[HOWTO] flash your jalapeno to 8+ ghs

[erk]

Sorry if I missed it already, but can someone tell me the change in power consumption, measured at the wall, of the 5GH/s Jalapeno before and after the firmware re-flash?

In my case ~32W to ~46W
going from 6.4GH/s to 8GH/s

So ~44% power increase for a ~25% hash rate increase

N.B. my Jalapeno is one of first few of course.

Thanks, 46W is still not too bad, for an overclock.

Ya that's in line with what I'm getting: 45W

Is it now using a higher voltage when it's overclocked?

NFI
The SC is reporting it lower, but that's the on board info which is probably pretty unreliable.

And since I cant count ... I finally realised I got the numbers wrong

That should read:
In my case ~32W to ~46W
going from 5.4GH/s to 8GH/s

So ~44% power increase for a ~48% hash rate increase

Done mine, alu heatsink
getting ~7.2Gh from ~4.9

I used the northbridge heatsink off an old mobo and some thermal paste - no burnt fingers

Grats. It's not a bad hack actually, more interesting then just buying a unit and having it sit there. I only ordered in April, and with the current ship rate, it will be months and months I think, before I get to do the hack.

So this is less of an overclock but more of a get what you really paid for upgrade.

Thanks all for the firmware unlock.

And there goes the overall hash rate again

With everything there is a price, you don't know how much the life of the chip is shortened by generating 40%+ more heat.

You are right. Extra cooling is necessary for all overclocks.

Lifetime profitability of said devices may dwindle faster than the over cooked chips in question.

You would need a crystal ball to tell that, most people fixate on the exponentially rising difficulty rate, but they forget that one good spark and the BTC price could skyrocket. It's only if the price remains flat the difficulty is an issue, in either case I would want to look after my ASIC, perhaps a better fan setup, certainly a good thermal compound between the chip and heat sink.

Here is precompiled firmware that will try to enable all the engines for you if you can't get up to the ~8.2GH that should be doable:

http://ck.kolivas.org/apps/cgminer/BitForce_SC/BitForce_SC_1.2.5ck.elf.zip
(Unzip it and load the file BitForce_SC.elf into the "Flash(128KB)" box after the step where you click on "Memories" as kano posted above.)

It's just like the old unlocked shaders thing with 6950s, some of them will just run like 6970s anyway. Usual warnings apply, but I am using this firmware on my own, so it's not a precompiled brick.

The voltage would be expected to drop off a little when drawing more current if the power supply is approaching its maximum power rating.  There is no way the voltage would go up, unless you could tweak that in the power supply itself.

PS: Thanks so much for this whole thread :-)
although my dragon is gonna arrive weeks before my BFL kit and make me sad :-(

Don't forget how long BTC was in the sub $10 range. Very few people thought we would ever see higher than $30 again(was a extremely short lived price at the time). Current state of the market is not so great.

But enough with the off topic. Lets not muck up this thread with nonsense. This thread has actually been staying surprisingly on track and to the point. A extreme rarity on this so called 'forum'. I'm even kicking myself for even replying to your post.

What cooling modifications would you guys recommend to extend the lifespan of this Jalapeno with upgraded firmware?

I really don't want this to cut it's life short

Take the cover off leaving it on the stand only and turn the fan upside down.

what model of jally you test this firmware? the old with copper heatsink or the new ones with the aluminium heatsink?

Both.
