5970 hash rate problem [1 btc reward for solve][solved]

[jhansen858]

Hey guys

I'm reading that I should be able to get 650 MH/s on a ati 5970 from https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMD_%28ATI%29

However i'm only getting [303.59 Mhash/sec] [54 Accepted] [0 Rejected] [RPC (+LP)]


I'm offering 1 bitcoin to the person who can get me up to above 550 mark per card

I'm using linux ubuntu 11.04

2x 5970 ati video cards 2mb ram

Thank you!

Yeah 600 and something is the average with a 5970.
Which miner are you using?
Did you try with the latest ati drivers and OpenCL runtime kit?

i used this guide to setup

doesnt 5970 have two cores? maybe you're only using one. 300 sounds very low...

First off, what have you tried so far?  Have you tried the various flags listed next to your card on that page you linked?  What about overclocking?  Let me know where you stand right now so I have an idea of how to help you.  

[richwest]

I imagine your problem is that the 5970 has 2 cores, so you need to run two instances of your mining program (one per core). So if you have 2 5970s, then 4 in total. For poclbm you add the "--device=0" flag to your command line and change the number to accomplish this, so start one instance with --device=0, then an instance with --device=1 etc.

If that solves your issue please send the bitcoin to 12aw3CRAtKQoT2skZ9CF2ea2jVHFARqCep and it will be gratefully received!

What temperature does the cards reach? If there is a case of overheating, the card will donwclock itself automatically to prevent damage, lowering hashrate in the process.

Two instances of whatever mining client you're using per card.

Run 2 clients per device. that is just run 2 seperate instances of phoenix on device 1, and 2 instance of phoenix on device 2, also up your aggression.

when i do this, my hash rate just goes in half for each ...

89 degrees feels like it's getting near the edge of what's safe, so you should downclock the memory on both cards to save power and lower temperature.

[LlamaMaster]

This isn't the main problem, but it will still help your speeds.  I judging by your clock speeds it doesn't look like you have done any kind of overlocking.  Open up the Catalyst Control center and go into ATI Overdrive.  Turn your memory speed all the way down, and GPU clock as high as it can go without crashing.  Also turn up your fan speed to max and try your best to keep your card around or below 90C.

I think my problem stems from the fact that some how i'm not able to access all 4 cores and maybe i'm only getting 2/4 to work..

if someone who has this same type of setup could post what they are seeing when they run those commands above that might help me to confirm that...

[jhansen858]

@richwest

your suggestion seems to be what i'm having the problem with, can you give any further guidance on this?

[dingus]

maybe you need to set the --platform flag to 0 or 1.

[anodyne]

I know 5870/50 start the thermal throttle at 100°C, but maybe they cut it 10 degrees lower as an extra precaution for the 5970?

I guess the question to ask is if you see a decrease in hashrate after you start them up.

[Eikill]

This is what I'm using and it works for me. Add this into a text file, save it as a .bat, put it in the directory where you have your miner and run it.

Code:

@echo off
start phoenix -u http://username:password@pit.deepbit.net:8332/ -k poclbm DEVICE=0 VECTORS BFI_INT FASTLOOP=false AGGRESSION=11 WORKSIZE=128
start phoenix -u http://username:password@pit.deepbit.net:8332/ -k poclbm DEVICE=1 VECTORS BFI_INT FASTLOOP=false AGGRESSION=11 WORKSIZE=128
