Hi, I have rigs with 6 x p106-100 mining edition and they work just fine with 5.3b (on 382.43 driver version).
But when I update miner to 5.4c it simply doesn't start, miner closes in a second.

I tried updating drivers to 460.89 and 5.4c starts but shows me errors:

NVAPI error in NvapiWrapper.c:316 : -6  
Unable to load NvAPI: error 3
GPU1: unable to init NvAPI with bus ID 65536
GPU2: unable to init NvAPI with bus ID 131072
GPU3: unable to init NvAPI with bus ID 196608
GPU4: unable to init NvAPI with bus ID 262144
GPU5: unable to init NvAPI with bus ID 327680
GPU6: unable to init NvAPI with bus ID 393216

What's wrong? Should I either continue to stay on 5.3b and don't update or there's a better driver to work with p106-100?

Dear Mr.Phoenix, Hawaii card r9 390 8gb doesn't work on hiveos with phoenixminer 5.4b when trying to mine Ethereum... Will you modify kernel to fix this ? ty

update:

my second RIG having problem with new setting
GPU 1 at first try my RX480 get 26mhs... now drop to 9 mhs
GPU 1,2,3 stop at random after a few minute after run and miner crash
try with other miner i get GPU 1 run normaly speed at 26Mhs without crash

my other rig with same setting run normaly after 9-10 hour

maybe there are new BUG from Phoenixminer 5.4b....??

have done new install on my second (last) RIG

watching for 24 hour to check

I am very happy to see that there are new updates.
I'm going to try now and hope my rig can run mining again


update:

holaaaaa...
after 10 days left my RIG can't run with PM,
now with new update driver and PM its running without problem Allocating buffers failed with: clCreateBuffer (-61).

now run:

thank you @PhoenixMiner

The new beta version is ready. You can download PhoenixMiner 5.4b from here:

https://mega.nz/folder/OJ9BCYaD#osOU-PywjweHqQkux8rpbQ  (MEGA)

If you want to check the integrity of the downloaded file, please use the following hashes (you need the last file PhoenixMiner_NVRTC_Windows.zip only if you want to mine BCI with Nvdia cards under Windows):

The new features in this release are:

• New kernels for AMD Vega and Navi GPUs that are slightly faster when the DAG buffer is approaching or passing 4GB in size (the current ETH DAG is close to 4GB). To use these new kernels, you need to use drivers 20.5.1 or later under Win10, or 20.10.x or later under Linux
• Automatic re-running auto-tune as needed when switching to a different DAG buffer type (e.g. when switching from ETH to ETC, or back)
• Added support for the latest AMD Windows 10 drivers 20.12.1 and 20.11.3
• Fixed crash when trying to set -mvddc on very old AMD drivers (including the beta blockchain drivers from 2017)
• Other small fixes and improvements

Some notes on the best (or at least some of the better) drivers for AMD cards:

• If you have 6GB or 8GB card that is at least Polaris (i.e. 470/480/570/580, Vega, Radeon VII, Navi), you should run at least driver 20.5.1 under Windows 10, or driver 20.10.x under Linux.
• If you have 4GB Polaris card (i.e. 470/480/570/580), ideally you should also run drivers 20.5.1 or later. At the very least the drivers should be either 18.12.1.1 to 19.7.5 (inclusive), or 19.12.2 and later. Under Linux, drivers 19.x.x or 20.x.x should be OK for 4GB cards.
• Avoid using the 20.40.x, and 20.45.x drivers under Linux.

Please let us know if you have any problems or questions related to PhoenixMiner 5.4b.

Phoenix 5.3b so many stuck thread issue compare to last version much better in Eth

may be can help

kernel 1 ?

My workers stopped today, all 8 gb cl 61 not enough vram on hiveos

Hi ppl! I have an error when I try to use -mt 1 option. I've searched the forum but I haven't found a solution. So, when the -mt 1 is applied I get this message:

GPU1: Unable to set VMEM timing to 1 - error: -8
GPU2: Unable to set VMEM timing to 1 - error: -8
GPU3: Unable to set VMEM timing to 1 - error: -8
GPU4: Unable to set VMEM timing to 1 - error: -8
GPU5: Unable to set VMEM timing to 1 - error: -8

I have Sapphire Nitro+ rx570/rx580 cards.

  Remove the -straps command - it is not supported on Polaris GPUs. Then try mining ETC to see the normal hashrate (you need PhoenixMiner 5.3b) when the DAG actually fits in the VRAM.

You won't be able to mine ETH with full speed on 4 GB cards under Windows any more but it will be more like 20-23 MH/s with the current DAG epoch and will go down a little with each new epoch - you will need to let auto-tine to finish in order to see the final hashrate.

Your solution is the next:
1. win10
2. driver 20.4.2
3. patch by 'atikmdag-patcher-1.4.7'
4. switch to compute mode by 'AMD-Compute-Switcher'
restart and enjoy)))

ok,.. i'll try to update to win10

Windows 10 please....

also could be bad gpu or risers

go install AMD DRIVER ver 20.4.2

I also have 390's and serious troubles with them.
1. On Windows the hash dropped by 50% a long time ago due to drivers issue. There is no workaround for that known to me. And who would like to mine at 17 Mh with a power consumption 220-250W (at best with undervolted bios)?
2. On linux based OS with Claymore everything is fine but the miner will stop workig in a few weeks.
3. Practically every other miner I've tried - ethminer, nbminer, gminer and lolminer, half of the cards are not hashing under linux based OS. If someone has the patience and skills to run with Ubuntu 14 and Amd drivers 17, it may work at the end. But I prefer plug and play OS like smos or hiveos.
4. The only miner that can support different kernels is phoenixminer. With parameters -clKernel 0 -clNew 0 (i.e. the generic kernels) all cards are hashing, BUT, as the developer commented a few pages back, the stale shares are too many. If I mine with the default intensity they go over 20%. If I lower the intensity -mi 7, they drop to 10%, but still not good. For example, with Claymore I have the full 30 Mh with less than 1% stale shares. May be even below 0.1%.
5. For some reason smos and hiveos are crashing on start when I run a mixed rig with 390 cards and rx cards. Tomorrow I will try 390's with nvidia 1060 under hiveos, but I have no high hopes for this to work either.

go install AMD DRIVER ver 20.4.2

What driver version is that?

Update your driver.
