I would say $225-250 CDN, based on the current American price from Other World Computing. Their price is $95US, to which you can add another $20US for shipping. They are about the cheapest around for memory, but you do have the aggravation of having to get stuff from across the border; particularly if you get a bad piece and have to send it back.

The G4 400 model holds 256 MB DIMMS only. 4 slots.

PC133 SDRAM stick, 512MB should go for anywhere between 119 to 189, depending on brand name and quality.

149 sounds about right.

Nope, why would that have a 512 chip for the Powermac G4 400 then?

Were did you get that information?

The G4 is capable of holding 512 DIMMS, but only uses 256 MB of them. The Power Mac G4 has 4 slots, 1 GB maximum. It can not hold 2 GB -- to hold 2 GB, it would need to support 512 DIMMS, which it doesn't. Your system also has a 100 MHz system bus, and the 512 MB DIMMS are designed for 133 MHz system bus G4's, and were not around when the G4 400 was first released. The first 512 PC133 RAM chip was introduced with the 667 or 733 G4 tower. These towers were the first to have a 133 MHz system bus.

The first to hold read PC133 was the Digital Audio Powermac G4's. They started at 466MHZ.

All the G4's before this line used PC100, max of 256MB per chip. 1GIG is the very max for this machine.

Max

I've got a dual 500. I put a 512MB PC-133 RAM stick in and it works like a charm. I don't know about the others, but this machine will hold 1.5 GB of RAM. I think the 512MB of RAM cost me $165.00 CDN.

Will PC-133 work in a 100mhz system bus-based system (ie. my B&W G3 450mhz)?

Also, whats the difference between double-sided ram sticks and normal ones (aside from the obvious facts that there's chips on both sides)?

Thanks

PC-133 _may_ work in your B/W G3, but if you put in a 512 MB PC-133 RAM chip, it will either not read it at all, or read it as a 256 MB PC-100 DIMM.

Lars,

I've got 4 RAM slots; 3 are used, 1 is still open.

Then obviously your 512 MB DIMM stick in there is being read as a 256 DIMM. The 500-dual G4 cannot hold 2 GB of RAM last time I checked.

EDIT;

This model G4 can hold 4-512 MB DIMMS, but the CPU will only accept up to 1.5 GB of RAM, even if 4-512 DIMMS (2 GB) are installed. It was a logicboard issue that had problems with the CPU reading the RAM. This model G4 also had a 100 MHz system bus, so the 512 MB-PC-133 RAM is running at 100 MHz; not the specified 133 MHz it's designed for.

Lars,

I know the RAM is running at 100 and not 133 and the machine will only recognize 1.5GB of RAM, but the machine reads the 512 stick and it works fine. I just posted the info in case anyone else wanted to put 512 sticks in their machine.

Hey guys,

I'm actually running an AGP G4 400 at home with a 512 module without any issues.

Slot 1 - 64 PC100 (stock)
Slot 2 - 128 PC100
Slot 3 - 128 PC100
Slot 4 - 512 PC133

Aggghg - what a mishmash of half truths and downright wrong.

Okay here is the easy stuff

All G4s take 512s except the PCI version (Yikes motherboard with CD only - non agp) which is identical to the G3 Blue Towers ( Yosemite motherboard.
These two motherboards have a 1 gig limit with 256 limit per slot.

4 slot AGP 100 mHz Sawtooth and Gigabit motherboards take up to 1.5 gig of RAM - ideally CL2

3 slot 133 mHz bus Digital Audio/Quicksilver take up to 1.5 gig. PC133

4 Slot 167 mHz Mirror front take PC 2100 or 2700 ( for the 867 DP only ) up to 2 gig
Dual 1gHz and 1.25 Dual. take 2700 RAM only to 2 gigs.

Now the tricky part.

Most machines from the Beige G3 - Gossamer motherboard to the Gigabit boxes will do fine with double sided PC133 but not single sided. ( Only half will show )
The 133 also has to have a "backward compatible" chip on it or it may not be seen at all.

Just to make it even more difficult you can't rely on the bus speed for compatibility anymore. So PC100 single sided often won't show or shows half....confusing..you bet and we do this day in and out.
If you put some PC133 RAM in with some PC100 RAM depending on their chip design they can
a) smoke ( literally) the RAM chips
b) ditto to your motherboard.

Anyone care to even contemplate sodimms
or
CL3 versus CL2
or
why Apple changed it's RAM spec and when you update Firmware some RAM can disappear
or
Why some PC 100 222 ( CL2 ) work in later model iMacs but some don't.

etc etc etc

Your safest bet is to have someone who actually knows the in and outs of RAM install matched sets of RAM each time you upgrade.
In our case we trade out the existing RAM at full value for matched sets when the speed is the same and we encourage clients to go in discreet steps, 256 512 768 etc and each time used matched RAM.
You CAN get away with crazy matched sets..we've seen wild combos that happen to work. Can you predict it - nope.
