Vertcoin - 1 | ASIC - 0 | Lyra2RE | Decentralised | GPU Mineable | Open Source

[fraa]

Hello, guys
I have this kind of problem
My rig with 1x Radeon 7950 and 2x 5870 worked fine with previous algorithms of Vertcoin and other coins.

After the recent algorithm switch 7950 keeps working, giving ~3.4 Mh and ~12.5 of WU (intensity 19, worksizes 32 - 256 all work)
Both 5870 give just HW errors and around 1.7 Mh of false hashrate, doing nothing.
I tried changing the intensity, worksizes, clock and memory speeds - nothing helps. Also put the --no-extranonce flag.

Pool: give-me-coins, --diffuculty-multiplier is set to 2
ATI (AMD) Driver 13.12. Also tried above mentioned DLLs from 14.4 in the miner folder.
sgminer taken from official website

Did anybody get the 5870 running?

Don't forget to delete or rename the .bin files after .dlls are placed.

To answer your question:
first I am the author of all those versions. metallicjames was rather a pre-release, and after that I decided to change the difficulty to 256, as it was allowing miners to get more shares. so apparently the other followed more the pre-release version that the "standard version".
also at that time, I was using verter, and this was the parameter which was giving good aggreement between the hashrate reported by the miner and the pool...

I can always change that setting for lyra2re (but technically it should have been 256) 

OK, please post here once you'll release a new version with 128 diff for the original lyra (and possibly add the aforementioned aliases for lyra2 algos - similarly as badman74 did in his version for the original lyra2).

guys @ verterspool can you do something about the stratum disconnects ? they happen almost on schedule, every 15-20min or so

[jamesl22]

Is there an overview of the details on the exact changes done when going from Lyra2RE to Lyra2REv2? I know some hash algos got swapped out, there seems to be different params given to the Lyra2 KDF...

Lyra2 now uses 4 for nCols and nRows. We also fixed the implementation to include the basil and padding.

Hi, could you provide more information as to what you are experiencing? Also your rough location (US?Asia?Europe? etc) - and is it affecting all your miners.

Also any logs from your miner would be great.

Sorry for the trouble you are getting.

Sorry for the trouble you are getting.

Location: Eastern Europe, it affects both my miner rigs and its simply stratum disconnect, GF error, there is no error in the miner when this happends (beside stratum disconnect) its just like the pool went offline and back again instantly.

Hi,

Do you have a screenshot of the disconnect?

Hi,

Do you have a screenshot of the disconnect?

I enabled logging, here it is

Not related to sgminer specifically but I can tell there are a lot of places in the world where connections with little activity are not tolerated. Persistent connections are really first-world luxuries, with Romania/Bucharest apparently being an important exception.

how come other pools have no GF error at all ?

[felix18yu]

Are there any news regarding of Vertcoin?
percent makes it one of transactions decrease, which was not good for a Vert?


thanks:-)

4 rows of 4 columns would be 16 cells... I'm assuming the cell size ain't 64 bits, then. Are you coming to IRC?

ok released (with algo aliasing... untested...)

To all verters miners - there was a DB issue causing a problem for the last hour or so. This has now been corrected and the pool is operational again.

has anyone gotten this to work successfully with 15.7 drivers??

Yeah, replace this in the kernel directory: https://ottrbutt.com/tmp/bmw256.cl

removed two pragma unroll... hmmm... doesn't work for me.

15.7.1 @ win7 x64 works fine

15.7.1 @ win7 x64 works fine

with no hw errors?
