How should I go about replacing my logic board (MB4,1 -> MB5,2)?

I currently have a black Macbook 4,1 (A1181/2.4 GHz) with 2 GB of RAM.

OLD ::

It comes with FireWire, and cannot make any use of an eGPU currently. I am interested in finding out wether I can replace my current logic board with that of a newer , such as the Macbook 6,1 (White - Unibody), to make use of slightly newer technologies, while still keeping the same capabilities of (if not adding to those of) my current Macbook. This would also make future upgrades easier, in opposition to having to use MacPostFactor... The primary thing holding these devices back is their older GPUs (in this case, Intel GMA X3100), which is starting to cause some issues... I'm going to need to go parts-shopping...

CURRENT ::

I'm back from my shopping trip, and have just made a video about my recent decision. I looked at the prices for all component options. The cheapest prices for better RAM (20-30 USD/unit + shipping) and HDD/SSD (50-90 USD/unit + shipping) were a bit too high.

I managed to grab the logic board for approx. 75 USD (including shipping). Now I just need a heatsink and a MB5,2 Superdrive replacement.

In the video, you'll also notice that there is a wire that has no place on the logic board to connect to.

Here is a look at the original logic board:

A closer look at the area where the original wire would plug in...

A look at the same area on the newer logic board:

From what I've done so far*, it appears as though the orphaned wire was for an internal battery.

In addition to this, someone on eBay recently (approx 1 week ago) posted the Superdrive and Heat-sink/fan pairing I needed - for under 11 USD each. The thermal paste was under 3 USD.

How about posting a still image of the cable and describe what it is attached to.

I think you maybe hitting a wall here with the parts which is one of the issues you face when trying to force fit something that was never designed to do.

I will. Also, found this online:

It looks like someone pulled the move I'm trying, but I'm going to need to do some more research online...

Looks like a square peg and round hole problem! It just won't work. These systems innards are laid out very differently which is why this won't work.

30 de dez de 2016 por Dan

If the wire is coming from a legacy component (ie., the Superdrive, Bluetooth antanea, etc.), it won't halt the operation. That has already been arranged. Since it's not coming from the logic board, it can be swapped...

The wire was for a now-unused sensor. I'll be uploading a video later tonight about this...

If you want, you could replace the bottom case and logic board, then have a MacBook 5,2 so you can run El Captain or Sierra if you can do a little hacking :) The bottom case heatsink mounting screws are in different locations, that's why a said replace both.

What is needed on a 5,1 to make it Sierra eligible?

15 de dez de 2016 por Matt Van Every

A 5,1 is a unibody model, it will not fit in the casing.

@gigabit87898 You need to explain just how to do this "little hacking" before talking abut going to Sierra on a pre 2009 machine, because outside of the MacPro 2009, I don't know how to do this ;-)

16 de dez de 2016 por mayer

El Capitan (10.11.x) is the best you can go up to. Due to the systems memory limits I think its just better to stay at Mavericks (10.9.x) If you can. I wouldn't even try hacking it to run Sierra (10.12.x) its just not worth it.

I don't believe you can replace the logic board with a newer version. As of early 2009, they essentially began constructing MacBooks Pro's logic boards differently (i5 & i7 series CPU's) so that any and all upgrades were impossible. I have held onto my Unibody late 2008 model just for this reason.

Though I'd not replace a logic board, I would absolutely replace the HDD for an SDD and upgrade the RAM. Wait until you see the difference between 2 GB of RAM and 4.....it's like a totally new machine! If it's possible to modify...

Good Luck!

I found this on one of the other pages:

Swap late 2008 Black MacBook logic board to Mid 2009 logic board?

and this list of candidates for the theoretical swap:

http://www.everymac.com/systems/apple/ma...

Unfortunately, can't go any further due to logic board differences and port changes. Also, all of the candidates come with slightly less processing power :(

Any suggestions?

Like I mentioned, I'd look at upgrading your RAM. You've got the 2008 model so you cna make changes. I'm telling you, I think you've got 2GB standard, and 4GB alone will BLOW YOUR MIND! No joke...... I also would go ahead and upgrade to the SSD. This is a more expensive upgrade, but both are worth it.

Start with RAM though...trust me, you'll never regret doing so. I was able to find a way to increase my RAM all the way up to 8GB, so I did that eventually. Honestly, the 4GB to 8GB upgrade was nice, but interestingly enough it didn't have the impact that 2GB to 4GB did. Just wait until you boot up the first time after you've increased from 2GB to 4GB...it will get to the desktop in 1/3 of the time, maybe even less.

I'll consider it. Just wiped the HDD today to try a reinstall (10.7.5, from 10.10.5), for performance check. Already backed up everything, so didn't lose anything. I'll be back with my results...

15 de dez de 2016 por TopHatProductions115

The max RAM this system can support is 6 GB using one 2 GB and one 4 GB memory module. While you can use two 4 GB modules the last 2 GB of the 8 GB is not accessible to the system (6 GB is all the system can use).

I think you should save your pennies to buy a newer i series CPU based system.

16 de dez de 2016 por Dan

Yes, getting an SSD has worked wonders for many Mac people. Better than a motherboard replacement anyday. Get a 240 or 480 GB SSD. I highly recommend a PNY SSD over the more expensive, bigger brand competition such as Samsung. Also, a couple more gigs of ram would be leaps and bounds. Hope this can suffice as an answer to your question.
