Hi there cataloging experiences with Cryptonote Miner and HD 7850 & 7870 rig. I had a hell of a time troubleshooting etc.
Firstly rig specs
Core i7 875k @ 4.3mhz cpu
GA-P55A-UD5 mobo
8GB dr3 1833mhz @ cl8 or 1600mhzcl7 ram
1SSD + 5xHDD
3x HD7850 2gb 1x7870 2gb,
Hashrate =1900h/s-2100h/s GPU only.
Miner used - 9.7
PSU 600w Bronze for cpu and hdd and cooling fans. + 12v 18a 180w PSU for 2 7850 (from my idle 3d printer
Windows 10
On stock settings.....cards quickly reach tdp limit. 69c will kill these cards, as apparent by the burning metal & epoxy smell. so really need to monitor temps.
Pros
Relatively easy and intuitive? Theres a large user base.
Issues,
sometimes command line options don't work. Sometimes, it's better to leave the rig in tune mode, as this stops freezing issues with displays.
DevFee causes big drop off from pools after the 1hr mark. I checked logs and the pool switching is the problem. If you turn off the display, the miner has a spaz and the pc freaks out causing low hash rate and expired shares. Logical differences and physical differences haven't been accounted for.. i.e reporting that the miner is going to use 2140mb of ram when physically, there is only 2048 addressable. Status displays only the first 2 miners, wheres stats for the others? GPU gives new name eveytime the system is rebooted, difficult when overclocking. Overclocking inside of the app caused bsods and crashing. Irrelevant feature. Remote management is good in theory, but should be turned off for security reasons. Also, disabling devfee did no appreciable decrease in hash, when active it produced 5 Dev Fee shares over 7 minutes....what's this shit? Screwing my shares expiring them and hashing your own pools? btw, as everyone said, don't try to connect to my pool and kick me out while you mine, of course the app will error out. Overclocking from catalyst, (Crimson is ruuuuubish) is now made more difficcult due to Claymores "Driver recomendations") If overclocking pump out the memory first, then when adding memory goes backwards, and some juice 1-2% when it evens out hash rate again, pump up the cooling, when its stable increase Core Processor clock, this allow more headroom to increase ram speeds some more. Also, when using older hardware(like my mobo) You need to add poweer to the units in ascending order (Furthest from cpu to closest) to smooth out ripple and prevent line level load drop (and also staggered hash counts)
Claymore 10.2 doesn't even run half descent. 323h/s as opposed to 440h/s? gummon maite (c'mon mate)
But, i am gratefull i can mine at full hash without your fee! i find it highly unreasonable how much you ask of people for your product...capitalism at it's worst...Anyone using these cards, nofee 1 is the way to go. otherwise mining wasted shares.
Also, low reported hash rates were due to windows system processes chewing up grunt for some wastey rubbish NSA spying...i mean windows updating *cough
