I wanna get in on the action, where do I start?

[narzy]

good Beginers guide to OCing, Im gonna start with a Cyrix socket 7 if at all possible .

thanks

 

[kw3i]

cyrix? i dont know anyone who has a cyix, if anything try a duron: )

 

[narzy]

ya I know but its a cheapo chip, cost me noting . so I figured it was a good start. where is a good guide?

narzy....I had a Cyrix for 3 years....if you want to overclock, it's just like any other socket 7 chip in that respect, except one: they don't overclock well (they are practically sold overclocked as it is).

Catch me in IRC sometime...

Ummmm, Cyrix's are notorious for being SUPER hot. A chip that is super hot, to start off, is not going to fair well when you try to make it go faster, causing it to heat even more. Depending on how much $$$ you have, I would reccomend picking up a Duron 600 or 650 for about $50 and a KT7 for about $120 or so.

Super hot? LMAO. Yes, for chips of it's erra, it was super hot. But that chip doesn't go above 27 watts max (unless you overclock it). That's in socket 7. Now, take a T-bird 1.2 ghz. Now you're talking 66 watts. Okay....hym........which one's more?

Cyrix's were only 'hot' for their time. They're certainly not hot by todays's standards!

Oh yeah, he's overclocking this chip because it's a project, not because he needs this as his main computer

 

[narzy]

ya its a project

as for heat we dont think thats going to be much of a problem, we have a special lil sumthin up our sleaves

but I still need a tutorial on how to do it! thanks

Tutorial for overclocking that POS:

Make sure you have dasmmed good cooling (done):

Change the multiplier to as high as it can go (most older Cyrix M2's have a multiplier of no more than 3.5x, which is a remap of the 1.5x multiplier).

I would set it to a 2x multiplier, then raise the FSB until it is unstable. Keep it at that FSB, and raise the multiplier.


If it doesn't work, lower the bus speed and up the multiplier. If you still can't, up the voltage from 2.9, up to, say , 2.9 (you are saying that cooling isn't an issue). 3.2 is the maximum tolerance of the chip, at least, according to the tech docs.

Since you don't care about the longevity of this chip, up the voltage as much as you need (I think the highest you'll be able to get is 3.3v)

To get 3.3v, just change the voltage from dual voltage, to single voltage (used for old pentiums). The I/O voltage of older boards is 3.3v, and when you set the chip up to single voltage, it sets the chip to 3.3v as well.

Some of the chips did, infact, have multipliers up to 4x, but usually not. Remember, Cyrix useed the annoying PR rating.

FWIW, here's a listing of the PR ratings:

PR133: 100/50, 110/55
PR150: 120/60, 125/50
PR166: 133/66, 137.5/55, 150/50, 150/60
PR200: 150/75, 165/55, 166/66, 180/60
PR233: 166/83, 187.5/75, 200/66
PR266: 207.5/83, 225/75 (6x86MX), 233/66 (6x86MX)
PR300: 225/75 (M-II), 233/66 (M-II)
PR333: 250/83
PR366: 250/100
PR400: 285/95
PR433: 300/100

 

[narzy]

any suggestion on what mobo I should use for this?

 

[narzy]

not inless this thing would go over 450* F Ln2 gotta love the cold!
