Core i5 750: Your Overclock?

So the question I want to post today is towards those with Corei5 CPUs.

What Overclock were you able to achieve?

What settings did you use:

CPU Ratio Setting - ?
BCLK Frequency - ?
PCIE Frequency - ?
DRAM Frequency - ?
QPI Frequency - ?

DRAM Timing Control
CPU Clock Skew - ?

CPU Voltage Mode - Manual
Fixed Voltage - ?
IMC Voltage - ?
CPU PLL Voltage - ?
PCH Voltage - ?
DRAM Voltage - ?

Load-Line Calibration - ?

And What Cooler did you use?

I have 3 threads going. One over at HardOCP, another over at Xtreme Systems and this one. The idea is to get the most data possible in order to gain knowledge about the Core i5s general overclocking abilities.

  1. Bumping this because I'm interested in the results.
    I myself do not own a I series processor so I'm of no use.
  2. Gah, damn you elmo! I just ordered my Xigmatek LGA 1156 bracket yesterday and my RAM still hasn't arrived. Gah, I'm hoping to be in the 3.6-4.0 GHz area, anything over that is just bragging rights and I don't give a damn about that.

    Maybe in a couple of weeks I'll be able to add in my results, can't wait! (yes boys and girls real overclocks can take a week or more.)
  3. As and aside can someone post up the results every once and awhile because I don't want to hit "See results" so that I can vote later.
  4. Common guys and gals. If you've got an i5 oc'd.. please share your results. This data will be used in conjunction with two other polls on other sites to give us all an idea about the potential of the Corei5 750 chip.

    A lot of peoples like to OC at stock voltage as me and it's probably why you don't get any answer for "What overclocks were you able to achieve with a Corei5 750?".

    You might get answer more easily if you change the question to "What OC you can achieve with stock voltage?" or "What are your OC and voltage?"

    BTW, I haven't seen an owner who can't achieve at least 3.6GHz on i5-750.
  6. Bump, with cute pictures!







  7. Hello,

    I got my P55A-UD4P at 3.6ghz I had it at 4.2ghz but the temps got to where I didn't like it. Right now, my core temps are in the lower to mid 30c for idle and in the lower 50c under load.
    I set my bclk to 180 and had to set the ram multiplier down to 8 which left my rams at 1440. PCIE at 100 and the Multiplier at 20x. My dram was set at 9-9-9-24 but jumped to 10-10-10-26 due to the multiplier. My dram voltages is at 1.64v and my core v is at 1.120v.
    Hope this helps

  8. Someone voted "2.8-3GHz". I suspect it might not be the chip that is the bad overclocker in that situation. :P
  9. I'll have to come back to this later to post any of my specs. :) But I'm @ 4Ghz 1.32V generally speaking.
  10. CPU Clock Ration: x20
    QPI Clock Ratio: x32
    BCLK: 205
    Extreme Memory Profile: Disabled
    SPD: 6
    PCIe: Auto
    CIA2: Disabled
    CPU Clock Drive: 800 mV (discovered it was 700 mV, but in the manual it said 800 mV was standard which had given me some OC issues)
    PCIe Clock Drive: 900 mV (same problem as above)
    CPU Clock Skew: 0

    Spänning:
    Load-Line Calibration: Standard
    CPU Vcore: 1.43125 V (CPU-Z shows 1.408V @ idle & 1.392V @ 100% load)
    QPI/Vtt: 1.180V
    PCH Core: 1.080V
    CPU PLL: 1.900
    DRAM: 1.640

    Not necessarily, some chips are duds like my GTX 275 that can't OC as far as the others I've seen.
