Repeat: "Check with someone more knowledgeable than me"; and BTW that is the answer to your question too! :?

Really? I purchased two K6-III+ATZ 400 CPUs off Ebay recently and they run fine @600 and 2.1volts (see my post http://www.k6plus.com/index.php?name=PN ... pic&t=1435)

Well, after roughly four or five months, I started getting weird errors with Internet Explorer and finally figured out it was the processor and "declocked" it to 500 MHz. Voila, no more errors. .
Yikes! Now you have me worried: I have my two CPUs both on 2.1volts and running 550 and 600 quite stable (in fact, more stable than my other K6-2 CPUs ever were on the same boards!!)

What sort of cooling did you use?

The one processor that he (half) baked, was running with passive cooling. His principal concern is noise, so he was trying to see what performance he could get that way.

K, found your answer about burning in. Go to the "Software and Tweaking" section, page 1 near the bottom of the page, you will find a post labeled "Overclocking Stability Help" by "Darbykidd". He got expert advice on the subject.

Still playing around with this CPU...

Currently running at 500MHz on a 100KHz FSB with core voltage of 1.5V and CPU temperature is low to mid 30s C. Not too bad for Florida summertime.

What size heat sink are you using? You should be able to get it cooler than that I think. PS I lived in Florida for three years, it is no worse than summer here in Toronto strangely enough.

What about humidity though?? :D

Well, I live in the driest state on the driest continent and we regularily get 46-48 degrees celcius in the peak of summer - I'm going to be very interested in what my K6-3's do then 8)

Mind you I tend to spend most of my time in the pool when that happens anyway 8)

Latest on the continuing saga...

Finally got around to replacing my mixed bag of RAM modules on the motherboard. Removed the PC100 and added 2 old PC133 modules made by Xerox (2 modules of 128MB each).

Reset the multiplier jumper to 4, left the FSB jumper on 100MHz. In the BIOS, played around with changes to the FSB (112MHz, 124MHz, and 133MHz). After bootup, I used K6Speed to reset the multiplier to 5 for the 112MHz FSB (560MHz) and 4.5 for the 124MHz (558MHz). At 112MHz and 124MHz, ran stable and was able to complete Symantec Antivirus scan, Adaware scan, and Spybot scan. (I have found these three programs, along with Goback, to be excellent and fast indicators of stability problems.) No stability problems indicated by any of these three programs and Goback had no problems.

At 133MHz FSB, the PC booted into W2KPro, but the video card apparently did not like the "new" bus speed. Screen resolution was reset to the default. Did not seem unstable, but I did not stay there at that FSB very long. I am not very experienced with FSB overclocking and did not want to damage my AGP card - even though it is not an expensive card. Not sure whether to pursue this or not.

Any comments or suggestions would be appreciated.

To Jim,

My HSF is a pretty basic Socket 7 stuff. Not branded and the fan is sized 50mm x 50mm x 10mm. Don't know what the air flow is since it is unbranded and I bought it used. :roll:

The HS is 50mm x 50mm x 25mm (I believe that is correct on the height).

Sorry for the delay in responding. :oops:

Dot's a small one. Bigger is better in this case. What you can use depends upon the processor socket location on your mobo. Some like my ASUS P5A-B can't take more than a 50mm square base heatsink, because anything bigger will conflict with the AGP card. (Unless the AGP card is a very short one). My DFI's on the other hand can take 80mm fan / heatsink combos because the processor socket is located down at the lower right part of the mobo.

In any case, I would recommend a taller heatsink, 25mm is approximately one inch, I like the ones that are 1 & 5/16 inches tall, with fins spaced about 3/32 of an inch apart. Right now I am running at 26 C. Every 10 C is supposed to halve the life of your processor I have heard.

I am also very inexperienced at OCing the FSB. The only comment I will make about what you have achieved, is that from what I have heard, most boards won't boot when the FSB is set at 133; so you are doing better than most.

BTW, did you burn it in - in accordance w/ Blue's instructions? If so could you give me any details, cause I have to burn in mine on both SP2 & SP3. Thanks.

Checked the HS height when I got home - it is 20mm, not 25mm.

With the ATX board, my CPU is fortunately not close to my AGP/PCI slots. It's just surrounded by capacitors. I've got more room on the length than on the width.

I was able to resupply myself with AS5 last week (been out for a while and had to use "the other stuff") and I already have other HSFs sitting around. Will have to try one now.

No, I have not done the CPU burn-in yet. I don't leave my PCs running unattended (meaning I don't leave the house when they are running). He recommended a couple of continuously running days and I have not been able to work that into my schedule. I downloaded a free version of Winamp and installed it. I do plan to burn-in, though.

K, just did a measure. Used inches before cause you are in the States and thought that is what you would be using there. 60mm square base by 33mm tall, with fins spaced 2mm apart is what I am using on my DFIs; which = 26 - 35 C depending on load and ambient.

Thanks Jim.

Inches, millimeters - doesn't really matter to me, I just go with the flow. My place of employment uses the metric system, but most other state-side businesses still use the English system.

Latest...

Currently running 4.5 x 124MHz FSB for 558MHz speed. No motherboard L2 cache. Have been alternating core voltage from 1.8V to 2.1V as I switch from usage/operations to a CPU burn-in program (using 2.1V for it).

Discovered that the board's L2 cache will work at a FSB of 112MHz! Same 1.8V setting, but may give 1.7V a try.

How do I sort out the advantages/disadvantages of each setting?

Note to Jim:
I am using a freebie for the CPU stressing. I foud it at http://www.majorgeeks.com. See this site for the specific program: http://www.majorgeeks.com/CPU_Burn-in_d3921.html

I am looking for a FSB changing program - something like SoftFSB - that will work in W2KPro. Any suggestions?
