I have a HP Proliant DL830 G5 server in my kitchen with Windows 7 Pro 64bit running on it. Yes I know it is designed for OS "Windows Server 2008" but all drivers loaded ok other than IPMI (probably not supported by Windows 7 ) and I consider that a security risk anyhow.
It has....
8 RAM
Two Quad-Core Intel (R) Xeon (TM) Prossesors (2.5 Ghz/1333 MHz, 2x4MB L2)
Embedded Graphics card ATI ES1000, 32MB video standard
Three, HP AMD Radion HD 8350 1GB Graphics GPU cards fitted in pci-e riser
and one AMD Radeon HD 7870 Dual-X 2GB GPU in the process of being fitted externally (I have to mod the two power supplies with a pair of 6pin pci-e power feeder cables and a molex feeder cable with a voltage regulator to get 5V from the 12V for the x1 to x16 pci-e powered riser usb3 pcb).
It has 2 x 1000w PSUs
I am monitoring the systems power consumption with a watt meter to try tell what it is up to. The machine uses 294w at idle with monitor on.
When I run “ethminer -G” I get... “No GPU devices with sufficient memory was found. Can't GPU mine, Remove the “-G” argument” displayed. (power consumption = 294w)
When I run “ethminer” I get lines of hashing ~185,000H/s = 132,000hashes (power consumption = 347w) so I guess this is my 8 cores of CPU as the mouse becomes sluggish and windows explorer takes ages to open.
When I run “ethminer –opencl -device 1” I get lines of hashing ~53,000H/s = 28,000hashes (power consumption = 311w), I guess this is one of my HD 8350, 1GB Graphics GPU cards hashing?
Not sure? Anyone know what figures I should expect? I understand this command turns off my embedded GPU and instructs to mine on one pci-e card? Windows explorer works without haste. I tried to run “ethminer –opencl -device 3” but also got lines of hashing ~53,000H/s = 28,000hashes (power consumption = 311w).
I understand this command turns off my embedded GPU and instructs ethminer to mine on three GPU pci-e card?
Then I tried to run “ethminer –opencl -device 3 –mining-threads 3” and got ~123,000H/s = 71,000hashes. (power consumption = 348w). Is this the three HD 8350 GPUs running? Not much for 3Gig. Windows explorer works without haste.
Q) If it is the three GPU cards... they are less than my CPUs, No??? Can I run three GPU cards and 4 of my 8 cores as well, maybe in another instance of “ethminer”?
?Q) When I fit the AMD Radeon HD 7870 Dual-X 2GB... will the command “ethminer –opencl -device 4 –mining-threads 4” include the HD 7870 in the total hashing power?
Also am I right in thinking 123,000H/s = a miserable 0.123MH/s
I looked “ethminer --help” in I know I ask a lot but have gone as far as I can go on my own,
Thanks in advance, Paula.
