Can teach me to oc AMD-K6 II 3D 450 ???

Im from Malaysia and im new in overclocking a cpu.Can u all teach me how to oc the cpu?
Last week..i try to oc the pc by increace the multiplayer..it's work at 500 but in 550..(windows protection error)..
I used fan for my cooling system bcoz it's cheaper than water cooling..at malaysia...the price is RM 800 ($200 US dollar ) for water cooling..it's too expensive to me..ok..bye...
sorry....im not very well in english

how about raising the voltage?

try 2.4 or 2.5

Hey Bovon every time some one ask's about overclocking a K6 you say ( the K6-2 series cpu's did not overclock too good )
that's a crock of bull.

some of the k6 chips did not one of them was your's, to bad for you but that is not all of them and the K6-2-450 was not one of them. any and all of the 2.2volt models of the K6-2-450 should and can be overclocked to at least 550MHz.

if you cant help be quite please.

That said
fierra If you would post what motherboard memory and other devices you have in your computer and also what you have tried as far as overclocking goes we can help you get a few more MHz out of that chip

you can also take a look at the oveclocking section here on sysopt some very good info there
and you can check out what I have done with a K6-2-450 at my web site www.comppwizz.com

never realy had much luck with the old style k6's they run too hot if you pump too much voltage into them and never run stable. the k6-2+ was a bit better due to its .18 core but the k-6 archatecture was never ment to go more than 600 according to my mate dave! not like the thunderbird core which is one of the most o/cable ever!

scotter...somebody lite the fuse on your tampon?

I have several K6-2 cpu's, and I know 'personally' several others that have not been able to O/C K6-2 processors with any real success.

Yes, I will agree there have been some success stories, and I have seen a couple, but in my opinion (I am intitled to that, arn't I?..) the majority of the K6-2 series did not O/C well,,as compaired to the more modern K6-2+, K6-III and the Athlons with the .18 micron core.

I will continue to express my opinions, until and unless the powers that be here at SysOpt require that I stop doing so.

Suck on that for awhile.

now lets play nice. I personally am running a K6-2 333 at 500 with no voltage increase.

scotter · 08-22-2001, 08:03 PM

unless I just can not read correctly Fierra asked for help not hey those chips dont overclock bla de bla bla bla etc etc

I'm just tired of seeing that kind of reply to a post, He asked for help if you want to help him then do so if not why post ?

In response to the many suggestions and conclusions regarding K6 processors from AMD, I must point out that most of these are false.
I have had numerous K5-K6 CPUs, and all of them were overclockable. Heat does cause a problem, but if you install an internal fan in your chasis then you will have better results. I have currently a K6-400 overclocked to 450 that has been excellent and caused no problems. If you have a K6 then please go ahead and get your extra 50-100 Mhz.

Bovon · 08-23-2001, 01:27 AM

fierra, the K6-2 series cpu's did not overclock too good. A few people have been able to overclock some of them but most do not. I have a K6-2 500, and tried running it at 550 and after raising the core voltage to 2.8 volts (normal is 2.2 volts) I gave up. It would work, but was never stable in Windows.

The main reason is, the core is made with a .25 micron configuration. The later K62+ and K6-III series had a newer .18 micron core, and overclocked better.

If you can get 50 more mhz out of your K6-2 you will have done pretty good...and that will come from raising the core voltage a good bit. This will take a better heat sink than what comes with them.

MOST AMD K6-2 cpu's do not overclock very high, most of them usually only reach 50-100mhz above their rated speed. This is due to the aforementioned manufacturing process mainly. The main reason some people have great success overclocking them is quite simple, sometimes a processor manufacturer introduces a higher clocked cpu but there is still a demand for the lower clocked components. So instead of running a manufacturing process for the older parts they just re-mark the higher speed proc's. Read somewhere intel did this a LOT with the PII with the Deschutes core, the PII-400 were marked down to 333mhz quite often.

Bovon IS entitled to his opinion, it's kind of like someone trying to overclock PC133 to 166mhz, it might work in rare circumstances but it rarely does so it should be mentioned so they know their RAM has limitations and not to expect it to happen all the time.

fierra: A slight increase in core voltage might do the trick (as lemonhead said), else you could also try rasing the FSB a little, maybe something in the 533mhz vicinity might work.
