[XMR] Monero - A secure, private, untraceable cryptocurrency

[dalistar]

Rented servers are usually much too expensive to even break even. The cost of rental is usually many times the cost of electricity used to run the server. Of course that makes sense since the rental company has other expenses.

Anyway most CPUs will run something like 50-70 hash/thread where threads is cache/2. With that estimate you can work out some numbers.

what this mean ?

32.9 mHash /s

how i can use this Mhash ... this can useful for which kind of algo ?

The claymore thread quotes some of the AMD GPUs with pretty high hash rates:

About 810 h/s on stock 290X (Hynix memory).

That may be somewhat out of date

I didn't see that comparison but I saw the intel specs here which quote TDP of 91W. That isn't necessarily what it would use mining but it is pretty high as CPUs go.

Probably a benchmark using an old Bitcoin CPU miner. Useless except to compare CPUs with each other.

[aiwe]

Only 400 h/s from NVIDIA GEForce GTX 980 for now?   I hope someone will make improved CUDA mining software for Nvidia. So it is better to choose AMD for Monero mining because I got those 400 h/s on my R9 270X.

so it is not profitable anymore
this server price is 159 USD per month

It is not profitable to mine Monero on rented servers afaik.

It is occasionally profitable to mine some coin or another on rented servers, but you have to evaluate opportunities carefully.

what about
AMD Radeon (TM) R9 Series

this what hash i can get and how i can calculate by myself
and this they wrote hash 1004.972 mHash/s  this what kind of algo ?? is that sha256 or scrypt or x11 ??

[Rias]

Not sure about any of the numbers above, but 32.9 mHash/s (assuming the m stands for M) is higher than the total net hash (last I looked, 11 MH/s, might have moved now)...

Speaking of that, I always wondered whether CryptoNote coins hashrate is any accurate. Monero's one jumps up and down from 7 mHash/s to 15 mHash/s within 24 hours (based on ChainRadar).

Obviously, hashrate is calculated as difficulty / block_time. And difficulty here is the number of hashes roughly required to find the last block. Isn't it better to evaluate CN hashrates not with this simple formula, but rather include a series based calculation?

i missed something

if like this so XMR is not profitable any more ,,,, impossible to make rig for 3000 hash to mine 3 coin per day ,,, sure electric and internet and cost is more more high that this number

so it is non profitable coins

Difficulty is calculated over a window of 720 blocks, so that already takes into account some period of time (12 hours). In reality it seems that the hash rate really does fluctuate a lot, even if the estimate is necessarily imperfect. This probably has something to do with time-of-day as it always seems to have been synchronized to a 24 hour cycle even on coins with slightly different parameters. Maybe computers that are idle at night in some geographic area and being used to mine, lower off-peak power costs, etc. I don't think it is possible to really know for sure.

I know about 720-block window. And it should also cut outliers, in theory. Maybe 720 blocks is not enough?

It indeed looks like there's 24 hour cycle, but I don't believe that it's due to certain PCs being idle (well, unless botnets again?). It can't constitute 50% of the network? And how does one even assess mining profitability if it fluctuates by the factor of two on a daily basis?

Well when the block time changes to 2 minutes, it will then be 24 hours, since we didn't change the 720 block window. That will be back to the original parameters as designed by Cryptonote/Bytecoin. Perhaps the behavior will be different then. We also have some research ongoing for better ways to adjust difficulty.

On the contrary, I think, in some countries a lot of PC are starting to mine in working hours (you know, clever sysadmins install miners on office PCs etc.).

thats not necessarily true - the first rig I described here:
https://www.reddit.com/r/Monero/comments/3w2z9c/currently_whats_the_best_rig_to_mine_monero_and/cxts070

would use about , i dunno, 400 watts when all is said and done. This would cost $23 / month at 8 cents / kwh. (which is on the high end). This would get you 59.1 xmr / month, at current nethash. Which comes to 26$ / month. So, it technically is profitable, it just depends on the rig. Its definitely not profitable if you're going to rent hardware from some company.

I don't see any reason for the mining to be stopped at nights? Also, the pattern on ChainRadar suggessts that there's a drop around 8-10 am (UTC+0). If we are talking about the office nights, then the timezone of these offices should be somewhere in the West of the NA (or East of SA).

That's pure guessing of course.

In another coin thread there was a guy mining with 300+ free Amazon AWS, but it was free for him only 12 hours a day, so he was mining only half the day each day. This can't account for the 50% of the network I suppose (are there many with free access to huge amount of free Amazon AWS?). There is 24 hours period in many other coins mining too.
