Get ready guys

How and where???

Looking forward to see RX470 performance in mining!

boysie

perf stats would be nice...a pic of a box is not really that useful. I'm guessing some one you knew had stock delivered today and now you have some ahead of the launch tomorrow.

someone said 24mhs in another thread (at default clocks?) idk about power consumption, but since they're cheaper than 480s i might look for 470s over 480s

This card can do more than that !

TEMP MAX at 59C

Can't wait to see some hash rates.

adaseb

Yours is 8GB or 4GB?

cscheat

8GB

Hi, everyone!

@cscheat
What's the TDP of your card?

can you post a "proper" scrnshot? Like FUll screen GPU Z etc?

Confirmed mining speed with RX 470

4GB = 20MH
8GB = 25MH

th00ber

@cscheat because of the mem clock speed ?

boysie

@cscheat that's only true if the 4GB card has the slower mem, if you get a 4GB card with the faster mem than it should go the same speed as the 8GB, same happened with the 480s

boysie

there are even some 480's starting to be listed using 8100Mhz mem and these should hash even faster..maybe up to 29?

Truthchanter

@boysie shouldn't the 470 4gb mem be able to OC'd to 8gb speeds and hash at the same speed as the 8gb?

boysie

tbh I'm not sure until I see it, this was true on the 480s 4G but I don't think will be the case for the 6600Mhz mem

The 7000MHz mem though I'm not sure, it looks like the max on these is 2000

I found this review: bit-tech.net/hardware/graphics/2016/08/04/sapphire-radeon-rx-470-nitro-oc-4gb-review/12

he said he had his at 1950

but another that had the old problem of not getting above 1800 from 1750.

I think the wattman bug is lurking around still and causing issue but no idea what the max you can get to until I crack open the boxes sitting next to me in a few hours when I get home from work.

Truthchanter

@boysie nice im awaiting to hear your results

ksukhin

How do people get a hold of these cards? Especially before they're released?

boysie

so the card is in...doing just 1 at a time....

1st issue, installing using the CD results in Wattman only allowing up to 1800 mem from 1750

resolved this by removing and installing the wattman from the 16.7.2 driver set and using the drive directly onto the card.

now wattman allows up to 2100 on this card.

the power defaults to 1000 on mem

setting 2100 and clicking apply results in black screen....so not good...tried 1950 and seemed ok but got a black screen as soon as miner started....

then after reboot...miner crashes as soon as mining starts...reseting gcard...reinstalling and rebooting all have no effect ...miner now always crashed...rebuilding OS

The reason is memory speed. Max is 1800MHZ ....

What were you getting for stock MH/s?

Ouch... but are you saying it only mined successfully (at least temporarily) with 16.7.3? I'm surprised you had to resort to reinstall OS, I would have thought reinstalling the driver or trying a new psu cable may do the trick

Looks like the 1800max is due to 16.7.3 driver, 16.7.2 may work

What were you getting for stock MH/s?

stock was 22.1Mh dual mining....cant get it to run a second time though looks like not compatible with new windows 10 version 1607

trying to work out how I can get to 1511 which is not easy unless you have the iso to make new bootable USB's

cscheat

any solutions??? im using 16.7.3

boysie

cscheat said:

I used C:\AMD\Non-WHQL-64Bit-Radeon-Software-Crimson-16.7.2-Win10-Win8.1-Win7-July9\Packages\Apps\CN\CNext\cnext64\ccc-next64.msi to install the 16.7.2 version of wattman, its not the card drivers causing the issue its wattman.

so remove it all download and extract 16.7.2 ...no need to try and install but it will if you have a 480 attached.

then run C:\AMD\Non-WHQL-64Bit-Radeon-Software-Crimson-16.7.2-Win10-Win8.1-Win7-July9\Packages\Apps\CN\CNext\cnext64\ccc-next64.msi

then use device manager to update the 470 drivers from the CD.

cscheat

why not just use DDU to remove the 16.7.3, then fresh install 16.7.2 ?

cscheat

Boysie, what MH are you getting ?

I mean your 4GB RX 470

lex7

tomorrow I get the Sapphire NITRO OC RX 470 version 8GB what drivers need to install
16.7.3 or 16.7.2 ? I'm confused

boysie

hi all, so the news is not good

Stock is 22.0/1 on this 4GB card (Sapphire NITRO OC RX 470 4GB)

The problem is you can not change from stock settings on MEM clock, nothing works, mem has to stay as is or you simply lose any chance of maintaining even above 20Mh

This is the exact same issue I had with my xFx 480 4GB and it was down to drivers and a crappy wattman app

so leaving these all at 22.1MH dual mining with 330MH SC running around 210w at the wall on a single card and system. using a evga 1200 P2 @230v using 16.7.3

STOCK
2 cards + sys = (dual mining @ 30 DCRI)
435w @ plug
44.4MH/666MH

2cards + sys = 445W (Dual mining @ 45DCRI)
445w @ plug
43.7MH/984MH

3 cards + sys = (dual mining @ 30 DCRI)
620w @ plug
66.6MH/999MH

3 cards + sys = 445W (Dual mining @ 45DCRI)
647w @ plug
65.5MH/1474MH

stock settings

there is light at the end of the tunnel, by using wattman from 16.7.2 you can see you should be able to get the mem up to 2100 although again simply changing the mem to anything other than stock is pointless as it just wipes out the MH


the old setting that used to be the only good option also now works again, where you basically set -20/800 and 1750/800.

NOT STOCK

2 cards + sys = (dual mining @ 30 DCRI)
297w @ plug
44.1MH/661MH

2cards + sys = (Dual mining @ 45DCRI)
310w @ plug
40.5MH/912MH

3 cards + sys = (dual mining @ 30 DCRI)
355w @ plug
66.1MH/991MH

3 cards + sys = (Dual mining @ 45DCRI)
365w @ plug
60.2MH/1354MH

5 cards + sys = (dual mining @ 30 DCRI)
600w @ plug
110.2MH/1652MH

5 cards + sys = (Dual mining @ 45DCRI)
620w @ plug
100.2MH/2264MH

6 cards + sys = (dual mining @ 30 DCRI)
730w @ plug
132.2MH/1964MH

6 cards + sys = (Dual mining @ 45DCRI)
745w @ plug
120.5MH/2710MH

EDIT: @ 6cards miner crash.....will investigate later....5 running for now.
Fixed by adding in setx GPU_MAX_ALLOC_PERCENT 100, all others have been removed

@adaseb

SOLO
using -20/800/1750/800
5 cards + sys

TEMPS:
SOLO

EDIT: temps held really well at 75, had different cards getting different air it seems so I have below the best and worst using the @45DCRI setting above

at wall 135w ish inc system for 1 card.
