    MP 1,1-5,1 Delidded CPUs on a 5,1 Mac Pro (2010) experiment!

    Has anyone ever tried to upgrade CPUs on a 2010-2012 5,1 Mac Pro using delidded CPUs? Reasons could be either thermal performance, recycling a pair of CPUs coming from an older 4,1 Mac Pro (the dual cpu tray needed delidded CPUs), or just for science! I tried this experiment, upgrading a 2010...

    Issues after upgrade to 2017 iMac

    Hi all Hope I am doing this right and not repeating someone else’s post. I recently upgraded my iMac 2017 21.5” with new ram, an SSD hard drive and a new CPU. I have built my own PC before but never done repairs on apple products. Long story short… the first time I booted it made the...

    Anyone done a CPU upgrade for an iMac Pro?

    Lots of questions. Did you use an Apple spec'ed replacement CPU? Did it work right away, fire up with no issues/tweaks needed? What did you have, and what did you upgrade to? Where did you get the CPU? The process is different than other iMacs, obviously, but getting into it is the same, the...

    Pushing an Early Intel Macs limit: can a mid-2011 Mac mini’s Sandy Bridge CPU be upgraded to a higher spec SB CPU?

    If we’re ever going to bring in slightly newer early Intel Macs, the Sandy Bridge Core iX series — which were sold alongside late C2D Macs — ought to be fair game. :) I’ve spent an unhealthy bit of time poring over the Intel page labelled, “Products formerly Sandy Bridge” and looking over chip...

    This is a Wiki post with information collected from the entire thread. Before you post, read this first. The difference between Mid 2011 21.5" and 27" concerning CPU upgradability is mainly caused by the available power from the power supply. --- The 21.5" has 210W power supply, the 27" has...

    Upgrade iMac 27" Late 2015 to i7-6700 (non k)

    Has anyone done this? I've read many successful upgrades to the 6700k but none for the 6700. I'm upgrading from the base i5 6500. Since the performance different is negligible as you can't overclock it, I was thinking of getting a 6700 for cheaper. I probably won't do it unless anyone confirms...

    CPU upgrade Disappointment :(

    I know there are a ton of successful 4 core to 6 core, dual processor upgrades for the 2009 MacPro on Youtube, but I'm sad to say that my attempt ended in disappointment.

    Hi, I recently went the route of trying to upgrade my Mac Pro 5,1 8-core model to the full 12 core processors, with upgraded RAM as well. At first I was reluctant to try it myself, but several colleagues had done it themselves, and said it was relatively easy to do. So like many folks, I...
