SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[doktor83]

Does this miner works with the old R9 280x ?
                       
Anyone tried?

yes it works

SRB is best for my 4xR380 (CN7 - 740H/s per card - 1050/1600Mhz) but very unstable: "application has been blocked from accessing graphics hardware".
The same problems as default settings (1000/1500Mhz). Driver 18.5.1 whql, Win10 (1803). Claymore 11.3 is OK.

What settings for RX580 8Gb? I got only 820H/s in CN7 (intensity 60/8/2, 1430/2200Mhz).

Try with 1 thread, i had better results with 1 thread when testing on 380 4g.

56/8/2 is ok for 580 8g.
Are you using a custom strap? Memory brand?

Hi! Are there plans to support the purk algorithm?

Nope, it's not cryptonight algo.

Thanks, now intensity 56, thread 1 - 700H/s (R380 2g, samsung) looks stable. (previous 31/8/2 - 740H/s)

RX580 in default (no custom straps/mem). But not bad in Heavy algo - 1000H/s

The original question from UAGet was not inordinate.  It was a reasonable question.

When i was testing r9 380 with double threads i could not go beyond intensity 28-29, it simply always crashed the driver.

so i checked out the opencl kernel of purk and it has nothing to do with cryptonight algo.
That's why there are wildkeccak miners for purk, not cryptonight miners.

at 31 intensity works, but after 4-5 hours driver crashed, (the same as 28-30 intensity).

Try to adjust your OC, most instabilities I've had could be solved by throwing more voltage at the cards or reducing the frequencies.

Yes, i tried OC, other miners, algos, etc.(claymore pow7, zcash, ethash is OK). This problem (crash driver) they only cards conected to splitter-PCIe:

how do you uses this miner with undervolting? With Afterburner? Because it does not support cvddc in config.

[abg00]

via bios editing

Or overdriventool. bios editing is a bit too invasive.

Hello,

We launched MoX few days ago with a new variant of CryptoNightV7 which consists of CryptoNight Lite and a tweak variant.
I'd really like to see the support added into SRBMiner as well

Please contact me about that !

Have a good day

Our github : https://github.com/mox-project/MoX
and here is the tweak in question :

#define VARIANT1_1(p) \
  do if (variant > 0) \
  { \
    const uint8_t tmp = ((const uint8_t*)(p))[11]; \
    static const uint32_t table = 0x75310; \
    const uint8_t index = (((tmp >> 8 ) & 6) | (tmp & 1)) << 1; \
    ((uint8_t*)(p))[11] = tmp ^ ((table >> index) & 0x30); \
} while(0)

solve trouble with variable rate rx 560 4 gb card on heavy

12 gpu rig work with 4 gb ram and 60 gb swap. rig work but with variable rate
change swap to 90 gb and rate stable high

thanks for this info, i will put it on first page in tips. 90gb insane for 12x4gb

Vega FEs are allergic to 18.3.4 and I'll get less hash-rate on Alloy/Heavy and CN7, on Alloy there is alot of STALE shares too, so the only viable driver is 18.6.1.

Results for a rig having 5 Vega FEs SRB Miner 1.6.4:
driver 18.6.1
CN7  = 11060 H/s
Alloy = 5670 H/s
note: Mining Alloy, on DevFee we get miner crash or error

driver 18.3.4
CN7  = 10900 H/s
Alloy = 5580 H/s
note: Mining Alloy, there is a lot of STALE shares.

Results for a rig having 5 Vega FEs SRB Miner 1.6.1:
driver 18.6.1
CN7  = 10910 H/s
Alloy = 5630 H/s

Hello,

I was wondering if you could share how you setup your FE, I have one in which I cant seem to get working. I am trying to mine bittube with no success and if I do get it running it draws too much power.

CN7  = 10910 H/s
Alloy = 5630 H/s

=========================================
So in conclusion:
18.3.4 won't work for Vega FEs. For Alloy we have to use 1.6.1 and we get similar hashrates as blockchain driver.

Edited: The said crash/error occurs not on DevFee but right after when resuming!

Stales are not a problem if they are accepted,i guess the difficulty on the pool you use is low, and the pool sends jobs quickly, so that is why you get a lot of stales, but if they are accepted then you have no problem.
Also could you turn on logging (use --logfile log.txt in bat added) maybe i can get more info on the crash ?
If i understand you correctly only on 18.6.1 is the miner crashing, on 18.3.4 it isnt ?

Yes, I'll do this and see what we get. Regarding the drivers, I think 18.3.4 is just not working for me, even on CN7 I get lower hash-rate simiar to what I used to get on Blockchain driver about 150 H/s less or 50 H/s less on heavy/Alloy, but 18.6.1 has been very stable for me. So I avoid 18.3.4 totally. As for heavy/Alloy algo while using the SRB 1.6.4, I get GPU crash right after DevFee sometimes recovers after resetting the miner but other times I have to close the miner and restart it manually. I noticed this happened on 1.6.1 too but apparently less often. I don't have a clue what the cause could be, but I guess it might be something to do with change of algo from Alloy to DevFee and back. Unfortunately I have not had the chance to try any other heavy algo yet. I'll set the log and see what happens and come back. Thanks
