I have a AMD K6 450mhz & after sitting there running windows

I restart goto to bios look at the cpu temp and it 60 degrees cesius or 140 degrees Fahrenheit!:mad:

now i find thiis to be not true because i touched the cpu with out burning my finger so i was wondering if any one could help me find out whats wrong and hopefully i fix it:D

First of all:

WELCOME TO THE FORUMS!! :D

What kind of hsf(heatsink fan) are you running on that K6-2? You can get you the cheapest T-bird hsf that you can find, such as a chrome orb and cool the heck out of that K6. I'm running an old Global Win FOP32 on mine with a small fan on it and my K6-2+ runs cool even at 550 mhz and 2.5 volts vcore.

it has the stock hsf on it , but the heatsink is big and the fan is running nicly, the thing i don't get is that i can touch the cpu but it does not feel hot!!

If it was installed without any thermal compound, you would have very poor het transfer to the hsf. Also, if it has been on there for quite a while, the thermal compound may have dried up and isn't doing it's job of helping to transfer the heat. It also might be some weird readings from the socket thermistor; with it giving you an inaccurate reading. That's just a few things that have popped up in my head.

muddocktor you hit the nail right on the head! i had a look at the cpu and heatssink & sure enough there was a shiny cpu and no thermal paste

Slap some thermal goop on there and watch the temps drop! You could get away with no thermal paste with the old pentium 1 and slower K6 procs but a K6-2 450 really needs some thermal paste to help with heat transfer. You might even be able to bump it up to 500 mhz or so once you have the heat problem licked.

When i have get the thermal paste tomorow & hopefully fix the problem, how do i go about overclocking it? i have a lot of overclocking experiance, (overclocking my old 166 and TNT2 m64) it there jumpers or bios? and what is the very highest i can go ? with the processer? in the CPU Reviews some one had a k6-2 450 to 900. I will be getting water cooling soon anyways:D

There where some people who removed the metal cap also.
Haven't done this myself, but seems to help a little.

this thing where u sand the cap off the cpu isn't that called lapping?

to make it cooler but im not realy willing to risk the chance of the cpu getting stuffed due to "over lapping"

Yeah I've taken the cap off these, it's different than lapping, lapping is smoothing out the cap with sandpaper etc, removing the cap is taking it off completely, leaving you with something that looks like an athlon. The CPU die is right there, and you have to take the same caution not to crack the core.

It gives you about 33-50 more stable Mhz usually. Max "POST" Mhz usually isn't much affected.

The heat spreader is held on top of the CPU by something that looks a bit like hot melt glue or RTV sealant, it's rubbery stuff, (but thermally conductive of course) and is just blodged at each corner of the plate and on top of the die. You can cut through it at each corner with a thin sharp blade such as a single edged razor blade, takes a while sometimes, then when you are through all four corners it usually twists off the die neatly, or may already be loose.

Dunno quite what it does for temps since none of my K6-2 boards have thermal monitoring. I suspect it helps if you've got a good heatsink. however if your heatsink was kind of marginal the lower thermal mass might make things a little worse.

I'd beleive 800Mhz by the way, but would be sceptical about 900 without more details since the fastest boards I know of based on MVP3s or MVP4s usually, do up to 133 FSB and the chips do a max 6x multiplier.

That's not to say a board mod might not work to get a 150 FSB or something. K6-2s seem to come in one of two types for overclocking, some will go to a certain point and then start getting errors at the next step, while remaining seemingly cool enough. Others, will go and go but will heat up real warm, and seem like as long as you can figure how to keep them cool enough they'll keep taking all the voltage and Mhz you can throw at them.

The highest realistic overclocks with the K6-2 procs is usually 50-100 mhz max over the rated speed. The ones that do the best seem to be the K6-2+ and K6-3+ series of mobile chips because they were built on a .18 micron process instaed of the .25 micron process the rest of the K6-2 series were built on. BTW, to get a 6X multiplier on a socket 7 board, AMD remapped the 2X multiplier to give a 6.0 X multiplier value. Hope this helps you out.
