Did you pull the cards out and make sure all the heatsinks were tight? In Blades, low efficiency is usually due to chips overheating from poor heatsink contact, and these Cubes are notorious for loose screws upon delivery.
Right I unscrewed the device, pulled all the cards out, screwed a few of the loose heatsink screws in tighter and put the unit back together.
Now I can get the cube to hash at 31693MHS with an efficiency of 96.58% in low clock speed, if I switch the clock to high both the hash rate and efficiency start dropping, I also noticed one X today which wasn't there yesterday after I put the device back together:
ASIC_01-16: O O O O O O O O O O O O O O O O
ASIC_17-32: O O O O O O O O O O O O O O O O
ASIC_33-48: O O O O O O O O O O O O O O O O
ASIC_49-64: O O O O O O x O O O O O O O O O
ASIC_65-80: O O O O O O O O O O O O O O O O
ASIC_81-96: O O O O O O O O O O O O O O O O
Can anyone shed any light on why my hash rate and efficiency might be dropping when I try to run the device in an overclocked state?
I've opened this cube up again twice and removed and re seated the modules and am now back to square one. Thought I was making progress and now I'm right back to where I started
ASIC_01-16: O O O O O O O O O O O O O O O O
ASIC_17-32: O O O O O O O O O O O O O O O O
ASIC_33-48: O O O O O O O O O O O O O O O O
ASIC_49-64: x x x x x x x x O O O O O O O O
ASIC_65-80: O O O O O O O O O O O O O O O O
ASIC_81-96: O O O O O O O O O O O O O O O O
MHS:29513 Efficieny:098.55% on the Low clock setting
The screws on the heatsinks are as tight as can be, could I possibly have a duff cube?? Would re-arranging the modules make a difference??
I don't know how tight "tight as can be" is, but I'm wondering if you may have damaged the board/chips by overtightening the screws? You went from 0 bad chips to 1 bad chip to 8 bad chips.
Initially when I received the cube, without any fiddling I had 8 x's, see my previous posts, then after the first time I opened it and tightened the screws I went down to 1 x, now I've opened it a further few times, not over tightened the screws but just made sure they weren't loose and I re-arranged the blades and am now back to 8 x's, plus the x's are always in the same row, so the problem must be the board, I have spoken to the seller and he is awaiting word back from the supplier, hopefully gets sorted soon!
FINALLY today I received a new board via OC directly from yxt, now I've taken the old board out and put the new board in after switching over the mini blades and am trying to connect to it using 192.168.1.254:8000 but am unable to do so, I cannot even see the device anywhere in the wired devices section of my router!
Anyone got any advice on what I might be doing wrong here?? My routers subnet is 192.168.1.x
Do I have to flash this new board with some sort of firmware before I can use it to control the mini blades???
