    Hello, I am attempting to upgrade my dual CPU 2009 Mac Pro and would like to know if anyone has used the x5687 in their dual CPU Mac? I know some have tried it in a single CPU machine with no success.

    I know the 3.46 version works. Maybe I will find a vendor with a decent return policy.

    I think this would be a waste of time, it isn't supposed to work. I have seen one user on the Netkas forum try it with no success. Some have gotten the x5677 to work, others have had issues.

    Much easier to go with a 5680-90, or a 5679 which would work

    When I upgraded the last time, I wanted to put in X5687. But I searched all sources that I could think of, and could find no X5687 installations in a Mac Pro. Even Geekbench which has a very large database of CPU installations has no installations on a Mac Pro or Hackintosh. In the end I went with two X5677, they are working fine.

    Note: The X5679 is a different animal, it's a 6 core, 3.2 GHz. I assume the OP, like me, was looking for the fastest 4 core CPU available that would work in a Mac Pro. The X5677 is it.

    I think it's better to avoid this "unknown" CPU for a dual 4,1 upgrade. Otherwise, you may never know if you didn't install the heatsink correctly, or the CPU itself doesn't work.

    Thanks for info

    Hey everyone thanks for the info. I was hoping a few of you with experience would reply. I have read some of your threads in the past.

    Sounds like X5677 might be it. Should I go new if possible? I assume the stepping needs to match?

    Flowrider, are you still happy with your setup? Is there anything special I need to know about the X5677? Numbers look good.

    i think ur better off with a x5675, it turbo to 3.4ghz from a 3.06ghz and its the highest clock for a 95watt tdp.

    Just my two cents, I also installed dual x5677 processors in my 2009 and it's been great. I wanted the fastest possible clock and didn't require 12 cores. I went used off ebay, pretty cheap and no regrets.

    I read online that "there might be issues" or "memory problems," but everyone I found who actually went this route has been very pleased. I rather suspect that they're just underutilized and therefore less is known. Best of luck with your mod!

    Yes, if I had it to do over again, I'd do the same thing. I did have one small glitch. Of the first two that I got, one of them would not read RAM slot two, the vendor gladly exchanged it, and all has been fine. Nothing special about the installation on a 5,1 Mac Pro. You, of course on a 4,1, will have challenges I didn't have.

    Do you guys have any suggestions on a good vendor on eBay or elsewhere? Unless we are not allowed to ask in this forum.

    Flowrider/Lou, I assume what you mean by "challenges" is the need to modify the firmware? Sounds like your vendor was very responsive with your issue.

    If you think the challenge is the firmware, you have some reading to do.

    No, the Firmware mod is quite easy. The 2009 4,1 Dual Processor Mac Pro uses lidless CPUs. These CPUs were manufactured with no head spreader, and to install lidded CPUs (which everyone sells) you need to compensate for the added height of the lidded CPUs. There is much discussion and DIYs on this forum from folks who have tried and succeeded and well as those who have failed.

    Updating the CPUs a 4,1 DP Mac Pro is something I, personally, would not do, but as I said many have tried and most have succeeded. If you'd like, I can lead you to the DIYs. LMK.

    I hear you. I know the issues with with the lidless cpus and how some DIYers compensated for the extra height. I have built PCs in the past and I learn patience and testing goes a long way to making sure things are done right :D.

    I will take you up on your DIY links just in case you have some that I haven't visited.

    Thanks again, JD.

    Thanks Lou, I agree. I had checked this one out too. The site is informative. Whats interesting is that he states that the x5687 is a possibility and I have attempted to contact him about it, but got no reply.

    I wouldn't get too excited.

    He also states of the 3,1:

    CPUs can be upgraded to X5492 running at 3.33GHz but these are rare and costly. Reckon on $500 a pair. Not much of a speed gain over stock.

    Which is also 100% WRONGO !!!

    I wonder how many poor bastxxds have purchased incompatible CPUs as a result of this poor advice.

    The guy did everyone a HUGE favor putting that guide together. Fixing these typos would be awesome.

    just buy tried and true chips

    Unless you are getting a huge bargain on those chips, the X5670, X5680, or X5690 are tried and true chips on the 4,1 and 5,1 machines. I installed dual x5670s on my 4,1 just by following instructions from Pindelski's website, and it pretty much got me there within two hours (one hour wasted shooing away my 5 and 7 year old children).

    Is your Mac up to speed? Find out with Geekbench!

    Well, not so great for single core performance, but not too shabby for multicore performance. Really cheap and it works.

    Although, I swear that the results were closer to 27000 multicore when I first tested it in Mavericks -- and this Yosemite build is 10.10.1 -- perhaps not ready for primetime?

    Though not as popular, the X5677 certainly is Tried and True:

    For folks who don't need 12 cores, but require fast 8 cores, the X5677 is ideal.

    I agree, he did a great job on the guide. However, since I never received anything back from him on my inquiry, I figure he may not stand by those statements. Or just not interested in replying. Who knows.

    I moved on and I am looking around for some x5677s.
