have a RAM of their own, and are thus called RAM-less displays. The issue here is that since the panel used on the Realme 7 Pro is RAM-less, it always needs to access the RAM of the phone. This brings the lock screen into an active state, which is why AOD can't function properly.
Realme India has promised an update on this with some software patches, so let's see if the company can figure out a way around this.
Hope that helps! Cheers! :)
@@GuidingTechEnglish hi i learned that i can use pagefile on Android without root
my pot lx 1 have 3gb physicall memory and 3 gb virtual i can use more apps same time and more fps in games
@@umutkayabal7087 how, teach me pls
My phone has 4gb ram but the ram is always full and the UI is always laggy.
So adding Virtual Ram will help?
Depends on your work. If you just use the virtual RAM for browser (storing tabs), it will help. If you use it for big games, it won't help, because the speed of the virtual RAM is as fast as the storage's speed, which is significantly slower than real RAM.
you just make it cristle clear
Full review of iqoo 7 bro before may 1st please
Bahi yes ya no ma batto ki increasing virtual ram is good or bad on android
Gracias. 👏
Does turning off memory extension (virtual ram) increase battery 🔋 life?
Possible because it doesn't need to access the internal storage all the time that cost battery reloading the app allthe time.
Thank you
I hv 4/128 android, so virtual ram is useful for me? Ciz it can extend to 6 gb ram
On 4gb ram it will definitely help, anything over 4gb, you might want to consider turning it off.
Clearly Explaned
Yeah but it's always on i can't turn it off on Android 12
Is there a way to turn this off???? I areadu have 12gb ram on my 256gb S22 Ultra
tldr, on or off pls ?
Really good video , for me I turn of zram bcuz I have 8 gb of ram ( in my opinion any phone above 6gb ram which is using a custom rom doesn't need zram )
Thankss
Well, i think we shouldn't use our devices internal storage as ram, if we really want to do that, we better purchase a powerful sdcard so when its lifespan ends, we can throw it and purchase a new one, thats a right thing according to me, we shouldn't end our phones internal storage lifespan too early😉
bruuuh nice video
finally I can download more ram
👍🔥🔥👍
Virtual Ram is basically a gimmick
Today we get 12 gb which is more than sufficient
In a way, yes. Does it give you more RAM? No. But does it give you more FREE RAM when you need it? Yes.
Companies are not very honest about this feature. Android knows how to manage memory, and depending on which phone you use, it should be optimized already. Ram extension is not all that grand, especially with flash memory's volatility.
Thanks I'll just keep it turned off. Have 12gb ram already. Had the option to add 7gb on oppo find X2. Great advice good explanation on how ram work's etc... 👍
Thank you for explaining why the extension ram was killing my phone.
I had problems with my phone, people told me it was because i turned on the extension (i had no full on idea how ram works) i turned it off and it's well now.
I looked you up to figure out why it was happening. From your explanation i understood that i was technically speeding up my phone's aging.
My question is will it lessen the lifespan of the ufs storage?
No
Yes
No and Yes 🙄
for thumbnail you should have put ram or scam
👍
I already deduced its reality just now but I want to listen to other people's take on this one.
10:45
LINUX ALSO USES PAGING
Resistor and cache memory more faster than Ram
Was getting ready to increase my virtual ram (RAM+) on my Samsung Galaxy Z Fold 4 from the default 4 GB to 6 GB, but I watched this video and I'll be leaving it at the default setting.
