    I have an MSI KT4V (MS-6712) with a Barton 2800+ @ 166 x 12.5
    I have 2 sticks of identical DDR400 RAM running at 333mhz (along with the CPU of course).
    Is there a way to get my FSB up to 400 so I can run my DDR at full speed, or is this 2800 simply not capable of a 200FSB?

    I find that my RAM runs at the full 400mhz when I use the BIOS default of 12.5x100, which is don't understand.
    I tried setting 10.00 x 200mhz and when I rebooted all I was met with was no monitor signal (orange light) so obviously I screwed up, I cleared the CMOS and I'm back running at 166mhz.

    If you have sufficient cooling I dont see why it wouldn't. My 3000 Barton was a 333 mhz core and it ran there just long enough to start up the system. Try lowering the multi and raise the vcore and bus first to see if the core is capable of 200 memory speed. If it works then you can try for max and work on cooling.

    Hmm ok. But is there a easier way to reset the BIOS apart from using the jumper on the mobo (I have to take out my PCI cards and then reseat the buggers for that :O ) if it screws up again?

    you can also reset it by taking the battery out

    and yes, a 2800 is capable of running 200fsb, mine is an athlonxp-m, which originally ran at 133fsb, and it can handle 200 easily, but you may need to up the core voltage to do so

    I use a small pair of hemostats to reach in between the cards as mine are also very much in the way of the jumper. As always make sure to disconnect power and push the power button to drain the capacitors before poking around in there with a conductive tool.

    Right, I set the FSB to 200 (and left the DDR RAM clock to Auto, as it sets it accordingly to my FSB anyway) and my multiplier to 6.0 to keep the actual ghz low, just to test if it would run at 200. Black screen on boot up again? What am I doing wrong!

    The wrong think is your Via KT400. I menage to OC the boart of my friend, with the same chipset but ASUS brand, to maximum to 186MHz FSB but at 183MHz is stable.

    Key Features of KT400
    Supports AMD Athlon™ XP processors
    » 200/266/333MHz FSB settings
    » 200/266/333MHz System bus settings
    » Support for AGP 2X/4X/8X
    » Supports up to 4.0GB DDR200/266/333SDRAM
    » 8X V-Link 533MB/s high bandwidth North/South Bridge interconnect
    » Support for Advanced Communications Riser (ACR) Card Standard
    » Integrated 6 channel Surround Sound AC-97 Audio
    » Integrated MC-97 Modem
    » Integrated 10/100 Ethernet MAC
    » Support for ATA 33/66/100/133
    » Support for USB 2.0, 6 USB ports, UHCI compliant
    » Advanced power management capabilities including ACPI/OnNow
    » 664-pin BGA VT8368 North Bridge

    Hmm but with 186mhz, I can't run my ram at 400mhz though, can I? Thats only 372mhz.

    You could if the chipset was KT400A, with this one - you can not (I think). But you could try in asinchron mode. Since it is not nforce chip - it will not have hit in the performance.

    Darn :( I guess I'll just wait till I get a new AM2 comp and forget this old crap.
    Just another 2 ... grueling years of 25fps in HL2 on low :(

    something sounds very wrong there, even my old 2100+ with a 9800 pro could manage 40-50fps on medium-high (depending on resolution)

    Maybe I exaggerated a little bit. I get a perfectly fine stable fps of 35-49 looking directly at the ground or at a wall, looking at a bunch of enemies it drops below 35. Games are so much funner to play when they're smooth and dont stutter etc :(
    This old Scket A technology is pretty old and there's no real point in putting money into it.

    i have a KT4AV-L with a 2800+ Barton and a 6600GT its still not a bad system and holds up pretty well, i just use it as a server now though, its pointless trying to overclock with this board though as it has no PCI lock etc, This thing will play BF2 pretty solid at medium settings, i suggest you upgrade to 1GB of ram and games should run smoother

    Forgive me for not keeping my forum profile hardware info up to date. I have 2 sticks of DDR400 RAM (running at DDR333 because that is the obvious limit of this board).

    Is a 7900GT 512MB worth the extra money? It's still cheaper than the next model up.

    Take a second hand Abit NF7 first for a 30-50$ and sell yours and then think for a graphic card. So you can run you Barton at around 2400MHz, in dual channel and stable. Nobody know how this 7900GT will work in your system. As I remember the AGP speed is not locked to 66MHz on KT400. Take a care of the FSB/AGP dividers. So.. when you OC the FSB you also OC the AGP and some cards do not like to be more than 83MHz and other even more than 66MHz.

    I was just planning to get a 7900GT in my NEW PC with a new mobo, case, CPU etc...

    Second hand Socket A motherboards are really hard to find in Australia.
