Overclocking an Intel 630

post #1 of 4
Thread Starter 
hello i was wondering if any one has same mobo/cpu combo i have listed below? I had my system to 4.5 and in windows but it ran little hot 70cel. im running 667 ddr2 and was looking at the ddr2 8000 ram i seen a system with that combo running at 4.5 stable so i guess my ?? is do i need that 8000 ram that runs at 1000 mhz or can my 667 do it i just need to play with it more or go water cooled???

and any htpc ppl here ??? as you could guess this comp is my htpc hooked to a 56 inch hdtv looks great

The Asus P5WD2 Premium you got is one of the best overclocking mobos on the market today.

Your P4 has a multiplier set to 15. So when you run it at 4500MHz you are actually setting your FSB to 4500MHz/15 = 300 MHz.
Alright, now your 667MHz DDR2 modules have a real frequency of 667MHz/2 = 333MHz (since they use DDR technology).

So you still got 33MHz headroom for overclocking. I think your RAM will even go higher than the rated 333MHz (667MHz effective in DDR2) if you loosen the timings. So I'd say try overclocking with the RAM you have now before paying for DDR28000 which would have a real speed of 500MHz (1000MHz effective in DDR2).

One last thing, 70C is too high for the CPU you have. Try keeping it below 60C.
I wouldn't be surprised to see that Thermal Throttling is being activated on your CPU.
With such overclocking (50% from 3.0 to 4.5) you definitely need a good water cooling system.

Before you buy any new RAM, or anything else, you HAVE to get those temps under control. I have to agree, with those temps, the only way to get a safe operating temp is with water. You could try a Big Typhoon with AS5 and get down to the mid to high 50s, but you need to do something about those temps.

Chances are, you're not really running at a real 4.5 as the CPU is probably throttling back from the heat.

Cool that beast!

I've had almost the exact setup that you have currently and IMO you're fine with your overclock with your current components, just go for a self built wc setup and you'll probably be able to get an even higher oc when you get your temps down.
