Hey, I'm new to Intel overclocking... but since I've been working on my Bro's rig I thought I'd OC it a bit to give him a little more edge on his games.

This is his rig.

Celeron D 330J 2.66Ghz prescott core
Asus P5RD1-V mobo 775 socket
1gb Corsair XMS 3200C2
MSI 6600GT
80gb IDE western digital hd
lite on DVD drive
stock cpu cooler
3 80mm intake fans, one 120mm rear exhaust fan and a blowhole on the top of his case (Aspire X-Dreamer II case)
Sunbeam nuuo 550w psu

Alright, so I set the spectrum to disabled, set the RAM timings to 2-3-3-6 (which is what they should run at DDR400 so there shouldn't be an issue)
the vcore is 1.3125 and vRAM is 2.7

I upped the fsb to 150 which puts me from 2.66Ghz to 3.0Ghz with a 600Mhz FSB speed. I haven't primed the system yet, but the idle temps are 38.

I guess what I'm asking is there anything else I need to be doing? what are the voltages and temps I should aim for w/ this core? what can I expect to get with this setup? I think the only limiting factor will be the cpu as the mobo supports a 800Mhz FSB and the RAM should get to about DDR500 and right now they are only at DDR300 (I think)

PCI-E/AGP/PCI locks should always be locked to make sure the system stays stable. These should be clocked at 100.0MHz/66.6MHz/33.3MHz (you will either have PCI-E or AGP depending on the board model).
As for voltage and temperature limitations I would keep the CPU below an average of 65C and a maximum voltage of 1.525v

That CPU will overclock well if those are met, Speed Spectrum should be disabled (which you have already done)


Looks good so far.

Note: Your board is rated for 800MHz FSB but it will be able to operate fine with FSB speeds above that, the same with the memory speeds.

Alright, thanks for the help. yeah, I have the PCIe set to 100. (I know all that from OC'ing AMD) I just forgot to mention it. I did not see anything to lock the IDE drives... so I'll have to look again in the bios for that.

I am a little confused about the RAM though. how exactly does it work... RAM speed should just be double the FSB, correct? If so, then I wonder why it won't work when I put the RAM speed to the CPU speed. I have to leave it on AUTO. Sadly, both memtest and cpu-z are unable to determine the memory frequency.

well I double checked the bios and there aren't any options to lock the pci ports or the ide... so Idk. there is a pcie option and that is set at 100Mhz.

I did run prime95 all night and it is stable 13 hours at 3.2Ghz load temps are 43-44

alright in the interest of not just adding more posts I thought I'd just edit my last one.

I checked the bios once again to find a pci frequency or a way to lock it... didn't find anything.
I upped the vcore a bit more and tried to get 165Mhz FSB... but it won't boot. I'm wondering if it is related to ide devices... or are they locked automatically? I know it's not a power or temp issue.

bumb... anyone know why I've hit at wall at 3.2 when the temps and voltages are low? does it have anything to do w/ not being able to find anything about locking pci slots or ide?
