My motherboard has four 1GB DDR modules installed, yet it is only recognizing 2 GB. How can i get it to use all 4 gbs?

Hello here is the homepage:

http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?CategoryID=1&DetailID=436&DetailName=Feature&MenuID=24&LanID=0

Your mainboard supports:

2 DDR DIMMs
Supports DDR266 / DDR200
Max. 2GB

You can easy add 2, 1gb modules.

I recommend 2 gb ram.

Good luck

You're board can handel; DDR SDRAM up to 200 or 266MHz DDR SDRAM memory module. Accommodates two "unbuffered", 2.5V 184-pin slots. Each slot supports up to 1 GB with a total maximum capacity of 2 GB. Return the Kingston memory you have installed if it is less than a year old. They should allow you to trade up to the MB's supported memory.
Two reach the MB's max memmory of 2GB. Buy two Kingston DIMMS of, "unbuffered", 2.5V 184-pin
DIMMs. Here is one site that sells Kingston memory;

If you decide to search for you're self, use this as the basis for the correct model: Module - KVR266X64C2

Hi. The amount of memory that can be installed is limited by the motherboard, not the CPU. That being said, the motherboard you have listed will take the following memory:

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

A number of things could be happening.

Correct memory type?

The mainboard provides four 240-pin 1.8 volt non-ECC DDRII DIMMs.

DDRII modules are not interchangeable with DDR and the DDRII standard is not backwards compatible. You should always install DDRII memory modules in the DDRII DIMMs and DDR memory modules in the DDR DIMMs.
- In dual-channel mode, make sure that you install memory modules of the same type and density in different channel DDR DIMMs.

For more information on compatible components, please visit http://www.msi.com.tw/

Here's a link to a manual for your motherboard: http://static.tigerdirect.com/pdf/MSI_K9N4_SLI_Series_Manual.pdf

The motherboard does not support 1 GB modules; 512 MB is the maximum the motherboard will recognize. Usually, the computer won't even work if the memory isn't supported but in this case it does.

Thanks and please remember to give this a thumbs up rating.

From the Dell specifications page for Dimension 4600:
Memory
Architecture
Dual Channel DDR SDRAM
Memory connectors
Four
Memory capacities
128-, 256-, 512-MB or 1-GB
Minimum memory
128-MB DDR SDRAM
NOTE: Between 32 and 64 MB of system memory may be allocated to support graphics, depending on system memory size and other factors.
Maximum memory
4 GB
Memory type
PC2700 (333-MHz) or PC3200 (400-MHz) DDR SDRAM
(non-ECC)

You do not say what memory you are trying to install.

The ASUS P4S800D motherboard has four memory slots that hold DDR PC2700 or DDR PC3200 with a maximum of 1GB per slot, so the installed maximum is 4GB.

DDR memory is generally available in 128MB, 256MB, 512MB and 1GB modules. If you already have memory installed, it must be at least 128MB so you cannot add modules to 'bring memory to 128'.

Either you have a different motherboard and posted in the wrong section, your memory calculations are wrong, or you have used older PC-133,PC-100 or PC-66 memory instead of DDR. The last is unlikely as older SDRAM has two notches and won't physically fit into a DDR slot that only has one notch.

Please re-post with the specific motherboard model just to confirm and a list of the memory modules you are trying to use.

The board supports upto 4 GB RAM. PC3200 RAM is supported.

1. Reset CMOS settings by CMOS jumper.

2. Try updating BIOS of your motherboard from :

RAM has to be

Four 184-pin DDR DIMM sockets

Supports PC3200 (400 MHz) /PC2700 (333 MHz) / PC2100 (266 MHz) DDR DIMM type

Maximum HP/Compaq approved memory module is 1 GB

Maximum HP/Compaq approved memory is 4 GBIt has to be the same.


• If you are replacing a memory module, put the
new memory module in the same memory slot
from which the old memory was removed.
Or
• If you are adding a memory module, install the
new module into the socket nearest the
preinstalled module, and install additional
modules in the next available sockets

Your instruction manual for the mother board should have this, however, with dual-channel motherboards, you will want to fill the same colored slots together if you have dual-channel capable memory, otherwise you'll want to fill in the off-colored slots first.  ASUS has it's manuals online, so if you've lost yours you should be able to download a pdf of it from their website.
