Just found this one
http://glx.poolofpools.com/

But it should still connect right?
Or it just processing things too slow to come up with any valid shares?
The Invalid count raises pretty quickly, so I thought the settings were fine.

Hello,

I am having some issues mining LTC...

Win 7 Pro, 64 bit.
2 x NV GTX 570 cards (i know, I know...but lets not get into why AMD is better, these are the cards I have right now)

I have guiminer-scrypt set up like:

Reaper Miner
Host: notroll.in
Port: 6332
username: (my username)
Pass: (my password)
Thread concurrency: 1
Worksize: 256
Vectors: 1
Intensity: 10
GPU Threads: 1

I click start, GUIMiner reads "Connecting" and begins racking up Invalid shares.
It never reads "connected", it just continues gaining Invalid shares, no Stale or Valid ones.

I can only offer advice on the PSU.
Do not go cheap when it comes to powering your rig.

bump 

If this is still going on, thank you!!!

What info should I provide?

Bump, anyone?

Dakota,

That was happening to me at first because I had a CG miner configured instead of a Reaper miner.
When I changed to Reaper it began working, except then I ran into my problem above.

Regarding the program minimizing to your notification center, that is an option you can enable/disable within configuration.
Some people don't want it cluttering up their taskbar when it is running.

Hello,
I am having some issues with litecoin mining...

I have guiminer-scrypt set up like:

Reaper Miner
Host: notroll.in
Port: 6332
username: (my username)
Pass: (my password)
Thread concurrency: 1
Worksize: 256
Vectors: 1
Intensity: 10
GPU Threads: 1

However after I click Start I just begin racking up Stale/Invalid shares...
Over the past 20 minutes I have gained 2 Stale/759 Invalid shares.
And 0 Valid.

Any help would be appreciated.

To add, this also occurs when I attempt to mine for LiteCoinPool, where I have amassed 0 Valid, 0 Stale, and 212800 Invalid Shares.
Wtf

This is affecting me as well...
Any other ideas besides "Don't use GUIMiner"?

I start at about 120MH/s per card (2 cards)
Then drop to almost nothing after 10 minutes, like clockwork.
I can start one worker 20 seconds after the first and it will drop speed 20 seconds after the first one begins to drop.

Once I stop/start the workers again they are back at 120MH/s...
