help OCing

post #1 of 12
Thread Starter 


I can't get past FSB of 230. My old ram (corsair Value select) I was at 312 before I stopped. All I have changed was the ram. What does the FSB/DRAM CPU/18 mean?

CPU/18 is the divider which you have your current RAM excessively underclocked and that is apparent by the 115.5 frequency showing ion CPU-Z.
Are you set @ 100MHz... ie.DDR200? That what it looks like to me!

On the CPU voltage, you may need about 0.1v bump up on the CPU for higher OCing. Whatch your full load temps ak keep the max below 50c.

You have the Bus running at 230MHz. You are effectively running the memory at half the Bus speed. So your divider is either set to 1/2, 100MHz or DDR200.

A few things can cause this:

Have you lowered your HT multiplier to 4?
Are your PCI and PCIe speeds locked (at 33MHz and 100MHz I think, in that order)?
Is your hard drive plugged in the SATA ports provided by the northbridge, rather than those provided by a different chip? (Some of those 'different chips' hate overclocking)

If you have an nForce 4 chipset, you won't need to increase chipset voltage up until 400MHz-ish.

Thanks for the info, this is what I know
HT is at 3 as of now
PCIe is at auto?
I have 2 SATA harddrives

Just not understanding why since installing another harddrive and a different set of ram, my OC is limited?
