If you turn one thing up, you have to turn something else down, so the power stays the same.
Memory frequency is the biggest positive hammer for hash rate, and voltage is the biggest way to reduce power.
Up the memory speed by 100 MHz, and reduce the voltage from 1000mV down to 950. And then you can down clock the core frequency, too.
You need to keep it all balanced

Phil,
The guy from Amazon just sent me a replacement board to test even I didn't ask for it. (I said I might have an issue with his MOBO but to wait a few more days for me to test and play with it.
and he sent 6 free risers ... that guy is EPIC ! (USB)

If you are referring to WattMan, it's built into the AMD driver: Gaming -> Global Settings -> Global WattMan.
can't find that, in fact i never been able to start Amd Settings (Tell me i need to plug a card)
Reinstalled, all good thanks
I tried your settings, works great on 3 cards. My PowerColor take it too but doesn't boost it much like 1 MH since the ASIC quality seems to be killing anykind of improvement on that card.
The last one running 27.x MH but drop to 15-18 and back to 27. Needs some tweaking.
Rigs was up for 7.5 hours last night ... crashed when I arrived at job. Had to reboot a few times some card didn't start to hash.
Now PC seems to be crashed

Flashed my card with the bootstrap mod.
I got a PowerColor with an Asic of 69.1% and the mod didn't do jack shit. It's the one throwing invalid share also. I think i have a bad card. good thing is I have two 80ties and my best is 89.x% two 70X also (75-79)
The 5 others are running good.
Now can anyone share me WattTool ? I'm unable to download it from the overclock site ... even if I created an account. Getting an error from the forum
Thanks.

Still trying to figure out why I can't get better than 20.7 hash-rate no matter what I do, but one thing at a time
If you want to see high hash rates (27-28mh) you MUST mod the bios.. there's a ton of info on it:

Ah oh thanks... I just had a bit of success lower wattage use before I saw your post... I did stop Claymore while I messed with Wattman this time, which I think helped. I made the same kinds of changes as before that crashed the system but this time it was fine. The slight difference is that instead of using the slider bare to lower the entire curve, i manually over-wrote only state 6 & 7 with lower values than default (I also re-set wattman on every card before doing anything. I did not use the same values for each card because some were over 1100 in state 7 while others will right around 1000. Still, after lower these values a bit for each GPU, I checked my Kilowatt and found that wattage dropped from 695 to 625, so that's definitely a mover in the right direction! And, this change had NO effect on hash-rate, so I would bet that I can fine-tune a bit more and get to around the 600 mark, which would already be 25% lower than what I was at with dual mining yesterday.

Big shout out to Phil for sending me the extra molex cable I needed to get my 4th 470 up and running! Thanks also for the extra goodies you included Phil... really appreciate it!
So, as it stands now, I am getting just shy of 82 Mh/s on ETH and about 1300 Mh/s on DCR. I am happy to finally have this rig running with 4 GPU's but I am still baffled at how these MSI 470's are only getting 20.7 per unit on ETH. I have tried pretty much everything suggested in this forum and in the Claymore readme file but nothing notably effects the speed of ETH mining. I've done the following:
- Added the 5 setx lines to my .bat file
- Added the "-ethi xx" command within the command line of the .bat file. Tried it at 10, 12, 14 & 16.
- Added the "-ethi xx" command to the config file. Tried it at 10, 12, 14 & 16 in various places.
- Increased my Virtual Memory from 16GB to 24GB
None of these moved the needle on ETH mining at all... still all 4 GPU's averaging 20.7 per unit. The only thing that effected ETH speed at all, was to ratchet down DCR intensity significantly but the minimal gain of .4% (from 20.72 to 20.82) would actually be more than offset by the dramatic decrease in DCR effectiveness. On the flip-side, bumping up DCR to 35 increased its hash-rate by ~15% but only nominally effected ETH mining (less than .1%). Bottom line, nothing I've have tried so far is getting me even remotely in the ballpark of the ~23 Mh/s that others are getting from those GPU's out of the box.
I would almost just think I got a bad batch, but my 4 GPUs came from 2 different vendors (3 from Amazon and 1 from NewEgg), spread over 3 orders over 2-3 weeks, so this seems unlikely. I really wanted to close this gap before proceeding with modding, but it's looking bleak at this point. I am putting off purchasing a 5th GPU for this rig until I can figure out exactly how much I can improve its current performance. Frankly, at less than 21 per card, it's barely going to be profitable, especially at the ridiculous power draw it is currently at... which reminds me...
So, I have my rig plugged into a KilaWatt unit. While running the rig with 3 GPUs, it was pulling around 630-640 watts. This seemed high to me because I was thinking max of 330 for the GPUs +140 for the i7-6800k, which left about 160 watts for the Mobo, SSD, heatsink, etc. Again, seemed a bit high but not out of the realm of possibilities.
Well, here's the perplexing thing... after hooking up the 4th GPU, KilaWatt now says I am using 810 watts! That's a 170 watt bump over the 3 GPU set-up. So, how exactly can a GPU with a max TPD of 110 watts add 170 watts of power usage? At this rate, I couldn't even add another GPU to this rig as my PSU is 1kw. I know I need to really dig into the power settings that have been mentioned here recently but was wondering if anyone could explain how a 110w GPU could add 170w to my power draw.
Thanks again for any tips!

I would push down the core 20%
Up the memory to 1850
That will up the MHs and lower the power without bios mod
120tdp isnt the max power draw.
Also msi cards have a high power set than the other 470s
If you want help with bios mod I will help anyway I can
If you pay 10cents or more in power I wouldn't dual mine. Your only talking about maybe 10-20$ profit
Pushing the cards harder and hotter for only 20$ ehh I'll save them
Yeah, my electricity is 11 cents, so doing rough math for 110 watts, cost me about $9/month. At best with 4 GPU's on DCR, I could mine maybe 15 in a month, so at DCR current rates, maybe $5 profit/month at best so really not worth it. Now, if it goes $2 and above then certainly worth looking at but not really at $1.
I am curious on your 2 suggestions... can these settings be done within the AMD WattMan App? I haven't really dug into that yet but if it is indeed managed there, I will certainly try that ASAP!
Yes those settings are for wattman. It'll be the easiest way to play around with
OK, so I attempted to make the recommended changes this morning but not really seeing any results, so I am probably doing something wrong.
Here is what I tried in Wattman:
- decreased Power Limit (in the Temp section) by 20%
- increased the Memory Frequency from 1650 to 1700 (I know 1850 was recommended but the max value I could set in Wattman was 1700, and only "State 1" was enabled (on all 4 cards) so, only 1 State moved and only up 50 Mhz
I applied this changes on all 4 GPUs. There was NO impact to hash-rate. There was impact to wattage usage but in the wrong direction... went from about 695 to 710. When I moved the Power Limit back to anything between -10% and 0 (flat), I got back down into the 695 range.
After this, I opened Afterburner. Also my first experience with it so still early in the learning curve on all of this stuff.
- Did further testing with Power Limit but same results as with Wattman... no impact between -10% & flat but increased wattage pull with -20%
- In this app, Memory Clock was movable all the way up to around 2000, so I tried the 1850 and applied to all 4 GPUs, but alas, again, zero impact to hash-rate on any of the 4 GPUs.
The other thing I briefly played with (but with scary results) was the GPU frequency in Wattman. I saw a youtube video where they were pulling down the state 6 & 7 frequency max values to around 970 & 1000 respectively. I tried that on GPU#1 (not a large decrease from the reflected values) and it actually lowered my wattage a bit. But, when I did the exact same thing to GPU#2 (this was actually a larger % decrease from the reflected values as this card seems to run hotter & pull more wattage than the others), it ended up stopping that GPU and crashing my system. After that, I didn't mess with the GPU settings again.
So, given all of this, can anyone provide some advice on where I am going wrong? Where exactly should I be trying to lower the power/core settings? And, am I missing something on the Memory increase side?
Thanks again for the help!
20% was on core not power limit.
Memory only has one state. Did surprise me tho it doesn't let you push more
Did you reset wattman before you started using afterburner?
- ok, how do you decrease core by 20%? not sure what that term means in relation to the fields in Wattman or Afterburner
- yeah, me too, but I Afterburner did let me increase memory to the recommended 1850... but still no change in hash-rate
- no, I have not done anything like a reset to wattman either before or after using afterburner, but can give that a try if needed
Also wanted to clarify something... I have been making these changes real-time while the GPUs are mining. Is this OK or do I need to stop Claymore while changing then re-launch every time to see if it had an impact?
I always stopped the miner then edited and restarted claymore
In wattman on the first settings has a bar below all the states it goes left and right. It will lower the core frequency or up it.
What I would do is go into wattman reset each card close wattman then use afterburner till I got where I wanna be

ETHPool saying my Miners are reporting
195.0 MH/s | 86.0 MH/s | 81.0 MH/s
Figured it out ...
I got an insane number of =>
GPU #1 got incorrect share. If you see this warning often, make sure you did not overclock it too much!
/sigh .... bad GPU ? it's not even overclocked
EDIT: quick reboot ... all 6 cards minings impressive and no errors ! I saw that GPU error before but never at that insane pace. I flipped the "GPU 1" on the MB and it's the same "GPU 1" throwing the error. Not sure it's GPU related anymore.

I am not in a good mood today - my entire ETH farm is down due to unknown power trip - spent hours going through what is causing the trip - nothing seems to be amiss but something is causing the main db board to trip.
Never had problems with the farm for many month now, until I started to run a few test rigs to do a comparison selling hash at Nicehash instead of mining ETH directly - that project is put on hold for a while until I find the culprit.
Its going to be long day tomorrow with my electrician.
I have a strange feeling... that I have to get rid of them USB risers

I had the same issue when my 7kw farm was being rented on betarigs a long time ago. The problem was that when the farm got rented, the miners would go idle
for a second while the pool/server changes and then go full power , all of them at once, that resulted in brief peak power usage that was obove the fuse amperage.
I solved it by splitting farm into two smaller farms that i then continued renting out with no problems, because they would never again be rented (and went load->idle->peak) at the same exact time.
Dont know if nicehash works on same principle rule as betarigs did tho, but maybe it helps out. It's easy to just say "get higher amp fuse", but it's better to solve the core issue imho.
cheers

- Added the "-ethi xx" command to the config file. Tried it at 10, 12, 14 & 16 in various places.
- Increased my Virtual Memory from 16GB to 24GB
None of these moved the needle on ETH mining at all... still all 4 GPU's averaging 20.7 per unit. The only thing that effected ETH speed at all, was to ratchet down DCR intensity significantly but the minimal gain of .4% (from 20.72 to 20.82) would actually be more than offset by the dramatic decrease in DCR effectiveness. On the flip-side, bumping up DCR to 35 increased its hash-rate by ~15% but only nominally effected ETH mining (less than .1%). Bottom line, nothing I've have tried so far is getting me even remotely in the ballpark of the ~23 Mh/s that others are getting from those GPU's out of the box.
I would almost just think I got a bad batch, but my 4 GPUs came from 2 different vendors (3 from Amazon and 1 from NewEgg), spread over 3 orders over 2-3 weeks, so this seems unlikely. I really wanted to close this gap before proceeding with modding, but it's looking bleak at this point. I am putting off purchasing a 5th GPU for this rig until I can figure out exactly how much I can improve its current performance. Frankly, at less than 21 per card, it's barely going to be profitable, especially at the ridiculous power draw it is currently at... which reminds me...
So, I have my rig plugged into a KilaWatt unit. While running the rig with 3 GPUs, it was pulling around 630-640 watts. This seemed high to me because I was thinking max of 330 for the GPUs +140 for the i7-6800k, which left about 160 watts for the Mobo, SSD, heatsink, etc. Again, seemed a bit high but not out of the realm of possibilities.
Well, here's the perplexing thing... after hooking up the 4th GPU, KilaWatt now says I am using 810 watts! That's a 170 watt bump over the 3 GPU set-up. So, how exactly can a GPU with a max TPD of 110 watts add 170 watts of power usage? At this rate, I couldn't even add another GPU to this rig as my PSU is 1kw. I know I need to really dig into the power settings that have been mentioned here recently but was wondering if anyone could explain how a 110w GPU could add 170w to my power draw.
Thanks again for any tips!
So, as it stands now, I am getting just shy of 82 Mh/s on ETH and about 1300 Mh/s on DCR. I am happy to finally have this rig running with 4 GPU's but I am still baffled at how these MSI 470's are only getting 20.7 per unit on ETH. I have tried pretty much everything suggested in this forum and in the Claymore readme file but nothing notably effects the speed of ETH mining. I've done the following:

I would push down the core 20%
Up the memory to 1850
That will up the MHs and lower the power without bios mod
120tdp isnt the max power draw.
Also msi cards have a high power set than the other 470s
If you want help with bios mod I will help anyway I can
If you pay 10cents or more in power I wouldn't dual mine. Your only talking about maybe 10-20$ profit
Pushing the cards harder and hotter for only 20$ ehh I'll save them
Yeah, my electricity is 11 cents, so doing rough math for 110 watts, cost me about $9/month. At best with 4 GPU's on DCR, I could mine maybe 15 in a month, so at DCR current rates, maybe $5 profit/month at best so really not worth it. Now, if it goes $2 and above then certainly worth looking at but not really at $1.
I am curious on your 2 suggestions... can these settings be done within the AMD WattMan App? I haven't really dug into that yet but if it is indeed managed there, I will certainly try that ASAP!
Yes those settings are for wattman. It'll be the easiest way to play around with
OK, so I attempted to make the recommended changes this morning but not really seeing any results, so I am probably doing something wrong.
Here is what I tried in Wattman:
- decreased Power Limit (in the Temp section) by 20%
- increased the Memory Frequency from 1650 to 1700 (I know 1850 was recommended but the max value I could set in Wattman was 1700, and only "State 1" was enabled (on all 4 cards) so, only 1 State moved and only up 50 Mhz
I applied this changes on all 4 GPUs. There was NO impact to hash-rate. There was impact to wattage usage but in the wrong direction... went from about 695 to 710. When I moved the Power Limit back to anything between -10% and 0 (flat), I got back down into the 695 range.
After this, I opened Afterburner. Also my first experience with it so still early in the learning curve on all of this stuff.
- Did further testing with Power Limit but same results as with Wattman... no impact between -10% & flat but increased wattage pull with -20%
- In this app, Memory Clock was movable all the way up to around 2000, so I tried the 1850 and applied to all 4 GPUs, but alas, again, zero impact to hash-rate on any of the 4 GPUs.
The other thing I briefly played with (but with scary results) was the GPU frequency in Wattman. I saw a youtube video where they were pulling down the state 6 & 7 frequency max values to around 970 & 1000 respectively. I tried that on GPU#1 (not a large decrease from the reflected values) and it actually lowered my wattage a bit. But, when I did the exact same thing to GPU#2 (this was actually a larger % decrease from the reflected values as this card seems to run hotter & pull more wattage than the others), it ended up stopping that GPU and crashing my system. After that, I didn't mess with the GPU settings again.
So, given all of this, can anyone provide some advice on where I am going wrong? Where exactly should I be trying to lower the power/core settings? And, am I missing something on the Memory increase side?
Thanks again for the help!
20% was on core not power limit.
Memory only has one state. Did surprise me tho it doesn't let you push more
Did you reset wattman before you started using afterburner?

I am not in a good mood today - my entire ETH farm is down due to unknown power trip - spent hours going through what is causing the trip - nothing seems to be amiss but something is causing the main db board to trip.
Never had problems with the farm for many month now, until I started to run a few test rigs to do a comparison selling hash at Nicehash instead of mining ETH directly - that project is put on hold for a while until I find the culprit.
Its going to be long day tomorrow with my electrician.
I have a strange feeling... that I have to get rid of them USB risers

If you have fuses in your electric system ... one might be defective and cause the main to trip. Just saying, i'm no expert

I just bought 8GB of ram.
I will install that tonight and do for further testing.
Phil, the seller is really friendly and helpful. He's even willing to ship to Canada for a replacement if I want (Wasn't shipping to Canada at first). Cool guy.

I don't mind running the 4 cards on the board. At this moment I had to open my den slider and my back door in the garage. The 66 f outside temp is too hot to run with doors shut. My garage is down to 90f running the 19 cards. I am leaving 1 idle card at the moment. I also do not mind that.
I took off from mining today I went to Six flags great adventure with the wife and watch two shows for fright fest. It is nice I am 20 minutes from them and have a season pass. Wife liked it so some points for me.
I offered to take her back to tonight for another show.
I am also going to help put up a wall in the neighbors garage today in a few minutes.
Tomorrow I will go to the solar array finish setting up 1 eth rig
