You need to wait for a new block to be found. That's why bigger pools cut on variance as with their hash power new blocks are found way quicker.
Correct me if I'm wrong.

Hello superresistant ! Help me.

I work 3 PC - 1 CPU, R280x and R270 x. All computers come one and same error.
Errors on all computers are constantly in 10-20 minutes. I changed the ports, all else fails.
default settings, as in the example. What can be done. Thank you.

This screenshot from the PC to the CPU.

Claymore's CryptoNote GPU Miner v9.6 for R9 280 x and r9 270 x    Catalyst v15.12. -a 4

Claymore's CryptoNote Windows CPU Miner v3.5 for CPU

Good. Thank you. I'll try for the CPU miner. But I still have 2 video cards, and there are the same problems. I told her about the CPU, because this computer I have at home, and the video card in another room. I do not know the reason. Can I set up something wrong?

How blocks like this one will be handled? Divided out to the few lucky guys which send a share within this second?
Your pool often generate such 99%/100% blocks. I´m mining since weeks here with ~3300 H/s but I never had the
feeling that I also get a bigger peace of the block-cake if such a 1- or 2, 3, 4-second block appears.

Bonjour,
Almost 2 weeks mining 5 or 6 hours a day with :

ccminer.exe -l 8x64 -a cryptonight -o stratum+tcp://xmr.crypto-pool.fr:6666 -u 45kP7zdhzT3B3oWrSA78yhNRzTDjeGpHj1TJCTchweWMSM7yDszRmZjHG2Rr2iBsj3UPkgCkR2tERcd HSqhLjcxM34Dkj8o -p x

and balance is 0.0000000000000000000000000000000000000000000000000000000000000000000 zero

Is this command is correct ? Am I doing something wrong ?
Full node monero running on this machine (W10 86_64 i7) and mining for myself with 6 threads on the same time on another monero-wallet-cli address

Merci de vos lumières et de votre indulgence
Paris loves you

Hello conneXion,
If you are French, send me a PM in French to explain the situation please.

I cannot find your address on the pool, are you sure the address is correct ?
What mining-software are you using and where did you download it ?

Bonjour,

Thanks for reply,
It seems that my miner is rich $!##* !    : )

Same hashrate without -l 8x64

Same problem on port 3333.
Anyway I read somewhere that hashrate indication is false with GPU miner ...
Obviously it's true.

I get rid of the first address, as you can see on the command above, the address changed.
Is it possible for you please to check with this one :

42XzhFyTXBC4UPLWgbrmgwTiXKCHYuaDS56gdmhHgFm3Fwjh6PE9cPtUwXTtYtpzMWFDtqStYdZ9HNQ cxoCgwYLX4oDJEkW

Also, I use to mine for myself on 2 different machines (different location) with full monero node on this same address, plus with ccminer.exe, shouldn't I do it ?
Please tell me if I do anything wrong, and if you have some advices ...

Thanks

I have tested this pool with claymore miner and NH. and payouts are regularly.
I'm satisfied with good support of "superresistant".
Thank you and god bless you man.
