Hello,

I got a computer I want to expand its memory. All I know is that it has 2Mb memory. What else should I find out (and how do I find out...) in order to add another 2Mb ?

I tried dxdiag and Aida64, but there was no info I could understand, or basic info I'm aware of (like card's bus speed in Mhz).

Thank you !

Your best solution would be to find an additional 2GB or however much more you're looking for with the same exact timings and speed. As I mentioned earlier, you could technically get any DDR2 memory 800MHz and above and it would work, but whoever you talked to is right in a sense. It MAY cause issues. Are they so frequent that I wouldn't recommend getting a different brand? Absolutely not. With lower speed memory like you have, the timings are almost universal.

Search for DDR2-800MHz memory and see if you can find one that matches your timings. Commonly, DDR2-800MHz memory will come in CAS 5 which is what you have. Most of that memory is 5-5-5-15 like you have. There are some out there with CAS 4 and 6, but most commonly 5...

2MB? Is the computer from 1985? It's more likely you have 2GB. You need to find out the architecture and speed. Architecture would be DDR, DDR2, or DDR3. This is also written as PC, PC2, or PC3. This is followed by speed. 667MHz, 800MHz, or the like. If you look directly on the memory module, you should find a sticker with this information on it. It's most often written as "PC2-800" or "PC3-12800" or something like that. It may also be written straightforward as "DDR2 800MHz" or "DDR3 1600MHz." You want to try to match what you have. You can get faster memory and it will clock itself down to the speed of the other memory. For example, if you currently have 800MHz memory, and buy an extra 2GB of 1066MHz memory, the 1066MHz memory will slow itself down and run at 800MHz in order to match what you have.

I managed to get this out AIDA, there's also this thing with the X-X-X-X about the memory)

Motherboard:
CPU Type DualCore Intel Pentium E6300, 2800 MHz (10.5 x 267)
Motherboard Name MSI G41M4 (MS-7592) (2 PCI, 1 PCI-E x16, 2 DDR2 DIMM, Audio, Video, LAN)
Motherboard Chipset Intel Eaglelake G41
System Memory 2048 MB (DDR2-800 DDR2 SDRAM)
DIMM1: 2048738050LOC 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-4-4-10 @ 266 MHz) (3-3-3-8 @ 200 MHz)

Chipset Properties:
Motherboard Chipset Intel Eaglelake G41
Memory Timings 5-5-5-15 (CL-RCD-RP-RAS)
Command Rate (CR) 2T
DIMM1: 2048738050LOC 2 GB DDR2-800 DDR2 SDRAM (5-5-5-15 @ 400 MHz) (4-4-4-10 @ 266 MHz) (3-3-3-8 @ 200 MHz)

[ DIMM1: 2048738050LOC ]

Memory Module Properties:
Module Name 2048738050LOC
Serial Number None
Module Size 2 GB (2 ranks, 8 banks)
Module Type Unbuffered DIMM
Memory Type DDR2 SDRAM
Memory Speed DDR2-800 (400 MHz)
Module Width 64 bit
Module Voltage SSTL 1.8
Error Detection Method None
Refresh Rate Reduced (7.8 us), Self-Refresh

Memory Timings:
@ 400 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 23-51-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
@ 266 MHz 4-4-4-10 (CL-RCD-RP-RAS) / 16-34-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)
@ 200 MHz 3-3-3-8 (CL-RCD-RP-RAS) / 12-26-2-3-2-2 (RC-RFC-RRD-WR-WTR-RTP)



Do I have DDR2 800 MHZ ? What kind of timings should I ask for ?

Thanks again

I found I have a CEON 2GB 800 Mhz mem. Someone told me that I should use the exact memory and brand to avoid trouble. Problem is, I can't find similar CEON memory card. Is there any other memory that is compatible ?

Thank you !

Most of that memory is 5-5-5-15 like you have. There are some out there with CAS 4 and 6, but most commonly 5. Just make sure you get memory that matches the voltage as well. Again, most of the DDR2-800MHz modules are going to 1.8V which is what you have, so it shouldn't be an issue.
