Not many people recommend 120 pcie clock. Use 100 for the everyday overclock ;)Quote:

I tried 355 FSB and it hangs while loading XP
Give 8x401 a go
using wat settings ?
vcore, ram voltage, nb vcore?
vcore 1.35/1.45 should do. Ram 2.0 or 2.1v and auto for the rest to start with. Mem timings 4-4-4-12 or set by spd.
Does the P5B-D have a working crash recovery like other Asus boards? You know when you choose too aggressive an OC at reboot it says Overclocking failed press F1 to enter setup.
It doesn't seen to work on my P5B-D, I've had to clear CMOS every time I hang the board up
BIOS 0614

just switch off your PSU and switch it back on
I haven't had to clear the CMOS yet :)Quote:

• Due to the chipset behavior, AC power off is required to enable C.P.R. function. You must turn off and on the power supply or unplug and plug the power cord before reboot the system.
Humm.. turning off the PSU's switch has worked a few times not all the time thow, but after 520fsb it never seems to kick in. Clear CMOS is the only thing that gets me back in the action.Quote:

Anyone who got hold of a P5B Deluxe with P965 C2-stepping?
Another question: My good old P5WD2 Premium had the restart problem where the board would completely switch off on a windows restart and then switches back on after a few seconds. This happened from FSB 243 and upwards.
I heard the P5B shows this behavior even on a cold boot when overclocked. Is that true or is this limited to warm restarts?
Set manually dram speed to whatever but not Auto ( leave it below 800)Quote:

sorry to be rude. just want to understand more
where are those new 2 bioses?708 and 709
706 works for me perfectly :D
I think it was Anandtech who reported that 708 is beta and 709 will be the official for crossfire support.
You need more vcore. try 1.5V... 1.55V if you really want to have fun. and 1.6V if you want to live dangerously. I run 1.575 24/7 on water. 1.675 for benching.Quote:

I then went for 351,352,253 (reboots in windows after 5 seconds)
Tried 401,402,403 (no change in settings except fsb and its hangs while i saved the settings in bios - restarts manually NO POST, just black screen)
Shoot straight for 405 fsb ..it should work ..
I also have a P5B Dlx here for testing and it doesnt post anywear in 360-400fsb..
wat about the vcore settings, ram timings, etc ?Quote:

No luck. Black screen. Hangs while i tried saving the settings (405FSB) in bios
Try to figure out your Ram's Max FSB it can reached by setting the ram Vdim to 2.4 and use a divder while adjust the FSB higher.
