ECC memory on AGP PowerMac G5?

[B S Magnet]

I see...

And you are right, I haven't dealt with a DLSD yet, I will pick one (hopefully) tomorrow, but since I intend to max it out right from the start, I thought it would be a good idea to come here and ask about options...

Since you have experience with this kind of thing, If I remove the internal Wi-Fi module but plug a cardbus wifi card, I will still have wifi, right? not using the internal card shouldn't improve things drastically since I don't think it consumes much power or generates heat, but every little improvement is appreciated...

Yes. But you needn’t do anything drastic like take out the internal module.

You can use an 802.11n USB adapter or a cardbus wifi card and do so while the internal AirPort module is active. Neither add-on path will max out their respective bus capabilities (480Mbps and starting at around 330Mbps and up, respectively), since all these add-ons are going to be 300Mbps variations of the 802.11n standard (typically, two antennae). If you run two wifi cards at the same time on a PowerBook G4 15 or 17 (DLSD or not), all you need to do is to set the service order under the Networking preference pane.

Ah yes, rabidz7 once again, making up Mac things on the internet.

Perphaps this is the correct thread to post and ask this, but as a quad owner, I investigated to see which memory is compatible with the memory controller (no idea if it's the same on earlier G5 models...) and I believe I may have reached a conclusion, in one hand, the IBM memory controller PDF says that ECC registered memory is supported, but what isn't supported (according to users here) is buffered memory, in theory, you could use Registered ECC as long as it isn't buffered, but don't take my word for granted..

That link has a 8gb ECC ddr2 pc2-4200 registered stick, it's expensive yes, but what we don't know ifsaid memory is also buffered or not, if it isn't buffered and someone here have access to it, it could be interesting to see if a G5 supports it, if it does, the premise of a 64gb ECC G5 may be doable, if it isn't, there is another option I found:

There are other options in that publication, but note that they don't specify if it's buffered or not, yes, its ecc registered, but the IBM PDF says registered its supported... Maybe it works or maybe it doesn't...

I guess PC4200R is registered buffered memory and it definitely does not work. I have just tried it myself with 2x4GB unbuffered PC4200R sticks and it's a no go. I might have a go with PC4200P, but I guess what we need is low-density PC4200E or PC4200U or above but 4Gb sticks of this type of very onerous.

Powermac G5 Quad Ram

Hi guys, I was searching for ram for my upcoming Quad g5, and found a guy selling Kingston 4x KTM3211/1G sticks, they say it's specific for lenovo/ibm, but the specs seem to be the same as the ones for the powermac according to everymac.com How finicky is the G5 with Ram? My G4 accept kingston...

Sorry to post here , but From my experience with Mac's (PM), they only see as much ram as they want to see... like on a G4 , I had problems seeing the full module,(probably because of single/duble side) , in the SDR , it seen half the module (like 256 instead of 512 or 512 instead of 1gb SDR). , same on some ibooks, I could only max out those old systems to the bios specification , so 1x512 module , 1 empty space and rest 256's or so.... even the G4 MDD did the same with DDR2700(333's).... or whatever max was (I forgot).

There were unbuffered unregistered 500mhz 2gb modules wayback then for PC's but I don't think the PowerMac G5 could handle it .

I was thinking maybe we can solder a set of modules to see if 8 gb barrier can be passed? (but I am highly doubtful). Software/firmware limits ....

I tried ECC DDR1 over 1 gb modules , and mac(PM) G5 refused to boot... and I am remembering something like it refused to see if I mixed them with normal modules.(first x2 had to be normal one's) I used Kingmax bluechip ... modules... new.... *had no issues , but limited to 1gb 400Mhz PC3200/module...

I don't have any DDR2 PM G5's , so I can't test any of that. (upgraded internal module on a G4 lamp , but it sees only half the module not the full 1gb)

So I guess we are limited by the machine's stubbornness to see what it want's regarding ram.

*BTW I have some old server sticks (above 1gb) I can photo them , not such a big expert , because G5 refused the ram (2 x 1&2 slot) I did not press more than the above mentioned -post/boot tests.
