    Okay, so I've got my new 1055t running at 3.85 GHz (275x14) and bumped up vcore to 1.45, turbo off, cpu pll at 2.5, cpu/nb to 1.3, nb to 1.4, nb/pcie/pll at 2.5, dropped the fsb:dram to 3:8 (1440 i think, will double check in bios later), htt link and cpu nb link at 7 , and ram at 1.65. Temps are ok. I wanna push all the way to 4GHz (or as far as i can, 24/7 stable). Any ideas?

    okay its up to 3.99GHz (285x14) still at 1.45vcore, cpu/nb to 1.4, nb to 1.44. Trying to go further. what is the highest "safe" temp and vcore for thubans?

    Edit: 3.99 unstable, will try other multipliers

    I'm at 3.9GHz now (300x13), Dropped VCore to 1.375, CPU/NB to 1.35, NB to 1.42, and other settings the same. Ram is running at rated 1600, NB and HTT link at 2100 (ran at 2400). Temps are still good. But what are safe temps and vcore for thubans anyway?

    Ok thanks. Looks like I'm NOT upping VCore any higher until I get a better cooler then.

    Your wasting your core speed with that cpu-nb speed especially if your ram is 1600 at cas 7 or lower. 2500-2600 cpu-nb will max out 1333 cas 7 ram. Your bottleneck is your L3. Even then my 955BE only needed 3600 on the cores to have no other benefit. Also unless things have changed keep the HT Link and cpu-nb 1:1 for best performance.

    At 1600 cas 7 I'd have to assume but I'm thinking 3000 will be preferred.

    Use Everest memory bench to see the bottleneck on the L3 and use MaxxMem multi for tracking memory performance when multithreaded.

    also i've heard and noticed on my 1055t that temps are reported about 10c lower than actual. mine idles at 18c in a 20-23c room. not possible.

    Either way, I now need better cooling (at 1.45 VCore, heatsink gets HOT at prime95 load). Corsair H50 sounds good. Think it'll be enough?

    i have the h50 cooling a 1055t in my htpc - i have fans in push/pull and o/c'd to 3.6 @ 1.35v and it never hits over 35c (so prob really 45c)

    personally if you have a mid tower or full tower a top of the line hsf would be better than h50 according to reviews. i'm happy with my h50 but i only got it because the footprint is small even with two fans and it was on sale at frys for $20 off

    The best way to read the 1055t temps is go and grab HWMonitor.

    coretemp and hwmonitor say the same thing regarding temps (though the new hwmonitor finally says processor power usage)

    Quick Update: 3.72GHz (310x12) 1.3vcore, 1.35v NB , 2790 HTT link, 2790NB. Any ideas to push this procy further without more vcore?

    How much extra volts do you need for 3100 cpu-nb?

    Also nice core speed for such little volts needed.

    1.3vcore and 1.35 NB doesn't always boot for 3k+ NB but when it does it's stable.

    1.5v max for 24.7 usage on both vcore and NB with a max temp of 60C, so you don't get degradation. Hope that helps. Also the settings in you OP sounds like it's best settings to run at for 24.7 usage with board temps and cpu temps in mind.

    I was always wondering if it's better to have a higher fsb (or HTT in this case) than more GHz. I could probably squeeze out more than 311 but I'd have to bump down ram divider. Also, 1.45vcore is a bit too warm for me until I get a better cooler. It maxes out on around 55+ on prime when I use 1.45. Also, is more HT link and Nb frequency better?

    HT Link, doesn't matter as much. NB frequency, yes in terms of benching but not as much in 24.7 usage.

    So my current settings are 24/7 good, or should I push more fsb (htt)? And, is it a good idea to use CnQ while OC'ing?

    CnQ yes, once you have dialed in your 24.7. My opinion on it, anything at 3.7Ghz and above on ANY modern cpu is plenty(close to overkill but everyone loves the extra oomph), while leaving IMC/Board clocks untouched.

    hello i have the gigabyte GA-MA785GMT-UD2H motherboard and an amd x6 1055t processor with 2x2gb 1600 mhz sticks. i was wondering how i can go about overclocking my computer.
    thank you

    To start, what are your bios settings, and fill out your system specs in the control panel.

    What's your cooling and PSU?

    Here's what I did for mine (Your settings may be different though)

    CPU Clock Ratio: x12
    NB Frequency: x9
    CPU Host Clock Control: Manual
    CPU Frequency: 311
    HT Link Width: 16bit
    HT Link Frequency: x9
    Memory Clock: x5.33

    Voltages:
    System Voltage Control: Manual
    VCore: +.025
    DDR3 Voltage Control: 1.65
    CPU PLL: 2.58
    CPU/NB: 1.35
    NB: 1.44

    And don't forget to leave PCIE Clock on 100.

    Depending on your board, cooler and psu, you should be able to hit high fsb (htt).

    My cooler is the arctic cooling freezer 7 pro rev.2 and the psu is Biostar 650 W 20+4 pin
