look like your Jal 1 asic chips not good grade chip and Jal 0 look good. 



ps: to get getinfo work u need to run cgminer config setting with api



Then how can I get the API info? Can it be done with a browser URL? Thanks

a) a tiny hex screwdriver to remove the screws off the bottom of the Jalapeno

Btw the correct terminology for the required driver is Torx T9  Grin

Before Jalapeno 0: 6.2GH/s : After Jalapeno 0: 8.6GH/s
Before Jalapeno 1: 5.5GH/s : After Jalapeno 1: 7.7GH/s

Very good. You must have 30 (or more) engines on Jalapeno 0.

How can I get the stats of engines? I would want to know that. Thnks

@goxed What kind of temps are you getting with those aluminum heatsinks from the getinfo command? Is it a nice drop off from the original cooling solution?

those are just for use during flashing. It will kill the Jally for sure if used as a replacement after flashing.  Smiley

Setup for flashing Rev 2 Jalapeno with all aluminum heatsink.


Cool!
Have you tried tweaking the firmware?
Just tweaked the firmware. changes ln 101 in std_defs.h

Code:
	#define __ASIC_FREQUENCY_ACTUAL_INDEX   9 

New Speeds  Wink

Before Jalapeno 0: 8.6GH/s : After Jalapeno 0: 9.2GH/s
Before Jalapeno 1: 7.7GH/s : After Jalapeno 1: 7.9GH/s

Code:
 [P]ool management [S]ettings [D]isplay options [Q]uit
 BAJ 0:  max 35C 3.76V | 9.213G/9.197Gh/s | A:171 R:0 HW: 7 U: 22.82/m
 BAJ 1:  max 41C 3.50V | 6.986G/7.907Gh/s | A:150 R:0 HW:35 U: 20.01/m

Do they get lifetime warranty?
Maybe not after you mod the firmware and push it hard.  They certainly would not be required to do so. 

I imagine when these break because of overclocking they will have a pretty similar characteristic.  So if you are doing this, know what you are doing, don't go crazy, and you MUST upgrade the cooling.  This includes all parts further stressed by more heat, not just the ASIC chips themselves.
Yes this is really a Jalapeno only option coz they only have 2 chips.

The later devices, 25-60GH/s I'd firstly be surprised if they could be clocked much faster, and secondly be worried that it would kill it very quickly without major work on the hardware cooling.

Obviously they will already have the 1.2.5 or later firmware so this simple reflash wont make any difference, but messing with the firmware to clock it up higher ... I can see ASIC death and destruction on the horizon with the bigger devices Tongue

What damage does this do to the lifespan of the Jalapeno?
Void warranty... nothing else...

Hodl!
and -5 To Armor Class and -3 to Constitution.

But seriously the jallies were released at well below the design speed of these chips. As long as they're kept cool there should be immeasurable impact until you start trying to hit 10+Ghz on a 2 chips with extra volts and bus speed or something.
