    i have been pondering for months about whether or not to get a new PSU....rite now i have a generic 300W running a steaming c/c athlon box...and in my o/c endeavours i have noticed something quite strange....i've hit a brock wall withy my cpu o/c and this is the result of it....

    1.my cpu is stuck at 1.70ghz @ 148fsb...
    2. i don;t think the cpu is the limiting factor as i can lower vcore voltage and it's still stable
    3. it's not my internal modem limiting my fsb o/c..bcos i have tried taking it out with the same results..btw apart from my soundcard and modem i have no other pci cards
    4.with old xp2000 was also stuck @ 148fsb
    5.i doubt it;s the mobo as i have the latest bios and i've seen plenty of ppl hit fsb of 150+ with the same mobo
    6 it;'s not the ram as i have very good o/c crucial ram AND i have tried lowering memory settings
    7. if i set my fsb any higher i get software errors in prime95 and sisoft sandra burn in mode freezes...not the whole system
    8. i get random crashes in 3dmark after extended time of looping...usually after at least an hr or 2

    this has led me to beleive that it's most likely my PSU running out of juice...or the only other possibilty is that my 2 sticks of crucial pc2100 can;t even handle 149fsb with low memory settings...this seems quite unlikely..any comments? i am considering an antec trupower dual vent 430W

    Yes you may find that the PSU is limiting you as I've seen it happen before. I don't know personally about the Antec Trupower PSU's though Topower PSU's are very good and have high combined wattage on the 3.3 & 5 volt rails. :smokin:

    Antec has been making some of the best power supplies for some time now. I have been using their PSUs for quite a few years and have never had a power related problem yet... nor have I had any shortage of power either. I use the 430w TruPower and it works quite well. :)

    Sorry, but I don't have the full spec sheet from Antec anymore. They had sent me one when I was reviewing the PLUS1080 case.

    GOOD NEWS!!!!1
    yesterday i got my antec 380Watt PSU and guess what?
    my cpu isn'y stuck at 148 fsb anymore...150 rock stable so far....it just shows that even a psu can be a limiting factor in o/c...while i don;t really expect much more out of my cpu mainly bcos of my internal modem probably won;t like fsb much above 150, it' still a nice surprise to find a bit more juics left in my system:afro:

    lol i wonder if any wants to be a generic 300W psu:cheers:

    NIC cards and non-SoundBlaster sound cards are usually a good place to start looking when it comes to troubleshooting high FSB problems. It could be the modem to, though I haven't used one in so long that these components were never an issue with my systems. I can't speak from personal experience on this one.

    nah i don;t have a nic...only an internal modem....wow i thought soundcards are always the last to trip up high fsb's....so it could actually be my fortissomo 2?damn taht complicates Kthings...although of course the easy solution would be an Epox 8K3A...which like other kt333 borads has 166fsb divider....hmmmm..nah i think i'll hold off till thouroubred matures a bit and then do a big cpu/ram/mobo upgrade
    thx for your help:cheers:
