805 overclock

ive purchased the 805d chip and a asus p5vd2-mx motherboardm and the Arctic pro cooler. The problem is i carnt get is past 3030ghz, thats on a clock of 152. Any ideas how to get it faster, im a noob at this as you can prob tell. How do i change the voltage because that comes into effect aswell, i carnt see an option in the bios? cheers fellas

Hi,

you need to post full PC spec, preferably in ** sig. Also read the sticky overclocking thread in this forum

Im using an Asus P5vd2-mx Board, 1gb Corsair ddr2 533 ram, Arctic Freezer 7 pro, it just wont clock past 150mgz

That's a good set up. Maybe your ram limits you from passing 150 FSB.

*Your ram is rated at 533MHz and you should be able to overclock up to:
533 divided by 4 = 133.25 (that equals the stock FSB for Pentium D 805)

*If you increase the FSB to 150, the ram will be rated at:
150 times 4 = 600MHz (67Mhz more than its rated speed)

IMO corsair's ram should be able to handle 67Mhz more speed than its rated speed...or maybe not. Try increase the memory voltage of change the cpu/ram ratio. Go to DRAM Frequency in bios to change the speed of the memory. For the memory and cpu voltage, it will usually be on the bios as Vmem and Vcore voltage.

cheers mate, ive been trying to change the voltage of the cpu but is dosnt seem to let me do so, it just has the option of 1.24 ( which changes between 1.24 and 1.26 all the time ) and the option for ignored. Can i change the voltage or is my board not letting me?

Hrmm..you only have the options for 1.24 and ignored? :confused:

In the bios, did you go to the Hardware Monitoring in the Power tab instead of the JumperFree Configuration in the Advanced tab? You're supposed to go to the advanced tab. I'm not sure whether our bios interface are the same or not but it shouldn't make any much difference since both of our motherboard are from asus.

I've downloaded the manual, and it looks pretty much like it's not a good overclocking board. The max FSB appears to be 166. The only advice I would give is to make sure that the PCIe/FSB lock is set to ASync otherwise it will crap out early.
