Very Strange thing happened.

I switch from microcoinminer.exe to Cgminer.exe 3.7.2 to mine worldcoin, and my first 280X card slow to 500kh/s

I have 2 pc with four 280x cards in each. Both pc's first card slow down. Other 3 cards in both pc remain 750k. (no overheating issue, no HW error)

I did reboot, reinstall 13.12 driver, reinstall cgminer, reinstall cgwatcher. nothing helped.

It seems that microcoinminer has changed some settings in my system and it affect cgminer.

any help?

You can check engine/memory clock of the card, maybe changed by the miner, if correct try to turn everything off instead of rebooting.
Wait a minute an turn on and try again.

Thank you and Lexa on another post! Im an experienced miner the clocks and delete .bin was the first thing I did before I reinstalled everything.

I got it fixed, but I can't explain why this is happening:

The microcoinminer.exe screw up the "worksize" for cgminers on all my PCs.

I used cgminer.exe -w 128 for all my gpu cards. Worksize 128 usually give me lower khash/s but Higher WU. You know, only WU matters.

I use -w 128 for microcoinminer as well, and it is still working fine as I just tested. But I CAN NOT USE -w 128 for all my other cgminers anymore.

As soon as I change cgminer -w into 64 or 256, My first Video cards will become normal again pumping 740KH/s. If I use -w 128, my first video card will get sick again.

This have never happened before. -w128 was my magic number for long time, until yesterday I run microcoin wallet and solo with microcoinminer.exe -w 128.

I was guessing the microcoinminer wrote a secret setting in my system or amd drivers config somewhere.
