The ASRock H81M-ITX does support adjusting multiplier ratios for K series Haswell processors. Oddly, this works in BIOS version 1.90, but not version 2.00. My boards came with version 2.00, and I had to downgrade to 1.90.
The four-phase VRM does make a small amount of noise and gets rather hot. There are no heatsinks . . . → Read More: ASRock H81M-ITX Overclocking
After having built small cardboard cases for single computers, I tried building single cases for multiple machines. The idea is to share the power supply between four systems to reduce cost and increase packing density. Here are some pictures of two such systems I built . . . → Read More: More Cardboard Boxes
The JMicron JMB363 is a 2-port SATA + 1-port PATA controller chip often found embedded in motherboards and in low-cost add-on cards. The chip supports operating in IDE, AHCI, and RAID controller modes. Motherboard BIOSes allow choosing the operating mode, but add-on cards are stuck in RAID mode. I attempt to solve this problem by hacking the JMB363 option ROM to put the card into AHCI mode . . . → Read More: JMicron JMB363 Add-on Card AHCI mode
Gigabyte’s new UEFI BIOS is particularly well-suited for building Hackintoshes. However, many of Gigabyte’s recent motherboards, including all of the MicroATX Z77 and H77 boards, use the VIA VT2021 HD Audio codec chip, which is not well-supported. Since I’m building a Hackintosh with a GA-Z77M-D3H with VIA VT2021 chip, I decided to work around the audio issues by swapping the VT2021 with a Realtek ALC885 chip. . . . → Read More: Replacing VIA HD Audio Codec Chip
Graphics acceleration (Core Image, Quartz Extreme) for Intel HD Graphics 4000 (on Ivy Bridge processors) works in Mac OS X! Setting the AAPL,ig-platform-id device property is required to get the drivers to load. . . . → Read More: Intel HD4000 QE/CI Acceleration
Gigabyte makes several similar MicroATX motherboards with the Intel Z77 chipset:
The first two do not have manual adjustment of VCore. This is a failed attempt at trying to use the GA-Z77MX-D3H firmware to enable them. . . . → Read More: Gigabyte GA-Z77M-D3H Motherboard
