Intel and motherboard manufacturers look as if they’ve been working flat out to reduce to a minimum delivery delays on LGA 1155 motherboards equipped with the Intel 6 series B3 revision. Intel tells us that the cards would start to come on stream in low volumes as of next week.

Contacted on the subject, MSI said that deliveries should be coming from its factories as of next week for Europe, which should mean the first motherboards will appear in stores between now and mid-March.
There’s a page on MSI’s site that gives the low down on how to distinguish between a B2 motherboard and a B3 (sticker, designation, software).

ASUS has released
an official communiqué announcing that deliveries are starting again this week, which translates to another one to two weeks before they hit stores. On the same page various ways of checking the chipset revision are described, whether this be on the box, in the bios or via a dedicated piece of software.
Lastly, Gigabyte is saying that small quantities may start becoming available as of next week, with higher volumes as of mid-March. For now
only the Gigabyte 6 Series SATA Check software has been presented as providing the means to differenciate between a B2 and B3 board but other models are in any case distinct and the B3 stepping is indicated on the box.
