Some of you waiting for Intel P45 might consider this article rather interesting. After spending some time talking in depth to a couple of MSI's P45 engineers and Tony Leach from OCZ Technology, the guys over at bit-tech.net reported that Intel P45 motherboards will be more complex for overclocking than current mainstream motherboards. With Intel P45 you'll need to spend extra time learning how to fine tweak settings like GTL Reference Voltages, CPU VTT and its relation to GTLs, Clock Skews, CPU PLL Voltages typically available only in current high-end X48 chipsets.
Overclocking Intel's P45 is said to be more complex than it has been on previous boards - you're going to need to do a lot of specialist fine tuning. After spending time today talking in depth to a couple of MSI's P45 engineers and considerably more to Tony Leach from OCZ Technology, who spends a lot of time QAing BIOSes for companies like Asus, DFI and MSI, it looks like overclocking is going to become an increasingly more complicated art with the release of Intel's P45 chipset, as it mirrors many of the tweaks the current high-end X48 chipset offers.

if it allows for greater clocks and stability, I say go for it - It's also nice to see that the P45 is becoming as recognised as the X48 for high-end status.

With my DFI x38 I have to learn how to do all that already. It takes a shit ton of time to try and get the exact GTL's because if you dont, the overclock is completely unstable. I couldnt even run word without getting a BSOD. I will say that for some lower to mid range overclocks, you dont have to mess with GTL's. At least I didnt. Im at 3.5GHz from 2.66Ghz 14hr prime stable. At 3.6 is where I have to start messing with GTL's.

This guy and myself over on DFI-Club were trying to get stable at different speeds and he spent more than two weeks and go no where with it. Pretty damn sad if you ask me. At this point, you might as well go back to overclocking with the DIP switches on the motherboard.

Here is my thread over there.

lol most of those feature are already on current boards, and things like clock skew will sound familiar to those who oced the pentium 2 line of cpu's.

Plus, these are still a little while from production right, so the final product may be a tad different. And it seems to matter greatly what brand you have. My gigabyte p35 will do all voltages and timings and everything automatically if I want it to, while the DFI p35s apparently have many more options that must all be set manually for fine-tuning.

I would imagine the various vendors of the p45 will be the determining factor in how hard it is to oc, as is with the current situation.
