no one is sharing since they want to mine all those UTCs
Well, I was getting 135Kh/s before. So far I managed only 30Kh/s withouth HW errors. =( I assume that's not optimal. So until I can get higher, I won't be posting any bad configs. I'm in the same boat, only I couldn't use the suggested settings last time either. I had to run a lookup-gap of 3 with my 3 290x/ 1 290 rig. Now I can't seem to get all 4 cards to run again, even with a lookup-gap of 4 as I can't raise the thread concurrency high enough on each card to get rid of the HW errors on all cards before I get the Error 4: cannot enqueue...... The cards I can get it running on are running at about 40% of my old hash rate. The most I can get running at once are 3 of the 4 cards. I can get those running at 55% of old rate with no HW errors. |

Thirtybird could tell you better than me, especially if you are using his miner, but try upping your lookup gap 1 and your TC the same percent% e.g. -- lookup gap 2 --> 3, raise TC 33% and see what happens. |

N factor just kicked in. I started getting HW errors.
Yep, HW's flying all over the place Alrighty, then, lets get this party started :-) Adjusted my miners ahead of time - mining perfectly fine without HW errors  x2, |

so was their an N factor change or not ? mine are still running the same as before ??
was already running TC 65536 with 4 x GPU threads ... looks like it was compatible with N factor change

Mine were too during the last N-factor change until I restarted my miner, at least it said they were. Turned out everything was HW errors, it just didn't show it until restart. |

MSI 7950 = 36kh no HW (1030/1250) I=11 .Anyone have better setting?

still bugging out the HW's on the 7950's though I'm getting them rarely, so hopefully close. seems they are in the 45-48 Kh/s range. I'll keep pluggin away

Though I'm close, I'm using 4 different TC's for each card, my setup will be of no use to anyone for 290x, or perhaps one of the 4 might help 1 of 4 people... who knows.

Ye many miners may have to increase system RAM, hoping I can squeeze by with 8GB and 3 GPU; gonna be close if so. edit: think I'm at 0 HW's!! woot |

Looks like I cannot mine without more RAM too, this change is quite dramatic. Though I'm close, I'm using 4 different TC's for each card, my setup will be of no use to anyone for 290x, or perhaps one of the 4 might help 1 of 4 people... who knows.

I'm now at 56KH/s for each 280x accepting shares. Averaging 50 WU each, But I got 1-2 HW errors on some and 0 on some others. Not perfect but close! My 4 x 280x rigs only have 4GB RAM. I just had to raise the swap file to 32768. Still tweaking.... |

I have 3 running without HW errors right now, can't pull in the 4th. |

As a temporary fix to get your rig running,
lower the intensity by 1 and reduce your total thread concurrency by a number
equal to the shaders count on your card.
Example: a 7950 card has 1792 shaders so the current TC should be 16384-1792= 14592
If your rig is still showing everything running normal, this is a false positive,
restart your rig and apply the new settings.
This is also a good time to check your virtual ram setting on windows systems
and set that at a size 3 or 4 times of what windows have set it at.

On a 4 gpu rig, lowering my TC actually increases my HW errors. This has been true since the last N-factor. |
