Topic: Hashrate RX 470 (Read 135065 times)

You can't edit it at all - any change does nothing.

Boysie - he's an idiot.

Try 8GB timings, they usually work.

Simple - well, first, I use far better timings than Ubermix... if you're using Ubermix, no wonder you can't stably clock above 2000.

If you're on Linux, your mod you did yourself almost certainly did not undervolt shit.

I'll PM you for the ROM, and I'll work on it - one min.

I tested them with 1000mv on core and mem voltage so I don't think that could be the problem.

Did u check if they are power gated at bios? Easiest way is to go + on voltage and raise memory accordingly.

Can anyone help me get higher hash rates?

I bought used Sapphire RX470 4GB mining edition cards and I don't have the original bios to mod it. With current bios and others that I have tried, the cards give cca 26Mh/s @ 1150/1850.

If I raise the mem clock above 1850 I get errors instantly. No matter the BIOS.

The cards have Samsung memory. I'm using win 10. Cards are overclocked with claymore miner.

In linux you need ohgodatool or something similar do play around with voltages, etc.  I think ethos has something like that built in.  Use windows unless you have a huge deployment to do.  You can also check out GatelessGateSharp, it modifies the memory timings live without modifying the bios. 

Setting the core voltage to 900mv in smOS (linux) does nothing. It doesn't work in linux. You can do it like that in windows and it will work, but to get the power consumption down and the undervolt to work, you have to have the undervolt bios modded into the gpu.. you can get down to 800-900w maybe even less if you undervolt with the bios and mine eth only

And yea if you edit the memory strap timings in the bios you can get increase in hashrate as well as decrease in power consumption.. You can likely get 28.5-30mh/s

Claymore 11.6, blockchain driver. ASUS RX 470 mining edition hynix got 30.2 MH/s 1169/2050, the same elpida GPU got 29.7 MH/s 1169/2000 (and necessarily powlim 50).

I Have a Asus Strix 470 4gb Hynix and with Claymore v11 and PhoenixMiner i get 28.2 MH/s on ETH. Standard timings from 1:1500 to 1:2000 and -68 +20 1150 1960.

I have Sapphire Rx 470 4gb Mining Ed. I get a hash rate of 860. I am mining Graft at the moment. Especially Sapphire Mining Edition cards have a very good hash rate.

Also Rx 480 Ref Gpu. Those that come with Dell ready systems also give a very good hash rate.

Hi guys!

I am new in this and until now I have read all the different discussions regarding these may kind of GPUs RX 470.
I have also just bought my first rig: 6pcs of XFX RX 470 8 Gb (Hynix) - RX-470P85BDB - link with all details here: http://hardware4mining.com/?product=xfx-amd-radeon-rx-470-8gb-gddr5-hynix

The rig is already configured to run SMOS, pool solo mining for ETH.
I have begun this with some money borrow from my friends that I will need to return each month - hope to manage this

So, after almost a month of testing different ways of OC them to be more stable (only from SMOS OC mode - they do not have Bios mode changed), I have the following feedback and questions:

*Feedback:
- The cards seem to work more stable as following: core 1105 and mem 2105, core undervolting at 900 with stage 4 (from SMOS OC Control Panel)101
- They are running all between 27,70 - 27,77 Mh/s at 53°C - 61°C, meaning a total of approximately 166,5 Mh/s. I have also used core 1150 and mem 2150 (total 171 Mh/s) but seems to work more unstable from the pool chart.

* Questions:
- How can I reduce the actual consumption of all of the rig? I have a consumption indicator at the rig alimentation that shows 1050W.
- Is there a possibility to still improve the hashrate without modding the Bios? Being stable at the same time (if somebody has already the experience)
- If modding the Bios, this will allow me to gain both hashrate and reduce power consumption at the same time?

Any other recommendations if someone has the same type of GPUs XFX RX 470 8 Gb (Hynix) - RX-470P85BDB? I will greatly appreciate.

My best regards!

Hi,
I modded my ASUS-RX-470-DC2 4 GB Elpida memory.

ETH: ~28,6 Mh/s,  @1050 CoreClk, @2000 MemClk
XMR: ~774 h/s,     @1050 CoreClk, @2000 MemClk
with 1100 MHz CoreClk the ETH speed is ~29Mh/s, but the power consumption will increase from 110W to 122W.

Hi sir
You have ROM basic memory hynix Rx 470 sapphire 4gb nitro oc??
Please share it here
Very thanks

The AMD mining cards? BBT did a live stream on those.
