[AMD] New AMD RX Graphics Cards of 2019 - RX 5700 / XT, RX 600

[dogedood]

What driver/kernel versions have decent hashrate using phoenixminer under Ubuntu 18.04 or 20.04?

[jessyj48]

Rx5700 and RX5700XT are one of the best AMD graphics card for mining nowadays and I still have some respect for AMD VEGA cards as well but the problem with RX5700s are high temp, for longer life these cards aren't the best and also if you are from a hot country Nvidia cards are best for you, I prefer RX480 or RX580 Amd cards over these RX5700s, they are way too hot like 80oC to 90c that's too high.

Nah they are good, more heat output more efficient they are in winter Love em when its turning under minus 0 C

new rx6000 series aka big navi teased, perform between rtx 3070&3080, at this point looks the gpu same route as rx5000 series
hope they running wider memory bandwith, fpga gaining more advance in the recent years, compete with gpu in mining, specially in compute performance rather than memory algo

Same reason why I'm against this RX5700XT, I ordered one from Newegg with double fans but they are too hot for my liking, it feels like the card will die very soon, I have no confidence mining with this card around the clock ( full 24hrs/ day ), some said to get the variants with three fans but they are way too overprice, got mine around 337$ but double fam variants are 449$ or more.

Looking at Moore's Law is Dead video, it seems the 6900XT will basically be double the 5700XT. So I would imagine double the processing units. The bus should be wider by 64 bits at the minimum and it will have 16GB of memory, but it probably won't be GDDR6x nor will it be HBM2.

So before tweaks it would probably run 100-110MH/s and with best optimizations after a month or 2 perhaps 120MH/s if pushed on a card with excellent cooling. The revised architecture should help decrease wattage but on a card that "big" you'll still need a massive cooler, so I would guess $800+ for a decent card.

According to his sources 5700XT is currently stopped in production for this big Navi.

That's if the memory bus allows it.

Hi DDesignE

Did you get Ethminer to work with RX 5700?  I tried v0.19.0-alpha miner but the miner shut down.  Please help.

Thanks

Hi guys again,

so, I've been messing around with the Ethminer Opencl Kernel, and I think I found out what is wrong with the RX 5700 family for mining ETH on OpenCL 2.0:

(Gonna need some help fixing it)

Let's Start:

After you download the new release's source code here:
https://github.com/ethereum-mining/ethminer/archive/v0.19.0-alpha.0.tar.gz
Extract it and find the kernels/cl/ folder,
Edit the ethash.cl file, change this line(236):

Code:

    mix = fnv(mix, g_dag[buffer[lane_idx]].uint8s[thread_id]); \

to this:

Code:

   /* mix = fnv(mix, g_dag[buffer[lane_idx]].uint8s[thread_id]);*/ \ 

compile and run the miner!

That line is responsible for bottlenecking the hole code!

I am able to achieve 300+ MH/s without that line of code!
(LOOOOL not mining properly, of course, I get only rejected shares!)

So:

My thoughts on this, and after some testing, the problem is MEMORY ACCESS!
let's get back to the code:

Code:

    mix = fnv(mix, g_dag[buffer[lane_idx]].uint8s[thread_id]); \

if I change

Code:

buffer[lane_idx]

for a defined value eg. '0',
It runs @ ~80MH/s (I assume It's the real Speed),
but of course again, REJECTED SHARES, because

Code:

buffer[lane_idx]

is supposed to change according to 'lane_idx'!
Bottom line is, fetching this piece of code's value from memory is slowing down the hole thing!

Conclusion:

I need Help, since I'm no ETH nor OpenCL Expert...
We can assume from this the Theoretical Seed of ~80MH/s for mining ETH on the RX 5700 XT!
(not bad, but I was Expecting 100+ MH/s)
(maybe with specific optimizations, driver upgrade, etc, we could get better performance)

I have an XFX 5700XT Triple Dis, power consuption 130W in gpu-z no matter what i do. If i turn TDP down more than -28, than hasrate drops a lot (with gpu clock) and of course Power consuption as well.

My Sapphire 5700XT do work -40TDP with 50+MH.

Anyone has the same card (with same issue)

solved

I bought a new card, RX 5700XT Gigabyte, I can do 53.5 with 105w 1280 cc, 735mv, Memory at 1870mhz
The core temperature is very good, 60c to 65c, but the memory temperature is 102c  

is it normal to have such temperature at memory? I know these new AMDs are hot, but never seen this temperature on my GPUs

I've just signed up to answer this - recently bought a Gigabyte RX 5700 XT OC for a good price in order to mining with it, and I get exactly the same memory temperatures under mining load when running the default fan profile of the card. I can get the temps down to 96 degrees if I raise the fan profile up to 80% (which keeps the core temp (non-junction) at around 58 degrees) but it sounds like a jet engine. Having done a fair amount of research on the subject through various forums and articles, it does seem as though this is standard behaviour for these cards when mining or performing memory intensive workloads, regardless of the model, and that the memory temperature reported is a 'junction temp', not the edge temp. I've noticed that under more normal gaming loads (e.g. 3dmark) the mem temps get up to 80 degrees or so with the standard fan profile so it does seem to be the mining that really pushes it higher.

Having owned a number of other graphics cards I still think these temperatures are too high versus what I'm used to seeing normally but maybe the true junction temperatures in other cards aren't reported in the way that they should be. What rx 5700 xt models are other people mining with? Do you see the same temps on sapphire and powercolour models? From the anecdotal evidence I've seen on other forums, these cards have similar temps in the same scenario.

Hey there...Just picked up a Gigabyte 5700 XT OC...Currently running 850 1300 (120 watts in Phoenix miner 5.3e software) and the mem at 1820...I got the mem temps down to about 88 on the highest card by forcing it to run at about 45% constant.   Problem I'm having is that I can't get a stable setup over 1820 ish on the mem...Which gives me about 52.6 mh.  I am running a rig that had an nvidia driver in it but did the DDU 2x.  Curious what your clocks are and what miner you're using.  Are you guys on Windows?  

Have you tried the Bios mod?  Appears the links to the 3.04+ flashing software on Igors site are dead...

@rdlduffy try a fixed 45-50% on the fans and see how it looks.

ive got core at 1390 mem at 920 (for windows that would be 1840...im on linux) voltage at 0.750 (may show as 750) mvdd 1325 and mvddci 0.8 (or 800) nets 53.25mh at 104 watts. been stable for days...i have not yet modded the cards bios.  Mem temp is 88 and fans are going  30-50% Asic temp is 58.  wattage can probably reduce a little more say to 90 but for now happily mining away.

With my Gigabyte I'm using 70% on fans to keep memories at 92°  It's very hot in my country and the only solution I found is to put fans to work hard
My Gigabyte is rev 1 and I think this is the best version, I'm getting 55Mhs right now on Phoenix, stable and without any restart, with 107w on software (no biosmod)

I bought an MSI 5700 Mech (non xt) and I'm trying to tweak, but it's not good as my first gpu, only getting 52Mhs, with 119w and not very stable yet
My gigabyte accepts 715mv but my MSI only 800mv to be stable

Thinking about modify the bios on this one

XFX 5700        750mv=+53mh/s=  84W logiciel
--no XT


very difficult to understand this GPU.

Thanks for that Dowper, is that the method you used?   I've seen other vids of them talking about using 3.04+ to flash from Igor's site, but those links appear dead at the moment.

The mem temps I reported earlier were when running the card all at stock, in a case with not great airflow and mining on Phoenix miner. I've now put the card in my mining case which has better airflow and am running it underclocked w/ power tuning. New clocks are as follows:

gpu core 1247mhz @ 836mv
mem 875/1750 (default) @ stock voltage

power limit -35
fan speed @ 67%
power consumption: 119w
hashrate: 50.5 MH/s

Using the above settings the memory temp stays at 90 degrees under load. I can get it down to 88 degrees by raising the fan speeds above 80% but the noise starts to become too loud. This is the best I can get on the memory temps on this card (gigabyte rx 5700xt OC) when mining. Given that I think these temps are too hot I don't want to raise the memory clocks any higher and I'm happy with hashrate and power consumption as it is. I've just upgraded from an rx480 4gb (which won't support the DAG size at the end of the month) so it's a big step up from that.

As mentioned previously running the card under normal gaming loads the memory doesn't get near these temps with a custom fan curve so obviously mining is taking it's toll heatwise here. The GPU hotspot temps are max 65 degrees so more than fine there. I imagine you'd get better memory load temps with the powercolor red devil or sapphire nitro cards but for the price I paid for this one (£330 brand new) I'm happy with the performance.

[screamopilla]

Update: The addition of two top mounted 120mm exhaust fans has brought memory temps down by an addition 2 degrees to 88 degrees under mining load (with a slight increase in gpu fan speeds). This was my target temp so I'm happy  

Update 2: Now down to 84-86 degrees at long term load with a lower ambient temperature, this is with 66-71% fan speed. I've been able to bump up the memory to 1800mhz for an extra 2 mh/s with minimal change in temps, so 52mh/s is my new hashrate. Don't feel the need to push it any further for the moment

Hi, im wondering what is the max memory frequency you guys managed to get with a 5700 xt?
Im mining with flashed bios 1445 core 1920 memory. It seems memory clock is maxed out and i manage to get 58.7 Mhs in teamred

I have mine slightly overclocked to 1804 which gives me around 52m/hs with peak 88 degree memory temps. This is on a gigabyte rx5700xt OC (3 fan version). Above that and it gets up to 90 degrees which is too hot for me
