Only a few weeks ago, many people had written Sandy Bridge off, and claimed overclocking was dead, and, well, they were wrong.  Yes, it has changed, and yes, it has become much easier, and sadly, yes, it doesn't seem to be too sub zero friendly, but I'll take the slightly diminished fun aspect along with the improved power consumption and gigantic clock speeds, thank you very much!  One big difference with Sandy Bridge, is the "locked" BCLK, I say locked, if you have been following Sandy Bridge, you may know that the entire system is synced to the BCLK, which runs at 100MHz, so if you try and tweak the BCLK too much, things like PCIe and SATA will soon start to loose their grip on stability.  This leaves us requiring CPUs with unlocked multipliers to do our overclocking business!  The great thing about having a fixed (or almost) BCLK is that you can tell right away, where your memory speed will end up, regardless of the multiplier that you use.  On previous Intel platforms, you may have bought a 1600MHz kit, and overclocked your CPU, only to find it running, annoyingly, slightly slower than you expected - that is a thing of the past with Sandy Bridge.  Set it, and forget it!Today, we are going to take a look at one of Corsair's high end Dominator GT kits, this one is rated at 2133MHz, and features 2x2GB modules running at 9-10-9-27 2T.  Not the tightest timings available, and not the highest bandwidth, but certainly not a mainstream kit either.  We know from previous experience with Dominator GT kits, that they are usually nicely binned with a decent amount of headroom for overclocking or tweaking, and that is exactly what we are going to do today.  How will they do?  Read on to find out...
