    Default 4 GB of DDR RAM

    hi, ive just brought another 2bg of RAM for my pc so i will have a total of 4gb when it gets here.
    But so far with any motherboard that i buy they tend to only like 2gb max.
    My current motherboard is a Gigabyte GA-K8N Pro SLi, It has a max of 4gb 4X1gb. Is there somthink that im missing, some settings on the motherboard i have to enable for it to use 4gb. All the RAM that ive got and bought are the same make and model so it has a better chance of working (Samsung 1gb DDR 3200 400mhz).
    This is the problem when i got over the 2gb's (on any motherboard that support 4gb) and try to boot, the motherboard will either continuesly beep or beep in a pattern. Ive tried to reset the BIOS....Nothing happened....Ive tested each ram by itself and they all work.
    Any ideas

    With Windows XP, 4GB is put to waste, it cannot use it effectively and you cannot mix two brands/types of RAM. (Aka Samsung and Corsair)

    You need to set the command rate in bios to 2T before adding the otehr 2GB in. Windows XP will use around 3-3.9GB of ram.

    What CPU are you using?
    GIgabyte GA-990FXA-UD3
    AMD FX8120 @ 4GHz
    Patriot 1866MHz EL series 2X4GB DDR3
    Powercolour HD 6970 2GB w/XFX 8800GT 512MB Hybrid PhysX
    Creative X-FI titanium HD w/Technics class A 300W amp and tower speakers
    PC P&C 500W PSU
    2TB Seagate
    Coolermaster 690II w/Corsair H100 tucked under the hood

    Its the timing of your memory. Look for it in the memory options in your BIOS.
    My System:
    -AMD Athlon 64 3200+ Manchester Em4 Revision
    -Abit KN8-ULTRA
    -X800GTO2 @ X850XT PE (16 pipelines)
    -1024MB PQI TURBO DDR 400 @ (2x512) Dual Channel
    -450W Heavy Duty Rosewill Powersupply
    -Samsung Syncmaster 940BF>>>NEW
    -Seagate 250GB 16MB cache (perpendicular recording) with NCQ...

    Yeah, with XP 64 bt you'll see all 4GB of ram too. You want to look for "1T/2T RAM TIMING" and set it to 2T. Here is a picture of your bios screen with the setting:

    You need to manually set that to 2T or you will have issues. Use 2 sticks to boot up and go into bios. Set it to 2T and then power down. Then install all 4 sticks and it should work fine.
