Hashrate RX 470

[deadsix]

To start tweaking the card with watttool i just put the card in system and then run the program in windows, nothing else?
Or is there some other steps like, i need to flash vbios first?
I would appreciate a little step-by-step tutorial just to be sure Wink
I just haven't done this before, only tweaked in msi afterburner which doesnt let you tweak that much. voltage control locked etc.

For wattool there is no problem. You dont need to flash anything.
But to change the memory straps(and get higher hashrate) you need to save the cards bios with atiflash, open the rom file with polaris bios editor. And change the straps. Save the bios file(save as new file, keep the original you saved at first) and then flash with atiflash, reboot.
Which card you have exactly?

600W Bronze running 4 cards? I can only run 3 cards. The system will boot on the 4th but when heavy hashing then the PC will hang. 750W Gold with 5 cards? Interesting...

Probably better configuration for the cards. And maybe slight difference in PSU. And also maybe not dual mining but eth only.

Yes, ETH only. I gave up on dual mining with SIA dropping in value a lot over the past month, and my risers heating up.
Each card is at 1050/1870 - 870/870 with 1500 strap, and the 4 card system draws ~475W from the wall so the 600W Bronze works just fine.

That is quite efficient. It seems that the Ethereum mining might be replaced by the ZCash mining soon.

AriesIV10 , Please tell me, did you do something with BIOS on your card, or they work in defaul mode?

I have MSI RX 470 Gaming X GPUs on this RIG.  Here are the Stats on each gpu:

RIG001 MSI RX 470 gpu01 80.5% Hynix
RIG001 MSI RX 470 gpu02 79.8% Hynix
RIG001 MSI RX 470 gpu03 73.1% Hynix
RIG001 MSI RX 470 gpu04 65.0% Hynix
RIG001 MSI RX 470 gpu05 64.9% Hynix
RIG001 MSI RX 470 gpu06 73.7% Hynix

Here is what I did.

1) Strapped:  Took the 1500 and copied to the three settings larger than 1500.  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 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.

So I dove into Hex editing for the BIOS and its not as complicated as its made out to be. For the layman, I still feel what watttool offers is pleanty. With HEX what you can additionally do is create intermediate memory timing straps and can include an offset in the bios to reduce core volts consumption.
With all the tweking I could do, the BEST I can get my RX 470's is to hash at 25.6 Mh/s while consuming 90W from the wall (GPUZ is like 54W), with a 5 card system at 510W with a lot of bios editing in hex (not polaris). This was a part of my pet 250Mh/s with 1KW at the wall single frame rig/project that I finally achieved yesterday. Its got two 5 card systems in one compact open frame. I will be setting up my 4th such rig to touch 1Gh/s soon.
I have a power ceiling at my place that limits how many rigs I can have running, so most of my research and efforts have been focused into efficiency and not peak performance. Also, the cards run cool, have 0 memory errors, are significantly undervolted and most importantly the risers run cool so i'm insuring a good long run for my hardware.

I think we all know by now that these cards can be pushed pretty hard. But unless you have a proper cooling setup with ducts and air conditioners, and unless you are sure that you are going to dump these cards when ETH goes POS, I would not recommend pushing them to the edge. Find a suitable balance and stick to it, even for perf enthusiasts 27 Mh/s is what you should be happy at with a RX 470 4GB running 24/7. I've made my peace with less.

Just use the Polaris Editor and copy the memory strap from the lower frequency to higher frequency range.

For anybody who still mines ETH with their 470 4GB, do you find that as a new Epoch DAG is released some GPUs are getting incorrect shares and you need to downclock the memory to 1950?

Few months ago all my GPUs worked at 1120/2000 @ 28.5MH/s but now most need to run at 1950MHz for the memory or there are nothing but huge incorrect shares and memory errors.

Let me know if you have more questions.  

what about hardware errors? You dont care about them? I am sure you have cards which produces tons of errors and crash at some point. With 1 card producing errors for me, whole system crashes at some point after few hours or a day. When no errors, no restart for days.

Let me know if you have more questions.  

Is there any way to not have to run wattTool every time? I see you can hand adjust the voltage for each phase - is there any way to set that in the rom automatically using some tool? (Polaris Bios Editor won't do it across all phases)

[PanneKopp]

I actually run a mixed (RX-470/480) Z170 based Rig,
with better no (!) mods,
2 keep it simple switching from ZEC, ETH, XMR, ...
whatever gives me the most in BTC
for my 24 EUR/ct per KW/h.

I understand that it took a lot of your effort and mod is private/custom. But - andy chance to get it publically?

UPDATE: To answer my own question here.  The latest Crimson drivers 16.12 has turn back on the signature checking.  So stick with 16.9-16.11.  Secondly it appears that over time the amount of overclock on the memory on my RX470 Sapphire 8gb cards has slowed down.  This is causing the system to flat not boot.  I had to experiment with slower and slower memory timings to get it working again.  So still a mild overclock on the memory, but a big decrease from what it was using and working well with.  So my ROM's suddenly were not working.  Retuned a ROM and have it working for the time being.  Have to keep an eye on it to see if I need to tweak it some more.

So if you suddenly start having weird behavior you may need to take another look at your ROM's.  I still have another rig happily running on that old ROM.  So something to do with the cards not able to handle the same speeds as before.
------------------------------------------------------------------------------------------------------------------------
HELP!  I need someone to sanity check me here.  I have a rig that I decided to throw a couple more GPU's in it.  I has been running with a custom rom this entire time.  I built this back last summer.  

I thought I had documented all the steps to do the flash, the drivers etc, but apparently I was wrong.  After adding the 2 new cards and flashing them to the same rom as the others one by one.  I assumed since nothing else had changed it would come right back up after the reboot.  

Well it turned out there was going to be a battle getting all the boards recognized and the system to boot.  Finally get it to post and all the boards to be seen by the OS, but all of the devices show the exclamation mark next to them and won't load.  Spent several hours messing with it.  Upgraded the drivers to the latest from AMD.  Still no dice.  

So out of frustration I put the stock roms back on the boards and finally after some mucking around for a while I got the system back up on stock roms and hashing away.  

So I try again this morning to flash the boards to a known good custom rom and I am back into the same mess with exclamation marks next to all the cards in device manager.  So here are my steps.  Please tell me what I am missing.  Is there a newer atikmdag.sys file that I should be using?  I am using one from August.

1) remove all cards but 1
2) boot into windows
3) flash card with desired rom, load up atiwinflash with admin
4) Click load and select new BIOS  > click program
5) wait...screen will hang for about 30-40 secs
6) on confirmation box close
7) in device manager right click GPU and uninstall
reboot
9) card should be redetect but now you are in vga mode as it will fail to load driver.
10) hit windows button and power then holding shift click restart, select troubleshoot, adv, restart options, click restart
11) hit 4 on option screen
12) now in safe mode replace the ati file you need into c:\windows\system32\drivers\atikmdag.sys (overwrite).
13) Use the dseo13b.exe to sign the atikmdag.sys file.
14) bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
15) hit windows button and power then holding shift click restart, select troubleshoot, adv, restart options, click restart
16) select option 7
17) you should now boot up with mod driver and mod bios all working...if not you did some thing wrong. go back to step 9

Hey everyone! I'm new in the whole cryptocurrency thing, started this week in the whole "mining" stuff (ethereum). I recycled some old parts (mobo, cpu, ram, ssd) and bought 2 Sapphire RX470 4Gb Reference (and a EVGA 700B psu)... From the box both 470's started mining at 22.5 Mh/s (Claymore 4.7, only eth), one has hynix memory and the other has elpida. I followed the normal procedure to "strap" the timings (copying 1500 timing) and now the hynix 470 is mining at 27.5 Mh/s (not bad IMO) and the elpida is stuck at 24.5 Mh, not bad either (after moderate OC with Trixx: 1100 GPU, 1925 mem, 63ºC and 73% fan speed).

My question: Do you think it is worth the risk to mod the elpida 470? I'm not so sure about the whole "hex and checksum" process and I've read about a lot of people crying over their dead gpu's... what should I do?

Hmm well you should try if that really interests you !  People have been changing the bios in GPU's since way before crypto mining was a thing.  But for an easier way, check out my website, http://www.cryptominingtalk.com/flashing-bios/ , there is a link for the sapphire nitro 470 (with elpida) to a rom file with the 1500 mem straps.  I get about 26.5-27 with it, without really overclocking the memory too much.

Actually the elpida memory performs better than the Heriox one, i have a few sapphire nitro+ 4gb elpida running at >29Mhash
Here is the ROM: https://bitcointalk.org/index.php?topic=1710085.0
DO NOT FLASH IT, it will not work for reference cards, but i think that u can take timings from there
