1333 DDR3 memory in 8 core westmere

would you go with 2 of 8 gig from Certified 61769x4
or
6 of 4 gig from Kingston KTA-MP1333/4Gx8
that would make it 16 gig VS 24 gig at start for the same price
Thank you

Definitely 6*4GB. Much better value and you end up with much more speed.
 
Does it have any use to buy DDR3 ECC 1333MHz PC3-10600 instead of DDR3 ECC 1066MHz PC3-8500 for the 8-core Westmere? First type is faster, but I presume, 8-core Westmere won't benefit from it?

Thats possible
but when I upgrade to twin 6 core, I wouldn't have to change memory anymore
 
My 8-core Westmere does not run the 1333 MHz. The firmware does not support anything beyond 1066. I'd be interested to know if there is firmware upgrade that I missed.

This is interesting
as Apple manual for 8 core westmere says 1333 memory to be used

Westmere or Nehalem? Cause your sig says Nehalem and the firmware in the new 8 core definitely is capable of 1333.
 
OK
I'm about to pull the trigger
yes for 1333 or no
need to know as I will be ordering it from OWC and not sure about it
as I need to import it to Canada
THX
 
its so easy to say yes it will work
The manual says it will, people selling it recommend 1066
but the manual says 1333
so i'm a bit confused
 
I'm looking to get set of those
Any recommendations other than what i'm looking at??

Kingston KTA-MP1333/4Gx8 $ 686

Certified 617684/4Gx8 $ 475

Well, if you don't want to upgrade your processors to hex cores, take the cheaper 1066MHz RAM. Otherwise, buy the 1333MHz dimms. Simple as that.

Have you looked at OWC RAM?
Definitely cheaper than the two sets you picked and 100% supported in the Mac Pro.
I'd recommend 6x4GB 1333MHz dimms, which costs you $435 at OWC.
 
1333 mem WILL work in your MP and it's about the same price as the slower mem. 1333 gives you more options in terms of upgrading the processor or transferring the RAM to a newer computer.

I can vouch personally for 1333 RAM working in an 8-core Mac that likes 1066. Of course, the Mac will only run it at 1066, but it hasn't caused any compatibility issues for me. I'm currently running 2x4GB(1333MHz) and 6x1GB(1066MHz). I think the more pressing issue concerning RAM is buying high quality modules that are fully compliant with Apple specs. In my experience, trying to save a few bucks by taking a chance with low quality or an unknown brand is rarely worth it.

That said, I didn't intentionally buy 1333 RAM for my 8-core Mac. I ordered 1066 from OWC, and they sent 1333 by accident. It went something like this when I phoned them to tell them about their mistake:

me: Hello, I ordered 1066MHz RAM for my Mac Pro, but you guys sent me 1333MHz. I know it will work fine, but I just want to confirm before installing, because I plan on ordering more of the 1066 RAM from you guys in the future, and want to make sure there will be no compatibility issues when I do that.
OWC: Our records clearly show that you ordered 1066, and we sent you 1066.
me: That's fine, but the chips you sent me are labeled 1333MHz.
OWC: Our records show that we sent you 1066MHz chips.
me: Ok. *click*


My time is too valuable to waste arguing about something that doesn't really matter, and that conversation wasn't going anywhere. But, yes, 1333MHz will work fine, even mixed with 1066 chips :)
 
This question is actually answered in the Mac Pro manual quite clearly.
All installed UDIMMs must meet these specifications:
  • PC3-10600E, 1333 MHz, DDR3 SDRAM UDIMMs
  • Error-correcting code (ECC)
  • 72-bit wide, 240-pin ECC modules
  • 36 ICs maximum Per ECC UDIMM
Note: Although the memory speed of the UDIMMS is 1333 MHz, they will operate at 1066 MHz or 1333 MHz depending on the processor in the computer.

1333 works just fine
Wow
going up in ram really speeds up your mac
That is impressive
running at 20 gig for now
waiting for 8 gig chips to drop in price so I can go to 48

the above monitor is tiny 8 inch and has a dvi input. If I place a mac pro in a small space to do server duty this size would be handy. has anyone used it?

Although I'm not exactly sure what this has to do with the thread, you should visit MiMo monitors. Cheaper than the one you listed and USB based. The USB throughput suffices for 800x600 and you don't waste a DVI port on your machine.
