2 x 1GB Samsung PC2100 appearing as just 1GB (2 X 512MB)
Hello, I tried upgrading to 2 x 1GB DDR Samsung PC 2100 266Mhz DIMMs (from 2 x 256MB SIMMs), but both the BIOS and Windows see only 2 x 512MB. Before buying the new memory I tried 2 x 512MB Samsung DIMMs and all worked well. The MoBo manual says that it can take 2GB. Is there a solution for this, or is it just that the memory is incompatible? Here are some specs for the new RAM GENERAL SPECIFICATIONS

I see you're point. I know this, you can not run "more than" 512MB in any DIMM slot. That is shown at the bottom of page 10 & the top of page 11. You can not run both types of memory at the same time, even though the chart looks like you could. The description term on page 10, states; Users only can install either 168-pin SDRAM Module or 184-pin DDR DRAM Module at one time. (You can't run both). You can run 4x512MB in all banks using184-pin DDR SDRAM. Or you can run 4x512MB in all banks of 168-pin SDRAMs. Total of 2GB.
So you can not run 1GB of memory in any bank.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Hi Steve Handel II, Yes that machine has limited RAM capacity, that model can go up to 1GB of RAM total (2x512MB DIMMs.) It takes DDR PC2700, CL=2.5 unbuffered, non-ECC DDR333 memory chips. The good news is you can get them for $10-$20 most anywhere. Like HERE
Hi, Memory Upgrade for Sony VAIO
PCG-K35 Laptop, the Sony VAIO PCG-K35 Laptop takes the PC2100 DDR SDRAM
SODIMMs Memory Type, and comes installed with 512 MB = 256 MB
(removable) + 256 MB (removable) of Memory. You can upgrade your
Sony VAIO PCG-K35 Laptop to up to a maximum of 1.0 GB Memory, the
system has 2 sockets to install Memory, already with 512 MB = 256 MB
(removable) + 256 MB (removable) standard Memory installed. For best
Laptop performance use the maximum amount of allowed Memory per slot
for your Laptop.
From Asus tech:
3 184-pin DIMM slots for PC1600/PC2100 DDR SDRAM Supports up to 2GB memory No ECC supportThis is only compatible RAM so make sure your new chip is PC1600 or PC2100. If you mis the 2 it the faster RAM will run at the slower chip speed. Hope this helps.
Your post indicating that you are moving up from SDRAM to DDRAM shows that your motherboard is capable of either type (having both type of slots) and therefore would have been a few years old. Having said this, then your MB would have the very early version/compatibility of DDRAMs where/when 512 then was the highest readily available memory.
As most Taiwan manufacturers, Jetway would be publishing specs that are a bit just over rated in terms of their product performance unlike Asus, ABit, AOpen. Additionally, most have been known to be using the same manual for several versions of the motherboard. A similar looking motherboard can come in several versions such as those with internal video while another is an AGP slot; one versions may or may not have built-in Ethernet port. In the same token, a version may have 2 X SDRAM slots + 2 DDRAM slots or 4 X SDRAMs or 4 X DDRAMs. Again, we are talking of the same model number of the motherboard but different versions/revisions.
2 G would be right for the 4 X memory slots versions (at 4 X 512) but since you have the 2 + 2 (2 SDRAM + 2 DDRAM), maximum would only be 1 Gb (2 X 512).
Hope this be of additional help/idea. Pls post back how things turned up or should you need additional information.
You can use only DDR 266Mhz dimms maximum upto 2 GB. i.e. one DIMMS of 266Mhz of 2GB or two of 1GB each. For more details read bellow:
System Memory Features
The D845GBV board provide the following memory features:
Two DIMM sockets supporting 2.5 V (only) 184-pin 200/266 MHz Double Data Rate (DDR) SDRAM DIMMs with gold-plated contacts Unbuffered non-ECC DIMMs only Maximum total system memory: 2 GB; minimum total system memory: 64 MB Serial Presence Detect (SPD) DIMMs only Suspend to RAM
CAUTION: Do not use ECC DIMMs with the D845GBV board. Using ECC DIMMs could damage the Desktop Board.
