ASUS Maximus IV Extreme B3 Revision Review

ASUS Maximus IV Extreme B3 Revision Review


Modern technology is like the sea. There are high waves when the latest upgrades and chips are released, followed by a brief lull as we wallow in the calm before bracing for the next.

The LGA1155 release and accompanying P67 chipset was a definite wave. It was such a phenomenal performer that it would be easy to call it a tidal wave, but with the current problems in Japan we shall respect them and refrain from such metaphors.

If you’ve just come back from a six month sabbatical in a cave let’s bring you up to speed.

In January Intel released the successor to the LGA1156 socket processors, the (confusingly) named LGA1155. It was met with a clamour of deserved praise before it emerged that the number 5 and 6 SATA sockets had problems with data integrity. This was disappointing for such a long-awaited product and a smudge on Intel’s testing procedures, but they issued a swift recall and, now fixed, the P67 is reborn with the B3 suffix.

Technical Specifications

The only change besides the B3 chipset revision is the upgraded BIOS from when we last tested the Maximus IV Extreme. As the overclock was rather tame last time we’re hoping a much maturer version should lead to performance gains.
