No problem. i wish you the best in your search.

i have 4 of the 61xx ES chips.

i'm talking about Piledriver "ES" chips. Not standard Piledriver Opterons.

i've seen some overclockers using SuperMicro boards overclock via an additional board which taps into the bus that controls the voltage controllers. Specifically it was an Elmor Labs I2C board. Unfortunately i don't have time to look into it now. i think i saw it on Der8auer's videos...

They aren't easy to find. Rare as hens teeth.

i still run two of the Piledriver Opteron ES chips in my SuperMicro H8QGi-F. i also have 4 of the Opteron 61XX ES chips which i am not currently using.

here is the OCNG utils. hope it helps

Have you run memtest86 or memtest86+ on the ram? i would do this first to determine if you happen to have a bad stick(s). Is all the ram the same brand and type? If you find that you have a bad stick then its going to be trial error to find which one. Not a fun experience, after i flashed...

i am not sure that voltage is limiting you too much. i found that the voltage requirements to increase the GHz really starts climbing after about 3.8 GHz. i run with this TPC script: cd C:\tpc TurionPowerControl -fo 2 TurionPowerControl -set node all core all pstate 0 freq 4400 vcore 1.3250...

How is the optimization going? i haven't been able to run the NB at more than about 205 with stability. i still have the issue where under stress testing the machine will just shut down, but at this point i am thinking that it is a matter of the motherboard simply not being able to supply...

It is not so bad with only 16 cores going full chat. About 480 watts for the entire system using the Kill-A-Watt. Idle is around 260 watts. This is with all pb1 (all core turbo) set to 3.9 GHz, and pb2 (single core turbo) set to 4.4 GHz (which is 4.0 GHz and 4.5 GHz after multiplying by the...

hi Folks, i've been running a quad socket SuperMicro H8QGi-F motherboard with Opteron 61xx ES chips since 2015 as my home PC. 48 K10 cores overclocked to 3.0 GHz. The thing has been a tank, and solid as a rock (and it should be since the internals plus the SC748 case weigh about 80 lbs). The...

[EDIT] i found out after a bunch of further stability testing, that the lowered speed HT setting just kept the stability from manifesting itself (ie it hid the instability for longer during my Prime95 runs). The problem actually was the Node Interleaving setting in the BIOS. For some reason...

Update: With the processors still set at "Compute Unit" downcore mode i spent some time focusing on the voltage curve and pstate 1 (pb1) since that is where the CPUs spend most of their time. 3.9 GHz required 1.2125 volts 4.01 GHz required 1.2375 volts i stopped at 4.0 GHz since i don't want to...

i thought i would post some preliminary results. Using OCNG the processors seem to have hit a limit at current settings at ref clock 213. Beyond that is not stable at current settings (and i don't want to up voltage to CPU-NB due to increasing heat). RMMT really stresses out the CPUs more in...
