Celeron 667 overclocking with ASUS P3V4X

[Perryg114]

I just bought a Celeron 667. Currently its in an ASUS P3V4X motherboard. Correct me if I am wrong but the new Celerons and P-III's have a fixed CPU to Bus ratio. In this case it is 10x. 10 x 66Mhz = 667Mhz. Problem is the ASUS only supports ratio's up to 8x. It would be nice to run at a 100Mhz bus speed which means that the CPU would clock at around 1G Hz. This may be a bit optimistic. Oh yeah I have an Abit slotkit adapter to adapt to the FCPGA Celeron.

Your probably going to tell me that I should have gotten a Celeron 600 to use this board.

You should have gotten a 600 to go with that board. Hah Hah

Give it a shot. It may be your lucky day. You will definitely need to increase the voltage.

the cpu is multiplier clock locked so settings for multiplier on the m/board are irrelevent. just bump up the fsb & see if she stays stable!
hope you've got good cooling!
good luck

Dont worry about what your board has for Multipliers. It will work just fine. My old ASUS P2B only had multipliers up to 5.5 and I tested a few 633 Celerys at 950mhz on it(9.5 x 100) I never changed the multiplier on the board. I just left it at where it was from the factory.(Jumpers)

With a P3V4X like mine, perhaps you can aim at 880 ( 88 * 10 ) or 910 ( 91*10 ), i don't think
you can hit the 1Ghz mark, without some kind of active cooling anyway...

Then again you might be lucky....give it a try...

I have a Celeron 633 that I run 1026 in a CUSL2-C. Had to bump the voltage to 1.9 to get it to run stable at this speed. Temps run about 42 C.

Well guys I tried it last night I could only get up to 75MHz on the bus which is a processor speed of 752 Mhz. It would not even boot at higher speeds. I went as high as 1.75V on the voltage. FUnny thing is when I went into Sandra it reported a Vcore voltage of 2.1 V. Now is something wrong here. Internal CPU temp topped out at 50C under the Sandra burn in test it dropped to around 40 at idle. That was at 1.75V. It ran just as well at 1.7V so I guess I will go back to that Voltage if I can't get anymore out of it. So why won't it boot at higher clock speeds. I thought it was a cooling issue more than anything else as to how fast you can go.

Get a namebrand high-quality slotket.
It makes a difference overclocking these Celerons.

 

[Perryg114]

Its an Abit Slotkit is that no name brand.

Ok guys do I need to set my slotkit to coppermine. Also what is the difference between the settings. I am thinking the celeron setting may not allow overclocking of the FSB beyond 75 Mhz. Could this be why I can't get the past 752 Mhz on the CPU.
