\[solved\] Keep getting bluescreens \* mining is hard
-
Earlier I got 120Mh/s bitcoin mining with guiminer.
It was too hard so I found feathercoin I tried mining with guiminer scrypt and it starts mining at like 20 kh/s or something and than screen starting flickering black and everything drops to like 2 frames per second and than I get a blue screen.
xfx radeon 7750 core edition 2gb ddr3

check out -I or intensity parameter.
freezing screen or even bluescreen are an often seen behavior, if the intensity is too high for a card
If you are on windows set it to 8 or even lower and increase it step by step until the problem occurs again and use the last error free setting
-
That worked but I only get around 60-90 Kh/s

You have to remember that scrypt uses a lot more memory to mine than sha256. so I can iny advise you to try and reconfigure your miner params and clock speeds :-)

[/quote]Well, according to https://litecoin.info/Mining_Hardware_Comparison#AMD_.28ATI.29
you could expect 100-150 khash/sec.
If you found the max I value working for you, start modifiying the mem and cpu clock
Interesting enough on my card -6670- overclocking the mem doesn’t have much efect, so I run it at 780 Mhz only, CPU is overclocked ~ 10 %
but be careful, you card may burn
Sometimes you even get a better hashrate by reducing the GPU clock speeds and increasing the intensity parameter again :)
I recommend to check this: https://github.com/luke-jr/bfgminer/blob/bfgminer/README.scrypt
it’s from bfgminer, not from cgminer, but the configurable parameter and the corresponding effects are comparable.

i noticed you mentioned CPU is it possible to mine with GPU and CPU at same time if so how would i do it. I seen a link that was suppose to be for CPU mining but i am not sure if it did not work because 1. i did something wrong and am a total noob, 2. did not work because i am already using GPU to mine or 3. is CPU miner unlike the cuda miner in using for my nvidia gt 9500 where i essentially just clicked start ?
feel free to post screenshots of any steps needed to mine with CPU and my nvidia 9500 gt GPU

if you use cgminer or bfgminer you need to enable CPU mining during the configure step, when compiling the code. check the configure script in the source directory to find the parameter to be set.
Also I noticed, that at least bfgminer doesn’t do CPU mining, if it finds a GPU,what makes sense, as you can expect a hash rate of around 1.2 -1.5 khash only for cpumining, while any GPU gives hash rates of 10-600 khash,so that the additional hashes comming from CPU mining are less than the variance you have in the hash rates comming from GPU mining.
