What is the combination of your cards and the hash rate?

What is the difficulty value?

For my 8 GPU 7990+7970 rig (5.6MH/s), the difficulty is 510 at the moment. Some times, it is 1000.

The total rejection rate is 8.9%. It is usually 1%. So maybe it is coin specific.

I have 1 r9 290x from Sapphire, puts out about 904kh/s with stock cooler and a little tweaking. I use cgminer.

What are expiry, scantime, and hotplug?

(btw if you could help me figure out why bfgminer crashes my computer, there's 25 pxc in it for you )

This is my cgminer config:

"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "0",
"thread-concurrency" : "32765",
"shaders" : "0",
"gpu-engine" : "0-0",
"gpu-fan" : "0-100",
"gpu-memclock" : "0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "90",
"temp-overheat" : "86",
"temp-target" : "83",
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "3",
"no-pool-disable" : true,
"protocol-dump" : true,
"queue" : "1",
"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"

(p.s. lol, litecoin is the most profitable coin to mine right now?! alt cleansing in progress, beware.)

That is because you use 7950. In order for 7950 to perform faster, you have to use 1 GPU thread and high intensity. The higher intensity, the more work is going on in the GPU. So it takes longer to finish one task, causing rejection/stale. For example, intensity 19 has double the amount of work going on as intensity 18.

After I found this out, I stopped purchasing 7950. All my new GPUs are 7970 or 7990. They use intensity 13 and 2 GPU threads, which is equivalent to intensity 14, which is 1/32 (2^5) of intensity 19. They are more suitable for fast coins.

Guys stop selling your LOT (lottocoin). It can't grow as a currency if you sell it. There are not enough buy orders to sustain the sell orders.

Out of the last 30 mining rounds, LOT only came up once, and the pool did not find a block.  Find someone else to blame for the low value of your latest favorite clone coin.

That would be epic.

I was just getting superb accepted/rejected ratios around 50:1, when suddenly over 70% became "above target" and rejected.

EDIT: Got better, then worse, then my difficulty spiked to 625, then it fell to normal and things got better again.

How are we doing on getting the site up and running.

Im getting close to 5500kh/s in rigs, but i wont run until i can make workers for them.

 

We are planning on tonight baring no setbacks! 

We want the new portal up as fast as you all do! Just gotta make sure everything is 100% before releasing.
