i am facing this problem

http://i64.tinypic.com/j9pw02.jpg

check out GPU1 H/S

i tried fresh install drivers with DDU, and tried with diffrent cards also same problem. my 1 gpu always give me bad hashrate also check afterburner ss. and i also tried diffrent pool. but same problem. even i tried with
GA-970A-DS3P motherboard

and i tried with 5 rx 470 cards also and tried 15.12 drivers too

my config

MB= gigabyte GA-990FXA-UD3 R5
RAM= 8GB
VIRTUAL MEMORY = 16GB
PROCESSOR= AMD FX6300
1200WATT PSU

Just put screen on card running slow and put it back on preferred card when card is running properly! Wink

i m not understand u bro. pls explain more

This usually happens when pc reboot and miner restarts. I remove HDMI cable from the usual card and insert it into card that's hashing low, hashes will start to climb on card and than I put HDMI back on coolest card. I used to uninstall driver, but that's a waste of time.

If I were you I would do a series of tests to find a culprit by method of exclusion.

1. Can you do 4 tests: disconnect 1 card and run 4 other cards in a combination where you can exclude every card. If you are getting full speed on every card then it means that the cards are fine.

2. Do the same for all risers. Exclude 1, run 4. If you are getting full speed on every riser then it means that the cards are fine.

3. If tests 1 and 2 successful you need to try another PSU with more amps on 12V line. Or run that card from another separate PSU.
