There are no magic rules; you have to adjust your value to your pool and find the settings that will produces less rejects.

I use -dcri 20 for my 270x and 7950 rigs on suprnova and I'm getting less than 1% rejects.

OMG what update..I would name my unborn child to claymore but its illigal there... 

I was at suprnova for DCR for awhile too, but with having many wallets taking too much resources from my mac, i settled with zpool that gives me option of BTC payment instead of DCR.

Another issue at the pool.mn

Claymore, when the SOLO VERSION is ARRIVE ? Btw, it will be only ETH solo mode/DCR-pools or we can choose the both SOLO?

Man, give Claymore a break...  The poor guy has been working his ass off!!!  Give him a breather!!

First I want to say, great miner -- Nicely done Claymore.

Been reading about this for a few weeks and just fired it off on my rig last night so version 4.0 is the first version I have used.

4.0 mined all night then for whatever reason this morning, just stopped mining but GPU loads and Miner reported hash rate remained unchanged.

I noticed after 2 hours the pool indicated the effective hash rate was 0 but the miner was still reporting an unchanged hash rate to the pool.

I quit/relaunched the miner and didn't see a change within a few minutes, so I switched to a different miner (without rebooting) and it started up just fine.
----Note: I may not have waited long enough for the pool to update its reporting before I switched miners.

Don't know if this information helps you or the community but I figured I would share it.

v4 report

1. ran v4 B1, whole day and running well - quicker I feel vs previous versions.
2. I accidentally ran a HODL batch file and in dual miner's console, I witness a "GPU 0 hang" and "restarting miner - ok" error msgs, but continued on as per normal, however after a few minutes I could see that the dual miner has slowed down.
3. Since HODL is CPU mining, it doesn't impact GPU ETH or DCR mining _ I am assuming, the starting of miner message and eventual slow down maybe dual-miner related bug.
4. The other conclusion is the HODL process is just taking all the CPU juice and impacts the DOS box.
5. just for feedback to Claymore, pls look into it if the points above makes sense for your troubleshooting.

claymore, now that we dont have dag's any more... can you tell is there now a limit for minimum memory on graphics?

sorry for noobish q

The dag was generated in 3,5 secs on the r9 nano. No more cpu fuck and hardisk spinning. Good job Claymore!

whats the location of dags?

You still need at least 2GB graphics as the DAG is stored in the graphics as before. You might not need big system memory.

Claymore has ported the Dag creation code from the cpu to the gpu. So instead of making a file on the harddrive, the gpu generate the file in 3.5 seconds directly into the gpu ram. This is using less power, much quicker, and much bether for slow cpu rigs. (celerons)
