Topic: Hashrate RX 470 - page 13. (Read 135060 times)

link to sony's elpida nitro 470 4gb is all down.

can someone please share it here ?

much TIA.

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.

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.  

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

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.

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?


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

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...

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.

750W Gold running 5 cards
600W Bronze running 4 cards

Here are some info correlate PSU and GPU. Based on rx470

550w Bronze - 2 GPU
650w Bronze - 3 GPU
650w Gold - 4 GPU
850w Gold - 5 GPU
1000w Gold - 6 GPU

anyone else have other setup able to achieve more? these are my current setup.

Hehe I never miss a chance


Umm, im not sure, the 95W that you see in GPUZ or some other SW monitor is just the PCIe consumption. Add another 45W atleast that the card would consume through the 6 pin power plug.
So the 67W listed above is more like 67+40=112W. Yours would be around 135W. What h331m4n quoted looks like the actual power draw at the wall at 115W, which includes GPU 6 pin power draw, and PSU inefficiencies. No worries though, some simple settings tweaks using even the bundled Wattman would get you under 120W per card.

Yeah I had no choice but to install Windows 10. Pain in the ass really since the CPU is a Sempron 145. Would of done Ubuntu but since there is no Wattman/Watttol would have to flash to undervolt.

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

So finally my setup is better than someone's else one . Currently, I'm at 28,6 MH/s for 95W. Did you only played with the mV or did you changed something else ? I'll try to reduce again my consumption by removing a few mV.

mV are millivolts, 1V = 1000mV.

Honestly the worst thing that can happen if you go too low is your card won't boot, hence why I only buy cards with dual bios. Leaves a lot more room to play around

My 4x RX470 8Gb (Sapphire) rig hashes at 114Mh/s (28.5-6/per card), 530W at the wall. Each card is around 115-120W. I've done it the proper way though by setting a mV offset directly in the bios using a hex editor rather than playing around with polaris. It's been ultra stable for 2 weeks.

The voltage is the thing that is counted in mV, right ? I've not yet touched to this parameter, by fear of doing some big mistake.

Rubbing salt on wound??

Maybe you can reduce the voltage further to save some more power consumption. Some people do that.

I think the reason why you are hashing so well over is because you have Hynix memory ! Mine, non Hynix (Elpida, right ?), are hashing at 28,6 MH/s for 95W.
