    Hey guys, I've been tweaking on my processor with Throttlestop, and I'm running into an odd issue. I am able to get all my multipliers dialed up (currently running 26, 25, 24, 24; tdp 90, tdc 90). I adjusted the latter two up in an effort to try to eliminate throttling (tdp and tdc I mean). On longer benches, using prime95, my c0% cuts back to 50%ish when it shouldn't be. My max processor temps aren't getting above 80c, but it's still throttling back. Is this a power supply issue maybe? Or am I just totally overlooking something stupid? I had only one bsod so far, when I tried to push all 4 cores @ 26x across the board.

    Hmm, upon further use of Google-fu, it would appear that my processor is triggering TCC and toggling the TM1 throttling. I tried out the modified BIOS for A09, but the options to disable this TM1 throttling don't seem to do anything.

    Ok, now I feel like a dolt. Been reading for days and somehow missed that. Thank you sir!

    On a further note, now running 27,27,25,25 at tdp 85 and tdc 62, working awesome.
