    Overclocking Athlon64 4000 +

    Hi all,
    I have a athlon64 4000 +, and since I had my HD4850, I feel the need to overclock the CPU because I'm limited, I have the original fan. But there is a problem: I managed to overclock up to 2604mhz stable, 4 months since it rotates at 2604mhz and it is a full 65 ° idle and 45 (I know it heats but it is normal for a 0.13μ, and it was not long ways all. But as I go over the bar in 2604 mhz, that is no longer possible, then: between 2600 and 2700, although it boot but crash under windows when he arrived. beyond 2700 it no longer wants to boot.

    So let me know if I can go further, is that there's an option that I forgot to configure (I've heard of UDMA and PCI frequencies that must be blocked, but I did not find it in the bios)

    I said that I have a sufficient supply: 550watts brand, so it's not the food, the ram is good too.

    Thank you kindly help me with my overclock.

    If you do not block the PCI frequency you might have a problem, if these options do not try to Ctrl + F1 or put your BIOS update. You are right down the frequency of the RAM?

    I have tried a lot of settings, I managed to boot at 2695mhz, It arrive on the desktop normally, but after 5 seconds, the latter closes abruptly, so the system is unstable.

    I put the pci-ex frequency to 101mhz, the HTT x4, the fsb to 245, memory 166, the coeff to 11 and the voltage at 1.680volts (which is 2695mhz and 204mhz for the ram). The max that I have achieved in stable Test 2604mhz: fsb: 248, htt: 4x, memory: 166, coef: x10.5 and voltage: 1.675volts, since 4 months and it works very well but not like this to do more.

    Good evening, I finally found the best possible overclocking my configuration
    FSB: 24x
    HTT: x4
    Ram: Synchro Case @ 3 (instead of 2.5)
    VCore: 1690 to 1710 Volts (instead of 1,500)
    Vram: 2.75 (instead of 2.65)


    I tested in increments of 10MHz, I did not find a limit on the ram, it has remained synchro event with @ 3, the pc boot from (from top to bottom) from 2684 mhz, but superp 1M does not pass, Then I tested 2667 mhz: 1M superp password but not 2M. I then tested 2654mhz: superp 1M and 2M password but not 4M Finally I tested 2640mhz: 4M superp therefore I concluded that that is stable.

    Final setting:

    CPU: 2640mhz (instead of 2400)
    Ram: 240mhz cas3 (instead of 200 cases 2.5)

    And I won superp 1M in 1.3s compared to my old OC of 2604mhz ram 204mhz cas2.5. Incidentally I do 32.125s
