I have a P5ND2 SLI MOBO and can reach 1066 FSB and a P4 6XX H/T 800 fsb ,,, is it o.k. to OC the CPU fsb to 1000 MHZ ???

If you like setting your computer on fire then yes, otherwise no.

Lol talk about some crazy high FSB. FSB is quad pumped so if you set the FSB your CPU's bus would be running at 4000 mhz. Overclocking takes time, you are going to have to figure out for yourself what your chip can take. Read wusy's guide to overclocking a C2D (if that's what you have)

I'm guessing that you meant your mobo can reach 1066 FSB aka 266MHZ and the Pentium 4 is 800 FSB aka 200MHz, correct? So your target would then be to go an extra 50MHz above the stock 200 to 250 or 1000 FSB?

Sounds possibly doable, but I can only speculate since I have no oc experience. All I can do is echo what's already been said. Try reading the suggested guides and incrementally increasing the FSB clock speed as they outline and see if it works. With a Pentium 4 what you probably need to keep an especially close eye on is your CPU temp.

-john, who should know better but obviously doesn't

I think he meant 250FSB quad pumped to 1,000FSB and he has a P4 6** series.

current settings:

CPU
core speed--3800 mhz
multiplier-- X16
buss speed-- 237.5 mhz
rated fsb-- 950-- mhz

RAM TIMINGriginal setting-mushkin 266 4-5-5-13 dual channel 2 gig
NOW:
frequency-- 237.5 mhz
fsbram-- 1:1
cas# latency-- 2.0 clocks
ras#to cas# delay-- 3 clocks
ras# precharge-- 3 clocks
cycle time (tras)-- 5 clocks
bank cycle time (trc)-- 9 clocks

I used S&M to test the hardware and did not find any problem (95% load long) it took 7 hours to finish. the whole time the test the TEMP for CPU 36-37, for MOBO is 36 all the time....
it do not hang up even on heavy load....

Is this one of the 65nm chips or is it a 90nm version?

65 WHAT IS THE DIFFERENCE ???

Smaller manufacturing process. Less power consumption and higher clocks. At least that's what they told me :?

Best advice i've seen all day.
