Help OCing mobile chip on Shuttle mobo

[ThePiston]

I have an AXP mobile 2600+ (2.0Ghz) that I just got to hit 2500Ghz on a Shuttle AN35A Ultra. I had to bump the core from 1.575 for 2400Ghz to 1.65 for 2500Ghz, but she seems stable. Right now I'm at 12.5X200. I'd like to OC the bus, but my BIOS jumps from 200 straight to 234/235/236 etc. I tried to back down multiplier and then do the bus, but if I change bus to 234 and hit enter, it shows 133.

Anyone know how to get it to go past 200?

Should I bump up the volts to the ram or AGP or do I only need to do that when I'm OCing the bus?

leave the AGP volts alone... I'm not sure what you mean by it jumping to 234, that strikes me as odd.... maybe bump the VDimm, but 2.5 is pretty respectable

What are the timings on the RAM? Is it generic or name-brand?

There is a setting in the bios that will let you adjust the bus in 1fsb increments, I don't have my shuttle hooked up right now or I would tell you exactly where it is. I want to say it's on the main page and you have to change it to expert or manual I'm just not sure. Look around it's not to hard to find. I think it might be the same tab that you see your 234/235/236 numbers and in there change that to manual or expert?

Nice overclock by the way sounds like you have a real sweet mobile, hitting 2500 on 1.65volts, is it prime stable at that voltage? What cooler are you using?

I'm using a pretty cheap HS/F. I just had it shutdown my HL2 timedemo, but it didn't lock up the system. I'm at 1.675 volts and only 42-43 C. These things rule, no doubt. I'm blowing past the Sandra CPU benchmarks for Opteron 148.
