Claymore's NeoScrypt AMD GPU Miner v1.2 (Windows)

[Claymore]

wow, wonderful, RX470 speed?

I get 900KH/s on stock "RX470 red devil" card with "-powlim 50 -a 2" options.

Both my ZCash and Neoscrypt miners will be AMD-only, sorry.
There are many NVIDIA devs here and they already released appropriate miners.

Your miners are the best out there. Keep up the good work.

Ok testing with vega 56.  It really seems to be a power limit problem.  With no real tweaking, just power limit on a stock 56 GPU, I get.

190w -19pl, 1300
235w 0pl, 1450

So, yes PL + 50 will get you good speed...but at an ridiculous power usage.  This is stock 56 though, not soft modded.

Agreed, my watercooled Vega64 at stock clocks takes 500W to show 2200KH/s, it's crazy. Though it takes similar power in dual mining too.

2x sapphire nitro rx vega 56

 160watts at wall  1500k/hs  -19 pl stock clocks

im told the fan on the standard vega pulls 30watts on its own

the nitro has 3 fans and its hardly hitting 50c

sapphire rx560  391 k/hs  not sure of wattage atm

[Claymore]

Anyway, now AMD is not worse than NVIDIA in NeoScrypt mining, let me know if you can get 2200KH/s from single 1080Ti

Did anyone test how much undervolt is possible going from stock card settings for stable mining for any of these cards for neoscrypt?

[dragonmike]

It'd be interesting when we get more data from users here, especially when it comes to optimal clocks to use.
Personally I'm trying this on my Vega56@64 rig. At -25 PL and Cryptonight clocks (1408/1115) hashrate is approx 1550Mh/s per card (using blockchain driver). The whole rig is drawing ~1450W at the wall in the process. No idea how stable that is in the long run.

EDIT: Claymore, have you experimented with clocks at all? Any approximate sweet spots you can advise?

wow, wonderful, RX470 speed?

I get 900KH/s on stock "RX470 red devil" card with "-powlim 50 -a 2" options.

I'm running drivers 18.2.2 with my 570/580 cards.   the -powlim 50 option doesn't seem to work

"Failed to set new Power Control treshold for GPU #0"  .. that's exactly the message i get... spelling error and all.

No, I use stock clocks in my tests.

I use 18.2.2 and -powlim works fine with my RX580. Anyway, you can try to use AB to set power limit.

[peterboy1]

wow. this is great. i hope for more algos from you in preparation to these asics and pos thingies.

Thanks for your help.  Figured it out afterwards.  the problem wasn't your code, nor AB.  my one 580 is an OC version and it's power limit is coded to be 30 max.  setting -powlim to 30 or less worked fine.

nice!!!
More algos for the best miner around!!
Congrats Claymore for the good job!!

vega has to be softmodded with power play table mod to reduce power or itsa hog

all my vega 56 and frontier cards are softmodded and do 40mhs eth 2500 blake at around 200ish watts

Not tried neoscrypt yet tho with this new miner

[rednoW]

Just tried this with my 2 vega64 and 1 vega56, xmr-based setup 1408/1150@900mV
vega64 is 2.1 mhs neoscrypt each card, vega56 is 1.9mhs.
Delta between idle and mining modes for 3 cards is ~750watt, so ~250 watt per card.
Good work, Claymore! ))

we are not far away, my 1080 ti gives 2000+ with latest excavator and just below 2000 with modified hsr...

nevertheless, it's good to have a decent amd neoscrypt miner, thanks
(I have different brands & models of cards, more fun....)

come one mate because there are other miner out there not means equality is same, plus more choise always is better & it can create a good dev competition my be in a pozitive way ... personal after i was use your Eth one damn i can say i wish you to change your mind & make Zcash & this new Neoscrypt supporting Nvidia to

but probabil maintain AMD & Nvidia on same equality is not easy task ...

anyway hope to change your mind & make a lot ppls happy

Cheers & thx

That sounds quite good. Would you mind sharing your overdriventool settings?
I am limited by my PSU (EVGA 1600 G2) to run these speeds but maybe I could get somewhat closer with some tweaking. These are my settings (although they won't mean much if I gimp them with -25 PL...

I posted my reg-file some time ago in vega thread, don't want to repeat. You can find it ...
I use old 23Aug blockchain driver.
I never use PL for downvolting, only p-states.

In your example I don't like 950 and 1000 mV settings for memory, they shoud be the same with corresponding P7-state (900 or 905 mV)

[MetalHelmet]

Oh, if you calculate the increased difficulty that will come, the only choice is ETH of course It seems I just waste my time with new miners...

Don't think so...
1. Nicehash will add this miner for sure - and on some spikes of high demand for Neoscrypt Nicehash Legacy miner will switch even "reds" to this algo (using your new miner which gives comparable hashrate )...
2. Autoswitch beatween algos on Miningpoolhub with  also can use it
3. ETH -> POS , miners goes to ETC / Pirl / ... and diff rise - so some of them will go to Neoscrypt in search of better profit


Anyway - new decent miner on "non-red's" algo - is a good job.
