Just going off of another thread about TransIntl.com compared to OWC RAM.

TransIntl doesn't even show a 12GB option for anything but the 2-chip MPs, but it's priced at $428 for 12GB.

OWC prices their 12GB for the new 2010 MP at $549. Now, here is the real question. If you go to OWC and click on their "2010 MP RAM", it'll show the $549 for 12GB. BUT, if you go to the 2009 MP RAM options, it shows the same speed ram, 12GB for $457. What gives? They appear to be the same . . . 3x4GB, 1066mhz ECC . . . 2010 = $549 and 2009 = $457. I don't see it here, am I blind?

I pointed it out before in the other thread.

Someone else asked them about it and they said its "different" somehow - with no explanation as to how.

I suggest just waiting till OWC actually get a Mac Pro to test the RAM they have - chances are the prices will adjust accordingly as they figure things out properly.

That's kind of what I was thinking as well. For sboerup, similar thread was started here: RAM compatibility / pricing for 2010 4-core
 
...The 2010 MP use 1333 RAM... (typed from my win7 HP desktop:p)...

Only the higher end units use 1333. Lower end models use 1066MHz DDR3 ECC SDRAM.

I called Apple and a tech told me that the new memory is a bit faster and has better reliability. I have no idea how important this is.
 
I pointed out in the other thread that there is a one (1) character difference in the unit serial number. I don't know what the difference is, but there is something...:confused:
 
Even Apple uses several different chip manufacturers. Same with OWC and Transintl. Since this ram is not overclocked, it is very likely that you would not see any difference between these sources. Ram prices will fluctuate with the broader chip market.
 
The memory size and speed is pretty confusing, but this is a direct cut/paste from apple's site:

=====================================

Memory

Dual-processor systems
2.4GHz system: 1066MHz DDR3 ECC SDRAM
2.66GHz and 2.93GHz systems: 1333MHz DDR3 ECC SDRAM
Eight memory slots (four per processor) supporting up to 32GB of main memory using 1GB, 2GB, or 4GB DIMMs

Single-processor systems
2.8GHz and 3.2GHz systems: 1066MHz DDR3 ECC SDRAM
3.33GHz system: 1333MHz DDR3 ECC SDRAM
Four memory slots supporting up to 16GB of main memory using 1GB, 2GB, or 4GB DIMMs

=====================================

So basically, the single processor 6 core, the dual processor 12 core are the ONLY MP's that get the faster (1333Mhz) memory. The single proc 4 core and the dual proc 8 core get the slower (1066MHz) memory. To add to the confusion, the 4 core uses the older Nehalem chip and the dual proc 8 core uses the new Westmere chip.

This threw me at first as well, as I had originally ordered an 8-core dual proc assuming that since they were Westmere CPU's I'd be getting the faster mem, but am now changing to the single proc 6 core for various reasons, one of which is this.

Hope this helps.

And to make things more confusing, Crucial is offering 2 x 8GB kits for the six-core:

$1100 for 16gb? That is a steep way to go considering you can get 16GB for under $600 using 4gb modules. Then again if you need more that 16 you might not have many choices on the 6 core.

That's b/c they're 8 GB sticks. If the hex is capped at 16 GB, I'll stick with the 4 x 4, of course, but if it ends up you can use 8GB and go up to 32GB eventually, it's worth it to me to spend some more up front.

And don't forget Apple is asking over $1900 (CDN) for 4 x 4GB of RAM! Talk about steep. :eek:
