Topic: Hashrate RX 470 - page 26. (Read 135025 times)

So what is the general consensus for the new Rx cards?
More efficient to buy 470 or 480? As i see 470 doesn't do that much worse than 480, but it has lower power consumption and is cheaper?
And as a newbie i still havent figured out how this bios flashing goes, when i want to get better results, as i understand its not possible in windows?

This is because there is no reference specified by AMD for 470s - you may have different memory and then it may not work.

What kind of customization you have to do to have same hashrate ?

yeah.. imagine giving that memory "directly" some extra mV's.. mmmm

Haha, i knew this was coming :p

But it's not "completely" true.

For example: The Asus Strix ones they have (As a reference from The Stilt himself) MVDDC control, so basically adding the MVDDC/VDDCI-AUX global offset works perfectly on those

:p

Or a global one 

@Wolf0
great Work have you found VCDDI in the ROM?

lg

Wolf0 what do you get with 470 4gb cards?

What are ur parameters ?

First of all: Awesome Job !

Which card is this ?

28MH @80 watts at the wall per card I can get these suckers to go up to 29-30mh but this is rock solid stable and sips on power...run super cool at mid 50's with low fans. Took alot of bios modding but finally these Polaris dies are living up to expectations.

Hi guys, I am trying 4 days already to make my Asus rx470 rig working.
Rig configuration is following:
Intel G1840,
Asrock H81 Btc Pro,
6 x Asus Strix rx470,
LC Power 1200 V.2.4 Platinum,
8gb ddr3 HyperX 1866,
PCIe extenders with molex.

I succeed to make single card to hash between 25-26mhs, but whole rig (6 cards) is totaly unstable with any configuration I tried. I used Polaris Bios editor to change bios,I copied values from 1425,1500, 1625 strings to columns above. But cards not working stable. I tried different drivers,OS is win 10 Professional, 64 bit, Dual miner - Claymore. For changing memory and gpu core settings i used WattTool, tried with some suggested settings for different rx470 models with Hynix memory from this thread, but without success.
If someone made Asus Rx470 rig working good, please left configuration here or send it to PM.

Thanks in advance.

I've done it - I have a tool to do it inside linux *at runtime.*

I had the same issue... uninstall all the graphic card driver reinstall and it should work.

Not detecting issue are usually due to insufficient power supply either to the cards or the boards are not providing enough.

With hdmi connected to monitor everything works.  I was able to use gpu tweak II and/or msi afterburn to adjust clock settings and I was able to get near 22 eth only with even less watts.  When I unplug the hdmi I have no idea what the settings are being used, have to assume stock, but I can live with the 20.7.  Without being conntected to monitor Gpu tweak won't recognize the card, but windows 7 list it as asus rx 470.  Afterburn recognizes the card, shows 0 data and if it you fill in the settings it, goes right back to 0.  GPU-z at least lets me know fan is working and how much power is being used.  I'ts running, but I'd rather be able to run it harder, but not until I can monitor temps. I think I'm going to order a hdmi emulator if no one here has a better solution to try.

I have this card in my magic interweb box as why I don't leave hdmi plugged in, I had an open 16x pci slot and retired the last of my rockminers, at the halving thus freeing up power to use.  I have not tried modifying bios yet, but I plan to after I educate myself on that task.  

In claymores latest release it does mention in the read me file under faq section:
"- Why miner does not show temperatures for RX 480 cards?
  They use newer overdrive API which is not yet published by AMD."
I assume it applies to the 470's as well, but when hdmi was connected in claymores 6.4 displayed both temp and fan speed.

thanks for your sugestion, but im very disapointed with R9 390, now i sell it with lose arround 15% , next plan to buying 3x Rx470 4gb because some of my friend recomended it.

Can you share this ROM? Plz.
My ASUS 4G RX470 can only run 21M@1140core/7504 

Just keep your 390 and undervolt it.

Thanks man will look that

hi man, which tool do you use?
