Cryptonight sp-mod version 1 exe file has been sendt to the donators. My first afternoon of work gave an increase of around 10% on the 750ti.
This will increase in the next releases.

If you want to join the train please donate 0.2 BTC and recieve both the optimized Spreadminer (with source) and the Cryptonight mod.

Do you have an estimate on how much extra hash can you squeeze out of your cryptonight miner?

On a sidenote, your spreadminer v7 has the lowest fluctuation I've ever seen in any algo. It only fluctuates 1-3 kh/s.

I think 30-100% faster is possible but it will take alot of work. I have started with the easy pickings.

i have to agree ... the spreadminer is VERY stable and running like a charm at the moment ... would really like to see the optimizations in future ...

due to the windows cryptonight miner you distribute to the donors ( as you know i need linux source or app ) i decided to compile tsivs cryptonight miner sp ...

currently using 8x60 - it is running as below ...

which really isnt that bad ... i KNOW your miner will be more than that when you work on it further BUT i wont be able to use the windows one ...

compiled in fedora 19 x64 and running stable so far mining at pool.minexmr.com:7777 ...

what are your thoughts? ...

btw - as a side note - what are the best pools to mine that have cryptonight coins? ...

Pretty good. What do you get with launchconfig -l 8x30 ?

...i played a lot with launch configs long time ago and found out that -l 32x15 does perform nearly the same as -l 8x60. maybe it works with windows. -l 8x30 gives me less hash than default.

BTW. because of a kopiemtu source edit khash is displayed instead of hash. but thats obvious i think  

edit. POOLS i liked:
monero.crypto-pool.fr
xmr.poolto.be

its not too bad ... but could probably do better ... I have almost finished the fedora 20 x64 install which ill complete tomorrow ... that should enable the newer 6.5 cuda repo to be used ... im still compiling all these miners with the cuda 6.0 codebase installed from the fedor 19 x64 repo ...

im not I the office at the moment as its almost midnight here but 8x30 was processing at about 20h less per card ... ill confirm that when I get back tomorrow sp ...

tanx for the pool list ... I was at a bit of a loss with where to mine ...

those figures your cards are pumping out are quite nice ... oc? ... or stock clocks? ...

evga 750ti FTW... slightly more OC than factory.

in any case - nice hash for those cards ...

yes - additional 6pin.

Thanks for this, I will try it. What is the highest stable rate anyone of you have got with overclocking on the 750ti?

Last summer when I was mining cryptonight coins with a couple of windows 7 rigs I got stable hash rates in 270-290 area. Factory OC cards + some more clocks.

Just did some more windows testing 7 vs 8.1 and tsiv vs sp, found out two things. sp version gave a bit more stable hashrate and with windows 7 you can use -l 8x60, otherwise overall performance was the same. 8x30 stock gave me ~230 and OC ~255. 8x60 stock ~240 and OC ~270. Card was the lousiest 750ti I have.

-edit- This is one of the algos that like memory oc

[chrysophylax]

all good ... they are powered cards are they not? ...

yes - additional 6pin.

kool - i only have 12 of those ones ...

the rest are all the non-powered low profile ones ...

so i keep them at a reasonable temp and no oc - apart from their factory clocked oc that gigabyte have them as standard ...

ive set mine mining now for 24hours and i can only say this much ... the amount of coin that is minted in comparison to some others for the work involved is quite small ...

the algo is obviously not optimized to the most it can be - so time will tell ... but i think ill be pulling the miners off cryptonight for now until some improvements are made ...

does ANYONE know how to oc under linux? ... anyone at all? ...

The reason I haven't bothered much with CN coins is that the fudge factor was too high. I always earned way less coins than what the calculations would predict.

thats what i have found in only 24hours AND the coins are not validated yet ... 6.75 in 24hours ...

maybe im doing something wrong on my end? ... or im mining on the wrong site? ...

With a hashrate of 6.250 KHASH. (around 25 750ti's)

you get around 6.66 XMR per day with the current difficult and miner.

tanx sp ...

I did the calculations and I would be getting a little over 8 xmr a day ... which is a little over 0.01 btc at today's trade ...

in comparison to around .028 btc mining x11 at yaamp - that is a very large difference ...

but then again you have optimized the ccminer in git quite well too ...

With claymore miners, a high end desktop cpu can do about 300h/s or al little more whereas a R9 290X (hynix memory) can do 800 h/s.
The crypotnight algo is rather cpu friendly.

Probably due to botnet mining, the network hash is too much for gpu mining being profitable.
