Apple releases new... everything
iindigo:
It'll probably become a little more common now that the Mac Pros use it and thus will be a bit more demand for it.

I found 1066MHz DDR3s' quite easily.
The problem is ECC - right now, it seems to only be available in 1066. I've searched at several memory specialist places, including where we order from at work, and the 1066MHz DDR3s' at this point seem to be the only ones that offer an ECC version.
Also have to realize, the new xeons were just released what? in January I think, so there really was no need for ECC ram until they were released. And just like when the DDR3's first came out, it was a bear to find certain modules until it became more wide spread (I was a fairly early adopter with my motherboard, as it was one of the first that would take DDR3's (Asus P5K3 Deluxe - well it was the first that Asus offered at the time) - there was almost no selection, and the 2 gigs I got cost me about $200 for 1333MHz...

Crucial has 2GB, DDR3 1333, ECC DIMMS for $63(3 for $189), Registered for $105. But you don't need registered memory for the Mac Pro. So yes you can get better memory for your Mac Pro, and cheaper as well. Apple seems to charge $120 per 2GB dimm.

LMAO "1066MHz DDR3"
even with ECC they are still overpriced
my mushkin DDR2's are running at 1066MHz AND have lower latency

Remember, the new mac's are i7 based xeons, which means they (at this point since i7 only supports...) have to use DDR3 ram. Xeon systems tend to require ECC ram, which now really limits the selection.
After searching a bit to see if I could find ECC DDR3 ram, I was only able to find it in a 1066MHz speed. This may be due to the fact that these new xeons are so new that most memory manufacturers haven't started developing ecc chips at the higher speeds - only time will tell.
But laughing at ECC memory is a mistake, even if it isn't bleeding edge speed - let's face it when have server and high end workstations (not gaming systems) based hardware been bleeding edge in terms of speed and using xeon processors are usually limited to high end workstations used in CAD, 3D development, video work, etc. and servers - they are not the choice of gaming system builders.
And I just looked it up on the US stores (since I don't want to do canadian conversions) between MemoryX (a memory seller, and one of the very few places I could find DDR3 ECC ram, and apple...)

A $1.00 difference.
Not a huge overprice as you are claiming for the type of ram.
It's only overpriced when you compare it to DDR2 ram as DDR2 Ram currently is extremely cheap, especially non-ecc ram. Also, when looking it appears that the fastest DDR2 ECC ram is 800MHz, which is only $10 - $20 (depending on brand) cheaper then the cheapest DDR3 ECC ram (of which the DDR3 ECC ram is clocked faster)
So - it's better to compare apples to apples if you'll excuse the punn - ECC to ECC ram.
Also I should note, if it's running triple channel (which I suspect it is as the base configuration is 3gigs), it's overall throughput would probably be better then your DDR2s even if they're at a lower latency. But without benchmarks to compare triple channel DDR3 ECC @1066 vs what you have (or an ECC comparable chip) it'll be hard to know for sure.
Going just by latency - it's not a good idea as there is more to memory then just the latency - because in this case, if they are triple channel, then this system should push more data through then your dual channel 1066MHz at lower latency.

I was not laughing at ECC feature, it's the price and speed.
1066Mhz is the slowest DDR3 speed. and I wouldn't be suprised if they have fairy high latency(by DDR3 standard). yes I do know they're still quite new, but DDR3's ARE cheap. even with ECC Apple's prices are not justified, as you can see from the link below(though still much lower than Apple's ridiculous prices on FB-DIMMs)

I see you can get it direct from crucial, I usually don't order direct from the crucial - actually, I didn't know you could order direct from them. I wonder tho why I couldn't find more ecc ddr3 memory elsewhere...
