Msi845Ultra 1.6A@2.4GHz Thanks to:

😀 Msi845Ultra 1.6A@2.4GHz Thanks to: Jwyatt, KingBlve,and Nate420. Anandtech is lucky to have members like these . They provided me with invaluable information to help me get through my first overclocking project. I almost gave up out of frustration of not being able to accomplish overclocking, but their encouragement and advice kept me trying until my goal was reached. I appreciate your help you guys, thank you very much.

Jwyatt was especially helpful with his step-by-step instruction that accomplished the desired end result in a matter of minutes. 🙂 You da man!
 
Congratulations FatPat - great overclock. I'm only running 133Mhz bus so far with my 845Ultra. I agree Jwyatt's posts have been very helpful to me too.
 
Good to know some folks have one 🙂

I've got a 1.6A and an MSI 845 Ultra-ARU sitting on my bed taunting me. Doing some last minute back ups and gonna see what happens 🙂

I hope you don't fool around like I did until I got clued it. I believe Jwyatt told me to go directly to 130 fsb and increase by 5 until you get to 150 which equals 2.4GHz. Jwyatt said, "After running at 133 its all down hill from there. Take it to 140. If it boots and is stable. Take to 145. Keep going up. You probably will be able to get it to 150fsb, but might be unstable without doing a mod to the actual CPU to get more juice out of it." He was right, but so far I haven't had to do the wire trick to get 1.7v. You might try different core voltages. I had to go with 1.65v. HTH
 
Much appreciated man. Just running 1.6 right now. Gonna throw some Prime 95 at it later and go to 133. Then will test from there on out.

Do you know what PCI speed you are running? At 150 fsb are you running 38mhz or is it still at 33mhz? Just curious if it keeps in spec, or if there is a way to lock it if it doesn't.

Where/how do I find out? 😱
 
I don't think that board has any PCI/AGP lock. At the stock 100Mhz fsb, PCI would be 1/3 of fsb. So 150fsb would run PCI at 50Mhz I believe.

Whoa, it's gotta have a 1/4 divider. I've seen too many folks at 140+. Too many folks would be killing their systems otherwise. Anyone know for sure?

I don't think Sandra is accurate on the speeds.
 
Unfortunatly sandra doesnt even show the AGP or PCI speeds when you go to 133. It does show them at the 100fsb. Not sure why they cant tell us what we want to know. Anyways. At 133 it goes to 1/4PCI can 1/2 agp dividers. Same holds true all the way through. Some have said at 166 it drops back again to set the speeds to default, but my tests have shown the opposite.
