i can't increase my Bus Speed greater than 320MHz

post #1 of 7
Thread Starter 
I built my new system for a few months now, and i just bought a pair of 2GB Crucial Ballistix PC2-6400 for the system. However i still can't increase the Bus Speed greater than 320MHz on bios if though i changed the settings to unlinked and reduced the memory clock. I also tried to increase the CPU voltage from 1.3V(stock) to 1.46V but i only managed 3 seconds of stable run
srry i am a newbie at clocking, i'm thinking maybe my motherboard isn't capable.

plz tell me how i can increase the Bus speed more, and do i need to upgrade the motherboard?

thanks for your help

p.s. it's just freezing on bios boot up, not overheating

To determime a motherboard's max FSB you have to slow down the CPU too, with a lower multiplier. What multiplier are you using at 320? And can the CPU do that?
(FSB x Multi = ?)

Use a multiplier that will keep the CPU at, or below, it's rated speed of 2.4 Ghz.

Where you're at now, you don't know if the motherboard can't do better than 320 FSB or whether the CPU can't do more than 2.88 Ghz.

At 320x9 what does CPU-Z say your memory is at?

I unlinked the Memory and FSB clock, and the memory clock is 554MHz when FSB is 320.

I also tried lowering the multiplier to x6 and same thing occur. frozen bios when FSB= 320. in fustration i raised the CPU voltage from 1.3v to 1.6v(max on my mobo) but same problem.

Is it my CPU? or mobo, cos i'm thinking of upgrading to a Biostar after the new year, do u reckon it will help?

Up the North Bridge voltage to acheve higher FSB clock not the CPU.

After you hit max FSB or the FSB that your shooting for then go back and adjust the CPU multi up one and adjust the vcore as needed. Repeat this until you max out.
