INTEL Sandy Bridge - NO FSB OC?!?!

[pxc]

This I think we can thank AMD for.

Partially. There was a time when all CPUs that used changeable multipliers were unlocked. Then both companies locked the multipliers at around the same time (Intel did it first), and later offered premium-priced unlocked multiplier CPUs. The multipliers were locked to foil remarkers and dishonest system sellers. A casualty of that were enthusiasts.

My Pentium 75MHz from around 1994 or 1995 was unlocked, for example (only 3x or 4x, but still). It's nothing new.

it will have it.. intel would be stupid not to support it. the reason the 1155 socket has such limited overclocking is due to the on-chip IGP. because overclocking the processor with the FSB(bclk) would cause the IGP to overclock at the same time. the E series(socket 2011) will NOT have an IGP. so there will not and should not be a limitation to overclocking the processor.

Unless you have something to back that up, I'll file it under ocellaris's "we want it so it will have it" theory.

I've seen nothing that indicated base clock will be adjustable on Socket 2011 (anymore than it is on 1155). Where did you hear that?

During Q4 2011 Intel is expected to launch the LGA2011 platform. Dedicated for extreme enthusiaster and workstations there is support for octo-core Sandy Bridge processors without integrated graphics circuits. Instead Intel has chosen to integrated the BCLK generator into the processor and at the same time give users the possibility to, through dividers, separate the frequencies of the clock generator toward different parts of the system. In other words, overclocking with the Intel X68 chipset and enthusiast version of Sandy Bridge will work more or less just like the LGA1366 platform and Intel X58 chipset.

I see those are talking about X68 - wonder if the same news applies now that it is X79? Here's a quote from Semiaccurate's (yes, yes, I know...) X79 preview:

However, one thing that stands out is the overclocking support where Intel has worded things very carefully “Chipset support Performance Over Clocking in processor – Processor Core & Memory”. This is suggesting that Intel does not allow for BClck/QPI/bus overclocking of any kind. If this really is the case, then it’s hard to see this platform gaining much popularity with enthusiast users, no matter how much Intel is trying to push it

Everything I have heard from our Overclockers.com review staff indicates that SBe will allow for base clock overclocking (or something to that effect anyway).
