Anyone please want to help me with this ? As far as I can see , I dont see an error. No usual OpenCL call error exit... I can't see the error but the miner reboots !
I have 3 rx480s, Win 10, Crimson 16.9.3 and as you can see , for first few lines it has been working at 30.6MH each. then something has happened and the miner crashes. Can someone please help?

@Claymore, few questions:
1) -cclock: you wrote "you can overclock only", but it seems not to be true for, at least, Windows and Polaris. My 470x can be underclocked (GPU set to 1150 for all states).
2) Any chance to support -cclock and -mclock on Linux for amdgpu-pro drivers (for Polaris)? It is not said "unsupported on Linux", but does not work for me (mem can't be set to 1950 using this).
3) Any chance to support -cvddc and -mvddc on Linux for amdgpu-pro drivers?
4) Are older cards like 7950/7970 supported using amdgpu-pro drivers on Linux?
5) There is an issue on Windows when used -*clock commands: they are applied at some init stage, but for my 470x it instantly changes hashrates only for the card with monitor connected. I can stop and resume other cards for changes to take effect (and show correct/new hashrate), but probably makes sense to fix it somehow, so miner shows correct hashrates after applying values. Of course, if you run it for 2+ time, drivers keep settings and there is no that effect. Still, it is surprising when you run minr with some value and it is not reflected in hashrates.

1. AMD disabled underclocking in theri drivers in past. May be it enabled it again in recent drivers, I did not check it.
2. Linux requires root access for it, I remember someone said that even sudo is not working.
3. Did not check if it is possible.
4. I did not check it.
5. So if I take two 4xx cards, start miner with -*clock option and it will change clocks only for one card?
5. No. In short: changing memory clock using any tool does not change displayed hashrate until miner restarted or card stopped/resumed. Except a card with monitor connected: for it new hashrate is shown instantly.
When I change memory freq using any tool (WattTool) for a single card while miner is running, it instantly changes displayed hashrate only if the card has connected monitor (tested on Rx470). For headless cards the hashrate shown is not changed until miner restarted or card stopped/resumed. That seems to be a feature (@All: please confirm, but I saw someone complained for the same issue).
When you change freq using miner cmdline, and previous freq was not the same, miner sets freq but shows hashrate for old freq until restarted.
5. Some cards I have, wattman doesn't allow changing clocks/voltages unless I pause miner. I didn't think of if monitor was connected. I have some display emulators I got for $15 that helps with VNC, but not sure it would be worth it for more than that...
It is very strange for me because sometimes displayed hashrate changing when I change ram frequency,
sometimes it doesn't react sometimes it react for gpu frequency though
So, I have been using CDM 7.2 for about 5 days now on my W7 system. I was finally able to reduce my wattage pull through Wattman setting (and disabling dual mining), but am still stuck on a paltry 20.75 Mh/s on ETH per each of my MSI RX 470's. I have tried everything on the CDM side, such as setting ETH intensity to the max of 16 in my command line, adding in all 5 of the recommended setx lines, set my virtual memory to 24GB, etc. None of this moved the needle at all.
So, I am now trying the overclocking route before getting into modding the bios on these. A few things are perplexing though. In my Wattman, each of the 4 GPU's can only be increased from 1650 default to 1700. These seems like a very low limit to me and setting all 4 to 1700 had zero impact.
So, using Afterburner, it actually gave me the option to raise Memory Clock all the way to 2100. I only tried 1850 and applied to all 4 GPUs but yet again, absolutely NO impact... all 4 still mining at exactly 20.75. So, my question is, am I doing something wrong? Shouldn't raising the the clock speed on these yield at least a 5-10% bump in mining hash-rate? Or am I completely off base here?
I know of many people using these cards that have achieved 23+ right out of the box, so still trying to figure out why I cannot get close to that mark.

I have same issue with my rx 480 before update drivers I was able only to increase RAM frequency from 2000 to 2100Mhz, after update I can set 2250Mhz in Wattman
Thanks, but I updated to Crimson 16.9.2 over a week ago and it had zero impact. However, I was finally able to at least get a little HR increase by setting to 1700 in Wattman. Unfortunately, this put my wattage usage through the roof! Increased it 50-60W at the wall (although strangely, Afterburner showed steady wattage at around 74 with no increase after moving to 1700 and I can't figure out why). And, this was for only 1 GPU... doing to all 4 pushed my up to around 750 (from 625 before)... all for a measly increase from 20.75 to 21.45, so clearly not worth the extra power drain. I since reset everything in Wattman, tweaked down the GPU mV settings in states 6 & 7 and I'm back down in the 620 range with each of the 4 470's hashing a pretty pathetic 20.7. Bottom line is that a bunch of others here got 23+ out of the box on these cards... no modding, no OCing, nothing. So, I guess I just got really unlucky with my batch.
I guess a pseudo-silver-lining is that this makes my decision really easy on modding the bios on these. I had previously thought that if I got 23 out of the box and could OC 1-2 more, then I wouldn't risk modding. But now, it's a no-brainer since there is no way I'm going to ever be happy running this rig getting less than 21 per card, nor will it likely ever be profitable that way. So, hopefully after modding I can at least get in the 25-26 range. If not, then I don't see much point in adding a 5th card to this rig. My next rig though will not be built with MSI cards, that's for sure!
Edit, I see you have MSI 470s.... well, that's unfortunate. I didn't buy any of them, even early on and supply was hard to find, because their memory is slow (always look at specs on cards... newegg usually has all the details). Nitro 8GB Sapphires on sale right now @ newegg...

It is true that you can't mine with 2 GB ram?
YOU CAN STILL MINE WITH 2GB RAM--
Unless your card is a GTX 750ti. I have 4 AMD R7 265 cards with 2 GB RAM, and they mine Dagger-Hashimoto at 12+ MH/s. The GTX 750ti is crippled by the way it accesses memory, and will only mine at 0.5-1.0 MH/s with Dagger-Hashimoto.
The 750ti would mine scrypt twice as fast as the R7 265 card, and was considered to be in the same tier. My R7 265 cards finally paid for themselves mining Ethereum (ETH). They can mine Expanse (EXP) at almost 15MH/s.
Sometime within a year or so, 2GB cards will not be able to mine ETH, but they will likely be able to mine EXP for some time. EXP is only on Epoch 13. --scryptr

Thank you very much.
I use it for gaming as well, so do you think this is the best?

For Ethereum mining it's more about the memory speed not the processor.
Both of those 8 GB cards you linked have Effective Memory Clock: 8000 MHz. If you look at the specifications for the 4 GB version it only has 7000 MHz memory.
For gaming (which you said you do) you would want the higher core clock rate. So the second one would overall be better. (IMHO) Buy me one and send me one for gaming and I'll let you know
I got the overclocked one.
OCing the memory speed helps ETH more than the GPU speed?
I noticed it helped SIA/LBRY, but not much for ETH.
I got it up to 1360 and stable it seems at 1150 cvddc.
25 ETH 45 LBRY
What should my memory speed, core speed, and cv/mvddc be do you think?
Electric is cheap, and I need the heat any way, so going for as much speed as possible without hurting the card.
Temps are staying around 77c.
I run 1342MHz (stock OC for card) @1030mv. Undervolting will allow card to maintain boost clocks, increasing performance (without setting crazy power limit). Use GPU-Z to check actual core clocks....
Less power means less stress on VRMs, GPU, fans, and possibly PSU. I prefer ~70-73C temps, which I get with ~60% fan, and 80F ambient. Cards all on risers. Night they run like 64C @50% fan (~60F ambient).
Thanks, what rates do you get?
I'm using LBRY, with dcri 40
25ETH 44LBRY in the miner.
Any editing of memory clock and volts?
I'm running 2150 and auto for the volts.
I get ~22MHEth 50MH LBRY with higher DCRI. I do Sia though, 24.3MH, 475MH. Stock 2000MHz memory. Most my cards I run 1260MHz and like 980mv, some down to 960mv (need to lower memory voltage, not sure what this does though).

How do i apply the "-lidag" option correctly ? I want all gpus to use low intensity at the dag part.
I messed around today but did not get it to work.
I am using the 7.1 version of the miner, does that version support lidag ? 7.2 version dont work that good with my RX rigs somehow.
Sometimes some of my rigs freeze at dag creation so i guess this option would be good.

When I change memory freq using any tool (WattTool) for a single card while miner is running, it instantly changes displayed hashrate only if the card has connected monitor (tested on Rx470). For headless cards the hashrate shown is not changed until miner restarted or card stopped/resumed. That seems to be a feature (@All: please confirm, but I saw someone complained for the same issue).
When you change freq using miner cmdline, and previous freq was not the same, miner sets freq but shows hashrate for old freq until restarted.

I was using -cclock for a while - it works good. (in fact it's the fastest way to identify cards if you set something like 1010, 1020, 1030, etc...)
Watttool would apply values immediately if you uninstall the AMD drivers crap and just point devices to the driver dir.

I got this precise issue when my swap file was too small. Random gpu wasn't compiling dag while others where okay (up to 2 gpu failed depending of swap size)
Looking @ your rig's specs, I misread you had 4 Gb :/
WooHoo! It solved the issue. Win10 original drivers + 16GB paging file = success.Looking @ your rig's specs, I misread you had 4 Gb :/
I really did not expect that it will require manual paging file with 8GB or system RAM since miner process used only ~250MB (as shown by Windows).
Thank you, now it works as it should.
Seems like the os must account some storage capability when dealing with 6 dags, not really using it. Reminds me of old Id Software games, crashing without swapfile but happy with 1 Mb of it (if you had enough ram of course)

@Claymore, few questions:
1) -cclock: you wrote "you can overclock only", but it seems not to be true for, at least, Windows and Polaris. My 470x can be underclocked (GPU set to 1150 for all states).
2) Any chance to support -cclock and -mclock on Linux for amdgpu-pro drivers (for Polaris)? It is not said "unsupported on Linux", but does not work for me (mem can't be set to 1950 using this).
3) Any chance to support -cvddc and -mvddc on Linux for amdgpu-pro drivers?
4) Are older cards like 7950/7970 supported using amdgpu-pro drivers on Linux?
5) There is an issue on Windows when used -*clock commands: they are applied at some init stage, but for my 470x it instantly changes hashrates only for the card with monitor connected. I can stop and resume other cards for changes to take effect (and show correct/new hashrate), but probably makes sense to fix it somehow, so miner shows correct hashrates after applying values. Of course, if you run it for 2+ time, drivers keep settings and there is no that effect. Still, it is surprising when you run minr with some value and it is not reflected in hashrates.

1. AMD disabled underclocking in theri drivers in past. May be it enabled it again in recent drivers, I did not check it.
2. Linux requires root access for it, I remember someone said that even sudo is not working.
3. Did not check if it is possible.
4. I did not check it.
5. So if I take two 4xx cards, start miner with -*clock option and it will change clocks only for one card?
5. No. In short: changing memory clock using any tool does not change displayed hashrate until miner restarted or card stopped/resumed. Except a card with monitor connected: for it new hashrate is shown instantly.

When you change freq using miner cmdline, and previous freq was not the same, miner sets freq but shows hashrate for old freq until restarted.
5. Some cards I have, wattman doesn't allow changing clocks/voltages unless I pause miner. I didn't think of if monitor was connected. I have some display emulators I got for $15 that helps with VNC, but not sure it would be worth it for more than that...
It is very strange for me because sometimes displayed hashrate changing when I change ram frequency,
sometimes it doesn't react sometimes it react for gpu frequency though
So, I have been using CDM 7.2 for about 5 days now on my W7 system. I was finally able to reduce my wattage pull through Wattman setting (and disabling dual mining), but am still stuck on a paltry 20.75 Mh/s on ETH per each of my MSI RX 470's. I have tried everything on the CDM side, such as setting ETH intensity to the max of 16 in my command line, adding in all 5 of the recommended setx lines, set my virtual memory to 24GB, etc. None of this moved the needle at all.
So, I am now trying the overclocking route before getting into modding the bios on these. A few things are perplexing though. In my Wattman, each of the 4 GPU's can only be increased from 1650 default to 1700. These seems like a very low limit to me and setting all 4 to 1700 had zero impact.
So, using Afterburner, it actually gave me the option to raise Memory Clock all the way to 2100. I only tried 1850 and applied to all 4 GPUs but yet again, absolutely NO impact... all 4 still mining at exactly 20.75. So, my question is, am I doing something wrong? Shouldn't raising the the clock speed on these yield at least a 5-10% bump in mining hash-rate? Or am I completely off base here?
I know of many people using these cards that have achieved 23+ right out of the box, so still trying to figure out why I cannot get close to that mark.

'-mode 1' works fine but I've found a bug when setting the '-mode' for a single GPU when a '-dcoin' is set (I have version 7.2):
'-mode' works with these commands: '-dcoin dcr -mode 1-0' or '-mode 1-0'
'-mode' is ignored with this command: '-dcoin lbc -mode 1-0'
'-mode' works with these commands: '-dcoin dcr -mode 1-0' or '-mode 1-0'
'-mode' is ignored with this command: '-dcoin lbc -mode 1-0'
Confirmed, it will be fixed in next update.
That's great, thanks for the quick response. Can I just say that your miner is amazing BTW, 33 mh/s on an AMD 290!

I sometimes get a hang if the driver crash on one of the cards in the rig. How can I restart the miner f.ex every 3 hours? or more? Did you make a restart parameter?
"-r" sets restart time. "-r 180" equals restart every 3 hours
If, you are using Nvidia cards, disabling "HDMI drivers" in Device Manager for each GPU really helps with driver crashes not leading to whole PC crashes.
Hope, that is helpful.
