    Angry overclocking AMD Athlon64 3500+ vience

    Hey Every1, im havin problems getting my 3500+ stabely above 11 x 231, im not sure wat the problem can be bacause iv read on loads of forums that people have gotten theirs at 2800ghz! Any way my System:
    athlon64 3500+ vience @ 2541ghz, 1155fsb
    Asus a8n-sli
    2x512mb giel pc3200 ram
    Leadtech 6800GT 256mb
    q-Tech 650w psu (cheap sh*t)

    im thinking it may be because of my psu but i dont know, any help would be much appreciated, thanks.

    Lower your HT multiplier to 4x if under 250Mhz, if over that go down to 3x
    Also lower your CPU multiplier to gain a higher HTT/FSB, however watch that your RAM frequency does not got to high, use a RAM devider for higher HTT overclocking.

    You may also have to raise CPU voltage and/or RAM voltage, but be aware of the heat repocussions aswell, use good cooling and make sure you have suffcient air circulation.

    well today iv tried again at overclocking it and no matter what it wont go above 2600mhz (about) without either blue screening or just not booting, iv even tried my fsb bump at 2x! Could having a ****ty cheap power suply cause these problems?

    It maybe the PSU but have you increased core/mem voltages and what load temps are you getting (what sort of cooling are you using, stock)?

    at the moment im getting about 52 deg. max at 100% usage, im using a arctic cooling fan with a very large heatsink on it. iv tried increasing my cpu voltage and ram but still cant get it any more oc'ed.

    List all of your settings, CPU speed/HTT/HT/ram speed/ram timings/CPU voltage/ram voltage. With the info you are giving, there is no way to tell what your problem could be.

    lol, ok,

    cpu speed: 2541mhz
    htt: 231
    ht: x5
    ram speed: 231Mhz
    ram timings: 2.5/3/3/6
    cpu voltage: set to 1.55v, but cpu sez 1.504v
    ram voltage: 2.9v


    i know my Giel x2 512mb pc3200 DDR400 ram is quite oced at the moment but iv tried limiting it aswell to get a higher clock speed and it makes no difference.

    You need to set a divider on the ram to slow it down. Set it to boot up @ 166MHz in bios, that should give you some room. Also, set the HT to 4. If you plan on running the HTT over 250, set the HT to 3. I always leave my HT at 3 as it makes almost no difference in real world speed anyways and that way I can turn up the hTT as high as I want to in windows. That Vcore should get you to 2600MHz, but you may need to give it 1.6V to go higher. I would say set it to 1.6V and see how far it will go. I would be surprised if that combo could not do 2.7GHz.

    You could even try setting the ram @ 133MHz at startup to make absolute certain it is not the ram holding you back. I would have to say that is the issue. That and the HT set to 5 will cause you problems.

    You need to set the HT to 4 when you are overclocking. I cannot stress this point enough. And if you try to run the HTT over 250, you must set the HT to 3. There is absolutley NO advantage to setting the HT to 5. You are running the system bus much too fast with the HT @ 5. Set it to 4 and leave it there. I guarantee it is the ram stopping your overclock, not the PSU.
