OC'ing a PII S.E.C how??

[ROH]

Ok, I'm wanting to OC a PII 266 SEC on a Kootenay sea440LX motherboard. Now the motherboard only has jumpers for setting the type of processor you plan on running on it. That's it. It doesn't seem to matter what setting you set it at it always goes by the chips default.

Now I'm an AMD person but I have this 266 rig I picked up for free and wanted to fool around with it. The manufacturer of the system is Seanix Canada, At this moment I'm not sure if THEY make the MOBO or if Kootenay is the manufacturers name.

Now I've heard rumour that the SEC mounted chips do not OC? Is this true? If not what do I need to do? Links to tutorials or whatnot would be great.

I'mnot familiar with that motherboard at all, but it does have an Intel LX chipset which is not a good overclocker to begin with. If you have any FSB settings above 66 MHz default, at most it would be 75 and 83, but not all LX boards would even do that. Sounds like you have a cheapie off-brand motherboard that is strictly automatic. If that is the case, you're out of luck for overclocking. As far as the P-II CPUs go, of course they can be overclocked, just not a lot. I had a P-II 233 that I ran at 75 MHz for 1-1/2 years on an Asus LX motherboard. It would go up to 83 FSB, but it got a little too warm for my comfort (I was poor back then and didn't want to fry it).

Thanks for the info! :)

I hope, I can get something out of this mobo, I've bin flipping a few jumpers that seam to regulate the clock speed on the board but the old settings that post, always seem to set the chip lower then the 266Mhz. I was able to get 133,166,200 & 233 but nothing over 266. Not to sure why. Could it be a voltage thing??? :rolleyes:

Anyways thanks for the reply.

Sounds like you're messing with the clock multiplier jumpers. If you're posting at lower multiplier settings, that CPU might not be locked. Some of the early P-II chips were unlocked. I've also heard that some could be adjusted lower, but not higher. Default multiplier should be 4X for a P-II 266. See if your motherboard has a setting for a higher multiplier and try it. If not, then the only other possible chance you have is to use a program like SoftFSB to change bus speed. I'm guessing your motherboard needs to be trashed though. Find another used board, preferably a newer BX chipset one like Abit or Asus that is fully adjustable. Should be able to find one pretty cheap. Only change the voltage if you have stability problems and then only if you have good cooling. You have yet to overclock the thing, so don't worry about voltage yet. Good luck.

Thanks for the info.

I've gone over the board left to right and back again and there is nothing to be used but those jumpers. :(

I tried CPUFSB and it detected the chipset and everything, even though it couldn't find the Mobo.
And any tampering with the settings at anything over 266Mhz just hung the system up really bad. I'm thinking your right about it being a lost cause.
