@Claymore i can confirm that this error vanishes with miner version 9.5, everyting working stable, could you check somehow and fix it in future release?
@ffthomas take 9.5, this doesnt crash so often, only that it doesnt support suprnova login.

You are getting that because of your memory overclock/timing. Lower the clocks.

Just tried that, lowered by 50MHz seems to have fixed it. Same speed as well which is a bonus.

Dwarf works great now.

Dwarf was a big disappointment last 30 days mining XMR. Always connection errors, and payment 20-30% less every day. I really enjoyed it in 2014, now... something is wrong.
Left pool couple a days ago.

 they still havnt sorted out  polo payments with id  so cannot use them

I have tried at least 5 different XMR pools over the last week and I have to agree - (so far at least) Suprnova seem to be really great.

I had a problem with Claymore's new ssl connection causing Suprnova to ban my IP address. I emailed admin@suprnova.cc about it and got a reply withing 15 minutes. They had a bug on their side (and admitted it to me which is unusual and I find admirable) which they fixed and so I was back up on the ssl connection at Suprnova approximately 25 minutes after first realizing I had a problem.

They have lots of stats and information and they seem to be doing decent real-time quoting of connected worker's hash-rates. Many other pools have really slow stats or they seem to underquote your hash-rate. If anything Suprnova seem to think I have higher hash rate than I expected.

Anyway - my experience with Suprnova so far has been very positive and I recommend them.  

If you are one of the ones who really want to be able to mine to an exchange - dude.... just get a mymonero.com account, mine to it and take that extra 2 minutes a day to send from it to poloniex or wherever.

tbh i also want to mine to the exchange, is it free to transfer from mymonero.com account to polo ?

Just did a test transfer, 3.5 xmr with minimum privacy level (mixin 3) and the fee was 0.009 xmr.

edit: to sum up,

3.5 xmr from webwallet to kraken fee 0.009 xmr
3.5 xmr from kraken to local wallet fee 0.05 xmr
3.5 xmr from local wallet to kraken fee 0.004 xmr

 I assume it cannot be done
