Topic: any ideas to reach 300+Mhash/sec on a 6870 using Phoenix? (Read 2084 times)
My bad, edited the post. heh
Don't you mean 6950 running 6970 bios? Those numbers you posted can't be from a 6850 ...
an easy thing to try is to just add the WORKSIZE=128 flag
BTW, it's not necessary to jack up the core too high to hit 300Mh/s, I'm running a 6950 with a 6970 bios at 900/1250 with the voltage at max 1200 and I get 385Mh/s using phoenix and around 397Mh/s with guiminer. Both within Win7
Edit:
Phoenix ver 1.5 running phatk Device=0 VECTORS WORKSIZE=128 BFI_INT FASTLOOP AGGRESSION=11
Guiminer is July 1 version
Edit 2:
6950 flashed to 6970, doh!

Here's a simple script to help you set your stuff up.. just set your user/pass/pool-url info and execute.
Code:
#!/bin/sh
CLOCK_CPU=965
CLOCK_MEM=1050
FANSPEED=100
WORKSIZE=128
AGGRESSION=11
DEVICE="0"
KERNEL="phatk"
URL="api.bitcoin.cz"
PORT="8332"
USER="username"
PASS="password"
aticonfig --od-enable
echo "running: aticonfig --od-setclocks=$CLOCK_CPU,$CLOCK_MEM --adapter=all"
aticonfig --od-setclocks=$CLOCK_CPU,$CLOCK_MEM --adapter=all
aticonfig --odgt --adapter=all
aticonfig --pplib-cmd "get fanspeed 0"
aticonfig --odgc --adapter=all
aticonfig --pplib-cmd "set fanspeed 0 $FANSPEED"
echo "running: ./phoenix.py --url=http://$USER:$PASS@$URL:$PORT -k $KERNEL VECTORS BFI_INT FASTLOOP=false WORKSIZE=$WORKSIZE AGGRESSION=$AGGRESSION DEVICE=$DEVICE"
python ./phoenix.py --url=http://$USER:$PASS@$URL:$PORT -k $KERNEL VECTORS BFI_INT FASTLOOP=false WORKSIZE=$WORKSIZE AGGRESSION=$AGGRESSION DEVICE=$DEVICE

AMDOverdriveCTRL will let you mess with the clock and memory speeds. I run my 6870 at 1000 mhz and the memory at 350 which gives me about 310mh/s using poclbm.
what temp do you get on that?
what program did you use to change voltage and also OC?

there was a post on how to get a ~3% increase
http://forum.bitcoin.org/index.php?topic=23067.0
however you need more than 3% to get from where you are to where you want to be.
unfortunatly i don't see any reports of 300mhash/sec at stock clocks you're going to be doing some overclocking check here

and look at settings people ahve used on their 6870.

running stock voltages and clock speeds I'm only getting 265Mhash/sec
any way to get that up to 300 w/o overclocking? (don't want to shorten the life of the card)
if not, then what should i overclock/underclock to hit 300Mhash/sec?
