CGminer - Invalid Nonce - HW error

[Mathrian]

I am attempting to mine in the Deepbit pool with CGminer and I get a repeating Invalid Nonce - HW error. Does anyone know what that is, what it means, or how to fix it? If Anyone could help that would be great.

Anyone have any idea what causes this?

I had this same problem for days when I first got started.  I solved it by completely removing my ATI driver.  I then installed the SDKand ATI driver and all worked well after that.

I even swapped hardware thinking I had a bad card....

Good Luck!

Well damn. Im pretty sure I've already done that, but I may have to try that again. Im getting all sorts of errors regarding hardware from everything but the BitMinter Client And I would rather go with a proportional payment method, or possibly go into litecoin mining.

Try turning down your engine and or memory clock. You can do this from within CGMiner.. use <G> then <C>hange settings.. GLuck.

I agree, try different engine and memory clock settings. Sometimes the ratio between them will make a huge difference in performance and get rid of the errors. You did not say what cards you were using which makes a big difference on settings.

Hi All,

Complete cgminer newbie here and am getting the same error, and the pool has only accept three share with one stale. Scratch that, 4 shares 1 stale, so it's accepting some, but still a hell of a lot of errors.

Win 7/32bit
Gigabyte 7970
Catalyst 12.8
Currently installing AMD SDK 2.7 to hopefully solve the error, I'm running cgmminer 3.1.1.

Does anyone know of any working software combinations for my setup or to get cgminer 3.1.1 to run with my 7970?

Any help is appreciated.

Cheers,
Jeff

If your looking at running cgminer on any pool with amd, there are many guides out there, just pick a currency such as LTC Gpu Mining guide, and crytocur.com should be able to help.

i'm getting this, too, on a dual card setup

[bt_spectro]

In my case, this error was because something was wrong with the drivers. I fixed it by completely removing drivers and installing 12.8

[plonk420]

i can't do that as i'm attempting to also mine with a 7790 :/

Was getting "Invalid Nonce - HW error" mining LTC with 7950 and 6950. Fixed by changing thread-concurrency.
cgminer 3.1.1, Win2k8 r2, Catalyst 13.4

[plonk420]

changing to what settings?

changing to what settings?

Looks like unique to the card/system/magic. Check LTC hardware comparison wiki page.
On one of my rigs - 7950 44000 works best, 6950 - 12672.
But was helping a friend to setup his rigs, those values were not working at all..
I've read somewhere thread-concurrency should be n*number_of_shaders, no idea if it is true, but I would start there.

i'm assuming i separate each card's settings with a comma like you do Intensity?

Have you tried intensity of 13? worksize 256 g 2? Trust me try it out.

[plonk420]

--worksize 256 -g 2 crashes CGminer, as does --worksize 256. -g 2 simply brings back the Invalid nonce

[Kaepora]

--worksize 256 -g 2 crashes CGminer, as does --worksize 256. -g 2 simply brings back the Invalid nonce

some people including me have experienced a weird issue where you have to st the intensity to 13 or less because we get errors. What intensity are you using?

[plonk420]

i started with intensity dynamic and 8 (my usual). just now i tested 13 with -g 2 and worksize 256, but it still crashed.

ah well, i'm NEARLY back to my normal hashes with Phoenix2 (5870) and CGMiner (7790). just 10 Mhashes short of 5870 by itself!

Can I ask what might seem a really novice question? What is the litecoin.conf files purpose created in the app directory for litecoin mining? Does it allow access to that port or something totally different?

Thanks,
