Question about reading memory (ram) info

by JP Bill / March 22, 2007 12:55 PM PDT

I am looking to buy some ram, so I wanted to find all I could about the installed memory on my machine. (more than just the physical memory) to determine what I needed..

Found this cpuid

It claims my memory is Samsung and lists the part number and other info.

Is it actually reading my memory info or is it reading the processor and the motherboard, and finding the model number of the computer and then telling me which manufacturer could/should have been used for my computer.

Since I don't know what is in my computer, because I didn't look, has anyone used this program to check their memory?

Was its information correct?

Each ram stick has a small area called spd.

Kind of an info block that defines the stick.

Perhaps that's what cpuid is reading.

These folks have a memory scanner.

Run it and compare the results.

cpu-z is accurate

on the memory tab it shows what your memory is configured for and the timings it is actually running at. on the spd tab, it shows the memory manufacturer and the recommended timings.

Be aware that it highly unlikely that you MUST use Samsung.

Just go to http://www.crucial.com. Give them info about your system and they'll tell you types and maximum sixe per slot and total maximum for the system.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
