AMD Athlon II X3 450 Rana 3.2GHz

Hi I am a beginner so I do not know very much about overclocking or computers.

I am looking to build a cheap build and I was wondering if this was a good cpu to go with. Any better options for around the $75-100 range?

And if I do happen to go with this cpu how much can it be overclocked, and to my understanding I believe it can be unlocked to a quad core.

And which mobo would be the best at unlocking the this 4th core?

Thanks in advanced.

    jaylim0512;

    Are you looking for a gaming system? Or just a general purpose computer? Have you set a budget yet?

    Athlon II X3 450 @ $80 is a good choice, especially if you're able to get the 4th core unlocked and stable.
    The success rate at getting the 4th unlocked is pretty good, but never a guarantee. It's more the 'luck of the draw'
    getting a good CPU than the choice of motherboard.

    Unlocking and overclocking; if you do get a 4th core unlocked you might find it's unstable when you try overclocking.
    So you'd be left with a choice of overclocking with 3 cores, or staying near stock speeds with 4 cores.
    To get a good stable overclock on 4 cores you'd have to get lucky twice. Once to get the core unlocked, a 2nd time lucky
    for it to be stable overclocked.

    The X3-450 is not a Black Edition with an unlocked multiplier. So you'd need to increase the reference clock and CPU voltage to OC.

    And the amount you're able to overclock can vary. If you look at the X3 450 owners feed back you'll see a lot of comments like:
    "Was able to unlock and overclock. 3.7 on three cores and 3.4 on all four cores."

  2. +1 on WR2's post for a good starting budget gaming build except I would go with this mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813138179 has 4 slots for memory vs 2 on the A880G+ leaving room to toss in more in the future and its cheaper due to not having onboard graphics which you wouldn't need with a dedicated GPU.

    P.S. I haven't had any luck unlocking a Athlon II X3 with the A880G+ I don't know if its the BIOS that came with the disk or I'm just extremely unlucky but I've gone 0/4. Can't get windows 7 64 bit to even try to load when trying to boot with 4th core active.
  3. I did check the NewEgg customer comments to make sure people were having unlocking success with the A880G+.
    It was the usual some did/some did not result you'll see on any ACC board it seems.
    That A770E3 is a good choice, and less expensive too. Just update the BIOS before any unlock attempt.
  4. I don't know if I ever updated the BIOS on the A880G+, I had a nightmare of an issue on the mobo of my 1st build ever. After I updated the BIOS on an Asus it stopped reading my core temps(I had tweaked a few things along with that BIOS update not sure what effected my temp readings) After that I haven't messed with BIOS updates unless I had too lol. I might have to update the BIOS on the couple of A880G+ I have sitting at home and retry unlocking those X3's now tho :)
