Intel Sandy Bridge-E Can Reach Close to 5 GHz on Air-Cooling
As Intel's Core i7 "Sandy Bridge-E" processors in the LGA2011 package inch closer to their mid-November launch, there is already hectic activity among manufacturers of related components such as motherboards, memory, and coolers. By now, a large section of the industry has engineering samples to help design and test their components. OCWorkbench was witness to one such pre-release setup on which a Core i7 "Sandy Bridge-E" (unknown model, could even be quad-core for all we know), overclocked to 4.92 GHz with a "regular" air-cooler. The chip was idling at 45°C.
Sandy Bridge-E, as we know, can be effectively overclocked by increasing its base clock (BClk). On this particular setup, the BClk was set at 120 MHz, with a multiplier value of 41X, and core voltage of 1.51V. The memory used was DDR3-2400 MHz with CAS latency of 10T. This is particularly encouraging, not just to enthusiasts on a tight budget, but also the cooling products industry in general. Core i7 "Sandy Bridge-E" retail boxes don't contain a cooling solution, and Intel has been showing off its branded closed-loop water-cooling solution (to be purchased separately) as something that's "recommended" for Core i7 "Sandy Bridge-E". This gave many an impression that you need at least closed-loop water coolers for any hope of achieving decent overclocked speeds with these chips, and that perhaps these chips are bad overclockers in general. The likes of Xigmatek, Thermalright, Noctua, and Scythe can breathe a huge sigh of relief.

Standard SB chips are rated for 1.525v max VID under stock conditions, so it's most definitely NOT CPU voltage. Perhaps when combined with other things, sure.
There's a user here that ran 1.7v and killed his chip, too. Still doesn't mean it was the volts. ;)
But, 500-$600 is not understandable for adding 2 cores and cache. Price is almost double a 4-core 2600k. Sure you pay a premium for high end, but a premium was already factored in to the 2600k price and further increased on the chipset price which will be $$$. Total cost (which goes to Intel) for CPU and Mobo will be sky high.
It will be interesting this time around though as last time 1366 was released much in advance of 1156. It's reversed this time around. I wonder if many will see the value play in 2011.
