    Will be grateful if another set of eyes can confirm that this 32GB set of Samsung memory will fit/work correctly in a Mac Pro early-2008 3,1 2.8GHz 8-core system. New, lifetime warranty, for $100 seems like a good deal and the seller has a good rating.

    The description includes:

    32GB ECC Fully Buffered Kit (PC2-5300, DDR2-667MHz)- (8x4 GB) For Dell PowerEdge 2900,2950, 1900, 1950, 1955, R900 Only. Major brand FBD DIMMs manufactured by Samsung

    Condition: New
    Brand: Samsung
    UPC: 0741360956902
    Capacity per Module: 4GB
    Number of Modules: 8
    Form Factor: FB-DIMM
    Bus Speed: PC2-5300 (DDR2-667)
    Memory Features: ECC Memory, Fully Buffered
    Number of Pins: 240
    Warranty: Lifetime warranty
    Certified for: Dell Poweredge 2900, 2950, 1900, 1950, 1955, R900

    Photo shows Samsung label on the memory, with part number M395T5160QZ4-CE65.

    From what I've read in the forums this looks like it should be good, but I didn't find this specific part mentioned in any threads. Would rather be sure than sorry -- thanks.

    Apparently the MacPro3,1 shipped with DDR2-800 PC2-6400 RAM, not sure if this would work, though it could.

    It will work. 667MHz works just as well with at most %4 slower. See BareFeat.

    I used Samsung ddr2 pc2-5300F FB-DIMM before. They worked beautifully. Temperature is ok. Fan stays quiet.
    Best of all, where I get them from cost only USD5 per 4GB module.
    8pcs? USD40.
    USD100 is way way too expensive.
    But they are not new though. U

    I guess something like this?

    Thanks you three for the replies.

    Looking at my OP, I should have mentioned that I'm a longtime Mac Pro user and familiar with the 667 MHz vs 800 MHz pros/cons. Also that I am acquainted with other brands/parts from non-Mac server pulls. I just hadn't seen anyone specifically mention this Samsung M395T5160QZ4-CE65 in their setups.

    I've decided to order it. I've been able to cross-reference with other parts that are known to work in the 3,1 and I'm reasoning this part will be fine.

    There are definitely cheaper buys out there, but like the $40 eBay offer mentioned above they tend to be used (how used?) and/or unspecified brand (riskier) and without warranty. I am willing to pay more for new, Samsung, lifetime warranty.:)

    I'll post again once I have them installed and evaluated.

    The USD5 per 4GB module I mentioned of is from Samsung with the exact same model number.
    Anyway, would definitely wish you to have the best outcome of your purchase!

    Just following up to mention I now have 32GB of these installed and all seems well.

    I just put in 32 GB as well of the same RAM, so far so good. Can get these Samsung dimms for ~$40 for 32 GB on eBay, pretty cheap!
