they have not been used new equipment for many years.

That single statement tells me all I need to know. You just lied about about what you do and know. Enjoy your day at school

I apologise to all others who have followed this last bit and will stick to the topic now.
I would just re-iterate that this mod is not one I am trying to force people to make its obviously down to individual choice. I just believe the topic starter has a valid point here, SmartXX obviously thought so and Hippos new Sunday flash chips avoid the trace cutting and resistor mod at all, as up to now its the only chip with the features built in to avoid any possible issues if indeed any arise.

has anyone tested smartxx's "fix" for this or tested the sunday chip for that matter?

i think the reasoning behind that is becuase smartxx being the asses they are wont sell the rebuild board by its self you would have to buy the mod and im not doing that...

For those interested, I measured 62mA and 68mA on two different 1.6 xboxs

IF this ^^^ is true then there is something to it

the mcpx is constructed with sub micron silicon
and 60 ma is way to much current for it to last a normal life...
maybe 2 years or less instead of 10 or more...

Smartxx added a resistor and transistor in series (I think?) to their 1.6 lpc rebuild board, as a fix to this problem. But, I haven't seen any multimeter tests done using it or the Sunday chip like the test that had been done for x3, xenium ice, etc...

MrOnline · « **Reply #337 on:** April 03, 2005, 05:25:00 AM »

What are the outcome of this

1 What chip's / rebuilds solve this problem or does not have this problem

2 how many have done this and have no problem at all

3 how many have NOT done this and still dont have any problem ??

4 Are the best solution still to att a 680R 1/8W SMD (can i use 1/16W??)
and do it have to be ceramic, or can i use any Resistor

?

Ok, i had 4 BIG questions

Actually, that board they have for sale at extreme-mods.com is smartxx's 1.6B board. The 1.6C is the one with the "fix." It's blue I think.

I only got two questions,

Is anyone here an EE ?

(More of a statement) Im sure at least 1 or 2 of the people posting here will by now have access to documentation from some sources that will provide them with the nessesary technical specs of the Xyclops and Nvidia MCPX rv2 used in the 1.6 and 1.6b xbox's to provide a sufficient and final answer to the original reason for these some 39 pages. Who's gonna post the results.

oooh i just remmebered, with regard to the pulsing of lframe/d0. Anyone who's done or understand how logic things work understand what PWM is ? if you do you can see where im going with this. Almost all cpld based modchips have lframe/d0 going directly into the cpld pin, or to gnd via a transistor....see if you can figure out what im thinking.

and anyone got an oscillescope to verify this "pulsing" by the modchips in the starting post ?

Im happy to see people actually worried about this, as it can possible be a real serios problem, and also investigating the matter. What i find somewhat...stupid if you can allow that word to be used very vaguely... that its spreading like a big PANIC to everyone. Which it should not be. But hey..keep up the RESEARCH.

I have documentation that says it's overloading the CPLD. I have documention that tells how multiple flashroms coexist on the LPC bus. I have documentation on the process used to manufacture the mcpx and it isn't intended for these loads for longer than 1 second. I'm not an EE but I have an association with a game shop and do repairs and the repairs I can't fix I blame on the mcpx. It is considered the most sensitive chip and is often modded with thermal protection systems 'just because'. Catdog has provided a solution, Sunday chip has provided a solution, and SmartXX has adressed this aswell. Since the signal I designed for Sunday chip is a unique solution in that it works for all Xboxes it's safe to assume there were always alternative methods that work well just waiting to be discovered.

All I know is you can make 16 SST49LF020A's load a 4mb bios without gounding anything out so why are mod chip makers grounding out the other flashrom when there is just 2 flashroms on the LPC bus?

Everyone that doesn't go this is overloading their mod chip's CPLD pin by 50%. Obviously you could buy a new car, drive it 90 mph everywhere you go, even if it's just down the street for a pack of smokes and say it's not hard on the car at all, the car is still running fine. When the car dies the mechanic won't know to ask 'hey Mr, you didnt drive this 90 everywhere did you?' and he's not going to know why the car is dead.

Just like no one can tell you why the standby power transistors blow on the 1.6 after a mod attempt. No one knows why it's dead.
