Greetings

ALL SOLD OUT!!!

Some of you have been wanting to upgrade to 128 meg of memory, for your Xbox. The extra 64 meg of memory is great for Linux, MAMEoX or software development.

4 chips are required to upgrade from 64 meg to 128 meg. 2 on the top and 2 underneath.

I found another place that offers XBOX Memory Chips in Germany. They are selling them for 64 Euros (~$75) + shipping.

Soldering these chips requires very good soldering skills and tools. There are 100 pins per chip!

Here is an instructional site, that has a video clip, showing how to solder SMT chips.
Or you can look at this site.

Here is a previous thread from Xboxhacker.net, where people have successfully added 64 meg to their XBOX.

NO REFUNDS or EXCHANGES. ALL Sales FINAL.

Dink...

Update: 0 sets left

Good guide, though.

going to bump this. The memory works great with MAMEoX, and from past experience Dink is very reliable. I have worked with him in the past, and would work with him in the future.

Any tuts on how to REMOVE the old chips? The two tuts on soldering the new ones seem easy enough but removing the old one... -- any tips on that?

If you are thinking to remove memory chips from another Xbox, make sure you get at least video output. The memory is shared by the GPU and CPU. No display, could mean bad memory.

As for removing them, I use this rule of thumb.
If you want the components, you sacrifice the PCB.
If you want the PCB, you sacrifice the component.

Trying to save both is very difficult, especially with so many solder points.

Personally, I use a propane torch. Others have used a heat gun, both methods destroy the PCB. Heat gun is cleaner.

As for soldering them back on, the best approach has been the solderwick.

Good luck

Solderwick as in using the desolder braid?

- I'm actually wondering about removing the old memory chips in order to replace them with these new ones so saving the PCB is crutial, the old chips can go to hell. wink.gif

So do we have to desolder these chips? or are they already desoldered, and ready to be soldered in? I will take a set, if you have any left. PM sent. Have these been verified to work with the xbox? You can IM me at Marimite00 if you wish.

You're not removing your existing memory and replacing it; you are ADDING these memory chips to the four unpopulated memory pads on your motherboard.

does it matter in which direction they are soldered in, as in, do the chips have a front and a back? or does either way work?

That video really does make it look easy. I was going to add solder, glad I watched the video first.

All chips have a pin 1 mark. There is usually a pin 1 marking on the PCB too. All 4 empty memory spots are the same. Each chip takes up 1 memory location on the PCB.

I recommend try soldering some other SMT chips first before doing these. e.g. Take an old Video card and slowly apply heat to the back side with a blow torch. The chip will fall off. Then clean the pads with some solder braid, and then try re-soldering it back on.

Once you thin you are ready, start soldering the memory chips on the back of the Xbox MB first. Less components to get in your way.

If anything, you need to take away solder. On the most of the MB I have seen. If you look very close and feel the solder pads, you notice a small amount of solder, on each of the pads. This is plenty of solder to do the job. Be sure to add some flux to the pads first.
