That puts a slightly different spin on things. Information is still scarce on the new information from CPU-Z but coupled with Acer's
specs of the M5100, then it would seem the motherboard can safely accommodate an AM2 CPU.
The confusing part comes to the Phenom series, because those are AM2+. On one thread it was suggested the motherboard wouldn't be able to run the Phenom at its theoretical maximum capability partly due to the BIOS.
This provides an overview, which I assume is accurate, about the supported CPUs on the original motherboard model we started with. I suspect that Acer's F690GVM is essentially identical to the Foxconn (
supporting evidence).
One thread I did stumble across suggested the Phenoms would be limited in their clockspeed (either 2.2 or 2.6GHz from memory) due to the BIOS. And the motherboard seems to be confirmed as an AM2 rather than AM2+, so may lack the additional support for AM2+ CPUs.
With the
Wiki I would guess a Phenom X4 9650 would still be safe (but somewhat pointless) due to the same TDP limit as the Phenom X4 9500. Beyond that... most of the Phenoms don't exceed the TDP of 125 of some of the Athlon 64 X2s. But given the slight unknown socket and the BIOS, it would be a risk.
This is all speculation based on the limited information I could gather.
