Ouch, you're right. It looks like the archive is missing from that download location.

Try here:

at least until the original file host can resolve whatever issue is preventing access to the file via the normal link

another option is k15tk which is a gui frontend for amdmsrtweaker I believe

This is the same exact problem that I am having. I've followed the guide provided as well, have all the utilities to OC, but my APU (A10 7850K) still caps at 1700 MHz.

A88XM MSI Mobo

Honestly though, when reading through all the guide and the forums, I find it very confusing.

My MSI, did this even when I had all the power saving settings off. The only thing that helped was to upgrade the bios, and even then it would still lock itself to 3ghz even if I had a 4400mhz cpu OC due to the igp being used. This chip is extremely wonky, to the point you can only OC one or the other.

You have to edit your p4 and p5 power states to prevent the CPU throttling during iGPU usage, AND you have to have some or all of the power-saving features (particularly APM; possibly others) to get an actual performance benefit from the process.

If your board has underbuilt VRMs and/or socket and you're pushing it beyond its ability to deliver power to the CPU safely, the board may throttle you anyway. We saw that some time ago with a user that tried to watercool a 4.6/4.7 GHz 7850k on an ASrock Extreme6+ . He could get reported clockspeeds of up to 4.7 GHz, but performance stopped improving at 4.5 GHz, even when the iGPU was not in use.

I notice that the CPU doesn't throttle with some games, as Wolfenstein The New Order (The CPU even goes full Turbo!), and sometimes with Borderlands 1 and 2. With the most of the other games, the CPU lock at P5 state.

My P-States (I left Turbo enabled, with high clocks, so the CPU doesn't consume and heat a lot as if I left a +4.2GHz base clock).







The average power consuption is:
Idle: ~35W
CPU Only (Turbo Off): ~90W (with CPU at P3)
CPU Only (Turbo On): ~105W (with CPU at P0-P3)
CPU+GPU: 80W (with CPU at P5)
GPU Only: 55W (with CPU at P7)
Bioshock: 90W (with CPU at P5)
Wolfenstein: 125W!! (with CPU at P0-P3)
Borderlands: 95W (with CPU at P5 with some jumps to P0-P3)

PS: I put this modded BIOS (Stilts's GeAPM off), and now I have a similar behavior than Wolfenstein in other games.

TDP is around ~120W (127W peak) when gaming. I have custom heatsinks with a fan in my VRMs.

I and some others have tried to edit the p4 and p5 and it didn't improve gaming performances significantly. It is weird but true. See for example :

But you already answered to that thumb.gif :

I actually noticed that simply editing p4 and p5 states in amdmsrtweaker alone will not improve gaming performance. In fact, it can introduce stuttering and hitching which is annoying as hell.

I did notice improved performance after I disabled apm, though my 7700k likes to get crashy when I do that now. I'm not sure what is the problem, though for me, it is not worth it to perform a more-intensive diagnosis.

When playing games, the throttling isn't a constant as it is when running something like Furmark or GPUPi, so the performance loss is not too great, but you can still pick up a few FPS if you can manage to get it stable with apm disabled and p4/p5 states edited to match max clocks.

Really, you'd be better off running one of The Stilt's modded BIOS/UEFI versions that disabled GeAPM.
