I am using the Ninja heat sink, and everything is cool. The problems are with booting and the PCIe video card. I have tried both a Radeon X550 and a Radeon X700pro with the same results. On a cold start, most of the time it will recognize the video card. Sometimes it will boot up with the PCIe in x1 mode (instead of x16). But on a warm boot (any kind of restart), the odds are about 5 to 1 that it will not start the video card. The computer seems to be booting up (judging by the IDE activity light), but the video card never turns on the monitor.
What I have to do is turn off the computer for at least 10 full seconds, and then turn it back on. Then the video card will be initiated (at least most of the time, not always). Is anyone else seeing this behavior, or should I initiate an RMA?

Yep I was experiencing this same issue, and it's really weird since for all intents and purposes, the system is stable. But for some reason the board thinks otherwise. I solved my issue by upping my fsb voltage (MCH) by +0.1v. Haven't had any of the booting issues since then. I'm stable at 385x8 on an E6400 now with vcore at 1.33v. The board is definitely finicky, but with some patience these overclocks are insane.

Hi all, just getting back into overclocking (and Intels after a long AMD stint) and just wanted to be sure I was doing this right.
I have a DS3 with an e6300 and Patriot DDR667 memory.
So far I have not been able to get past 2.33 ghz on the cpu (@39C with Stock fan) due to what seems the memory's inability to go past 667mhz at all. (7x333 FSB with 2.0 memory multiplier).
Is there something I have missed (I did mildly increase memory voltage but that did not help) to enable higher FSB settings without increasing the memory bus speed or should I have bought either faster DDR2 or a higher multiplying Conroe?
Also I heard the Asus P5B now has unlocking ability of the cpu multiplier and also heard that Gigabyte may have this feature too (either now or in a future BIOS). My F4 BIOS allows me to pick 6x or 7x, is that normal or does this mean it is already unlocked but in the down direction only?
Thanks!

I know ya'll are hip-deep in OC'ing, but I was wondering if anyone else was having stability or other issues due to the Microsoft high-definition audio driver? I've installed WinXP twice, and both times everything runs great until I install that blasted driver. Boot times increase by about 10 fold (no joke), the system stalls or hangs at random times, I get blue screens at shut down. All kinds of crazy crap, and the one and only single change that I've made in both cases was installing that driver.
Am I all alone here? Prolly means I have a bad audio chip, huh...

Any ideas on getting this thing to work with my OCZ Gold DDR2-800?

For anybody who wants to cool their NB w/o a lot of money, zip tie a 60mm fan to the left side of the NB heatsink and have the air towards the CPU. Here's what it looks like on my mobo.
