We've discovered that the muliplier downclocks under load. Mine does. I've put in the settings given in the OC guide. What stops it is this. SajinFixed the multiplier dropping issue. What I did was... From the Overclocking tab in BIOS, navigate to CPU Configuration, then navigate to CPU Power Management Configuration and set: IA Core Current Max(1/8 AMP): 2040 Power Limit 1 Value(1/8 WATT): 2040 Power Limit 2 Value(1/8 WATT): 2040 Long Duration Power Limit: 255 Long Duration Maintained: 120 Short Duration Power Limit: 255 Holds a steady x47 now.  Is there a better solution or a bios fix?

yeah, it's quite interesting why those power settings make the multiplier stop fluctuating under load. it would be nice to hear an official explanation on this one and/or a promise of new BIOS free of this bug.

Yep, had that multiplier downclock issue as well... I think it has something to do with a CPU power limiter on the board. I guess those higher values posted by Sajin took the "limiter" off  Now my CPU doesn't downclock when loading LinX or Prime95

LMAO! I was just like that before I got this board. I had no social life for a week straight right as I received it  I treated it like my baby, taking out of the box etc. etc.

Just got my system together yesterday with a 3770K and saw it was downclocking. Changed in bios the following settings that are listed in jacobs OC guide: disabled Vdroop Enabled PLL voltage Override CPU Core Control set to 1.25 V C1E set to disable CPU C3,C6 and C7 also set to disable Also made changes listed by Delirious in this thread I am running BIOS 1.04 Here is what weird. This did stop the downclocking till I tried changing the RAM timing from 1333 to 1600 (which is what my ram is rated for). When it didnt like the 1600 I had to go back to 1333. Since then it has been downclocking again. Any suggestions?

Update. Swapped to Bios 2. Flashed to 1.04 and re-entered settings and down clocking has stopped. Have to figure out what happened in Bios 1.

well. i tried the OP settings but it wouldnt allow me to enter the same values. heres a screenie. my 3570k still downclocks to 1600mhz  i gues its not that big of a deal. it goes to 4.5ghz whenever i push the system. ie games, benches

Mine CPU downclock only in idle with C1E enable on 1600MHz. On load 3.492MHz without Turbo. With Turbo 3.692MHz. I disable C1E to avoid downclock.
