Just purchased Kingston 2gb kit (PC2-4200 CL4 240-Pin DIMM kit) for my computer which is the emachines t5082 model. I used the memory configuator and this is what it reccommended. It says that it would run in dual channel and that my computer supported dual channel. Well, the computer recognizes the full 2g memory, but only runs in single channel. Is there something I am doing wrong? Is there a Bios update?

Re: Unable to run in dual channel mode
Hello, Welcome to FixYa.
Currently there is no bios update for your system. In the course of operating my business I have seen dual channel RAM run in single channel as a result of the CPU in use. This should not be the case in your model though.
I would encourage you to speak with a Kingston rep to solve this problem as you are well within warranty.
Toll-Free:+1 (877) KINGSTON +1 (877) 546-4786 Here is the Contact Page for Kingston if you are outside the U.S.
They will be able to resolve your issue which has to be related to the RAM you purchased. Even though the memory configurator pointed you to this RAM, it may not be functioning correctly and should be replaced or upgraded to a more specific RAM model.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

I'm a bit confused....did you have all four of these in the ACER and are trying to put the 2x1GB into the Emachine? And that the 2x1 GB wouldn't work in the Emachine but they did in the ACER and that the 2x512 Acer cards worked in the emachine?
If that is what happened here is my best guess. The ACER MOBO will support 533/667/800 MHZ DDR2 RAM. The Emachine will only support 533 RAM. Iys possible the 2x1GB are either 667 or 800 MHZ and are not compatible with the Emachine but will work in the ACER.
If you are a "gamer" and you have 1GB of RAM, and you have Windows XP, you probably need more RAM.
If you are a "gamer" and you have 1GB of RAM, and you have Windows Vista or Windows 7, you DEFINITELY need more RAM.
Some motherboards support "dual-channel" mode, when you have 2 or 4 _IDENTICAL_ sticks of RAM. What happens is that each byte written to the RAM is "split" into 2 halves; one half is written to the 'A' stick of RAM, while, simultaneously, the other half is written to the 'B' stick of RAM. Obviously, this takes 4 "cycles" of the RAM, rather than taking 8 "cycles", if there was only one stick of RAM. So, your RAM seems to run at "double-speed".
So, when you buy more RAM, either try very hard to "match" your current 1GB stick of RAM, or purchase a "2GB dual-channel kit", or two "2GB dual-channel kits", to upgrade to 2GB (or 4GB) of RAM.
If your Intel motherboards model number is D102GGC2 you can run up to 2GB of memory.
Two 240-pin SDRAM Dual Inline Memory Module (DIMM) sockets,
533/400 MHz single channel DDR2 SDRAM interface
Designed to support up to 2 GB of system memory
Use one GB in each DIMM slot for the total of 1GB. (See manual link below.
(PC2-4200) correct 533MHz you can go up to 2GB max, they should be matching ...non buff, non registered, no ecc Modules must be installed in pairs for Dual Channel mode. This tell you what you need, I am not sure why. It would seem to me if they were equal in all aspects ...??? Hope this helps...please leave rating...thank you kindly
Memory Upgrade for eMachines eMachines
T5082 Computer, the eMachines eMachines T5082 Computer takes the
PC2-4200 DDR2 SDRAM DIMMs. Supports Dual Channel DDR2. Memory Type, and
comes installed with 512 MB (removable) of Memory. You can upgrade your
eMachines eMachines T5082 Computer to up to a maximum of 2.0 GB Memory,
the system has 2 sockets to install Memory, already with 512 MB
(removable) standard Memory installed. For best Computer performance
use the maximum amount of allowed Memory per slot for your Computer.
Choose the following Memory Upgrade for eMachines eMachines T5082 Computer.
as you can see from the information below there are different requirements for RAM to work stable in your system . Most importand are the RAM VOLTAGE , SPEED , and Configuration of chips. you will need to consult the manual for qualified RAM requirements. Some RAM will work but not very stable. make sure the voltage supplied by your system is enough for the RAM. If you are running DDR RAM in dual channel mode, the ram needs to be the same size also.DIMM modules for the HP computer must meet the following requirements
The number of pins on the DIMM must match the socket type.
DDR memory requires a 184-pin slot and 1.8 operating voltage.
DDR2 memory is not compatible with DDR1 memory and requires a 240-pin slot and 2.5 operating voltage.
Synchronous dynamic random access memory (SDRAM): Only use DDR type SDRAM memory if the computer came with DDR-SDRAM.
SO-DIMM modules for the HP computer must meet the following requirements
The number of pins on the DIMM must match the socket type.
SO-DIMM memory requires a 200-pin slot.
DDR2 SO-DIMMs are not compatible with DDR1 DIMM and DDR2 DIMM memory modules.
With a computer running at a system bus of 533 MHz or 667 MHz, use a PC2-4200 (DDR2 DIMM 533) type.
The following requirements must be met for the DDR memory to function in dual channel mode:
Same density (256MB, 512MB, etc.)
Same DRAM chip technology (x8 or x16)
All either single-sided or dual-sided
Matched in both Channel A and Channel B memory channels
