Does anyone here know what AM3+ motherbird is required to run one of these Opteron 3000 series. I'm thinking of swapping out my 8350 FX on my windose box for an Opteron 3365 (65W/2.3GHz base) because the new forced windows update to 2020 H2 broke frequency control even further and leaves me in an awkward situation:
In the recent past (almost ~2 years ?), frequency control was broken in windose builds, leaving the user (me) only two choices. Either run at the lowest frequency, 1.4GHz, or run with no limits, which for me means running all or nearly all cores under full load at base/boost of 4/4.2GHz, which is terrible perf watt.
My cooler ends up spinning to very whiny frequencies since I constantly have 5 to 7 distributed computing threads running.
Before the forced windose update, I had work around to this windows bug, namely to use AMD Overdrive which allows one to set a desired voltage and frequency for the top frequency. This worked quite well until this last forced update, and now it simply crashes windose whenever trying to use a custom freq/voltage in Overdrive.
Now normal people could simply limit the frequency through the BIOS. My problem is that I have an OEM motherbird, with no such option.
What do you guys think are the odds that my OEM board will recognize a 3365 Opteron?
It seems that the 3380 is using half (possibly less) the wattage
at 2.6 GHz as the 8350 is at 4 GHz.
So perf/watt has declined to 77% by clocking to 4GHz, and that's not counting the memory/IO penalty that running at 4ghz vs 2.6 ghz entails. That might be another 10% hit, or slightly more. End result for running at 4GHz might be 65% the perf/watt of running at 2.6GHz.
