AMD K6-2 550 cpu temp?

[Racer7201]

I started having some problems with the system, slowing down, games jerky etc and decided to pick up a K6-2 550 today. I had a 450 and the price was right on the 550. M/B DFI K6BV3+. Put the new cpu in and started running system. Ran good for about 45 minutes, then BSOD and misc errors. Rebooted and checked cpu temp in the bios, 147 degrees F. Seems pretty high to me. Never could get it to run without errors after a few minutes. Put the 450 back in and temp runs around 127F. Settings were correct, 2.3v and reported as 550.
What's ya think?
Thanks, Jerry

There something wrong with your cpu/heatsink combo with your
550, it should run cooler then 450.
Mine is at 127F/42C at max even overclocked 582

You deffinately have a problem, Are you using thermal tape between the heatsink and CPU? If so, perhaps that is the problem. Use thermal paste. I have an amd K6-III AHX (2.4 vcore) that runs at 500@2.6 and 472@2.3 and 450@2.2 The temp never gets above 105F and rarely breaks 100F. When it does, I worry, but maybe that's just the overclocker in me. I use a GlobalWIN FEP-32 with silicon thermal compound, and I have popped the cap off my K6-III. Good luck, hope this helps.

Right now the temp is 127F after running for about an hour. So far I've changed power supplys, had the cpu/mb checked at the shop (ran 114F for about an hour with no case, on their test bench). I've tried 3 different fan/heatsink combos. Installed a fan case, tried blowing out/in. Blowing in seems to work the best. If I leave the case off, it will stay around 116/118. I even swapped my voodoo3 2k pci out with my old viper v330, just to make sure the card wasn't putting too much load on it. I was using thermal paste. This one doesn't have anything right now, but I think I'll put some on it. I'm running out of ideas.
Thanks, Jerry

It your case, try sucking air in from the front
and blowing out in the rear.
<...case..............> ->
<.....................> -> strong air current with extra fan
<.....................> -> air in from bottom left
<.....................>
<--------------------->
-> <--------------------->
-> <sucking air in------->
-> <--------------------->
There is so much heat from your component such as your HARDDRVE
which is most HOT
everything gives off heat including DIMM, VGA card, Snd card,
you name it.
Air from the front is much cooler so don't suck and blow air at the same time in the rear it like a green house effect it just get hotter
and hotter until all your component is fried.
The harddrive will then develop bad sector, your cpu will have brain damages causing random lockup.

After you solve this, you wanna overclock it right?
Do 97 x 2.0 which will be remapped to 6x
so = 582 mhz
and up the core V to 2.4
and you have a rock solid operation and yes
I do have same DFI motherboard K6BV3 REV.B
BTW: the slowdown maybe that you are lacking memory
how many do you have?
I have 32meg, and run like a crawl when playing Quake3D

Hyper99, what's your settings for 97? I only see 95 in the book. I currently have 128m ram. So far today, the highest its gotten is 134F after running for about 6 hours.

I had the same problem trying to cool the 550 which was running around 120 to 122F with a Globalwin fan. I actually don't consider it a big problem as I had a 350 running for years at about the same temp and the max temp for it was 60C whereas the 550 max is 70C.
I also am running my 550 @560, 112 FBS and a core volt of 2.2
I installed Rain and it seldom goes above 100F now.

 

[Hyper99]

You have a Rev A motherboard
It doesn't support 97Mhz Bus
The cpu monitor works in windows
I have a Rev B motherboard
cpu monitor doesn't work in windows
has 97mhz bus support
You can try 95 x 2.0 will be remapped to 6.0
= 570 slightly speed improvement and
up the voltage to 2.4
2.3 is only enought for 550mhz
Trust me, I've tried it myself at 2.3 at 570
lockup
I also have a K6 500, overclocked to 550
and Voltage from 2.2 to 2.6
So you see how much voltage is required for stability?
Your best best is +20mhz which is a little help you can if you want
just for fun.
I say 550 is just about as good due to 100mhz FBS which will equal to about the same.

Thanks Hyper99, I'll probably just leave it where it is for now. I installed CPUidle this morning and the immediately dropped from 124F to 109F. I think I'm going to move the case fan from the rear and modify the front of the case and let it suck air from the front instead of the rear where the hot air is going out.

 

[Hyper99]

I made a little mistake myself awhile back
having the air suck and blow in the rear
I must not be using my head right.
I then have both of them blow out air in the back instead
and that helped alot.
I must say it working very well.
As for overclocking a 500 is much better
runs hotter then a 550 thought
550 at 550 about 132F @ 2.3V
500 at 550 about 153F @ 2.6V
Thats when you are doing something intensive like playing Quake3D
at 100 percent workload.
