newbie herewhere on newegg can I buy ram 2GB (2 x 1gb) for the new mac pro?
kingston has ram of 800 for the new macpro?
thanks in advance
I've found Trevor at CanadaRAM to be very quick to respond to emails. Their prices seem to be the best in Canada. With the $Cdn falling below par with the $US, it doesn't make sense to shop at OWC. OWC's $25 shipping charges and customs fees to Canada balance out the cost difference between OWC's RAM and CanadaRam's RAM. Can anyone vouch for the quality of their Certified RAM?
I wouldn't get 32 all at once. Photoshop only uses up to about 4GB. I'd imagine most other photo applications don't use very much either. If you're thinking that you want to expand with the intention of eventually have 32GB, start by getting 2 x 4GB sticks. Once you have those in, run your apps and monitor the system to see how much of that you're actually using. Personally (I'm a photographer, too), I'm going to buy 2 x 2GB sticks ($200) to start with a total of 6GB. I'm willing to bet that will be enough. If not, I'll get another 2x2.
Allocating Memory above 2 GB with 64-bit Processors
When you run Photoshop CS3 on a 64-bit operating system, such as Mac OS X v10.4 and later, Photoshop can access up to 8 GB of RAM. You can see the actual amount of RAM Photoshop can use in the Let Photoshop Use number when you set the Let Photoshop Use slider in the Performance preference to 100%. The RAM above the 100% used by Photoshop, which is from approximately 3 GB to 3.7 GB, can be used directly by Photoshop plug-ins (some plug-ins need large chunks of contiguous RAM), filters, and actions. If you have more than 4 GB (to 8 GB), the RAM above 4 GB is used by the operating system as a cache for the Photoshop scratch disk data. Data that previously was written directly to the hard disk by Photoshop is now cached in this high RAM before being written to the hard disk by the operating system. If you are working with files large enough to take advantage of these extra 2 GB of RAM, the RAM cache can increase performance of Photoshop.
The default RAM allocation setting in Photoshop CS3 is 70%. These settings should be optimal for most users. To get the ideal RAM allocation setting for your system, change the RAM allocation in 5% increments and watch the performance of Photoshop in the Activity Monitor. You must quit and restart Photoshop after each change to see the change take effect.
The available RAM shown in the Performance preferences has already deducted an amount that is reserved for the operating system from the total RAM in your computer. You shouldn't set the percentage of RAM to be used by Photoshop to 100% (unless you are using more than 2G of RAM) because other applications which run at the same time as Photoshop (for example, Adobe Bridge CS3) need a share of the available RAM. Some applications use more RAM than you might expect. For example, web browsers can use 20-30 MB of RAM, and music players can use 20-50 MB of RAM. Watch the Activity Monitor to view the RAM allocations on your computer.
Watch your efficiency indicator while you work in Photoshop to determine the amount of RAM you'll need to keep your images in RAM. The efficiency indicator is available from the pop-up menu on the status bar of your image or from the Palette Options on the Info Palette pop-up menu. When the efficiency indicator goes below 95-100%, you are using the scratch disk. If the efficiency is around 60%, you'll see a large performance increase by changing your RAM allocation or adding RAM.
I have nothing against CanadaRam, but they're not cheaper than OWC for someone in Canada, although it is close. I ordered OWC's 4x2GB ram kit at US$399 which came to CDN$463 including exchange, insurance, shipping, GST, and FedEx charge for COD (to collect the GST).
CanadaRam offers an equivalent 4x2GB ram kit at CDN$458, free shipping, but you need to add GST for a total of CDN$481.
At the time I ordered, OWC indicated shipping in 2 days, CanadaRam 1 to 4 weeks. In practice it took OWC 6 days to ship, but was delivered by FedEx in less than 18 hours! In the end I could have lived with the $30 difference, but the shipping times plus the cost difference made it OWC for me.
At present (and I've been looking every day) only Kingston has the memory and has it in stock. And their price is insane.
Current sources:
- OWC / MacSales: Has it for sale, but as of last I heard, they don't actually have any in stock yet...so it's a bit misleading that they are selling it already

- Kingston: Has it in stock and for sale, but extremely pricey.
- Crucial: Will eventually have it (they have the microchips for unbuffered DIMMs, they just need to ramp up production of Apple-style heatsinks on Fully Buiffered versions...expect a 2-4 weeks and we should hopefully have stuff from them).
- Newegg: I've always bought Mac Pro memory from there, but they don't have the new 800MHz mem in stock yet, probably because no one is making it yet...
- Transcend (one of the manufacturers Newegg caries for Mac Pro memory): Not even listing the new 2008 mac pro in their search system yet.
- Hyundai/Hynix: The official source for Apple (based on someone who checked in another thread), but they don't sell consumer level and I can't find anyone that sells their memory. Looks like they only sell to OEMs.

Edit - Kingston has their memory on sale if you actually go to details - but it is still much pricier than OWC's:
