4 : 5 my memory:FSB ratio.
So you must consider: 299 : 4 x 5 = 373.75 x 2 = 747 MHz the actual speed at which the mem is running.
No, if you are running a 4:5 ratio at 299Mhz FSB your memory is only running at 239.2Mhz....

Check his CPU-Z screenie. RAM is running at 373.9MHz external. Which equals DDR2 747.8 speeds. Still, if it is causing troubles at that speed, it ain't right, since it's DDR2 800

And the ratio is FSB:RAM = 4:5 (he accidently flipped that around in his post)

And the math is correct: 299/4*5*2 = 747.5

ok well I have the same cpu so ill tell you what my settings are for 3.2 ghz. Thats the easiest.
Set the bus speed to 400
Ram to 1:1 or to 2x
Vcore 1.34-1.4 (i only needed the stock voltage of 1.325 to make it boot but it fails prime kinda quickly)
pci lock at 33
pci-e lock at 100
leave ram voltages alone since ur ram isnt being overclocked at all
Hope this helps

Thank you!
Disable the auto then you can lock it at 100.

Thread Starter 
Friends,

I tried a lot of things and also increased the voltage in all the areas my mobo lets me do.
I pumped the FSB till 340 and was able to boot in Windows but only for a few seconds.
Then I had to clear the CMOS in order to make the PC start again (not Windows, just the boot).

I tried a 333 FSB and sometimes the pc didn't complete the POST, sometimes could boot in windows but was not stable at all!!!
I reduced to 310 and for a couple of hours it could go, not more...

I'm really getting crazy.... the only FSB stable frequency I can get is only 299...
I'm starting to think some of my equipment (CPU or mobo or what the hell) isn't just capable of OC.

I need your final advice before giving up...

Thank you guys.

If I was purchasing a system for overclocking, I would never have looked at Foxconn. ASUS P5B-E Deluxe, Gigabyte 965P-DS3 would have been my two choices. The ASUS for E6600 and higher and the Gigabyte for E6400 and lower.

Sorry to give you bad news but I do not think you will get much joy with that board.

Don't see anything unusual there.. how much amps can that PSU push??

Only thing you might try is pushing RAM further down (set it on 1:1) just to rule it out as a possible cultprit.

I have to concur, however, you can't forget about the P5W DH rev1.1 or the P5W64!

Do what Chozart said. Rule that out first.
BTW, can you please go to the top of this page and click USER CP then fill out your specs by clicking add system on the left.
Can you show a link to what PSU you have?

They are not as metionable as the P5B Deluxe and the DS3. No offense, but the P5W is not even close to the Ubergoodness in OCing of the P5B deluxe.
