You forgot VRAM

[@chowgeorge6947]

@@star_t1 what about EDO Ram as the earlier Gene. Ram. LOL

[@jefflassek6988]

Great video, very easy to follow. Thanks for putting so much work into it along with all the editing necessary.

[@gnosis8142]

4 out of 5 points (1 point deduction for the intro music).

[@chromeinox]

I admire you effort in making your video more accessible by speaking in English. Thanks, it was very informative!

[@semprocarnage]

True, when I always search for anything informative there comes a nerd who has the title "explained in hindi"

[@dianec.2920]

Thank you so much! It will be great if you can make another video talking about the details of the DDR buses and operational timing requirements.

[@venkatasimham4729]

Awesome Explanation and Knowledge share! Cannot appreciate enough. Kudos to you!

[@karislee8292]

Well explained with simple words. Appreciate your help!

[@vd7046]

7:29 Internal RAM width is 64 bit wide and I/O bus width is doubled, there's slight error, apart from that Brilliant Video thank you

[@apview786]

Congratulations.. Quite simple explanation.. without any crap.. Keep it up..

[@dynashekar]

Precise and clear. Good effort

[@ealurikarthik]

Thank you very much for detailed information on DDR's

[@lwalida8905]

Thanks bro, simple and precise.

[@princesspuneta]

Why do I feel like there is some marketing trickery going on with these DDR SDRAM releases?

[@RAHULSINGH-wc9ht]

This video is very helpful ,Please make more video on DDR and LPDDR related to testing parameters

[@rattianaditamilan9366]

Wow. Excellent teaching. God bless you

[@Helal_Tech]

Very informative video. Thanks, my friend 😘 ❤

[@merkel83]

Great job. Thank You for much detailed information

[@iamsmartacus]

I found one thing in this video that was confusing. In the section on DDR4, you say that the I/O bus rate should be 4 times the internal clock rate (which is the same as for DDR3). But then in the table at the end of the video, it shows DDR4 having an I/O bus rate that is 8 times the internal clock rate. Is this an error?

[@iamsmartacus]

After doing some research on my own, it seems like your information on the DD4 RAM in the earlier part of the video is correct, but the entry for DDR4 in the table at the end has some wrong values. You might want to double check this.

[@mohammadfarmani2140]

Thank you for sharing this nice video. Do you know the exact technology node of each of these DRAM generations?

[@oskar2930]

this video was very helpful, thanks!!

[@aquaticsplashes]

so on ddr3 are you referring the clock frequency just as the external data bus or the system clock? Because I thought the ram had to be as fast or faster than the system clock or else the computer would crash? I do understand when ddr3 came about there were improvements in the input out put and the electrical system and ram buffers too not sure what a ram buffer is and or how they actually improved ddr3

[@GoogleUser-kv2hk]

Thank you for this video my friend :D

[@rejithavijay8963]

Simply presented Very iformative Thank you

[@aquaticsplashes]

I get the pc number is mtps times 8 but not how you calculated the mtps is that a given number in the manual or is that something you calculated?

[@arunanindian40]

Love your channel bro💝

[@guyarnaultmfoumbi8876]

Very instructive video, well done

[@aquaticsplashes]

for example on the data rate for ddr4 200 times 800 you get 1600 but 400 times 16000 shouldnt that be 64000? but you still got 3200 but you multiplied 800 times 4 and got 1600 but multiplied 1600 only by 2 why is that one multiplied differently?

[@poojachoudhari8646]

Nicely explained

[@duelcore477]

bro ddr3 sodimm means single channel or duel channel

[@whoami696]

I need to know the size of DDR in megabyte or gigabyte: ddr1=128 or 256 or 512 MB u know what i meant? ddr2 ddr3 ddr4

[@kishankumar-pn3tj]

Thanks for making such informative videos thanks alot

[@tusharpandeyst]

Thansk for information,,,may be new updated protocols needs to be added in new video

[@aquaticsplashes]

how is mtps calculated I'm not sure if I glossed over that part or if you added it but on ddr3 it cant be added the io frequency and internal clock to get that mtps

[@sparshsharma5210]

Hi The clock frequency mentioned here, is it the CPU clock frequency ??

[@ALLABOUTELECTRONICS]

Yes, it is the clock frequency of the memory controller, which is interacting with the RAM.

[@sunshine_shine]

2 correction: 1.dram on the basis of dimm...ddr2 voltage correction from 2.8 to 1.8 2. In last ,comparison table...ddr2--> bus clock replace 533.33 by 133.33

[@tariktahaozdogan7459]

Great explanation!! Thanks a lot...

[@vd7046]

Awesome Explainatory Video

[@kanchukommulapushpa3175]

Can we also make use of LDDR in desktop . But also , it makes low power consumption ...

[@hvision02]

Excellent information. Thanks!

[@RejinReneshan]

Weather DDR or SSDR which one is best for high performance laptops?

[@tranglomango]

So where can I buy some of that Dynamic Cream?

[@md.mostafakhan4529]

Can it be any more detailed? Thank you.

[@huskiehuskerson5300]

So ddr1 ddr2 ddr3 ddr4 are all Sdram. And they all are of DIMM module?

[@dhanushkumar6720]

what does 4-bit prefetch mean?

[@nukalasivammasivamma4002]

Tqq sir clear explanation ❤️

[@trevorcole460]

If a computer is using DDR3 SODIM, can it also use DDR3 SDRAM. I am looking at a Mac Mini and working out the best upgrade for it.

[@Muneeb.266]

I don't think so because SDRAM has DIMM packaging and it can't be placed on a SODIMM supported motherboard.

[@gtbite3629]

Can i mix and run 1.35V DDR3L and 1.5V DDR3 Ram together..if my MoBo support 1.5V each ?

[@bl4ckk]

Nice info. .thank u sir

[@Theultimatebohab7137]

I know he can't help it but boy this guy is hard to understand I feel it would help if you talked slower

[@sathwikkunduru5503]

i have a doubt!!! you have given maximum band width of SDRAM as= (100*64)/8=800 MB/s but 100*64=6400 bits and 1 byte=8 bits so 100*64/8 =800 bytes/s but not 800 MB/s

[@ALLABOUTELECTRONICS]

Here 100 refers 100 MHz clock frequency. I hope it will clear your doubt.

[@sathwikkunduru5503]

yeah got it dude

[@6OV420]

can you use ddr3 ram for every laptop??

[@jessymode]

sounds like the guy that keeps calling me pretending to be the government

[@sanjivrao4778]

hi when SDRAM and DRAM was implemented?

[@iamsmartacus]

According to what I saw when I looked it up, DRAM started being widely used in the early 1970s, and SDRAM was introduced in the 1990s.

[@prabhakardas4261]

Sir can you give a lecture based on microprocessor 8085?

[@ALLABOUTELECTRONICS]

Hey Prabhakar, yes I will make videos on microprocessor and micro controllers. But first I am going to make series of videos on Op-Amp and other topics. So, to be frank, I will not be able to give you the exact time frame.
