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.

| Processor Spped | 2.8 GHz |
| Systm Bus Speed | 533 MHz |
| System Memory Speed | 333 MHz |
| L2 Cache RAM | 256 KB |
| Total Memory | 256 MB |
| Memory Mode | Single Channel |
| Memory Channel A Slot 0 | 256 MB (DDR333) |
| Memory Channel A Slot 1 | Not Installed |
| Memory Channel B Slot 0 | Not Installed |
| Memory Channel B Slot 1 | Not 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.
| Manufacturer | Gateway |
| Product Line | E Series |
| Model | E2300 (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 Memory | 256 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 http://www.crucial.com/kb/answer.aspx?qid=4251.
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 |
| PC2700U | 0430 |
| 256MB DDR 333MHz CL2.5 | |
| HYMD232646B8J-J AA-A | |
I put the following memory in the system:
Kingston Technology
Value RAM
KVR333/1GR
The module had a sticker on it with the following information:
| Kingston Technology |
KVR | |
| KVR333/1GR | ||
| 740617072662 | 2.5V | |
| 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 Version | BF86510A.15A.0080.P18 |
| Processor Type | Intel(R) Celeron(R) CPU |
| Processor Spped | 2.8 GHz |
| Systm Bus Speed | 533 MHz |
| System Memory Speed | 333 MHz |
| L2 Cache RAM | 256 KB |
| Total Memory | 1024 MB |
| Memory Mode | Single Channel |
| Memory Channel A Slot 0 | 1024 MB (DDR333) |
| Memory Channel A Slot 1 | Not Installed |
| Memory Channel B Slot 0 | Not Installed |
| Memory Channel B Slot 1 | Not 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.
