Mac Forum / General / Portable Macs / December 2004G4 iBook - Question about RAM
Hi - I just bought a new iBook (G4, 1GHz, 40GB HDD) with the minimum amount of RAM (256 MB). My question is: what is the RAM capacity of my machine? Or can I figure it myself by tinkering with it? I heard the original G4s could only hold 640 MB max, but the new ones could hold 1.2GB. Thanks... * posted via http://mymac.ws > Hi - > > I just bought a new iBook (G4, 1GHz, 40GB HDD) with the minimum > amount of RAM (256 MB). My question is: what is the RAM capacity of > my machine?

CNET's review of the first configuration of the iBook G4s said 640 MB is the max. ("The main limitation is a maximum of 640MB of RAM.") The iBook I bought is the 1GHz version, so I "think" I have the original issue G4. But I'm not sure. Is there a way I can tell by tinkering with the machine itself??? * posted via http://mymac.ws > > http://www.apple.com/ibook/specs.html > [quoted text clipped - 3 lines] > 1GHz version, so I "think" I have the original issue G4.

Where do you find information about 1GHz iBooks, whether G3 or G4? I did not see any reference to such a computer in Apple's specifications list. There is a 1MHz 12" PowerBook, but that's also specified for 1GB RAM, so it's a non-issue.

The Applespec DB only contains one listing for G4 iBooks, 1.2 and 1.3GHz. While there are 800 and 900MHz iBooks, they are G3, not G4. Where at Apple do you find references to sub-1MHz G4 iBooks?

A bit irritating, that. Thanks for the pointer; I'll have to be more thorough in my searching of Apple's site from here on out.

Apple disagrees with you: http://docs.info.apple.com/article.html?artnum=88039 Also, if you Google, you will find plenty of reviews of the 800 MHz *G4* iBook. You can also find them for sale on eBay.

The iBook I bought is the > 1GHz version, so I "think" I have the original issue G4. So far I've seen references to 800MHz and 900MHz G3 iBooks and 1.2 and 1.3GHz G4 iBooks, but none to 1GHz iBooks of any processor. There is a 12" _PowerBook_ with a 1GHZ G4 processor, but it also takes 1GB RAM. AFAICT all G4 portables (both iBook and PowerBook) support at least 1GB RAM. CNET almost certainly simply got the information wrong (and no surprise given their relative lack of focus on Apple equipment). Note that at least one user comment on the iBook claims that it can take 1.2GB RAM (but actually says 1.2MB). Note also that it is common for machines to physically accept and use more RAM than is officially listed as supported. The maximum RAM listing from Apple is either the maximum available, or the maximum tested configuration AT THE TIME OF RELEASE. If higher-capacity RAM chips become available, Apple does not revise their maximum RAM specs. HTH SignatureLater. johajohn@indianahoosiers.edu Let 'indiana' be a 'noln', and 'hoosiers' be a 'solkk'.

[URL's to specs snipped] Note: I'm not the OP, nor do I have any question about what model I own. I've got a PB 15" 1.33GHZ. I don't mean to appear huffy, just trying to make it clear what I'm doing. Text can be tricky that way, so I'll say it up front: no offence intended. :-) > earlier g3 ibooks are also listed. the only tricky part is determining > which ridiculous non-descript apple name (i.e. 'dual usb late 2001' or > 'opaque 16 vram') matches a particular model. a couple of clicks is all > it really takes to find out. Well, the models are descriptive, but not based on visual clues (you can't look at the box to know how much VRAM you've got, but you can use the System profiler to find out). I don't think we're disagreeing with each other here. > there may even be a knowledge base article > on how to determine the difference - there is for g4 towers but i have > not looked for other models. The point that I was making above is that it doesn't matter what G4 portable the OP owns: _all_ of them are spec'd at 1GB RAM or more. I was also addressing (not as clearly as I could have, I'll admit) the possibility that the OP mis-idetified the computer as an iBook when it was actually a 12" PB. I've seen this particular mis-identification happen in the past. If the OP is in fact incorrect about what range they own, looking for information will only confuse them. If the OP is correct about the range, then the OP mis-reported the speed. It's not a big deal in this case, but it can make a difference when checking specifications, as CPU is one of the first-pass ways of narrowing down which model is in question.

Cathy Signature"there's a dance or two in the old dame yet." - mehitabel C.Stevenson, M.D. cats1921@invalidsonic.net > Cool Thanks everyone. Now I have two follow-up questions: 1) Should I fill the empty slot with a 512MB or 1GB card? I don't perfom any intensive activities beyond light Photoshopping, but the "guy" in me wants the best. Will there be a big difference betwen the two? 2) Based on your experiences, what are some of the cheapest online retailers?

It's funny how pedantic posters can be. I just meant that I'm not Photoshopping often or with crazy multi-layered imaging. You're right though, just running the app can be draining. Anyhow, I bought a $159 generic 1GB stick off Outpost.com. It's a risk, but those who've used it on the Apple RAM forums seemed to be problem-free thus far... * posted via http://mymac.ws |
