Maybe their nothing at all but it doesnt help to completely ignore them

also the square chip bottom right of the picture in the 1st post maybe network/sound ?

He's right, can someone with some technical knowledge tells us what anre those chips and can they be useful in some way in the boot process?

I'm not on the frontlines of the hacking scene, but I've seen enough computer parts to know that those are RAM chips. Many RAM chips for PC's have the same markings. I wouldn't put a lot of resources into those.

OH MY GOD

ok EVERYONE look beyond the samsung ram like i said in the second post maybe i should black out the samsung ram
becouse peaple here obviously get blinded by the big pretty ram chips for gods sake theres about 20 different chips on the bottom of that board excluding the damned ram.

OK BEFORE YOU LOOK AT THIS PICTURE DO NOT POST ABOUT THE SAMSUNG RAM CHIPS CAN I MAKE THIS COMPLETELY CLEAR "IM NOT TALKING ABOUT THE SAMSUNG RAM"

most of those things arent important, there on various pc parts, my motherboard has ones like you circled

reason ur not getting answers is the smart people know there not important and are not wasteing there time

well part numbers would be nice but ignorance wasnt

all the peaple here had to do was read and not write .

its just some ics used in the electronics. if you give me what the chip says i can tell you what it does, but its not something that would help with hacking. its just for the electronics, i.e. gates, timers, etc.

we need to focus on eeprom and tsop if we want to get anywhere

Might it also be possible to replace these memory-chips(Samsung) by larger/faster chips or is that "limited" by the memory controller. A Simular mod was also available for the "old" xbox.
Only before this upgrade was noticeble when you run Linux, all the games didn't allocate the extra memory.
2 bad i don't own a xbox360 yet! However if somebody can supply me with the all the chipset-numbers i would be greatfull.
Most pictures posted are not sharp enough to read this, but are crutial for hacking "the box"
(else everybody has to loose there warrenty just to read the chips)

reagards,

MassaReal

btw: Don't think the CPU needs a upgrade, only VGA, but that's 2 much work.
(new VGA-bios+extra cooling?)

Most of that is normal surface mount analog circuitry like resistors, capacitors, transistors etc.

The smaller IC towards the edge of the board is probably an eeprom or some smaller memory device for holding basic system instructions/information. The other ic by the eeprom looks like a voltage/current regulator.

the ics by memrory towards the right can be anything like an ethernet controller or the BIOS chip.

it's pretty hard to determine what a chip does without a datasheet to look at.

You could put in faster memory, but only if the pin layout was exactly the same, and even then there is no gaurantee that it will work. Your timing would be off and you would lose data on clock edges and you could also be creating data that really isn't there by shifting the read/write timing.

Just because you put in a faster chip in a console it doesn't speed up the memory bus because the clock is still going at the same speed.

Larger memory would probably have a better chance of working, but that depends on how wide the address bus is on the 360. If it can only address 512mb, then it won't matter but if it could address 1gb then you could use it. I doubt 360 games would take advantage of it though. The same reason why games on the original xbox don't use more than 64mb of ram. Simply put, they aren't written to use that much.
