Hi,
I have a Cyrix MII 266 Mhz. Processor and I was wondering if you could tell me how overclockable it is. Could you tell me what is the most I could over clock it to without it overheating or damaging any of my componants. I have PC100 SDRAM and A fan with a heatsink and ceramic plates to draw the heat away from the CPU. THANKS.
Why overclock it? The little bit of speed you gain isn't worth it and might cause more problems down the line. My AMD K-5 133MHz runs faster then some Intel 350's. Just keep your pc clean of junk files and it'll be fine.

The amount of speed gained by overclocking is definitely worth it. But you must have a good large heatsink and fan on it, try to improve system ventalation by adding a case fan. Cyrix CPUs are the least friendly to overclocking because they are already pushed hard. Be glad you already got you money's worth. If you bought an intel for the same price you would have a plain 133mhz. Hey, there is no reason not to run that AMD at 166mhz! If Windows ran as nicely as an overclocked CPU this forum wouldn't be here!

ive had a 233 and a 300mII cyrix...and found...with a few different motherboards...that the only reliable overclock is the smalleest increase only...ie..a 233 goes to 266...no more..a 300 goes to 333..ive tried 350...366 ...and i runs fine...boots up...some programs are fine...even beenchmark programs work...but games tend to hang a lot...ive tried various cpu voltages...bus speeds...multipliers...and i found cyrix best run on a small jump in bus speed only...ie...it can handle a jump from 66 to 75...but if you go to 83..95...or 100...it seems to hang...it cant handle the pace..even after reducing the multiplier as low as 2.5...no luck...heat is not a terible component....cyrix just cant cope...they are running flat out already.

Don't even try to overclock your cyrix. I have talked to cyrix before and they said that MII's are pretty much overclocked out-of-the factory. When you get one in your computer, it is probably already overclocked. I guess that's why they run flat-out already.

Don't even bother, just go and buy a AMD k6-2 450 for $69.99 and throw that cyrix in the trash. I am saying this because i once had a 266 cyrix and it sucked. Take my word for it, go with AMD because you can't use intel without buying a new motherboard.

i also agree with response #1. In my case overclocking brings more bad then good. Just "Keep it clean"

Overclocking a Cyrix should give you a rather small performance boost. The Cyrix MII is overclockable, but it isn't an overclocking star. Whether it is worth it is up to you... I overclock mine mostly for the hell of it.

I overclocked my Cyrix MII-266Mhz to 300mhz.
Before overclocking the bus speed was 83mhz and multiplier 2.5.After overclocking the bus speed was 75mhz and multiplier 3.I have win98 and when I overclocked my CPU win98 boot in around 45 seconds,before that they boot up in 2 minutes.

(maybe a bit late)
My MII (3.5x on a 66MHz bus - 300) works fine
under windows at 333. Games tend to push it a bit, but the extra performance is worth it.
You're best off with a motherboard like mine...BIOS lets you set the clock from there!

Dude I play halflife a real game that depends on 3d and my cyrix 266 sucks! The thing has no special atrributes like 3d now! I got my k6-2 500 mhz with 3d now and now my cpu is faster than 4 times the freacking cyrix and the cyrix 266 is at 200.1 mhz if you all didn't know.

Just don't overclock it. Buy yourself a voodoo3 3000 or 3500 and get up to 128 mbs of ram. For some reason, that works just fine on my mii-300 (un-overclocked) and I play descent 3 & unreal tournament with no problems.
that or go out and buy yourself a k6-2 or k6-3 450

I have cyrix 333
Unreal Tournament and Quake2 runs OK but Quake3 Sucks big time, I'll never buy Cyrix agaiun!!!!!!!!! 17 fps

Cyrix runs windows 98 just fine get more ram
a voodoo 3 and keep it clear of crap
dont overclock it or itll blow!

i have a cyrix MXII 333 which i have successfully overclocked to a 400... but to be honest... the 285mhz true speed is not worth it as my windows is about as reliable as a condom stuck to a hedgehog... should have bought an AMD...

I have a pentium 166 mhz, a Cyrix MII and a K6 2 3d Now 500 mhz. The MII is a good idea for Work in windows, but for games Not. My 166 works better in some games. I i think that overclocking a MII 300 to a 333 is not the solution and the life of the MII is to short. The best think that you can do is buy a AMD K6 2 500 it's works really good

same advice as most. next step oc. from 266 to 300 would be your best bet (166 to 200). i've worked on 333 o/ced to 400 on cheap tx pro2 mobos (292 @ 3.5 x 83.3/3.2v. 83.3 is kinda picky messes up the pci sometimes tried 300 @ 4 X 75 but the 292 was better. change blower to a bigger/higher cfm heatsink w/more surface area and installed a fan/blower from a defective power supply. not much on games but works ok with ms office applications. slower than my amd k6 2 500 @ 550.
lots of luck. if your burn your cpu, that will be an excuse to buy and amd

Hi,
I have a cyrix 233MMX. Sometimes my system stopd responding and I can't do anything at all. I am just wondering if it is the CPU over heated or the HDD problem.
Ay ideas is appreciated

Im going to be honest cyrix has the worst fpu known to mankind only to be defeated by the mobile version of cyrix overclocing a cyrix is like feeding a camel a thimblefull fuggedaboutit if you want better speed get an amd if you want falt out better speed get an abit board and a p3

What you lookin to do here? Cause some kind of nuclear reaction in your PC case? OCing a cyrix is insane!
I wouls STRONGLY RECCOMEND AGAINST doing it, you may just cause some kind of temproal flux inversion causing a rip in the space time continuum which would single handedly cause the world to be destroyed as it flux mechanics are completely inversed due to the impossible levels of heat generated by the center of an Overclocked (Pre overclocked) cyrix CPU.

stumpy would know. There are many laws against overclocking a Cyrix. In many places Cyrix has been banned altogether.

I'm listening to all you people rip apart cyrix.. and eventually someone will point it out.. Cyrix was designed to provide a decent replacement from Intel or AMD for about half the cost. I bought my MII 300 when Intel released it's first 400. I got the motherboard and the processor at a show for $149. I have 80 MB Ram on that thing and it runs better than most peoples 500's.
Sure I'd love to have an Athlon 1100 (which just started shipping recently). But I don't have $700 to drop on a processor alone.

Oh give me a break will ya,s cyrix??? please.. Why overclock a chip that cant even handle its own speed now it runs way to hot, life may be 1 day to 1 year if your real lucky do yourself a big favor replace with AMD K6 far better chip. Better get them before there gone coz the ATHLONS & DURONS ARE HERE TO STAY. Ps stay away from intel the giant has fallen to the new king AMD BTW
A k6400 would be a good combo with a P5A ASUS MOTHERBOARD ADD 128 MEG RAM HP OR PHIL BURNER DIAMOND VID 32 MEG CARD OR VOODOO 3 2000 16 MEG CARD ADD A SB LIVE AND 15 GIG OR BIGGER HARD DRIVE AND WAIT TILL THE 2 gigA mhz cpus come out PEACE LOVE AND THE FUNK PEOPLE.. ME 2 CENTS WORTH.....

I have a cyrix 233 MMX, I overclock it to 185 MHz.(PR 300)
I compare my computer with others and I
see, it realy run fast!!
Plus I have a vodoo banshe 3D card and 64
Mb of memory in my machine.
Itīs working about 2 years,donīt burned, and Iīm sure my machine is faster than some pentium 2 or K6 2 to play games.

If you really want to know how fast your CPU is go to wintune.winmag.com and run the wintune tests. You will see just how slow your Cyrix 233 MMX really is.
You will be embarassed to come back here and give the results. Cyrix is a joke.

i have a cyrix 333MII, and i haven't bothered to overclock, i run Quake 3 on it with 128mb of ram, and a 12mb Voodoo 2, and it goes at at least 28fps in most parts, this just goes to show that if you manage your comp right, defragging it etc. then your s---ty little cyrix can doo a good job, the only time my processor gives up the ghost is when i try running IE 5.5, 3D Studio Max 3, and Photoshop at the same time, just for a laugh. But before eyou all laugh at me, i will be ying a new comp next year, like an athalon 1266 by then, and i will kick cyrix's arse...severly..

I suggest that you don't overclock your computer. Just maintain it well(scandisk,defrag etc.) and it will work fine.Buy 128 of ram and gforce DDR and your be a teacher with a burning comet on his pants.....zzoooooooooooommmm... its dirt cheap!!!! I play motorcross madness2,CS version I and Diablo II but i think i will buy a Athlon 1GHZ next year!!

hehehehehehehehe,
I agree, keep clean and only o'clock a little - to give yourself an excuse to buy a real chip.. Good cheap alternative though..
