    Default 2500k oc question

    Hello all,

    I have recently upgraded my system to a sandy bridge 2500k based system, and the problem with the motherboard recall notwithstanding, it's been wonderful and stable.

    The problem I'm having is that I have a gigabyte-p67-UD3 motherboard running windows 7 64bit ultimate edition. I was able to overclock the cpu to 4.5ghz on air cooling (and according to both speedfan and real temp, my system/cpu temperature never went above 45 celsius, even when I'm 5 boxing) Most of the time when I'm just browing the web or watching a video or something, it stays at around 35 celsius give or take a few degrees.

    My system has been running for about 2 weeks now. It's never crashed. Never blue screened. Never even had so much as an error message outside of an incompatible driver message that pops up when I reboot. But here's the problem. After I leave the system on for a few hours. It would lose it's Overclocked multiplier setting. It would go from x45 to x34 (the stock default) and I would be back to running at 3.4 ghz.

    No error messages are shown. At first I thought it was the cpu cutting off of turbo mode or something. So I would try to load up my 5 wow accounts, and play for a bit. Everything is the same really, frame rate, cpu/system temperature, nothing drastically noticeable, but I would run RealTemp or Cpu-Z and it would still show that I'm running at 3.4 ghz (x34 multiplier)

    If I reboot my computer, then it's back to 4.5 ghz again at x45 multi. But after a few hours it would drop back down to x34 multi. It's not a big deal performance wise but it's just driving me nuts as to why it's doing this? Anyone with experience OC'ing the new sandy bridges have any thoughts?

    As always, thanks to any gurus that may be able to help.

    Ya your going into Power Saveing mode there a way to trun it off had to do it on my gigabyte board as it used to do it. Not at home atm but its a setting in bios.


    and its a bitch to get out the powersaveing mode well it will be for you to get over 90% cpu use

    Thank you ebony!

    I couldnt find the setting you referred to in the UD3's bios setting, as there was nothing about power saving mode in the bios, but I did change my power profile under win 7, and set the "processor power management" minimum from 5% to 100%.

    Now I just need to leave the computer on for a few hours and see if I can keep my overclock'ed setting. Thank you for the tip once again ebony!
