CryptoDredge 0.26.0 — NVIDIA GPU Miner

[igorsantos]

does anyone know the settings for mining nimiq on icemining.ca, I used this:
CryptoDredge -a argon2d-nim -o stratum + tcp: //nimiq.icemining.ca: 2053 -u NQ74 HBN1 61NV M68T 41Y2 95DX 2GQL RQRJ F0QC-Pc =nim
but it didn't work.

When mining zcoin with this miner it tends to mine zero hashes after a week of running. I always have to keep an eye on this. Is my overclocks to high. I set them around the same as the new equihash algo settings? Or is this miner generally not as stable as gminer when mining btg? Gminer I can run for a few weeks to months without issues

I have my 1060 using this miner and it only resets when I update software or power down the machine. Typical use is over 2 weeks and up to a month, so its pretty solid for me!

This version has also been same since right at beginning of October so thats been nearly 4 months.

try with no spaces in your account #

This works: \CryptoDredge -a argon2d-nim -u NQ26Y80D0P3G97K950E9DBURGH49E8X002BF -o stratum+tcp://nimiq.icemining.ca:2053

So is this miner dead, i.e. no longer updated? If not, can we do something about the duplicate shares in cnturtle (maybe other cn algos too)? CD keeps submitting duplicate shares for cnturtle causing pools to ban the miner

[ZombieWorm]

Have you tried him on the discord channel?

[cryptoyes]

You obviously didn't visit the discord channel before suggesting it to others ... it's a ghost town

I'll try to fix it
UPD: Could you check v0.23.0 for it?

[cryptodredge]

Soon as I mention it seems like an update is now available.

Testing 0.23 right now, and will let you know. Did you actually implement any fix in 0.23 for this duplicate shares bug or was 0.23 planned for release at this time? The dupe shares problem has been reported on your github for quite a long time.

[cryptoyes]

I can report the problem is still there. A duplicate share is sent after a devfee session - then pool bans the IP. I can't say for certain the problem is linked to the devfeee session, because this time the duplicate share was not the first share following the devfee session, but there were no duplicates before the devfee session - log below. I have another miner running 0.23 which had 45+ successful shares and no devfee session yet.

This pool is run by an OP I know who disabled IP banning for duplicates, but all other pools are banning the IP if a duplicate is sent (on suspicion of stealing hashrate) hence CD is still not reliable to use (at least on this algo).

A duplicate should never be sent by the miner during the same session so this must be a bug.

More reports: two duplicate shares, both shortly after the devfee sessions (but not immediately), but four devfee sessions in total - so it doesn't happen for all devfee sessions. This is still better than before:

Code:

$ grep -P 'session|Acc|Rej' /log|grep -P 'session' -A 10

And more reports. It is now clear that the problem is still there and it _only_ happens shortly after a devfee session, hence it strongly suggests that the problem is linked to the devfee, note the stream of dupes after some devfee sessions below ... 9 out of 700 shares is more than 1% loss of hashrate:

... it's getting worse, it feels as if some cache of dupe shares is growing with every devfee session or something. heres the latest devfee session and all accepted/rejected shares after it (1503/23 is now 1.5% wasted hashrate)

Here's the entire log of sessions and shares: https://pastebin.com/s97g6ps9

You can see which shares are duplicated by the diff value. For example, share 19 is a duplicate of share 11, and share 229 is a duplicate of share 224, and so on

I can't work out what exactly causes them, but they always pop-up after the devfee and they are all a duplicate of some older sahre (not the immediately previous one).

Could you investigate and fix this?

[cryptoyes]

and here's another "duplicate share" (the previous ones were "duplicate share2" ... note the "2", that's probably from the pool?) which got me banned: https://pastebin.com/cp3dPSiu

... again, happened shortly after a devfee session. Please look into this, it sounds like it should be an easy fix

       Also have this error on ver 23 mtp-tcr.

I've had a chance to run this over my rig and it'll work on all old and modern Nvidia cards except for the 1650 Super.  It only gives a GPU Critical Error message and restarts the miner.  Works fine on all other cards ranging from a 750 ti, 1050ti, 1660ti, 1070 and RTX 2080.  Just the 1650 Super fails. 

Since this GPU is still relatively new, has it not been coded for yet?  I am currently running the latest version 23.0
