Tell you what though, this advanced tuning lark is a bit addictive.
anything performance wise?
Well whats interesting is that, if you remember, I kept going back to 0.96 because the newer firmware just kept flapping the cores on and off.
So installed 99-Tuning, left it alone for a while and sure enough flap,flap, cores off all over the place and Avg dropped to 529 and dropping slowly.
Well I found with the tuner that it was mainly ASIC1, Die 1,3&4 that were affected, so I've been tweaking them back to 100% on status, using the individual core voltage control.
Bit hit and miss, I went way too far to start with on the voltage and actually had some cores turn off, but started again with a bit less elbow grease and its beginning to come together.
I'm talking it slow, but I've seen some sustained 630+ Gh/s for quite long periods of time. But the flushwork performance drops, although alot better than they used to be in terms of how long they last, because they drop as far down as 300Gh/s, would keep the average below 600 even if you could maintain it for any length of time.
But its a bit like overclocking cpus, very much up my alley having the tweaking ability like this.
oh and 0.4 of bertmod works with it (except you have to remember the advanced_settings.html URL)
