Underclocking 1.4GHZ to 733 Concerns

this sounds like good news for my 1.4 ghz xbox. I got it from zzattack and I had the plan to build it up as my one and only XBOX, although in reality I don't think I could get rid of my 1.6 :).

I already have an openxenium, so I can run 2 bios versions. I should start making time for my XBOX projects again

Since you already have a Tualatin box, maybe you can be the first to report whether the FSB can be pushed higher than 150Mhz or so without lockups using the "separate clocking" method to keep the memory BELOW that. Then, once we hit a wall, we can see about finding a way to up the voltage and push it harder. This may require an external ATX supply and I will try to ask N64 freak about upping voltages with the interposer in play, since I'm SURE that some part of the SMD circuits under the CPU on the interposer deal with core voltage. With my limited knowledge of electronics, if that's the case, it may skew the results of the traditional method of overvolting the CPU; modifying the IC south of the processor.

Well now with this project stellar stuff seems like it could make messing with the clocks much easier. Think I'm going to wait and see how this 256mb of ram works and get a 1.4ghz 256mb ram box.

Yeah, I saw that. I wonder how that's even possible!?
