I'm trying to fix a machine for a friend. I get a feeling it never actually worked right. It's a Shuttle XPC SA76G2, which from what I've gathered, supports CPUs up to 105W TDP and has a 250W power supply.
The Phenom X4 9950BE (Agena) is 125W TDP with 1.30V VID.
The BIOS does not have provisions to decrease vcore or multiplier, unfortunately.
I managed to get Windows installed, but any sort of stress testing will immediately cause the machine to reboot. Hooked up to my Killawatt, I see that it's drawing 300W, well over the 250W PSU rating.
As a proof of concept, I'm using PhenomMsrTweaker to reduce multiplier and VID, and am getting rock solid stability, with power draw not exceeding 200W at the wall. I will try to find the limits, since it's "only" at 1.15V VID and 10x200=2000 right now.
I have not built (or really even touched) an AMD machine since the 462 days and know nothing about these K10s. Since there is no bios adjustment, is there a way to pinmod these CPUs for lower vcore/multiplier?
Again, it's not my machine, and I'm imagining the owner is not wanting to spend any money (although how a 9950BE ended up in here, I have no idea)
Thanks.
If there's no easy solution, I'll have to have it run PhenomMsrTweaker on boot and advise to get a lower end (or Phenom II if supported) and sell this 9950BE
