1.8 EFI firmware update gives 8Gb possibility to MacbookPro 5.1 ?

It came through in software update for my 13" Alu MacBook.
The noise never bothered me so I'm not going to bother testing whether or not it worked.
Definitely not 8GB though.
I think a firmware update can in fact change it, its the exact same chipset used in the macbook pro's.
Nope...non 8GB MBPs use a B2 version of the chipset whilst 8GB MBPs use a B3 version
I just updated the firmware followed by the super drive update on my 17" uMBP. The super drive clicking noise is gone when my rig comes out of the sleep mode.
I have the 5,3. Can't i fully use 8Gb of RAM already ? (lets suppose i run enough apps to need them)
I dont see the update on my 15" (5,3 bought in august 2009) , but i havent updated to 10.6.2 (im still on 10.6.1).
Out of topic: What is the difference between 5,1 5,2 5,3 5,4 and 5,5 ? I havent found the info anywhere
MacBook 5,1 - Aluminium MacBook
MacBook 5,2 - 13" White MacBook (Early 2009)/13" White MacBook (Mid 2009)
MacBook 6,1 - 13" White MacBook (Late 2009)
MacBookPro 5,1 - MacBook Pro (15-inch, Late 2008)
MacBookPro 5,2 - MacBook Pro (17-inch, Early 2009)/(17-inch, Mid 2009)
MacBookPro 5,3 - MacBook Pro (15-inch, Mid 2009)
MacBookPro 5,4 - MacBook Pro (15-inch, 2.53GHz, Mid 2009)
MacBookPro 5,5 - MacBook Pro (13-inch, Mid 2009)
Yes, that is exactly the noise. After the superdrive update the noise coming out of sleep is gone (thank you Apple) but I still hear it on boot up (probably normal). I noticed the odd noise immediately when I first got my MBP because I had been using a MBA which was always whisper quiet when waking from sleep. I thought it was just a normal noise from the optical drive but now that it is gone I am really happy.
* Apple recommended a fix involving inserting a CD half way in and pulling it out to reset the drive and fix the noise but I could never get it to work.
Oh - I still got it on boot up and thought it did nothing - haven't tried a sleep yet.
From iFixit:
17 MBP (...and every other MBP revision that came out after that)
15" MBP Late 08
13" MacBook (Late 08)
Enjoy

Yes, but what does that prove? What you are repeating is nothing more than a theory.
Updated - same usual SuperDrive noises?
Yes I did update the SuperDrive firmware 3.0 after that too.
Mine still makes the noises upon boot, but is now completely silent when I wake it from sleep. At least it's a 50% improvement.
What theory, its a proven fact that macbook pro 5,1 cannot access > 6gig. No amount of patching will resolve this, its a hardware issue in the chipset. Perhaps if apple wanted to invest in a lot of time and effort it could be overcome with a firmware update, but why patch something they don't even sell anymore to achieve memory capacity they never advertised.
6gig is the limit and we 5,1 MBP owners need to live within that constraint. It shouldn't be a huge deal since apple advertised these machines as having a max of 4gig in the first place.
A proven fact? Who has proven it? Do you have a link or does ifixit serve as proof?
In another thread (see https://forums.macrumors.com/threads/573906/), a user claims quite plausibly that he or she has actually gotten 8GB to run well in a 2008 MBP (in 64-Bit mode). I see no reason to doubt that.
I don't think this would allow for 8GB, however, I have heard that an EFI update might allow for it later. I just think it would say it in the description if it did, it's quite a big deal.
The update did get rid of the superdrive sound on Wake, but I still get the sound on Boot. I think it's a great thing that Apple even thinks about this small detail that I was always wondering about... Awesome!

They never advertised the Mac mini late and early 2009 will be able to use 8 GB and yet they do...unofficially. The early 2009 minis were able to do so after an EFI update giving support for some memory configurations. The late 2009 models are able to do this out of the box. Before the EFI update the early 2009 Mac mini's couldn't address the 8 GB properly, after about 6 GB it went bananas and causing the Mac to slow down (i.o.w. it was unstable with more then 6 GB of ram, but the Mac was able to detect it and somewhat use it). This makes the story of being able to use 6 GB in the mbp5,1 after an EFI update very plausible because the stories of both devices are the same.
You only gave screenshots showing b2 and b3 on the chips themselves. It doesn't say anything about what b2 and b3 are. You need to post something like a changelog or documentation were it shows chips with b3 resolved a bug in b2 regarding memory configurations (as in not supporting more then 6 GB). Until you do it is just mere speculation and assumption. As such you shouldn't be providing such kind of information because it might be wrong.
In the end it's just speculation and you should have stated that it is just that. The story itself is quite plausible just as the one about the EFI update, we just don't know if they are true or not. I would not dismiss both stories because of that.
The changelog for the new EFI version only states that it fixes the optical drive noise when waking from sleep and when restarting. The early 2009 Mac mini had a similar update and iirc the iMac models at that time as well. After the update the drive was quiet when waking from sleep but upon booting the Mac you can hear the drive. At boot time the drive will be/has to be initialised causing it to make some noise. I don't think you can shut it up at boot time as this initialisation is quite necessary. When waking this isn't, so you can shut it up (which the update does). This also seems to count for restarting the Mac (I can tell that this doesn't work for the early 2009 Mac mini as it's only quiet when waking). And yes, this is also speculation.
Not hearing the optical drive moaning when the Mac gets woken is quite nice, especially when you use an Airport Extreme and the bonjour functionality as this causes the Mac to wake every now and then to keep the bonjour database on the AE up to date (i.o.w. you can sleep at night without being woken by that awful noise of the optical drive).
