    Hi,

    I have MP1,1 upgraded with X5365s. Previously it had Xeon 5130s in it. It runs 10.9 using Tiamo's boot.efi

    The machine has occasional kernel panics, on average once a month (it runs 24x7 since 2009). The panic reports usually mention "Machine Check at ... / com.apple.driver.AppleIntelCPUPowerManagement"

    The panics started before I changed the CPU or hacked the OS. They occur without any correlation to load or running applications - i.e. I can have it running Handbrake jobs with 100% CPU utilization for couple of days without any issue and sometimes it panics being completely idle.

    When I run Apple Hardware Test, it reports "4SNS/1/40000001: VMBS" error.

    Does anyone know what this error means? I did some research and there are conflicting opinions - people mention logic board failure and say that "4SNS" means some kind of sensor.

    Thank you.

    4SNS means sensor failure/enormous read, VMBS stands for voltage memory (board?) sensor. Check memory risers voltage reads with iStat or Hardware monitor. If one will show a lot more (or less) than 12V, you have the answer.

    Post also (whole) KP log here, using

    Thank you for suggestion. I have Hardware Monitor and it shows Memory VRB Supply voltages at 11.8V both. I'm attaching the screenshot of Hardware Monitor for reference.

    Here's the full typical KP log:

    I see that you didn't flash it to 2,1. Some users experienced such KPs with 5365 and 1,1 firmware (it isn't general rule, but happens). Flashing to 2,1 was the remedy. Head over to netkas forum to DL firmware updater for 1,1.

    Unfortunately I have a rare breed of MP1,1 with firmware MP11.005D.B00 and it cannot be upgraded to 2,1.

    As I said earlier, I had these panics while running on stock 5130s, so I don't think it is caused by EFI/CPU incompatibility, although it may be the case.

    Got another kernel panic this night, when the machine was completely idle. This time with the latest firmware applied. Here it is:

    Machine check with uncorrected ECC errors point at RAM. I should have been told you this right after you've posted first log, but this VMBS AHT error has misleaded me a bit.
    Try to remove some RAM and see if issue will persist. You can also DL memtestx86 bootable ISO and test RAM using it.

    I have run memtest86 overnight and it finished without detecting any errors in the RAM.

    So, the panic error message means that the cause of the panic was some sort of RAM error / corruption ?
