Overclock settings for an 5770

[bonker]

Anyone got any tips on the best over/underclocking numbers for a 5770? Ive got 170MHs from clock settings of 900/1300.. anyone top that?

I too am getting in the ballpark of 170-180 M/hash with the same clock settings. The "-v -w128" flag seems to help a little bit. Though after a day and change I only ended up with .08 BTC from deepbit.net's pool using the PPS option.

I have 5x5770's and am getting anywhere between 200-220 depending on the overclock.

XFX - 1000/300
Sapphire cards (x2) 1000/325
HIS cards (x2) - 950/400

How much BTC are you pulling in a day and what pool do you use? Or are you solo?

using a cheap 5770 here. soon as I go above 950 it starts getting a little unstable. but on 200mhash atm you get around .23 BTC a day

Heres what my MSI Hawk 5770 is doing and its settings. Thats literally as far as I can push it ... anymore voltage applied or core clocks increased and it crashes.

I can post my miner settings as well if other are interested.

I am running a sapphire 5770 vapor-x. I have it at default max clock of 960 and the memory at 600. I found these settings give me the best results.
I pull ~200MH/s with switches -v -w 128. Bitpool reports my MH higher but I thinhk their results may be erroneous.
I have found that I had hangups when using auto fan control but swtiching to manual seems to fix it.

only about 0.1 Btc/day at bitcoinpool might jump ship

Im getting about 0.3 a day at btcguild with my setup.

Using phoenix on GUIMiner, heres my flags which result in a very consistent 226 MH/s

Code:

VECTORS BFI_INT FASTLOOP=false AGGRESSION=14 WORKSIZE=256 -k phatk

yea for some odd reason opencl is just a little quicker for me using -v -w 128 -f 0

On linux I can overclock my HD 5770 cards to 202 MH/sec 960 MHz.  I use poclbm with -w 128.

linuxcoin is my OS and I have a startup script ....

DISPLAY=:0.0 aticonfig --od-enable
DISPLAY=:0.0 aticonfig --od-setclocks=960,0 --adapter=all
DISPLAY=:0.0 aticonfig --odcc --adapter=all

cd /opt/miners/poclbm

./poclbm.py -d0 --host=uscentral.btcguild.com --port=8332 --user=XXXX --pass=YYYY -v -w 128 &

./poclbm.py -d1 --host=uscentral.btcguild.com --port=8332 --user=XXXX --pass=YYYY -v -w 128 &
