Hashrate RX 470

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

lg

Of course - there's several places to set it, depending on state.

Or a global one

You know that one doesn't work for VDDCI with RX cards.

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

No shit? I gotta get me some!

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

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.

What are ur parameters ?

Parameters? I can tell that shit is custom - he's not one to use a crappy editor like Polaris BIOS Editor for anything but fixing checksums.

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

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?

[nevermind41]

My advice ''Don't try to lower the power from bios'' Just edit memory straps and gpu frequency. It drops just in monitoring softwares. 470 is the best choice. There is no need to buy 480.

@nevermind41

Which design of the rx 470 8GB is this?

Thanks in advance

Nice speeds but I call BS at 80W per card, probably closer to 95W which is still excellent. The rest of the card adds an easy 35W, especially for non reference cards.

Why are you using positive offset instead of just keeping core voltage higher? Also why not dual mine and why not lower clocks and voltages more for more efficiency?

[nevermind41]

@soundtuner  I have Sapphire Nitro 8 GB
@Truthchanter  I lowered the core voltage and power to decrease the power consumption.Dual mining needs more power consumption and also it effects the ether mining speed. Low power consumption with low gpu speed (but it mustn't effect the ether mining) + high memory speed is best choice

@nevermind41 as i understand i could get a msi 470 8gb  and take wattman to tweak the card's settings ?

[xleejohnx]

Okay I have 4g rx 470s cards I want to bring down the power consumption with hurting the hash.
Changing the core would do that. But values should put? Should I stop the core at 1050/800 or 1050/950
Or should I go about it a different way? Any thoughts ideals or guidance or rom share would be helpful

Right now I modded the bios
Changed timing and upped memory
And wattman I did -15
I'm getting a total 147mhs on 6 cards with 860 at the wall

Basically I'm trying to get away from wattman

If you want to but 8 gb version of 470, I advice you to buy sapphire nitro 8 gb

[S.N.U.F.F.]

Probably a bump to VDDCI + downvolt using global offset, but looking more carefully... the memory controller load on that is rather light. Actually, hella light for that hashrate.

how much is safe to bump VDDCI in polaris editor? My cards(470 asus strix) have 1000 mV in stock. I want to try and increase it to obtain better mem clocks stability.

[S.N.U.F.F.]

Polaris editor doesn't show VDDCI or let you edit it.

I mean those memory mV straps(controller?) in Polaris editor.
Any sense to bump it higher than 1000 mV for better mem stability?

[Eliovp]

Those strix cards have mvddc control which makes them unique and very interesting! :-)

In other words, adding an mvddc offset is possible for these

Yeah, but you gotta put it in yourself. No easy GUI tool there.

Exactly, already done it on the reference and on my nitro's (vddci for these models )

anyone have xfx 470 4gb? what is your max hash rate on eth? anyone with 27Mh?

Yes I do and yes it does

[rabbitr32]

i have a power color red devil rx470 4GB. just follow this guide https://www.youtube.com/watch?v=OP_zSP2H6ho copy the memory timings for the 1500mhz memory speed to the rest above e.g. 1750mhz. max hashrate i got with 1030core/1900mem is 27mh/s pulling about 100watt

been running more than 12Hours zero problem. temp stable around 55c
