Overclocking Asus P5wd2

[joe508]

how do i overclock my pc , i have p4 670 , asus p5wd2 bios 0606 , 2gb of Corsair TWIN2X1024A-6400 standard latency settings (5-5-5-12) ,video Geforce 7800 GTX ,Thermaltake W0049RUC Silent PurePower 680W, and Water Cooling (koolance Exos-2, Black )
i want to overclock the ai overclocking to manual in bios
and cpu frequency to 235
what should the other settings in bios be.

The P5WD2 is a nice board with great options, on the Intel side you can do no better for a feature rich, stable overclocking platform.

235X19? might be a bit much for the CPU but is nothing for the board. I would start with these settings.

CPU Lock Free........Disabled (something to play with later once you know max CPU Clocks)
Dram Frequency......DDR2-400 (or current FSBX2 -1:1- takes mem out of equation)
Performance Mode...Auto
PCI Express Freq.....100
PCI Clock Sync........33
Memory Voltage.......1.9V Unless MFGR calls for higher
CPU Vcore..............1.425
FSB Term Volt.........Auto
MCH Chipset Volt.....Auto
ICH Chipset Volt......Auto

Then go to "CPU Configuration" and disable "C1", "Thermal Control" and "Speed Step" and those sort of things so the Multi and volts are not changing while you are testing.

Under "Advanced Chipset Features" is where you change the dram timings (5-5-5-12) or whatever. I would be inclined to leave these at SPD timings until you know what the CPU will do. You can work on these later. "Hyper Path 3" is the only other thing to be concerned with but for now leave it on auto.

Like I said before, you may be asking a bit much of the CPU so I would start out at a little less FSB and work up slowly, testing with dual Prime95. I would probably start at around 215X19 and work up from there. Adjust the Vcore as needed to gain stability but I would be hesitant to go over 1.5V.

Once you know what the CPU max is then you can work on maximizing the Ram by tightening the timings and increasing the FSB which is a similar process to what you have already done. With the CPU Lock Free which should work with your CPU will give you a lot of flexibility also. For instance 235X19 is basically the same CPU Frequency as 297X15 which the latter should give better overall performance. One other thing is that a lot of times running the memory faster than FSB does not give much in the of a performance increase except in benchmark programs.

Just remember to keep it simple, work on one area at a time to maximize performance. Find the max CPU performance then work on memory and then tie it all together with the FSB.

Good luck.

Thank you for this very helpful post, you da man S_Wilson!

Welcome to AOA, joe508

Any progress with your overclocking project?

Would the p5gdi overclock the same as the p5gd2?

intels are fun to OC, as they have less of a FSB limit then AMD ith HTT.
