Dude 500FSB is REALLY hard on a lot of chips and motherboards. Don't ever buy a chip because you expect to get 500 FSB lol... that's silly!
u've been missing out, go to the UD3P OCing guide on the mobo page
my last board (P5Q Pro) was rock solid @ 492

Not anymore. The Gigabyte UD3 series is doing 500+ FSB with quads. Robilar is running a 612 FSB with a wolfdale and his NB temp is 35°C with the stock heatsink:

Here is Robilar's thread with links to XS:

I wanted to get to cold benching this weekend, but have the flu, so that might need to wait til next week unless I can at least muster enough energy to drop the single stage on it. Picking up DI or LN2 tomorrow isn't likely at this point, but I'll post results when I get them.

DDR2-1400:

Here is a quad core at 500 FSB

Closest stable was 490x9 with the MIIF. I've only had 1 BSOD with this board and it only took an hour for the beginnings of an oustanding OC session.
This is what i call FUN! I've booted into windows at 533X8 only to get my 1 and only BSOD after 10-15 seconds.
That was with no extra voltage over what i'm running now. I'll be checking for max FSB Next.

Thanks to napalm for some bios settings.

some guy on XS had his Q6600 OC'ed to 515 x7, not sure if it's stable.
maybe i should see how much FSB I can OC before i ditch my Q6600

I think Q9450 will get you 3.4-3.6GHz for sure while Q9550 will get you 3.6-3.8GHz guaranteed. Most of 'em OC above average though. The Q9550 C1 in my sig rig was 4.0GHhz stable on my P5Q Deluxe. I also got a UD3P that I'm installing today!!
At long last...

500 FSB is doable, it's just that you need a good motherboard! My POS 750i FTW isn't helping!!!

So today the mobo came, I bought a Q9500 C1 (i know) for just less than 250 US.

The Gigabyte p45 UD3 boards are that good, would it help my oc better than my p35 ds3l?
post #30 of 35
The motherboard may be up to it, but the problem is that many of the yorkfields have FSB walls. I have had more than several and unfortunately the highest wall I had was about 485mhz on a Q9650.

My motherboard is certainly up to it as I have a P5Q deluxe and have booted at 620fsb before and can easily get over 500fsb 100% stable on a dual core as they usually don't have the FSB walls quite as low as the yorkfields. (also can get most Kentsfields 500x8 stable)

So basically it just depends on your luck with the chip, which is why if I had monies, I would get the highest multi possible
