Core i7 965 XE Races Through to 4.20 GHz
It's high time to break the dogma. Core i7 965 Extreme, Intel's next generation flagship desktop processor based on the Nehalem architecture, does indeed overclock satisfactorily. IT OC Taiwan overclocked the chip, which sports an unlocked FSB multiplier, to a respectable 4.20 GHz, at a FSB speed of 200 MHz, and multiplier value of 21.0xFSB. A vCore setting of 1.72 V was used, which is above the danger-mark, taking Intel's own warnings into account. The CPU was aided by dual-channel DDR3-1600 memory operating at timings of 8-7-7-24. It provided a tested bandwidth of close to 16,000 MB/s. The CPU took 3DMark Vantage for a spin, with 3596.76 plans/s in CPU Test 1, and 32.87 steps/s in Test 2. The chip used in the attempt was an engineering sample.

also what cards is it with ?
but my i965 con run 4400mhz with 1.5v with LN2, bench 3D vantage.
hope i can do better
A well overclocked Core 2 Duo based Dual or Quad core processor is a lot of bang for the buck these days and it might be 6 months or longer before Core i7 is really worth upgrading to for the enthusiast. It looks pretty pricey at the moment for what you get.
NV4 good, NV5 fail,
G80 and G92 good, G200 fail
If the i7 doesn’t OC well its more of an issue for enthusiasts (you and me) and that’s hardly a world market. Considering where AMD is now performance wise I don’t think the world is going to turn tail on Intel over OC potential.
Both seem equally enticing in my current position. I'll probably go with what's cheaper.
so they dont go boom once you get above 1.6v thats cool but are they any faster? 4.2ghz on a wolfdale is a 10sec superpi can i7 beat it?
we dont need more cores, just faster ones.....
Most of the computing world simply doesn’t care about overclocking.
I care about OCing, as I trust many here do, but I dont pretend that the rest of the world does. The business sector expects their computers to work, work hard, work fast and be reliable. OCing doesn’t even enter into the equation.
***edit***
This is also very new hardware. There may be newer revisions in short order that update the i7 core to overcome its limitations.
For example, earlier versions of the Athlon 64 processors had a limitation that dropped the memory speed when all DIMM slots were populated. Who’s to say that a Core i7 OC killer now isn’t fixed in the next stepping?
...I know it doesn't look like I do, either.
