Problems when booting any OS

[e_lion_1]

I've been off having an adventure with this RDX200 board I picked up. However, I can't seem to boot into WinXP or LFS when overclocked - I honestly don't understand why or what to change. Memtest passes with flying colors. Also, the CPU and RAM had been in my NF4 board OC'd with minimal problems.

 

Any ideas?

You say, "can't seem to boot into when overclocked." So...when at stock all is OK? What have you done since swapping boards?

[e_lion_1]

yes, ponderingpete, the setup runs just fine at stock speeds. Rig #2 was a new build from scratch using some parts I had around (CPU, RAM, Powersupply) and new parts (RDX200, hard drive, video card). To be more exact, the OS starts booting up but then dies a few seconds into it, rebooting the computer in the process.

So, after some searching, I discovered that most of the Winchesters in the overclocking database were running the ram on dividers...gave it a try and presto! everything works. My guess is that the memory controller on this cpu just doesn't like to be pushed too hard (esp. with the RDX200 board).

 

Should anybody else have some thoughts, I'd like to hear them.

 

Thanks!
