I just installed the K6-2 350mhz with the correct jumpers. Now I want to overclock it to at least 400mhz or higher with just the factory fan/heatsink. I have a Delhi 3 motherboard and 160MB pc 66/100 sdram. I just need the correct jumper settings.

One more thing, is the fan on the heat sink supposed to blow air to or away from the heatsink?

Many thanks in advance to whoever can help me.

Actually with your 400 mhz nowadays, you can not do anything with it, unless you still stick with Windows NT 4.0; and or you just use with with surfing the internet, or using Office work proceduring, or any light duty operation. With the current Duron falling prices, it is better to just head for a at least 1 Ghz Duron and leave this old 350mhz as is without being overclocked. Reason: maybe you will use it as a CD-RW task in which you have the option of testing and burning; or maybe you may use it for some light duty task but requires long hours of operation without having to babysit it. With falling prices of network components as well as CD-RW drive, it is easy to use two computer with only one monitor for a lot of task, overclocking this 350 mhz requires consumption of electricity the same as running a more powerful Duron 1 Ghz. So just better to just leave this old 350 mhz alone without being overclocked for some CD burning task or some other task that you can find to give to it.

What a crock!
At one time buddy 350mhz cpus were the newest things that did every application possible. Dont listen to this dipstick, you can overclock that thing to at least 450 without having to change the fan. And the fan blows air onto the cpu

So????
Are you going to use mind over matter to cool this OC project? Odds are the CPU won't work beyond 400 even if you do have extra cooling. Do some more reading before you blow your K6-2.
Good luck .

It takes a crock to call someone else a crock. It takes a dipstick to call someone else a dipstick. 350 MHZ is outdated nowadays. You can use it for burning your CD while you are doing something else on your new at least 1 Ghz computer.

Sorry Happy User but the other guy is right and you are wrong, I have a Amd K6/2 350 myself and I can do anything I want with it.

My guess is, ectoplasme, you and any one else, soon you will have at least a 1.4 Ghz computer in your hands, and if it happens that you have your 20 GB 7200 rpm and those expensive G Force AGP card, plus your pci sound blaster live and your Video capture card if you have one, if you happen to have these things which are suitable for used on the new system with faster computer, then my guess would be you wil move these things onto your new at least 1.4 GHz computer system until you can go out there and buy better and faster hard drive, better and faster AGP card and sound card, etc. So then now your old 350 Mhz just sits there with some of your old ISA sound blaster card and an old 4 mb pci video and probably your old ISA 56k modem, (because you would use the faster and the newest PCI modem on your new and faster system). You say you would give this old system to someone who needs it. But this someone is just like you, this someone also just gets his/her new at least 1.4 Ghz computer and he/she is about to let his/her old 350mhz laying around for some CD-RW burning or for some other light duty task operation. So do you really mean when you say you will waste your time using these old 350 mhz computer to do most of your computing task? 350MHZ computer are outdated for some major tasks or works that require computers. Even the most simple photo image editing, you will probably want to do this on your new and faster computer, not to mention if you even try to watch those mpeg 4 movie. My guess would be that one year from now or even less than that, you will use this old 350 mhz for CD burning, and for WAV to mp3 conversion, or for extracting audio music CD into WAV, or any other tasks that requires less CPU usage power, but long hours of computing working. Then for example if you happen to use this old 350 mhz for CD music audio extraction, or even the WAV to mp3 conversion, you may want to run it at medium to slow speed to gain the most accurate Audio extraction quality, then this old 350 mhz would be running for several hours after several hours. Then what good does it do for you to overclock this thing if it only requires low CPU usage but long hour operating? So am I right or am I right?

I did a quick search for your motherboard & came up with a page that has all your jumper settings:

http://www.e4all.info/motherboards/delhi3_jumpers.htm

This particular page has CPU settings up to 350Mhz but no higher. Probably at the time, 350 was the fastest CPU available, so you're gonna have to experiment a little to clock up to 400Mhz - & there's no guarantee that it will work. It appears that this board will clock up to at least 500Mhz though -possibly even 600Mhz.

This would be my guess to run your system at 400Mhz:

for 100Mhz front side bus (host clock frequency):
J3 = 1-2
J4 = 1-2
J5 = 1-2

for 4.x multiplier (bus speed ratio):
J11 = 2-3
J12 = 1-2
J13 = 2-3

for PCI/host clock ratio:
(this sets the speed of the PCI bus which should be approx 33Mhz)
J2 = 1-2
J9 = 2-3

Your CPU voltage (CPU CoreVCC set) should remain unchanged.

Now, I've gotta throw my two cents into the pot. I'd like to take issue with another poster's claim that a 350/400 CPU is useless nowadays. Generally speaking, a 233MMX CPU is the minimum requirement for most applications, although some recommend more & some less. There are still plenty of people out there making do with 166 or 200Mhz systems & even some old 486 machines & chances are, they don't have near the amount of RAM that this guy has.

Mr Happy, I've read some of your other posts & your views on heatsinks, cooling & CPU speed are "unique" to say the least. Maybe you should stick to posting about things you're familiar with - I'm sure if you do some searching, you can find a Prozac or Paxil forum.

Have a nice day! :oP~

I’ve got a couple of K6 II 400MHz’s, a K6 250MHz, and a K6 II 300MHz. I’m not a gamer. I do a lot of photo editing with Photoshop. They are all capable of doing this as long as I use more than 256MB of RAM but they run much slower than my P4 1.7GHz Dell and my Athlon 1.4GHz.

I’ve been able to overclock my AMD K6s up to about 50MHz over their rating. I could overclock my 250MHz K6 a lot more than my 400MHz K6 II.

As a hobby or to give more life to your computer, Daniel Q, I think overclocking is an OK thing to do. I think you might get more bang for your buck with more RAM and/or a PCI ATA adapter card and an ATA 100 or 133 HDD.

Seriously, though, I find myself using my Athlon and P4 based computers a lot more than my old AMD K6s.

Geeez, Jason.
Is there some reason why you need to tlak to people like that? HappyUser is a absolutely correct. WinME requires a minimum of 160 Mhz. *BUT* 450 Mhz. if you ever want to use the movie maker and other incredibly fancy stuff. Many top of the line 3D games of today, have system requirements that range from 233 Mhz. to 450+ Mhz. in speed. Where have you been, the past couple of years?

Problem is that software and hardware add-on components change every 6 months or so, requiring more and more resources - to include speed.

YES - Any 300 Mhz. to 450 Mhz. system will work perfectly fine for email, surfing the web, most business applications, graphic applications, and so on. But you still need a decent chunk of memory for most of that (minimum of 128MB - or 256MB desired).

Don't forget though - you're running hardware that is becoming obsoletre faster and faster with every coming month.

As far as overclocking a 400 Mhz. chip is concerned, WITHOUT additional cooling - that's just sheer folly. There are SOOOOO many articles in this forum, addressing the importance of proper cooling for overclocking, that I'm a bit surprised that Daniel Q apparently read none of them. Anytime that you make a chip perform faster, you also tend to heat up the chip more during all operational times. HEAT is often the direct cause of "burning" out a chip - Duh. So, to overclock your 400 Mhz. chip to 450 Mhz., you definitely need better cooling. Buty to run it even faster, ay say 500 Mhz., you'd need PHENOMENAL cooling - with a heavy duty, large fan/heatsink combo on the chip, and a minimum of 3 additional case fans, to include the one that's already in the power supply.

You can't just increase the speed of your chip "magically" without doing other things to make that process safe. If you do, you'll be back on this forum in no time, complaining about a computer that won't work (due to a burnt out chip or severe system stability problems).

Hey Intel, AMD rulez!

What are the jumper settings t get it at 400mhz or 450mhz?

Daniel,

Didn't you even read my post?? Scroll up...the jumper settings are right there for ya!!!! & don't bother trying it at 450, you're wasting your time...

Ooops sorry dude. Are those setting safe with the stock fan?

Sorry response # 4 above is for Jason only.

I don't know much about computers and have lost the manuals that came with my old AMD K6-2 350 sold to me in 1999 by M Squared Systems. Does anyone know of a website where I might find info on it? I'm especially looking for information and diagram on the Baby AT Motherboard. I think the model number may be M598v3.6 There's an extra two wire (red & black) plug coming off the power supply to the second hard drive that I don't know where goes. This second hard drive, a 20GB Maxtor was installed by a pro, not me. This computer caught a virus in 2000 and I'm just now trying to fix it myself. I have it going now but it won't let me access the second hard drive. I appreciate any help you can give me. Thank you very much, Rob
