Why didn't the DDR2 RAM fit?

[eclipse]

The gap bit in the middle of the RAM stick I just bought for my Mac Pro 8 Core (2008) didn't fit where the ridge/clip was on the RISA card. The bridge/arc bit in the middle was about 3 or 4 mil too far to the right. The new DDR2 RAM wouldn't go in.

I took the cards back for a refund, and the guy from Dick Smith (Australian electronics company) said that my original cards must be DDR1 cards.

But is this true? On the "about this Mac" page the Mac Pro 8 core (2008) is calling them DDR2.

Anyone know what's happening? How do I tell what to order? Cheers.

Also, would these be any good? They seem to have the wrong Mhz... my machine is 800Mhz.

They are DDR2 FB-DIMMs, rather than standard DDR2 DIMMs

Yeah, I think you've got it.

This was the RAM I bought (and returned)... NO FB!

So I've just ordered this from Harris tech, which is FB and is good (for down-under anyway).

Don't buy RAM from anybody called Dick.

Always tell your vendor the make and model of the computer you want your memory to fit before you buy it, so they can double check you are getting the right stuff.
The conversation would then go: "Why would he let them sell DDR2 RAM that wasn't fully buffered for a Mac Pro? Then they said he must need DDR1?"
"I guess he didn't know Dick."

But seriously, Kingston RAM is top notch, good choice.

I went for this RAM though and they delivered it to Blighty: http://www.memoryamerica.com/2fk225672800at.html would they send to Oz? Only $221(Australian) before delivery and taxes.
The Lifetime warranty still applies to overseas customers. Here are the 4gb modules, not much more: http://www.memoryamerica.com/fk251272800a.html

Nice find, and even with shipping I'd still save heaps. Unfortunately, time is money and we've got productivity issues and customers to keep happy. Maybe next time.
