Cpu

hey guys . need a little bit of help from people may already have done this.
i have

and im just using a i3.2120

just orderd 3570k and to be honist unsure it it would have made more sense to get a 2500k
im using crossfire 6850.so the onboard amd40000 doesnt mean anything to me. im going to be overclocking and i was thinking the ivy may get a bit hot.

  1. the ivy wont acheive as high of a clock speed, but they will still preform neck and neck when overclocked
  2. Hi

    Both the 3570K and 2500K are so similar in performance (stock and overclocked) that it really doesn't matter which you've chosen.

    Take a look at this review: http://www.bit-tech.net/hardware/cpus/2012/05/01/intel-core-i5-3570k-cpu-review/6

    I would say if you plan on a heavy overclock then you may be better off with the 2500K due to heat issue's with Ivy.

    So I guess it depends on your CPU cooler and how much you want to overclock.
  3. i heard ivy is meant to get better out of the ram.
  4. got an antec920 liquid cooler . the 2120wot im on now can be clocked its sitting at 3.3ghz dual core . even the 2500k at default 3.3 is huge diffrence . so if i get ivy running at aboot 4.2ghz i would be happy.

    I wouldn't say that's true, maybe when comparing ivy with SB-E, ivy may be slightly better when it comes to achieving super high RAM frequencies (2000Mhz + ) just because the IMC on SB-E CPU's sometimes can't handle massive RAM frequencies.

    But when comparing SB with ivy I don't think there's any difference when it comes to RAM.

    You should be fine, most 3570K's will reach 4.2Ghz with stock voltage or a very slight increase in voltage.
  7. You will do well with the 3570K.

    Make certain that you have updated the bios to support ivy bridge first.
    You should be able to just exchange the cpu's, and Windows 7 will take care of everything.

    At stock, the heat is not remarkable.
    Even with a mild OC to 4.0 or so, heat is not an issue.
    It is only when you are pushing high>4.5 OC's that may require upping the voltages that heat will be an issue.

    Do not worry about ram speed.

    The current Intel cpu's have an excellent integrated ram controller. It is able to keep the cpu fed with data from any speed ram.
    The difference in real application performance or FPS between the fastest and slowest ram is on the order of 1-3%.

    Synthetic benchmark differences will be impressive, but are largely irrelevant in the real world.

    Only if you are seeking record level overclocks should you consider faster ram or better latencies.
