Nehalem, much less about gaming performance?

No overclocking for regular Nehalems after all?

... Nehalem clock frequency is determined by 133MHz reference clock frequency * multiplier.

It's not ok to increase that reference clock since other systems are synchronized with that clock frequency and multipliers are locked upwards on regular Core i7-processors. Turbo mode works on regular models and can increase frequencies up 266MHz(2x133MHz). Turbo mode can be disabled from bios.

Sounds weird. There must be a way to oc any nehalem cpu, even with the locked multipliers.

Since the turbo can be disabled I'm sure there is going to be way to over-clock the Nehalem.
It's going to be more simple on the Extreme Edition which doesn't have a multiplier lock but I'm sure the overclock experts will soon after release publish an overclocking guide for the other versions.

Here what DrWho? posted also at ExtremeSystems (http://www.xtremesystems.org/forums/showpost.php?p=3242167&postcount=197)
The principal and main clock at 133Mhz can be increased, it is called "Over Clocking" ...

I spent 2 hours yesterday to make sure it can be done.
I propose that we make fun of the next guy asking this question since it is the 6th time I am answering it on Xtremesystems...

Nehalem doesn’t like more than 1.65V

Problem with memory / CPU voltage

It’s not all rosy with Nehalem. We've learned that in spite of its 4GHz+ overclocking potential on air, that there are some limitations. You simply cannot get more than 1.65V to the chip which might be a limiting factor for high end overclocking.

Its gets better as the CPU and memory voltage have to be synchronous which implies that not all DDR3 memory will run with Nehalem. At this time you can forget all DDR3 2000 modules with voltages over 1.65V as they simply won’t work on current Nehalem motherboards.

We know that Intel is aware of the issue but we don’t know can it actually fix it. Memory people most certainly won’t like it if it stays that way.

It never will

Nvidia is pushing to sell its Nforce 200 chip to the motherboard vendors but many have told us that Intel's reference design doesn't include support for Nvidia's SLI chip.

Intel wants to get the software support for SLI and Nvidia insists on selling Nforce 200 chip, as a solution for SLI. This makes things awkward for motherboard manufacturers are they are stuck in the middle of a nasty fight. The initial boards based on Intel’s X58 reference design won’t run SLI, they will run Crossfire but motherboard manufacturers seem to have X58 boards with SLI Nforce 200 chip under design.

At this time there are no plans for Nvidia to make a Nehalem chipset and it doesn’t look that Intel is eager to share its Nehalem technology with Nvidia.

1.65 vcore good grief that's crazy. Fast death.

I agree, that vcore is nuts without extreme cooling. Hopefully 4GHz will be doable with much lower voltages!
