ASRock X99 Extreme11 Motherboard Review

We will be outlining the ASRock X99 Extreme11 motherboard's performance with the Core i7 5960X CPU at its stock frequency (3.5GHz due to forced turbo). Overclocked performance will be outlined later in the review.


By default, the ASRock X99 Extreme11 motherboard does not apply multi-core turbo (MCT) when XMP is enabled. We had to manually apply the MCT setting in ASRock's UEFI, which is a very simple process. This will be displayed as our ‘stock' setting.

ASRock sneakily applies a 1.25V DRAM voltage when our memory is manually set to 2666MHz. This is 50mV higher than the 2666MHz XMP mode set by G.Skill.

Compared X99 Motherboards:

Memory support issues with earlier motherboard BIOSes means that there are still differences in the tests kits and configurations used. G.Skill's 2666MHz Ripjaws4 kit has stabilised our test system and will be standard from this review onwards.
