[ANN][ROI] ROI Coin | CPU Only Solo Mining | 15% POS | 18.07% Term Deposit

[CryptoMarv]

Did someone calculated when the hard fork will happen, I got between saturday night, sunday morning.

Yes you are very close on your estimate

At the moment ~2400 blocks until 25000. We get round about 600 blocks each day, so the fork will be in ~4 day from now on. Depending on your timezone it will be between sunday evening and monday morning I think. So don't forget to term deposit your coins before the fork, with very high interest rates.  Last chance...

I have recently observed that there has been an accumulation of addresses like 45bd-----------------------  in the pool, whom  doesn´t match the look of casual ROI adresses – often with much hashpower.
These ones may contribute for the network, but the coins will never be received. Maybe a Pool Administrator should check who´s connecting with previously mentioned adresses and should disconnect this one.

I think there is simply unnecessary energy consumed.

Thank you very much to the dev who really invest a lot in this coin!!!!

Sorry for the bad English

i noticed several ppl doing that, this one is an etherium address. probably misconfigured miner.

[ghobson]

That error is from when I tried to compile it from Mac OSX 10.11 and 10.12 directly. For cross-compiling, I am trying from Ubuntu 16.04, but I know for sure that the OSX CURL libraries are configured incorrectly and will work on cross-compiling the next few days.

Also, on my Ubuntu Machine I find that with optiminer's hodlminer the hash rate is much lower than what I get from the wallet directly through optimineaes enabled. Normally I get 80 H/s, but with optiminer I get 55 H/s on one thread and 40 H/s and 30 H/s on two threads. Does anyone have any tips for improving optiminer's hash rate? Also, is it better to run the miner on multiple threads if the sum hash rate is higher than the single thread hash rate (say 30 and 40 H/s on two threads vs 55 H/s on one thread)?

Also yes, I know 80 h/s is low but it's just a casual laptop that I mine on in the night when my house is cold enough to cool the laptop (partially) and the global hashrate dips. I've actually found a block in on this machine in just two nights!

Too fully take advantage of optiminer's improvements you need a modern cpu that supports aes and avx2. For me on a E3-1240 i managed to double the hashrate with it. ( using 4 cores , on ubuntu 14.04 )
In your case using 2 cores yields more hash, the higher the combined hashrate the better. ( i assume you have an old  dual core cpu )

What hashrate do you get with your E3-1240 on linux and how do you make a benchmark? I use the same CPU with Win10 and when the miner is running it shows between 400H/s-500H/s in each "accepted" line. No feeling if this is good or bad rate for my CPU.

I think the pool admin has no interest on disconnecting wrong addresses because he will receive all coins for himself which cannot be send to the real owner. Or am I wrong?

I get about 240 H/s with -t6 on the E3-1240L.

What cpu (exact modelnr.) are you on ?
Were you running linux native or as a VM on top of windows10
If it was as a VM using what virtualization technology ?
if you ran it as a VM did /proc/cpuinfo show the aes , avx and avx2 flags ?

I don't use linux. Only Win10 is running on my machine. Windows system information says: "Xeon E3-1240 v5 3,5Ghz". The miner is startet with 8 threads.

So yes E3-1240 v5 at 3.5GHz will be faster than E3-1240L v3 at 1.8GHz  ( totally different generation hardware )

I have a ryzen 1700 dont know how much roi coin I can mine per day. anyone can calculator it ? thank you guys so much

Why don't you try pool mining for one day and then you will see the result.

Your CPU has 8 cores, so I think it must be much more faster then my Xeon with 4 cores because you can activate more threads. At the moment I get ~400 coins a day, but this depends on the network hashrate. If you start mining and check your hashrate you can compare with my hashrate and calculate the coins you will get.

I think coins sent to the wrong adress are burned and could not be retrieved back ..?

You can do a quick experiment... just open your ROI Coin wallet and click send and now type in a wrong address... you will see the box turn red and that address won't be accepted. If there is a way to send coins to a wrong ROI address I am not aware of how to do it. The system "checks" that sending address and can refuse it if that makes sense. In the case of a pool I suppose if you mine pools with an invalid address those coins would in fact get mined but I don't believe the pool could then be able to deliver them. In other words this would likely be free coins for that pool Maybe a pool operator will chime in here with a more clear explanation...

Your welcome, you helped me realize i should have added latest wallet version number, to the top left corner of the block explorer

cheers.

How mining ?

[DisasterFaster]

How mining ?

• Solo mine from wallet with just a mouse click
• Solo mine with 3rd party miner a bit more complex for sure
• Cluster mine at http://roicluster.miner-pools.com/
• Pool mine at http://coinspool.cu.cc/info_roicoin

I also checked the mining address in block explorer and it cannot be found. So pool admin is not able to send coins to this address and will laugh about the stupid people when he gets many thousands extra coins.
