Memory for an HP G70-460US laptop

An HP laptop running the Microsoft Windows 10 operating system that I was using was performing poorly and when I checked the system's performance with the Windows Task Manager, I could see that the memory utilization was consistently high. So I decided to check on whether I could increase the memory in the system. A sticker on the underside of the laptop showed the model number to be G70-460US. I wondered whether I could also get the model number from a Windows Management Instrumentation Command-line (WMIC) command if the sticker was no longer present or was illegible, so I opened a command prompt window and checked to see what information I could get using the wmic csproduct get command.

Memory for a Dell Inspiron 570 PC

A user reported her Windows 10 system was running slowly. When I connected to the system remotely to check it after the user had left for the day and closed all the applications she had running, I found that the memory utilization was 78%. I knew the system was a Dell PC, but I didn't remember the model number. I was able to determine it was an Inspiron 570 by right-clicking on the Windows Start button and choosing System. Under "Device specifications," I saw "Inspiron 570". I also saw that the system had only 3 GB of memory installed.

Inspiron 570
Processor: AMD Athlon(tm) II X2 240 Processor 2.80 GHz
Installed RAM: 3.00 GB (2.75 GB usable)

Memory for a Gigabyte 970A-DS3P Motherboard

I needed to determine the amount of memory currently in a PC running the Windows 10 operating system and how much more memory could be added to the system in order to improve its performance. To determine how much memory could be added, since it was a custom-built PC, I needed to determine the motherboard in the system. I didn't want to disconnect every device attached to it and open it up, so an option is to use Windows Management Instrumentation Command-line (WMIC) commands to determine the motherboard manufacturer and model number. You can also use WMIC commands to obtain details about the memory already in a system.

Memory Upgrade for Gateway PC Model Number MFATXPN1 ESX 500S P04

I upgraded the memory in a Gateway PC model number MFATXPN1 ESX 500S P04 (that is the model number listed on the back of the computer). The system, which was running Windows XP Professional, had only 256 MB of memory installed.

The following memory module was already in the system:

MT8VDDT3264AG-265C4, PC2100U-25330-A1
US        BZABW72029   200303
256MB, DDR, 266MHz, CL2.5V

The BIOS memory information was as follows:

BIOS Settings
BIOS VersionRG84510A.15A.0021.P11
Processor TypeIntel (R) Pentium (R) 4
Processor Speed2 GHz
System Bus Speed400 MHz
System Memory Speed266 MHz
Cache RAM512 KB
Total Memory255 MB
Memory Bank 0256 MB (DDR 266)
Memory Bank 1Not Installed

I installed the following PNY memory module in the second of the two memory slots in the system.

333MHz / 266 MHz
OPTIMA&trade Memory

The following information was on a sticker on the module:

64WQD-T PO135492

The package had "MD0512SD1-333-BB" on it above the UPC. The UPC was 7 51492 34983 1.

When I booted into Windows and ran winver, it showed "Physical memory available to Windows: 784,176KB".

I ran a 30 minute test of the memory with Windows Memory Diagnostic Beta. No errors were found in the 3 passes of the diagnostic program that were run.

Memory Upgrade and Sound Card installation in Gateway E2300 PC

I upgraded the memory in a Gateway PC model number MATXHDS MDW E 2300 (that is the model number listed on the back of the computer; a sticker on the side of the computer lists the model number as E2300). The system, which was running Windows XP Professional, had only 256 MB of memory installed.

BIOS Utility - Main
BIOS VersionBF86510A.15A.0080.P18
Processor TypeIntel(R) Celeron(R) CPU
Processor Spped2.8 GHz
Systm Bus Speed533 MHz
System Memory Speed333 MHz
L2 Cache RAM256 KB
Total Memory256 MB
Memory ModeSingle Channel
  Memory Channel A Slot 0256 MB (DDR333)
  Memory Channel A Slot 1Not Installed
  Memory Channel B Slot 0Not Installed
  Memory Channel B Slot 1Not Installed

I also needed to install a sound card, since the on-board audio stopped working. I changed the BIOS settings for the on-board audio support from "enabled" to "disabled". The option is listed under Advanced then Peripheral Configuration in the BIOS Setup Utility.

I checked the Crucial Memory site for information on the memory that the system will support.

Product LineE Series
ModelE2300 (4 DIMM slots)

The Crucial Memory site providded the following information at Computer memory upgrades for Gateway E-2300 Series (4 DIMM Slots)

Maximum Memory:4096MB
Standard Memory256 or 512 removable
Slots: 4 (2 banks of 2)

Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

Each memory slot can hold DDR PC3200, DDR PC2700 with a maximum of 1 GB per slot.*

*Not to exceed manufacturer supported memory.

The Crucial Memory site also had the following series of questions and answers regarding memory for the system:

Q: Will my system recognize the maximum upgrade?

A: Possibly

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at

Q: What memory goes into my computer, and will a faster speed be backward-compatible?

A: DDR memory with support for DDR PC3200,DDR PC2700 speeds.

Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds. [DDR PC3200 and DDR PC2700 modules were listed below the statement]

Q: How much memory can my computer handle?

A: 4096MB

Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.

Q: Do I have to install matching pairs?

A: Yes

Your system requires that you install memory in pairs.

The system had a 256 MB memory module in Channel A DIMM0. That module had the following information on a sticker on it.:

Hynix KOREA 03
256MB DDR 333MHz CL2.5
HYMD232646B8J-J AA-A

I put the following memory in the system:

Kingston Technology
Value RAM

The module had a sticker on it with the following information:

Warranty Void if Removed

The Crucial Memory site indicated that memory must be installed in matching pairs, but I wasn't sure if that applied just to modules inserted in the same channel, i.e., I wasn't sure if I could install the 1 GB module in Channel B, since the 256 MB module was in channel A. I put the new module in Channel B DIMM0. When I powered on the system, I saw "1264MB System RAM" but then received the error message "Dual-channel operation requires identical paired DIMMs installed across both memory channels." I then tried the new 1 GB module in Channel A DIMM1. Again I saw "1264MB System RAM" and the same error message, so I removed the 256 MB module and moved the 1 GB module to Channel A DIMM0. This time when I powered on the system I saw "1008 System RAM" followed by "Keyboard Error" and then "Memory Size Decrease". I powered the system off and on and didn't see the keyboard or "memory size decrease" messages again, though the system did display "1008 System RAM" again.

When I checked the BIOS configuration, I saw the following:

BIOS Utility - Main
BIOS VersionBF86510A.15A.0080.P18
Processor TypeIntel(R) Celeron(R) CPU
Processor Spped2.8 GHz
Systm Bus Speed533 MHz
System Memory Speed333 MHz
L2 Cache RAM256 KB
Total Memory1024 MB
Memory ModeSingle Channel
  Memory Channel A Slot 01024 MB (DDR333)
  Memory Channel A Slot 1Not Installed
  Memory Channel B Slot 0Not Installed
  Memory Channel B Slot 1Not Installed

When I selected the Advancecd tab in the BIOS Setup Utility and then chose Video Configuration, I saw the following:

Video Configuration
Primary Video Adapter [AGP]
Frame Buffer Size [ 16MB]

Presumably, the remaining 16 MB of the 1024 MB module is being allocated to the frame buffer, which is why the system is reporting 1,008 MB during the Power-on Self-test (POST) process.

When I booted into Windows and ran winver, I saw "Physical memory available to Windows: 1,030,896 KB".

I had also installed a Dynex model DX-SC51 sound card in PCI slot 1 at the same time I installed the memory. When I checked on the sound card, Windows Media Player reported "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."

Under the Device Manager, I saw "Unknown device" listed under display adapters, but no new audio device listed. When I tried to install the Dynex driver, I saw the warning message "Undetermine Card! Please do not click cancel on device manager!" Clicking on OK there produced another warning message "OS not support!"

I opened the case and checked the sound card. I found it wasn't seated fully in its slot. I reseated the card. When I rebooted and logged in as the adminsitrator, the Found New Hardware Wizard appeared. I inserted the CD that came with the sound card. The wizard indicated it found a Multimedia Audio Controller, an Envy24 Family Audio Controller WDM. After the sotware was installed, I was able to play music files on the system and hear sound from the speakers.

I ran a memory test on the new memory module with Windows Memory Diagnostic Beta. I let the test run for an hour and 30 minutes. The diagnostic program completed 22 passes with no errors found.
