Three times 1024, minus 8, is 3064.
The "missing" 8MB has been "stolen" as "video-memory" for the built-in video-adapter.

Since 3192 minus 3064 is 128, only the first 128MB out of the 1024MB is available to Windows.

It's the "design-architecture" of the 32-bit version of Windows which is the problem; hence, there is a 64-bit version of Windows which _fully_ recognizes more than 3GB of RAM, if, of course, the motherboard and CPU support 64-bit functionality.

What's your problem?bit ix38 quad gt motherboard with 2 gig of ddr2 ram i want to add a 1 gig stick of more ram that ive bought how do i do this? thanks windows seven


Top view of motherboard, scroll down. (Thought you might also like to read the reviews, and Comments)

http://www.bit-tech.net/hardware/motherboards/2007/12/06/abit_ix38_quadgt/2

Motherboard User Manual,

http://www.theraptorpit.com/forum/index.php?/forum/124-abit-motherboard-tech-support-unofficial/

1) On the motherboard the Blue ram memory slot that is closest to the copper heatsink, is ram memory Slot 1.
Also known as DIMM 1.

Ram memory ALWAYS has to be in this ram memory slot.
The Processor reads ram memory Slot 1 first.

2) The Blue ram memory slots are Slot 1 (DIMM 1), and Slot 3.
(DIMM 3)
The Black ram memory slots are Slot 2 (DIMM 2), and Slot 4.
(DIMM 4)

To run Dual Channel ram memory, means there are two LIKE ram memory modules ('Stick'), and they are installed in the SAME channel.

This would mean to alike ram memory modules, in both Blue ram memory slots, or both Black ram memory slots.

Since the ram memory modules need to be alike, they are generally purchased from the same manufacturer, and are the same kind.

Running ram memory in a dual channel configuration, is supposed to increase ram memory 'speed', up to 30 percent.

This is Baloney!
May look good on paper, but in actual use in the field it's cr@p.
Actual performance increase is more like 1 to 2 percent.
This has been proven by Tom's Hardware, and many, many motherboards, ram memory, Processors, etc.

So you have 2GB of DDR2 Sdram, huh?
Is it just one 'stick' of ram memory, or are you referring to two 1GB sticks?

If the above holds true install them in Slot 1 and Slot 3.

If not, and it is a 2GB stick of ram memory, be sure it is installed in Slot 1 (DIMM 1)
Install the 1GB stick in Slot 2.

It isn't the same as the 2GB stick.
It is 1GB.
Does NOT go in a dual channel configuration.

(Catching all this? There is NO dual channel ram memory!

It is ram memory that is -> ALIKE, and used in a -> dual channel configuration.
Used in two separate ram memory slots, that support the dual channel configuration.

Sold with the advertising scheme of 'Dual Channel', but really just means the two ram memory modules, (Or four), are -> alike.

1) Same Voltage used
2) Same Ram Timings
3) Same Chip Configuration
4) Same size in amount
5) Same frequency rate ('Speed')

With ram memory in a dual channel configuration, the ram memory modules team up on the task.)

I have a Gateway 838GM. It has 4 slots for RAM. It came with 1/2 gig RAM (2 sticks, 256 Megs each). I tried installing new RAM- 2 sticks, 1 gig each. If I replace the original 2 sticks, the computer...


Here are the specifications of the Gateway 838GM: You will have to replace the existing memory with thesesettings only: The machine comes with: 512 MB = 256 MB (removable) + 256 MB PC3200DDR SDRAM DIMMs. Supports Dual Channel DDR Nowyou can only upgrade to 4.0 Gig total. I would recommend going to this link and order the correct memory foryour computer I use them quite a bit. http://www.memorystock.com/memory/Gateway838GM.html Rob

I have intel d845gvs1 motherboard with P4 2.4 ghz, Currently have 2 ram (512mb & 256 mb) how much further can i upgrade the ram, 1GB or 2GB also is the current combination of ram is right?


"Supports up to 2 GB of system memory with DIMMs utilizing 512 Mbit
technology DRAM devices"-intel

you can use 2 sticks of 1 gig apiece to get to 2 gigs of total memory, but you have to make sure that the ram sticks use "512Mbit " technology.

the 512Mbit technology refers to the arrangement of memory chips on the ram cards. a card which uses 64Mx8 (8 seperate memory chips of 64M apiece) would be appropriate.

"Nearly all motherboards only recognize 1 GB modules if they are low density 64M×8 modules. If high density 128M×4 1 GB modules are used, they most likely will not work."-wikipedia"

2 gig ram sticks


Not with Windows XP, because more than 3 gigs isn't useful. Many servers come with 8 or more and nearly any computer you configure at the major manufacturer's websites can be bought with 8 or more.

Problems with Foxconn 6100K8MA-RS Motherboard memory upgrade


This is an oldtime POST code memory error. Likely that ram is either installed wrong, bad RAM or the mobo doesn't like one of the memory sticks.

See http://www.computerhope.com/beep.htm.

You must count the beeps.

Switch sticks around in various combinations (2 gig in slot one, 1 gig in slot two, switch, try other stick, etc) and see if it is the memory or the motherboard.
