[JCE]Fast & stable CN/v8/Heavy/Tube/XHV miner, CPU+GPU, Vega56 1800+ RX580 1200+

[dragonmike]

Problem with my RX570 rig... miner crashes after init on startup, right after the pool sends the new diff. Haven't changed clocks from what I used with SRB. Any ideas/suggestions? Using tuned straps but nothing out of the ordinary.

My findings are similar to what some others have reported.

I tested TUBE on the latest version 0.33b5 on two different identical rigs, each with 6 x  8GB RX 580, with the only difference being one is on Adrenalin 18.6.1 drivers and the other is 18.5.1.

With each rig, only one GPU out of 6 reaches maximum hashrate (approx 1220 h/s), and the other 5 GPUs level out around 990 - 995 h/s. I have tried various multihash settings as well as other greeks but this issue remains regardless.

If I use the --no-warmup switch, 3 (sometimes 4) of 6 GPUs (for both rigs) will reach maximum hashrate (up to 1180 h/s) and the others will remain in the upper 900s h/s.

My GPU hash 0 h/s after 2 minutes...using auto config or manual, any help? (RX580 4g)

Too much overclock or undervoltage.

Latest version needs to fix... Speed on heavy algo isn't stable for a long time...
And what about cards with 3,5Gb of vram? On my Pitcairn 270X 4Gb(3,5Gb OpenCL) speed on heavy algo is almost the same as in previous versions, but fee more...

How long are you waiting for max hashrate?  I had found even w/ previous versions, that w/ a larger number of cards (6+?) dialed to max efficiency, I often had to wait way longer than the normal warm-up window to stabilize on max hash rates - possibly as long as 30min to an hour.  I would see the same behavior you are describing, where a couple of the GPUs (different ones every restart) would hash a couple hundred h/s lower for a while, before finally deciding to join the rest of the rig at the max hashrate.

As it would almost always get to the right level sooner or later, and then usually stay there, I wasn't terribly concerned.  Though at some point i did start wrapping the miner call in an auto-restart loop w/ a hashrate watchdog, which could sometimes get the rig to the proper h/r sooner.

Is there any known problem with RX570 (4GB) initialisation on auto mode?
Can anybody share a working manual config for CN_Haven algo please?

Here is mine:

Multihash 480? Wow that's quite a bit lower than what I was trying to tweak with. No wonder it wasn't even starting.
Ok so that seems to work now... however speeds are terrible. avg 270 h/s per 570. What am I doing wrong?

I have no clue.
Mine is mining XHV at 945 h/s with:
GPU clock: 1380 MHz
GPU voltage: 1000 mV
Mem clock: 2110 MHz
Timing from PBE 1.6.7 and Samsung memory.

Hmmm I think I have an idea, I might have left some CPU-config code in the file. Editing that away.
I assume the conf above is ths only parameters you've set? Nothing else?

EDIT: nope. Still doesn't work. Well, it doesn't crash anymore, but hashrate is zero.  

Also, to be sure: I've got a 7x RX570 rig. My GPU0 is IGFX. I assume I should then use -g 1,2,3,4,5,6,7 in start.bat and index should start with 1 in the GPU config file?

EDIT2: I think I'm getting there. Apologies, I seem to be talking to myself... but yeah. Removed the CPU parameters, and lowered multi-hash a little bit more. Now suddenly hashrates increase. It's a proper tweaking exercise, this miner.

@JCE: your "auto" parameters must be way too high for 4GB Ellesmere GPUs.

I don't know why this forum replaces my images by link.

Some possible explanations of your issue:
 - your card "Workload" value is "Graphics" instead of "Compute"
 - Crossfire is enabled
 - The index in your config file doesn't point the right card.

The JCE miner is provided with a file "probe.bat". You should launch it because it displays all the mining capable devices, including the graphic cards in their index order.

[dragonmike]

Merci Lermite!

No worries about graphics/compute & crossfire. Got all that covered in registry.

"multi hash" was definitely the culprit. Getting much better values now that I reduced the rates. 480 was failing so I went down to 416. All cards worked. Slowly working my way back up now to find optimal value.

On different versions of Windows and drivers there is different amount of free videomemory on cards. So you just must try to lower multi_hash parameters multiples of 16. F.e. 464, 448, 432, 416.
On heavy algo more multi_hash gives more speed. But if there is not enough videomemory, miner not always gives error, often it just significant decrease speed... This maybe Windows problem, when on start of miner it gives more videomemory than it gives it after launching, or something else...

I just started mining CN heavy with my old cards. At the beginning very unstable hash and power draw. After 10-15 mins it stabilizes. On auto settings I get for 390's -> 560 h/s (175W power draw, they are all -150 mV), for 280x -> 360 h/s (120W power draw, they are varios UV -100 or -60 mV). Are there any settings for the config parameters that can increase the hash?

Edit. After experimenting with the multi_hash, I got 390's -> 650 h/s and 280x -> 390 h/s.

I am trying out JCE for the first time.
Getting 1660h/s per card.
What would be the best config for Vega 56's on BittubeV2?

This is my config.

"gpu_threads_conf" :
[
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta":4, "index" : 0, "multi_hash":464 },
     { "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta":4, "index" : 0, "multi_hash":464 },
],


Thanks

Will there be a linux GPU version soon mate ?=)

Alpha 128, multi_hash as high as possible.

[JCE-Miner]

With the last version 0.33b5 i'm not that sure the best multi_hash is the max any longer. To be tested, but on my two RX560 one 2G one 4G, the 4G is no longer the fastest. And high values tend to make the hashrate less stable on RX.

Linux version: unlikely, by lack of time. I'm struggling at keeping the dev up and i still have to do support on the CPU version.
Again, little support today sorry

nVidia version (question i skipped before): very very unlikely, i dev in OpenCL, not Cuda, and nVidia's OpenCL somehow sucks.

I'm experimenting a very different implementation, JCE Hybrid Miner, with the AES job done by the CPU in a split second (because an AES CPU is basically an AES one-cycle asic) and only the scratchpad done by the GPU, with the requirement the CPU is aes-compatible, and the GPU memory relocated is above 4G (option in most BIOSes).
If it works, performance should skyrockets The bottleneck is the synchronization, which is fine on OpenCL for FPGA (like Intel or Xilix) but not on AMD GPUs.

I use alpha:64 and multi_hash:896 on Vega56 and i have 1700 h/s which is a 21% increase than previous version where i had around 1400 h/s.
Great work DEV!
Tnx for this great miner!

[JCE-Miner]

Nice, i'll publish that config in the Github documentation, that's just the best CN-Heavy mining setup so far (JCE+Vega56) in term of efficiency.
