"ASUS P5Q Deluxe discussion".

[Runkett]

Here's my template for what settings will be stable at DDR 1199 MHz, but fail to even boot when raising the FSB & therefore ram by 1 MHz. The fact that I am totally stable at 499FSB/DDR1199 then it totally fails to even boot at 500/1200 is obviously a board/bios issue of some kind. I am quite an experienced overclocker and this type of behaviour is very strange.

I have tried every strap at every possible FSB/Ram frequency combination to no avail. 1200 + ram speed is not possible.

I know that seems to be totally oposite to what would work.. but with those settings I have had no problem booting over 1200. I was playing around with mine tonight and would not boot when i chaged from mod to light (wtf) back to mod and booting again... (still failing stress, but i may be just trying to push it too hard).

My only other differnce was more volts, but we have differnt ram and yours may melt at my 2.3v
