Thanks, can you get me either an iron or iojones dump?

Same issue. If you add a UseMemDetect=No flag in your boot config it will remedy it.

I tried with the latest Chameleon build and the problem does not exist. It is unique to Chimera.

I'm using the following hardware GA-Z97X-UD7-TH - i7 4790K - GeForce GTX 770 and not seeing this bug. But I'm using a MacPro3,1 smbios.

I added this flag as you said and actually fixed the issue. But will this flag affect my system stability?

Using a MacPro3,1 ID as well. Z77X-UD5H 3770k with XMP Profile 1 with 1600Mhz RAM

I haven't fixed this bug yet but in the mean time use the following Boot.plist option:


With this option you will now see the correct RAM speed but no vendor info. Without it you will see O MHz but RAM vendor info.

Would like to report I'm having the same exact issue also

I'm having the same issue with Chimera v4.1.0/ iMac 14.2 smbios
Hardware: AsRock Fatal1ty Z87 Killer - i5 4690K - G Skill 8GB 1600 MHz



EDIT: Using <key>UseMemDetect</key> <string>No</string> does fix the issue.

I have the same problem with a Gigabyte GA-Z77-DS3H rev1.1 motherboard and 4x 8 GB Kingston 1600MHz (32 GB total)
Tested with MultiBeast 7.5 and Yosemite 10.10.5

I went for `UseMemDetect=No` boot flag
