Default Overclocking P 4 3.2 HT 775 with MSI 915P combo MB

I don't know what the hell I am doing and never overclocked anything. I have a hell of a heat sink on the CPU and 4 fans in the case so I have lots of air going around. I am using cosair value ram (I know that is going to hurt me some). I didn't intend to overclock this thing when I bought it but I have all the stuff there to do something for it. The box says that there is all kinds of OC'ing this thing can do. I go into the cmos into the CELL part of it and it has these features. CPU dynamic overcl****ing and gives me an option to go from 1 to 15% on it, (but when you adjust it it doesn't adjust anything else). MY FSB is still 200, the CPU voltage is 1.3875, ddr voltage 2.6, nb volt 1.55 not sure what that stuff is though. it says ratio cmos setting 16. I am using this computer for video editing, no games or nothing but I need some power here and I need it stable but I want some kind of boost if possible, someone let me know what to do or something please.

Welcome to Pimprig!!

first of all, the d.o.t. stuff that msi has is worthless. and i have got some of my best overclocks with value ram for some odd reason, better than my corsair xms xl ram. your FSB is the ticket here. first, set your ram to run at ddr333--i think thats a 5/4 ratio--i could be wrong. your gonna have to do this with that ram.
set your ram voltage at 2.7-2.75----itll handle it--look at the specs of it--i think its 2.75. as for intel cpu voltages, im not for sure what they are supposed to be, but someone on here will know.

on my amd---i just started raising the fsb 10mhz at a time till it wouldnt post---then backed it off 5 till it did. then increased the cpu voltages slightly, and kept going.

the best person to ask would be $solid$ necro on this.....

First of welcome to PR.

Second, I wouldn't try overclocking at all since you don't game and video editing likes very stable rigs, or stock rigs. But, if you still want to do it I can help.

With an Intel 3.2 you have a high multi, 16 to be exact from memory so this will allow you to raise the FSB past 260 and be over 4.0 gigs. Pretty cool ha, never thought you would see 4.0 gigs? It is possible, but like Lwrs said you need to back your ram way down so although your CPU is overclocked, your RAM remains at stock or near stock speeds.

Go into your BIOS by hiting delete as you seem to already know. Go into advanced options or Frequency/Voltage control. From there, you will see the CPU FSB, the CPU voltage, RAM dividers, RAM voltage, Chipset voltage, all the goods. This is where my advise goes so far as everything is different and needs slightly less or more than someones elses.

I will tell you that the Intel 3.2 gig CPU can handle 1.54 volts and run stable all day for a long time. It can handle 1.65 as well, and I have had it as high as 1.756 which is about nuts..but I HAD the cooling.

You should have no issues geting to about 230-240 FSB by rasing your CPU voltage to about 1.45 or 1.5ish, add a lower ram divider like 5/4 or 6/5, raise your Chipset voltage a little. This will net you a small overclock that you can brag about.

If you want to grow some nuts and really take a risk then keep going. Go for FSB 250-260, for this its going to take a lower ram divider and high voltage. NOTE...Some LGA moboes are very unstable above 260 FSB using SATA, if you run into this problem you are screwed and there is nothing you can do except add a PCI-SATA card or go back to IDE.

On my Abit Ag8 board, I got to 3.9 gigs max WITH SATA, and 4.12 bootable windows on IDE. (maxed at 4.2) I used a 5/4 divider, and I ran a 15 multi, 260 FSB, 1.58 volts to the CPU...this was on SATA.
Without SATA, I had a 5/4 didiver, CPU voltage was 1.75, chipset was 1.9 volts, and I got to 4.12 bootable, but I don't recommend that at all.

I did run it at 3.7 gigs most days unless someone challenge me or some crap. I never had one single issue runing at 3.7 gigs too BTW. At 3.9 gigs, my SATA would cut out all the time at times.

Default Didn't get much out of it

Right now FSB is 215, DDR is 333, CPU volt is 1.43, DDR volt 2.70, NB volt 1.55 (not sure what that is) if I try to go to 220 it won't let me start windows it says overclocking unsuccessful, so I go back and raise the CPU volt to 1.50 and it still says it so right now the above setting is the only thing I can get it to boot into windows, any ideas?

NB stands for nortbridge, basicly your chipset...try lowering your multiplyer to like 14---and raising the bus more...

Never lower the multi with an Intel...its not an AMD. Plus, Speedstep never much works anyways with the 915 chipset anyways.

I would read up on some forums and see what others have goten. It could be that your SATA is cutting out really low which would put you in a hard spot. Just keep messing around with it. You will get it soon to where you want it.
