ASRock has announced its new Non-Z OC feature that will allow owners of H87 and B85 boards, the option of overclocking their unlocked 4th generation Intel Core processors. The H87 and B85 boards don't have official support for CPU overclocking.
The UEFI BIOS utility from ASRock supports the Non-Z OC feature; the company has also beefed up the voltage regulator module of its Fatal1ty H87 Performance motherboard. With eight phases of CPU power circuitry to ensure stable power delivery, users are able to make use the new BIOS feature to boost the CPU frequency of their unlocked processors. Besides the Fatal1ty H87 Performance, ASRock has stated the Non-Z OC feature will make its way to other H87 and B85 boards.
As a disclaimer, ASRock issued the usual warnings about the dangers of CPU overclocking. They also claim that the Non-Z OC feature is tied to the Intel 8-series chipset, and its availability in the future isn't guaranteed. Hence, this points to the possibility of a bug in both H87 and B85 chipsets, allowing for CPU Ratio overclocking. ASRock seems to have just capitalized on the bug's existence to push out their Non-Z OC feature.
