You can lower fragments to 8388607. Result will be the same.

"intensity" : 26.7,  "worksize" : 12, "threads" : 2

If i add fragments=338033747 in config when speed up about +10 H/s

If you are not using the latest 1.6.4 version, but an older version < 1.6.0 please try first 1.6.4, and if the problem continues, enable logging.

Are you sure that you wrote all right?

I tried to mine Graft with but the miner crashes everytime after few jobs sent from the pool. Any idea how to troubleshoot this?

Using Win10 1803, SRBminer 1.6.4, amd adrenalin 18.6.1, 6*RX580 8GB Samsung memory. Getting a bit over 6.8 KH/s on CN-heavy, that's 1130-1140 KH/s per GPU.
"intensity" : 54,
"double_threads" : true,
Übermix 3.1
Memory 1340/1050
GPU 2065/880
Virtual memory 51200MB
and of course after upgrade of the drivers I used radeon settings to set the GPUs 1 by 1 to compute mode.

Interested in your setup and results with blockchain drivers.

Awesome, thank you . Now i can put the settings in the first post so everyone can see it.

Thanks, could you tell me the hashrate too?

Can someone with 550 and 560 cards tell me which config is the best for V7 and Heavy ?

Added info in tips section here on how to turn off crossfire and switch to compute mode.

Thank you...the compute mode did it, you allowed me to keep some hair on my head..lol...thanks again

Try 18.3.4 driver.  Make sure Crossfire is off and cards are in compute mode.  Avoid Windows 1803 build.

All of my 480/8 get 900 or better on 2 different rigs with this config.

18.6.1 is good for CN V7 on Vega cards, gives the most hash. While is worse on heavy than BC for example.
Amd stuff.. It is nearly impossible to make a miner that works good on every driver.

So that's why people shouldn't switch drivers every time a new one comes out, just stick to the one that's working.

Anyone noticed how miner1.6.4 and amd drivers 18.6.1 don't work well together on amd rx 580 on Heavy algo. I get half of hashrate than when using amd blockchain drivers.
Blockchain drivers are still the best strange how AMD couldn't develop new functional drivers in all this time.

I think I found the problem.
In the last line add a comma, like this:
   { "id" : 4, "intensity" : 28, "worksize" : 8, "threads" : 2},

Trying to run 2 rx480 8gb Samsung cards tried auto intensity, 56, 40 , 45....but I cant get these cards over 300h/s on heavy...running same cards on another rig hash 1000ish , increase virtual to 80k but still no go, any words of wisdom?

Check the temperature of all cards, are all going down or it is one only?
Set memory speed to 2050 MHz & test if it happens again.
