This is interesting:
im using OSX HighSierra in a MacPro 5,1 2010 built in 2011 "same as 2012".
1x CPU tray = x5690 = i7-990x = w3690 "Westmere"
its a 2nd Gen i7, x58 chipset, 1366 socket.
32GB 1333MHz ddr3 ECC Registered.
internal Wallet mining does: ~28kH/s.
power consumption is higher than 8th gen CPUs but still interesting.
Macs Fan Control 1.4.12
CPU A core from PCECI 74ºC
CPU A Heatsink 43ºC
CPU A Diode 60ºC
IOH Diode 50ºC
vs.Same Machine, Windows 8.1x64 "Bootcamp6.1"
CPU gets hotter, and Hashes are less:
~25.6KH/s Internal Wallet miner.
Macs Fan Control 1.4.12
CPU A core from PCECI 76ºC
CPU A Heatsink 46ºC
CPU A Diode 63ºC
IOH Diode 50ºC
Same Fan Settings. Same Ambient Temp.
vs.i3-8100 "the i3-8100 stepping B0 is the only CPU compatible with all Boards & all Bios for the z370."
and decided to test it...
temps at 100%, watercooled ~44°C
Fan Speed Silent. 800rpm~1300rpm.
Argon2d Speed: 26KH/s. External Miner.
cpuminer-avx2.exe -a argon2d-crds -t 4 --no-getwork --no-redirect -o stratum+tcp://crds.suprnova.cc:2771 -u -p
vs.Dual AMD Opteron 6386 "The Biggest & Fastest in the 6000 series." G34 socket makes:
80KH/s sse4.2 external miner.
64KH/s internal wallet miner.
@ 3.16GHz. with Supermicro snk-0050AP4 cooler "the biggest 4u cooler for G34 socket, also needs optional G34 adapter", with Dynatron A14 "3U", needs faster fan settings in the Bios.
Temps must be lower than 55°C or the CPU's will Throttle down to 2.8GHz or less.
Tyan s8232 Board. "Needs 6128 CPU if Board needs to update the Bios to detect 63xx CPU."
32-Cores "No HyperThreading" but the miner must have additional options...
Or won't detect properly the amount of Threads and Cores, CPU load will be less.
Those results are at 100% CPU load 32-cores, if Not, settings are wrong.
--cpu-affinity 0xFFFFFFFF -t32
Argon Miner must be forced to work with 32-Cores.
But I think leaving 1x out is better if also GPU mining,
Replace any F with E, and -t31

vs.i7-970 Windows8.1x64 Credits-1.3
2nd ge" i7, x58, lga 1366 socket,
Similar to w3670 = x5670 = x5675
vs. i7 1st gen, Transistor size is smaller 45ns vs. 32nm, has 6-cores vs. 4-cores, more Cache , and new AES instructions.
With external miner & pool = 26Kh/s. SSE42, AVX crashed. ">2.1KH/s per thread."
With internal Wallet miner = 23KH/s.
HyperTheading=On. 3.3GHz.
Watercooled with CoolerMaster Liquid Pro 120 has 58~60°C, depends on ambient.
NB 62°C
SB 56°C
vs.i7 7700K does < 32KH/s with HyperTreading Active, "external miner I guess can't remember, and sold the cpu"
HT turned off does ~23400 H/s.
in Windows8.1x64 latest build.
