when Polaris came out, I remember someone modified drivers at the beggining.

I think you remember wrong, there were "blockchain drivers", but those were drivers
made by AMD specifically for mining

Think a guy named 'RobinHood' put out a hacked driver just a few hours/day or so before the official blockchain ones. Recall downloading it to test, then seeing the official ones before getting time.

Anyway, doesn't matter now!

Why don`t try benchmark mode for DAG 1 or so..

test it with:
EthDcrMiner64.exe -benchmark 2

it will use just ~1GB of ram for DAG

The problem is on driver level and it isn't related to DAG size - as far as I know. I tried to run a benchmark but the result is nearly the same (instead of 3,5MH/s I got 3,6MH/s  Grin Grin )

Yes the problem is AMD intentionally crippled the driver for the ETH algorithm, because they knew it would do nearly 60MH in eth mining and they would not be able to get them in gamers hands.

here we go again Cheesy
meh, as per last time, eventually it will be allowed by AMD
thats rough tho haha

yup, thats what I remember too, cause I did try them, later than blockchain drivers came out.

Currently running 54 MH, haven't started messing with timings yet Cheesy

Also claymore is still running this as old GCN code, he hasn't updated to Wave32 which should significantly reduce core load needed and reduce power to under 100 watts.

I am getting 53.8 Mh/s with some brief tuning in Wattman with driver 19.9.1 and Windows 10 Pro.  This is on an RX 5700 blower style GPU.  Using Claymore v15.0 to mine Ethereum.

After a few failed attempts and reboots, I am now stable with memory overclocked to 950, core clock is running between 1700 and 1740 Mhz at 940volts.  Temps are low 60's with fan running at 2400rpm (not loud at all).  It is pulling 180 watts at the wall, however.  Need to work on that!  No setting in Wattman to reduce memory volts, only core volts are available.  Still, not a bad start!

UPDATE> reducing the core clock down to high 1500's with core volts at 870 the watts at the wall are down to 160, temps are down, fan speed slower and it still mines at 53.5 Mh/s

NOTE> Any change to core clock during mining results in an instant freeze and reboot is required.  Other changes in Wattman do not seem to have the same result.  Not a fan of Wattman

I do use wave32 mode. During tests I tried wave64 as well, both showed same speed.

Please read Readme and FAQ in the first post of this thread before asking any questions, probably the answer is already there.

I'll release a new version of AMD Memtweak XL later today with latest driver support (Strap injection support for latest driver)
So you can play around on your Navi card Smiley

Cheers!

Hello.
I am a newbie and thinking of starting mining with these cards and need the help of the community.
Are the common PCI risers adequate for mining with these cards? Can I also use my asrock H110 mobo?

Thanks in advance.

I was able to get just over 1100 h/s in monero using XMR-STAK.  TRM didn't even recognize the GPU.  Not a great result for such an advanced GPU in my opinion.  I'll stick with ETH for now.  Would be nice if we could tweak the memory timings - that would certainly help on all mining.

No, we haven't ported our (TRM) asm kernels for CN (and variants) to Navi, it's a pretty big effort, and toolchain support is not there yet. I'm not even sure we'll port the kernels given that we predict a shit hashrate, much like the one you're getting with xmr-stak. The reason is the switch to 128 byte L2 cachelines in the Navi architecture. Modern CN variants (CNv8, CN/r) use 64 bytes, older variants use 16 bytes whenever they touch mem. AMD GCN used 64 bytes cachelines, matching modern CN variants read/write patterns - no overhead.

So, what happens with CN for Navi is that for every mem access, you start by reading 64 bytes, but the mem controller on the Navi card actually reads 128 bytes since it always must pull a full cacheline into the L2 cache. This effectively doubles the consumed mem bandwidth, and you see a hashrate matching a pimped 580 rather than a Vega 56/64. In any case, crap CN hashrate compared to Vegas is the result.

For ethash, you always load 128 byte chunks anyway, matching the new L2 cacheline size, so no problem there.
