cgminer Rejected as lowdifficulty

Question

I got an issue with cgminer constantly rejecting shares. How can I fix it?

Here's example rejection (note that Diff jumps - sometimes it's 6/1 sometimes it's 1/1) :

[2013-04-09 14:24:05] Rejected fe26cac1 Diff 4/1 GPU 0 (lowdifficulty)

Here's the .bat file I use:

cgminer --scrypt -o eu-stratum.btcguild.com:3333 -u MyUser -p 123

My OS is Win 7 32 bit.

What is your share difficulty set to in the btcguild settings? — Compro01, Commented Apr 9, 2013 at 16:48
I just tried 8-16 and 16-32 - both fail with the same result. What's weird is that I have cgminer setup on another PC with much better GPU and it works flawlessly there with difficulty set to 8-16. — MarcinWolny, Commented Apr 10, 2013 at 8:40
To closevoters: this question is on topic as per the current FAQ. If we want it to be off-topic we should clarify the wording there. — eMansipater, Commented Apr 29, 2013 at 21:07

I had this issue also the fix for me was adding--scrypt -o to the beginning so it look like this :

--scrypt -o stratum+tcp://stratum.scryptguild.com:3333 -u iwantcoins_nick -p nopw --load-balance

Also worth trying to tune your other GPU settings, this will increase your hashrate, and hopefully reduce your rejected share rate.
