And what do we have here at the end of the hardware ID string for the SATA controller?
The latter is used in the "fixed" B3 stepping chipsets.
#WHAT IS 2011 MAC BOOK PRO SELLING FOR WINDOWS 7#
I installed Windows 7 via Boot Camp and headed over to device manager to pull the device ID of the SATA controller: 1C01.Ĭross referencing with Intel's datasheets I found that there are two revisions of the SATA controller: 04 and 05. And it's connected to a:Īpple doesn't directly report chipset IDs under OS X. The only other bay in the new MacBook Pro is used for the optical drive. I installed an Intel SSD 510 in the lone 2.5" drive bay and it is connected via a 6Gbps port internally: Here we have the high end 15-inch MacBook Pro. Naturally Apple wouldn't comment on what chipset revision was in the 2011 MacBook Pro, so the first thing we did was check to see what SATA ports were in use on our systems. Surely that would be too soon for Apple's manufacturing partners to have received B3 stepping chipsets, built boards around them, integrated them into MacBook Pro designs and shipped them half way across the world to Apple stores all around the US. Intel promised to begin shipping fixed (B3 stepping) 6-series chipsets by the end of February.Īpple announced and started selling the 2011 MacBook Pro lineup on February 24, four days before the end of the month. Notebooks that used more than just two ports or used at least one of the 3Gbps ports would be affected and would have to be remanufactured with a fixed version of the 6-series chipset. With the 3Gbps ports not in use the bug would never show up.
If a notebook design used the 6Gbps ports exclusively, the notebook would be fine to ship using the flawed B2 stepping parts. Most notebooks only use two of the six SATA ports supported by most members of Intel's 6-series chipset family. The remaining two 6Gbps SATA ports were unaffected by the bug. The first shipping version of these chipsets (B2 stepping) was affected by an unfortunate "oversight" that could cause failure in the four 3Gbps SATA ports that branch off the chipset. Twenty eight days after Intel launched its Sandy Bridge microprocessors, it announced the stop-shipment of all 6-series Sandy Bridge chipsets.
