old K6 for emu machine

I am trying to overclock my old K6 (NOT K6-2, as in no 3D-NOW) as much
as possible to use it for an emu machine and to record TV shows w/ the
TV tuner card. The stock speed is 300 MHz and it's one of the new
(well, relatively) .25 micron K6 chips. First, would you recommend
lapping the heat spreader, which is definitely not too flat? Second,
it works at 338, POSTs and boots into Windows at 375 when there's a
good layer of Arctic Silver, but crashes before getting to the desktop
w/o Arctic Silver. The heatsink is never really that hot. With the
arctic silver, it takes a while to start making errors on my
overclocking tests. Does this sound like I need more volts or more
cooling?

Lastly, since I am really not that worried about frying this POS, I
tried raising the volts to 2.8, the next higher setting on my board
after 2.2. Doesn't POST, but isn't fried-works again when I put it
back down. Any ideas why it wouldn't POST at 2.8?

Voltage too high? And I don't think you will be able to digitize and
record tv without a hell of a hardware digitizer/compressor; your CPU is
not only slow, but has non of the extra instructions that are especially
useful for streaming media. And then there is the question about how big
and how fast your hard drive is.

You're going to need lots of disk space because the K6 is not going to be
fast enough to do any significant encoding on the fly no matter how much of
an overclock you manage; unless you have a separate hardware MPEG encoder.

Might help a little.

I don't know what you mean by "good layer." What you want is the minimum
amount that will just fill the micro gaps.

What do you mean by "w/o Arctic Silver?" Nothing?

It sounds like the heat isn't getting TO the heatsink. Perhaps too much
thermal compound.

2.8 is too high.

I had a K6-2 450 (the "newer" ones with CTX core) and an ATI All-In-Wonder
128. I can record TV on it Ok but it was impossible to have it encode even
Mpeg1 on the fly. Everything was done in AVI and I have to encode them
later, needless to say with a 8GB disk at that time storage was running out
after 1 hour of recording, which was actually fine for most shows.

I ran Ultra-HLE (the N64 emu) with a 3dfx voodoo 2 card, and it was SLOW. I
think the FPU was only as fast as a Pentium MMX 233, but it was OK for
running Quake 2 with the 3dfx driver and 3dnow quake2 exe. SNES 9x ran ok
and only slows down sometimes. I could not get Bleem (PS emu) to work at
all.

I heard people running K6-2 and K6-3 at 2.8v no prob, not because they want
to but because they were using old socket 7 (not super socket 7) mobos that
only supply 2.8 or 3.3 vcore , but I have never tried it myself, fearing
that it will ruin my shiny new K6-2 (back then)

newegg has a 500 k62 for $16 postpaid.

Yes. The two big surprises one discovers when they first try video
recording are just how HUGE raw video is and how much processing power it
takes to encode.

The Atari800Win emu will run 100% speed on my mobile P-II 300 so I'm sure
your K6-2 450 could handle it.

I overclocked a CTX core with 2.8 volts and it was glorious for the hour or
so it survived.

Moot point really since his isn't a CTX core and it won't post at 2.8 volts.

the 500s are worse still for overclocking
whatever i did with my 500 i could not get to even 533 mhs with it...

K62's are even worse at overclocking then Palmoninos are... and the
palmonino my mate got me to overclock went about as far as the rust bucket
round the corner!

I got my K6-2 350 running stable at 450Mhz (4.5 X 100) with 2.8v going
across it. :-P

well that was just my findings...
my motherboard mine was on was **** beyond recognition...
compaq **** thing

no voltage adjustment tinker or fiddle could will that POS to 550mhz

give it its due tho... it was 100% rock solid at stock speed

Start lapping.... it's a labor of love and it'll really help to level the
spreader, which as you noted are ever, ever flat.

Whay more cooling!

It's been quite some time now that I've fooled with k6's. But they like to
be kept cool too. Everything you described above points to over heating.
Lap the dog out of the processor and then the heat sink.

Have fun.

Instant over heating? Maybe it's not a valid vcc option?
