What's the overhead compared to windows?
In order to get the best from your hardware,overheads from the OS need to be kept to a minimum.
I'm not sure exactly what "overhead" refers to here... BAMT uses less ram and probably has fewer things contending for I/O and cpu time than the typical Windows installation. However, if or how that would actually effect a GPU's mining performance I'm really not sure.
Given a reasonable aggression, your GPU should stay fully loaded regardless of what else is happening on the machine, within reason.. long story short, I doubt any measurable difference would be seen in hash rate between a properly configured machine running either OS. The driver version and SDK version probably have more effect on hash rate than the OS you use in most cases.
I ask this because I get 400MHash/s from HD 6950 (shader unlocked,core clock OC'd to 895MHz stable and mem clock 949MHZ as going any higher on core clock and lower on mem clock destabilises my system.
Can I OC my card to those setting in your OS?because thats what t takes to raech 40MHash/s on my card.
Yes, overclocking is very easy in BAMT.
If this OS is lighter than win 7,then my performance will be boosted even more
I wouldn't count on it.. but worth a shot. I'm interested to know either way.
What about power saving options for when I need to check my email briefly before resuming mining?
thank you
I don't quite follow you here.. BAMT is for dedicated miners, it doesn't provide user applications. Technically there is a web browser, but it's just there for administrative tasks. Check your email with something else would be my recommendation.
Good luck
