What does it say in msconfig under the boot tab - advanced options - maximum memory. Is the box checked or unchecked? What does it say for number of processors?

 

[sylvans]

it said 3072 but i can't tick to maximum as 40xxish , it returns to (0) when i press ok thx for rply

plus when i start my pc i press Del , at the Bios Screen , it read my memory as 3072 also


i install my ram as DDR2 1 DDR2 3 DDR2 2 hope u help me

 

[bassfisher6522]

Doe you have 3 sticks or 4 installed?

 

[sylvans]

3 sticks 1=2gb 2 every1 =1 gb all equals to 3 sticks of ram

You may want to check your motherboard manual for supported memory configurations. Like most motherboard manufacturer, Gigabyte probably recommends that the same brand, capacity, speed, chips are used. At times, Windows will not detect correctly, if the memory cards are mismatched...

 

[sylvans]

DDR2 DIMM sockets supporting up to 4 GB of system memory
Dual channel memory architecture
Support for DDR2 1066/800/667 MHz memory modules
Because of chipset limitations
*To avoid the system being unable to start or the memory being incorrectly detected, if only one memory module is to be installed, we suggest that you install it on the DDR2_1 or DDR2_3 socket.
*To install two memory modules, we suggest that you install them on the DDR2_1 and DDR2_3 sockets, when the DDR2_2 or DDR2_4 socket is populated with a DDR2 1066 MHz memory module, the memory speed will be downgraded to 800 MHz).
*when using FSB 1333 MHz CPU with populating all DIMM sockets, memory frequency will be reduced from the original, and system instability or incorrect detection of memory module may be occur.
(Please refer "Memory Support List" for memory support information)



GIGABYTE - Motherboard - Socket 775 - GA-EP31-DS3L (rev. 2.1)

EP31-Ds3L i think it supports >.< 4gb of ram

 

[sylvans]

the 2 sticks of ram are=2GB are : Apogee DDR2 667 1GB pc2 5300 and ,
the 1 stick of ram =2GB DDR2 800 i think not sure but is 2 Gb

This is why,

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 4 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.

so i have to remove 1 stick of ram , and go on 3 gb of ram only

thx for help

 

[sylvans]

1 last question , where should i install 1st in DDR2 1 the 2gb ram or the 1 gb ram , or it wont matter
i'll remove the other 1 gb ram , and stay with 3gb ram only
should i upgrade bios to Fdc , or it wont matter also


Intel Core™ 2 Duo E7500 2.93GHz 3MB Wolfdale 45nm R0 65W 1066 FC
giga byte did't upgrade it even , so should i keep it (Fc)?
