what drains more power

well, I just ordered some new ram, its 2 x 512 ddr400 geil stick w/ heat spreaders.

Now I want to finishing oc'ing the comp, right now its running at 2.1ghz and I want it to run at 2.2ghz. When me and my friend finished installing everything, we put in one of his 512mb ddr400 sticks and changed the fsb from 166 to 200, and the multiplier from 12.5 to 11.0. We then ran 3dmark03 and during some of the tests the program would exit out, so we decided that my psu wasn't running enough Amps through the 12v rail and decided to drop the fsb to 166mhz and continue testing, so we did and nothing happened. Right now im running the FSB at 166mhz and the multiplier at 12.5, so my question is, what drains more power, increasing the FSB or increasing the multiplier. There are 2 ways to get to 2.2ghz, either drop the multiplier to 11.0 and increase the fsb to 200mhz or leave the multiplier at 12.5 and increase the fsb to 175mhz, essentially underclocking the ram.

Also, according to mobo monitor, all 3 of the voltage rails are where they are suppose to be at (the 3.3+v is at 3.32v, the 5.00+v is at 4.90, and the 12.0+v is at 12.0)
 
i have no idea what brand it is it came with the case but. The 3.3+v line is 3xA, the 5v line is 5xA, and the 12v line is 20amps.

the pc im running is a athlon xp-mobile 2400+
 
raising FSB and lowering multi causes more stress on your computer hardware (specifically RAM, Chipset, CPU) i would suspect that takes more power.

Simply upping multi and lowering FSB is the easy way out and yields less performance. Your RAM isn;t stressed and neither is your Mobo (well somewhat) if you still have stock FSB.

3.3v and 5v rails seem incredibly low at 3 and 5 amps. I wouldn;t overclock on that.
 
no. The 3.3v is at 30 something amps, and the 5v line is at 50 something amps.

So, it would be best to keep the multiplier at 12.5 and raise the fsb to 176mhz to get to 2.2ghz rather than lower the multiplier to 11.0 and raise the fsb to 200mhz? Right now im running the system at 2.1ghz.

oooooooooo the x=0 lol. my bad. thats fine then.

Yes, it would, if you want to keep stress down and stability up. Although the best results would be 220*10 lol.

Your Mobile 2400+ should easily do 220 1:1 if your RAM can to. But if you're having stability problems i can see why you want a lower FSB.
 
my ram can keep up, they tested it up to about 255mhz, and its a 200mhz stock. So if I get a better psu, and get some awesome cooling I could essentially and in theory run my comp at 3187.5 mhz. I think the mobo is limited to something like 220mhz fsb though, but I still could run like 2750 mhz, which would last me a long ass time.

Im not having stability issues, in the bios, everything seems to be stable, i.e. that the 3.3v line is running at 3.3v, the 5.0v line is running at 5.0v, and the 12.0v line is running at 12.0v. So I doubt an increase of 10mhz is gonna sap my system of power, the only power sucking thing is the vid card.

I remember reading about some guy getting one of these up to the 3.1ghz line.

If your chip can take 3.1GHz and you've got the right cooling then i don't see why it's not possible. Just remember not all chips overclock the same, so don't expect 3.1GHz until you get there lol. I am doubtful it's possible on any type of air cooling.
 
water cooling, i doubt it would require liquid nitrogen...but a water chiller maybe. keep your room cold and have the water line go through a bucket of ice and water. liquid nitrogen is for like 2000MHz overclocks lol.
 
well, I oc'ed the processor and the graphics card about 100mhz and the voltages are stable, no more than 3% fluctation.
 
I have found that the Geil Ram needs to have close to 3.0 volts to run reliably, mine runs fine at 2.9v.
 
the ram is running fine, at least thats the way it looks. I set it to auto detect everything, so it might be running 3v.
 
We then ran 3dmark03 and during some of the tests the program would exit out, so we decided that my psu wasn't running enough Amps through the 12v rail and decided to drop the fsb to 166mhz and continue testing

Well neither will increase power drain (for equivalent utilization) until you bump vcore. Of course just because it passed once doesnt mean it will pass twice or 1000 times :)

Ok you dont bloody need to bump everyday

Its not. That mobo doesnt punch up that high (i dont think it did... been a long time)
