Multipliers and HTT speed, have I hit the limit?

post #1 of 4
Thread Starter 
So currently I can' get past a 315 HTT speed on my mobo without dropping my CPU to mobo multiplier from 5x to 4x and dropping the CPU from 10x to 9x. Is this beneficial? I mean everyone talks about upping the clock speed rather than multipliers helps because it speeds up everything. But what IS everything? I mean I can change the CPU multiplier, the CPU to mobo multiplier, and the RAM divider. Is that it? Are there more things that are affected by my clock speed?

If so, the do you guys think it would be good to drop my CPU to mobo multiplier to get a higher clock speed? Or would this start to defeat the purpose causing me to chase myself in circles with lower multipliers (and RAM divider) and higher clock speeds?

As always, thanks a lot!

Actually I should clarify. By "what is everything" I want to know what the clock speed affects. RAM, CPU, and CPU to chipset speeds I know. But if that is it, then there is no point in going further as now I have to lower all three of them in order to get a better clock speed.

If you need to drop RAM on a divider, and even drop the CPU multi in order to attain a marginally higher HTT, then that's obviously countereffective.

300MHz with multi 10 = 3.0GHz and RAM at 3:5 divider (Effective speed DDR2 1000) will give better results than 325MHz with multi 9 = 2.925GHz and RAM at a 3:4 divider (effective speed DDR2 867). To make up for the drop in Multi, you'll need an 11.1% increase in HTT to only match the CPU clock speed. (thus an HTT of 333MHz). RAM will still lag behind at DDR2 888 at that point.

So, you'll need to be able to gain quite a bit in HTT to make up for the drop in divider/multi/whatnot.

Yes, as far as the RAM goes, it seems the I can't get beyond 850MHz without being unable to boot up so I think that does it for the moment. I'll wait til my WC setup gets in. I might be able to mess with some voltages at that point.
