All my cards are doing less on BTC then they did on LTC

[qiuness]

Hi,

I decided to look into BTC mining for a change, so i`m up to date.
Tried to setup cgminer on BitMinter with the following settings:

cgminer -o stratum+tcp://mint.bitminter.com:3333 -u User_worker -p xxx --gpu-fan 55,55,60 -I 18 -w 256 -g 1
This resulted in some kind of bug:


I figured out that the intensity was the issue. With 9 my cards starting hashing. They go up to 14 but @ 14 the hash rate jumps around quite a bit.
After reading multiple threads, i heard that usually BTC has higher hash rates then LTC but this is what i`m seeing regardless of -I 9 or 14

LTC 3x6970 = 1415 KH
BTC 3x6970 = 1181 MH

I swear i looked around quite a bit, but apart from overclocking i`m at a loss
I appreciate any help

K stands for kilo.
M stands for mega.

Hope that helps. :p

(they use different algorithms, which is why hashrate is different)

... and 1181 Mh/s is equal to 1181000 kh/s
