MacPro + ATI Radeon X1900 XT 512MB = 7-10 days = new card soon?
I know the MacPro just had an update
But why when you do a build your own MacPro does the ship date go up so much on the x1900 ? Is Apple just behind on shipments?
Something new on the way for 10.5? // WWDC ?
Should I order now? what do you think?

It;s been a long wait
I would like to mention that this machine smokes I went from a Mac Mini 1.6 to a Mac Pro Dual 2.66 w/ 3 gigs of ram.
I hope you enjoy yours as much as I am.
my mac pro arrived 1 day early!!! fedex said it was due to deliver on the 15th but when I woke up this morning it said it was on the fedex truck for delivery!

BAH. And mine got delayed for a day, the delivery date has moved from tomorrow to Thursday. You stole a day from me!
I am quite impatient at this point, like I said, this will be my first Mac of any kind and I'm itching to do video/PS and even gaming on it since it will be faster than my 3+ year old PC. HURRY UP.

You're adding two 1GB memory sticks to your standard 2 X 512 memory sticks?

Yep, on the second riser card, why would that possibly be a problem?

I don't know that there would be a problem, but I keep hearing people talk about "matched sets" and "256 addressing". I see this on ram memory websites and even offers for them to buy your 2 X 512MB when you upgrade to 1G or 2G sets. Just throwing out the question because I'm not sure and would like to get some responses from more knowledgeable ram people. Inquiring minds want to know.

Oh, I see. No, it means you need matched pairs in each bank of two slots. If you are buying 1GB, you need 2x512MB chips, 2GB you need 2x1GB chips, 4GB you need 2x2GB chips. Each bank doesn't have to match each other however, the 2x512MB chips that come installed will play just fine with another bank of 2x1GB chips installed on the other riser. Did that make sense?

Yes it does. Thanks.

It could be that they are trying correct the flaw in was introduced in April. Any recently ordered Mac Pro with an X1900XT does not work reliably with Bootcamp.
So if you need Bootcamp I would hold off on ordering for a bit.

At minimum, you need matched pairs. If you have a set of four identical sized memory cards (4x1GB, 4x 512MB, 4x2GB, etc), supposedly the Mac Pro runs in quad channel mode. Matched pairs means dual channel mode.
I really haven't seen a test show that quad channel mode makes a significant difference, but I'm not sure if any tests were properly done to narrow this down either.

Not saying it's so, but here's what Ramjet says:
http://www.ramjet.com/macpro.asp
The Mac Pro uses a memory type called an FB-DIMM (Fully Buffered - Dual Inline Memory Module). Ramjet FB-DIMMs work in all Mac Pro models including the 8-core. There are eight (8) slots, and the FB-DIMMs must be installed in pairs (2x identical) or quads (4x identical). Matched Quads run 5-10% faster, because the memory controller is able to address all four FB-DIMMs as a single 256bit memory bank. The original 1Gig is installed as a pair of two 512mb FB-DIMMs. The system maximum is 32Gigs with the installation of eight (8) 4Gig FB-DIMMs (two 16Gig quads).
