The first ASRock motherboard with this feature is the Fatal1ty H87 Performance, but Non-Z OC will be implemented on all of the firm's H87 and B85 models. That's the plan, anyway. ASRock concedes that, because Non-Z OC is dependent on Intel CPUs, chipsets, and firmware, its future availability can't be guaranteed. Intel could probably close whatever loophole ASRock has found.
