Hello,

we are looking into implementing a Bitcoin payment system and are wondering about a few things.

Is there anyway to make sure that a transaction, with which someone will pay us a certain amount, will really be successfully validated and processed before it's actually inside a certain block?
Since the txs can hang in the mempool for quite some time, it's not really an option to wait till it's included in a block for real.

Best regards,
Mark

Another question,

when searching for a good config, what's the better option, get a good miner config wtih highest possible hashrate and then fine tune with core/mem clock or the other way around?

Hello,

I'm having some troubles finding a solid configuration for my setup:
E6850 @ 3.0 GHz
4GB RAM
Win 10 x64
Beta mining drivers
2x Gigabyte RX580 8gb

currently using Claymore miner with -h 1850, and the cards 1130 core and 2220 mem clock, but can achieve only some 630H/s.
I also tried the amdStak miner, but got similar results.

Any ideas what could be done or where could be the bottlenect, to get to some 700k/H withoud bios mod.

best regards,
MtD
