Hello everybody,
I haven't overclocked for a long time, ever since I got my AMD Thunderbird 900 @1150, so now I need some advise on the best way to overclock P4 3.2Ghz HT 800FSB. Here is what I want to achieve on Asus P4C800-Deluxe:
250 x 16 = 4000Mhz CPU
250 x 2 = 500Mhz DDR Corsair PC4000PRO CL3
250 x 4 = 1000Mhz system FSBWill watercooling be enough to maintain stable system? Which one would you reccomend?
Is this too much from P4 3.2? What other components of the system can such overclocking affect?Thank you for any comments, suggestions or references.

Read whatever you could get. But, I could not accept some of the "things" I read all the time.... mostly considering the source.
Asus P4P800 understates CPU temp by 10C in my case. I have two IC7, one IS7, and one P4P800. And, it overstates system temp by 7C.
You could take what I have for reference:
1) P4 800mhz overclocked 25-30% would not have heat problem using Stock HSF, provided you have good case ventilation .... not the one with a side panel fan blowing on to some temp senors on the board to make you believe the temp is lower.
2) I have no problem using Corsair, Apacer and Micron memory in dual channel. My PC3200 Apacer runs at 1:1 ratio all the way up to 510 mhz, or 255 FSB.
3) I don't have 3.2 but the (2) 2.4C and (1) 2.6C with HT enabled they reach 260, 270 and 255 FSB respectively.
So, you could see Processor of the same batch and speed might have different overclocking, thermal and voltage characteristics.
As for temperatures, mother boards seldom tell the truth ....
The joke is: The P4P800 overclocked to 3.34 ghz reports 27C idle and 41C full load. This makes many people happy and bragging the whole time, but not me .... because it is not a true temp.
The IC7, IS7 would report 37C idle and full loads of 58 C at 22C room temp.
Asus does not use memory ratio instead you pick the memory speed in the BIOS, i.e. 266, 333, 400. So, if you have PC3200 and overclock 30%, you must pick 333 as your base otherwise you would encounter CheckSum error. This is what I hate about Asus BIOS in favor of Abit.

One more thing ...
The highest speed from any processor family...i.e. the 3.2 is the highest in Northwood chip family, the LESS head room you have in overclocking. The very same reason overclockers look for the low end of the family and latest stepping.
The 3.2 indicates the ceiling in technology of that particular design.

I've got a P4 3.2 on a IC7-MAX3 with 1gb Corsair Twinx4000Pro. With watercooling. I hate to say it but the 3.2 sucks when it comes to OCing. I'm running it at aprox 3.7 right now. That's the best I can get. From what I've read 3.7-3.8 is the hightest the P4 can go.
I wish I had gotton a 2.4 or a 2.6. I probaly could've gotten the same speed I'm running at now with those, and it would be faster because of higher bus speeds. Oh well.
