[HOWTO] flash your jalapeno to 8+ ghs

[Ex0deus]

Thank you for this wonderful information.
This is going to come in handy in fighting that difficulty monster when my jally's finally arrive.

I appriciate all the hard work and sharing of info

Greats

Before Jalapeno 1: 5.5GH/s : After Jalapeno 1: 7.7GH/s

Setup for flashing Rev 2 Jalapeno with all aluminum heatsink.

Just tweaked the firmware. changes ln 101 in std_defs.h

Code:

	#define __ASIC_FREQUENCY_ACTUAL_INDEX   9 

New Speeds  

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

Nice tweak! Thanks for that And by the way. Nice setup for your flashing too

what kind of cooling are you using for the increased power?

[-ck]

Most of them will be overloaded by hardware errors at speed 9. Most peoples' Jals will work best at 7 or 8.

Cool guide.  Got one for us Single owners?  OH that's right only about 10 people have their Singles at this point so what's the point?

Don't rub it in

I meant to say Got One for Us Single Preorder Owners

BFL being awarded the Most Professional Company ever award just decides to ship Jalapeno's and completely disregarded their other product line

So does the average hashrate reported by cgminer considers hw error or do we have to account for hw errors by some other method?

Ckolivas: help myself and others  understand this if you could. (Or if you know)

What makes a jalapeno have 26 or 27 or 28 or 29 or 30 engines out of the box?  Mine is one with a 2Gh upgrade and runs at 7.2Gh out of the box.  What im wondering is, is there a reason mine has 27 engines on and someone else has 30?  Is it your opinion that BFL simply turned on enough to get me to my required purchase of 7, or are my chips really only capable of 27 engines?

I realize you might not know the answer to this, but im curious.  If they tested and binned the chips, then my chips are not nearly as good as some i see people talking about here, and theres little need for me to try and eek out less than anither ghash.  If, however, i can unlock 3 more engines, i'll probably give it a whirl.

How many engines did yours have originally and have you had issues turning on more?

Does anyone else have 27 or less engines ?

[tom99]

No body what are grade chips you will get on Jal and most Jal wont get grade A chip. 

[derr777]

Yes but ckolivas implied we could turn on 30 and it might be good..  Im wondering if BFL actually binned the chips before setting firmware, or if the firmware itself determines how many engines are working acceptably, or if i just have two grade C chips, and i shouldnt buying a dragon..

Im not sure is all..

The firmware tests the engine (and chip if you have multiple chips) performance at startup and adjusts the speed accordingly based on how "correct" the answers are from each engine. It is not unusual for the existing Jals out there to be somewhere between 27 and 30 units when run at the higher speeds. 30 is the most that can be activated on 2+ chip units. When run at their lowest speed as 5GH units, most of the engines seem to work making all 30 start at 189MHz ~5.7GH. I posted firmware which relaxes the test dramatically making it far more likely to activate all 30 engines at speed setting "7" which is 274MHz, so 30 engines at 274 ~8.2 GH.  I can't comment on the binned versus unbinned policy for chips by BFL but it looks like earlier units were unbinned making them potentially full speed, while later ones were chosen to reach the guaranteed speed as a minimum.

Unfortunately some of the hardware errors are currently counted towards the hashrate so you cannot simply look at the hashrate and determine whether you're creating all good work. I'm planning on rectifying that next cgminer version.

Good 

[derr777]

much appreciated ck...  Thank you for the info,and for the great work you do on a piece of software I use daily and appreciate greatly..  Looking forward to future versions.

[ooxtcoo]

so for thus who dont upgraded till now from 5 to 7 gh/s jalapenos.

should we upgrade our jalapenos or should we let it like it is and just overclock?

are the chances better to get better grad chips with the upgrade?


btw. i dont think you need a dragon to programm a simple avr.
just build a serial cable and you are ready to go...

avrs are very simple interface and if you have old motherboard with serial port, thats all you need.

or you can buy some simple usb mini avr programmers for some euros only.
they should also work.

i post you later a simple shematic for the avr cable.
its realy easy cable with no electeonics needed (some resistors would be good but not needed).
i programmed many flasher boxes for phones with that already.
this boxes had atmega 8 and atmega 128 chips on board.

Can you be so kind to please post the code to the modified firmware, since I want  to test my Jally at speeds "9" and using all engines.
