Title: Mining on the 5770
Post by: mattpker on June 01, 2011, 04:25:59 PM
I found some great information on mining with the 5770 at the following blog:

I was able to duplicate smpake's results on my own XFX 5770.

I have a strange result...

I have a 5770 Vapor X and I have a regular Sapphire 5770.

The regular one pumps out 195MH just fine.  Howevever, when I bump up the clock too much on the vapor x, it will hang.  So my vapor x runs around 150-160, and the non vapor x runs @ 195.

I haven't tried messing w\ voltages or anything, was just using catalyst control center.

I have 2x 5770s, With no core voltage changes (mem @ 275 & OC to 960), I run Phoenix poclbm at aggression 11 for 214Mhash & aggression 7 FASTLOOP (main vid card) at 208MHash.

I have (2) Sapphire 5770s running with no voltage changes (can't seem to change them in overdrive or afterburner).  I'm running current version of CGMiner, aggression at 9.  I'm able to pull memory at 300 for both, OC to 1002 on one, and 992 on the other.  I think bus voltage begins to sag and generally the second GPU drops.  Able to pull 232 & 227.8 for a combined rig total of 459.7MH/s!

I have 1 5770 running on my main machine
it gets avg 188. using CGMiner
i don't overclock it since this is also my work machine and don't want any crashes...
