Why aren't sticks stable when you run anything but 1:1?

[lchyi]

Okay, before I had a problem overclocking to speeds I liked but thanks to ya'll, I figured out that it was the fact that I ran other ratios other than 1:1. If I run a 4:5 or a 3:5 or whatever it is (my motherboard just outputs the mhz instead of the ratios which is nice on my calculator) the system will not boot and my mobo will give me a long beep... almost always. This is of course if I set it under 130 fsb (I have a P4 1.6A ghz). So right now I have 145 on 1:1 but I mean, that's a dissapointing 290mhz for a DDR333 Hyper-X 512mb (x2). I've heard that you can crank bus speeds on this chip up to 170 and that would be nice if it didn't just poop out on me around this fsb. I can't get it past 150, let alone 170. Is this supposed to be normal or should I just drop my fsb about 20mhz and set the cpu:mem ratio higher?
Edit: my computer just beeped at me, is that a problem? (one short beep while updating a Xanga) Uh is 1.76vcore too high?

What's the pack date on your CPU? It's probably that you've just hit it's max stable clockspeed for that particular CPU especially if it's an older one because many wouldn't go beyond 2.4ghz and if that 1.76v is actual then it's too much, it's recommended that you not go beyond 1.7v actual. Also with the SC-DDR 845 chipset based boards a single stick of ram usually gives better results. What's the vDIMM voltage set to? Have the latest bios revision? Tried with just 1 stick? How are the voltages, the 12v line in particular? Do you have all 3 power connectors hooked up, if not try it.

"Do you have all 3 power connectors hooked up, if not try it. "

when you mean that, are you refering to the (2) 12v connectors on most new mobos?

With the Asus you get the ATX, the P4, and a 4 pin molex connector called EZ-Plug on the board in case your PSU doesn't have the P4 connector. Some have reported better overclocking results using all 3 power connectors at the same time.

sweet, i'll hook it up and monitor the voltages.

Hrmm when I bought my computer people were talking about good pack dates and I wasn't too interested in learning which ones were good. But here they are if anyone remembers back in the Ice Age hehe (well it was about six months ago when I built this).
