If that works, we know that your FID is 32.AmdMsrTweaker is a command line tool for Windows which allows to reprogram the P-States used by various CPUs and APUs of AMD for their Cool&Quiet power saving technology. edit2: Forget it - please try a multi of 14.23 = 32 / 2.25 for P0.

Please try a 18.3 multi now, maybe after lowering the HT ref clock below 100 MHz, just to check if the AMD docs are correct and your FID is really 32 (I'd have thought it was 16 for a 1.6 GHz Bobcat).

Please download it, the multis should be fixed now for Bobcat, and some minor bugs have been fixed too. The next higher multi would be 32 / 1.75 = 18.3 => atm 9.15 for AmdMsrTweaker. Your default divisors are 2 for P0, 2.5 for P1 and 4 for P2. The reason for these odd multipliers is that the FID is fixed (seemingly 16 + 16 = 32 in your case) and that only the divisors are customizable (1 to 16 in 0.25 steps, 16 to 26.5 in 0.5 steps). Can you try to use a somewhat higher multi than 8 (actually 16) for P0 and check if that works, e.g., 9.15? That should result in ~1.83 GHz when using a HT of 100 MHz. So it seems like you could use a max multi of 32 (displayed as 16 by the app atm). So the default HT clock is 100 MHz for Bobcat, not 200 MHz? Then all multipliers are wrongly halved. Hey perfect, thanks for testing with Bobcat. Sounds like I got myself something to fiddle with this weekend To me, two separate files for on and off sounds like the easiest route. Should be possible with some batch file fiddling together with AmdMsrTweaker, and just run that manually? But either way AmdMsrTweaker might work out smoother than all the clicks and popups AOD requires to get the same job done.
#AMD K10 UNDERVOLTING SOFTWARE UPDATE#
Need bios update to sort it out, but doubt an update will arrive anytime soon. Atm I have to do this manually with AOD after each boot to stop the cores from downclocking under load. edit: sorry, I overlooked "flipping" - do you really want to flip back and forth?Yea, just want it to enable turbo, and then disable it again. An ugly console window will be shortly displayed when the app is run - I may change that later.
#AMD K10 UNDERVOLTING SOFTWARE DRIVER#
Since the app needs admin priviledges to load the WinRing0 driver (in order to write directly to the CPU registers), you cannot put it in the autostart folder though (unless you're still using WinXP) - you'll need to create a scheduled task for that. If the app works correctly, it should be able to do what you want - simply run "AmdMsrTweaker Turbo=0" on startup. Here are two screens (ever seen a Phenom running at 0.5 x 250 = 125 MHz? ) It's currently in alpha state, I've only tested it locally on my Phenom 9950, so please provide feedback and make sure to use a tool like AMD OverDrive to see what's actually happening. => modifies the NorthBridge P0 state (multi=8 (multis only supported by Bulldozer), VID=1.3V), its P1 state (VID=1.1V) and uses NB_P0 for all P-states = 3 => disables Application Power Management (TDP limiting) for Bulldozer (use 1 to enable it) => disables the turbo (use 1 to enable it) => switches to P2 (note: if C&Q is enabled, the cores are likely to switch very soon to another P-state, so this makes only sense if C&Q is disabled or if the high-performance power-profile is active) Quick guide: I'm too lazy to write a complete guide just now, so please take a look at the following examples:ĪmdMsrTweaker P2=8 modifies P0 (multi=12.5, VID=1.4V), P2 (multi=8) and P3 (VID=0.85V) Required: AMD CPU starting from K10 (Phenom/Phenom II, Llano, Bobcat, Bulldozer), Windows So it's only designed to tweak the P-states and supports newer CPUs. I dropped custom C&Q since default C&Q is supposed to work quite well for newer CPUs.

It's a console app, therefore no GUI and no Windows service anymore. I'm working on a simple successor to PhenomMsrTweaker.
