Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

If anyone can give some information on how to undervolt I would be very grateful.

You need to play with
cclock
mclock
cvddc
mvddc

I would tell u exact numbers but i don't have 470's to help u out

Think also about the efficiency of your PSU cause it wont deliver 600W which depends on its standard (platinum/gold/silver or even lower) or lets say it consumes wattage by itself and this is sometimes not less.

AND another point... it reaches its highest efficiency on ~50% workload.

[golden0707]

Talking about PSUs . Lets take 1Kwatt PSU with 80 plus gold efficiency.

Does that mean it can output 1kwatt maximum load to peripherals ?  I think sertainly its not good to run it on maximum load, but, in that case I will see something like 1200watt on my kill-a-watt meter at he wall,right ?

And also if I see 1kwatt on my kill-a-watt meter at the wall, that mean that PSU actual load is 1000*0.8=800 watt , and PSU is working in best load condition ?

Here is what I do to get 28MHs+ on my MSI RX470 gaming X 4gb Hynix .  (Find out what type of chip you have in the GPU - You do different processes for each)

1) In ATIwinflash save your base bios:  Open atiwinflash and hit save.  Save the file. 

2) Strapping:  Open Polaris Bios Editor and on the timing (MHz) copy the 1500 data to the three settings larger than 1500. On Samsung you will copy the 1750 timing to the larger values.  Watch this video that shows you how to strap.  I did the same method:  https://youtu.be/OP_zSP2H6ho  This will get you 23.5mhs per gpu.

2) On the MSI Afterburner I set the Memory Clock to 2000 and the Core Clock to 1150(up to about 1275) and press the check(Apply).  This should get you the 28mhs.

3) Now I go to WattTool and look at the numbers for each gpu individually.  In this case for gpu "0:Radeon (TM) RX 470 Graphics" look at the mV number in "R7" = 1150mV.  I do not want this number less than 1000mV.  This is just my preference.  Look at the Voltage Offset.  Whatever number you put in here it will be multiplied x 6.25 so, 20 x 6.25 = 125.  1150 - 125 = 1025mV(which is above 1000)  so this one would be -20 and then click "Set"  This gpu should now produce much lower watts.

4) Go to the next gpu and evaluate the number and make the changes in the Voltage Offset based upon the mV number in "R7."  Each gpu will be different.

Good Luck

Let me know if you have more questions.

Can I undervolt without messing around with the polaris bios editor?

I am happy with the speed, just want to undervolt.

Thanks for the information, I will give it a go.

Hey guys, hey snakey!

I have a little issue with my 4 x rx480 GPUs. Under windows10 i am using CLM's 12.4. It was working fine till today. I just noticed that yesterday I had around 300s/h but right now I have only around 230s/h. No idea why, becouse nothing happened, no config change, neither reboot.

Have you ever had something similar? Any idea how to fix it?
Thank you forward and have a great day!

Is it normal for the wattage to slowly increase the longer you run the miners. And is it normal for the wattage to go up and down in a range and not a constant rate. This happens on all algos but for ZEC it will start around 540 watts go between say 580 and 540 then range will slowly will go over 600 watts. My PSU is 600w EVGA bronze which  I is why I'm concerned. Is this normal or is there something wrong. Also is 550 to 600 watts normal for 3 470's, seems high.

i heard the 470s run at around 90 watts each. What CPU do you have? take one card out and measure again. The difference is what the card is using. High end CPUs may run at over 200 watts

The CPU is amd fx 6200, it is rated as 125w.  I was figuring 100 for each GPU and 125 for CPU should be 425 but it runs close to 600.

Your system without cards draw up to 180-200watt with this CPU, add 140 watt per card, total 180+420 , its 600. All is correct. You can undervolt cards to get 110-120 watt power draw per card.
My rig 6*470s runs at 850watts

I have a 1000w psu 6 x 470 8gb, was running fine before with older claymore version but now I have to unplug 1 card for it to stay on...I think its the watts, 140watts x 6 = 840 + 200w for the rest of the parts....

Don't know how to under vault, have not really looked into it.

You can use the MSI afterburner to undervolt.

[snakey]

hawer183, I have never had that happen to me.

Try go through your setup all over again and make sure no software is getting in the way of your miner.

Maybe someone else can help you out with this one because I am not 100% sure, sorry.

Yes, just start at step 3

Anybody tried the Biostar TB250 mobo?

I was thinking of trying it out but thought maybe you guys already had and have any advise

Thanks...

Have absolutely same question. Some RXs are shipping towards me and expect them next week. Does anybody tried this mobo with 5/6 gpus on?

yes, efficiency is higher at lower temps and system will draw more power as heat builds

[ivomm]

My Sapphire 280x toxic cards continue to hang almost every hour or two. I tried every possible settings for power, clocks, intensity, VM set to 24 GB and nothing works. Most of the cases -wd 1 or -r 0 options manage to restart the miner but sometimes the zecminer window is frozen, I can't even manually or with killing with the task manager close it. Is there a script that can recognize when a zecminer window is not responding and then restarting the windows? I know that -r 1 can restart but I don't want to do it so often. It will waste too much time since in 4 out of 5 cases -r 0 does the job.

It is locked by default , but in options menu it can be unlocked

Anyone have any idea what's the best driver for rx480 for windows? I have a problem with all ReLive drives with my custom bios(signature check re-enabled) and the 16.12.2 also don't work with custom bios, only with 16.11.5. Any difference between them? Or suggest me another bios for stability. Thanx

Hi try using drivers between version 16.08 - 16.10 i currently have 2 rigs with moded bios and both drivers they work like a charm

I use 16.12.1 with my 480s and followed this link to disable that sig-check: https://www.techpowerup.com/228536/amd-bios-signature-check-re-enabled-with-relive-locks-out-polaris-bios-modders

Of course this does require Windows 10 64 bit for it to work..
