P4B266 & 1.8A Northwood Settings Questions

I have the P4B266 with on board audio and USB 2.0, a P4 1.8A Northwood, and 512mb PC2100 Crucial. I cannot get it to do 2.4, I think, due to some of the bios settings. When I set the FSB in the Bios to 133, memory at 1:1, it will not boot, no matter what I set the voltage too. This also happens when I have the Option set to Normal, Turbo 1 or Turbo 2. When I use the dip switches to set the FSB at 133, it boots right up and makes it to the start of Win XP loading, then freezes up. I think I would be fine if I could up the voltage when using the dip switches. I have it set right now at FSB 125 via the dip switches and it is running perfect at default voltage. I upped the voltage to the memory to 2.7v but that has not made any difference. Any idea why it won't work doing the settings in the bios?
 
I have the same difficulty in getting into 133 FSB, I can at most get to 120, I can't boot up to Win2k when i try 121 (and the machine won't post for 133 like what u experienced)...I've also tried upping the voltage for Vcore and DDRRAM, it didn't help either.


P.S. My cpu is 2.0A


 
I have that same combo and it wouldn't O/C to 2.4 until a couple days after. Maybe burn it in for a few days. If not using Arctic Silver use that too.
 
I did take the retail heatsink and removed the metal heat transfer, or whatever you want to call it. I put in Arctic Silver, but nothing changed yet. I have a Sunflower on order, so maybe when it arrives I can get there.
 
I'm using AS2 and P4 volcano HSF. I tried pushing the FSB to 133 after a week of "burn in" period, but it doens't help. I guess i had a bad start for my first o/c experience
 
Do you have any USB devices such as mouse and keyboard connect to USB 1.1?
If so, move them to USB 2.0. That will take care of the problem.
 
I got the AVS Sunflower and installed it. No change. Next I guess I will try the wire trick and see how that does.
 
Why do you think it has to do 2.4? You make it seem like if you cannot get 2.4 that something is wrong. Not every CPU O/C's the same maybe yours will max at 2.1 or 2.2.
 
Personally, I'm thrilled with my 2.25 GHz O/C (2.4 GHz isn't rock stable for me). Getting 450 MHz "free" MHz from my core is fine by me! I'm just informing people that think they migh get a 100% stable 2.4 GHz out of a 1.8A that they are mistaken.
 
Hey I am happy it does this good and is perfectly stable at 2.2 at default voltage. What I don't get is why it will do this when it is set with the dip switches, but will not do it when set at 2.2 or 2.4 in the bios. That makes no sense. Maybe by doing the wire trick and making the default voltage 1.7, it will do 2.4 with the dip switches. You cannot adjust the voltage with the dip switches.
 
I read a review of this board last week and they had to set the Dip switches, not BIOS to get it to OC. Strange. R
 
RickH - this board is both. You can set it to jumperfree mode or use jumpers. Out of the box, it uses jumper free mode and there's no reason not to use this mode. It just gives you the flexibility of both, like many ASUS boards.
 
Yes, I am setting the voltage higher in the bios. This is how it is. I set it with the dip switches to 2.2, it is at default voltage and runs super. I set it to the same in the bios and it will not work. I set it to 2.4 with the dip switches and it boots fine, gets to WinXP start and locks up. I set it to 2.4 in the bios and it will do nothing, no post, nothing, no matter what voltage I set it to.
 
OK, I did the wire trick and it is now running at 2.4Ghz! I have been running Prime 95 for the last hour with no problems. This is using the dip switches set in the FSB 133 with AGP at 66 and PCI at 33. The wire is supposed to make the default v core at 1.7v, but the Asus PC Probe software says the v core is 1.84v.

I still don't know why the bios settings wouldn't work.

Try also running SETI and the 3d Mark 2k1SE demo looping for a few hours. I found that in some cases, it would be alright with just prime95 running, but when multi-tasking with those 3 programs, my computer would lock after a few hours.
