I installed 4gb extra ram(initially system had only 4gb). whenever I restart(not shutting down and starting) system, only system is using only 4gb. Both rams are working fine when I shut it down and starting. I installed CPU-Z to see which slot is working and surprisingly CPU-Z is showing both the rams but only they are working only in single channel.


device specifications:

model - Lenovo B40-80

windows version - 1809(17763.348)

Windows shows 8GB RAM installed but 4GB RAM is usable

Hi There,

I've just upgraded my pc from 4GB RAM to 8GB RAM. Windows seems to have detected this upgrade but why does it show as only 4GB RAM available. The following is what I have tried so far with no luck:

• I have tried the msconfig method on ensuring maximum memory is not checked.
• physically removed the new RAM and reinstalled it

Any thoughts/suggestions on how i can resolve this matter?

Thanks

 

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?

 

Windows 10 using 4GB reserved RAM

I checked and nothing was checked off. this was a step I tried several times. and still same results. I am baffled to be honest. I would think if the RAM slot was non functional or damaged in some way, windows would not read the fact there are 8GB installed,
nor would other apps show the RAM stats, maybe I'm wrong? it seems strange though the BIOS only reads 4GB physical (which windows indicates yet indicates also the other 4GB are "hardware reserved" Ive removed all the hardware other than the 2 extra SATA drives
I have installed on system, and nothing changed. Could it be somehow RAM is being allocated to these 2 Drives? I would of thought removing my Video card and just running the onboard would of shown results 100% different than I got, which was it added 500MB
to the existing 4GB .. I'm really dumbfounded here.
