    1800+ running at 1.1ghz

    Ok guys i'm a little concerned just got my new budget system up and running basically a msi k7n2 delta board with the ultra 400 nforce2 chipset, running 512(256x2) of twinmos ddr 400 and my 1800xp Tb and using the nvidia system utility it's showing my cpu speed at 1152mhz this is at stock settings not even delved in to my bios yet , this is out of the box, nvidia system utilty is showing my details as.

    FSB:200
    Mem BUS: 400
    Multiplier: 11.5 and
    CPU: 1152

    am i wrong but shouldn't it be running at about 1.5gh if so what am i missing what settings would i need to tweek

    Thanks

    Atif

    p.s bios reading also gives this speed.

    Your fsb is set at 100mhz rather than 133mhz. You should have this setting in your bios....

    yup, look in bios. make sure you set the ratio thingy to equal, but for some reson ppl say 6:6 is best...
    if your 1800 is a recent tbred b it should clock quite far aswell
    twinmos ram is good and i expect yours can easly manage about 230fsb and the mobo shouldnt have much trouble upto that aswell..
    the nvidia system utility is crap so use the bios for chanign stuff

    Thanks mate i'll check it out, any reason why the nvidia sys utility is reporting fsb incorrectly and do you know of any good software that will allow me to keep an eye on things such as cpu temp, fsb setting , mem speed ect

    Thanks

    sorry silent just saw your reply now ignore above post, although the software for system monitering question still stands

    Ok i've set my FSB to 133 and set my mem to be insync with FSB and set ratio setting of 1:1 didn't have a setting of 6:6 on msi k7n2, nvidia system utility is now showing my fsb and mem bus running at 266mhz and cpu running at 1536mhz is this right ?

    thanks

    yup, 1536 is right , the XP chips have an 'XP Rating'

    an xp1800+ (1536mhz), is roughly the same perforamance as a PIV 1.8ghz..


    they just use the names for marketing reasons

    Thank you , sorry another question now, is it better to have my mem bus and fsb running in sync or was having my mem running at a higher rate out of sync with fsb better for performance.

    once again thanks

    ok another question , my mobo has a big sticker saying 400mhz fbs and my ram is ddr400 i understand this is really 200*2 to give the 400 rateing so if i uped my fsb to 200 will it boost my performance and keep my ram in sync, and do i need to change anything else to overclock ??

    Thank you

    OK, now you are delving into the realms of 'overclocking'
    First, you must understand that fsb x cpu multi = cpu speed.

    At the moment you have an fsb of 133 (DDR 266) and a multi of 11.5 giving you ~1530mhz cpu speed.

    Upping the overall fsb (Which controls everything, cpu, ram, graphics) will increase your total cpu speed aswell as your ram speed.

    So, if you go from 133 x 11.5 to 200 x 11.5 you will now be getting a cpu at 2.3ghz, which is likely to be unstable. This is where your cpu multiplier will come into place.

    If you find that 2.3ghz is unstable, you will need to lower the overall speed or increase the voltage (Not recommended for noobs). Aswell as decreasing the cpu speed you will be wanting to keep your ram at 200fsb (400 DDR) though, so you will need to lower your multiplier.

    Of course, if you don't want to 'overclock' your processor at all, you could just lower the multiplier so that it would be near to 1530mhz (7.5 multi). But, especially if the processor is tbred b, you should be able to find stability near the 2ghz mark. So you can adjust the multiplier to 10x and then you will be at 200 x 10 for the cpu, and 200 x 2 for the ram.

    And thats basically everything. Of course you could just adjust your fsb:ram ratio to async so your ram will be at 200 and the cpu at 133 but the performance is usually lower as the AthlonXP architecture runs better in sync (I don't know exactly why, but theres a load of guys on here that do ).

    Hope all that helps
