How come you set the thread-concurrency so high?It seems even 290x can go that far for other algos.
generally on other algo's the more you turn it up the more dedicated gpu ram will get used while hashing.. this is what happens on scypt and scypt-n
most guys have no clue what their doing with tweaking advice on cgminer etc.. they shout random value for no apparent reason lol
and maybe i don't know what i am doing either BUT i have a method to my madness
lol
my gpu has 3gb's of ram and i tweak cgminer / sgminer etc with a higher TC until i see the ram usage goes slightly over 3gb's and then cgminer will not run.
..then turn it back down a bit.. and either i use calculator to multiply shader count by a whole number or i do that adn add +1
..i head about plus from a guy here but don't know if that +1 is good though i thought it should always be an even multiple based scrypt cgminer docs.
and that is tuning for ONE gpu-thread.. what i just said will usually screw you bad if you go with two threads lol
So what happens is a lot of other misc algo's can be pushed a lot further so on Jackpot i maxed it on one one thread and then added a second thread
and since the hashing algo is so simple the miner can easily handle it no problem.. that config i posted for scrypt would not even try and load.. it would an error for sure lol
tweaking for two threads is another way of setting up the miner for one card.. both should ways (1 or 2 threads) give the same result if you know what your doing..
i could go on and on about this but you can find plenty of people to give you config settings tweaking advice.. i just do what i do
How did i know my ram usage ? i loaded up GPU-Z then loaded the miner and watched it as i kept starting and stopping my miner..
also read the doc's that come with cgminer
so to answer your question i used windows-calculator and i multiplied like 1792 my shader count (the gpu's technical hardware stream processor count)
so like 1792 x say a random number like 32 which gives me 57344 for thread concurrency and that is too high and the miner won't run..
so i just deducted by multiples of 1792 until the miner would start and run.. which is what i posted in my config
then after that monitor HW and WU and Hash rate and fine tune the Intensity for best performance and adjust scan time etc to match the pool / block speed etc..
that is the gist of it lol
if i was tweaking for two gpu-threads i'd prob do like half that TC normally.. 2 thread will never handle the full TC you can do with one gpu thread
i got away with it though in that config because this miner is running a super easy hashing algo ..which is usually not the case around here lol
edit:
that config i posted is doing about 81.5 MH/s on my one Radeon 7950 all night long solo mining pointed at my wallet.
