FSB question for oc Q9450

[nes]

I would like to do some noob-style oc-business with my current setup. I have a few questions for the savy. I am currently running my CPU and Memory 'unlinked'. My FSB is running at 1333mhz and my memory is running at 1000mhz @ 2.21V. The CPU Vcore is set to auto but CPU-z reports voltages at 1.26.

I would like to run my CPU at 3.0ghz. So, I would have to increase my FSB to 1500mhz, yes? And for something like 2.8ghz I would have to increase my FSB to 1400mhz, right? Would I have to do anything to my memory settings, voltage or otherwise? I would like to achieve the 2.8ghz on stock voltages, as it is my understanding that this will do nothing to increase temps.

I have googled alot and found several success stories with OC's @ 2.8ghz w/ q9450 on stock voltages. I like the performance of my memory at its current settings and don't really wanna have to reduce the performance of memory for increasing the FSB. I don't like ratios or linked memory and cpu stuff but if I have to I have to.

Also, will Asus's crash free BIOS allow me to hardboot and get back into the BIOS if I jack-up an OC and it's not stable upon Vista Boot?

to get your actual cpu speed , multiplier on cpu x ( fsb / 4 ) = core speed on nvidia boards . y nvidia does things different is totally beyond me .. so u will need 375 x 4 = 1500 on a nvidia chipset .. on nvidias allways divide the fsb by 4 to get actual fsb then multiply that number by the cpu multiplier . as with any overclocking , only adjust the fsb by 3 ( nvidia is 12 ) boot into windows check stability ( benchmarks and such , if pass continue to up fsb by 3 ( nvidia is 12 ) then continue till windows doesnt load or instability in benchmarking occurs then back off fsb by 5 ( nvidia is 20 ) . if you fsb goes above 400 ( 1600 nvidia ) u may wanna consider linking the memory ( 1:1 ratio )

You don't want to run 1:1 with ddr2... DDR2 1066 running at 1600 is a bigger than posible OC in most cases.

LOL ... u dont look at the quad pumped fsb . but actual fsb is , if memory is @ 1:1 with the fsb and he sees 1600 thats quad pumped so divide that by 4 1600 / 4 = 400 fsb .. so his memory is only @ 800 mhz ... nvidia shows the quad pumped fsb ( actual bus speed of the board ) not FSB ..

LOL, its time you play with recent stuff miker :grin:

@OP Ratios and dividers are very easy, just like math in grade 5

2.8ghz on stock voltage. Cool chip.
