Litecoin on 5850 Kh/s incorrect

[Clearfly]

Can anyone explain why when i mine litecoin cg-miner is reporting 340Kh/s yet on the pools it's only showing about 16-20Kh/s.

Tried different pools, notroll.in, suprnova.cc, coinatron

Yea, I noticed that too, but not quite to such an extent.  I call it the hidden pool tax.

The pools all have a ramp up time for measuring your speed. I've mined on most of those and it takes time for your pool stats (which are typically a 24 hour average) to catch up. If you're quickly hopping from pool to pool without giving it the necessary time, this could be the culprit.

at least its telling you something.. 2 different pools still show im not doing anything at all, even after about 5 hours.  no reported shares, no reported speed.

I understand the pool hoping thing, but i've been on notroll.in for 12hours and have only about 220 shares. About 0.07LTC

After 12 hours it should be nearer 1.5LTC

Edit:

Using CG-miner
cgminer --scrypt -o http://notroll.in:6332 -u **** -p **** --shaders 1440 --intensity 17 --worksize 256 --lookup-gap 2 -g 1 --gpu-engine 850 --gpu-memclock 1000

Kk i think i know what the problem is.

CG miner is showing the difficulty as 6.59M which is the Bitcoin Difficulty not the Litecoin difficulty.

How do i change this?

Not, it's correct.
multiply / divide by 65535.

I'm also have this problem , on give-me-ltc and tc.kattare, only showing 15 kh on thier site , reaper shows 300khash , after 12 hours don't even have 1 LTC.

I sussed it by adding the option:
--thread-concurrency 8192

The value must be divisable by 64.

These settings are set for two cards. Remove the settings to the right as explained in above post for one card.

Here is for one card. My cgminer.conf file. I get 400 khash/s with these settings, and the pools I use read almost exactly what my cards put out.

Code:

{
"pools" : [
	{
		"url" : "pool1:port",
		"user" : "username.1",
		"pass" : "password"
	},
	{
		"url" : "pool2:port",
		"user" : "username.1",
		"pass" : "password"
	}
]
,
"intensity" : "19",
"thread-concurrency" : "5760",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"gpu-fan" : "0-75",
"gpu-vddc" : "1.088",
"gpu-engine" : "0-944",
"gpu-memclock" : "1180",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "0,0",
"temp-cutoff" : "0,0",
"temp-overheat" : "102",
"temp-target" : "100",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-threads" : "1",
"log" : "5",

"scan-time" : "60",
"scrypt" : true,

at least the pools like litecoinpool, notroll.in, and coinotron use an approx 10min avg.

OP, give it at LEAST 10-15 minutes and then check the hash rate in the pool.

THEN, understand it is an AVERAGE, if you have 1200khash showing on cgminer, you can see anywhere from 950-1500 at the pool, depending on miner luck in finding shares.
