hi,

i have managed to over clock my cpu P4 524 to 3.81 Ghz and its running stable, i have a xfx 8600 Gt Fatal1ty installed, on these setings 3d Mark gives a score of 8514, but when i try to over clock cpu more, the scores decreases and i could see the difference in the 3d mark tests as well.

The Temp of the CPU on load goes upto 55C.
The voltage i am currently giving is 1.4825 v

ive tried to take it to 3.91 with voltage of 1.5000 it was not stable, i checked with orthos, then i increased the voltage but same it was not stable, while running orthos the cpu temp on load was 56C, is this the limitation of my board? or CPU or RAM

I have a simple ram TwinMoss DDR2 533

or do i need to have a combination of 1:1 to overclock more

Stock settings are 23 x 133MHz? So apparently you've jacked the CPU freq up to approx 166MHz? What speed is your RAM running at? For best performance, you should maintain a 1:1 ratio. In other words, it *should* be running at 166MHz (DDR333) to match the CPU. If you left it at 266MHz (DDR533) & overclocked from there, the RAM may be what's holding you back.

Also, make sure to lock the PCI at 33MHz & the PCI-e at 100MHz, & disable any Spread Spectrum settings.

yes jam spot on.


ram is currently at 322 mhz 4-4-4-12, i dont know how it is at that much should be at 266+33 = 299 because i just increased the cpu by 33 mhz.

pci-ex also at 100 and pci at 33 mhz

sorry for the typo in above mesage the ram is at 332 mhz


got my awnser my self by stresing brain lol

its 1:2 ratio so if processor is at 166 the ram would be at 332.
