Do you have bad RAM? Bad ram memory symptom - Let's learn together

[@Shripii]

Bro,my laptop's screen is flickering like that too but much faster than this laptop and the pan is starting very high and it stops and starts stops and starts every 1 second and i was right,the RAM is broken!OMG I FOUND THE PROBLEM!!!!!I AM SO HAPPY!!!!GOOD THING THAT I ORDERED ALREADY A 8 GB RAM MODULE!!!!!!!!!!THANK YOU SO MUCH!!!!YOU GOT MY RESPECT!

[@laser-on-off]

It looks like a 3D printed laptop case. Good job Acer !

[@juanchizabaleta2405]

Excellent master class, fast and straight to the problem, thanks for sharing, your South American student, greetings.

[@charleshall376]

No worries... im sure someone was stumped by this... like you said, i would expect some beeps or blank screen... not power cycling. Ill keep this in mind if i run across a similar issue. Great content... thx for the video

[@micgg1072]

had this new computer and it would freeze in the bios. i thought it was the motherboard so i got a replacement motherboard. then it would still freeze in the bios. i had two sticks of ram and i just replaced one in the ram slot. it didnt freeze in the bios anymore but i couldnt use two ram slots. so i bought two new sticks of ram and everything worked fine. crazy how these computers do this.

[@evananderson8452]

You are great!! Excellent tutorial. I think you may have solved the problem with my old Compaq CQ 56. Once I find where I put the Laptop I'll follow your instructions.

[@PHONE-LAPTOP-REPAIR]

this is a patient lesson for me.....thanks again for the lesson

[@fx40000]

Hi @Electronics repair school. the simple laptops have problem recognizing the double row memory modules, always try with the single row ones as they are most likely compatible. Thank you for all the videos, helped me repair quite a few laptops and a tv. Mersi mult Sorin!

[@Dr.muthanna]

Thank you Sorin for a nice video

Your new find of no start up puter just saved me with mine. All my laptop would do was blink slow on the power button. looks like it was either one dead ram slot or bad ram. Thanks.

I have seen all kinds of weird issues from bad RAM, it is something I always suspect.

So how would you know if it’s the ram if the computer starts and everything

I like the way you rub your fingers across the ram pins lol

[@MrRvdbeek]

I do now it this problem . It is new for me. Normally the memory ram is never broken. You have long warranty on the ram memory because they normally never break. Sorin thank you for the great approach to finding the problem. It’s not a waste of time for us. BBQ 🍖 was great

[@rayofcreation3996]

Sorin I think you forgot to plug in the speaker cable you pulled off while removing the back cover. 😀

[@saltcityrepairs5121]

I had that same kind of issues before, with the laptops i am repairing, and indeed it always point out to the Ram fault... Sometimes eraser does the trick. 😀

[@joshuaemmanuel3378]

eraser?????? how?

[@saltcityrepairs5121]

@@joshuaemmanuel3378 you can clean the connector pins using eraser. Try to rub the pins to remove foreign dirt ( most of the time, thats the reason why ram reading gets faulty, because of dirt/dust) Gets the work done effectively.

Ram is partially broken not a dead ram. When pc starts the graphic needs ram to show picture (because it is integrated gpu), but with faulty ram it can loop or in the midle of starting windows when it needs more ram the system will crash.

[@ElectronicRepair.Serbia2023]

I had the same problem the board does not support RAM memory because it is DDR3 and to the newer board should go DDRL 3 Sorin Plase lock that Ram memory what you tacke aut put it in another laptop should work.

yup

Hi Sorin Enjoy your videos, very informative and down to earth. Just a quick question I have an dell inspiron 1525 board which does not come on and I have found a resistor that is getting really hot but I can’t find any information on what it’s value should be , From what I understand it normally has a three digit code on it but this just has 1.5 on it. I look forward to any help you can give me as I am a novice at this. Keep the videos coming .

I think you missed the part of plugging the speaker back in?

That what I thought.. 😂

[@Dragonfly32145]

I wanted to change the ram from an old computer to a new one but when i did the swap, and turned it on, only the fan started spinning fast and the screen would not load, so I put the old one back and now the laptop just starts the fan and doesn’t load the screen, what can I do?

PC3L(1.3 volt) ram is different from PC3(1.5 volt) thats why your first ram is not working in this laptop.i think so

[@ivanzsar]

PC3L Laptops do support PC3.. PC3 Laptops don't support PC3L..

[@Sylvain5947]

it does not depend on the number of ram on the bar? 1Rx8 or 2Rx8? Because I already had problems of compatibility with this difference but with the same reference (12800S)

[@georgedone7997]

Am acelasi model de laptop Acer Aspire, doar ca e argintiu. L-am cumparat defect (ecranul spart) de la cineva cu 40 de Euro, fara modulul de 4GB memorie si harddisk (altfel era 75 de euro) si desfacut complet in bucati de proprietarul dinainte care din cauza ca nu se pricepea a distrus niste conectori ZIF si niste cabluri plate. Am reusit sa schimb ecranul si sa-l fac doar touchpad-ul nu functioneaza inca, poate e defect sau cablul panglica e intrerupt din cauza excesului de forta a fostului proprietar. slava domnului ca nu a incercat sa-l monteze el la loc, era tipul de om care ar fi insurubat un surub lung pana iesea prin tastatura.

[@georgedone7997]

Ce voiam sa mentionez este ca e foarte pretentios cu memoria, cand l-am pornit prima data a mers cu un modul DDR3L de 2GB, apoi in configuratia final nu mai voia sa mearga cu module DDR3L de 4GB si 8GB care erau 100% bune si la viteza corecta (DDR3L 1600), pina la urma a acceptat o pereche de sodimm-uri Nanya.
