AMD 8-core CPU works OK but not throttling

Recommended Posts

AMD FX-8350 is not throttling, always runs at 4.1 GHz and high VCore. K10stat doesn't work on FX CPUs.

 

Also video crashes on boot 3-4 times but eventually works if I keep rebooting. I get corrupted video as soon as the desktop loads.  I have nVidia GTX 550 Ti with driver 331.82 (BlackWingCat nvw2k33182).

 

Any ideas?

I can use AmdMsrTweaker_1.1 to set the p-state manually:

AmdMsrTweaker v1.1.:. General---  AMD family 0x15, model 0x2 CPU, 8 cores  Default reference clock: 200 MHz  Available multipliers: 0.5 .. 31.5  Available voltage IDs: 0 .. 1.55 (0.0125 steps).:. Turbo---  enabled  unlocked.:. P-states---  7 of 8 enabled (P0 .. P6)  Turbo P-states: P0 P1  ---  P0: 21x at 1.425V      NorthBridge in NB_P0  P1: 20.5x at 1.3875V      NorthBridge in NB_P0  P2: 20x at 1.3125V      NorthBridge in NB_P0  P3: 17x at 1.2125V      NorthBridge in NB_P0  P4: 14x at 1.1125V      NorthBridge in NB_P0  P5: 10.5x at 1V      NorthBridge in NB_P0  P6: 7x at 0.875V      NorthBridge in NB_P0  ---  NB_P0: 11x at 1.1625V

... but ACPI power management is not working. CPU doesn't power up on demand nor does it throttle when idle.

 

 

 

 

 

BTW, I tried posting photos from my Dropbox, but forum rejects the "extension".

Make sure the link you use is a "direct link", one that includes the image extension .jpg or .png or whatever, and try again.

Cheers and Regards

Thank you, Dropbox image links end in ?raw=1   or  ?dl=0

 

For example:

OK, so no embedded image but click-the-link works:

FX-8350 runs faster than my stock i5-3570K, even though Win2K CPU driver is not optimized for FX Piledriver and doesn't understand multi-threading.

 

 

Also everything works on the Sabertooth, including USB 3.0 and ASMedia SATA. For Win2K this is as good as it gets!

When I clicked the above link, I could downloaded the image for my use, which is fine, but if you remove the "?raw=1" from the link, like this:

https://www.dropbox.com/s/x4j6198uzfptqf3/Win2K-FX-8350-Cinebench.bmp

then the image should display in your browser without having to download it. You can still download the image if you right click the link and "save link as" if you want. All just a user preference.

Cheers and Regards

AMD doesn't really recommend the FX CPU throttling in the first place as its known to reduce performance.

And one more thing - I'm planning to install Win2k on my AMD FX-based system as well on a spare drive. Can you tell me where to get the appropriate modified drivers from?

Sorry for the late reply.

 

Everything is a straight install, + BlackWingCat's  nVIDIA Display 270.61 for Windows 2000.

 

CPU throttling is the only problem. FX-8350 runs at full speed, though you can throttle manually with AmdMsrTweaker.
