RX 470 = 30Mhs ++ GPUz 80W

New settings as in attachment ... will try it out and see how long it last.

Post like this are pointless...I have my 470s running at 31mh but it does not mean its stable. Run this for more than 24 hours without it crashing a dozen times.

[adaseb]

8gb correct?

[mewhoyou]

Nope... its a 4GB card

Agree with you ... will run it for 24 hours and will see if it crashes.. so far 2 hours in ... still standing great.

Push "S" and see if you have any incorrect shares

[Tmdz]

Sometimes you can get lucky with the memory chips, 2100 mhz is a really high OC.

You might be able to even push it to 2200 mhz, but Im not so sure what effects long term that will be.

5 hours in and has 2 incorrect shares not reboot nor gc crash ... if this works all my cards are changing

[mewhoyou]

9th hour and yet no reboot nor crashes.. Incorrect of shares is at 10. Should be acceptable running at 30mhs constantly..

24-48 hours are not enough some times, i remember a case were the crash occured after 3 days, you need to run for one week to be 100% sure

and btw gpuz is incorrect, it's more about 100w not 83

[adaseb]

What voltage is your Memory Voltage set too? 1000 ?

[mewhoyou]

its stack on 1050.

Yeah ... will let you guys know .. btw i am running these two cards directly off the mobo and no raiser.. this is my pet project.. my farms are on a safe 28.5mhs.

I had mine doing 29 MH by following this video but it wasn't for long mine got really unstable at that  speed or mine were . mine are 4 GB  Cards .

I'm sure i Probably could have tweaked it enough to hold at 29 MH or higher if i tried .

https://www.youtube.com/watch?v=uy0roLG7ARc  got bored real fast tiring to many crashes .

[yslyung]

heh, 3 mins ... don't kill your card, let it run where it's stable & MORE importantly don't suggest or show the public something which is not useful or cause harm or damages to others.

just my 2 cents, flame if you want.

although if it's "stable" for 24 or 48 or even a week, did you ever look at how MUCH memory errors it's generating ? prolly higher than bitcoin current diff now.

post a screenshot of the memory errors heh...

peace out.

i'd suggest to fine tune the gpu to the lowest possible memory errors with lowest power & you WILL most likely end up around 27-28 mhs STABLE

There back to default clocks with the mode i redid @ 27 mh and Ming a way.
I need those cards to much right now to burn one out .

http://imgur.com/1sGfiPU  or clocked it to 28 MH gonna see if that holds ok for a while with one card if it does I''ll put my other 3 at 28 MH , 29 MH was a nite mare for me .



Great, if the OP does get it to run stable @ 30 mh.


Thanks top.

for 29 MH i had 0 incorrect shares in 24 hours but 30 mh i had about 10 incorrect shares a day .. i wonder how much would that effect the end result.

What is your total number of shares for 30mh?

(incorrect shares divided by total shares) * 100
gives you the waste rate in %.

24-48 hours are not enough some times, i remember a case were the crash occured after 3 days, you need to run for one week to be 100% sure

This is unclear.
Let's suppose you have 150MH on your rig and by running "unstable" you get additional 3MH total. If you have ssd and miner on autostart it would take say 3 minutes until it's up and hashing.
Five restarts a day make for 15min*150MH = 2250 MHm of lost hashes
so even in this case you still get positive result: 60*24*3 -15*153 = 2025MHm which is still almost 1% increase of total output

For me if a crash happens, then it's usually a hangup and the PC does not reboot automatically, and what is more it's continously drawing 350W while hung.

This can be cured by having USB watchdogs. I already ordered the arduinos to make some... not that my rigs are not stable currently.
