Help O/Cing P4 2.8C

[yourdeardaniel]

Hi, I need help overclocking P4 2.8 ghz. Does anyone have one and what are the ranges you can overlock it and at what voltages? I am using P4 2.8 Northwood, Asus P4C800-E Deluxe, 2x512mb Corsair XMS 3200LL PC3200, Thermaltake Spark7 HSF (is this better than the stock HSF?), Antec True 480 PSU, ATI Radeon 9800 Pro. I'm thinking of getting a different HSF like the Swiftech MCX478-V with Vantec Tornado 92mm fan. Give me OC advice please.

In a nutshell, since you can't adjust the multi with a P4, if you want to overclock, start cranking up the fsb. Oh, first change your memory to fsb ratio to 5:4. Also make sure your pci bus is locked at 33 mhz, and your agp bus is locked at 66 mhz, and you're on your way.

With a good heatsink and fan you should be able to get up around 3.5 at stock voltage or close to it if your motherboard undervolts. I am running at 257MHz FSB at 1.55V but I am using watercooling. I got up to 250 with an Alpha PAL before switching over to H2O.

I'm running a 2.8C M0 (14 x 250) with an Asus P4P800 using stock voltage (1.56 ~ 1.58 actual). Start with default fsb and bump it up 5MHz at a time until you max out. My cooler is a Thermalright SP-94 with 92mm Panaflo H and temps are mid 30's idle and mid 40's load. You should have no problem hitting 3400 ~ 3500 with your setup running 5:4 cpu/mem ratio. Just keep an eye on temps while you're bumping up the fsb. Let us know how it goes.
