...dynamically resizes the persistence partition to the size of the key.  It may work on 512MB key, it will definitely work on 1GB keys.
Excellent!

Take your time, but you know, maybe you´ll start first by using that 125 difference.
I had my cards flashed to a lower mem and frankly is not THAT much improvement.
940/815 is not that bad.

940/815 is not possible with my cards. i can only go 100 lower. so now they are running at 940/840 with 290mhs
but the temp is what i am worryed about... now with 100% fan temps are 62 to 77 so thats a bit high for actual time and temp outside. i do not want to know how much they are when its hot outside. my miner stands outside in my balkony. so thats why klima affects directly. but under windows fans where automatic and mostly on 60% but temp of cards was lower... only when it was extremely hot outside they went up to 84.
btw i am alway wondering how much they can have until pc restarts or cards die. will linux also stop mining when cards go to hot?

Weird, this 125 difference is working for my 6xxx.
If temperatures are worrying you, yes go with the bios flash.

The default BIOS setting in most 6xxx cards is a lower limit of -125 difference.
... I would have said ALL 6xxx cards except you seem to have one that isn't Smiley
So with cgminer you use --gpu-memdiff -125 on 6xxx
(of course you need a collection of other options too)

I am curious about those high temperatures, what physical setup do you have?
You have the cards in a closed/open case or in an open rig with cards wide apart using extenders..etc?

6870's are engine -100. I set --auto-gpu --auto-fan --gpu-engine 950 --gpu-memdiff -100 -I 9 and forget about them for weeks, they clock down a bit during the day and go back up at night, and they never crash.

OK yep - silly me Smiley Wrong again Smiley I guess I should have said 69xx
Is it all 68xx are -100, or no one knows?

I have them in an open banana box made of wood. I use extenders so one card is directly on the board and the others are above with about 3 cm space between each. More place i do not have. Now over night they came down to 74 the highest temp. So i will have an eye on it.

Thanks lodcrappo, that is good to know.
Have another question: how big the new BAMT will be?

Why I am asking this, the old BAMT that was meant for at least a 2GB stick was in fact too big for some 2gb sticks, which were in fact 1.8GB.
I always had to shrink the image prior to load it on my stick. So maybe you could make the image a biiiit smaller?
Something like 1.7GB or eventually 3.7GB whatever is the case.

bamt 0.6 has much smaller requirements and dynamically resizes the persistence partition to the size of the key.  It may work on 512MB key, it will definitely work on 1GB keys.


AWESOME news!  Now if we could PXE boot...

That came out a day or two after BFL announced their SC line. It's just a spoof.

Is there any way to figure about the CPU temperature and speed?
My CPU fan has been running unusually high and the thermal paste was applied horribly.
I cleaned the fan from a ton of dust already.

Yes

Awesome - are you running a 5 or 6 card setup?

Is it possible to undervolt in BAMT?
