2GB DDR was never a part of the spec and therefore never made. Some companies were wanting to make it and some engineering samples were made, but it never made it to full production.
PC2-4200 in 2GB sticks is available. This is what is used in the Hi-Res models from October 2005. Whether it will be recognized is another matter. So anyone with such a model can give it a try in one of those.
The OP did not state which 1.67GHz model he has.
My post does not mention or detail anything about DDR2 ram. It is only stating a fact about DDR1 ram.
If he has the final revision 1.67ghz machine that takes ddr2 ram, it will work with one 2gb module in one slot. Will not recognize four gigs of ram, though WE ALL WISH IT WOULD.
That said,with a maxed out 1.67ghz final revision machine myself, I am amazed at how efficient and fast it really is. LOVE the machine. Still.
I am aware of that. I added that the OP failed to mention which generation 1.67GHz Powerbook he had.
Yeah, RAM challenged.
I just got a Hi-Res for $89 and am having the RAM slot problem, though the 1GB stick in the bottom slot is working right now, the 512M stick isn't recognized in the upper slot. It was for several days, then today it froze up, I reseated it and it isn't recognized but the machine has been working okay.
I have a January 2005 1.67GHz but it needs some work now, I think the DC in needs to be replaced. Never had a problem with the RAM since I bought it used. Maybe the owner took advantage of the free fix years back? I believe he was the only owner until I bought it in 2013. Thus I purchased this Hi-Res unit, I must say the screen is really nice.
Am I reading this right? single 2GB PC2700? Looks like the picture is different than what he's selling but it says in the description. " 2 GB PC2700 333MHZ LL2.5 MICRON MT36VDDF256724-335F3
This auction is for 1 Stick!"
Or is that a desktop memory for a server....?
You are reading that correctly, but it doesn't look like standard PC2700 memory. Look at the top corner, there are a few extra pins and on the back there is a little connector. If that is standard laptop memory, I don't think it'd work in a PowerPC Mac. It would appear to be high density with that many ram chips on it for its size. There's also the sticker reading "128MB" on the stick itself. Lastly, there doesn't seem to be much information on the part number in the listing. The HP number of 012795-001 shows the image to be an image of a 128MB cache module, probably for a RAID setup. The seller also posted a similar auction for a lot of 49 of those: http://www.ebay.com/itm/2-GB-PC2700...D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
